   Re:   SEC Staff Sarbanes-Oxley Review of Filings by Pioneer Funds

Ladies and Gentlemen:

   This letter is to respond to comments received on September 18, 2023 from
Mr. Chad Eskildsen of the Staff of the Securities and Exchange Commission in
connection with the Staff's review of financial statements and other filings by
the Pioneer Funds listed on Appendix A (the "Funds"). Following are the Staff's
comments and the Funds' responses thereto.

1. Comment:   The Staff noted that Pioneer Strategic Income Fund appears to
              have made a tax return of capital distribution during the fiscal
              year ended September 30, 2022. The Staff requested that the Fund
              confirm that it complied with Section 19(a) of the 1940 Act and
              Rule 19a-1 notice requirements with respect to such return of
              capital. The Staff referred to IM-DCFO 2019-02, the Dear CFO
              Letter dated 11/22/2019, with respect to the Staff's position
              that Section 19(a) requires that distributions made from any
              source other than the Fund's net income be accompanied by
              written statements.

              The Staff also requested that the Fund explain why the Fund
              responded "no" to Item B.23 of Form N-CEN filed for the fiscal
              year ended September 30, 2022 ("During the reporting period, did
              the Registrant pay any dividend or make any distribution in the
              nature of a dividend payment, required to be accompanied by a
              written statement pursuant to Section 19(a) of the [1940 Act]
              and Rule 19a-1 thereunder").

   Response:  Pioneer Strategic Income Fund notes that it did not make any
              distributions that were in excess of its book income during the
              fiscal year ended September 30, 2022. The Fund notes that the
              distribution referenced by the Staff was determined to be a
              return of capital on a tax basis due to tax adjustments after
              the Fund calculated its taxable income for the fiscal year.
              Accordingly, the Fund respectfully submits that (i) a Rule 19a-1
              notice was not required with respect to the tax return of
              capital distribution referenced by the Staff, and (ii) the Fund
              correctly responded "no" to Item B.23 of Form N-CEN filed for
              the fiscal year ended September 30, 2022.

2. Comment:   The Staff noted that Items 4(i) and 4(j) of Form N-CSR,
              regarding Holding Foreign Companies Accountable Act disclosure,
              became effective as of January 10, 2022. The



              Staff requested that the Funds confirm that they will include
              these items, and appropriate responses, in future Form N-CSR
              filings.

   Response:  The Funds confirm that they will include Items 4(i) and 4(j),
              and appropriate responses, in future Form N-CSR filings.

3. Comment:   The Staff noted that the Form N-CEN filed by Pioneer Variable
              Contracts Trust for the fiscal year ended December 31, 2022
              reported in response to Item B.22. that payments were made to
              shareholders or shareholder accounts were reprocessed as a
              result of an error in calculating the net asset value of each of
              Pioneer Bond VCT Portfolio, Pioneer High Yield VCT Portfolio and
              Pioneer Strategic Income VCT Portfolio, but that no
              corresponding disclosure was included in the financial
              statements of such Funds. The Staff requested that the Funds
              describe the nature and circumstances of such NAV errors, any
              associated internal control implications, mitigating actions
              taken with respect to such NAV errors and any internal control
              issues, and amounts reimbursed to shareholders, if any. The
              Staff also requested that, if amounts have been reimbursed to
              shareholders, to please explain why such payments were not
              disclosed in the Funds' financial statements, citing U.S. GAAP.

   Response:  The Funds note that the NAV errors reported in response to Item
              B.22 with respect to Pioneer Bond VCT Portfolio, Pioneer High
              Yield VCT Portfolio and Pioneer Strategic Income VCT Portfolio
              related to incorrect processing of gain/loss information for
              certain credit default swap index (CDX) transactions by such
              Funds.

              The Funds note that the transaction processing system used
              during the fiscal year ended December 31, 2022 by Amundi Asset
              Management US, Inc. ("Amundi US"), the Funds' adviser,
              compressed CDX transactions, collapsing two or more derivative
              trades in the same security with the goal of combining the
              notional outstanding into a single position, for risk management
              purposes. However, it was determined that, as a result of such
              compression trade processing and related adjustments, gain/loss
              amounts with respect to CDX transactions were recorded
              incorrectly during the fiscal year ended December 31, 2022 for
              Pioneer Bond VCT Portfolio, Pioneer High Yield VCT Portfolio and
              Pioneer Strategic Income VCT Portfolio.

              Amundi US identified the issue in January 2023 in connection
              with the audits of the financial statements of certain funds in
              the Pioneer Funds complex. In response to the issue, Amundi US
              implemented a temporary manual process to reclassify unrealized
              and realized gain/loss related to CDX transactions for financial
              reporting purposes. This manual process was effective during the
              audit of the financial statements of each of Pioneer Bond VCT
              Portfolio, Pioneer High Yield VCT Portfolio and Pioneer
              Strategic Income VCT Portfolio for the fiscal year ended
              December 31, 2022, and no internal control deficiency, including
              with respect to CDX transactions, was identified for such Funds
              for the fiscal year ended December 31, 2022. Subsequently, a
              fully automated CDX trade integration process was implemented in
              an effort to mitigate the risk of potential future NAV errors
              and reporting issues.

              As reported in response to Item B.22 of Form N-CEN, it was
              determined that the NAVs of Pioneer Bond VCT Portfolio, Pioneer
              High Yield VCT Portfolio and Pioneer Strategic Income VCT
              Portfolio were misstated for the period between September 30,
              2022 and November 23, 2022. The NAVs reported during the
              misstatement period were subsequently recalculated. It was
              determined that the daily misstatement for each

                                      2



        Fund ranged from $0.02 to $0.04 per share. Amundi US reimbursed
        each Fund as a result of the NAV error, and each Fund then
        reprocessed activity for shareholders who experienced a loss by
        redeeming shares at an incorrect NAV. The total reimbursements
        were calculated on a daily basis for the period noted above, in
        accordance with the Funds' NAV error correction policy. The
        amounts reimbursed were $5,166 to shareholders of Pioneer Bond
        VCT Portfolio (Net Assets at 12/31/22 $142.2m), $11,123 to
        shareholders of Pioneer High Yield VCT Portfolio (Net Assets at
        12/31/22 $27.4m), and $2,107 to shareholders of Pioneer
        Strategic Income VCT Portfolio (Net Assets at 12/31/22 $32.5m).

        The Funds note that the reimbursements discussed
        above were determined and made in February 2023, subsequent to
        the end of the Funds' fiscal year ended December 31, 2022.
        Accordingly, such reimbursements were not disclosed in the
        Funds' financial statements for the fiscal year ended
        December 31, 2022. The Funds confirm that such reimbursements
        will be disclosed in the Funds' audited financial statements for
        the fiscal year ended December 31, 2023 in accordance with the
        guidance in FASB ASC 946-20, and related guidance including
        946-205.

   Please call the undersigned at 617-422-4697 with any questions.

                                                  Sincerely,

                                                  /s/ Anthony J. Koenig, Jr.
