Summary of Significant Accounting Policies	Dec. 31, 2022
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Regions Financial Corporation (“Regions” or the “Company”) provides a full range of banking and bank-related services to individual and corporate customers through its subsidiaries and branch offices located across the South, Midwest and Texas as well as delivering specialty capabilities nationwide. Regions is subject to the regulations of certain government agencies and undergoes periodic examinations by certain of those regulatory authorities. The accounting and reporting policies of Regions and the methods of applying those policies that materially affect the consolidated financial statements conform with GAAP and with general financial services industry practices. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the balance sheet dates and revenues and expenses for the periods presented. Actual results could differ from the estimates and assumptions used in the consolidated financial statements including, but not limited to, the estimates and assumptions related to the allowance for credit losses, fair value measurements, intangibles, residential MSRs and income taxes. Regions has evaluated all subsequent events for potential recognition and disclosure through the filing date of this Annual Report on Form 10-K. During 2022, the Company adopted new accounting guidance related to several topics. All prior period amounts impacted by guidance that required retrospective application have been revised. Certain amounts in prior period financial statements have been reclassified to conform to the current period presentation, except as otherwise noted. These reclassifications are immaterial and have no effect on net income, comprehensive income (loss), total assets or total shareholders’ equity as previously reported. BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of Regions, its subsidiaries and certain VIEs. Significant intercompany balances and transactions have been eliminated. Regions considers a voting rights entity to be a subsidiary and consolidates it if Regions has a controlling financial interest in the entity. VIEs are consolidated if Regions has the power to direct the activities of the VIE that significantly impact financial performance and has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE (i.e., Regions is the primary beneficiary). The determination of whether Regions is the primary beneficiary of a VIE is reassessed on an ongoing basis. Investments in companies which are not VIEs but in which Regions has more than minor influence over the operating and financial policies, are accounted for using the equity method of accounting. Investments in VIEs, where Regions is not the primary beneficiary of a VIE, are accounted for using either the proportional amortization method or the equity method of accounting. These investments are included in other assets. The maximum potential exposure to losses relative to investments in VIEs is generally limited to the sum of the outstanding balance, future funding commitments and any related loans to the entity. Loans to these entities are underwritten in substantially the same manner as are other loans and are generally secured. Refer to Note 2 for additional disclosures regarding Regions’ significant VIEs. CASH EQUIVALENTS AND CASH FLOWS Cash equivalents represent assets that can be converted into cash immediately. At Regions, these assets include cash and due from banks, interest-bearing deposits in other banks, and federal funds sold and securities purchased under agreements to resell. Cash flows from loans, either originated or acquired, are classified at that time according to management’s intent to either sell or hold the loan for the foreseeable future. When management’s intent is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management’s intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows. The following table summarizes supplemental cash flow information for the years ended December 31: 2022 2021 2020 (In millions) Cash paid during the period for: Interest on deposits and borrowed funds $ 303 $ 185 $ 408 Income taxes, net 336 367 132 Non-cash transfers: Loans held for sale and loans transferred to other real estate 21 14 31 Loans transferred to loans held for sale 22 240 275 Loans held for sale transferred to loans 24 277 1 Properties transferred to held for sale 6 38 33 SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL AND SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE Securities purchased under agreements to resell and securities sold under agreements to repurchase are treated as collateralized financing transactions. It is Regions’ policy to take possession of securities purchased under resell agreements either through direct delivery or a tri-party agreement. DEBT SECURITIES Management determines the appropriate accounting classification of debt securities at the time of purchase, based on intent, and periodically re-evaluates such designations. Debt securities are classified as held to maturity when the Company has the intent and ability to hold the securities to maturity. Debt securities held to maturity are presented at amortized cost. Debt securities not classified as held to maturity are classified as available for sale. Debt securities available for sale are presented at estimated fair value with changes in unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income (loss). See the “Fair Value Measurements” section below for discussion of determining fair value. The amortized cost of debt securities classified as held to maturity and available for sale is adjusted for amortization of premiums and accretion of discounts to maturity, or first call date when applicable, using the effective interest method. Such amortization or accretion is included in interest income on securities. Realized gains and losses are included in net securities gains (losses). The cost of securities sold is based on the specific identification method. For debt securities available for sale, the Company reviews its securities portfolio for impairment and determines if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis. Subsequent activity related to the credit loss component (e.g. write-offs, recoveries) is recognized as part of the allowance for credit losses on debt securities available for sale. Securities held to maturity are evaluated under the allowance for credit losses model. For securities which have an expectation of zero nonpayment of the amortized cost basis (e.g. U.S. Treasury securities or agency securities), the expected credit loss is zero. Refer to Note 3 for further detail and information on securities. LOANS HELD FOR SALE Regions’ loans held for sale primarily includes commercial loans, investor real estate loans, and residential real estate mortgage loans. Loans held for sale are recorded at either estimated fair value, if the fair value option is elected, or the lower of cost or estimated fair value. Regions has elected to account for residential real estate mortgages originated with the intent to sell at fair value. Intent is established for these conforming residential real estate mortgage loans when Regions enters into an interest rate lock commitment. Gains and losses on these residential mortgage loans held for sale for which the fair value option has been elected are included in mortgage income. Management has elected the fair value option for certain commercial loans originated with the intent to sell and gains and losses on those loans are included in capital markets income. Regions also transfers certain commercial, investor real estate, and residential real estate mortgage portfolio loans that were originally recorded as held for investment to held for sale when management has the intent to sell in the near term. These loans held for sale are recorded at the lower of cost or estimated fair value. At the time of transfer, write-downs on the loans are recorded as charge-offs when credit related and non-interest expense or non-interest income (dependent on loan type) when not credit related and a new cost basis is established. Any subsequent lower of cost or market adjustment is determined on an individual loan basis. Gains and losses on the sale of non-performing commercial and investor real estate loans are included in other non-interest expense. See the “Fair Value Measurements” section below for discussion of determining estimated fair value. LOANS Regions' loans balance is comprised of commercial, investor real estate and consumer loans. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered loans held for investment (or portfolio loans). Loans held for investment are carried at amortized cost (the principal amount outstanding, net of premiums, discounts, unearned income and deferred loan fees and costs). Regions elected to exclude accrued interest receivable balances from the amortized cost basis. Interest receivable is included as a separate line item on the balance sheet. Interest income on all types of loans is accrued based on the contractual interest rate and the principal amount outstanding using methods that approximate the interest method, except for those loans classified as non-accrual. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the contractual or estimated lives of the related loans as an adjustment to the loans’ constant effective yield, which is included in interest income on loans. Direct financing, sales-type and leveraged leases are included within the commercial portfolio segment. See Note 4 for further detail and information on loans and Note 13 for further detail and information on leases. Regions determines past due or delinquency status of a loan based on contractual payment terms. Commercial and investor real estate loans are placed on non-accrual if any of the following conditions occur: 1) collection in full of contractual principal and interest is no longer reasonably assured (even if current as to payment status), 2) a partial charge-off has occurred, unless the loan has been brought current under its contractual terms (original or restructured terms) and the full originally contracted principal and interest is considered to be fully collectible, or 3) the loan is delinquent on any principal or interest for 90 days or more unless the obligation is secured by collateral having a net realizable value (estimated fair value less costs to sell) sufficient to fully discharge the obligation and the loan is in the legal process of collection. Factors considered regarding full collection include assessment of changes in borrower’s cash flow, valuation of underlying collateral, ability and willingness of guarantors to provide credit support, and other conditions. Charge-offs on commercial and investor real estate loans are primarily based on the facts and circumstances of the individual loan and occur when available information confirms the loan is not or will not be fully collectible. Factors considered in making these determinations are the borrower’s and any guarantor’s ability and willingness to pay, the status of the account in bankruptcy court (if applicable), and collateral value. Commercial and investor real estate loan relationships of $250,000 or less are subject to charge-off or charge down to estimated fair value at 180 days past due, based on collateral value. Certain equipment finance loans are subject to charge-off at 120 days past due. Non-accrual and charge-off decisions for consumer loans are dictated by the FFIEC's Uniform Retail Credit Classification and Account Management Policy which establishes standards for the classification and treatment of consumer loans. The charge-off process drives consumer non-accrual status. If a consumer loan secured by real estate in a first lien position (residential first mortgage or home equity) becomes 180 days past due, Regions evaluates the loan for non-accrual status and potential charge-off based on net loan to value exposure. For home equity loans and lines of credit in a second lien position, the evaluation is performed at 120 days past due. If a loan is secured by collateral having a net realizable value sufficient to fully discharge the obligation, then a partial write-down is not necessary and the loan remains on accrual status, provided it is in the process of legal collection. If a partial charge-off is necessary as a result of the evaluation, then the remaining balance is placed on non-accrual. Consumer loans not secured by real estate are generally charged-off at either 120 days past due for closed-end loans, 180 days past due for open-end loans other than credit cards or the end of the month in which the loan becomes 180 days past due for credit cards. When loans are placed on non-accrual status, the accrual of interest, amortization of loan premium, accretion of loan discount and amortization/accretion of deferred net loan fees/costs are discontinued. When a commercial or investor real estate loan is placed on non-accrual status, uncollected interest accrued in the current year is reversed and charged to interest income. Uncollected interest accrued from prior years on commercial and investor real estate loans placed on non-accrual status in the current year is charged against the allowance for loan losses. When a consumer loan is placed on non-accrual status, all uncollected interest accrued is reversed and charged to interest income due to immateriality. Interest collections on commercial and investor real estate non-accrual loans are applied as principal reductions. Interest collections on consumer non-accrual loans are recorded using the cash basis, due to immateriality. All loans on non-accrual status may be returned to accrual status and interest accrual resumed if all of the following conditions are met: 1) the loan is brought contractually current as to both principal and interest, 2) future payments are reasonably expected to continue being received in accordance with the terms of the loan and repayment ability can be reasonably demonstrated, and 3) the loan has been performing for at least six months. Purchased Loans Purchased loans are recorded at their fair value at the acquisition date. Purchased loans are evaluated and classified as either PCD, which indicates that the loan has experienced more than insignificant credit deterioration since origination, or non-PCD loans. For PCD loans, the sum of the loans' purchase price and allowance for credit losses, which is determined using the same methodology as originated loans, becomes their initial amortized cost basis. For non-PCD loans, the difference between the fair value and the par value is considered the fair value mark. The non-credit discount or premium related to PCD loans and the fair value mark on non-PCD loans is accreted or amortized into interest income over the contractual life of the loan using the effective interest method. Subsequent changes in the allowance to the PCD and non-PCD loans are recognized in the provision for credit losses. TDRs TDRs are loans in which the borrower is experiencing financial difficulty at the time of restructuring, and Regions has granted a concession to the borrower. TDRs are undertaken in order to improve the likelihood of recovery on the loan and may take the form of modifications made with the stated interest rate lower than the current market rate for new debt with similar risk, other modifications to the structure of the loan that fall outside of normal underwriting policies and procedures, or in limited circumstances forgiveness of principal and/or interest. Insignificant delays in payments are not considered TDRs. TDRs can involve loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. TDRs are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product type as discussed in the “Loans” section above. The CAP was designed to evaluate potential consumer loan participants as early as possible in the life cycle of the troubled loan (as described in Note 5). Many of the modifications are finalized without the borrower ever reaching the applicable number of days past due, and therefore the loan may never be placed on non-accrual. Accordingly, given the positive impact of the restructuring on the likelihood of recovery of cash flows due under the modified terms, accrual status continues to be appropriate for these loans. As provided in the CARES Act passed into law on March 27, 2020, and subsequently extended through the Consolidated Appropriations Act signed into law on December 27, 2020, certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020, through the earlier of 60 days after the end of the pandemic or January 1, 2022, were eligible for relief from TDR classification. Regions elected this provision of both Acts; therefore, modified loans that met the required guidelines for relief were not considered TDRs. ALLOWANCE Regions adopted CECL on January 1, 2020, which replaced the incurred loss methodology to estimate the allowance with the expected loss methodology. Regions elected not to estimate an allowance on interest receivable balances because the Company has non-accrual polices in place that provide for the accrual of interest to cease on a timely basis when all contractual amounts due are not expected. The allowance is intended to cover expected credit losses over the contractual life of loans measured at amortized cost, including unfunded commitments. Management’s measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and R&S forecasts that affect the collectability of the reported amount. For periods beyond which Regions makes or obtains such R&S forecasts, Regions reverts to historical credit loss information. Regions maintains an appropriate level of allowance that falls within an acceptable range of estimated losses, measured in accordance with GAAP. Management's determination of the appropriateness of the allowance is based on many factors, including, but not limited to, an evaluation and rating of the loan portfolio; historical loan loss experience; current economic conditions; collateral values securing loans; levels of problem loans; volume, growth, quality and composition of the loan portfolio; regulatory guidance; R&S economic forecasts; and other relevant factors. Changes in any of these factors, assumptions, or the availability of new information, could require that the allowance be adjusted in future periods, perhaps materially. Loss forecasting models are built on historical loss information and then applied to the current portfolio. Outputs from the loss forecasting models in combination with Regions' qualitative framework, and other analyses are used to inform management in its estimation of Regions' expected credit losses. Actual losses could vary, perhaps materially, from management’s estimates. The entire allowance is available to cover all charge-offs that arise from the loan portfolio. Regions' allowance calculation is a significant estimate. Regions uses its best judgment to assess economic conditions and loss data in estimating the allowance and these estimates are subject to periodic refinement based on changes in underlying external or internal data. Therefore, assumptions and decisions driving the estimate may change as conditions change. These assumptions and estimates are detailed below. R & S forecast period During the two-year R&S forecast period, Regions incorporates forward-looking information by utilizing its internally developed and approved Base economic forecast. The scenario is developed by the Chief Economist and approved through a formal governance process. The Base forecast considers market forward/consensus information and is consistent with the Company's organization-wide economic outlook. When appropriate, additional scenarios, including externally created scenarios, are considered as part of the determination of the allowance. Reversion period Regions utilizes an exponential reversion approach that reverts to TTC rates derived from the simple average of all historical quarterly observations for PD, LGD, EAD and prepayment rates. The length of the reversion period differs by class of financing receivable. Historical loss period Regions does not adjust historical loss information for existing economic conditions or expectations of future economic conditions for periods that are beyond the R&S period. Regions utilizes internal historical loss information; however, there are certain loan portfolios that also benefit from the use of external or other reference data due to identified limitations with internal historical data. Contractual life Regions estimates expected credit losses over the contractual life of a loan. Regions defines contractual life for non-revolving loans as contractual maturity, net of estimated prepayments and excluding expected extensions, renewals and modifications unless 1) Regions has a reasonable expectation at the reporting date that it will execute a TDR with the borrower ("RETDR") or 2) extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by Regions. RETDR Regions individually identifies commercial and investor real estate loans for inclusion as RETDRs. The identification criteria are based on internal risk ratings and time to maturity. Regions typically does not identify consumer loans as RETDRs due to the insignificant time period between initial contact with a customer regarding a loan modification and when a TDR modification is consummated. The RETDR status extends the life of the loan past the contractual maturity and includes the allowance impact of interest rate concessions. Loans identified as RETDRs will be treated consistently from a modeling/reserving perspective as loans identified as TDRs. Contractual term extensions (borrower versus lender option to renew) Regions' consumer loan contracts do not permit automatic extensions or unilateral customer extensions, and Regions retains the right to approve or deny any extension requested from the borrower. As a result, extensions and renewal options are not included in the life of consumer loans for the purposes of calculating the allowance. Similarly, Regions does not include extension and renewal options in the life of commercial loans for the purposes of calculating the allowance, unless it is a RETDR. Most commercial products do not offer borrowers a unilateral right to renew or extend. Contractual life of credit card receivables Regions estimates the life of credit card receivables based on the amount and timing of payments expected to be collected. Regions' credit card allowance estimate only considers the amount of debt outstanding at the reporting date (the current position) because undrawn balances are unconditionally cancellable. Regions classifies credit card accounts into one of three payment patterns: dormant, transacting or revolving. The dormant accounts are idle, carry no balance, and do not contribute to the allowance. The transacting account holders tend to pay the entire balance due every month and are, therefore, subject to practically no interest charges. For transactor accounts, the current position balance is expected to be paid off in one quarter. The revolving accounts tend to be subject to interest charges, and their current position balance liquidates over time. Regions' credit card portfolio is comprised primarily of revolvers. Collateral-dependent loans Regions' collateral-dependent consumer loans are loans secured by collateral (primarily real estate) that meet the partial charge-down requirements disclosed within this section. Regions evaluates significant commercial and investor real estate loans that are in financial difficulty and secured by collateral to determine if they are collateral dependent. For any collateral-dependent loans that meet Regions' specific allowance criteria (see below), Regions will calculate the allowance based on the fair value of collateral methodology. For collateral-dependent consumer, commercial and investor real estate loans that do not meet Regions' specific allowance criteria (as described below), Regions considers the value of the collateral through the LGD component of the loss model based on collateral type. Credit enhancements Regions' estimate of credit losses reflects how credit enhancements, other than those that are freestanding contracts, mitigate expected credit losses on financial assets. In the event that a credit enhancement arrangement is considered to be a freestanding contract, Regions excludes the credit enhancement from the related loan when estimating expected credit losses. Unfunded commitments and other off-balance sheet items Regions records a liability or allowance for credit losses for the unfunded portion of a loan commitment in the event that the issuer does not have the unconditional right to cancel the commitment. For an unfunded commitment to be considered unconditionally cancellable, Regions must be able to, at any time, with or without cause, refuse to extend credit. The liability is measured over the full contractual period for which Regions is exposed to credit risk through a current obligation to extend credit. In determining the liability, management considers the likelihood that funding will occur, and if funded, the related expected credit losses under the allowance model. Regions' off-balance sheet unfunded commitments in the form of home equity lines, standby letters of credit, commercial letters of credit and commercial revolving products that are deemed to be conditionally cancellable will include unfunded balances within the allowance estimate. Future advances from certain unfunded commitments and other revolving products where Regions does have the unconditional right to cancel these agreements will not be included. CALCULATION OF ALLOWANCE FOR CREDIT LOSSES Pooled allowances The allowance is measured on a collective (pool) basis when similar risk characteristics exist. Segmentation variables for commercial and investor real estate segments include product, loan size, collateral type, risk rating and term. Segmentation variables considered for consumer segments include product, FICO, LTV, age, TDR status, etc. The allowance is estimated for most portfolios and classes using econometric models to estimate expected credit losses. In general, discounted cash flow models are not used for the purpose of estimating expected losses for the purpose of the ACL. Most of the econometric models include PD, LGD, and EAD components. Less complex estimation methods are used for smaller loan portfolios. Specific allowances Due to their size, complexity and individualized risk characteristics and monitoring, the allowance for significant non-accrual commercial and investor real estate loans (including TDRs) and unfunded commitments is measured on an individual basis. Loans evaluated individually are not included in the collective evaluation. Regions generally measures the allowance for these loans based on the present value of estimated cash flows, considering all facts and circumstances specific to the borrower and market and economic conditions. The allowance measurement for collateral-dependent loans that meet the individually evaluated threshold is based on the fair value of collateral methodology. TDRs and RETDRs Loans identified as TDRs and RETDRs are included in their respective loan pools (if they do not qualify for specific evaluation) and losses are determined by allowance models. The effect of the interest rate concession on these loans is considered through a post-model adjustment. Qualitative framework While quantitative allowance methodologies strive to reflect all risk factors, any estimate involves assumptions and uncertainties resulting in some level of imprecision. Imprecision exists in the estimation process due to the inherent time lag between obtaining information, performing the calculation, as well as variations between estimates and actual outcomes. Regions adjusts the allowance considering quantitative and qualitative factors which may not be directly measured in the modeled calculations. Regions' qualitative framework provides for specific quantitatively supported model adjustments and general imprecision adjustments. Specific model adjustments capture highly specific issues or events that Regions believes are not adequately captured in model outcomes. General imprecision adjustments address other sources of imprecision that are not specifically identifiable or quantifiable to a particular loan portfolio and have not been captured by the model or by a specific model adjustment. Regions considers general imprecision in three dimensions; economic forecast imprecision, model imprecision, and process imprecision. Refer to Note 5 for further discussion regarding the calculation of the allowance for credit losses. LEASES LESSEES Regions' lease portfolio is primarily composed of property leases that are classified as either operating or finance leases with the majority classified as operating leases. Property leases, which primarily include office locations and retail branches, typically have original lease terms ranging from 1 year to 20 years, some of which may also include an option to extend the lease beyond the original lease term. In some circumstances, Regions may also have an option to terminate the lease early with advance notice. Regions includes renewal and termination options within the lease term if deemed reasonably certain of exercise. As most leases do not state an implicit rate, Regions utilizes the incremental borrowing rate based on information available at the lease commencement date to determine the present value of lease payments. Leases with a term of 12 months or less are not recorded on the balance sheet. Regions continues to recognize lease payments as an expense over the lease term as appropriate. Operating leases vary in term and, from time to time, include incentives and/or rent escalations. Examples of incentives include periods of “free” rent and leasehold improvement incentives. Regions recognizes incentives and escalations on a straight-line basis over the lease term as a reduction of or increase to rent expense, as applicable, within net occupancy expense in the consolidated statements of income. See Note 13 "Leases" for additional information. LESSORS Regions engages in both direct financing and sales-type leasing. Regions also has a portfolio of leveraged leases. These arrangements provide equipment financing for leased assets, such as vehicles and aircraft. At the commencement date, Regions (lessor) enters into an agreement with the customer (lessee) to lease the underlying equipment for a specified lease term. The lease agreements may provide customers the option to terminate the lease by buying the equipment at fair market value at the time of termination or at the end of the lease term. Regions' equipment finance asset management group performs due diligence procedures on the lease residual and overall equipment values as part of the origination process. Regions performs lease residual value reviews on an ongo

Disclosure Variable Interest Entities Schedule Of Equity Method Investments [Abstract]
Variable Interest Entities	Regions is involved in various entities that are considered to be VIEs, as defined by authoritative accounting literature. Generally, a VIE is a corporation, partnership, trust or other legal structure that either does not have equity investors with substantive voting rights or has equity investors that do not provide sufficient financial resources for the entity to support its activities. The following discusses the VIEs in which Regions has a significant interest. AFFORDABLE HOUSING TAX CREDIT INVESTMENTS Regions periodically invests in various limited partnerships that sponsor affordable housing projects, which are funded through a combination of debt and equity. These partnerships meet the definition of a VIE. Regions uses the proportional amortization method to account for these investments. Due to the nature of the management activities of the general partner, Regions is not the primary beneficiary of these partnerships. See Note 1 for additional details. Additionally, Regions has loans or letters of credit commitments with certain limited partnerships. The funded portion of the loans and letters of credit are classified as commercial and industrial loans or investor real estate loans as applicable in Note 4. A summary of Regions’ affordable housing tax credit investments and related loans and letters of credit, representing Regions’ maximum exposure to loss as of December 31 is as follows: 2022 2021 (In millions) Affordable housing tax credit investments included in other assets $ 1,238 $ 1,045 Unfunded affordable housing tax credit commitments included in other liabilities 511 348 Loans and letters of credit commitments 598 410 Funded portion of loans and letters of credit commitments 282 148 2022 2021 2020 (In millions) Tax credits and other tax benefits recognized $ 180 $ 165 $ 164 Tax credit amortization expense included in provision for income taxes 149 139 133 In addition to the investments discussed above, Regions also syndicates affordable housing investments. In these syndication transactions, Regions creates affordable housing funds in which a subsidiary is the general partner or managing member and sells limited partnership interests to third parties. Regions' general partner or managing member interest represents an insignificant interest in the affordable housing fund. The affordable housing funds meet the definition of a VIE. As Regions is not the primary beneficiary and does not have a significant interest, these investments are not consolidated. At December 31, 2022 and 2021, the value of Regions’ general partnership interest in affordable housing investments was immaterial.

The increase in the number of securities and the total amount of unrealized losses from year-end 2021 was primarily due to changes in market interest rates. In instances where an unrealized loss existed, there was no indication of an adverse change in credit on the underlying positions in the tables above. As it relates to these positions, management believes no individual unrealized loss represented credit impairment as of those dates. The Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, the positions before the recovery of their amortized cost basis, which may be at maturity. Gross realized gains and gross realized losses on sales of debt securities available for sale were immaterial for 2022. 2021 and 2020. The cost of securities sold is based on the specific identification method. As part of the Company's normal process for evaluating impairment, management did not identify any positions where impairment was believed to exist in 2022 or 2021 or 2020.

Allowance for Credit Losses	NOTE 5. ALLOWANCE FOR CREDIT LOSSES Regions determines the appropriate level of the allowance on a quarterly basis. The methodology is described in Note 1. Additionally, refer to Note 1 "Summary of Significant Accounting Policies" to the consolidated financial statements to the Annual Report on Form 10-K for the year ended December 31, 2019, for a description of the methodology prior to the adoption of CECL on January 1, 2020. Reflected in the allowance is the impact of the sale of $1.2 billion of unsecured consumer loans at the end of the third quarter of 2022 with an associated allowance of $94 million. In conjunction with the sale, the Company recognized a $63 million fair value mark recorded through charge-offs resulting in a net provision benefit of $31 million.

Commercial —The commercial portfolio segment includes commercial and industrial loans to commercial customers for use in normal business operations to finance working capital needs, equipment purchases or other expansion projects. Commercial also includes owner-occupied commercial real estate mortgage loans to operating businesses, which are loans for long-term financing on land and buildings, and are repaid by cash flow generated by business operations. Owner-occupied commercial real estate construction loans are made to commercial businesses for the development of land or construction of a building where the repayment is derived from revenues generated from the business of the borrower. Collection risk in this portfolio is driven by the creditworthiness of underlying borrowers, particularly cash flow from customers’ business operations, and is impacted by sensitivity to several other factors, such as market fluctuations in commodity prices. Investor Real Estate —Loans for real estate development are repaid through cash flow related to the operation, sale or refinance of the property. This portfolio segment includes extensions of credit to real estate developers or investors where repayment is dependent on the sale of real estate or income generated from the real estate collateral. A portion of Regions’ investor real estate portfolio segment consists of loans secured by residential product types (land, single-family and condominium loans) within Regions’ markets. Additionally, this category includes loans made to finance income-producing properties such as apartment buildings, office and industrial buildings, and retail shopping centers. Loans in this portfolio segment are particularly sensitive to the valuation of real estate. Consumer —The consumer portfolio segment includes residential first mortgage, home equity lines, home equity loans, consumer credit card, other consumer—exit portfolios and other consumer loans. Residential first mortgage loans represent loans to consumers to finance a residence. These loans are typically financed over a 15 to 30 year term and, in most cases, are extended to borrowers to finance their primary residence. Home equity lending includes both home equity loans and lines of credit. This type of lending, which is secured by a first or second mortgage on the borrower’s residence, allows customers to borrow against the equity in their home. Real estate market values as of the time the loan or line is secured directly affect the amount of credit extended and, in addition, changes in these values impact the depth of potential losses. Consumer credit card lending includes Regions branded consumer credit card accounts. Other consumer—exit portfolios includes lending initiatives through third parties consisting of loans made through automotive dealerships and other point of sale lending. Regions ceased originating new loans related to these businesses prior to 2020. Other consumer loans include other revolving consumer accounts, indirect and direct consumer loans, and overdrafts. Loans in this portfolio segment are sensitive to unemployment, inflation, and other key consumer economic measures. CREDIT QUALITY INDICATORS The following tables present credit quality indicators for the loan portfolio segments and classes, excluding loans held for sale, as of December 31, 2022 and 2021. The commercial and investor real estate portfolio segments' primary credit quality indicator is internal risk ratings which are detailed by categories related to underlying credit quality and probability of default. Regions assigns these risk ratings at loan origination and reviews the relationship utilizing a risk-based approach on, at minimum, an annual basis or at any time management becomes aware of information affecting the borrowers' ability to fulfill their obligations. Both quantitative and qualitative factors are considered in this review process. These categories are utilized to develop the associated allowance for credit losses. • Pass—includes obligations where the probability of default is considered low; • Special Mention—includes obligations that have potential weakness that may, if not reversed or corrected, weaken the credit or inadequately protect the Company’s position at some future date. Obligations in this category may also be subject to economic or market conditions that may, in the future, have an adverse effect on debt service ability; • Substandard Accrual—includes obligations that exhibit a well-defined weakness that presently jeopardizes debt repayment, even though they are currently performing. These obligations are characterized by the distinct possibility that the Company may incur a loss in the future if these weaknesses are not corrected; • Non-accrual—includes obligations where management has determined that full payment of principal and interest is in doubt. Substandard accrual and non-accrual loans are often collectively referred to as “classified.” Special mention, substandard accrual, and non-accrual loans are often collectively referred to as “criticized and classified.” Regions considers factors such as periodic updates of FICO scores, accrual status, days past due status, unemployment rates, home prices, and geography as credit quality indicators for the consumer loan portfolio. FICO scores are obtained at origination as part of Regions' formal underwriting process. Refreshed FICO scores are obtained by the Company quarterly for all consumer loans, including residential first mortgage loans. Current FICO data is not available for certain loans in the portfolio for various reasons; for example, if customers do not use sufficient credit, an updated score may not be available. These categories are utilized to develop the associated allowance for credit losses. The higher the FICO score the less probability of default and vice versa. The disclosure of credit quality indicators for loan portfolio segments and classes, excluding loans held for sale, is presented by credit quality indicator by vintage year. Regions defines the vintage date for the purposes of disclosure as the date of the most recent credit decision. In general, renewals are categorized as new credit decisions and reflect the renewal date as the vintage date. Loans that are modified as a TDR are considered to be a continuation of the original loan, therefore the origination date of the original loan is reflected as the vintage date. The following tables present applicable credit quality indicators for the loan portfolio segments and classes, excluding loans held for sale, as of December 31, 2022 and 2021. Classes in the commercial and investor real estate portfolio segments are disclosed by risk rating. Classes in the consumer portfolio segment are disclosed by current FICO scores.

AGING AND NON-ACCRUAL ANALYSIS The following tables include an aging analysis of DPD and loans on non-accrual status for each portfolio segment and class as of December 31, 2022 and December 31, 2021. Loans on non-accrual status with no related allowance are comprised of commercial loans that totaled $151 million and $127 million as of December 31, 2022 and 2021, respectively. Non–accrual loans with no related allowance typically include loans where the underlying collateral is deemed sufficient to recover all remaining principal.

Typical modifications include accommodations, such as renewals and forbearances. The majority of Regions’ commercial and investor real estate TDRs are the result of renewals of classified loans at an interest rate that is not considered to be a market interest rate. For smaller dollar commercial loans, Regions may periodically grant interest rate and other term concessions, similar to those under the consumer program described below. Regions works to meet the individual needs of consumer borrowers to stem foreclosure through its CAP. Regions designed the program to allow for customer-tailored modifications with the goal of keeping customers in their homes and avoiding foreclosure where possible. Modification may be offered to any borrower experiencing financial hardship regardless of the borrower’s payment status. Consumer TDRs primarily involve an interest rate concession, however under the CAP, Regions may also offer a short-term deferral, a term extension, a new loan product, or a combination of these options. For loans restructured under the CAP, Regions expects to collect the original contractually due principal. The gross original contractual interest may be collectible, depending on the terms modified. All CAP modifications are considered TDRs regardless of the term because they are concessionary in nature and because the customer documents a financial hardship in order to participate. As provided initially in the CARES Act and subsequently extended through the Consolidated Appropriations Act, certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020 through January 1, 2022 were eligible for relief from TDR classification. Regions elected this provision of both Acts; therefore, modified loans that met the required guidelines for relief are not considered TDRs and are excluded from the 2021 disclosures below. The following tables present the end of period balance for loans modified in a TDR during the periods presented by portfolio segment and class, and the financial impact of those modifications. The tables include modifications made to new TDRs, as well as renewals of existing TDRs. 2022 Financial Impact Number of Recorded Increase in (Dollars in millions) Commercial and industrial 50 $ 174 $ — Commercial real estate mortgage—owner-occupied 11 5 — Commercial real estate construction—owner-occupied — 3 — Total commercial 61 182 — Commercial investor real estate mortgage 5 48 — Commercial investor real estate construction — — — Total investor real estate 5 48 — Residential first mortgage 983 135 6 Home equity lines 94 6 4 Home equity loans 208 14 — Consumer credit card 4 — — Other consumer—exit portfolios — — — Other consumer 5 — — Total consumer 1294 155 10 1360 $ 385 $ 10 2021 Financial Impact Number of Recorded Increase in (Dollars in millions) Commercial and industrial 65 $ 116 $ — Commercial real estate mortgage—owner-occupied 28 11 — Commercial real estate construction—owner-occupied 2 2 — Total commercial 95 129 — Commercial investor real estate mortgage 8 77 — Commercial investor real estate construction — — — Total investor real estate 8 77 — Residential first mortgage 492 85 8 Home equity lines 7 1 — Home equity loans 72 6 — Consumer credit card 1 — — Other consumer- exit portfolios — — — Other consumer 80 3 — Total consumer 652 95 8 755 $ 301 $ 8

Transfers and Servicing of Financial Assets [Abstract]
Servicing of Financial Assets	NOTE 6. SERVICING OF FINANCIAL ASSETS RESIDENTIAL MORTGAGE BANKING ACTIVITIES The fair value of residential MSRs is calculated using various assumptions including future cash flows, market discount rates, expected prepayment rates, servicing costs and other factors. A significant change in prepayments of mortgages in the servicing portfolio could result in significant changes in the valuation adjustments, thus creating potential volatility in the carrying amount of residential MSRs. The Company compares fair value estimates and assumptions to observable market data where available, and also considers recent market activity and actual portfolio experience. The table below presents an analysis of residential MSRs under the fair value measurement method for the years ended December 31: 2022 2021 2020 (In millions) Carrying value, beginning of year $ 418 $ 296 $ 345 Additions 44 77 49 Purchases (1) 301 72 59 Increase (decrease) in fair value: Due to change in valuation inputs or assumptions 127 43 (89) Economic amortization associated with borrower repayments (2) (78) (70) (68) Carrying value, end of year $ 812 $ 418 $ 296 _________ (1) Purchases of residential MSRs can be structured with cash hold back provisions, therefore the timing of payment may be made in future periods. (2) Includes both total loan payoffs as well as partial paydowns. Regions' MSR decay methodology is a discounted net cash flow approach. Data and assumptions used in the fair value calculation, as well as the valuation’s sensitivity to rate fluctuations, related to residential MSRs (excluding related derivative instruments) as of December 31 are as follows: 2022 2021 (Dollars in millions) Unpaid principal balance $ 54,603 $ 36,769 Weighted-average CPR (%) 7.4 % 10.5 % Estimated impact on fair value of a 10% increase $ (50) $ (29) Estimated impact on fair value of a 20% increase $ (89) $ (52) Option-adjusted spread (basis points) 507 451 Estimated impact on fair value of a 10% increase $ (19) $ (8) Estimated impact on fair value of a 20% increase $ (37) $ (16) Weighted-average coupon interest rate 3.6 % 3.5 % Weighted-average remaining maturity (months) 308 295 Weighted-average servicing fee (basis points) 27.1 27.3 The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of an adverse variation in a particular assumption on the fair value of the residential MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. The derivative instruments utilized by Regions would serve to reduce the estimated impacts to fair value included in the table above. Servicing related fees, which include contractually specified servicing fees, late fees and other ancillary income resulting from the servicing of residential mortgage loans totaled $137 million, $102 million, and $95 million for the years ended December 31, 2022, 2021, and 2020, respectively. Residential mortgage loans are sold in the secondary market with standard representations and warranties regarding certain characteristics such as the quality of the loan, the absence of fraud, the eligibility of the loan for sale and the future servicing associated with the loan. Regions may be required to repurchase these loans at par, or make-whole or indemnify the purchasers for losses incurred when representations and warranties are breached. Regions maintains an immaterial repurchase liability related to residential mortgage loans sold with representations and warranty provisions. This repurchase liability is reported in other liabilities on the consolidated balance sheets and reflects management’s estimate of losses based on historical repurchase and loss trends, as well as other factors that may result in anticipated losses different from historical loss trends. Adjustments to this reserve are recorded in other non-interest expense on the consolidated statements of income. COMMERCIAL MORTGAGE BANKING ACTIVITIES Regions is an approved DUS lender. The DUS program provides liquidity to the multi-family housing market. In connection with the DUS program, Regions services commercial mortgage loans, retains commercial MSRs and intangible assets associated with the DUS license, and assumes a loss share guarantee associated with the loans. Regions' related DUS commercial MSRs are recorded in other assets at the lower of cost or estimated fair value and are amortized in proportion to, and over the estimated period that net servicing income is expected to be received based on projections of the amount and timing of estimated future net cash flows. See Note 1 for additional information. Also see Note 23 for additional information related to the guarantee. Regions' DUS portfolio totaled $81 million, $86 million, and $74 million at December 31, 2022, 2021 and 2020, respectively. Regions periodically evaluates DUS MSRs for impairment based on fair value. The estimated fair value of the DUS commercial MSRs was approximately $96 million at both December 31, 2022 and 2021 and $81 million at December 31, 2020. Servicing related fees in connection with the DUS program, which include contractually specified servicing fees, late fees and other ancillary income resulting from the servicing of DUS commercial mortgage loans totaled $24 million, $25 million, and $19 million for the years ended December 31, 2022, 2021, and 2020, respectively.

In performing the qualitative assessment, the Company evaluated events and circumstances since the last impairment analysis, recent operating performance including reporting unit performance, changes in market capitalization, regulatory actions and assessments, changes in the business climate, company-specific factors and trends in the banking industry. The results of the qualitative assessment indicated that it was more likely than not that the estimated fair value of each reporting unit exceeded its carrying amount as of the test date; therefore, the quantitative goodwill impairment tests were deemed unnecessary.

All issuances of these notes are, by definition, subordinated and subject in right of payment of both principal and interest to the prior payment in full of all senior indebtedness of the Company, which is generally defined as all indebtedness and other obligations of the Company to its creditors, except subordinated indebtedness. Payment of the principal of the notes may be accelerated only in the case of certain events involving bankruptcy, insolvency proceedings or reorganization of the Company. The subordinated notes described above qualify as Tier 2 capital under Federal Reserve guidelines, subject to diminishing credit as the respective maturity dates approach and subject to certain transition provisions. None of the subordinated notes are redeemable prior to maturity, unless there is an occurrence of a qualifying capital event. Regions and Regions Bank did not issue or redeem any debt in 2022. In the first quarter of 2021, Regions and Regions Bank redeemed senior notes due February 2021 and April 2021 in their entirety. In the third quarter of 2021, Regions issued $650 million of 1.80% senior notes due August 2028. Also in the third quarter of 2021, Regions redeemed senior notes due August 2023 in their entirety. In conjunction with the redemptions, Regions incurred related early extinguishment pre-tax charges totaling $20 million. Regions uses derivative instruments, primarily interest rate swaps, to manage interest rate risk by converting a portion of its fixed-rate debt to a variable-rate. The effective rate adjustments related to these hedges are included in interest expense on long-term borrowings. The weighted-average interest rate on total long-term debt, including the effect of derivative instruments, was 5.1 percent, 3.6 percent, and 2.7 percent for the years ended December 31, 2022, 2021 and 2020, respectively. Further discussion of derivative instruments is included in Note 20. The aggregate amount of contractual maturities of all long-term debt in each of the next five years and thereafter is as follows: Year Ended December 31 Regions Regions (In millions) 2023 $ — $ — 2024 100 — 2025 833 — 2026 — — 2027 — — Thereafter 853 498 $ 1,786 $ 498 Regions Bank maintains borrowing capacity at the FHLB and the FRB. Short and long-term funding from the FHLB and FRB are secured by pledged assets, primarily certain loan portfolios which are also subject to blanket lien arrangements with the FHLB and FRB. Borrowing capacity with the FHLB and FRB is contingent on the amount of collateral available to be pledged. At both December 31, 2022 and 2021 there were no outstanding borrowings with the FHLB or FRB. On February 24, 2022, Regions filed a shelf registration statement with the SEC. This shelf registration does not have a capacity limit and can be utilized by Regions to issue various debt and/or equity securities. The registration statement will expire in February 2025. Regions Bank may issue bank notes from time to time, either as part of a bank note program or as stand-alone issuances. Notes issued by Regions Bank may be senior or subordinated notes. Notes issued by Regions Bank are not deposits and are not insured or guaranteed by the FDIC. Regions may, from time to time, consider opportunistically retiring outstanding issued securities, including subordinated debt in privately negotiated or open market transactions. Regulatory approval would be required for retirement of some securities.

Regulatory Capital Requirements and Restrictions	Dec. 31, 2022
Banking and Thrift, Other Disclosure [Abstract]
Regulatory Capital Requirements and Restrictions	NOTE 12. REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS Regions and Regions Bank are required to comply with regulatory capital requirements established by Federal and State banking agencies. These regulatory capital requirements involve quantitative measures of the Company’s assets, liabilities and selected off-balance sheet items, and also qualitative judgments by the regulators. Failure to meet minimum capital requirements can subject the Company to a series of increasingly restrictive regulatory actions. Under the Basel III Rules, Regions is designated as a standardized approach bank. Regions is a "Category IV" institution under the FRB's rules for tailoring enhanced prudential standards. Banking regulations identify five capital categories: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. At December 31, 2022 and 2021, Regions and Regions Bank exceeded all current regulatory requirements, and were classified as "well-capitalized." Management believes that no events or changes have occurred subsequent to December 31, 2022 that would change this designation. Quantitative measures established by regulation to ensure capital adequacy require institutions to maintain minimum ratios of common equity Tier 1, Tier 1, and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to average tangible assets (the "Leverage" ratio). Federal banking agencies allowed a phase-in of the impact of CECL on regulatory capital. At December 31, 2021, the add-back to regulatory capital was calculated as the impact of initial adoption, adjusted for 25 percent of subsequent changes in the allowance. The amount is phased-in over a three-year period beginning in 2022. At December 31, 2022, the net impact of the add-back on CET1 was approximately $306 million, or approximately 24 basis points. The add-back amounts will decrease by approximately $100 million each year, or approximately 8 basis points, in the first quarters of 2023, 2024, and 2025. Regions participates in supervisory stress testing conducted by the Federal Reserve and its SCB is currently floored at 2.5 percent. See Note 14 "Shareholders' Equity and Accumulated Other Comprehensive Income (Loss)" to the consolidated financial statements for further details regarding CCAR results. The following tables summarize the applicable holding company and bank regulatory capital requirements: December 31, 2022 (1) Minimum Requirement Minimum Requirement plus SCB (2) To Be Well Amount Ratio (Dollars in millions) Common equity Tier 1 capital: Regions Financial Corporation $ 12,066 9.60 % 4.50 % 7.00 % N/A Regions Bank 13,509 10.77 4.50 7.00 6.50 % Tier 1 capital: Regions Financial Corporation $ 13,725 10.91 % 6.00 % 8.50 % 6.00 % Regions Bank 13,509 10.77 6.00 8.50 8.00 Total capital: Regions Financial Corporation $ 15,767 12.54 % 8.00 % 10.50 % 10.00 % Regions Bank 15,172 12.10 8.00 10.50 10.00 Leverage capital: Regions Financial Corporation $ 13,725 8.90 % 4.00 % 4.00 % N/A Regions Bank 13,509 8.80 4.00 4.00 5.00 % December 31, 2021 Minimum Requirement Minimum Requirement plus SCB (2) To Be Well Amount Ratio (Dollars in millions) Common equity Tier 1 capital: Regions Financial Corporation $ 10,844 9.57 % 4.50 % 7.00 % N/A Regions Bank 12,478 11.05 4.50 7.00 6.50 % Tier 1 capital: Regions Financial Corporation $ 12,503 11.03 % 6.00 % 8.50 % 6.00 % Regions Bank 12,478 11.05 6.00 8.50 8.00 Total capital: Regions Financial Corporation $ 14,441 12.74 % 8.00 % 10.50 % 10.00 % Regions Bank 13,985 12.38 8.00 10.50 10.00 Leverage capital: Regions Financial Corporation $ 12,503 8.08 % 4.00 % 4.00 % N/A Regions Bank 12,478 8.09 4.00 4.00 5.00 % _________ (1) The 2022 Basel III CET1 capital, Tier 1 capital, Total capital, and Leverage capital ratios are estimated. (2) Reflects Regions' SCB of 2.50%. SCB does not apply to leverage capital ratios. Substantially all net assets are owned by subsidiaries. The primary source of operating cash available to Regions is provided by dividends from subsidiaries. Statutory limits are placed on the amount of dividends the subsidiary bank can pay without prior regulatory approval. In addition, regulatory authorities require the maintenance of minimum capital-to-asset ratios at banking subsidiaries. Under the Federal Reserve’s Regulation H, Regions Bank may not, without approval of the Federal Reserve, declare or pay a dividend to Regions if the total of all dividends declared in a calendar year exceeds the total of (a) Regions Bank’s net income for that year and (b) its retained net income for the preceding two calendar years, less any required transfers to additional paid-in capital or to a fund for the retirement of preferred stock. Under Alabama law, Regions Bank may not pay a dividend to Regions in excess of 90 percent of its net earnings until the bank’s surplus is equal to at least 20 percent of capital. Regions Bank is also required by Alabama law to seek the approval of the Alabama Superintendent of Banking prior to paying a dividend to Regions if the total of all dividends declared by Regions Bank in any calendar year will exceed the total of (a) Regions Bank’s net earnings for that year, plus (b) its retained net earnings for the preceding two years, less any required transfers to surplus. The statute defines net earnings as “the remainder of all earnings from current operations plus actual recoveries on loans and investments and other assets, after deducting from the total thereof all current operating expenses, actual losses, accrued dividends on preferred stock, if any, and all federal, state and local taxes.” In addition to dividend restrictions, Federal statutes also prohibit unsecured loans from banking subsidiaries to the parent company. In addition, Regions must adhere to various HUD regulatory guidelines including required minimum capital to maintain their HUD approved status. Failure to comply with the HUD guidelines could result in withdrawal of this certification. As of December 31, 2022, Regions was in compliance with HUD guidelines. Regions is also subject to various capital requirements by secondary market investors.

(3) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to August 15, 2029, 5.700%, and (ii) for each period beginning on or after August 15, 2029, three-month LIBOR plus 3.148%. (4) Dividends, if declared, will be paid quarterly at an annual rate equal to (i) for each period beginning prior to September 15, 2025, 5.750%, and (ii) for each period beginning on or after September 15, 2025, the five-year treasury rate as of the most recent reset dividend determination date plus 5.426%. All series of preferred stock have no stated maturity and redemption is solely at Regions' option, subject to regulatory approval, in whole, or in part, after the earliest redemption date or in whole, but not in part, at any time following a regulatory capital treatment event for the Series B, Series C, Series D, and Series E preferred stock. The Board of Directors declared a total of $81 million in cash dividends on Series B, and Series C and Series D Preferred Stock during both 2022 and 2021. The Board declared $18 million and $11 million in cash dividends on Series E preferred stock during 2022 and 2021, respectively; the initial quarterly dividend for Series E was declared in the third quarter of 2021. Additionally, total cash dividends for 2021 includes $16 million in cash dividends on Series A preferred stock, which were fully redeemed during the second quarter of 2021. In total the Board of Directors declared $99 million and $108 million in cash dividends on preferred stock in 2022 and 2021, respectively. In the event Series B, Series C, Series D or Series E preferred shares are redeemed at the liquidation amounts, $67 million, $10 million, $4 million, or $10 million in excess of the redemption amount over the carrying amount will be recognized, respectively. Approximately $52 million of Series B preferred dividends that were recorded as a reduction of preferred stock, including related surplus, will be recorded as a reduction to common shareholders' equity. The remaining amounts listed represent issuance costs that were recorded as reductions to preferred stock, including related surplus, and will be recorded as reductions to net income available to common shareholders. COMMON STOCK As a result of Regions' voluntary participation in 2021 CCAR, effective October 1, 2021, Regions' SCB requirement for the fourth quarter of 2021 through the third quarter of 2022 was floored at 2.5 percent. Regions' 2022 stress testing results from the FRB reflected that the Company exceeded all minimum capital levels and the SCB will continue to be floored at 2.5 percent for the fourth quarter of 2022 through the third quarter of 2023. On April 20, 2022, the Board authorized the repurchase of up to $2.5 billion of the Company's common stock, permitting purchases from the second quarter of 2022 through the fourth quarter of 2024. As of December 31, 2022, Regions had repurchased approximately 725 thousand shares of common stock at a total cost of $15 million under this plan. All of these shares were immediately retired upon repurchase and therefore were not included in treasury stock. Prior to the new common stock repurchase plan, the Board authorized the repurchase of up to $2.5 billion of the Company's common stock, permitting purchases from the second quarter of 2021 through the first quarter of 2022. During the year ended December 31, 2021, Regions repurchased approximately 20.8 million shares of common stock under this plan which reduced shareholder's equity by $467 million. Included in these share repurchases were approximately 1.0 million shares that were repurchased as part of the amendment to the Company’s deferred investment plan for its directors. During the three months ended March 31, 2022, Regions repurchased an additional 9.1 million shares at a total cost of $215 million under this plan and concluded the plan in the first quarter of 2022. Regions declared $0.74 per share in cash dividends for 2022, $0.65 for 2021, and $0.62 for 2020.

Share-Based Payment Arrangement [Abstract]
Share-Based Payments	Regions administers long-term incentive compensation plans that permit the granting of incentive awards in the form of restricted stock awards, performance awards, stock options and stock appreciation rights. While Regions has the ability to issue stock appreciation rights, none has been issued to date. The terms of all awards issued under these plans are determined by the CHR Committee of the Board; however, no awards may be granted after the tenth anniversary from the date the plans were initially approved by shareholders. Incentive awards usually vest based on employee service, generally within three years from the date of the grant. The contractual lives of options, issued in periods prior to 2021, granted under these plans were typically ten years from the date of the grant. On April 23, 2015, the shareholders of the Company approved the Regions Financial Corporation 2015 LTIP, which permits the Company to grant to employees and directors various forms of incentive compensation. These forms of incentive compensation are similar to the types of compensation approved in prior plans. The 2015 LTIP authorizes 60 million common share equivalents available for grant, where grants of options and grants of full value awards (e.g., shares of restricted stock, restricted stock units and performance stock units) count as one share equivalent. Unless otherwise determined by the CHR Committee of the Board, grants of restricted stock, restricted stock units, and performance stock units accrue dividends, or their notional equivalent, as they are declared by the Board, and are paid upon vesting of the award. Upon adoption of the 2015 LTIP, Regions closed the prior long-term incentive plan to new grants, and, accordingly, prospective grants must be made under the 2015 LTIP or a successor plan. All existing grants under prior long-term incentive plans are unaffected by adoption of the 2015 LTIP. The number of remaining share equivalents available for future issuance under the 2015 LTIP was approximately 28 million at December 31, 2022. Grants of performance-based restricted stock typically have a three-year performance period, and shares vest within three years after the grant date. Restricted stock units typically vest over three years. Grantees of restricted stock awards or units must either remain employed with the Company for certain periods from the date of grant in order for shares to be released or issued or retire after meeting the standards of a retiree, at which time shares would be issued and released. The terms of these plans generally stipulate that the exercise price of options may not be less than the fair market value of Regions' common stock at the date the options are granted. Regions issues new shares from authorized reserves upon exercise. The following table summarizes the elements of compensation cost recognized in the consolidated statements of income for the years ended December 31: 2022 2021 2020 (In millions) Compensation cost of share-based compensation awards: Restricted and performance stock awards $ 60 $ 57 $ 53 Tax benefits related to share-based compensation cost (15) (14) (13) Compensation cost of share-based compensation awards, net of tax $ 45 $ 43 $ 40 RESTRICTED STOCK AWARDS AND PERFORMANCE STOCK AWARDS During 2022, 2021 and 2020, Regions made restricted stock grants that vest upon satisfaction of service conditions and restricted stock award and performance stock award grants that vest based upon service conditions and performance conditions. Incremental shares earned above the performance target associated with previous performance stock awards are included when and if performance targets are achieved. Dividend payments during the vesting period are deferred to the end of the vesting term. The fair value of these restricted shares, restricted stock units and performance stock units was estimated based upon the fair value of the underlying shares on the date of the grant. The valuation was not adjusted for the deferral of dividends. Activity related to restricted stock awards and performance stock awards for 2022, 2021 and 2020 is summarized as follows: Number of Weighted-Average Non-vested at December 31, 2019 8,997,358 $ 15.62 Granted 6,466,526 8.46 Vested (3,314,572) 14.60 Forfeited (467,152) 11.86 Non-vested at December 31, 2020 11,682,160 $ 12.14 Granted 2,984,065 21.18 Vested (3,227,513) 15.91 Forfeited (231,818) 13.24 Non-vested at December 31, 2021 11,206,894 $ 13.39 Granted 2,831,304 21.39 Vested (3,543,152) 14.24 Forfeited (331,283) 14.73 Non-vested at December 31, 2022 10,163,763 $ 15.23 As of December 31, 2022, the pre-tax amount of non-vested restricted stock, restricted stock units and performance stock units not yet recognized was $60 million, which will be recognized over a weighted-average period of 1.71 years. The total fair value of shares vested during the years ended December 31, 2022, 2021, and 2020, was $76 million, $75 million, and $35 million, respectively. No share-based compensation costs were capitalized during the years ended December 31, 2022, 2021, or 2020.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
Employee Benefit Plans	PENSION AND OTHER POSTRETIREMENT BENEFITS Regions' defined benefit pension plans cover only certain employees as the pension plans are closed to new entrants. Benefits under the pension plans are based on years of service and the employee’s highest five consecutive years of compensation during the last ten years of employment. Regions’ funding policy is to contribute annually at least the amount required by IRS minimum funding standards. Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. The Company also sponsors a SERP, which is a non-qualified pension plan that provides certain senior executive officers defined benefits in relation to their compensation. Actuarially determined pension expense is charged to current operations using the projected unit credit method. All defined benefit plans are referred to as “the plans” throughout the remainder of this footnote. The following table sets forth the plans’ change in benefit obligation, plan assets and funded status, using a December 31 measurement date, and amounts recognized in the consolidated balance sheets at December 31: Qualified Plans Non-qualified Plans Total 2022 2021 2022 2021 2022 2021 (In millions) Change in benefit obligation Projected benefit obligation, beginning of year $ 2,281 $ 2,435 $ 156 $ 188 $ 2,437 $ 2,623 Service cost 34 38 2 3 36 41 Interest cost 56 49 3 2 59 51 Actuarial (gains) losses (568) (73) (17) — (585) (73) Benefit payments (108) (165) (8) (8) (116) (173) Administrative expenses (3) (3) — — (3) (3) Plan settlements (69) — (9) (29) (78) (29) Projected benefit obligation, end of year $ 1,623 $ 2,281 $ 127 $ 156 $ 1,750 $ 2,437 Change in plan assets Fair value of plan assets, beginning of year $ 2,554 $ 2,469 $ — $ — $ 2,554 $ 2,469 Actual return on plan assets (404) 253 — — (404) 253 Company contributions — — 17 37 17 37 Benefit payments (108) (165) (8) (8) (116) (173) Administrative expenses (3) (3) — — (3) (3) Plan settlements (69) — (9) (29) (78) (29) Fair value of plan assets, end of year $ 1,970 $ 2,554 $ — $ — $ 1,970 $ 2,554 Funded status and accrued benefit (cost) at measurement date $ 347 $ 273 $ (127) $ (156) $ 220 $ 117 Amount recognized in the Consolidated Balance Sheets: Other assets $ 347 $ 273 $ — $ — $ 347 $ 273 Other liabilities — — (127) (156) (127) (156) $ 347 $ 273 $ (127) $ (156) $ 220 $ 117 Pre-tax amounts recognized in Accumulated Other Comprehensive (Income) Loss: Net actuarial loss $ 537 $ 590 $ 36 $ 62 $ 573 $ 652 The accumulated benefit obligation for the qualified plans was $1.5 billion and $2.1 billion as of December 31, 2022 and 2021, respectively. Total plan assets exceeded the corresponding accumulated benefit obligation for the qualified plans as of December 31, 2022 and 2021. The accumulated benefit obligation for the non-qualified plans was $127 million and $155 million as of December 31, 2022 and 2021, respectively, which exceeded all corresponding plan assets for each period. As of December 31, 2022 and 2021, the actuarial (gains) losses related to the change in the benefit obligation were primarily driven by changes in the discount rate. Net periodic pension cost (benefit) included the following components for the years ended December 31: Qualified Plans Non-qualified Plans Total 2022 2021 2020 2022 2021 2020 2022 2021 2020 (In millions) Service cost $ 34 $ 38 $ 34 $ 2 $ 3 $ 5 $ 36 $ 41 $ 39 Interest cost 56 49 64 3 2 4 59 51 68 Expected return on plan assets (139) (142) (148) — — — (139) (142) (148) Amortization of actuarial loss 25 46 39 7 8 8 32 54 47 Settlement charge 4 — — 2 11 — 6 11 — Net periodic pension (benefit) cost $ (20) $ (9) $ (11) $ 14 $ 24 $ 17 $ (6) $ 15 $ 6 The service cost component of net periodic pension (benefit) cost is recorded in salaries and employee benefits on the consolidated statements of income. Components other than service cost are recorded in other non-interest expense on the consolidated statements of income. The assumptions used to determine benefit obligations at December 31 are as follows: Qualified Plans Non-qualified Plans 2022 2021 2022 2021 Discount rate 5.42 % 2.85 % 5.38 % 2.64 % Rate of annual compensation increase 4.00 % 4.00 % 3.00 % 3.00 % The weighted-average assumptions used to determine net periodic pension (benefit) cost for the years ended December 31 are as follows: Qualified Plans Non-qualified Plans 2022 2021 2020 2022 2021 2020 Discount rate 2.85 % 2.48 % 3.37 % 2.72 % 2.20 % 3.00 % Expected long-term rate of return on plan assets 5.62 % 5.87 % 6.65 % N/A N/A N/A Rate of annual compensation increase 4.00 % 4.00 % 4.00 % 3.00 % 3.00 % 3.00 % Regions utilizes a disaggregated approach in the estimation of the service and interest components of net periodic pension costs by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This provides a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows and the corresponding spot yield curve rates. The expected long-term rate of return on the qualified plans' assets is based on an estimated reasonable range of probable returns. The assumption is established by considering historical and anticipated returns of the asset classes invested in by the qualified plans and the allocation strategy currently in place among those classes. Management chose a point within the range based on the probability of achievement combined with incremental returns attributable to active management. For 2023, the weighted- average expected long-term rate of return on plan assets is 6.37 percent, using the weighted fair value of plan assets as of December 31, 2022. The qualified plans' investment strategy is continuing to shift from focusing on maximizing asset returns to minimizing funding ratio volatility, with a planned increase in the allocation to fixed income securities. The combined target asset allocation is 35 percent equities, 59 percent fixed income securities and 6 percent in all other types of investments. Equity securities include investments in large and small/mid cap companies primarily located in the U.S., international equities, and private equities. Fixed income securities include investments in corporate and government bonds, asset-backed securities and any other fixed income investments as allowed by respective prospectuses and other offering documents. Other types of investments may include hedge funds and real estate funds that follow several different strategies. The plans' assets are highly diversified with respect to asset class, security and manager. Investment risk is controlled with the plans' assets rebalancing to target allocations on a periodic basis and continual monitoring of investment managers’ performance relative to the investment guidelines established with each investment manager. Regions’ qualified plans have a portion of their investments in Regions' common stock. At December 31, 2022, the plans held 2,855,618 shares, which represents a total market value of approximately $62 million, or approximately 3 percent of the plans' assets. The following table presents the fair value of Regions’ qualified pension plans’ financial assets as of December 31: 2022 2021 Level 1 Level 2 Level 3 Fair Value Level 1 Level 2 Level 3 Fair Value (In millions) Cash and cash equivalents $ 34 $ — $ — $ 34 $ 116 $ — $ — $ 116 Fixed income securities: U.S. Treasury securities $ 280 $ — $ — $ 280 $ 346 $ — $ — $ 346 Federal agency securities — 15 — 15 — 36 — 36 Corporate bonds and other debt — 354 — 354 — 509 — 509 Total fixed income securities $ 280 $ 369 $ — $ 649 $ 346 $ 545 $ — $ 891 Equity securities: Domestic $ 135 $ — $ — $ 135 $ 146 $ — $ — $ 146 International 130 — — 130 142 — — 142 Total equity securities $ 265 $ — $ — $ 265 $ 288 $ — $ — $ 288 International mutual funds $ 125 $ — $ — $ 125 $ 148 $ — $ — $ 148 Total assets in the fair value hierarchy $ 704 $ 369 $ — $ 1,073 $ 898 $ 545 $ — $ 1,443 Collective trust funds: Fixed income fund (1) $ 340 $ 468 Common stock fund (1) 168 204 International fund (1) 40 45 Total collective trust funds $ 548 $ 717 Real estate funds measured at NAV (1) $ 177 $ 167 Private equity funds measured at NAV (1) $ 172 $ 227 $ 1,970 $ 2,554 __________ (1) In accordance with accounting guidance, investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient are not required to be classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of amounts reported in the fair value hierarchy to amounts reported on the balance sheet. For all investments, the plans attempt to use quoted market prices of identical assets on active exchanges, or Level 1 measurements. Where such quoted market prices are not available, the plans typically employ quoted market prices of similar instruments (including matrix pricing) and/or discounted cash flows to estimate a value of these securities, or Level 2 measurements. Level 2 discounted cash flow analyses are typically based on market interest rates, prepayment speeds and/or option adjusted spreads. Investments held in the plans consist of cash and cash equivalents, fixed income securities, equity securities, collective trust funds, hedge funds, real estate funds, private equity and other assets and are recorded at fair value on a recurring basis. See Note 1 for a description of valuation methodologies related to U.S. Treasuries, federal agency securities, and equity securities. The methodology described in Note 1 for other debt securities is applicable to corporate bonds and other debt. Mutual funds are valued based on quoted market prices of identical assets on active exchanges; these valuations are Level 1 measurements. Collective trust funds, hedge funds, real estate funds, private equity funds and other assets are valued based on net asset value or the valuation of the limited partner’s portion of the equity of the fund. Third party fund managers provide these valuations based primarily on estimated valuations of underlying investments. Information about the expected cash flows for the qualified and non-qualified plans is as follows: Qualified Plans Non-qualified Plans (In millions) Expected Employer Contributions: 2023 $ — $ 43 Expected Benefit Payments: 2023 $ 125 $ 43 2024 127 9 2025 126 10 2026 127 10 2027 126 10 Next five years 601 44 OTHER PLANS Regions has a defined-contribution 401(k) plan that includes a Company match of eligible employee contributions. Eligible employees include those who have been employed for one year and have worked a minimum of 1,000 hours. The Company match is invested based on the employees' allocation elections. Regions provides an automatic 2 percent cash 401(k) contribution to eligible employees regardless of whether or not they are contributing to the 401(k) plan. To receive this contribution, employees must be employed at the end of the year and not actively accruing a benefit in the Regions’ pension plans. Regions’ cash contribution was approximately $22 million for 2022 and 2021 and $19 million for 2020. For 2022, 2021 and 2020, eligible employees who were already contributing to the 401(k) plan received up to a 5 percent Company match plus the automatic 2 percent cash contribution. Regions’ match to the 401(k) plan on behalf of employees totaled $67 million in 2022, $63 million in 2021, and $62 million in 2020. Regions’ 401(k) plan held 16 million shares and 17 million shares of Regions' common stock at December 31, 2022 and 2021, respectively. The 401(k) plan received approximately $12 million, $11 million and $12 million in dividends on Regions' common stock for the years ended December 31, 2022, 2021 and 2020, respectively.

Accordingly, a valuation allowance has been established in the amount of $21 million against such benefits at December 31, 2022 compared to $29 million at December 31, 2021. A reconciliation of the beginning and ending amount of UTB is as follows: 2022 2021 2020 (In millions) Balance at beginning of year $ 9 $ 12 $ 37 Additions based on tax positions taken in a prior period — — 2 Reductions based on tax positions taken in a prior period — — (25) Settlements — (2) (1) Expiration of statute of limitations (1) (1) (1) Balance at end of year $ 8 $ 9 $ 12 The Company files U.S. federal, state, and local income tax returns. The Company is in the IRS’s Compliance Assurance Process program and examinations of the U.S federal consolidated income tax return for tax years through 2020 have been completed. With some exceptions for non-footprint states, the Company is no longer subject to state and local tax examinations for tax years prior to 2018. Currently, there are no material disputed tax positions with federal or state taxing authorities. Accordingly, the Company does not anticipate that any adjustments relating to federal or state tax examinations will result in material changes to its business, financial position, results of operations or cash flows. There are no expected decreases to the potential liability for UTBs during the next twelve months due to completion of tax authority examinations and/or expirations of statutes of limitations. As of December 31, 2022, 2021 and 2020, the balances of the Company’s UTBs that would reduce the effective tax rates, if recognized, were $8 million, $7 million and $9 million, respectively.

Includes accrued interest as applicable. (2) Netting adjustments represent amounts recorded to convert derivative assets and derivative liabilities from a gross basis to a net basis in accordance with applicable accounting guidance. The net basis takes into account the impact of cash collateral received or posted, legally enforceable master netting agreements, and variation margin that allow Regions to settle derivative contracts with the counterparty on a net basis and to offset the net position with the related cash collateral. HEDGING DERIVATIVES Derivatives entered into to manage interest rate risk and facilitate asset/liability management strategies are designated as hedging derivatives. Derivative financial instruments that qualify in a hedging relationship are classified, based on the exposure being hedged, as either fair value hedges or cash flow hedges. Additional information regarding accounting policies for derivatives is described in Note 1. FAIR VALUE HEDGES Fair value hedge relationships mitigate exposure to the change in fair value of an asset, liability or firm commitment. Regions enters into interest rate swap agreements to manage interest rate exposure on the Company’s fixed-rate borrowings. These agreements involve the receipt of fixed-rate amounts in exchange for floating-rate interest payments over the life of the agreements. Regions also enters into interest rate swap agreements to manage interest rate exposure on certain of the Company's fixed-rate prepayable and non-prepayable debt securities available for sale. These agreements involve the payment of fixed-rate amounts in exchange for floating-rate interest receipts. CASH FLOW HEDGES Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. Regions enters into interest rate swap, floors, and agreements with a combination of these instruments to manage overall cash flow changes related to interest rate risk exposure on variable rate loans. The agreements effectively modify the Company’s exposure to interest rate risk by utilizing receive fixed/pay LIBOR or SOFR interest rate swaps and interest rate floors. As of December 31, 2022, Regions is hedging its exposure to the variability in future cash flows through 2029. The balance of terminated cash flow hedges in AOCI will be amortized into earnings through 2026. The following table presents the pre-tax impact of terminated cash flow hedges on AOCI for the twelve months ended December 31: 2022 2021 (In millions) Unrealized gains on terminated hedges included in AOCI - beginning of period $ 700 $ 121 Unrealized gains (losses) on terminated hedges arising during the period (291) 739 Reclassification adjustments for amortization of unrealized (gains) on terminated hedges into net income (245) (160) Unrealized gains on terminated hedges included in AOCI - end of period $ 164 $ 700 Regions expects to reclassify into earnings approximately $191 million in pre-tax expenses due to the net receipt/ payment of interest and amortization on all cash flow hedges within the next twelve months. Included in this amount is $54 million in pre-tax net gains related to the amortization of terminated cash flow hedges.

(2) Pre-tax The following tables present the carrying amount and associated cumulative basis adjustment related to the application of hedge accounting that is included in the carrying amount of hedged assets and liabilities in fair value hedging relationships as of December 31: 2022 2021 Hedged Items Currently Designated Hedged Items Currently Designated Carrying Amount of Assets/(Liabilities) Hedge Accounting Basis Adjustment Carrying Amount of Assets/(Liabilities) Hedge Accounting Basis Adjustment (In millions) (In millions) Debt securities available for sale (1)(2) $ 23 $ — $ 9,901 $ — Long-term borrowings (1,239) 158 (1,363) 34 _____ (1) As of December 31, 2021, the Company designated interest rate swaps as fair value hedges of debt securities available for sale under the portfolio layer method under which the Company designated $5.8 billion as the hedged amount from a closed portfolio of prepayable financial assets with a carrying amount of $9.1 billion. (2) Carrying amount represents amortized cost. DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS The Company holds a portfolio of interest rate swaps, option contracts, and futures and forward commitments that result from transactions with its commercial customers in which they manage their risks by entering into a derivative with Regions. The Company monitors and manages the net risk in this customer portfolio and enters into separate derivative contracts in order to reduce the overall exposure to pre-defined limits. For both derivatives with its end customers and derivatives Regions enters into to mitigate the risk in this portfolio, the Company is subject to market risk and the risk that the counterparty will default. The contracts in this portfolio are not designated as accounting hedges and are marked-to market through earnings (in capital markets income) and included in other assets and other liabilities, as appropriate. Regions enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. At December 31, 2022 and 2021, Regions had $118 million and $419 million, respectively, in total notional amount of interest rate lock commitments. Regions manages market risk on interest rate lock commitments and mortgage loans held for sale with corresponding forward sale commitments. Residential mortgage loans held for sale are recorded at fair value with changes in fair value recorded in mortgage income. Commercial mortgage loans held for sale are recorded at either the lower of cost or market or at fair value based on management's election. At December 31, 2022 and 2021, Regions had $233 million and $987 million, respectively, in total notional amounts related to these forward sale commitments. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to residential mortgage loans are included in mortgage income. Changes in mark-to-market from both interest rate lock commitments and corresponding forward sale commitments related to commercial mortgage loans are included in capital markets income. Regions has elected to account for residential MSRs at fair value with any changes to fair value recorded in mortgage income. Concurrent with the election to use the fair value measurement method, Regions began using various derivative instruments in the form of forward rate commitments, futures contracts, swaps and swaptions to mitigate the effect of changes in the fair value of its residential MSRs in its consolidated statements of income. As of December 31, 2022 and 2021, the total notional amount related to these contracts was $3.4 billion and $4.5 billion, respectively. The following table presents the location and amount of gain or (loss) recognized in income on derivatives not designated as hedging instruments for the years ended December 31: Derivatives Not Designated as Hedging Instruments 2022 2021 2020 (In millions) Capital markets income: Interest rate swaps $ 108 $ 46 $ 21 Interest rate options 23 28 36 Interest rate futures and forward commitments 10 15 14 Other contracts 11 4 1 Total capital markets income 152 93 72 Mortgage income: Interest rate swaps (118) (45) 83 Interest rate options (14) (32) 30 Interest rate futures and forward commitments (4) 13 (2) Total mortgage income (136) (64) 111 $ 16 $ 29 $ 183 CREDIT DERIVATIVES Regions has both bought and sold credit protection in the form of participations on interest rate swaps (swap participations). These swap participations, which meet the definition of credit derivatives, were entered into in the ordinary course of business to serve the credit needs of customers. Swap participations, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if the customer fails to make payment on any amounts due to Regions upon early termination of the swap transaction and have maturities between 2023 and 2029. Swap participations, whereby Regions has sold credit protection have maturities between 2023 and 2038. For contracts where Regions sold credit protection, Regions would be required to make payment to the counterparty if the customer fails to make payment on any amounts due to the counterparty upon early termination of the swap transaction. Regions bases the current status of the prepayment/performance risk on bought and sold credit derivatives on recently issued internal risk ratings consistent with the risk management practices of unfunded commitments. Regions’ maximum potential amount of future payments under these contracts as of December 31, 2022 was approximately $482 million. This scenario occurs if variable interest rates were at zero percent and all counterparties defaulted with zero recovery. The fair value of sold protection at December 31, 2022 and 2021 was immaterial. In transactions where Regions has sold credit protection, recourse to collateral associated with the original swap transaction is available to offset some or all of Regions’ obligation. Regions has bought credit protection in the form of credit default indices. These indices, which meet the definition of credit derivatives, were entered into in the ordinary course of business to economically hedge credit spread risk in commercial mortgage loans held for sale whereby the fair value option has been elected. Credit derivatives, whereby Regions has purchased credit protection, entitle Regions to receive a payment from the counterparty if losses on the underlying index exceed a certain threshold, dependent upon the tranche rating of the capital structure. CONTINGENT FEATURES Certain of Regions’ derivative instrument contracts with broker-dealers contain credit-related termination provisions and/or credit related provisions regarding the posting of collateral, allowing those broker-dealers to terminate the contracts in the event that Regions’ and/or Regions Bank’s credit ratings falls below specified ratings from certain major credit rating agencies. The aggregate fair values of all derivative instruments with any credit-risk-related contingent features that were in a liability position on December 31, 2022 and 2021, were $17 million and $81 million, respectively, for which Regions had posted collateral of $20 million and $84 million, respectively, in the normal course of business.

Fair Value Disclosures [Abstract]
Fair Value Measurements	See Note 1 for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis. Assets and liabilities measured at fair value rarely transfer between Level 1 and Level 2 measurements. Marketable equity securities and debt securities available for sale may be periodically transferred to or from Level 3 valuation based on management’s conclusion regarding the observability of inputs used in valuing the securities. Such transfers are accounted for as if they occur at the beginning of a reporting period.

(2) As permitted under U.S. GAAP, variation margin collateral payments made or received for derivatives that are centrally cleared are legally characterized as settled. As such, these derivative assets and derivative liabilities and the related variation margin collateral are presented on a net basis on the balance sheet. Assets and liabilities in all levels could result in volatile and material price fluctuations. Realized and unrealized gains and losses on Level 3 assets represent only a portion of the risk to market fluctuations in Regions’ consolidated balance sheets. Further, derivatives included in Levels 2 and 3 are used by ALCO in a holistic approach to managing price fluctuation risks. The following tables present an analysis for residential MSRs for the years ended December 31, 2022, 2021 and 2020, respectively. An analysis of commercial mortgage loans held for sale, that were acquired in the fourth quarter of 2021, is also presented for the years ended December 31, 2022 and December 31, 2021.

RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Residential mortgage servicing rights The significant unobservable inputs used in the fair value measurement of residential MSRs are OAS and CPR. This valuation requires generating cash f low projections over multiple interest rate scenarios and discounting those cash flows at a risk-adjusted rate. Additionally, the impact of prepayments and changes in the OAS are based on a variety of underlying inputs including servicing costs. Increases or decreases to the underlying cash flow inputs will have a corresponding impact on the value of the MSR asset. The net change in unrealized gains (losses) included in earnings related to MSRs held at period end are disclosed as the changes in valuation inputs or assumptions included in the MSR rollforward table in Note 6. Commercial mortgage loans held for sal e The significant unobservable inputs used in the fair value measurement of commercial mortgage loans held for sale are credit spreads for bonds in commercial mortgage-backed securitization. Commercial mortgage loans held for sale are valued based on traded market prices for comparable commercial mortgage-backed securitizations, into which the loans will be placed, adjusted for movements of interest rates and credit spreads. Increases or decreases in credit spreads would result in an inverse impact to fair value. The following tables present detailed information regarding material assets and liabilities measured at fair value using significant unobservable inputs (Level 3) as of December 31, 2022, 2021 and 2020. The tables include the valuation techniques and the significant unobservable inputs utilized. The range of each significant unobservable input as well as the weighted-average within the range utilized at December 31, 2022, 2021 and 2020 are included. Following the tables are descriptions of the valuation techniques and the sensitivity of the techniques to changes in the significant unobservable inputs.

FAIR VALUE OPTION As discussed above, the Company elected the option to measure certain commercial mortgage loans held for sale at fair value. At December 31, 2022, the balance of these loans was immaterial. At December 31, 2021, commercial mortgage loans held for sale at fair value had both an aggregate fair value and unpaid principal balance of $90 million. The Company has elected the option to measure certain commercial and industrial loans held for sale at fair value, as these loans are actively traded in the secondary market. The Company is able to obtain fair value estimates for substantially all of these loans through a third party valuation service that is broadly used by market participants. While most of the loans are traded in the market, the volume and level of trading activity is subject to variability and the loans are not exchange-traded. The balance of these loans held for sale was immaterial at December 31, 2022 and December 31, 2021. Regions has elected the fair value option for all eligible agency residential first mortgage loans originated with the intent to sell. This election allows for a more effective offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting. Fair values of residential first mortgage loans held for sale are based on traded market prices of similar assets where available and/or discounted cash flows at market interest rates, adjusted for securitization activities that include servicing values and market conditions, and are recorded in loans held for sale. The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for mortgage loans held for sale measured at fair value at December 31: 2022 2021 Aggregate Aggregate Aggregate Fair Aggregate Aggregate Aggregate Fair (In millions) Residential mortgage loans held for sale, at fair value $ 160 $ 157 $ 3 $ 680 $ 659 $ 21 Interest income on mortgage loans held for sale is recognized based on contractual rates and is reflected in interest income on loans held for sale. The following table details net gains and losses resulting from changes in fair value of residential mortgage loans held for sale, which were recorded in mortgage income in the consolidated statements of income for the years presented. These changes in fair value are mostly offset by economic hedging activities. An immaterial portion of these amounts was attributable to changes in instrument-specific credit risk. 2022 2021 (In millions) Net gains (losses) resulting from changes in fair value of residential mortgage loans held for sale $ (17) $ (56) NON-RECURRING FAIR VALUE MEASUREMENTS Items measured at fair value on a non-recurring basis include loans held for sale for which the fair value option has not been elected, foreclosed property and other real estate and equity investments without a readily determinable fair value; all of which may be considered either Level 2 or Level 3 valuation measurements. Non-recurring fair value adjustments related to loans held for sale and foreclosed property and other real estate are typically a result of the application of lower of cost or fair value accounting during the period. Non-recurring fair value adjustments related to equity investments without readily determinable fair values are the result of impairments or price changes from observable transactions. The balances of each of these assets, as well as the related fair value adjustments during the periods, were immaterial at both December 31, 2022 and 2021. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of December 31, 2022 are as follows: 2022 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 11,227 $ 11,227 $ 11,227 $ — $ — Debt securities held to maturity 801 751 — 751 — Debt securities available for sale 27,933 27,933 1,187 26,744 2 Loans held for sale 354 354 — 335 19 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 94,044 89,540 — — 89,540 Other earning assets 1,308 1,308 529 779 — Derivative assets 2,609 2,609 3 2,603 3 Financial liabilities: Derivative liabilities 3,378 3,378 2 3,375 1 Deposits (4) 131,743 131,668 — 131,668 — Long-term borrowings 2,284 2,376 — 2,375 1 Loan commitments and letters of credit 153 153 — — 153 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at December 31, 2022 was $4.5 billion or 4.8 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.5 billion at December 31, 2022. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, money market accounts and certain other time deposit accounts is the amount payable on demand at the reporting date (i.e., the carrying amount). Fair values for certificates of deposit are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company's financial instruments as of December 31, 2021 are as follows: 2021 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 29,411 $ 29,411 $ 29,411 $ — $ — Debt securities held to maturity 899 950 — 950 — Debt securities available for sale 28,481 28,481 1,132 27,347 2 Loans held for sale 1,003 1,003 — 899 104 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 84,866 85,086 — — 85,086 Other earning assets (4) 1,104 1,104 464 640 — Derivative assets 1,111 1,111 — 1,098 13 Financial liabilities: Derivative liabilities 1,012 1,012 — 1,009 3 Deposits (5) 139,072 139,101 — 139,101 — Long-term borrowings 2,407 2,847 — 2,845 2 Loan commitments and letters of credit 123 123 — — 123 _________ (1) Estimated fair values are consistent with an exit price concept.

In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value premium on the loan portfolio's net carrying amount at December 31, 2021 was $220 million or 0.3 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.4 billion at December 31, 2021. (4) Excluded from this table is the operating lease carrying amount of $83 million at December 31, 2021.

Segment Reporting [Abstract]
Business Segment Information	Each of Regions’ reportable segments is a strategic business unit that serves specific needs of Regions’ customers based on the products and services provided. The segments are based on the manner in which management views the financial performance of the business. The Company has three reportable segments: Corporate Bank, Consumer Bank, and Wealth Management, with the remainder in Other. The application and development of management reporting methodologies is a dynamic process and is subject to periodic enhancements. As these enhancements are made, financial results presented by each reportable segment may be periodically revised. Accordingly, the prior periods were updated to reflect these enhancements. In the first quarter of 2021, the net interest income allocation methodology was enhanced. All net interest income including the FTP offset, activities of the treasury function, securities portfolio and interest rate risk activities is allocated to the three reporting segments. The Corporate Bank segment represents the Company’s commercial banking functions including commercial and industrial, commercial real estate and investor real estate lending. This segment also includes equipment lease financing, as well as capital markets activities, which include securities underwriting and placement, loan syndication and placement, foreign exchange, derivatives, merger and acquisition and other advisory services. Corporate Bank customers include corporate, middle market, and commercial real estate developers and investors. Corresponding deposit products related to these types of customers are also included in this segment. The Consumer Bank segment represents the Company’s branch network, including consumer banking products and services related to residential first mortgages, home equity lines and loans, consumer credit cards and other consumer loans, as well as the corresponding deposit relationships. These services are also provided through the Company's digital channels and contact center. The Wealth Management segment offers individuals, businesses, governmental institutions and non-profit entities a wide range of solutions to help protect, grow and transfer wealth. Offerings include credit related products, trust and investment management, asset management, retirement and savings solutions and estate planning. Other includes the Company’s Treasury function, the securities portfolio, wholesale funding activities, interest rate risk management activities and other corporate functions that are not related to a strategic business unit. Also within Other are certain reconciling items in order to translate the segment results that are based on management accounting practices into consolidated results. Management accounting practices utilized by Regions as the basis of presentation for segment results include the following: • Net interest income is presented based upon an FTP approach, for which market-based funding charges/credits are assigned within the segments. By allocating a cost or a credit to each product based on the FTP framework, management is able to more effectively measure the net interest margin contribution of its assets/liabilities by segment. The summation of the interest income/expense and FTP charges/credits for each segment is its designated net interest income. • Provision for (benefit from) credit losses is allocated to each segment based on an estimated loss methodology. The difference between the consolidated provision for (benefit from) credit losses and the segments’ estimated loss is reflected in Other. • Income tax expense (benefit) is calculated for the Corporate Bank, Consumer Bank and Wealth Management based on a consistent federal and state statutory rate. Any difference between the Company’s consolidated income tax expense (benefit) and the segments’ calculated amounts is reflected in Other. • Management reporting allocations of certain expenses are made in order to analyze the financial performance of the segments. These allocations consist of operational and overhead cost pools and are intended to represent the total costs to support a segment. The following tables present financial information for each reportable segment for the year ended December 31: 2022 Corporate Bank Consumer Wealth Other Consolidated (In millions) Net interest income $ 1,961 $ 2,641 $ 184 $ — $ 4,786 Provision for (benefit from) credit losses 287 280 9 (305) 271 Non-interest income 803 1,165 426 35 2,429 Non-interest expense 1,184 2,296 404 184 4,068 Income before income taxes 1,293 1,230 197 156 2,876 Income tax expense (benefit) 323 308 50 (50) 631 Net income $ 970 $ 922 $ 147 $ 206 $ 2,245 Average assets $ 64,532 $ 36,623 $ 2,116 $ 56,121 $ 159,392 2021 Corporate Bank Consumer Wealth Other Consolidated (In millions) Net interest income $ 1,759 $ 2,016 $ 139 $ — $ 3,914 Provision for (benefit from) credit losses 295 254 10 (1,083) (524) Non-interest income 752 1,266 390 116 2,524 Non-interest expense 1,090 2,174 387 96 3,747 Income before income taxes 1,126 854 132 1,103 3,215 Income tax expense 282 213 33 166 694 Net income $ 844 $ 641 $ 99 $ 937 $ 2,521 Average assets $ 59,132 $ 34,309 $ 2,046 $ 58,782 $ 154,269 2020 Corporate Bank Consumer Wealth Other Consolidated (In millions) Net interest income $ 1,684 $ 2,070 $ 140 $ — $ 3,894 Provision for credit losses 281 305 11 733 1,330 Non-interest income 656 1,267 344 126 2,393 Non-interest expense 1,023 2,057 346 217 3,643 Income (loss) before income taxes 1,036 975 127 (824) 1,314 Income tax expense (benefit) 259 244 32 (315) 220 Net income (loss) $ 777 $ 731 $ 95 $ (509) $ 1,094 Average assets $ 61,218 $ 34,530 $ 2,021 $ 40,326 $ 138,095

Commitments and Contingencies Disclosure [Abstract]
Commitment, Contingencies and Guarantees	COMMERCIAL COMMITMENTS Regions issues off-balance sheet financial instruments in connection with lending activities. The credit risk associated with these instruments is essentially the same as that involved in extending loans to customers and is subject to Regions’ normal credit approval policies and procedures. Regions measures inherent risk associated with these instruments by recording a reserve for unfunded commitments based on an assessment of the likelihood that the guarantee will be funded and the creditworthiness of the customer or counterparty. Collateral is obtained based on management’s assessment of the creditworthiness of the customer. Credit risk is represented in unused commitments to extend credit, standby letters of credit and commercial letters of credit. Credit risk associated with these instruments as of December 31 is represented by the contractual amounts indicated in the following table: 2022 2021 (In millions) Unused commitments to extend credit $ 65,460 $ 60,935 Standby letters of credit 1,962 1,779 Commercial letters of credit 75 97 Liabilities associated with standby letters of credit 35 28 Assets associated with standby letters of credit 37 29 Reserve for unfunded credit commitments 118 95 Unused commitments to extend credit —To accommodate the financial needs of its customers, Regions makes commitments under various terms to lend funds to consumers, businesses and other entities. These commitments include (among others) credit card and other revolving credit agreements, term loan commitments and short-term borrowing agreements. Many of these loan commitments have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of these commitments are expected to expire without being funded, the total commitment amounts do not necessarily represent future liquidity requirements. Standby letters of credit —Standby letters of credit are also issued to customers which commit Regions to make payments on behalf of customers if certain specified future events occur. Regions has recourse against the customer for any amount required to be paid to a third party under a standby letter of credit. The credit risk involved in the issuance of these guarantees is essentially the same as that involved in extending loans to clients and as such, the instruments are collateralized when necessary. Historically, a large percentage of standby letters of credit expire without being funded. The contractual amount of standby letters of credit represents the maximum potential amount of future payments Regions could be required to make and represents Regions’ maximum credit risk. Commercial letters of credit —Commercial letters of credit are issued to facilitate foreign or domestic trade transactions for customers. As a general rule, drafts will be drawn when the goods underlying the transaction are in transit. LEGAL CONTINGENCIES Regions and its subsidiaries are routinely subject to actual or threatened legal proceedings, including litigation and regulatory matters, arising in the ordinary course of business. Litigation matters range from individual actions involving a single plaintiff to class action lawsuits and can involve claims for substantial or indeterminate alleged damages or for injunctive or other relief. Regulatory investigations and enforcement matters may involve formal or informal proceedings and other inquiries initiated by various governmental agencies, law enforcement authorities, and self-regulatory organizations, and can result in fines, penalties, restitution, changes to Regions’ business practices, and other related costs, including reputational damage. At any given time, these legal proceedings are at varying stages of adjudication, arbitration, or investigation, and may relate to a variety of topics, including common law tort and contract claims, as well as statutory consumer protection-related claims, among others. Assessment of exposure that could result from legal proceedings is complex because these proceedings often involve inherently unpredictable factors, including, but not limited to, the following: whether the proceeding is in early stages; whether damages or the amount of potential fines, penalties, and restitution are unspecified, unsupported, or uncertain; whether there is a potential for punitive or other pecuniary damages; whether the matter involves legal uncertainties, including novel issues of law; whether the matter involves multiple parties and/or jurisdictions; whether discovery or other investigation has begun or is not complete; whether material facts may be disputed or unsubstantiated; whether meaningful settlement discussions have commenced; and whether the matter involves class allegations. As a result of these complexities, Regions may be unable to develop an estimate or range of loss. Regions evaluates legal proceedings based on information currently available, including advice of counsel. Regions establishes accruals for those matters when a loss is considered probable and the related amount is reasonably estimable. Additionally, when it is practicable and reasonably possible that it may experience losses in excess of established accruals, Regions estimates possible loss contingencies. Regions currently estimates that the aggregate amount of reasonably possible losses that it may experience, in excess of what has been accrued, is immaterial. While the final outcomes of legal proceedings are inherently unpredictable, management is currently of the opinion that the outcomes of pending and threatened matters will not have a material effect on Regions’ business, consolidated financial position, results of operations or cash flows as a whole. As available information changes, the matters for which Regions is able to estimate, as well as the estimates themselves, will be adjusted accordingly. Regions’ estimates are subject to significant judgment and uncertainties, and the matters underlying the estimates will change from time to time. In the event of unexpected future developments, it is possible that an adverse outcome in any such matter could be material to Regions’ business, consolidated financial position, results of operations, or cash flows as a whole for any particular reporting period of occurrence. Some of Regions’ exposure with respect to loss contingencies may be offset by applicable insurance coverage. However, in determining the amounts of any accruals or estimates of possible loss contingencies, Regions does not take into account the availability of insurance coverage. To the extent that Regions has an insurance recovery, the proceeds are recorded in the period the recovery is received. REGULATORY MATTER CONCLUDED DURING 2022 On September 28, 2022, Regions entered into a Consent Order with the CFPB regarding the previously disclosed investigation by the CFPB into certain of Regions' historical overdraft practices and policies. The terms of the Consent Order include payment by Regions of a non-tax deductible $50 million civil monetary penalty and customer redress of approximately $141 million. These payment amounts were mitigated by $50 million in insurance reimbursement proceeds that were received and recorded in non-interest income in the fourth quarter of 2022. GUARANTEES FANNIE MAE LOSS SHARE GUARANTEE Regions sells commercial loans to Fannie Mae through the DUS lending program and through other platforms. The DUS program provides liquidity to the multi-family housing market. Regions services loans sold to Fannie Mae and is required to provide a loss share guarantee equal to one-third of the principal balance for the majority of the commercial servicing portfolio. At December 31, 2022 and 2021, the Company's DUS servicing portfolio totaled approximately $4.9 billion and $4.7 billion, respectively. Regions has additional loans sold to Fannie Mae outside of the DUS program that are also subject to a loss share guarantee and at December 31, 2022 and 2021, these serviced loans totaled approximately $655 million and $400 million, respectively. Regions' maximum quantifiable contingent liability related to all loans subject to a loss share guarantee was approximately $1.8 billion and $1.7 billion at December 31, 2022 and 2021, respectively. The Company would be liable for this amount only if all of the loans it services for Fannie Mae, for which the Company retains some risk of loss, were to default and all of the collateral underlying these loans was determined to be without value at the time of settlement. Therefore, the maximum quantifiable contingent liability is not representative of the actual loss the Company would be expected to incur. The estimated fair value of the associated loss share guarantee recorded as a liability on the Company's consolidated balance sheets was immaterial at both December 31, 2022 and 2021, respectively. Refer to Note 1 for additional information. VISA INDEMNIFICATION As a member of the Visa USA network, Regions, along with other members, indemnified Visa USA against litigation. On October 3, 2007, Visa USA was restructured and acquired several Visa affiliates. In conjunction with this restructuring, Regions' indemnification of Visa USA was modified to cover specific litigation (“covered litigation”). A portion of Visa's proceeds from its IPO was put into escrow to fund the covered litigation. To the extent that the amount available under the escrow arrangement, or subsequent fundings of the escrow account resulting from reductions in the class B share conversion ratio, is insufficient to fully resolve the covered litigation, Visa will enforce the indemnification obligations of Visa USA's members for any excess amount. At this time, Regions has concluded that it is not probable that covered litigation exposure will exceed the class B share value.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2022
Accounting Policies [Abstract]
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block]	BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION The consolidated financial statements include the accounts of Regions, its subsidiaries and certain VIEs. Significant intercompany balances and transactions have been eliminated. Regions considers a voting rights entity to be a subsidiary and consolidates it if Regions has a controlling financial interest in the entity. VIEs are consolidated if Regions has the power to direct the activities of the VIE that significantly impact financial performance and has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE (i.e., Regions is the primary beneficiary). The determination of whether Regions is the primary beneficiary of a VIE is reassessed on an ongoing basis. Investments in companies which are not VIEs but in which Regions has more than minor influence over the operating and financial policies, are accounted for using the equity method of accounting. Investments in VIEs, where Regions is not the primary beneficiary of a VIE, are accounted for using either the proportional amortization method or the equity method of accounting. These investments are included in other assets. The maximum potential exposure to losses relative to investments in VIEs is generally limited to the sum of the outstanding balance, future funding commitments and any related loans to the entity. Loans to these entities are underwritten in substantially the same manner as are other loans and are generally secured. Refer to Note 2 for additional disclosures regarding Regions’ significant VIEs.
Cash and Cash Equivalents, Policy [Policy Text Block]	CASH EQUIVALENTS AND CASH FLOWS Cash equivalents represent assets that can be converted into cash immediately. At Regions, these assets include cash and due from banks, interest-bearing deposits in other banks, and federal funds sold and securities purchased under agreements to resell. Cash flows from loans, either originated or acquired, are classified at that time according to management’s intent to either sell or hold the loan for the foreseeable future. When management’s intent is to sell the loan, the cash flows of that loan are presented as operating cash flows. When management’s intent is to hold the loan for the foreseeable future, the cash flows of that loan are presented as investing cash flows.
Repurchase Agreements, Collateral, Policy [Policy Text Block]	SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL AND SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE Securities purchased under agreements to resell and securities sold under agreements to repurchase are treated as collateralized financing transactions. It is Regions’ policy to take possession of securities purchased under resell agreements either through direct delivery or a tri-party agreement.
Investment, Policy [Policy Text Block]	DEBT SECURITIES Management determines the appropriate accounting classification of debt securities at the time of purchase, based on intent, and periodically re-evaluates such designations. Debt securities are classified as held to maturity when the Company has the intent and ability to hold the securities to maturity. Debt securities held to maturity are presented at amortized cost. Debt securities not classified as held to maturity are classified as available for sale. Debt securities available for sale are presented at estimated fair value with changes in unrealized gains and losses, net of taxes, reported as a component of accumulated other comprehensive income (loss). See the “Fair Value Measurements” section below for discussion of determining fair value. The amortized cost of debt securities classified as held to maturity and available for sale is adjusted for amortization of premiums and accretion of discounts to maturity, or first call date when applicable, using the effective interest method. Such amortization or accretion is included in interest income on securities. Realized gains and losses are included in net securities gains (losses). The cost of securities sold is based on the specific identification method. For debt securities available for sale, the Company reviews its securities portfolio for impairment and determines if impairment is related to credit loss or non-credit loss. In making the assessment of whether a loss is from credit or other factors, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is less than the amortized cost basis, a credit loss exists and an allowance is created, limited by the amount that the fair value is less than the amortized cost basis. Subsequent activity related to the credit loss component (e.g. write-offs, recoveries) is recognized as part of the allowance for credit losses on debt securities available for sale. Securities held to maturity are evaluated under the allowance for credit losses model. For securities which have an expectation of zero nonpayment of the amortized cost basis (e.g. U.S. Treasury securities or agency securities), the expected credit loss is zero. Refer to Note 3 for further detail and information on securities.
Finance, Loan and Lease Receivables, Held-for-sale, Policy [Policy Text Block]	LOANS HELD FOR SALE Regions’ loans held for sale primarily includes commercial loans, investor real estate loans, and residential real estate mortgage loans. Loans held for sale are recorded at either estimated fair value, if the fair value option is elected, or the lower of cost or estimated fair value. Regions has elected to account for residential real estate mortgages originated with the intent to sell at fair value. Intent is established for these conforming residential real estate mortgage loans when Regions enters into an interest rate lock commitment. Gains and losses on these residential mortgage loans held for sale for which the fair value option has been elected are included in mortgage income. Management has elected the fair value option for certain commercial loans originated with the intent to sell and gains and losses on those loans are included in capital markets income. Regions also transfers certain commercial, investor real estate, and residential real estate mortgage portfolio loans that were originally recorded as held for investment to held for sale when management has the intent to sell in the near term. These loans held for sale are recorded at the lower of cost or estimated fair value. At the time of transfer, write-downs on the loans are recorded as charge-offs when credit related and non-interest expense or non-interest income (dependent on loan type) when not credit related and a new cost basis is established. Any subsequent lower of cost or market adjustment is determined on an individual loan basis. Gains and losses on the sale of non-performing commercial and investor real estate loans are included in other non-interest expense. See the “Fair Value Measurements” section below for discussion of determining estimated fair value.
Receivables, Policy [Policy Text Block]	LOANS Regions' loans balance is comprised of commercial, investor real estate and consumer loans. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are considered loans held for investment (or portfolio loans). Loans held for investment are carried at amortized cost (the principal amount outstanding, net of premiums, discounts, unearned income and deferred loan fees and costs). Regions elected to exclude accrued interest receivable balances from the amortized cost basis. Interest receivable is included as a separate line item on the balance sheet. Interest income on all types of loans is accrued based on the contractual interest rate and the principal amount outstanding using methods that approximate the interest method, except for those loans classified as non-accrual. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the contractual or estimated lives of the related loans as an adjustment to the loans’ constant effective yield, which is included in interest income on loans. Direct financing, sales-type and leveraged leases are included within the commercial portfolio segment. See Note 4 for further detail and information on loans and Note 13 for further detail and information on leases. Regions determines past due or delinquency status of a loan based on contractual payment terms. Commercial and investor real estate loans are placed on non-accrual if any of the following conditions occur: 1) collection in full of contractual principal and interest is no longer reasonably assured (even if current as to payment status), 2) a partial charge-off has occurred, unless the loan has been brought current under its contractual terms (original or restructured terms) and the full originally contracted principal and interest is considered to be fully collectible, or 3) the loan is delinquent on any principal or interest for 90 days or more unless the obligation is secured by collateral having a net realizable value (estimated fair value less costs to sell) sufficient to fully discharge the obligation and the loan is in the legal process of collection. Factors considered regarding full collection include assessment of changes in borrower’s cash flow, valuation of underlying collateral, ability and willingness of guarantors to provide credit support, and other conditions. Charge-offs on commercial and investor real estate loans are primarily based on the facts and circumstances of the individual loan and occur when available information confirms the loan is not or will not be fully collectible. Factors considered in making these determinations are the borrower’s and any guarantor’s ability and willingness to pay, the status of the account in bankruptcy court (if applicable), and collateral value. Commercial and investor real estate loan relationships of $250,000 or less are subject to charge-off or charge down to estimated fair value at 180 days past due, based on collateral value. Certain equipment finance loans are subject to charge-off at 120 days past due. Non-accrual and charge-off decisions for consumer loans are dictated by the FFIEC's Uniform Retail Credit Classification and Account Management Policy which establishes standards for the classification and treatment of consumer loans. The charge-off process drives consumer non-accrual status. If a consumer loan secured by real estate in a first lien position (residential first mortgage or home equity) becomes 180 days past due, Regions evaluates the loan for non-accrual status and potential charge-off based on net loan to value exposure. For home equity loans and lines of credit in a second lien position, the evaluation is performed at 120 days past due. If a loan is secured by collateral having a net realizable value sufficient to fully discharge the obligation, then a partial write-down is not necessary and the loan remains on accrual status, provided it is in the process of legal collection. If a partial charge-off is necessary as a result of the evaluation, then the remaining balance is placed on non-accrual. Consumer loans not secured by real estate are generally charged-off at either 120 days past due for closed-end loans, 180 days past due for open-end loans other than credit cards or the end of the month in which the loan becomes 180 days past due for credit cards. When loans are placed on non-accrual status, the accrual of interest, amortization of loan premium, accretion of loan discount and amortization/accretion of deferred net loan fees/costs are discontinued. When a commercial or investor real estate loan is placed on non-accrual status, uncollected interest accrued in the current year is reversed and charged to interest income. Uncollected interest accrued from prior years on commercial and investor real estate loans placed on non-accrual status in the current year is charged against the allowance for loan losses. When a consumer loan is placed on non-accrual status, all uncollected interest accrued is reversed and charged to interest income due to immateriality. Interest collections on commercial and investor real estate non-accrual loans are applied as principal reductions. Interest collections on consumer non-accrual loans are recorded using the cash basis, due to immateriality. All loans on non-accrual status may be returned to accrual status and interest accrual resumed if all of the following conditions are met: 1) the loan is brought contractually current as to both principal and interest, 2) future payments are reasonably expected to continue being received in accordance with the terms of the loan and repayment ability can be reasonably demonstrated, and 3) the loan has been performing for at least six months. Purchased Loans Purchased loans are recorded at their fair value at the acquisition date. Purchased loans are evaluated and classified as either PCD, which indicates that the loan has experienced more than insignificant credit deterioration since origination, or non-PCD loans. For PCD loans, the sum of the loans' purchase price and allowance for credit losses, which is determined using the same methodology as originated loans, becomes their initial amortized cost basis. For non-PCD loans, the difference between the fair value and the par value is considered the fair value mark. The non-credit discount or premium related to PCD loans and the fair value mark on non-PCD loans is accreted or amortized into interest income over the contractual life of the loan using the effective interest method. Subsequent changes in the allowance to the PCD and non-PCD loans are recognized in the provision for credit losses.
Loans and Leases Receivable, Troubled Debt Restructuring Policy [Policy Text Block]	TDRs TDRs are loans in which the borrower is experiencing financial difficulty at the time of restructuring, and Regions has granted a concession to the borrower. TDRs are undertaken in order to improve the likelihood of recovery on the loan and may take the form of modifications made with the stated interest rate lower than the current market rate for new debt with similar risk, other modifications to the structure of the loan that fall outside of normal underwriting policies and procedures, or in limited circumstances forgiveness of principal and/or interest. Insignificant delays in payments are not considered TDRs. TDRs can involve loans remaining on non-accrual, moving to non-accrual, or continuing on accrual status, depending on the individual facts and circumstances of the borrower. TDRs are subject to policies governing accrual/non-accrual evaluation consistent with all other loans of the same product type as discussed in the “Loans” section above. The CAP was designed to evaluate potential consumer loan participants as early as possible in the life cycle of the troubled loan (as described in Note 5). Many of the modifications are finalized without the borrower ever reaching the applicable number of days past due, and therefore the loan may never be placed on non-accrual. Accordingly, given the positive impact of the restructuring on the likelihood of recovery of cash flows due under the modified terms, accrual status continues to be appropriate for these loans. As provided in the CARES Act passed into law on March 27, 2020, and subsequently extended through the Consolidated Appropriations Act signed into law on December 27, 2020, certain loan modifications related to the COVID-19 pandemic beginning March 1, 2020, through the earlier of 60 days after the end of the pandemic or January 1, 2022, were eligible for relief from TDR classification. Regions elected this provision of both Acts; therefore, modified loans that met the required guidelines for relief were not considered TDRs.
Financing Receivable, Allowance for Credit Losses, Policy for Uncollectible Amounts [Policy Text Block]	ALLOWANCE Regions adopted CECL on January 1, 2020, which replaced the incurred loss methodology to estimate the allowance with the expected loss methodology. Regions elected not to estimate an allowance on interest receivable balances because the Company has non-accrual polices in place that provide for the accrual of interest to cease on a timely basis when all contractual amounts due are not expected. The allowance is intended to cover expected credit losses over the contractual life of loans measured at amortized cost, including unfunded commitments. Management’s measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and R&S forecasts that affect the collectability of the reported amount. For periods beyond which Regions makes or obtains such R&S forecasts, Regions reverts to historical credit loss information. Regions maintains an appropriate level of allowance that falls within an acceptable range of estimated losses, measured in accordance with GAAP. Management's determination of the appropriateness of the allowance is based on many factors, including, but not limited to, an evaluation and rating of the loan portfolio; historical loan loss experience; current economic conditions; collateral values securing loans; levels of problem loans; volume, growth, quality and composition of the loan portfolio; regulatory guidance; R&S economic forecasts; and other relevant factors. Changes in any of these factors, assumptions, or the availability of new information, could require that the allowance be adjusted in future periods, perhaps materially. Loss forecasting models are built on historical loss information and then applied to the current portfolio. Outputs from the loss forecasting models in combination with Regions' qualitative framework, and other analyses are used to inform management in its estimation of Regions' expected credit losses. Actual losses could vary, perhaps materially, from management’s estimates. The entire allowance is available to cover all charge-offs that arise from the loan portfolio. Regions' allowance calculation is a significant estimate. Regions uses its best judgment to assess economic conditions and loss data in estimating the allowance and these estimates are subject to periodic refinement based on changes in underlying external or internal data. Therefore, assumptions and decisions driving the estimate may change as conditions change. These assumptions and estimates are detailed below. R & S forecast period During the two-year R&S forecast period, Regions incorporates forward-looking information by utilizing its internally developed and approved Base economic forecast. The scenario is developed by the Chief Economist and approved through a formal governance process. The Base forecast considers market forward/consensus information and is consistent with the Company's organization-wide economic outlook. When appropriate, additional scenarios, including externally created scenarios, are considered as part of the determination of the allowance. Reversion period Regions utilizes an exponential reversion approach that reverts to TTC rates derived from the simple average of all historical quarterly observations for PD, LGD, EAD and prepayment rates. The length of the reversion period differs by class of financing receivable. Historical loss period Regions does not adjust historical loss information for existing economic conditions or expectations of future economic conditions for periods that are beyond the R&S period. Regions utilizes internal historical loss information; however, there are certain loan portfolios that also benefit from the use of external or other reference data due to identified limitations with internal historical data. Contractual life Regions estimates expected credit losses over the contractual life of a loan. Regions defines contractual life for non-revolving loans as contractual maturity, net of estimated prepayments and excluding expected extensions, renewals and modifications unless 1) Regions has a reasonable expectation at the reporting date that it will execute a TDR with the borrower ("RETDR") or 2) extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by Regions. RETDR Regions individually identifies commercial and investor real estate loans for inclusion as RETDRs. The identification criteria are based on internal risk ratings and time to maturity. Regions typically does not identify consumer loans as RETDRs due to the insignificant time period between initial contact with a customer regarding a loan modification and when a TDR modification is consummated. The RETDR status extends the life of the loan past the contractual maturity and includes the allowance impact of interest rate concessions. Loans identified as RETDRs will be treated consistently from a modeling/reserving perspective as loans identified as TDRs. Contractual term extensions (borrower versus lender option to renew) Regions' consumer loan contracts do not permit automatic extensions or unilateral customer extensions, and Regions retains the right to approve or deny any extension requested from the borrower. As a result, extensions and renewal options are not included in the life of consumer loans for the purposes of calculating the allowance. Similarly, Regions does not include extension and renewal options in the life of commercial loans for the purposes of calculating the allowance, unless it is a RETDR. Most commercial products do not offer borrowers a unilateral right to renew or extend. Contractual life of credit card receivables Regions estimates the life of credit card receivables based on the amount and timing of payments expected to be collected. Regions' credit card allowance estimate only considers the amount of debt outstanding at the reporting date (the current position) because undrawn balances are unconditionally cancellable. Regions classifies credit card accounts into one of three payment patterns: dormant, transacting or revolving. The dormant accounts are idle, carry no balance, and do not contribute to the allowance. The transacting account holders tend to pay the entire balance due every month and are, therefore, subject to practically no interest charges. For transactor accounts, the current position balance is expected to be paid off in one quarter. The revolving accounts tend to be subject to interest charges, and their current position balance liquidates over time. Regions' credit card portfolio is comprised primarily of revolvers. Collateral-dependent loans Regions' collateral-dependent consumer loans are loans secured by collateral (primarily real estate) that meet the partial charge-down requirements disclosed within this section. Regions evaluates significant commercial and investor real estate loans that are in financial difficulty and secured by collateral to determine if they are collateral dependent. For any collateral-dependent loans that meet Regions' specific allowance criteria (see below), Regions will calculate the allowance based on the fair value of collateral methodology. For collateral-dependent consumer, commercial and investor real estate loans that do not meet Regions' specific allowance criteria (as described below), Regions considers the value of the collateral through the LGD component of the loss model based on collateral type. Credit enhancements Regions' estimate of credit losses reflects how credit enhancements, other than those that are freestanding contracts, mitigate expected credit losses on financial assets. In the event that a credit enhancement arrangement is considered to be a freestanding contract, Regions excludes the credit enhancement from the related loan when estimating expected credit losses. Unfunded commitments and other off-balance sheet items Regions records a liability or allowance for credit losses for the unfunded portion of a loan commitment in the event that the issuer does not have the unconditional right to cancel the commitment. For an unfunded commitment to be considered unconditionally cancellable, Regions must be able to, at any time, with or without cause, refuse to extend credit. The liability is measured over the full contractual period for which Regions is exposed to credit risk through a current obligation to extend credit. In determining the liability, management considers the likelihood that funding will occur, and if funded, the related expected credit losses under the allowance model. Regions' off-balance sheet unfunded commitments in the form of home equity lines, standby letters of credit, commercial letters of credit and commercial revolving products that are deemed to be conditionally cancellable will include unfunded balances within the allowance estimate. Future advances from certain unfunded commitments and other revolving products where Regions does have the unconditional right to cancel these agreements will not be included. CALCULATION OF ALLOWANCE FOR CREDIT LOSSES Pooled allowances The allowance is measured on a collective (pool) basis when similar risk characteristics exist. Segmentation variables for commercial and investor real estate segments include product, loan size, collateral type, risk rating and term. Segmentation variables considered for consumer segments include product, FICO, LTV, age, TDR status, etc. The allowance is estimated for most portfolios and classes using econometric models to estimate expected credit losses. In general, discounted cash flow models are not used for the purpose of estimating expected losses for the purpose of the ACL. Most of the econometric models include PD, LGD, and EAD components. Less complex estimation methods are used for smaller loan portfolios. Specific allowances Due to their size, complexity and individualized risk characteristics and monitoring, the allowance for significant non-accrual commercial and investor real estate loans (including TDRs) and unfunded commitments is measured on an individual basis. Loans evaluated individually are not included in the collective evaluation. Regions generally measures the allowance for these loans based on the present value of estimated cash flows, considering all facts and circumstances specific to the borrower and market and economic conditions. The allowance measurement for collateral-dependent loans that meet the individually evaluated threshold is based on the fair value of collateral methodology. TDRs and RETDRs Loans identified as TDRs and RETDRs are included in their respective loan pools (if they do not qualify for specific evaluation) and losses are determined by allowance models. The effect of the interest rate concession on these loans is considered through a post-model adjustment. Qualitative framework While quantitative allowance methodologies strive to reflect all risk factors, any estimate involves assumptions and uncertainties resulting in some level of imprecision. Imprecision exists in the estimation process due to the inherent time lag between obtaining information, performing the calculation, as well as variations between estimates and actual outcomes. Regions adjusts the allowance considering quantitative and qualitative factors which may not be directly measured in the modeled calculations. Regions' qualitative framework provides for specific quantitatively supported model adjustments and general imprecision adjustments. Specific model adjustments capture highly specific issues or events that Regions believes are not adequately captured in model outcomes. General imprecision adjustments address other sources of imprecision that are not specifically identifiable or quantifiable to a particular loan portfolio and have not been captured by the model or by a specific model adjustment. Regions considers general imprecision in three dimensions; economic forecast imprecision, model imprecision, and process imprecision. Refer to Note 5 for further discussion regarding the calculation of the allowance for credit losses.
Lessee, Leases [Policy Text Block]	LESSEES Regions' lease portfolio is primarily composed of property leases that are classified as either operating or finance leases with the majority classified as operating leases. Property leases, which primarily include office locations and retail branches, typically have original lease terms ranging from 1 year to 20 years, some of which may also include an option to extend the lease beyond the original lease term. In some circumstances, Regions may also have an option to terminate the lease early with advance notice. Regions includes renewal and termination options within the lease term if deemed reasonably certain of exercise. As most leases do not state an implicit rate, Regions utilizes the incremental borrowing rate based on information available at the lease commencement date to determine the present value of lease payments. Leases with a term of 12 months or less are not recorded on the balance sheet. Regions continues to recognize lease payments as an expense over the lease term as appropriate.
Lessor, Leases [Policy Text Block]	LESSORS Regions engages in both direct financing and sales-type leasing. Regions also has a portfolio of leveraged leases. These arrangements provide equipment financing for leased assets, such as vehicles and aircraft. At the commencement date, Regions (lessor) enters into an agreement with the customer (lessee) to lease the underlying equipment for a specified lease term. The lease agreements may provide customers the option to terminate the lease by buying the equipment at fair market value at the time of termination or at the end of the lease term. Regions' equipment finance asset management group performs due diligence procedures on the lease residual and overall equipment values as part of the origination process. Regions performs lease residual value reviews on an ongoing basis. In order to manage the residual value risk inherent in some of its direct financing leases, Regions purchases residual value insurance from an independent third party.
Other Earning Assets [Policy Text Block]	OTHER EARNING ASSETSOther earning assets consist of investments in FRB stock, FHLB stock, marketable equity securities and other miscellaneous earning assets. Ownership of FRB and FHLB stock is a requirement for all banks seeking membership into and access to the services provided by these banking systems. These shares are accounted for at amortized cost, which approximates fair value. Marketable equity securities are recorded at fair value with changes in fair value reported in net income. See Note 7 for additional information.
Property, Plant and Equipment, Policy [Policy Text Block]	PREMISES AND EQUIPMENT Premises and equipment are stated at cost, less accumulated depreciation and amortization, as applicable. Land is carried at cost. Depreciation expense is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements (or the terms of the leases, if shorter). Generally, premises and leasehold improvements are depreciated or amortized over 7-40 years. Furniture and equipment are generally depreciated or amortized over 3-10 years. Premises and equipment are evaluated for impairment at least annually, or more often if events or circumstances indicate that the carrying value of the asset may not be recoverable. Maintenance and repairs are charged to non-interest expense in the consolidated statements of income. Improvements that either add functionality or extend the useful life of the asset are capitalized to the carrying value and depreciated. See Note 8 for detail of premises and equipment.
Goodwill and Intangible Assets, Policy [Policy Text Block]	INTANGIBLE ASSETS Intangible assets include goodwill, which is the excess of cost over the fair value of net assets of acquired businesses, and other identifiable intangible assets. Other identifiable intangible assets primarily include relationship assets, agency commercial real estate licenses, and amounts capitalized related to the value of PCCR. Other identifiable intangibles assets are primarily amortized over their expected useful lives while agency commercial real estate licenses are non-amortizing. The Company’s goodwill is tested for impairment on an annual basis in the fourth quarter, or more often if events or circumstances indicate that there may be impairment. Regions assesses the following indicators of goodwill impairment for each reporting period: • Recent operating performance, • Changes in market capitalization, • Regulatory actions and assessments, • Changes in the business climate (including legislation, legal factors and competition), • Company-specific factors (including changes in key personnel, asset impairments, and business dispositions), and • Trends in the banking industry. Adverse changes in the economic environment, declining operations, or other factors could result in a decline in the implied estimated fair value of goodwill. Accounting guidance permits the Company to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying value. If, based on the weight of the evidence, the Company determines it is more likely than not that the fair value exceeds book value, then an impairment test is not necessary. If the Company elects to bypass the qualitative assessment, or concludes that it is more likely than not that the fair value is less than the carrying value, a goodwill impairment test is performed. The Company compares the estimated fair value of a reporting unit with its carrying amount, including goodwill. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired. If the carrying amount of a reporting unit exceeds its estimated fair value, an impairment loss is recognized in non-interest expense in an amount equal to that excess. For purposes of performing the qualitative assessment, Regions evaluates events and circumstances which may include, but are not limited to, events and circumstances since the last impairment analysis, recent operating performance including reporting unit performance, changes in market capitalization, regulatory actions and assessments, changes in the business climate, company-specific factors, and trends in the banking industry to determine if it is more likely than not that the fair value of a reporting unit exceeds its carrying amount. For purposes of performing the goodwill impairment test, if applicable, Regions uses both income and market approaches to value its reporting units. The income approach, which is the primary valuation approach, consists of discounting projected long-term future cash flows, which are derived from internal forecasts and economic expectations for the respective reporting units. The significant inputs to the income approach include expected future cash flows, the long-term target equity ratios, and the discount rate. Other identifiable intangible assets are reviewed at least annually (usually in the fourth quarter) for events or circumstances that could impact the recoverability of the intangible asset. These events could include loss of core deposits, loss of relationships, significant losses of credit card or other types of acquired customer accounts and/or balances, increased competition, or adverse changes in the economy. To the extent other identifiable intangible assets are deemed unrecoverable, impairment losses are recorded in non-interest expense and reduce the carrying amount of the asset. Refer to Note 9 for further detail and discussion of the results of the goodwill and other identifiable intangibles impairment tests.
Transfers and Servicing of Financial Assets, Policy [Policy Text Block]	ACCOUNTING FOR TRANSFERS AND SERVICING OF FINANCIAL ASSETS Regions accounts for transfers of financial assets as sales when control over the transferred assets is surrendered. Control is generally considered to have been surrendered when 1) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and 3) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If these sale criteria are met, the transferred assets are removed from the Company’s balance sheet and a gain or loss on sale is recognized. If not met, the transfer is recorded as a secured borrowing, and the assets remain on the Company’s balance sheet, the proceeds from the transaction are recognized as a liability, and gain or loss on sale is deferred until the sale criterion are achieved. Regions has elected to account for its residential MSRs using the fair value measurement method. Under the fair value measurement method, residential MSRs are measured at estimated fair value each period with changes in fair value recorded as a component of mortgage income. The fair value of residential MSRs is calculated using various assumptions including future cash flows, market discount rates, expected prepayment rates, servicing costs and other factors. A significant change in prepayments of residential mortgages in the servicing portfolio could result in significant valuation adjustments, thus creating potential volatility in the carrying amount of residential MSRs. The valuation method relies on an OAS to consider prepayment risk and equate the asset's discounted cash flows to its market price. See the “Fair Value Measurements” section below for additional discussion regarding determination of fair value. Regions is a DUS lender. The DUS program provides liquidity to the multi-family housing market. Regions' related commercial MSRs are recorded in other assets at the lower of cost or estimated fair value and are amortized in proportion to, and over the estimated period that net servicing income is expected to be received based on projections of the amount and timing of estimated future net cash flows. The amount and timing of estimated future net cash flows are updated based on actual results and updated projections. Regions periodically evaluates these commercial MSRs for impairment. Regions has a one-third loss share guarantee associated with the majority of the DUS servicing portfolio. The other two-thirds loss share guarantee is retained by Fannie Mae. The estimated fair value of the loss share guarantee is recorded in other liabilities. Refer to Note 6 for further information on servicing of financial assets.
Finance, Loan and Lease Receivables, Held for Investments, Foreclosed Assets Policy [Policy Text Block]	FORECLOSED PROPERTY AND OTHER REAL ESTATE Other real estate and certain other assets acquired in satisfaction of indebtedness (“foreclosure”) are carried in other assets at the lower of the recorded investment in the loan or estimated fair value less estimated costs to sell the property. At the date of transfer from the loan portfolio, if the recorded investment in the loan exceeds the property’s estimated fair value less estimated costs to sell, a write-down is recorded against the allowance. Regions allows a period of up to 60 days after the date of transfer to record finalized write-downs as charge-offs against the allowance in order to properly accumulate all related invoices and updated valuation information, if necessary. Subsequent to transfer, Regions obtains valuations from professional valuation experts and/or third party appraisers on at least an annual basis. See the “Fair Value Measurements” section below for additional discussion regarding determination of fair value. Subsequent to transfer and the additional 60 days, any further write-downs are recorded as other non-interest expense. Gain or loss on the sale of foreclosed property and other real estate is included in other non-interest expense.
Equity Method Investments Issuances, Policy [Policy Text Block]	OTHER INVESTMENT ASSETS Regions has investments of approximately $223 million and $207 million at December 31, 2022 and 2021, respectively, that are recognized in other assets and accounted for using either the equity method of accounting or the measurement alternative to fair value for equity investments without a readily determinable fair value. Equity method investments consist primarily of investments in SBICs and private equity funds. Under the equity method of accounting, Regions records its proportionate share of the profits or losses of the investment entity as an adjustment to the carrying value of the investment and as a component of other non-interest income. Dividends and distributions received or receivable from these investments are recorded as reductions to the carrying value of the investments. The net balances of equity method investments were approximately $153 million and $136 million at December 31, 2022 and 2021, respectively. Equity investments that do not meet the criteria to be accounted for under the equity method and do not have a readily determinable fair value are accounted for at cost under the measurement alternative to fair value with adjustments for impairment and observable price changes as applicable. Dividends received or receivable and observable price changes from these investments are included as components of other non-interest income. These investments consist primarily of investments in strategic partners and certain CRA projects. The carrying amounts of these investments were $70 million and $71 million at December 31, 2022 and 2021, respectively.
Derivatives, Policy [Policy Text Block]	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES The Company enters into derivative financial instruments to manage interest rate risk, facilitate asset/liability management strategies and manage other exposures. These instruments primarily include interest rate swaps, options on interest rate swaps, options including interest rate caps and floors, Eurodollar futures, forward rate contracts and forward sale commitments. All derivative financial instruments are recognized as other assets or other liabilities, as applicable, at estimated fair value. Regions enters into master netting agreements with counterparties and/or requires collateral to cover exposures. In at least some cases, counterparties post collateral at a zero threshold regardless of credit rating. The majority of interest rate derivatives traded by Regions with dealing counterparties are subject to mandatory clearing through a central clearinghouse. The variation margin payments made for derivatives cleared through a central clearinghouse are legally characterized as settlements of the derivatives. The counterparty risk for cleared trades effectively moves from the executing broker to the clearinghouse allowing Regions to benefit from the risk mitigation controls in place at the respective clearinghouse. Interest rate swaps are agreements to exchange interest payments based upon notional amounts. Interest rate swaps subject Regions to market risk associated with changes in interest rates, changes in interest rate volatility, as well as the credit risk that the counterparty will fail to perform. Option contracts involve rights to buy or sell financial instruments on a specified date or over a period at a specified price. These rights do not have to be exercised. Some option contracts such as interest rate floors, involve the exchange of cash based on changes in specified indices. Interest rate floors are contracts to hedge interest rate declines based on a notional amount, generally associated with a principal balance at risk. Interest rate floors subject Regions to market risk associated with changes in interest rates, changes in interest rate volatility, as well as the credit risk that the counterparty will fail to perform. Forward rate contracts are commitments to buy or sell financial instruments at a future date at a specified price or yield. Regions primarily enters into forward rate contracts on marketable instruments, which expose Regions to market risk associated with changes in the value of the underlying financial instrument, as well as the credit risk that the counterparty will fail to perform. Eurodollar futures are futures contracts on Eurodollar deposits. Eurodollar futures subject Regions to market risk associated with changes in interest rates. Because futures contracts are cash settled daily through a margining process in an exchange, there is minimal credit risk associated with Eurodollar futures. Forward sale commitments are sales of securities at a specified price at a future date. Forward sale commitments subject Regions to market risk associated with changes in market value, as well as the credit risk that the counterparty will fail to perform. The Company elects to account for certain derivative financial instruments as accounting hedges which, based on the exposure being hedged, are either fair value or cash flow hedges. Fair value hedge relationships mitigate exposure to the change in fair value of the hedged risk in an asset, liability or firm commitment. Certain fair value hedges may be entered into using the portfolio layer method, which allows the Company to hedge the interest rate risk of non-prepayable and prepayable financial assets by designating as the hedged item a stated amount of a closed portfolio that is expected to be outstanding for the designated hedge period(s). Under the fair value hedging model, gains or losses attributable to the change in fair value of the derivative instrument, as well as the gains and losses attributable to the change in fair value of the hedged item, are recognized in interest income or interest expense in the same income statement line item with the hedged item in the period in which the change in fair value occurs. To the extent the changes in fair value of the derivative do not offset the changes in fair value of the hedged item, the difference is recognized. The corresponding adjustment to the hedged asset or liability is included in the basis of the hedged item, while the corresponding change in the fair value of the derivative instrument is recorded as an adjustment to other assets or other liabilities, as applicable. Cash flow hedge relationships mitigate exposure to the variability of future cash flows or other forecasted transactions. For cash flow hedge relationships, the entire change in the fair value of the hedging instrument would be recorded in accumulated other comprehensive income (loss) except for amounts excluded from the assessment of hedge effectiveness. Amounts recorded in accumulated other comprehensive income (loss) are recognized in earnings in the same income statement line item where the earnings effect of the hedged item is presented in the period or periods during which the hedged item impacts earnings. The Company formally documents all hedging relationships, as well as its risk management objective and strategy for entering into various hedge transactions. The Company performs periodic qualitative and quantitative assessments to determine whether the hedging relationship has been highly effective in offsetting changes in fair values or cash flows of hedged items and whether the relationship is expected to continue to be highly effective in the future. If a hedge relationship is de-designated or if hedge accounting is discontinued because the hedged item no longer exists, or does not meet the definition of a firm commitment, or because it is probable that the forecasted transaction will not occur, the derivative will continue to be recorded as an other asset or other liability in the consolidated balance sheets at its estimated fair value, with changes in fair value recognized in other non-interest expense. Any asset or liability that was recorded pursuant to recognition of the firm commitment is removed from the consolidated balance sheets and recognized in other non-interest expense. Gains and losses that were unrecognized and aggregated in accumulated other comprehensive income (loss) pursuant to the hedge of a forecasted transaction are recognized immediately in other non-interest expense. Derivative contracts for which the Company has not elected to apply hedge accounting are classified as other assets or liabilities with gains and losses related to the change in fair value recognized in capital markets income or mortgage income, as applicable, in the statements of income during the period. These positions, as well as non-derivative instruments, are used to mitigate economic and accounting volatility related to customer derivative transactions, the mortgage pipeline and the fair value of residential MSRs. Regions enters into interest rate lock commitments, which are commitments to originate mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. Accordingly, such commitments are recorded at estimated fair value with changes in fair value recorded in mortgage income or capital markets income, as applicable. Regions also has corresponding forward sale commitments related to these interest rate lock commitments, which are recorded at estimated fair value with changes in fair value recorded in mortgage income or capital markets income, as applicable. See the “Fair Value Measurements” section below for additional information related to the valuation of interest rate lock commitments. Regions enters into various derivative agreements with customers desiring protection from possible future market fluctuations. Regions manages the market risk associated with these derivative agreements. The contracts in this portfolio for which the Company has elected not to apply hedge accounting are marked-to-market through capital markets income and included in other assets and other liabilities. Concurrent with the election to use fair value measurement for residential MSRs, Regions began using various derivative instruments to mitigate the impact of changes in the fair value of residential MSRs in the statements of income. This effort may involve the use of various derivative instruments, including, but not limited to, forwards, futures, swaps, options, and TBA's designed as derivative instruments. These derivatives are carried at estimated fair value, with changes in fair value reported in mortgage income. Refer to Note 20 for further discussion and details of derivative financial instruments and hedging activities.
Income Tax, Policy [Policy Text Block]	INCOME TAXES The Company accounts for income taxes using the asset and liability method. Accrued income taxes and the net balance of deferred tax assets and liabilities are reported in other assets or other liabilities in the consolidated balance sheets, as appropriate. The Company reflects the expected amount of income tax to be paid or refunded during the year as current income tax expense or benefit, as applicable. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that the Company expects will apply at the time when the deferred tax assets and liabilities are expected to be realized. Deferred tax assets are also recorded for any tax attributes, such as tax credit and net operating loss carryforwards. The Company determines the realization of deferred tax assets by considering all positive and negative evidence available, and a valuation allowance is recorded for any deferred tax assets that are not more-likely-than-not to be realized. Any effect of a change in federal and state tax rates on deferred tax assets and liabilities is recognized in income tax expense in the period that includes the enactment date. The Company will evaluate and recognize income tax benefits related to any uncertain tax positions using the recognition and cumulative-probability measurement thresholds. If the Company does not believe that it is more likely than not that an uncertain tax position will be sustained, the Company records a liability for the uncertain tax position. If a tax benefit is more-likely-than-not of being sustained based on the technical merits, the Company utilizes the cumulative probability measurement and records an income tax benefit equivalent to the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with a taxing authority. The Company recognizes interest and penalties related to unrecognized tax benefits within current income tax expense. The Company applies the proportional amortization method in accounting for its qualified affordable housing investments. This method recognizes the amortized cost of the investment as a component of income tax expense. The deferral method of accounting is used for investments that generate investment tax credits. Under this method, the investment tax credits are recognized as a reduction of the related asset.
Treasury Stock and Share Repurchases [Policy Text Block]	TREASURY STOCK AND SHARE REPURCHASES The purchase of the Company’s common stock is recorded at cost. At the date of repurchase, shareholders' equity is reduced by the repurchase price. Upon retirement, or upon purchase for constructive retirement, treasury stock would be reduced by the cost of such stock with the excess of repurchase price over par or stated value recorded in additional paid-in capital. If the Company subsequently reissues treasury shares, treasury stock is reduced by the cost of such stock with differences recorded in additional paid-in capital or retained earnings, as applicable. Pursuant to recent share repurchase programs, shares repurchased were immediately retired, and therefore were not included in treasury stock. The Company's policy related to these share repurchases is to reduce its common stock based on the par value of the shares repurchased and to reduce its additional paid-in capital for the excess of the repurchase price over the par value.
Compensation Related Costs, Policy [Policy Text Block]	SHARE-BASED PAYMENTS Regions sponsors stock plans which most commonly include restricted stock (i.e., unvested common stock) units, restricted stock awards and performance stock units. The Company accounts for share-based payments under the fair value recognition provisions whereby compensation cost is measured based on the estimated fair value of the award at the grant date and is recognized in the consolidated financial statements on a straight-line basis over the requisite service period for service-based awards. The fair value of restricted stock units, restricted stock awards or performance stock units is determined based on the closing price of Regions common stock on the date of grant. Historical data is also used to estimate future employee attrition, which is considered in calculating estimated forfeitures. Estimated forfeitures are adjusted when actual forfeitures differ from estimates, resulting in the recognition of compensation cost only for awards that vest. The effect of a change in estimated forfeitures is recognized through a cumulative catch-up adjustment that is included in salaries and employee benefits expense in the period of the change in estimate. As compensation cost is recognized, a deferred tax asset is recorded that represents an estimate of the future tax deduction from exercise or release of restrictions. At the time the share-based awards are exercised, cancelled, have expired, or restrictions are released, the Company may be required to recognize an adjustment to tax expense depending on the market price of the Company’s common stock. Prior to 2021, Regions' sponsored plans also included stock options. Refer to Note 1 "Summary of Significant Accounting Policies" and Note 16 "Share-Based Payments" of the Annual Report on Form 10-K for the year ended December 31, 2021, for additional information regarding the accounting and reporting policies related to stock options. See Note 16 for further discussion and details of share-based payments.
Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]	EMPLOYEE BENEFIT PLANS Regions uses an expected long-term rate of return applied to the fair market value of assets as of the beginning of the year and the expected cash flows during the year for calculating the expected investment return on all pension plan assets. At a minimum, amortization of the net gain or loss included in accumulated other comprehensive income resulting from experience different from that assumed and from changes in assumptions is included as a component of net periodic benefit cost if, as of the beginning of the year, that net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market value of plan assets. If amortization is required, the minimum amortization is that excess divided by the average remaining service period of active participating employees expected to receive benefits under the plans. Regions records the service cost component of net periodic pension and postretirement benefit cost in salaries and employee benefits expense. The other components of net periodic pension and postretirement benefit cost are recorded in other non-interest expense. Regions uses a third-party actuary to compute the remaining service period of active participating employees. This period reflects expected turnover, pre-retirement mortality, and other applicable employee demographics. See Note 17 for further discussion and details of employee benefit plans.
Revenue Recognition, Policy [Policy Text Block]	REVENUE RECOGNITION The Company records revenue when control of the promised products or services is transferred to the customer, in an amount that reflects the consideration Regions expects to be entitled to receive in exchange for those products or services. Related to contract costs, Regions expenses sales commissions and any related contract costs when incurred because the amortization period would be one year or less. Related to remaining performance obligations, Regions does not disclose the value of unsatisfied performance obligations for 1) contracts with an original expected length of one year or less and 2) contracts for which revenue is recognized at the amount to which Regions has the right to invoice for services performed. Interest Income The largest source of revenue for Regions is interest income. Interest income is recognized using the interest method driven by nondiscretionary formulas based on written contracts, such as loan agreements or securities contracts. Service Charges on Deposit Accounts Service charges on deposit accounts include overdraft fees and other service charges. When a depositor presents an item for payment in excess of available funds, overdraft fees are earned when Regions, at its discretion, provides the necessary funds to complete the transaction. Prior to mid-2022, service charges on deposit accounts also included non-sufficient fund fees, which were earned when a depositor presented an item for payment in excess of available funds and an item was returned unpaid. Regions generates other service charges by providing depositors proper safeguard and remittance of funds as well as by providing optional services for depositors, such as check imaging or treasury management, that are performed upon the depositor’s request. Charges for the proper safeguard and remittance of funds are recognized monthly, as the customer retains funds in the account. Regions recognizes revenue for other optional services when the customer uses the selected service to execute a transaction (e.g., execute an ACH wire). Card and ATM Fees Card and ATM fees include the combined amounts of credit card, debit card, and ATM related revenue. The majority of the fees are card interchange where Regions earns a fee for remitting cardholder funds (or extends credit) via a third party network to merchants. Regions satisfies performance obligations for each transaction when the card is used and the funds are remitted. The network establishes interchange fees that the merchant remits to Regions for each transaction, and Regions incurs costs from the network for facilitating the interchange with the merchant. Due to its inability to establish prices and direct activities of the related processing network’s service, Regions is deemed the agent in this arrangement and records interchange revenues net of related costs. Regions also pays consideration to certain commercial card holders based on interchange fees and contractual volume. These costs are recognized as a reduction to interchange income. Card and ATM fees also include ATM fee income generated from allowing a Regions cardholder to withdraw funds from a non-Regions ATM and from allowing a non-Regions cardholder to withdraw funds from a Regions ATM. Regions satisfies performance obligations for each transaction when the withdrawal is processed. Regions does not direct activities of the related processing network’s service and recognizes revenue on a net basis as the agent in each transaction. Investment Management and Trust Fee Income Investment management and trust fee income represents revenue generated from asset management services provided to individuals, businesses, and institutions. Regions has a fiduciary responsibility to the beneficiary of the trust to perform agreed upon services which can include investing the assets, periodic reporting to the beneficiaries, and providing tax information regarding the trust. In exchange for these trust and custodial services, Regions collects fee income from beneficiaries as contractually determined via fee schedules. Regions’ performance obligations to customers are primarily satisfied over time as the services are performed and provided to the customer. Mortgage Income Mortgage income is recognized when earned or as each transaction occurs through the origination and servicing of residential mortgage loans for long-term investors and sales of residential mortgage loans in the secondary market. Mortgage income also includes any fair value adjustments for mortgage loans Regions has elected to measure under the fair value option and fair value adjustments related to mortgage servicing rights. Capital Markets Income Regions generates capital markets fee revenue through capital raising activities which include revenue streams such as securities underwriting and placement, loan syndication and placement, as well as foreign exchange, derivatives, merger and acquisition and other advisory services. For those revenue streams, revenue is primarily recognized at a point in time which coincides with the satisfaction of a single performance obligation, typically the transaction closing. Securities underwriting and placement fees involve the issuing and distribution of securities for an underwriting fee from customers. The underwriting fee is a single performance obligation which is satisfied at the time that the transaction is closed, and the amount of the fee is either a fixed or variable percentage based on the deal value which is determinable at the time of deal closing. Regions generates revenue from affordable housing investments through the syndication of investment funds to third parties. Regions transfers the primary benefits of the investment to the customer and recognizes syndication revenue on the closing date of the transaction. Bank-Owned Life Insurance Bank-owned life insurance income primarily represents income earned from the appreciation of the cash surrender value of insurance contracts held and the proceeds of insurance benefits. Regions recognizes revenue each period in the amount of the appreciation of the cash surrender value of the insurance policies. Revenue from the proceeds of insurance benefits is recognized at the time a claim is confirmed. Commercial Credit Fee Income Commercial credit fee income includes letters of credit fees and unused commercial commitment fees. Regions recognizes revenue for letters of credit fees and unused commercial commitment fees over time. Investment Services Fee Income Investment services fee income represents income earned from investment advisory services. Through the use of third party carriers, Regions provides its customers with access to investment products that meet customers’ financial needs and investment objectives. Upon selection of an investment product, the customer enters into a policy with the carrier. Regions’ performance obligation is satisfied by fulfilling its responsibility to place customers in investment vehicles for which Regions earns commissions from the carrier based on agreed-upon fee percentages. In addition, Regions has a contractual relationship with a third party broker dealer to provide full service brokerage and investment advisory activities. As the principal in the arrangement, Regions recognizes the investment services commissions on a gross basis. Securities Gains (Losses), Net Net securities gains or losses result from Regions’ asset/liability management process. Gains or losses on the sale of securities are recognized as each sales transaction occurs with the cost of securities sold based on the specific identification method. Market Value Adjustments on Employee Benefit Assets Regions holds assets for certain employee benefit assets, both defined and other. Those assets are recorded at estimated fair value and the market value variations are recognized each period. Other Miscellaneous Income
Earnings Per Share, Policy [Policy Text Block]	PER SHARE AMOUNTSEarnings per common share is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings per common share is calculated by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the period, plus the effect of restricted and performance stock awards, and in periods prior to 2021, outstanding stock options, if dilutive. Refer to Note 15 for additional information
Fair Value of Financial Instruments, Policy [Policy Text Block]	FAIR VALUE MEASUREMENTS Fair value guidance establishes a framework for using fair value to measure assets and liabilities and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) as opposed to the price that would be paid to acquire the asset or received to assume the liability (an entry price). A fair value measure should reflect the assumptions that market participants would use in pricing the asset or liability, including the assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Required disclosures include stratification of balance sheet amounts measured at fair value based on inputs the Company uses to derive fair value measurements. These strata include: • Level 1 valuations, where the valuation is based on quoted market prices for identical assets or liabilities traded in active markets (which include exchanges and over-the-counter markets with sufficient volume), • Level 2 valuations, where the valuation is based on quoted market prices for similar instruments traded in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market, and • Level 3 valuations, where the valuation is generated from model-based techniques that use significant assumptions not observable in the market, but observable based on Company-specific data. These unobservable assumptions reflect the Company’s own estimates for assumptions that market participants would use in pricing the asset or liability. Valuation techniques typically include option pricing models, discounted cash flow models and similar techniques, but may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. ITEMS MEASURED AT FAIR VALUE ON A RECURRING BASIS Debt securities available for sale, certain mortgage loans held for sale, marketable equity securities, residential MSRs, derivative assets and derivative liabilities are recorded at fair value on a recurring basis. Below is a description of valuation methodologies for these assets and liabilities. Debt securities available for sale consist of U.S. Treasuries, obligations of states and political subdivisions, mortgage-backed securities (including agency securities), and other debt securities. • U.S. Treasuries are valued based on quoted market prices of identical assets on active exchanges. Pricing received for U.S. Treasuries from third-party services is based on a market approach using dealer quotes from multiple active market makers and real-time trading systems. These valuations are Level 1 measurements. • Mortgage-backed securities are valued primarily using data from third-party pricing services for similar securities as applicable. Pricing from these third-party services is generally based on a market approach using observable inputs such as benchmark yields, reported trades, broker/dealer quotes, benchmark securities, TBA prices, issuer spreads, bids and offers, monthly payment information, and collateral performance, as applicable. These valuations are Level 2 measurements. Where such comparable data is not available, the Company develops valuations based on assumptions that are not readily observable in the market place; these valuations are Level 3 measurements. • Obligations of states and political subdivisions are generally based on data from third-party pricing services. The valuations are based on a market approach using observable inputs such as benchmark yields, relevant trade data, material event notices and new issue data. These valuations are Level 2 measurements. • Other debt securities are valued based on Level 1, 2 and 3 measurements, depending on pricing methodology selected and are valued primarily using data from third-party pricing services. Pricing from these third-party services is generally based on a market approach using observable inputs such as benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids and offers, and TRACE reported trades. The majority of Regions' debt securities available for sale are valued using third-party pricing services. To validate pricing related to liquid investment securities, which represent the vast majority of the available for sale portfolio (e.g., mortgage-backed securities), Regions compares price changes received from the third-party pricing service to overall changes in market factors in order to validate the pricing received. To validate pricing received on less liquid investment securities in the available for sale portfolio, Regions receives pricing from third-party brokers-dealers on a sample of securities that are then compared to the pricing received. The pricing service uses standard observable inputs when available, for example: benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, and bids and offers, among others. For certain security types, additional inputs may be used, or some inputs may not be applicable. It is not customary for Regions to adjust the pricing received for the available for sale portfolio. In the event that prices are adjusted, Regions classifies the measurement as a Level 3 measurement. Mortgage loans held for sale consist of residential first mortgage loans and commercial mortgages held for sale. Regions has elected to measure certain residential and commercial mortgage loans held for sale at fair value by applying the fair value option (see additional discussion under the “Fair Value Option” section in Note 21). The residential first mortgage loans held for sale are valued based on traded market prices of similar assets where available and/or discounted cash flows at market interest rates, adjusted for securitization activities that include servicing value and market conditions, a Level 2 measurement. The commercial mortgage loans held for sale are valued based on traded market prices for comparable commercial mortgage-backed securitizations, into which the loans will be placed, adjusted for movements of interest rates and credit spreads, a Level 3 measurement due to the unobservable inputs included in the credit spreads for bonds in commercial mortgage-backed securitizations. Marketable equity securities, which primarily consist of assets held for certain employee benefits and money market funds, are valued based on quoted market prices of identical assets on active exchanges; these valuations are Level 1 measurements. Residential mortgage servicing rights are valued using an option-adjusted spread valuation approach, a Level 3 measurement. The underlying assumptions and estimated values are corroborated at least quarterly by values received from independent third parties. See Note 6 for information regarding the servicing of financial assets and additional details regarding the assumptions relevant to this valuation. Derivative assets and liabilities, which primarily consist of interest rate, foreign exchange, and commodity contracts that include forwards, futures, options and swaps, are included in other assets and other liabilities (as applicable) on the consolidated balance sheets. Interest rate swaps are predominantly traded in over-the-counter markets and, as such, values are determined using widely accepted discounted cash flow models, which are Level 2 measurements. These discounted cash flow models use projections of future cash payments/receipts that are discounted at an appropriate index rate. Regions utilizes forward curves as fair value measurement inputs for the valuation of interest rate and commodity derivatives. The projected future cash flows are sourced from an assumed yield curve, which is consistent with industry standards and conventions. These valuations are adjusted for the unsecured credit risk at the reporting date, which considers collateral posted and the impact of master netting agreements. For options and futures contracts traded in over-the-counter markets, values are determined using discounted cash flow analyses and option pricing models based on market rates and volatilities, which are Level 2 measurements. Interest rate lock commitments on loans intended for sale and risk participations categorized as credit derivatives are valued using option pricing models that incorporate significant unobservable inputs, and therefore are Level 3 measurements. ITEMS MEASURED AT FAIR VALUE ON A NON-RECURRING BASIS From time to time, certain assets may be recorded at fair value on a non-recurring basis. These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. In periods where there is no adjustment, the asset is generally not considered to be at fair value. The following is a description of the valuation methodologies used for assets measured at fair value on a non-recurring basis. Foreclosed property and other real estate is carried in other assets at the lower of the recorded investment in the loan or fair value less estimated costs to sell the property. The fair value for foreclosed property that is based on either observable transactions of similar instruments or formally committed sale prices is classified as a Level 2 measurement. If no formally committed sale price is available, Regions also obtains valuations from professional valuation experts and/or third party appraisers. Updated valuations are obtained on at least an annual basis. Foreclosed property exceeding established dollar thresholds is valued based on appraisals. Appraisals are performed by third-parties with appropriate professional certifications and conform to generally accepted appraisal standards as evidenced by the Uniform Standards of Professional Appraisal Practice. Regions’ policies related to appraisals conform to regulations established by the Financial Institutions Reform, Recovery and Enforcement Act of 1989 and other regulatory guidance. Professional valuations are considered Level 2 measurements because they are based largely on observable inputs. Regions has a centralized appraisal review function that is responsible for reviewing appraisals for compliance with banking regulations and guidelines as well as appraisal standards. Based on these reviews, Regions may make adjustments to the market value conclusions determined in the appraisals of real estate (either as other real estate or loans held for sale) when the appraisal review function determines that the valuation is based on inappropriate assumptions or where the conclusion is not sufficiently supported by the market data presented in the appraisal. Adjustments to the market value conclusions are discussed with the professional valuation experts and/or third-party appraisers; the magnitude of the adjustments that are not mutually agreed upon is insignificant. Adjustments, if made, must be based on sufficient information available to support an alternate opinion of market value. An estimated standard discount factor, which is updated at least annually, is applied to the appraisal amount for certain commercial and investor real estate properties when the recorded investment in the loan is transferred into foreclosed property. Internally adjusted valuations are considered Level 3 measurements as management uses assumptions that may not be observable in the market. These non-recurring fair value measurements are typically recorded on the date an updated offered quote, appraisal, or third-party valuation is received. Equity investments without a readily determinable fair value are adjusted prospectively to estimated fair value when an observable price transaction for a same or similar investment with the same issuer occurs; these valuations are Level 3 measurements. Loans held for sale for which the fair value option has not been elected are recorded at the lower of cost or fair value and therefore may be reported at fair value on a non-recurring basis. The fair values for commercial loans held for sale are based on Company-specific data not observable in the market. These valuations are Level 3 measurements. FAIR VALUE OF FINANCIAL INSTRUMENTS The following methods and assumptions were used by the Company in estimating fair values of financial instruments that are not disclosed above: Cash and cash equivalents : The carrying amounts reported in the consolidated balance sheets and statements of cash flows approximate the estimated fair values. Because these amounts generally relate to either currency or highly liquid assets, these are considered Level 1 valuations. Debt securities held to maturity : The fair values of debt securities held to maturity are estimated in the same manner as the corresponding debt securities available for sale, which are measured at fair value on a recurring basis. Loans (excluding sales-type, direct financing, and leveraged leases), net of unearned income and allowance for loan losses : A discounted cash flow method under the income approach is utilized to estimate the fair value of the loan portfolio. The discounted cash flow method relies upon assumptions about the amount and timing of scheduled principal and interest payments, principal prepayments, and current market rates. The loan portfolio is aggregated into categories based on loan type and credit quality. For each loan category, weighted average statistics, such as coupon rate, age, and remaining term are calculated. These are Level 3 valuations. Other earning assets (excluding equity investments and operating leases) : The carrying amounts reported in the consolidated balance sheets approximate the estimated fair values. While these instruments are not actively traded in the market, the majority of the inputs required to value them are actively quoted and can be validated through external sources. Accordingly, these are Level 2 valuations. The fair values of certain other earning assets are estimated using quoted market prices of identical instruments in active markets and are considered Level 1 measurements. Deposits : The fair value of non-interest-bearing demand accounts, interest-bearing transaction accounts, savings accounts, money market accounts and certain other time deposit accounts is the amount payable on demand at the reporting date (i.e., the carrying amount). Fair values for certificates of deposit are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates, and are considered Level 2 valuations. Long-term borrowings : The fair values of certain long term borrowings are estimated using quoted market prices of identical instruments in non-active markets and are considered Level 2 valuations. Otherwise, valuations are based on non-binding broker quotes and are considered Level 3 valuations. Loan commitments and letters of credit : The fair value of these instruments is reasonably estimated by the carrying value of deferred fees plus the unfunded loan commitments reserve related to the creditworthiness of the counterparty. Because the valuation inputs are not observable in the market and are considered Company specific, these are Level 3 valuations.
New Accounting Pronouncements, Policy [Policy Text Block]	RECENT ACCOUNTING PRONOUNCEMENTS The following table provides a brief description of accounting standards adopted in 2022 and those that could have a material impact to Regions’ consolidated financial statements upon adoption in the future. Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Adopted (or partially adopted) in 2022 ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging— Contracts in Entity’s Own Equity This Update simplifies accounting for convertible instruments by removing certain separation models. Additionally, it revises and clarifies guidance on the derivatives scope exception to make the exception easier to apply. January 1, 2022 The adoption of this guidance did not have a material impact. ASU 2021-04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) This Update clarifies how an issuer should account for modifications made to equity-classified written call options (i.e. a warrant to purchase the issuer’s common stock). The guidance in the Update requires the issuer to treat a modification of an equity-classified warrant that does not cause the warrant to become liability-classified as an exchange of the original warrant for a new warrant. This guidance applies whether the modification is structured as an amendment to the terms and conditions of the warrant or as termination of the original warrant and issuance of a new warrant. January 1, 2022 The adoption of this guidance did not have a material impact. ASU 2021-05 Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments This Update amends the lessor lease classification guidance under ASC 842. Under the amendments, a lessor must classify a lease that includes variable lease payments that do not depend on an index or rate as an operating lease if it would otherwise be classified as a sales-type or direct financing lease and would result in the recognition of a loss at a lease commencement. The amendments address concerns raised during the FASB’s post implementation review regarding recognition of an immediate loss for these leases, as would otherwise be required. January 1, 2022 The adoption of this guidance did not have a material impact. ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers The amendments in this Update require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers, rather than using fair value. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. January 1, 2023 The early adoption of this guidance did not have a material impact. Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Adopted (or partially adopted) in 2022 (continued) ASU 2022-01—Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method This Update represents the final amended guidance to the ‘last-of-layer’ hedge model for fair value hedge relationships. The last-of-layer method allowed for essentially a single hedge for a given portfolio of only prepayable assets. The ‘portfolio layer’ method will make the hedging asset side of the balance sheet easier as it allows for more flexibility in the use of derivatives and structures that best align with management's objectives for hedging purposes. Multiple hedged layers are permitted in fair value hedge relationships for a closed portfolio of financial assets. Both prepayable and non-prepayable financial instruments may be used and included. The Update permits reclassification of debt securities from held-to-maturity to available-for-sale upon adoption with restrictions. Portfolio layer method hedging must be applied to those debt securities. Also, the decision to reclassify must be within 30 days after the date of adoption, and securities would need to be included in a closed portfolio that is designed in a portfolio layer method hedge within that 30-day period. January 1, 2023 The early adoption of this guidance did not have a material impact. ASU 2022-06— Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 This Update defers the sunset date for applying reference rate reform relief in Topic 848 to December 31, 2024 from December 31, 2022. Effective upon issuance The adoption of this guidance did not have a material impact. Standard Description Required Date of Adoption Effect on Regions' financial statements or other significant matters Standards Not Yet Adopted ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures This Update is intended to improve the decision usefulness of information provided to investors about certain loan refinancings, restructurings, and write-offs. The amendments in the Update eliminate the accounting guidance for TDRs by creditors that have adopted CECL while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. The Update also requires that a public business entity disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases. The amendments in this Update should be applied prospectively, except for the transition method related to the recognition and measurement of TDRs for which there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. January 1, 2023 Regions adopted this guidance as of January 1, 2023 with no material impact. 2022-03, Fair Value Measurement of This Update clarifies how the fair value of equity securities subject to contractual sale restrictions is determined. ASU 2022-03 clarifies that a contractual sale restriction should not be considered in measuring fair value. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. January 1, 2023 Regions adopted this guidance as of January 1, 2023 with no material impact.

(2) Additions represent originations after the initial fourth quarter 2021 acquisition of commercial mortgage loans held for sale. RECURRING FAIR VALUE MEASUREMENTS USING SIGNIFICANT UNOBSERVABLE INPUTS Residential mortgage servicing rights The significant unobservable inputs used in the fair value measurement of residential MSRs are OAS and CPR. This valuation requires generating cash f low projections over multiple interest rate scenarios and discounting those cash flows at a risk-adjusted rate. Additionally, the impact of prepayments and changes in the OAS are based on a variety of underlying inputs including servicing costs. Increases or decreases to the underlying cash flow inputs will have a corresponding impact on the value of the MSR asset. The net change in unrealized gains (losses) included in earnings related to MSRs held at period end are disclosed as the changes in valuation inputs or assumptions included in the MSR rollforward table in Note 6. Commercial mortgage loans held for sal e The significant unobservable inputs used in the fair value measurement of commercial mortgage loans held for sale are credit spreads for bonds in commercial mortgage-backed securitization. Commercial mortgage loans held for sale are valued based on traded market prices for comparable commercial mortgage-backed securitizations, into which the loans will be placed, adjusted for movements of interest rates and credit spreads. Increases or decreases in credit spreads would result in an inverse impact to fair value.

Schedule Of Carrying Amounts And Estimated Fair Values Of Financial Instruments	The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company’s financial instruments as of December 31, 2022 are as follows: 2022 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 11,227 $ 11,227 $ 11,227 $ — $ — Debt securities held to maturity 801 751 — 751 — Debt securities available for sale 27,933 27,933 1,187 26,744 2 Loans held for sale 354 354 — 335 19 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 94,044 89,540 — — 89,540 Other earning assets 1,308 1,308 529 779 — Derivative assets 2,609 2,609 3 2,603 3 Financial liabilities: Derivative liabilities 3,378 3,378 2 3,375 1 Deposits (4) 131,743 131,668 — 131,668 — Long-term borrowings 2,284 2,376 — 2,375 1 Loan commitments and letters of credit 153 153 — — 153 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value discount on the loan portfolio's net carrying amount at December 31, 2022 was $4.5 billion or 4.8 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.5 billion at December 31, 2022. (4) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, money market accounts and certain other time deposit accounts is the amount payable on demand at the reporting date (i.e., the carrying amount). Fair values for certificates of deposit are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates. The carrying amounts and estimated fair values, as well as the level within the fair value hierarchy, of the Company's financial instruments as of December 31, 2021 are as follows: 2021 Carrying Estimated Fair Value (1) Level 1 Level 2 Level 3 (In millions) Financial assets: Cash and cash equivalents $ 29,411 $ 29,411 $ 29,411 $ — $ — Debt securities held to maturity 899 950 — 950 — Debt securities available for sale 28,481 28,481 1,132 27,347 2 Loans held for sale 1,003 1,003 — 899 104 Loans (excluding leases), net of unearned income and allowance for loan losses (2)(3) 84,866 85,086 — — 85,086 Other earning assets (4) 1,104 1,104 464 640 — Derivative assets 1,111 1,111 — 1,098 13 Financial liabilities: Derivative liabilities 1,012 1,012 — 1,009 3 Deposits (5) 139,072 139,101 — 139,101 — Long-term borrowings 2,407 2,847 — 2,845 2 Loan commitments and letters of credit 123 123 — — 123 _________ (1) Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred. (2) The estimated fair value of portfolio loans assumes sale of the loans to a third-party financial investor. Accordingly, the value to the Company if the loans were held to maturity is not reflected in the fair value estimate. The fair value premium on the loan portfolio's net carrying amount at December 31, 2021 was $220 million or 0.3 percent. (3) Excluded from this table is the sales-type, direct financing, and leveraged lease carrying amount of $1.4 billion at December 31, 2021. (4) Excluded from this table is the operating lease carrying amount of $83 million at December 31, 2021. (5) The fair value of non-interest-bearing demand accounts, interest-bearing checking accounts, savings accounts, money market accounts and certain other time deposit accounts is the amount payable on demand at the reporting date (i.e., the carrying amount). Fair values for certificates of deposit are estimated by using discounted cash flow analyses, based on market spreads to benchmark rates.

[1]Derivatives in a gain position are recorded as other assets and derivatives in a loss position are recorded as other liabilities on the consolidated balance sheets.[2]Netting adjustments represent amounts recorded to convert derivative assets and derivative liabilities from a gross basis to a net basis in accordance with applicable accounting guidance. The net basis takes into account the impact of cash collateral received or posted, legally enforceable master netting agreements, and variation margin that allow Regions to settle derivative contracts with the counterparty on a net basis and to offset the net position with the related cash collateral.

[1]Derivatives in a gain position are recorded as other assets and derivatives in a loss position are recorded as other liabilities on the consolidated balance sheets.[2]Estimated fair values are consistent with an exit price concept. The assumptions used to estimate the fair values are intended to approximate those that a market participant would use in a hypothetical orderly transaction. In estimating fair value, the Company makes adjustments for estimated changes in interest rates, market liquidity and credit spreads in the periods they are deemed to have occurred.[3]Estimated fair values are consistent with an exit price concept.
