Background Information

Background Information [Abstract]
Nature of Operations [Text Block]	Background Information The Federal Home Loan Bank of Des Moines (the Bank) is a federally chartered corporation that is exempt from all federal, state, and local taxation (except real property taxes and certain employer taxes) and is one of 11 district Federal Home Loan Banks (FHLBanks). The FHLBanks are government-sponsored enterprises (GSEs) and were created under the authority of the Federal Home Loan Bank Act of 1932 (FHLBank Act) in order to serve the public by enhancing the availability of funds for residential mortgages and targeted community development. The Bank is regulated by the Federal Housing Finance Agency (Finance Agency). The Bank is a cooperative, meaning it is owned by its customers, whom the Bank calls members. As a condition of membership in the Bank, all members must purchase and maintain capital stock to support business activities with the Bank. In return, the Bank provides a readily available source of funding and liquidity to its member institutions and eligible housing associates in Alaska, Hawaii, Idaho, Iowa, Minnesota, Missouri, Montana, North Dakota, Oregon, South Dakota, Utah, Washington, Wyoming, and the U.S. Pacific territories of American Samoa, Guam, and the Commonwealth of the Northern Mariana Islands. Commercial banks, savings institutions, credit unions, insurance companies, and community development financial institutions (CDFIs) may apply for membership. State and local housing associates that meet certain statutory criteria may also borrow from the Bank; while eligible to borrow, housing associates are not members of the Bank and, as such, are not permitted to hold capital stock. All stockholders, including current and former members, may receive dividends on their capital stock investment to the extent declared by the Bank’s Board of Directors.

Accounting Policies [Abstract]
Basis of Presentation [Text Block]	Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information. Accordingly, they do not include all of the disclosures required by GAAP for annual financial statements and should be read in conjunction with the audited financial statements for the year ended December 31, 2022, which are contained in the Bank’s 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on March 8, 2023 (2022 Form 10-K). In the opinion of management, the unaudited interim financial information is complete and reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of results for the interim periods. The preparation of financial statements in accordance with GAAP requires management to make assumptions and estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year ending December 31, 2023. SIGNIFICANT ACCOUNTING POLICIES There have been no material changes to the Bank’s significant accounting policies during the six months ended June 30, 2023. Descriptions of all significant accounting policies are included in “Item 8. Financial Statements and Supplementary Data — Note 1 — Summary of Significant Accounting Policies” in the 2022 Form 10-K.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Adopted and Issued Accounting Guidance [Text Block]	Recently Adopted and Issued Accounting Guidance Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) On March 31, 2022, the Financial Accounting Standards Board (FASB) issued guidance eliminating the accounting requirements for troubled debt restructurings (TDRs) by creditors that have adopted the current expected credit losses methodology, while enhancing the disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. Additionally, this guidance requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investment in leases. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2023, and was adopted on a prospective basis. The adoption of this guidance did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. Fair Value Hedging – Portfolio Layer Method (ASU 2022-01) On March 28, 2022, the FASB issued guidance expanding the current last-of-layer method to apply fair value hedging by allowing multiple hedged layers of a single closed portfolio under the method. To reflect that expansion, the last-of-layer method is renamed “the portfolio layer method”. Among other things, this guidance (i) expands the scope of the portfolio layer method to include non-prepayable assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method, and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. This guidance became effective for the interim and annual periods beginning on January 1, 2023. The Bank does not currently utilize the last-of-layer hedging method and therefore this guidance did not have any impact on the Bank’s financial condition, results of operations, or cash flows. Reference Rate Reform (ASU 2020-04) On March 12, 2020, the FASB issued temporary guidance to ease the potential burden in accounting for reference rate reform related to the transition away from the London Interbank Offered Rate (LIBOR). The guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform, if certain criteria are met. These transactions include contract modifications, hedging relationships, and the sale/transfer of held-to-maturity (HTM) debt securities. This guidance became effective immediately and remains in effect until December 31, 2024. As of June 30, 2023, the Bank has transitioned all of its outstanding LIBOR-indexed instruments to reference the Secured Overnight Financing Rate (SOFR) immediately after June 30, 2023, or at the beginning of the next reset period following LIBOR cessation. As a result of finalizing the transition, the Bank elected the contractual modification and hedging relationship optional expedients during the six months ended June 30, 2023. The election of the expedients did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. As all of the Bank’s qualifying contracts have transitioned at June 30, 2023, the Bank does not expect to further elect this guidance through its ending date of December 31, 2024.

Investments

Investments, Debt and Equity Securities [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure [Text Block]	Investments The Bank makes short-term investments in interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold, and makes other investments in debt securities, which are classified as either trading, available-for-sale (AFS), or HTM. INTEREST-BEARING DEPOSITS, SECURITIES PURCHASED UNDER AGREEMENTS TO RESELL, AND FEDERAL FUNDS SOLD The Bank invests in interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold to provide short-term liquidity. These investments are generally transacted with counterparties that have received a credit rating of triple-B or greater (investment grade) by a nationally recognized statistical rating organization (NRSRO). At June 30, 2023 and December 31, 2022, none of these investments were with counterparties rated below triple-B; however, as of June 30, 2023 and December 31, 2022, approximately 20 percent and nine percent were secured securities purchased under agreements to resell with unrated counterparties. These NRSRO ratings may differ from any internal ratings of the investments by the Bank. Federal funds sold are unsecured loans that are generally transacted on an overnight term. Finance Agency regulations include a limit on the amount of unsecured credit the Bank may extend to a counterparty. At June 30, 2023 and December 31, 2022, no allowance for credit losses was recorded for interest-bearing deposits and federal funds sold, as all assets were repaid or expected to be repaid according to their contractual terms. The carrying values of interest-bearing deposits and federal funds sold exclude accrued interest receivable of $15 million and $11 million at June 30, 2023 and December 31, 2022. Securities purchased under agreements to resell are secured, short-term, and are structured such that they are evaluated regularly to determine if the market value of the underlying securities decreases below the market value required as collateral (i.e. subject to collateral maintenance provisions). If so, the counterparty must place an equivalent amount of additional securities as collateral or remit an equivalent amount of cash, generally by the next business day. Based upon the collateral held as security and collateral maintenance provisions with its counterparties, the Bank determined that no allowance for credit losses was needed for its securities purchased under agreements to resell at June 30, 2023 and December 31, 2022. The carrying value of securities purchased under agreements to resell excludes accrued interest receivable of $3 million at both June 30, 2023 and December 31, 2022. DEBT SECURITIES The Bank invests in debt securities, which are classified as either trading, AFS, or HTM. The Bank is prohibited by Finance Agency regulations from purchasing certain higher-risk securities, such as equity securities and debt instruments that are not investment quality. A security is considered to be investment quality if it has adequate financial backing so that full and timely payment of principal and interest is expected and there is minimal risk that the timely payment of principal and interest would not occur because of adverse changes in economic and financial conditions during the projected life of the security. Exceptions are allowed for certain investments targeted at low-income persons or communities, and instruments that experience credit deterioration after their purchase by the Bank.

Other advances may require a prepayment fee or credit that makes the Bank financially indifferent to the prepayment of the advance. At June 30, 2023 and December 31, 2022 , the Bank had callable advances outstanding totaling $16.6 billion and $23.4 billion. The Bank also holds putable advances. With a putable advance, the Bank has the right to terminate the advance from the borrower on predetermined exercise dates. Generally, these put options are exercised when interest rates increase relative to contractual rates. At June 30, 2023 and December 31, 2022, t he Bank had putable advances outstanding totaling $1 million and $168 million. PREPAYMENT FEES The Bank generally charges a prepayment fee for advances that a borrower elects to terminate prior to the stated maturity or outside of a predetermined call or put date. The fees charged are priced to make the Bank financially indifferent to the prepayment of the advance. For certain advances with symmetrical prepayment features, the Bank may charge the borrower a prepayment fee or pay the borrower a prepayment credit, depending on certain circumstances, such as movements in interest rates, when the advance is prepaid. Prepayment fees and credits are recorded net of the hedged item fair value hedging adjustments, if applicable, in advance interest income on the Statements of Income. ADVANCE CONCENTRATIONS The Bank’s advances are primarily concentrated in commercial banks and insurance companies. At June 30, 2023 and December 31, 2022, the Bank had outstanding advances of $24.0 billion and $32.0 billion to Wells Fargo Bank, N.A., which represented 21 percent and 28 percent of the total principal amount of outstanding advances. ALLOWANCE FOR CREDIT LOSSES The Bank evaluates advances for credit losses on a quarterly basis. At June 30, 2023 and December 31, 2022, none of the Bank’s advances were past due, on non-accrual status, or considered impaired. The Bank considers an advance past due if a default of contractual principal or interest exists for a period of 30 days or more. In addition, there were no modifications related to advances resulting from a borrower experiencing financial difficulties during the six months ended June 30, 2023 and 2022.

Receivables [Abstract]
Mortgage Loans Held for Portfolio [Text Block]	Mortgage Loans Held for Portfolio Mortgage loans held for portfolio include conventional mortgage loans and government-guaranteed or -insured mortgage loans obtained primarily through the Mortgage Partnership Finance (MPF) program (Mortgage Partnership Finance and MPF are registered trademarks of the FHLBank of Chicago). The Bank’s mortgage loan program involves investment by the Bank in single-family mortgage loans held for portfolio that are purchased from participating financial institutions (PFIs). Mortgage loans may also be acquired through participations in pools of eligible mortgage loans purchased from other FHLBanks. The Bank’s PFIs generally originate, service, and credit enhance mortgage loans that are sold to the Bank. PFIs participating in the servicing release program do not service the loans owned by the Bank. The servicing on these loans is sold concurrently by the PFI to a designated mortgage service provider. The following table presents information on the Bank’s mortgage loans held for portfolio (dollars in millions): June 30, December 31, 2022 Fixed rate, long-term single-family mortgage loans $ 7,852 $ 7,244 Fixed rate, medium-term 1 single-family mortgage loans 982 1,033 Total unpaid principal balance 8,834 8,277 Premiums 103 96 Discounts (11) (11) Basis adjustments from mortgage loan purchase commitments (11) (9) Total mortgage loans held for portfolio 2 8,915 8,353 Allowance for credit losses (6) (5) Total mortgage loans held for portfolio, net $ 8,909 $ 8,348 1 Medium-term is defined as an original term of 15 years or less. 2 Excludes accrued interest receivable of $46 million and $42 million at June 30, 2023 and December 31, 2022.

Serious delinquency rate on conventional loans was less than one percent at both June 30, 2023 and December 31, 2022. 3 Represents government-insured mortgage loans that are 90 days or more past due. 4 Represents conventional mortgage loans that are 90 days or more past due or for which the collection of interest or principal is doubtful. At June 30, 2023 and December 31, 2022, $25 million and $29 million of conventional mortgage loans on non-accrual status were evaluated individually and did not have a related allowance for credit losses because these loans were either previously charged off to the expected recoverable value and/or the fair value of the underlying collateral was greater than the amortized cost of the loans. ALLOWANCE FOR CREDIT LOSSES The Bank evaluates mortgage loans for credit losses on a quarterly basis. At June 30, 2023 and December 31, 2022, the Bank’s allowance for credit losses on conventional mortgage loans remained stable at $6 million and $5 million. The Bank recorded no credit losses on its government-insured mortgage loans at June 30, 2023 and December 31, 2022. For additional information on the Bank’s allowance methodology, refer to “Item 8.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities [Text Block]	Derivatives and Hedging Activities NATURE OF BUSINESS ACTIVITY The Bank enters into derivative contracts to manage the interest rate risk exposures inherent in its otherwise unhedged assets and funding positions. Finance Agency regulations and the Bank’s risk management policies establish guidelines for derivatives, prohibit trading in or the speculative use of derivatives, and limit credit risk arising from derivatives. For additional information on the Bank’s derivative and hedging accounting policies, see “Item 8. Financial Statements and Supplementary Data — Note 1 — Summary of Significant Accounting Policies” in the 2022 Form 10-K. For additional information on the types of derivatives and hedged items utilized by the Bank, see “Item 8. Financial Statements and Supplementary Data — Note 7 — Derivatives and Hedging Activities” in the 2022 Form 10-K. FINANCIAL STATEMENT EFFECT AND ADDITIONAL FINANCIAL INFORMATION The notional amount of derivatives serves as a factor in determining periodic interest payments and cash flows received and paid. However, the notional amount of derivatives represents neither the actual amounts exchanged nor the overall exposure of the Bank to credit and market risk. The risks of derivatives can be measured meaningfully on a portfolio basis that takes into account the counterparties, the types of derivatives, the items being hedged, and any offsets between the derivatives and the items being hedged. The following table summarizes the Bank’s notional amount and fair value of derivative instruments and total derivative assets and liabilities. Total derivative assets and liabilities include the effect of netting adjustments and cash collateral. For purposes of this disclosure, the derivative values include the fair value of derivatives and the related accrued interest (dollars in millions): June 30, 2023 December 31, 2022 Notional Derivative Derivative Notional Derivative Derivative Derivatives designated as hedging instruments (fair value hedges) Interest rate swaps $ 91,374 $ 200 $ 163 $ 53,136 $ 226 $ 205 Derivatives not designated as hedging instruments (economic hedges) Interest rate swaps 36,214 5 4 48,347 11 13 Forward settlement agreements 235 1 — 46 — — Mortgage loan purchase commitments 231 — 1 46 — — Total derivatives not designated as hedging instruments 36,680 6 5 48,439 11 13 Total derivatives before netting and collateral adjustments $ 128,054 206 168 $ 101,575 237 218 Netting adjustments and cash collateral 1 905 (159) 406 (214) Total derivative assets and derivative liabilities $ 1,111 $ 9 $ 643 $ 4 1 Amounts represent the application of the netting requirements that allow the Bank to net settle positive and negative positions and also cash collateral, including accrued interest, held or placed with the same clearing agent and/or counterparty. At June 30, 2023 and December 31, 2022, cash collateral, including accrued interest, posted by the Bank was $1.2 billion and $739 million. At June 30, 2023 and December 31, 2022, the Bank held cash collateral, including accrued interest, from clearing agents or counterparties of $128 million and $119 million.

The price alignment amount on variation margin for daily settled derivative contracts designated as hedging instruments are recorded in the same line item as the earnings effect of the hedged item. MANAGING CREDIT RISK ON DERIVATIVES The Bank is subject to credit risk due to the risk of nonperformance by counterparties to its derivative contracts. The Bank manages credit risk through credit analyses, collateral requirements, and adherence to the requirements set forth in the Bank’s policies, U.S. Commodity Futures Trading Commission regulations, and Finance Agency regulations. The Bank transacts most of its derivative transactions with large banks and major broker-dealers. Over-the-counter derivative transactions may be either executed directly with a counterparty, referred to as uncleared derivatives, or cleared through a clearing agent with a Clearinghouse, referred to as cleared derivatives. Once a derivative transaction has been accepted for clearing by a Clearinghouse, the derivative transaction is novated and the executing counterparty is replaced with the Clearinghouse. The Bank is not a derivative dealer and does not trade derivatives for short-term profit. For uncleared derivatives, the degree of credit risk is impacted by the extent to which master netting arrangements are included in the derivative contracts to mitigate the risk. The Bank requires collateral agreements on its uncleared derivatives. Certain of the Bank’s uncleared derivative instruments contain provisions that require the Bank to post additional collateral with its counterparties if there is deterioration in the Bank’s credit rating. If the Bank’s credit rating is lowered by an NRSRO, the Bank may be required to deliver additional collateral on uncleared derivative instruments in net liability positions, unless the collateral delivery threshold is set to zero. The Bank had no uncleared derivative instruments with credit-risk-related contingent features that were in a net liability position (before cash collateral and related accrued interest) at June 30, 2023. As such, the Bank was not required to post collateral in the normal course of business. Uncleared derivative transactions executed on or after the dates specified in applicable regulations are subject to two-way initial margin requirements as mandated by the Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, if the Bank’s aggregate uncleared derivative transactions exposure to a counterparty exceeds a specified threshold. The initial margin is required to be held at a third-party custodian and does not change ownership. Rather, the party in respect of which the initial margin has been posted to the third-party custodian will have a security interest in the amount of initial margin required under the uncleared margin rules and can only take ownership upon the occurrence of certain events, including an event of default due to bankruptcy, insolvency, or similar proceeding. As of June 30, 2023, the Bank was not required to post initial margin on its uncleared derivative transactions in accordance with the noted regulations. For all uncleared transactions entered into on or after March 1, 2017, the derivative agreements are fully collateralized with a zero unsecured threshold in accordance with variation margin requirements issued by the U.S. federal bank regulatory agencies and the Commodity Futures Trading Commission. For cleared derivatives, the Clearinghouse is the Bank’s counterparty. The Bank utilizes two Clearinghouses, CME Clearing and London Clearing House (LCH) Ltd., for all cleared derivative transactions. CME Clearing and LCH Ltd. notify the clearing agent of the required initial margin and daily variation margin requirements, and the clearing agent in turn notifies the Bank. Each Clearinghouse determines initial margin requirements which are considered cash collateral. Generally credit ratings are not factored into the initial margin. However, clearing agents may require additional initial margin to be posted based on credit considerations, including, but not limited to, credit rating downgrades. The Bank was not required to post additional initial margin by its clearing agent, based on credit considerations, at June 30, 2023. Variation margin requirements with each Clearinghouse are based on changes in the fair value of cleared derivatives and are legally characterized as daily settlement payments, rather than cash collateral. The requirement that the Bank post initial and variation margin through the clearing agent, to the Clearinghouse, exposes the Bank to institutional credit risk if the clearing agent or the Clearinghouse fails to meet its obligations. The use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties and collateral/payments for changes in the fair value of cleared derivatives is posted daily through a clearing agent. OFFSETTING OF DERIVATIVE ASSETS AND DERIVATIVE LIABILITIES The Bank presents derivative instruments, related cash collateral received or pledged, and associated accrued interest on a net basis by clearing agent and/or by counterparty when it has met the netting requirements. Additional information regarding these agreements is provided in “Item 8. Financial Statements and Supplementary Data — Note 1 — Summary of Significant Accounting Policies” in the 2022 Form 10-K. The Bank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and has determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default, including a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or the clearing agent, or both. Based on this analysis, the Bank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.

Debt Disclosure [Abstract]
Consolidated Obligations [Text Block]	Consolidated Obligations Consolidated obligations consist of bonds and discount notes. The FHLBanks issue consolidated obligations through the Office of Finance as their agent. Bonds are issued primarily to raise intermediate- and long-term funds for the Bank and are not subject to any statutory or regulatory limits on their maturity. Discount notes are issued primarily to raise short-term funds for the Bank and have original maturities of up to one year. Discount notes sell at or below their face amount and are redeemed at par value when they mature. Although the Bank is primarily liable for the portion of consolidated obligations issued on its behalf, it is also jointly and severally liable with the other FHLBanks for the payment of principal and interest on all FHLBank System consolidated obligations. The Finance Agency, at its discretion, may require any FHLBank to make principal and/or interest payments due on any consolidated obligation, whether or not the primary obligor FHLBank has defaulted on the payment of that consolidated obligation. The Finance Agency has never exercised this discretionary authority. At June 30, 2023 and December 31, 2022, the total par value of outstanding consolidated obligations of the FHLBanks was $1,340.2 billion and $1,181.7 billion.

Banking Regulation, Total Capital [Abstract]
Capital [Text Block]	Capital CAPITAL STOCK The Bank’s capital stock has a par value of $100 per share, and all shares are issued, redeemed, and repurchased only at the stated par value. The Bank issues a single class of capital stock (Class B capital stock) and has two subclasses of Class B capital stock: membership and activity-based. Each member must purchase and hold membership capital stock in an amount equal to 0.12 percent of its total assets as of the preceding December 31 st , subject to a cap of $10 million and a floor of $10,000. Each member is also required to purchase activity-based capital stock equal to 4.00 percent of its advances and mortgage loans outstanding on the Bank’s Statements of Condition and 0.10 percent of its standby letters of credit. All capital stock issued is subject to a notice of redemption period of five years. The capital stock requirements established in the Bank’s Capital Plan are designed so that the Bank can remain adequately capitalized as member activity changes. The Bank’s Board of Directors may make adjustments to the capital stock requirements within ranges established in the Capital Plan. EXCESS STOCK Capital stock owned by members in excess of their investment requirement is deemed excess capital stock. Under its Capital Plan, the Bank, at its discretion and upon 15 days written notice, may repurchase excess membership capital stock. The Bank, at its discretion, may also repurchase excess activity-based capital stock to the extent that (i) the excess capital stock balance exceeds an operational threshold set forth in the Capital Plan, which is currently set at zero, or (ii) a member submits a notice to redeem all or a portion of the excess activity-based capital stock. At June 30, 2023 and December 31, 2022, the Bank had no excess capital stock outstanding. MANDATORILY REDEEMABLE CAPITAL STOCK The Bank reclassifies capital stock subject to redemption from equity to a liability (mandatorily redeemable capital stock or MRCS) at the time shares meet the definition of a mandatorily redeemable financial instrument. This occurs after a member provides written notice of intention to withdraw from membership, becomes ineligible for continuing membership, or attains non-member status by merger or consolidation, charter termination, or other involuntary termination from membership. Dividends on MRCS are classified as interest expense on the Statements of Income. The following table summarizes changes in MRCS (dollars in millions): For the Three Months Ended June 30, For the Six Months Ended June 30, 2023 2022 2023 2022 Balance, beginning of period $ 14 $ 18 $ 15 $ 29 Capital stock reclassified to (from) MRCS, net — 2 — 3 Net payments for repurchases/redemptions of MRCS (1) (3) (2) (15) Balance, end of period $ 13 $ 17 $ 13 $ 17 The following table summarizes the Bank’s MRCS by year of contractual redemption (dollars in millions): Year of Contractual Redemption 1 June 30, December 31, 2022 Due after two years through three years $ 6 $ — Due after three years through four years — 8 Past contractual redemption date due to outstanding activity with the Bank 7 7 Total $ 13 $ 15 1 At the Bank’s election, MRCS may be redeemed prior to the expiration of the five year redemption period that commences on the date of the notice of redemption. RESTRICTED RETAINED EARNINGS The Bank entered into a Joint Capital Enhancement Agreement (JCE Agreement) with all of the other FHLBanks in 2011. The JCE Agreement, as amended, is intended to enhance the capital position of the Bank over time. Under the JCE Agreement, each FHLBank is required to allocate 20 percent of its quarterly net income to a separate restricted retained earnings account until the balance of that account, calculated as of the last day of each calendar quarter, equals at least one percent of its average balance of outstanding consolidated obligations for the calendar quarter. The restricted retained earnings are not available to pay dividends. At June 30, 2023 and December 31, 2022, the Bank’s restricted retained earnings account totaled $791 million and $703 million. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) The following table summarizes changes in accumulated other comprehensive income (loss) (AOCI) (dollars in millions): Net unrealized gains (losses) on AFS securities (Note 3) Pension and postretirement benefits Total AOCI Balance, March 31, 2022 $ 27 $ (6) $ 21 Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities (50) — (50) Net current period other comprehensive income (loss) (50) — (50) Balance, June 30, 2022 $ (23) $ (6) $ (29) Balance, March 31, 2023 $ (181) $ (2) $ (183) Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities 77 — 77 Net actuarial gains (losses) — (1) (1) Net current period other comprehensive income (loss) 77 (1) 76 Balance, June 30, 2023 $ (104) $ (3) $ (107) Balance, December 31, 2021 $ 88 $ (4) $ 84 Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities (111) — (111) Net actuarial gains (losses) — (2) (2) Net current period other comprehensive income (loss) (111) (2) (113) Balance, June 30, 2022 $ (23) $ (6) $ (29) Balance, December 31, 2022 $ (114) $ (3) $ (117) Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities 10 — 10 Net current period other comprehensive income (loss) 10 — 10 Balance, June 30, 2023 $ (104) $ (3) $ (107) REGULATORY CAPITAL REQUIREMENTS The Bank is subject to three regulatory capital requirements: • Risk-based capital . The Bank must maintain at all times permanent capital greater than or equal to the sum of its credit, market, and operational risk capital requirements, all calculated in accordance with Finance Agency regulations. Only permanent capital, defined as the amounts paid-in for Class B capital stock (including MRCS), and retained earnings can satisfy this risk-based capital requirement. • Regulatory capital . The Bank is required to maintain a minimum four percent capital-to-asset ratio, which is defined as total regulatory capital divided by total assets. Total regulatory capital includes Class B stock (including MRCS) and retained earnings. • Leverage capital . The Bank is required to maintain a minimum five percent leverage ratio, which is defined as the sum of permanent capital weighted 1.5 times and nonpermanent capital weighted 1.0 times, divided by total assets. The Bank did not hold any nonpermanent capital at June 30, 2023 and December 31, 2022. In addition to the requirements previously discussed, the Finance Agency Advisory Bulletin on capital stock (the Capital Stock AB) requires each FHLBank to maintain at all times a ratio of at least two percent of capital stock to total assets. For purposes of the Capital Stock AB, capital stock includes MRCS. The capital stock to total assets ratio is measured on a daily average basis at month end. If the Bank’s capital falls below the required levels, the Finance Agency has authority to take actions necessary to return it to levels that it deems to be consistent with safe and sound business operations. The following table shows the Bank’s compliance with the Finance Agency’s regulatory capital requirements (dollars in millions): June 30, 2023 December 31, 2022 Required Actual Required Actual Regulatory capital requirements Risk-based capital $ 1,500 $ 9,316 $ 737 $ 8,883 Regulatory capital $ 7,207 $ 9,316 $ 6,567 $ 8,883 Leverage capital $ 9,009 $ 13,974 $ 8,208 $ 13,323 Capital-to-assets ratio 4.00 % 5.17 % 4.00 % 5.41 % Capital stock-to-assets ratio 2.00 % 3.49 % 2.00 % 3.73 % Leverage ratio 5.00 % 7.76 % 5.00 % 8.12 %

Fair Value Disclosures [Abstract]
Fair Value [Text Block]	Fair Value Fair value amounts are determined by the Bank using available market information and reflect the Bank’s best judgment of appropriate valuation methods. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., exit price). The fair value hierarchy requires an entity to maximize the use of significant observable inputs and minimize the use of significant unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the fair value measurement is determined. This overall level is an indication of market observability of the fair value measurement for the asset or liability. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: • Level 1 Inputs. Quoted prices (unadjusted) for identical assets or liabilities in an active market that the Bank can access on the measurement date. An active market for an asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2 Inputs. Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, (iii) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities), and (iv) market-corroborated inputs. • Level 3 Inputs. Unobservable inputs for the asset or liability. Valuations are derived from techniques that use significant assumptions not observable in the market, which may include pricing models, discounted cash flow models, or similar techniques. The Bank reviews its fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities. The following table summarizes the carrying value, fair value, and fair value hierarchy of the Bank’s financial instruments (dollars in millions). The Bank records trading securities, AFS securities, derivative assets, derivative liabilities, financial instruments held under the fair value option, and certain other assets at fair value on a recurring basis, and on occasion certain impaired mortgage loans held for portfolio on a non-recurring basis. The Bank records all other financial assets and liabilities at amortized cost. The fair values do not represent an estimate of the overall market value of the Bank as a going concern, which would take into account future business opportunities and the net profitability of assets and liabilities.

FAIR VALUE ON A NON-RECURRING BASIS The Bank measures certain impaired mortgage loans held for portfolio at Level 3 fair value on a non-recurring basis. These assets are subject to fair value adjustments in certain circumstances. At both June 30, 2023 and December 31, 2022, impaired mortgage loans held for portfolio recorded at fair value as a result of a non-recurring change in fair value were $1 million. These fair values were as of the date the fair value adjustment was recorded during the six months ended June 30, 2023 and year ended December 31, 2022. FAIR VALUE OPTION The fair value option provides an irrevocable option to elect fair value as an alternative measurement for selected financial assets, financial liabilities, unrecognized firm commitments, and written loan commitments not previously carried at fair value. It requires entities to display the fair value of those assets and liabilities for which it has chosen to use fair value on the face of the Statements of Condition. Fair value is used for both the initial and subsequent measurement of the designated assets, liabilities, and commitments, with the changes in fair value recognized in net income. The Bank elects the fair value option for certain financial instruments when a hedge relationship does not qualify for hedge accounting. These fair value elections are made primarily in an effort to mitigate the potential income statement volatility that can arise when an economic derivative is adjusted for changes in fair value but the related hedged item is not. For financial instruments recorded under the fair value option, the related contractual interest income, interest expense, and the discount amortization on fair value option discount notes are recorded as part of net interest income on the Statements of Income. The remaining changes are recorded as “Net gains (losses) on financial instruments held under fair value option” on the Statements of Income. For the three and six months ended June 30, 2023, the Bank recorded net gains of $4 million and net losses of $61 million on financial instruments held under fair value option (i.e., discount notes) compared to net gains of $77 million and $99 million for the same periods in 2022, and the Bank determined no credit risk adjustments for nonperformance were necessary. In determining that no credit risk adjustments were necessary, the Bank considered the following factors: • The Bank is a federally chartered GSE, and as a result of this status, the Bank’s consolidated obligations have historically received the same credit rating as the government bond credit rating of the United States, even though they are not obligations of the United States and are not guaranteed by the United States. • The Bank is jointly and severally liable with the other FHLBanks for the payment of principal and interest on all consolidated obligations of the FHLBanks. The following tables summarize the difference between the unpaid principal balance and fair value of outstanding instruments for which the fair value option has been elected (dollars in millions): June 30, 2023 Unpaid Principal Balance Fair Value Fair Value Over (Under) Unpaid Principal Discount Notes $ 31,154 $ 30,641 $ (513) December 31, 2022 Unpaid Principal Balance Fair Value Fair Value Over (Under) Unpaid Principal Discount Notes $ 45,244 $ 44,531 $ (713)

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	Commitments and Contingencies Joint and Several Liability . The FHLBanks have joint and several liability for all consolidated obligations issued. Accordingly, if an FHLBank were unable to repay any consolidated obligation for which it is the primary obligor, each of the other FHLBanks could be called upon by the Finance Agency to repay all or part of such obligations. No FHLBank has ever been asked or required to repay the principal or interest on any consolidated obligation on behalf of another FHLBank. A t June 30, 2023 and December 31, 2022, the total par value of outstanding consolidated obligations issued on behalf of other FHLBanks for which the Bank is jointly and severally liable was $1,172.1 billion and $1,027.1 billion. The following table summarizes additional off-balance sheet commitments for the Bank (dollars in millions): June 30, 2023 December 31, 2022 Expire Expire Total Total Standby letters of credit 1,2 $ 7,372 $ 158 $ 7,530 $ 6,566 Standby bond purchase agreements 2 111 625 736 736 Commitments to purchase mortgage loans 231 — 231 46 Commitment to issue bonds 1,110 — 1,110 3,200 Commitments to issue discount notes 65 — 65 202 Commitments to fund advances 2 236 70 306 128 1 Excludes commitments to issue standby letters of credit, when applicable. At both June 30, 2023 and December 31, 2022, the Bank had no commitments to issue standby letters of credit. 2 The Bank has deemed it unnecessary to record any liability for credit losses on these agreements at June 30, 2023 and December 31, 2022. Standby Letters of Credit . The Bank issues standby letters of credit on behalf of its members to support certain obligations of the members to third-party beneficiaries. Standby letters of credit may be offered to assist members and non-member housing associates in facilitating residential housing finance, community lending, and asset-liability management, and to provide liquidity. In particular, members often use standby letters of credit as collateral for deposits from federal and state government agencies. Standby letters of credit are executed with members for a fee. If the Bank is required to make payment for a beneficiary’s draw, the member either reimburses the Bank for the amount drawn or, subject to the Bank’s discretion, the amount drawn may be converted into a collateralized advance to the member. The maturities of standby letters of credit outstanding at June 30, 2023 are currently no later than 2028. The carrying value of guarantees related to standby letters of credit are recorded in “Other liabilities” on the Statements of Condition and amounted to $2 million at both June 30, 2023 and December 31, 2022. The Bank monitors the creditworthiness of its standby letters of credit based on an evaluation of its borrowers. The Bank has established parameters for the measurement, review, classification, and monitoring of credit risk related to these standby letters of credit. All standby letters of credit, similar to advances, are fully collateralized at the time of issuance and subject to member borrowing limits as established by the Bank. Standby Bond Purchase Agreements . The Bank has entered into standby bond purchase agreements with state housing associates within its district pursuant to which, for a fee, it agrees to serve as a standby liquidity provider if required, to purchase and hold the housing associate’s bonds until the designated marketing agent can find a suitable investor or the housing associate repurchases the bonds according to a schedule established by the agreement. Each standby bond purchase agreement includes the provisions under which the Bank would be required to purchase the bonds and typically allows the Bank to terminate the agreement upon the occurrence of a default event of the issuer. At June 30, 2023, the Bank had standby bond purchase agreements with six housing associates. The maturities of standby bond purchase agreements outstanding at June 30, 2023 are currently no later than 2028. During the six months ended June 30, 2023 and 2022, the Bank was not required to purchase any bonds under these agreements. Commitments to Purchase Mortgage Loans . The Bank enters into commitments that unconditionally obligate it to purchase mortgage loans from its members. These commitments are considered derivatives and their estimated fair value at June 30, 2023 and December 31, 2022 is reported in “Note 6 — Derivatives and Hedging Activities” as mortgage loan purchase commitments. Commitments to Issue Consolidated Obligations. The Bank enters into commitments to issue consolidated obligations in the normal course of its business, generally that settle within 30 calendar days. At June 30, 2023, the Bank had commitments to issue $1.1 billion and $65 million of consolidated obligation bonds and discount notes. At December 31, 2022, the Bank had commitments to issue $3.2 billion and $202 million of consolidated obligation bonds and discount notes. Commitments to Fund Advances. The Bank enters into commitments to fund additional advances up to 24 months in the future. At June 30, 2023 and December 31, 2022, the Bank had commitments to fund advances of $306 million and $128 million. Other Commitments. For each MPF master commitment, the Bank’s potential loss exposure prior to the PFI’s credit enhancement obligation is estimated and tracked in a first loss account (FLA). For absorbing certain losses in excess of the FLA, PFIs are paid a credit enhancement fee, a portion of which may be performance-based. To the extent the Bank experiences losses under the FLA, it may be able to recapture performance-based credit enhancement fees paid to the PFI to offset these losses. The FLA balance for all MPF master commitments with a PFI credit enhancement obligation was $168 million and $162 million at June 30, 2023 and December 31, 2022.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information.
New Accounting Pronouncements, Policy	Recently Adopted and Issued Accounting Guidance Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) On March 31, 2022, the Financial Accounting Standards Board (FASB) issued guidance eliminating the accounting requirements for troubled debt restructurings (TDRs) by creditors that have adopted the current expected credit losses methodology, while enhancing the disclosure requirements for certain loan refinancings and restructurings by creditors made to borrowers experiencing financial difficulty. Additionally, this guidance requires disclosure of current-period gross write-offs by year of origination for financing receivables and net investment in leases. This guidance became effective for the Bank for the interim and annual periods beginning on January 1, 2023, and was adopted on a prospective basis. The adoption of this guidance did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. Fair Value Hedging – Portfolio Layer Method (ASU 2022-01) On March 28, 2022, the FASB issued guidance expanding the current last-of-layer method to apply fair value hedging by allowing multiple hedged layers of a single closed portfolio under the method. To reflect that expansion, the last-of-layer method is renamed “the portfolio layer method”. Among other things, this guidance (i) expands the scope of the portfolio layer method to include non-prepayable assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method, and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. This guidance became effective for the interim and annual periods beginning on January 1, 2023. The Bank does not currently utilize the last-of-layer hedging method and therefore this guidance did not have any impact on the Bank’s financial condition, results of operations, or cash flows. Reference Rate Reform (ASU 2020-04) On March 12, 2020, the FASB issued temporary guidance to ease the potential burden in accounting for reference rate reform related to the transition away from the London Interbank Offered Rate (LIBOR). The guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform, if certain criteria are met. These transactions include contract modifications, hedging relationships, and the sale/transfer of held-to-maturity (HTM) debt securities. This guidance became effective immediately and remains in effect until December 31, 2024. As of June 30, 2023, the Bank has transitioned all of its outstanding LIBOR-indexed instruments to reference the Secured Overnight Financing Rate (SOFR) immediately after June 30, 2023, or at the beginning of the next reset period following LIBOR cessation. As a result of finalizing the transition, the Bank elected the contractual modification and hedging relationship optional expedients during the six months ended June 30, 2023. The election of the expedients did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. As all of the Bank’s qualifying contracts have transitioned at June 30, 2023, the Bank does not expect to further elect this guidance through its ending date of December 31, 2024.
Derivatives, Offsetting Fair Value Amounts, Policy	The Bank presents derivative instruments, related cash collateral received or pledged, and associated accrued interest on a net basis by clearing agent and/or by counterparty when it has met the netting requirements. Additional information regarding these agreements is provided in “Item 8. Financial Statements and Supplementary Data — Note 1 — Summary of Significant Accounting Policies” in the 2022 Form 10-K.The Bank has analyzed the enforceability of offsetting rights incorporated in its cleared derivative transactions and has determined that the exercise of those offsetting rights by a non-defaulting party under these transactions should be upheld under applicable law upon an event of default, including a bankruptcy, insolvency, or similar proceeding involving the Clearinghouse or the clearing agent, or both. Based on this analysis, the Bank presents a net derivative receivable or payable for all of its transactions through a particular clearing agent with a particular Clearinghouse.
Advances, Prepayment Fees, Policy	The Bank generally charges a prepayment fee for advances that a borrower elects to terminate prior to the stated maturity or outside of a predetermined call or put date. The fees charged are priced to make the Bank financially indifferent to the prepayment of the advance. For certain advances with symmetrical prepayment features, the Bank may charge the borrower a prepayment fee or pay the borrower a prepayment credit, depending on certain circumstances, such as movements in interest rates, when the advance is prepaid. Prepayment fees and credits are recorded net of the hedged item fair value hedging adjustments, if applicable, in advance interest income on the Statements of Income.
Shares Subject to Mandatory Redemption, Changes in Redemption Value, Policy	The Bank reclassifies capital stock subject to redemption from equity to a liability (mandatorily redeemable capital stock or MRCS) at the time shares meet the definition of a mandatorily redeemable financial instrument. This occurs after a member provides written notice of intention to withdraw from membership, becomes ineligible for continuing membership, or attains non-member status by merger or consolidation, charter termination, or other involuntary termination from membership. Dividends on MRCS are classified as interest expense on the Statements of Income.
Fair Value of Financial Instruments, Policy	Fair value amounts are determined by the Bank using available market information and reflect the Bank’s best judgment of appropriate valuation methods. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., exit price). The fair value hierarchy requires an entity to maximize the use of significant observable inputs and minimize the use of significant unobservable inputs when measuring fair value. The inputs are evaluated and an overall level for the fair value measurement is determined. This overall level is an indication of market observability of the fair value measurement for the asset or liability. The fair value hierarchy prioritizes the inputs used to measure fair value into three broad levels: • Level 1 Inputs. Quoted prices (unadjusted) for identical assets or liabilities in an active market that the Bank can access on the measurement date. An active market for an asset or liability is a market in which the transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. • Level 2 Inputs. Inputs other than quoted prices within Level 1 that are observable inputs for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. Level 2 inputs include the following: (i) quoted prices for similar assets or liabilities in active markets, (ii) quoted prices for identical or similar assets or liabilities in markets that are not active, (iii) inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates and yield curves that are observable at commonly quoted intervals and implied volatilities), and (iv) market-corroborated inputs. • Level 3 Inputs. Unobservable inputs for the asset or liability. Valuations are derived from techniques that use significant assumptions not observable in the market, which may include pricing models, discounted cash flow models, or similar techniques. The Bank reviews its fair value hierarchy classifications on a quarterly basis. Changes in the observability of the valuation inputs may result in a reclassification of certain assets or liabilities.
