The lower impairment provisioning is primarily driven by the retirement of the customer uncertainty PMA following rebuild of certain CIB models, which better capture the macroeconomic outlook; and a granular assessment of the portfolio, which is subject to increased monitoring under Barclays Risk Management framework. The portfolio also benefits from an external hedge protection program that enables effective risk management against credit losses. An additional £72m (December 2022: £115m) impairment allowance has been provisioned against undrawn commitments not included in the table above. Movement in gross exposures and impairment allowance including provisions for loan commitments and financial guarantees The following tables present a reconciliation of the opening to the closing balance of the exposure and impairment allowance. An explanation of the methodology used to determine credit impairment provisions is included in the Barclays PLC Annual Report 2022. Transfers between stages in the tables have been reflected as if they had taken place at the beginning of the year. 'Net drawdowns, repayments, net re-measurement and movements due to exposure and risk parameter changes' includes additional drawdowns and partial repayments from existing facilities. Additionally, the below tables do not include other financial assets subject to impairment such as cash collateral and settlement balances, financial assets at fair value through other comprehensive income and other assets.

Economic uncertainty adjustments Models have been developed with data from non-inflationary periods establishing a relationship between input variables and customer delinquency based on past behaviour. Additionally, models are trying to interpret significant rates of change in macroeconomic variables and applying these to stable probability of default (PD) levels. As such there is a risk that the modelled output fails to capture the appropriate response to changes in macroeconomic variables including higher interest rates and continuing inflationary stress with modelled impairment provisions impacted by uncertainty. This uncertainty continues to be captured in two ways. Firstly, customer uncertainty: the identification of customers and clients who may be more vulnerable to economic instability; and secondly, model uncertainty: to capture the impact from model limitations and sensitivities to specific macroeconomic parameters which are applied at a portfolio level. Economic uncertainty adjustments have decreased from last year, informed by retirement of all legacy Corporate and Investment Bank (CIB) adjustments following the rebuild of certain CIB models in order to better capture the macroeconomic outlook. Furthermore, adjustments have been re-sized to capture affordability headwinds in UK retail lending considered not adequately captured in modelled outcomes. The balance as at H123 is £271m (FY22: £317m) and includes: Customer and client uncertainty provisions of £221m (FY22: £423m) includes: • Retail mortgages: £22m (FY22: £4m) includes an adjustment applied to customers considered most vulnerable to affordability pressures. The increase is primarily driven by an adjustment introduced to reflect the risk of borrowers refinancing onto higher rates in the medium term. • Retail credit cards: £93m (FY22: £93m) and Retail other: £8m (FY22: £25m) includes an adjustment applied to customers considered most vulnerable to affordability pressures. This adjustment is predominantly held in Stage 2 in line with customer risk profiles. Reduction within Retail other is primarily driven by re-scoping for customers remaining resilient to affordability headwinds. • Corporate loans: £98m (FY22: £301m) includes an adjustment of £86m to reflect possible cross default risk on Barclays’ lending in respect of clients who have taken bounce back loans and £12m for SME exposures considered most at risk from inflationary concerns, supply chain constraints and consumer demand headwinds. The reduction of £(203)m is primarily informed by retirement of adjustment for high risk sectors following a granular credit risk assessment for qualifying exposures, and re-build of certain CIB models which more appropriately capture downside risk. Model uncertainty provisions of £50m (FY22: £(106)m) includes: • Retail credit cards: £50m (FY22: £nil) includes an adjustment to reflect recent changes to certain macroeconomic variables to more appropriately capture the provision impact. • Previously held adjustment of £(106)m within Corporate loans to correct for model oversensitivity has been retired following the re-build of certain CIB models which more appropriately capture the macroeconomic outlook. Other adjustments Other adjustments are operational in nature and are expected to remain in place until they can be reflected in the underlying models. These adjustments result from data limitations and model performance related issues identified through model monitoring and other established governance processes. Other adjustments of £359m (FY22: £208m) includes: • Retail mortgages: £116m (FY22: £85m) primarily include adjustments informed by model monitoring and an adjustment for the definition of default under the Capital Requirements Regulation. The increase is predominantly driven by resizing of model monitoring adjustments. • Retail credit cards: £48m (FY22: £87m) primarily includes an adjustment in the UK for the definition of default under the Capital Requirements Regulation, and an adjustment in the US to the qualitative measures for high-risk account management (HRAM) accounts; partially offset by model monitoring adjustments. The reduction is primarily driven by an adjustment made during the year in the US to limit ECL sensitivity to certain macroeconomic variables partially offset by an adjustment in the UK for recalibration of Loss Given Default (LGD) to reflect revised recovery expectations. • Retail other: £45m (FY22: £99m) primarily includes an adjustment for the definition of default under the Capital Requirements Regulation and adjustments informed by model monitoring. The reduction is primarily driven by operational model adjustments made during the year within Private Banking and Wealth Management. • Corporate loans: £150m (FY22: £(63)m) primarily include adjustments within SME informed by model monitoring and definition of default under the Capital Requirements Regulation. Movement of £213m within Corporate loans is primarily driven by the retirement of all CIB legacy adjustments. Management adjustments held in 2022 primarily comprised of an adjustment to limit ECL sensitivity to the macroeconomic variable for Federal Tax Receipts and model monitoring adjustments, which is no longer needed following the re-build of certain CIB models. Measurement uncertainty Scenarios used to calculate the Group’s ECL charge were refreshed in Q223 with the Baseline scenario reflecting the latest consensus macroeconomic forecasts available at the time of the scenario refresh. In the Baseline scenario, although the outlook in major economies has improved somewhat (since Q422), the full effect of the inflation shock and rising rates is lagged and so contributes to a further squeeze of household finances over the coming quarters, posing downside risks to GDP. UK and US unemployment rates increase only gradually in the coming quarters, peaking at 4.5% in Q424 and 4.7% in Q224 respectively. Central banks continue raising interest rates, with both the UK bank rate and the US federal funds rate peaking at 5.25% during 2023. The Downside 2 scenario is broadly aligned to the previous scenario refresh. Inflation rates rise again as energy prices suddenly surge again amid renewed geopolitical risks. Inflation becomes entrenched and inflation expectations go up, contributing to higher pressure on wage growth. Central banks are forced to raise interest rates sharply with the UK bank rate reaching 8% and the US federal funds rate peaking at 7%. Weakened businesses lay off workers and consumers stop spending exacerbating the downward stress. Unemployment peaks at 8.5% in the UK and 9.8% in the US. Given already stretched valuations, the sharp increase in borrowing costs sees house prices decrease significantly. In the Upside scenarios, lower energy prices add downward pressure on prices globally, while recovering labour force participation limits wage growth. As a result of easing inflation, central banks lower interest rates to support the economic recovery. The methodology for estimating scenario probability weights involves simulating a range of future paths for UK and US GDP using historical data with the five scenarios mapped against the distribution of these future paths. The median is centred around the Baseline with scenarios furth

Disclosure of initial application of standards or interpretations [abstract]
Basis of preparation	Basis of preparation These condensed consolidated interim financial statements ("the financial statements") for the six months ended 30 June 2023 have been prepared in accordance with the Disclosure Guidance and Transparency Rules (DTR) of the UK’s Financial Conduct Authority (FCA), and IAS 34, Interim Financial Reporting, as published by the International Accounting Standards Board (IASB) and adopted by the UK. The condensed consolidated interim financial statements should be read in conjunction with the annual financial statements for the year ended 31 December 2022. The annual financial statements for the year ended 31 December 2022 were prepared in accordance with international accounting standards in conformity with the requirements of the Companies Act 2006 and in accordance with International Financial Reporting Standards (IFRS) and interpretations (IFRICs) as issued by the IASB and adopted by the UK. The accounting policies and methods of computation used in these condensed consolidated interim financial statements are the same as those used in the Barclays PLC Annual Report for the financial year ended 31 December 2022. 1. Going concern The financial statements are prepared on a going concern basis, as the Directors are satisfied that the Group and parent company have the resources to continue in business for a period of at least 12 months from approval of the interim financial statements. In making this assessment, the Directors have considered a wide range of information relating to present and future conditions and includes a review of a working capital report (WCR). The WCR is used by the Directors to assess the future performance of the business and that it has the resources in place that are required to meet its ongoing regulatory requirements. The WCR also includes an assessment of the impact of internally generated stress testing scenarios on the liquidity and capital requirement forecasts. The stress tests used were based upon an assessment of reasonably possible downside economic scenarios that the Group could experience. The WCR indicated that the Group had sufficient capital in place to support its future business requirements and remained above its regulatory minimum requirements in the internal stress scenarios. 2.

Valuation The following table shows the Group’s assets and liabilities that are held at fair value disaggregated by valuation technique (fair value hierarchy) and balance sheet classification: Valuation technique using Quoted market prices Observable inputs Significant unobservable inputs (Level 1) (Level 2) (Level 3) Total As at 30.06.23 £m £m £m £m Trading portfolio assets 87,003 72,032 6,799 165,834 Financial assets at fair value through the income statement 6,144 219,938 9,018 235,100 Derivative financial instruments 3,484 258,295 4,533 266,312 Financial assets at fair value through other comprehensive income 24,477 41,477 114 66,068 Investment property — — 2 2 Total assets 121,108 591,742 20,466 733,316 Trading portfolio liabilities (37,451) (33,477) (52) (70,980) Financial liabilities designated at fair value (115) (313,439) (1,100) (314,654) Derivative financial instruments (4,064) (245,517) (5,268) (254,849) Total liabilities (41,630) (592,433) (6,420) (640,483) As at 31.12.22 Trading portfolio assets 62,478 64,855 6,480 133,813 Financial assets at fair value through the income statement 5,720 198,723 9,125 213,568 Derivative financial instruments 10,054 287,152 5,174 302,380 Financial assets at fair value through other comprehensive income 20,704 44,347 11 65,062 Investment property — — 5 5 Total assets 98,956 595,077 20,795 714,828 Trading portfolio liabilities (44,128) (28,740) (56) (72,924) Financial liabilities designated at fair value (133) (270,454) (1,050) (271,637) Derivative financial instruments (10,823) (272,434) (6,363) (289,620) Total liabilities (55,084) (571,628) (7,469) (634,181) The following table shows the Group’s Level 3 assets and liabilities that are held at fair value disaggregated by product type: As at 30.06.23 As at 31.12.22 Assets Liabilities Assets Liabilities £m £m £m £m Interest rate derivatives 2,523 (2,043) 2,362 (2,858) Foreign exchange derivatives 182 (177) 1,513 (1,474) Credit derivatives 342 (694) 290 (603) Equity derivatives 1,488 (2,356) 1,009 (1,428) Corporate debt 1,769 (35) 1,677 (49) Reverse repurchase and repurchase agreements 44 (643) 37 (434) Non-asset backed loans 9,631 — 9,949 — Private equity investments 1,280 (8) 1,291 (8) Other 1 3,207 (464) 2,667 (615) Total 20,466 (6,420) 20,795 (7,469) 1 Other includes commercial real estate loans, funds and fund-linked products, asset backed loans, asset backed securities, equity cash products, issued debt, commercial paper, Government and government sponsored debt and investment property. Assets and liabilities reclassified between Level 1 and Level 2 During the period, there were no material transfers between Level 1 and Level 2 (period ended 31 December 2022: no material transfers between Level 1 and Level 2). Level 3 movement analysis The following table summarises the movements in the balances of Level 3 assets and liabilities during the period. The table shows gains and losses and includes amounts for all financial assets and liabilities that are held at fair value transferred to and from Level 3 during the period. Transfers have been reflected as if they had taken place at the beginning of the period. Asset and liability moves between Level 2 and Level 3 are primarily due to i) an increase or decrease in observable market activity related to an input or ii) a change in the significance of the unobservable input, with assets and liabilities classified as Level 3 if an unobservable input is deemed significant.

The sensitivity methodologies applied take account of the nature of valuation techniques used, as well as the availability and reliability of observable proxy and historical data and the impact of using alternative models. Sensitivities are dynamically calculated on a monthly basis. The calculation is based on range or spread data of a reliable reference source or a scenario based on relevant market analysis alongside the impact of using alternative models. Sensitivities are calculated without reflecting the impact of any diversification in the portfolio. Current year valuation and sensitivity methodologies are consistent with those described within Note 17, Fair value of financial instruments in the Barclays PLC Annual Report 2022.

The effect of stressing unobservable inputs to a range of reasonably possible alternatives, alongside considering the impact of using alternative models, would be to increase fair values by up to £1,097m (December 2022: £1,076m) or to decrease fair values by up to £1,523m (December 2022: £1,328m) with substantially all the potential effect impacting profit and loss rather than reserves. Significant unobservable inputs The valuation techniques and significant unobservable inputs for assets and liabilities recognised at fair value and classified as Level 3 are consistent with Note 17, Fair value of financial instruments in the Barclays PLC Annual Report 2022. Fair value adjustments Key balance sheet valuation adjustments are quantified below: As at 30.06.23 As at 31.12.22 £m £m Exit price adjustments derived from market bid-offer spreads (554) (577) Uncollateralised derivative funding (24) (11) Derivative credit valuation adjustments (241) (319) Derivative debit valuation adjustments 196 208 • Exit price adjustments derived from market bid-offer spreads decreased by £23m to £554m • Uncollateralised derivative funding increased by £13m to £24m • Derivative credit valuation adjustments decreased by £78m to £241m as a result of tightening input counterparty credit spreads • Derivative debit valuation adjustments decreased by £12m to £196m Portfolio exemption The Group uses the portfolio exemption in IFRS 13, Fair Value Measurement to measure the fair value of groups of financial assets and liabilities. Instruments are measured using the price that would be received to sell a net long position (i.e. an asset) for a particular risk exposure or to transfer a net short position (i.e. a liability) for a particular risk exposure in an orderly transaction between market participants at the balance sheet date under current market conditions. Accordingly, the Group measures the fair value of the group of financial assets and liabilities consistently with how market participants would price the net risk exposure at the measurement date. Unrecognised gains as a result of the use of valuation models using unobservable inputs The amount that has yet to be recognised in income that relates to the difference between the transaction price (the fair value at initial recognition) and the amount that would have arisen had valuation models using unobservable inputs been used on initial recognition, less amounts subsequently recognised, is £197m (December 2022: £126m) for financial instruments measured at fair value and £209m (December 2022: £216m) for financial instruments carried at amortised cost. There are additions and FX gains of £107m (December 2022: £59m) and amortisation and releases of £36m (December 2022: £66m) for financial instruments measured at fair value and additions of £nil (December 2022: £nil) and amortisation and releases of £7m (December 2022: £14m) for financial instruments carried at amortised cost. Third party credit enhancements Structured and brokered certificates of deposit issued by the Group are insured up to $250,000 per depositor by the Federal Deposit Insurance Corporation (FDIC) in the United States. The FDIC is funded by premiums that Barclays and other banks pay for deposit insurance coverage. The carrying value of these issued certificates of deposit that are designated under the IFRS 9 fair value option includes this third party credit enhancement. The on balance sheet value of these brokered certificates of deposit amounted to £4,648m (December 2022: £5,197m). Comparison of carrying amounts and fair values for assets and liabilities not held at fair value Valuation methodologies employed in calculating the fair value of financial assets and liabilities measured at amortised cost are consistent with those described within Note 17, Fair value of financial instruments in the Barclays PLC Annual Report 2022. The following table summarises the fair value of financial assets and liabilities measured at amortised cost on the Group’s balance sheet.

Intangible assets and goodwill [abstract]
Goodwill and intangible assets	Goodwill and intangible assetsThe Group performed an impairment review to assess the recoverability of its goodwill and intangible asset balances as at 31 December 2022. The outcome of this review is disclosed on pages 473-476 of the Barclays PLC Annual Report 2022. No impairment was recognised as a result of the review as value in use exceeded carrying amount. The increased goodwill in the period is primarily a result of the Kensington Mortgage Company acquisition in March 2023. A review of the Group's goodwill and intangible assets as at 30 June 2023 did not identify any factors indicating impairment. In May 2023, Barclays Bank UK PLC sold the entire issued share capital of Barclays Asset Management Limited and Barclays Investment Solutions Limited along with certain other assets and liabilities, business guarantees and business contracts (together with the transfer of associated employees of Barclays Bank UK PLC) to Barclays Bank PLC. As a result of this transfer, Intangible assets of approximately £0.2bn held within Barclays Execution Services Limited has been allocated from Personal Banking to Private Banking.

Retirement benefits	Retirement benefits As at 30 June 2023, the Group’s IAS 19 net pension surplus across all schemes was £3.9bn (December 2022: £4.5bn). The UK Retirement Fund (UKRF), which is the Group’s main scheme, had an IAS 19 net pension surplus of £4.1bn (December 2022: £4.7bn). The movement for the UKRF was mainly driven by: actual price inflation being higher than assumed, future long-term price inflation expected to be higher than assumed at the start of the year, assets underperforming relative to the discount rate, partially offset by an increase in discount rate. UKRF funding valuations The latest triennial actuarial valuation of the UKRF with an effective date of 30 September 2022 was completed in February 2023. The valuation showed a funding surplus of £2bn (2021 update: £0.6bn surplus). As the UKRF had a funding surplus at the valuation date, the 2023 deficit reduction contribution (£286m), agreed as part of the 2019 triennial actuarial valuation, is no longer required, and no recovery plan is needed.

As at 30 June 2023, there was a cumulative gain of £3,599m (December 2022: £4,772m gain) in the currency translation reserve, a loss during the period of £1,173m. This principally reflects the strengthening of GBP against USD and EUR during the period. Fair value through other comprehensive income reserve The fair value through other comprehensive income reserve represents the total of unrealised gains and losses on fair value through other comprehensive income investments since initial recognition. As at 30 June 2023, there was a cumulative loss of £1,485m (December 2022: £1,560m loss) in the reserve, a gain during the period of £75m. This is principally driven by a gain of £131m from the increase in fair value of bonds (net of hedges) due to decreasing bond yields which was partially offset by a net gain of £25m transferred to the income statement and a tax charge of £31m. Cash flow hedging reserve The cash flow hedging reserve represents the cumulative gains and losses on effective cash flow hedging instruments that will be recycled to the income statement when the hedged transactions affect profit or loss. As at 30 June 2023, there was a cumulative loss of £7,990m (December 2022: £7,235m loss) in the cash flow hedging reserve, a loss during the period of £755m. This principally reflects a £1,793m loss from the fair value movement of interest rate swaps held for hedging purposes as major interest rate forward curves increased offset by £741m of losses transferred to the income statement and a tax credit of £297m. Own credit reserve The own credit reserve reflects the cumulative own credit gains and losses on financial liabilities at fair value. Amounts in the own credit reserve are not recycled to profit or loss in future periods. As at 30 June 2023, there was a cumulative loss of £27m (December 2022: £467m gain) in the own credit reserve, a loss of £494m during the period. This principally reflects a £682m loss from tightening of credit spreads partially offset by tax credit of £188m. Other reserves and treasury shares Other reserves relate to redeemed ordinary and preference shares issued by the Group. Treasury shares relate to Barclays PLC shares held principally in relation to the Group’s various share schemes. As at 30 June 2023, there was a balance of £1,446m (December 2022: £1,364m gain). This principally reflects an increase of £86m due to the repurchase of 343m shares as part of the share buybacks conducted in 2023 offset by a £4m movement in the treasury shares balance held in relatio

Legal, Competition And Regulatory Matters [Abstract]
Legal, competition and regulatory matters	Legal, competition and regulatory matters The Group faces legal, competition and regulatory challenges, many of which are beyond our control. The extent of the impact of these matters cannot always be predicted but may materially impact our operations, financial results, condition and prospects. Matters arising from a set of similar circumstances can give rise to either a contingent liability or a provision, or both, depending on the relevant facts and circumstances. The recognition of provisions in relation to such matters involves critical accounting estimates and judgments in accordance with the relevant accounting policies applicable to Note 12, Provisions. We have not disclosed an estimate of the potential financial impact or effect on the Group of contingent liabilities where it is not currently practicable to do so. Various matters detailed in this note seek damages of an unspecified amount. While certain matters specify the damages claimed, such claimed amounts do not necessarily reflect the Group’s potential financial exposure in respect of those matters. Matters are ordered under headings corresponding to the financial statements in which they are disclosed. 1. Barclays PLC and Barclays Bank PLC Investigations into certain advisory services agreements FCA proceedings In 2008, Barclays Bank PLC and Qatar Holdings LLC entered into two advisory service agreements (the Agreements). The Financial Conduct Authority (FCA) conducted an investigation into whether the Agreements may have related to Barclays PLC’s capital raisings in June and November 2008 (the Capital Raisings) and therefore should have been disclosed in the announcements or public documents relating to the Capital Raisings. In 2013, the FCA issued warning notices (the Warning Notices) finding that Barclays PLC and Barclays Bank PLC acted recklessly and in breach of certain disclosure-related listing rules, and that Barclays PLC was also in breach of Listing Principle 3. The financial penalty provided in the Warning Notices was £50m. Barclays PLC and Barclays Bank PLC contested the findings. In September 2022, the FCA’s Regulatory Decisions Committee (RDC) issued Decision Notices finding that Barclays PLC and Barclays Bank PLC breached certain disclosure-related listing rules. The RDC also found that in relation to the disclosures made in the Capital Raising of November 2008, Barclays PLC and Barclays Bank PLC acted recklessly, and that Barclays PLC breached Listing Principle 3. The RDC upheld the combined penalty of £50m on Barclays PLC and Barclays Bank PLC, the same penalty as in the Warning Notices. Barclays PLC and Barclays Bank PLC have referred the RDC’s findings to the Upper Tribunal for reconsideration. Investigations into LIBOR and other benchmarks and related civil actions Regulators and law enforcement agencies, including certain competition authorities, from a number of governments have conducted investigations relating to Barclays Bank PLC’s involvement in allegedly manipulating certain financial benchmarks, such as LIBOR. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Group and other banks in relation to the alleged manipulation of LIBOR and/or other benchmarks. USD LIBOR civil actions The majority of the USD LIBOR cases, which have been filed in various US jurisdictions, have been consolidated for pre-trial purposes in the US District Court in the Southern District of New York (SDNY). The complaints are substantially similar and allege, among other things, that Barclays PLC, Barclays Bank PLC, Barclays Capital Inc. (BCI) and other financial institutions individually and collectively violated provisions of the US Sherman Antitrust Act (Antitrust Act), the US Commodity Exchange Act (CEA), the US Racketeer Influenced and Corrupt Organizations Act (RICO), the US Securities Exchange Act of 1934 and various state laws by manipulating USD LIBOR rates. Putative class actions and individual actions seek unspecified damages with the exception of one lawsuit, in which the plaintiffs are seeking no less than $100m in actual damages and additional punitive damages against all defendants, including Barclays Bank PLC. Some of the lawsuits also seek trebling of damages under the Antitrust Act and RICO. Barclays Bank PLC has previously settled certain claims. The financial impact of these settlements is not material to the Group’s operating results, cash flows or financial position. Sterling LIBOR civil actions In 2016, two putative class actions filed in the SDNY against Barclays Bank PLC, BCI and other Sterling LIBOR panel banks alleging, among other things, that the defendants manipulated the Sterling LIBOR rate in violation of the Antitrust Act, CEA and RICO, were consolidated. The defendants’ motion to dismiss the claims was granted in 2018. The plaintiffs have appealed the dismissal. Japanese Yen LIBOR civil actions In 2012, a putative class action was filed in the SDNY against Barclays Bank PLC and other Japanese Yen LIBOR panel banks by a lead plaintiff involved in exchange-traded derivatives and members of the Japanese Bankers Association’s Euroyen Tokyo Interbank Offered Rate (Euroyen TIBOR) panel. The complaint alleges, among other things, manipulation of the Euroyen TIBOR and Yen LIBOR rates and breaches of the CEA and the Antitrust Act. In 2014, the court dismissed the plaintiff’s antitrust claims, and, in 2020, the court dismissed the plaintiff’s remaining CEA claims. In 2015, a second putative class action, making similar allegations to the above class action, was filed in the SDNY against Barclays PLC, Barclays Bank PLC and BCI. Barclays and the plaintiffs reached a settlement of $17.75m for both actions, which received final court approval in March 2023. This matter is now concluded. ICE LIBOR civil action In August 2020, an action related to the LIBOR benchmark administered by the Intercontinental Exchange Inc. and certain of its affiliates (ICE) was filed by a group of individual plaintiffs in the US District Court for the Northern District of California on behalf of individual borrowers and consumers of loans and credit cards with variable interest rates linked to USD ICE LIBOR. The plaintiffs’ motion seeking, among other things, preliminary and permanent injunctions to enjoin the defendants from continuing to set LIBOR or enforce any financial instrument that relies in whole or in part on USD LIBOR was denied. The defendants’ motion to dismiss the case was granted in September 2022. The plaintiffs have filed an amended complaint, which the defendants have moved to dismiss. Non-US benchmarks civil actions There remains one claim, issued in 2017, against Barclays Bank PLC and other banks in the UK in connection with alleged manipulation of LIBOR. Proceedings have also been brought in a number of other jurisdictions in Europe, Argentina and Israel relating to alleged manipulation of LIBOR and EURIBOR. Additional proceedings in other jurisdictions may be brought in the future. Credit Default Swap civil action A putative antitrust class action is pending in New Mexico federal court against Barclays Bank PLC, BCI and various other financial institutions. The plaintiffs, the New Mexico State Investment Council and certain New Mexico pension funds, allege that the defendants conspired to manipulate the benchmark price used to value Credit Default Swap (CDS) contracts at settlement (i.e. the CDS final auction price). The plaintiffs allege violations of US antitrust laws and the CEA, and unjust enrichment under state law. The defendants’ motion to dismiss was denied in June 2023. Foreign Exchange investigations and related civil actions The Group has been the subject of investigations in various jurisdictions in relation to certain sales and trading practices in the Foreign Exchange market. Settlements were reached in various jurisdictions in connection with these investigations, including the EU and US. The financial impact of any remaining ongoing investigations is not expected to be material to the Group’s operating results, cash flows or financial position. Various individuals and corporates in a range of jurisdictions have threatened or brought civil actions against the Group and other banks in relation to alleged manipulation of Foreign Exchange markets. US FX opt out civil action In 2018, Barclays Bank PLC and BCI settled a consolidated action filed in the SDNY, alleging manipulation of Foreign Exchange markets (Consolidated FX Action), for a total amount of $384m. Also in 2018, a group of plaintiffs, who opted out of the Consolidated FX Action, filed a complaint in the SDNY against Barclays PLC, Barclays Bank PLC, BCI and other defendants. Some of the plaintiffs’ claims were dismissed in 2020. Barclays PLC, Barclays Bank PLC, and BCI have reached a settlement of all claims against them in the matter. A settlement payment was made in April 2023 and the matter is now concluded. The financial impact of this settlement is not material to the Group’s operating results, cash flows or financial position. US retail basis civil action In 2015, a putative class action was filed against several international banks, including Barclays PLC and BCI, on behalf of a proposed class of individuals who exchanged currencies on a retail basis at bank branches (Retail Basis Claims). The SDNY has ruled that the Retail Basis Claims are not covered by the settlement agreement in the Consolidated FX Action. The Court subsequently dismissed all Retail Basis Claims against the Group and all other defendants. The plaintiffs filed an amended complaint. The defendants’ motion for summary judgment was granted in March 2023, dismissing the plaintiffs’ remaining claims. The plaintiffs are appealing the decision. Non-US FX civil actions Legal proceedings have been brought or are threatened against Barclays PLC, Barclays Bank PLC, BCI and Barclays Execution Services Limited (BX) in connection with alleged manipulation of Foreign Exchange in the UK, a number of other jurisdictions in Europe, Israel, Brazil and Australia. Additional proceedings may be brought in the future. The above-mentioned proceedings include two purported class actions filed against Barclays PLC, Barclays Bank PLC, BX, BCI and other financial institutions in the UK Competition Appeal Tribunal (CAT) in 2019. The CAT refused to certify these claims in the first quarter of 2022. In July 2023, the Court of Appeal overturned the CAT’s decision and found that the claims should be certified on an opt out basis. The Court of Appeal upheld the CAT’s determination as to which of the two purported class representatives should be chosen to bring the claim. Subject to any further appeal, only the claim brought by the chosen class representative will now proceed in the CAT. Also in 2019, a separate claim was filed in the UK in the High Court of Justice (High Court), and subsequently transferred to the CAT, by various banks and asset management firms against Barclays Bank PLC and other financial institutions alleging breaches of European and UK competition laws related to FX trading. This claim has been settled as part of the settlement payment referred to under the US FX opt out civil action above and the matter is now concluded. Metals-related civil actions A US civil complaint alleging manipulation of the price of silver in violation of the CEA, the Antitrust Act and state antitrust and consumer protection laws was brought by a proposed class of plaintiffs against a number of banks, including Barclays Bank PLC, BCI and BX, and transferred to the SDNY. The complaint was dismissed against these Barclays entities and certain other defendants in 2018, and against the remaining defendants in May 2023. The plaintiffs have appealed the dismissal of the complaint against all defendants. Civil actions have also been filed in Canadian courts against Barclays PLC, Barclays Bank PLC, Barclays Capital Canada Inc. and BCI on behalf of proposed classes of plaintiffs alleging manipulation of gold and silver prices. US residential mortgage related civil actions There are two US Residential Mortgage-Backed Securities (RMBS) related civil actions arising from unresolved repurchase requests submitted by Trustees for certain RMBS, alleging breaches of various loan-level representations and warranties (R&Ws) made by Barclays Bank PLC and/or a subsidiary acquired in 2007. In one action, the parties have agreed to settle the litigation. The financial impact of the settlement is not material to the Group’s operating results, cash flows or financial position. The other repurchase action is pending. Government and agency securities civil actions Treasury auction securities civil actions Consolidated putative class action complaints filed in US federal court against Barclays Bank PLC, BCI and other financial institutions under the Antitrust Act and state common law allege that the defendants (i) conspired to manipulate the US Treasury securities market and/or (ii) conspired to prevent the creation of certain platforms by boycotting or threatening to boycott such trading platforms. The court dismissed the consolidated action in March 2021. The plaintiffs filed an amended complaint. The defendants’ motion to dismiss the amended complaint was granted in March 2022. The plaintiffs are appealing this decision. In addition, certain plaintiffs have filed a related, direct action against BCI and certain other financial institutions, alleging that defendants conspired to fix and manipulate the US Treasury securities market in violation of the Antitrust Act, the CEA and state common law. This action remains stayed. Supranational, Sovereign and Agency bonds civil actions Civil antitrust actions have been filed in the SDNY and Federal Court of Canada in Toronto against Barclays Bank PLC, BCI, BX, Barclays Capital Securities Limited and, with respect to the civil action filed in Canada only, Barclays Capital Canada, Inc. and other financial institutions alleging that the defendants conspired to fix prices and restrain competition in the market for US dollar-denominated Supranational, Sovereign and Agency bonds. The SDNY actions were dismissed and these matters are now concluded. In the Federal Court of Canada action, the parties have reached a settlement in principle, which will require court approval. The financial impact of the settlement is not expected to be material to the Group’s operating results, cash flows or financial position. Variable Rate Demand Obligations civil actions Civil actions have been filed against Barclays Bank PLC and BCI and other financial institutions alleging the defendants conspired or colluded to artificially inflate interest rates set for Variable Rate Demand Obligations (VRDOs). VRDOs are municipal bonds with interest rates that reset on a periodic basis, most commonly weekly. Two actions in state court have been filed by private plaintiffs on behalf of the states of Illinois and California. Three putative class action complaints have been consolidated in the SDNY. In the consolidated SDNY class action, certain of the plaintiffs’ claims were dismissed in November 2020 and June 2022 and the plaintiffs’ motion for class certification is pending. In the California action, the California appeals court reversed the dismissal of the plaintiffs’ claims in April 2023. In the Illinois action, the defendants have reached a settlement in principle with the Attorney General for the State of Illinois to resolve the litigation, which is subject to approval by the court. The financial impact of the settlement is not material to the Group’s operating results, cash flows or financial position. Odd-lot corporate bonds antitrust class action In 2020, BCI, together with other financial institutions, were named as defendants in a putative class action. The complaint alleges a conspiracy to boycott developing electronic trading platforms for odd-lots and price fixing. The plaintiffs demand unspecified money damages. The defendants’ motion to dismiss was granted in 2021 and the plaintiffs have appealed the dismissal. Interest rate swap and credit default swap US civil actions Barclays PLC, Barclays Bank PLC and BCI, together with other financial institutions that act as market makers for interest rate swaps (IRS), are named as defendants in several antitrust class actions which were consolidated in the SDNY in 2016. The complaints allege the defendants conspired to prevent the development of exchanges for IRS and demand unspecified money damages. In 2018, trueEX LLC filed an antitrust class action in the SDNY against a number of financial institutions including Barclays PLC, Barclays Bank PLC and BCI based on similar allegations with respect to trueEX LLC’s development of an IRS platform. In 2017, Tera Group Inc. filed a separate civil antitrust action in the SDNY claiming that certain conduct alleged in the IRS cases also caused the plaintiff to suffer harm with respect to the Credit Default Swaps market. In 2018 and 2019, respectively, the court dismissed certain claims in both cases for unjust enrichment and tortious interference but denied motions to dismiss the federal and state antitrust claims, which remain pending. BDC Finance L.L.C. In 2008, BDC Finance L.L.C. (BDC) filed a complaint in the Supreme Court of the State of New York (NY Supreme Court), demanding damages of $298m, alleging that Barclays Bank PLC had breached a contract in connection with a portfolio of total return swaps governed by an ISDA Master Agreement (the Master Agreement). Following a trial, the court ruled in 2018 that Barclays Bank PLC was not a defaulting party, which was affirmed on appeal. In April 2021, the trial court entered judgement in favour of Barclays Bank PLC for $3.3m and as yet to be determined legal fees and costs. BDC appealed. In January 2022, the appellate court reversed the trial court’s summary judgment decision in favour of Barclays Bank PLC and remanded the case to the lower court for further proceedings. The parties have filed cross-motions on the scope of trial. The trial has been adjourned pending a decision on the motions and any subsequent appeal. In 2011, BDC’s investment advisor, BDCM Fund Adviser, LLC and its parent company, Black Diamond Capital Holdings, LLC, also sued Barclays Bank PLC and BCI in Connecticut State Court for unspecified damages allegedly resulting from Barclays Bank PLC’s conduct relating to the Master Agreement, asserting claims for violation of the Connecticut Unfair Trade Practices Act and tortious interference with business and prospective business relations. This case is currently stayed. Civil actions in respect of the US Anti-Terrorism Act There are a number of civil actions, on behalf of more than 4,000 plaintiffs, filed in US federal courts in the US District Court in the Eastern District of New York (EDNY) and SDNY against Barclays Bank PLC and a number of other banks. The complaints generally allege that Barclays Bank PLC and those banks engaged in a conspiracy to facilitate US dollar-denominated transactions for the Iranian Government and various Iranian banks, which in turn funded acts of terrorism that injured or killed the plaintiffs or the plaintiffs’ family members. The plaintiffs seek to recover damages for pain, suffering and mental anguish under the provisions of the US Anti-Terrorism Act, which allow for the trebling of any proven damages. The court granted the defendants’ motions to dismiss three out of the six actions in the EDNY. The plaintiffs appealed in one action and the dismissal was affirmed, and judgment was entered, in January 2023. The court later gave the plaintiffs until December 2023 to make a motion to vacate the judgment. The plaintiffs have also petitioned for US Supreme Court review. In the other two dismissed actions in the EDNY, the court gave plaintiffs until September 2023 to serve amended complaints. This was also the case for the fourth action in the EDNY. Those actions, as well as the two other actions in the EDNY, are currently stayed. Out of the two actions in the SDNY, the court granted the defendants’ motion to dismiss the first action. That action is stayed, and the second SDNY action is stayed pending any appeal on the dismissal of the first. Shareholder derivative action In November 2020, a purported Barclays shareholder filed a putative derivative action in New York state court against BCI and a number of current and former members of the Board of Directors of Barclays PLC and senior executives or employees of the Group. The shareholder filed the claim on behalf of nominal defendant Barclays PLC, alleging that the individual defendants harmed the company through breaches of their duties, including under the Companies Act 2006. The plaintiff seeks damages on behalf of Barclays PLC for the losses that Barclays PLC allegedly suffered as a result of these alleged breaches. An amended complaint was filed in April 2021, which BCI and certain other defendants moved to dismiss. The motion to dismiss was granted in April 2022. The plaintiff appealed the decision, and the dismissal was unanimously affirmed in June 2023 by the First Judicial Department in New York. The plaintiff has sought leave to appeal the First Judicial Department’s decision to the New York Court of Appeals. Derivative transactions civil action In 2021, Vestia, a Dutch housing association, brought a claim against Barclays Bank PLC in the UK in the High Court in relation to a series of derivative transactions entered into with Barclays Bank PLC between 2008 and 2011, seeking damages of £329m. Barclays Bank PLC is defending the claim and has made a counterclaim. Skilled person review in relation to historic timeshare loans and associated matters Clydesdale Financial Services Limited (CFS), which trades as Barclays Partner Finance and houses Barclays’ point-of-sale finance business, was required by the FCA to undertake a skilled person review in 2020 following concerns about historic affordability assessments for certain loans to customers in connection with timeshare purchases. The skilled person review was concluded in 2021. CFS complied fully with the skilled person review requirements, including carrying out certain remediation measures. CFS was not required to conduct a full back book review. Instead, CFS reviewed limited historic lending to ascertain whether its practices caused customer harm and is remediating any examples of harm. This work is expected to be substantially completed during 2023, utilising provisions booked to account for any remediations. Over-issuance of securities in the US In March 2022, executive management became aware that Barclays Bank PLC had issued securities materially in excess of the set amount under its US shelf registration statements. As a result, Barclays Bank PLC commenced a rescission offer on 1 August 2022, by which Barclays Bank PLC offered to repurchase relevant affected securities from certain holders, which expired on 12 September 2022. Further, in September 2022, the SEC announced the resolution of its investigation of Barclays PLC and Barclays Bank PLC relating to such over-issuance of securities. The Group has engaged with, and responded to inquiries and requests for information from, various other regulators who may seek to impose fines, penalties and/or other sanctions as a result of this matter. Furthermore, Barclays Bank PLC and/or its affiliates may incur costs and liabilities in relation to private civil claims which have been filed and may face other potential private civil claims, class actions or other enforcement actions in relation to the over-issuance of securities. By way of example, in September 2022, a purported class action claim was filed in the US District Court in Manhattan seeking to hold Barclays PLC, Barclays Bank PLC and former and current executives responsible for declines in the prices of Barclays PLC’s American depositary receipts, which the plaintiffs claim occurred as a result of alleged misstatements and omissions in its public disclosures. The defendants have moved to dismiss the case. In addition, holders of a series of ETNs have brought claims against Barclays PLC, Barclays Bank PLC, and former and current executives and board members in the US alleging, among other things, that Barclays’ failure to disclose that these ETNs were unregistered securities misled investors and that, as a result, Barclays is liable for the holders’ alleged losses following the suspension of further sales and issuances of such series of ETNs. Two such actions are purported class actions that the plaintiffs have moved to consolidate into a single action in federal court in New York. A contingent liability exists in relation to civil claims or any further enforcement actions taken against Barclays Bank PLC and/or its affiliates, but Barclays Bank PLC is unable to assess the likelihood of liabilities that may arise out of such claims or actions. Any liabilities, claims or actions in connection with the over-issuance of securities under Barclays Bank PLC’s US shelf registration statements could have an adverse effect on the Group’s business, financial condition, results of operations and reputation as a frequent issuer in the securities markets. 2. Barclays PLC, Barclays Bank PLC and Barclays Bank UK PLC HM Revenue & Customs (HMRC) assessments concerning UK Value Added Tax In 2018, HMRC issued notices that have the effect of removing certain overseas subsidiaries that have operations in the UK from Barclays’ UK VAT group, in which group supplies between members are generally free from VAT. The notices have retrospective effect and correspond to assessments of £181m (inclusive of interest), of which Barclays would expect to attribute an amount of approximately £128m to Barclays Bank UK PLC and £53m to Barclays Bank PLC. HMRC’s decision has been appealed to the First Tier Tribunal (Tax Chamber). FCA investigation into transaction monitoring The FCA has been investigating Barclays’ compliance with UK money laundering regulations and the FCA’s rules and Principles for Businesses in an investigation which is focussed on aspects of Barclays’ transaction monitoring in relation to certain business lines now in Barclays Bank UK PLC. Barclays has been co-operating with the investigation and responding to information requests. 3. Barclays PLC Alternative trading systems In 2020, a claim was brought against Barclays PLC in the UK in the High Court by various shareholders regarding Barclays PLC’s share price based on the allegations contained within a complaint by the New York State Attorney General (NYAG) in 2014. Such claim was settled in 2016, as previously disclosed. The more recent claim seeks unquantified damages and Barclays is defending the claim. The NYAG complaint was filed against Barclays PLC and BCI in the NY Supreme Court alleging, among other things, that Barclays PLC and BCI engaged in fraud and deceptive practices in connection with LX, BCI’s SEC-registered alternative trading system. General The Group is engaged in various other legal, competition and regulatory matters in the UK, the US and a number of other overseas jurisdictions. It is subject to legal proceedings brought by and against the Group which arise in the ordinary course of business from time to time, including (but not limited to) disputes in relation to contracts, securities, debt collection, consumer credit, fraud, trusts, client assets, competition, data management and protection, intellectual property, money laundering, financial crime, employment, environmental and other statutory and common law issues. The Group is also subject to enquiries and examinations, requests for information, audits, investigations and legal and other proceedings by regulators, governmental and other public bodies in connection with (but not limited to) consumer protection measures, compliance with legislation and regulation, wholesale trading activity and other areas of banking and business activities in which the Group is or has been engaged. The Group is cooperating with the relevant authorities and keeping all relevant agencies briefed as appropriate in relation to these matters and others described in this note on an ongoing basis. At the present time, Barclays PLC does not expect the ultimate resolution of any of these other matters to have a material adverse effect on the Group’s financial position. However, in light of the uncertainties involved in such matters and the matters specifically described in this note, there can be no assurance that the outcome of a particular matter or matters (including formerly active matters or those matters arising after the date of this note) will not be material to Barclays PLC’s results, operations or cash flows for a particular period, depending on, among other things, the amount of the loss resulting from the matter(s) and the amount of profit otherwise reported for the reporting period.

Interest rate benchmark reform

Interest Rate Benchmark Reform [Abstract]
Interest rate benchmark reform	Interest rate benchmark reform Following the financial crisis, the reform and replacement of benchmark interest rates such as LIBOR became a priority for global regulators. The FCA and other global regulators instructed market participants to prepare for the cessation of most LIBOR rates after the end of 2021, and to adopt “Risk Free Rates” (RFRs). Barclays established a Group-wide LIBOR Transition Programme, which aims to drive strategic execution and identify, manage and resolve keys risks and issues as they arise. Whilst EUR and CHF LIBOR ceased to be published after 31 December 2021, a synthetic version of GBP and JPY LIBOR was made available for certain tenors for a limited period of time to mitigate the risk of widespread disruption to legacy contracts which had not transitioned by end-2021. • Synthetic JPY LIBOR tenors ceased permanently at the end of 2022 in line with an announcement made by the FCA on 29 September 2022. • 1- and 6-month synthetic GBP LIBOR tenors ceased permanently after 31 March 2023 in line with the announcement made by the FCA on 29 September 2022. • 3-month synthetic GBP LIBOR remains available until 31 March 2024 as per an announcement made by the FCA on 23 November 2022. In addition, GBP LIBOR ICE Swap Rate and JPY LIBOR Tokyo Swap Rate ceased to be published at the end of 2021. All of the Group’s exposure to JPY LIBOR and JPY LIBOR Tokyo Swap Rate and to 1- and 6-month GBP LIBOR have now been remediated with only residual exposure remaining to 3-month synthetic GBP LIBOR and GBP LIBOR ICE Swap Rate. For USD LIBOR, certain actively used tenors continued to be published after 2021. However, in line with the US banking regulators’ joint statement, the Group ceased issuing or entering into new contracts that use USD LIBOR as a reference rate from 31 December 2021, other than in relation to those allowable use cases set out under the FCA’s prohibition notice (ref 21A). The overnight and 12-month USD LIBOR tenors ceased to be published after 30 June 2023, with synthetic versions of the 1-, 3- and 6-month USD LIBOR tenors made available for a limited period of time until 30 September 2024. The synthetic versions are for use in legacy contracts only, to help ensure an orderly wind-down of USD LIBOR, as outlined in a statement made by the FCA on 3 April 2023. In addition, the USD LIBOR ICE Swap Rate ceased to be published at the end of June 2023. During H123, the Barclays Group-wide LIBOR Transition Programme focused on the remediation of its exposure to the benchmarks which ceased at the end of June 2023 . The majority of the Group’s exposure to those rates is now considered remediated contractually via central clearing counterparties (CCP) led conversions for cleared derivatives and actively negotiated conversion or insertion of fallbacks to RFRs for other products. In addition to this, whilst active transition and fallback insertion were attempted in most cases, there were also exposures under certain US law governed contracts which were transitioned pursuant to the US Federal Legislation (the Adjustable Interest Rate (LIBOR) Act) at the end of June 2023. The Group continues to (i) identify, manage and mitigate key risks and issues as they arise, (ii) work with clients and counterparties to remediate any trades which remain on synthetic LIBOR or on the GBP or USD LIBOR ICE Swap Rate and (iii) remain on track to meet the associated industry deadlines.

Analysis of movements in Level 3 assets and liabilities	The following table summarises the movements in the balances of Level 3 assets and liabilities during the period. The table shows gains and losses and includes amounts for all financial assets and liabilities that are held at fair value transferred to and from Level 3 during the period. Transfers have been reflected as if they had taken place at the beginning of the period. Asset and liability moves between Level 2 and Level 3 are primarily due to i) an increase or decrease in observable market activity related to an input or ii) a change in the significance of the unobservable input, with assets and liabilities classified as Level 3 if an unobservable input is deemed significant.
