Background Information [Abstract]
Nature of Operations [Text Block]	Background Information The Bank is a federally chartered corporation that is exempt from all federal, state, and local taxation (except real property taxes and certain employer payroll taxes) and is one of 11 district FHLBanks. The FHLBanks are GSEs and were created under the authority of the 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 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 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]
Summary of Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies BASIS OF PRESENTATION The Bank prepares its financial statements in accordance with GAAP. SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. The most significant of these estimates include those used in conjunction with fair value estimates. Actual results could significantly differ from these estimates. Fair Value. The fair value amounts, recorded on the Bank’s Statements of Condition and presented in the footnote disclosures, have been determined by the Bank using available market information and management’s best judgment of appropriate valuation methods. Although management uses its best judgment in estimating the fair value of financial instruments, there are inherent limitations in any valuation technique. Therefore, these fair values may not be indicative of the amounts that would have been realized in market transactions at the reporting dates. See “ Note 13 — Fair Value ” for more information. Financial Instruments Meeting Netting Requirements The Bank has certain financial instruments, including derivative instruments and securities purchased under agreements to resell, that may be presented on a net basis when there is a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). The Bank has elected to offset its derivative instruments, related cash collateral, and associated accrued interest when it has met the netting requirements. The net exposure for these financial instruments can change on a daily basis and, therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time when this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the requirements for netting, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in “ Note 7 — Derivatives and Hedging Activities. ” At December 31, 2023 and 2022, the Bank had $11.4 billion and $12.6 billion in securities purchased under agreements to resell. There were no offsetting liabilities related to these securities at December 31, 2023 and 2022. 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. Interest-bearing deposits include deposits held with banks or counterparties that do not meet the definition of a security. The Bank treats securities purchased under agreements to resell as short-term collateralized loans. Federal funds sold consist of short-term, unsecured loans generally transacted by counterparties that are considered investment quality by the Bank. All of these investments provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The Bank uses the collateral maintenance provision practical expedient for securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which the Bank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. See “ Note 4 — Investments ” for details on the allowance methodologies relating to these investments. Debt Securities The Bank classifies investment securities as trading, AFS, or HTM at the date of acquisition. Purchases and sales of investment securities are recorded on a trade date basis. The Bank records interest on investment securities to interest income as earned. The Bank generally amortizes/accretes premiums and discounts on AFS and HTM investment securities to income using the contractual level-yield method (level-yield method). In addition, the Bank uses this method to amortize/accrete fair value hedging adjustments. The level-yield method recognizes the income effects of these adjustments over the contractual life of the securities based on the actual behavior of the underlying assets, including adjustments for actual prepayment activities, and reflects the contractual terms of the securities without regard to changes in estimated prepayments based on assumptions about future borrower behavior. For callable AFS and HTM non-MBS purchased at a premium, the Bank amortizes the premium to the next contractual call date. The Bank computes gains and losses on sales of investment securities using the specific identification method and includes these gains and losses in other income (loss). Trading . Securities classified as trading are carried at fair value and generally entered into for liquidity purposes. In addition, the Bank classifies certain securities as trading that do not qualify for hedge accounting, 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. The Bank records changes in the fair value of these securities through other income (loss) as “Net gains (losses) on trading securities.” The Bank does not participate in speculative trading practices and generally holds these investments until maturity, except to the extent management deems necessary to manage the Bank’s liquidity portfolio. Available-for-Sale. Securities that are not classified as trading or HTM are classified as AFS and carried at fair value. The Bank records changes in the fair value of these securities through AOCI as “Net unrealized gains (losses) on available-for-sale securities.” For AFS securities that have been hedged and qualify as a fair value hedge, the Bank records the portion of the change in the fair value of the security related to the risk being hedged in AFS interest income together with the related change in fair value of the derivative, and records the remainder of the change in fair value through AOCI as “Net unrealized gains (losses) on available-for-sale securities.” The Bank evaluates its individual AFS securities for impairment quarterly by comparing the security’s fair value to its amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. Impairment may exist when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). In assessing whether a credit loss exists on an impaired security, the Bank considers whether there would be a shortfall in receiving all cash flows contractually due. When a shortfall is considered possible, the Bank compares the present value of cash flows to be collected from the security with the amortized cost basis of the security. If the present value of cash flows is less than amortized cost, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance is limited by the amount of the unrealized loss. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. If management intends to sell an impaired security classified as AFS, or more likely than not will be required to sell the security before expected recovery of its amortized cost basis, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in other income (loss). If management does not intend to sell an impaired security classified as AFS and it is not more likely than not that management will be required to sell the debt security, then the credit portion of the difference is recognized as an allowance for credit losses and any remaining difference between the security’s fair value and amortized cost is recorded to “Net unrealized gains (losses) on available-for-sale securities” within AOCI. Held-to-Maturity . Securities that the Bank has both the ability and intent to hold to maturity are classified as HTM and carried at amortized cost, which represents the amount at which an investment is acquired, adjusted for periodic principal repayments, amortization of premiums, and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Certain changes in circumstances may cause the Bank to change its intent to hold a security to maturity without calling into question its intent to hold other debt securities to maturity in the future. Thus, the sale or transfer of a HTM security due to certain changes in circumstances, such as evidence of significant deterioration in the issuer’s creditworthiness or changes in regulatory requirements, is not considered to be inconsistent with its original classification. Other events that are isolated, non-recurring, and unusual for the Bank that could not have been reasonably anticipated may cause the Bank to sell or transfer an HTM security without necessarily calling into question its intent to hold other debt securities to maturity. In addition, the sale of a debt security that meets either of the following two conditions would not be considered inconsistent with the original classification of that security: (i) the sale occurs near enough to its maturity date (for example, within three months of maturity), or call date if exercise of the call is probable, that interest rate risk is substantially eliminated as a pricing factor and the changes in market interest rates would not have a significant effect on the security’s fair value or (ii) the sale occurs after the Bank has already collected a substantial portion (at least 85 percent) of the principal outstanding at acquisition due either to prepayments on the debt security or to scheduled payments on the debt security payable in equal installments (both principal and interest) over its term. The Bank evaluates its HTM securities for impairment quarterly on a collective, or pooled, basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. If management intends to sell an impaired security classified as HTM, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in other income (loss). See “ Note 4 — Investments ” for details on the allowance methodologies relating to AFS and HTM securities. Advances Advances (secured loans to members, former members, or eligible housing associates) are carried at amortized cost, which is net of premiums, discounts, and fair value hedging adjustments unless the Bank has elected the fair value option, in which case, the advances are carried at fair value. For advances carried at amortized cost, accrued interest receivable is recorded separately on the Statements of Condition. The Bank records interest on advances to interest income as earned. The Bank amortizes/accretes premiums, discounts, and fair value hedging adjustments on advances to income using the level-yield method over the contractual life of the advances. Advances carried at amortized cost are evaluated quarterly for expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. See “ Note 5 — Advances ” for details on the allowance methodology relating to advances. Past Due and Non-Accrual Advances. An advance is considered past due for financial reporting purposes if default of contractual principal or interest exists for a period of 30 days or more. Past due advances may consist of advances still accruing interest or advances on non-accrual status. An advance is placed on non-accrual status when full payment of principal and interest is not reasonably assured, regardless of delinquency status, or when principal or interest has been in default for a period of 90 days or more, unless the advance is both well-secured and in the process of collection. In general, the Bank would not expect advances to be placed on non-accrual status as they are required by regulation to be fully secured by underlying collateral. Prepayment Fees. The Bank charges a borrower a prepayment fee when the borrower prepays certain advances before the original maturity. For 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 Modifications. In cases in which the Bank funds a new advance to a borrower concurrently with or within a short period of time before or after the prepayment of an existing advance, the Bank evaluates whether the new advance meets the accounting criteria to qualify as a modification of an existing advance or whether it constitutes a new advance. The Bank compares the present value of cash flows on the new advance to the present value of cash flows remaining on the existing advance. If there is at least a ten percent difference in the present value of the cash flows or if the Bank concludes the difference between the advances is more than minor based on a qualitative assessment of the modifications made to the original contractual terms, then the advance is accounted for as a new advance and all prepayment fees or credits net of fair value hedging adjustments are recognized immediately to advance interest income on the Statements of Income. In all other instances, the advance is accounted for as a modification. When a new advance qualifies as a modification of an existing advance, any prepayment fee, net of the hedged item fair value hedging adjustments, as well as any outstanding premiums, discounts, or other adjustments on the prepaid advance, are deferred, recorded in the basis of the modified advance, and amortized over the contractual life of the modified advance using a level-yield methodology to advance interest income. Mortgage Loans Held for Portfolio The Bank classifies mortgage loans that it has the intent and ability to hold for the foreseeable future, or until maturity or payoff, as held for portfolio. Accordingly, these mortgage loans are reported net of premiums, discounts, basis adjustments from mortgage loan purchase commitments, charge-offs, and the allowance for credit losses. The Bank records interest on mortgage loans to interest income as earned. The Bank amortizes/accretes premiums, discounts, and basis adjustments on mortgage loan purchase commitments to income using the level-yield method over the contractual life of the mortgage loans. Accrued interest receivable is recorded separately on the Statements of Condition. The Bank performs a quarterly assessment of its mortgage loans held for portfolio to estimate expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The Bank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, the Bank measures the estimated loss over the remaining life of a mortgage loan, which also considers how the Bank’s credit enhancements mitigate credit losses. The Bank includes estimates of expected recoveries within the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as the Bank writes off accrued interest receivable by reversing interest income if a mortgage loan is placed on non-accrual status. The Bank does not purchase mortgage loans with credit deterioration at the time of purchase. See “ Note 6 — Mortgage Loans ” for details on the allowance methodology relating to mortgage loans. Past Due and Non-Accrual Loans. A mortgage loan is considered past due if the borrower has failed to make contractual principal and/or interest payments for a period of 30 days or more. The Bank places a conventional mortgage loan on non-accrual status if it is determined that either the collection of interest or principal is doubtful or interest or principal is 90 days or more past due. The Bank does not place a government-insured mortgage loan on non-accrual status due to the U.S. Government guarantee or insurance on the loan and contractual obligation of the loan servicer to repurchase the loan when certain criteria are met. For those mortgage loans placed on non-accrual status, accrued but uncollected interest is reversed against interest income and cash payments received are recorded as a reduction of principal. In addition, premiums, discounts, and basis adjustments from mortgage loan purchase commitments are not amortized while a loan is on non-accrual status. A loan on non-accrual status may be restored to accrual status when none of its contractual principal and interest is due and unpaid and the Bank expects repayment of the remaining contractual principal and interest. Modifications . Generally, the Bank only grants mortgage loan modifications to borrowers experiencing financial difficulty. If the terms of the modified loan are at least as favorable to the lender as the terms offered to borrowers with similar collection risks for comparable loans and the modification to the terms of the loan is more than minor, the loan meets the accounting criteria for a new loan. Generally, a modification would not result in a new loan because the modified terms are not as favorable to the lender as terms for comparable loans that would be offered to similar borrowers. The Bank does not consider changes to the terms of government-insured mortgage loans to be modifications due to the U.S. Government guarantee or insurance on the loan and contractual obligation of the loan servicer to repurchase the loan when certain criteria are met. The Bank places all modified loans on non-accrual status at the time of modification; however, these loans may be subsequently restored to accrual status if they meet the criteria noted in the non-accrual section above. Individually Evaluated Loans. The Bank individually evaluates all collateral-dependent loans for expected credit losses. Collateral-dependent loans are loans in which repayment is expected to be provided solely by the sale of the underlying collateral. The Bank’s collateral-dependent loans include loans in process of foreclosure, loans 180 days or more past due, bankruptcy loans 60 days or more past due, and modified loans on non-accrual status. The Bank measures these individually evaluated loans for expected credit loss based on the estimated fair value of the underlying property, less estimated selling costs and expected proceeds from PMI. All collateral-dependent loans are initially placed on non-accrual status; however, they may be subsequently restored to accrual status if they meet the criteria noted in the non-accrual section above. Charge-Off Policy . A charge-off is recorded if it is estimated that the amortized cost in a loan will not be recovered. The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include but are not limited to, the occurrence of foreclosure or when a loan is deemed collateral-dependent. The Bank charges-off the portion of the outstanding conventional mortgage loan balance in excess of the fair value of the underlying collateral, which is determined using property values, less estimated selling costs and expected proceeds from PMI. Derivatives All derivatives are recognized on the Statements of Condition at their fair values and reported as either derivative assets or derivative liabilities, net of cash collateral and accrued interest received from or pledged to clearing agents and/or counterparties. The fair values of derivatives are netted by clearing agent and/or counterparty when the netting requirements have been met. If these netted amounts result in a receivable to the Bank, they are classified as a derivative asset and, if classified as a payable to the clearing agent or counterparty, they are classified as a derivative liability. Cash flows associated with a derivative are reflected as cash flows from operating activities on the Statements of Cash Flows unless the derivative meets the criteria to be a financing derivative. 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 Dodd-Frank Act imposes two-way initial margin requirements, which are required to be satisfied with securities collateral. In addition, uncleared derivative agreements are generally fully collateralized with a zero unsecured threshold, which can be satisfied with cash or securities collateral, in accordance with variation margin requirements issued by the U.S. federal bank regulatory agencies and the CFTC. For cleared derivatives, the clearinghouse is the Bank’s counterparty. The Bank utilizes two clearinghouses, CME Clearing and 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 payments, and the clearing agent in turn notifies the Bank. Each clearinghouse determines initial margin requirements, which are considered collateral and can be satisfied with cash or securities. 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, which are a component of the derivative fair value, rather than cash collateral. Derivative Designations . Derivative instruments are designated by the Bank as: • a fair value hedge of an associated financial instrument or firm commitment (fair value hedge); or • an economic hedge to manage certain defined risks on the Bank’s Statements of Condition (economic hedge). These hedges are primarily used to: (i) manage mismatches between the coupon features of the Bank’s assets and liabilities, (ii) offset prepayment risk in certain assets, (iii) mitigate the income statement volatility that occurs when financial instruments are recorded at fair value and hedge accounting is not permitted by accounting guidance, or (iv) reduce exposure to interest reset risk. Accounting for Fair Value Hedges . If hedging relationships meet certain criteria, including, but not limited to, formal documentation of the fair value hedging relationship and an expectation to be highly effective, they qualify for fair value hedge accounting. At the inception of each fair value hedge transaction, the Bank formally documents the hedge relationship and its risk management objective and strategy for undertaking the hedge, including identification of the hedging instrument, the hedged item, the nature of the risk being hedged, and how the hedging instrument’s effectiveness in offsetting the exposure to changes in the hedged item’s fair value attributable to the hedged risk will be assessed. This process includes linking all derivatives that are designated as fair value hedges to assets and liabilities on the Statements of Condition and firm commitments. Changes in the fair value of a derivative that is designated and qualifies as a fair value hedge, along with changes in the fair value of the hedged asset or liability (or firm commitment) that are attributable to the hedged risk, are recorded in net interest income in the same line as the earnings effect of the hedged item. Two approaches to fair value hedge accounting include: • Long-haul hedge accounting . The application of long-haul hedge accounting requires the Bank to formally assess (both at the hedge’s inception and at least quarterly) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value of hedged items due to benchmark interest rate changes and whether those derivatives are expected to remain highly effective in future periods. The Bank uses regression analyses to assess the effectiveness of its long-haul hedges. • Short-cut hedge accounting . Transactions that meet certain criteria qualify for short-cut hedge accounting in which an assumption can be made that the change in fair value of a hedged item due to changes in the hedged risk, exactly offsets the change in fair value of the related derivative. Under the short-cut method, the entire change in fair value of the interest rate swap is considered to be highly effective at achieving offsetting changes in fair value of the hedged asset or liability. If documented at the time of hedge designation, a derivative relationship no longer qualifying for short-cut hedge accounting can fall back to the long-haul accounting method. Derivatives are typically executed at the same time as the hedged item, and the Bank designates the hedged item in a fair value hedging relationship at the trade date. In many hedging relationships, the Bank may designate the fair value hedging relationship upon its commitment to disburse an advance, or trade a consolidated obligation in which settlement occurs within the shortest period of time possible for the type of instrument based on market settlement conventions. The Bank then records the changes in fair value of the derivative and the hedged item beginning on the trade date. Accounting for Economic Hedges . An economic hedge is defined as a derivative hedging specific or non-specific underlying assets, liabilities, or firm commitments that does not qualify or was not designated for fair value hedge accounting, but is an acceptable hedging strategy under the Bank’s risk management program. Changes in the fair value of derivatives that are designated as economic hedges are recorded in other income (loss) as “Net gains (losses) on derivatives” with no offsetting fair value adjustments for the underlying assets, liabilities, or firm commitments, unless changes in the fair value of the those items are normally marked to fair value through earnings (e.g., trading securities and fair value option instruments). Accrued Interest Receivables and Payables . The net settlements of interest receivables and payables related to derivatives designated as fair value hedges are recognized as adjustments to the interest income or interest expense of the designated hedged item. The net settlements of interest receivables and payables related to derivatives designated as economic hedges are recognized in other income (loss) as “Net gains (losses) on derivatives.” Discontinuance of Hedge Accounting. The Bank discontinues fair value hedge accounting prospectively when either (i) it determines that the derivative is no longer highly effective in offsetting changes in the fair value of a hedged item due to changes in the benchmark interest rate, (ii) the derivative and/or the hedged item expires or is sold, terminated, or exercised, or (iii) management determines that designating the derivative as a hedging instrument is no longer appropriate. When fair value hedge accounting is discontinued, the Bank either terminates the derivative or continues to carry the derivative on the Statements of Condition at its fair value. For any remaining hedged item, the Bank ceases to adjust the hedged item for changes in fair value and amortizes the cumulative basis adjustment on the hedged item into earnings over the remaining contractual life of the hedged item using the level-yield method. Embedded Derivatives. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is embedded. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the debt, advance, or purchased financial instrument (the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. If the Bank determines that the embedded derivative has economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as an economic derivative instrument. However, if the Bank elects to carry the entire contract (the host contract and the embedded derivative) at fair value on the Statements of Condition, changes in fair value of the entire contract will be reported in current period earnings. Consolidated Obligations The Bank reports consolidated obligations at amortized cost, which is net of premiums, discounts, concessions, and fair value hedging adjustments unless the Bank has elected the fair value option, in which case the consolidated obligations are carried at fair value. The Bank records interest on consolidated obligations bonds to interest expense as incurred. The Bank amortizes/accretes premiums, discounts, concessions, and fair value hedging adjustments on consolidated obligations to expense using the level-yield method over the contractual life of the consolidated obligations. Concessions. The Bank pays concessions to dealers in connection with the issuance of certain consolidated obligations. The Office of Finance prorates the amount of the concession to each FHLBank, based upon the percentage of the debt issued that is attributed to that FHLBank. Concessions paid on consolidated obligations designated under the fair value option are expensed as incurred and recorded in other expense. Concessions paid on consolidated obligations not designated under the fair value option are deferred and amortized over the contractual life of the consolidated obligations using the level-yield method. Unamortized concessions are included as a direct deduction from the carrying amount of “Consolidated obligation discount notes” or “Consolidated obligation bonds” on the Statements of Condition and the amortization of those concessions is included in consolidated obligation interest expense. Off-Balance Sheet Credit Exposures The Bank evaluates its off-balance sheet credit exposures on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities, with a corresponding adjustment to the provision (reversal) for credit losses.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Adopted and Issued Accounting Guidance [Text Block]	Recently Adopted and Issued Accounting Guidance Segment Reporting (ASU 2023-07) On November 27, 2023, the FASB issued guidance improving reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This guidance became effective for the Bank for the annual period beginning on January 1, 2024, and for the interim periods beginning on January 1, 2025. The adoption of this guidance is not expected to have any effect on the Bank’s financial condition, results of operations, or cash flows; however, it may increase certain disclosures. Disclosure Improvements in Response to SEC Initiative (ASU 2023-06) On October 9, 2023, the FASB issued guidance amending various disclosure requirements in response to the SEC’s initiative to update and simplify disclosures. This guidance will become effective for the Bank on the date the SEC removes the related disclosure requirements from its existing regulations, to avoid duplication in FASB codification. The adoption of this guidance is not expected to have any effect on the Bank’s financial condition, results of operations, or cash flows; however, it may impact certain disclosures. Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) On March 31, 2022, the FASB issued guidance eliminating the accounting requirements for 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 from LIBOR. The guidance provided optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform, if certain criteria were met. These transactions included contract modifications, hedging relationships, and the sale/transfer of HTM debt securities. During the first half of 2023, the Bank elected the contractual modification and hedging relationship optional expedients and transitioned all of its outstanding LIBOR-indexed instruments to reference SOFR immediately after June 30, 2023, or at the beginning of the next reset period following LIBOR cessation. The election of the expedients did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. As of September 30, 2023, all of the Bank’s qualifying contracts had fully transitioned to SOFR.

Investments, Debt and Equity Securities [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure	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, 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 an NRSRO. At December 31, 2023 and 2022, none of these investments were with counterparties rated below triple-B; however, as of December 31, 2023 and 2022, approximately 35 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 December 31, 2023 and 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 $22 million and $11 million at December 31, 2023 and 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 December 31, 2023 and 2022. The carrying value of securities purchased under agreements to resell excludes accrued interest receivable of $5 million and $3 million at December 31, 2023 and 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.

The Bank had no sales of HTM securities during the years ended December 31, 2023, 2022, and 2021. Contractual Maturity The following table summarizes HTM securities by contractual maturity. Expected maturities of some securities may differ from contractual maturities, as borrowers may have the right to call or prepay obligations with or without call or prepayment fees (dollars in millions): December 31, 2023 December 31, 2022 Year of Contractual Maturity Amortized Fair Amortized Fair Non-mortgage-backed securities Due after one year through five years $ 249 $ 249 $ 254 $ 254 Due after five years through ten years 73 76 71 73 Due after ten years 73 78 77 81 Total non-mortgage-backed securities 395 403 402 408 Mortgage-backed securities 457 447 563 551 Total $ 852 $ 850 $ 965 $ 959 ALLOWANCE FOR CREDIT LOSSES ON AFS AND HTM SECURITIES The Bank evaluates AFS and HTM investment securities for credit losses on a quarterly basis. The Bank’s AFS and HTM securities may include, but are not limited to, certificates of deposit, commercial paper, U.S. obligations, GSE and TVA obligations, state or local housing agency obligations, taxable municipal bonds, and MBS. The Bank only purchases securities considered investment quality. At both December 31, 2023 and 2022, over 99 percent of the Bank’s AFS and HTM securities, based on amortized cost, were rated single-A or above by an NRSRO, based on the lowest long-term credit rating for each security. These NRSRO ratings may differ from any internal ratings of the securities by the Bank. The Bank evaluates its individual AFS securities for impairment by comparing the security’s fair value to its amortized cost. Impairment may exist when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). At December 31, 2023 and 2022, certain AFS securities held by the Bank were in an unrealized loss position. These losses are considered temporary as the Bank expects to recover the entire amortized cost basis on these AFS investment securities and neither intends to sell these securities nor considers it more likely than not that it will be required to sell these securities before its anticipated recovery of each security's remaining amortized cost basis. In addition, substantially all of these securities are high-quality GSE securities or carry an explicit government guarantee. In the case of GSE securities, they are purchased under an assumption that the issuers’ obligation to pay principal and interest on those securities will be honored, taking into account their status as GSEs. As a result, no allowance for credit losses was recorded on these AFS securities at December 31, 2023 and 2022. The Bank evaluates its HTM securities for impairment on a collective, or pooled, basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. At December 31, 2023 and 2022, the Bank had no allowance for credit losses recorded on its HTM securities because the securities: (i) were all highly-rated, (ii) had not experienced, nor did the Bank expect, any material payment default on the instruments, (iii) in the case of U.S. obligations, carry an explicit government guarantee, and (iv) in the case of GSE securities, they are purchased under an assumption that the issuers’ obligation to pay principal and interest on those securities will be honored, taking into account their status as GSEs.

Advances [Abstract]
Advances [Text Block]	Advances The Bank offers a wide range of fixed and variable rate advance products with different maturities, interest rates, payment characteristics, and optionality. Fixed rate advances generally have maturities ranging from overnight to 30 years. Variable rate advances generally have maturities ranging from one month to ten years, where the interest rates reset periodically to a specified interest rate index such as SOFR or consolidated obligation yields. REDEMPTION TERM The following table summarizes the Bank’s advances outstanding by redemption term (dollars in millions): December 31, 2023 December 31, 2022 Redemption Term Amount 1 Weighted Amount 1 Weighted Overdrawn demand deposit accounts $ 2 7.14 % $ 1 6.10 % Due in one year or less 52,890 5.34 61,578 4.26 Due after one year through two years 14,866 4.12 23,026 4.25 Due after two years through three years 13,230 3.95 10,790 3.47 Due after three years through four years 8,689 4.35 7,149 3.03 Due after four years through five years 30,189 5.55 6,047 3.89 Thereafter 3,355 3.51 3,783 3.03 Total par value 123,221 4.98 % 112,374 4.04 % Premiums 6 11 Fair value hedging adjustments (697) (1,183) Total $ 122,530 $ 111,202 1 Excludes accrued interest receivable of $392 million and $271 million at December 31, 2023 and 2022. The Bank offers advances to members and eligible housing associates that may be prepaid on predetermined dates (call dates) prior to maturity without incurring prepayment fees (callable advances). Other advances may require a prepayment fee or credit that makes the Bank financially indifferent to the prepayment of the advance. At December 31, 2023 and 2022 , the Bank had callable advances outstanding totaling $31.8 billion and $23.4 billion. The following table summarizes advances by year of redemption term or next call date for callable advances (dollars in millions): Redemption Term December 31, December 31, Overdrawn demand deposit accounts $ 2 $ 1 Due in one year or less 82,983 73,765 Due after one year through two years 12,136 20,883 Due after two years through three years 10,584 6,218 Due after three years through four years 5,980 4,468 Due after four years through five years 8,228 3,228 Thereafter 3,308 3,811 Total par value $ 123,221 $ 112,374 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 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 December 31, 2023 and 2022, the Bank had outstanding advances of $37.0 billion and $32.0 billion to Wells Fargo Bank, N.A., which represented 30 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 and manages its credit exposure to advances through an approach that includes establishing a credit limit for each borrower. This approach includes an ongoing review of each borrower’s financial condition in conjunction with the Bank’s collateral and lending policies to limit risk of loss while balancing borrowers’ needs for a reliable source of funding. In addition, the Bank lends to eligible borrowers in accordance with the FHLBank Act, Finance Agency regulations, and other applicable laws. The Bank is required by regulation to obtain sufficient collateral to fully secure its advances. The estimated value of the collateral required to secure each borrower’s advances is calculated by applying collateral discounts, or haircuts, to the unpaid principal balance or market value, as applicable, of the collateral. The Bank also has policies and procedures for validating the reasonableness of the Bank’s collateral valuations. In addition, collateral verifications and on-site reviews are performed by the Bank based on the risk profile of the borrower. Management believes that these policies effectively manage the Bank’s credit risk from advances. Eligible collateral includes: • fully disbursed whole first mortgages on improved residential real property or securities representing a whole interest in such mortgages; • loans and securities issued, insured, or guaranteed by the U.S. Government or any agency thereof, including MBS issued or guaranteed by Fannie Mae, Freddie Mac, and Ginnie Mae; • cash deposited with the Bank; and • other real estate-related collateral acceptable to the Bank, such as second lien mortgages, home equity lines of credit, municipal securities, and commercial real estate mortgages, provided such collateral has a readily ascertainable value and the Bank can perfect a security interest in it. CFIs may also pledge collateral consisting of secured small business, small agri-business, or small farm loans. As additional security, the FHLBank Act provides that the Bank has a lien on each member’s capital stock investment; however, capital stock cannot be pledged as collateral to secure advances. Collateral arrangements may vary depending upon borrower credit quality, financial condition and performance, borrowing capacity, and overall credit exposure to the borrower. The Bank can also require additional or substitute collateral to protect its security interest. The Bank periodically evaluates and makes changes to its collateral guidelines and collateral haircuts. Borrowers may pledge collateral to the Bank by executing a blanket pledge agreement, specifically assigning collateral, or placing physical possession of collateral with the Bank or its custodians. The Bank perfects its security interest in all pledged collateral by filing Uniform Commercial Code financing statements or by taking possession or control of the collateral. Under the FHLBank Act, any security interest granted to the Bank by its members, or any affiliates of its members, has priority over the claims and rights of any party (including any receiver, conservator, trustee, or similar party having rights of a lien creditor), unless those claims and rights would be entitled to priority under otherwise applicable law and are held by actual purchasers or by parties that have perfected security interests. Under a blanket pledge agreement, the Bank is granted a security interest in all financial assets of the borrower to fully secure the borrower’s obligation. Other than securities and cash deposits, the Bank does not initially take delivery of collateral from blanket pledge agreement borrowers. In the event of a default or a deterioration in the financial condition of a blanket pledge agreement borrower, the Bank has the ability to require delivery of pledged collateral sufficient to secure the borrower’s obligation. With respect to non-blanket pledge agreement borrowers that are federally insured, the Bank generally requires collateral to be specifically assigned. With respect to non-blanket pledge agreement borrowers that are not federally insured (typically insurance companies, CDFIs, and housing associates), the Bank generally takes control of collateral through the delivery of cash, securities, or loans to the Bank or its custodians. Using a risk-based approach and taking into consideration each borrower’s financial strength, the Bank considers the types and level of collateral to be the primary indicator of credit quality on its advances. At December 31, 2023 and 2022, the Bank had rights to collateral on a borrower-by-borrower basis with an unpaid principal balance or market value, as applicable, in excess of its outstanding advances. At December 31, 2023 and 2022, none of the Bank’s advances were past due, on non-accrual status, or considered impaired. The Bank considers its advances 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 years ended December 31, 2023 and 2022. The Bank has never experienced a credit loss on its advances. Based upon the Bank’s collateral and lending policies, the collateral held as security, and the repayment history on advances, management has determined that there were no expected credit losses on its advances at December 31, 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 MPF program. The Bank’s mortgage loan program involves investment by the Bank in single-family mortgage loans held for portfolio that are purchased from 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): December 31, 2023 2022 Fixed rate, long-term 1 single-family mortgage loans $ 8,939 $ 7,244 Fixed rate, medium-term 2 single-family mortgage loans 945 1,033 Total unpaid principal balance 9,884 8,277 Premiums 113 96 Discounts (11) (11) Basis adjustments from mortgage loan purchase commitments (13) (9) Total mortgage loans held for portfolio 3 9,973 8,353 Allowance for credit losses (6) (5) Total mortgage loans held for portfolio, net $ 9,967 $ 8,348 1 Long-term is defined as an original term of greater than 15 years and up to 30 years. 2 Medium-term is defined as an original term of 15 years or less. 3 Excludes accrued interest receivable of $58 million and $42 million at December 31, 2023 and 2022. The following table presents the Bank’s mortgage loans held for portfolio by collateral or guarantee type (dollars in millions): December 31, 2023 2022 Conventional mortgage loans $ 9,506 $ 7,890 Government-insured mortgage loans 378 387 Total unpaid principal balance $ 9,884 $ 8,277 PAYMENT STATUS OF MORTGAGE LOANS Payment status is the key credit quality indicator for conventional mortgage loans and allows the Bank to monitor borrower performance. Past due loans are those where the borrower has failed to make contractual principal and/or interest payments for a period of 30 days or more. Other delinquency statistics include non-accrual loans and loans in process of foreclosure. The following tables present the payment status for conventional mortgage loans (dollars in millions): December 31, 2023 Origination Year Prior to 2019 2019 to 2023 Total Past due 30 - 59 days $ 20 $ 30 $ 50 Past due 60 - 89 days 6 6 12 Past due 90 - 179 days 5 7 12 Past due 180 days or more 4 1 5 Total past due mortgage loans 35 44 79 Total current mortgage loans 1,752 7,758 9,510 Total amortized cost of mortgage loans 1 $ 1,787 $ 7,802 $ 9,589 December 31, 2022 Origination Year Prior to 2018 2018 to 2022 Total Past due 30 - 59 days $ 21 $ 22 $ 43 Past due 60 - 89 days 5 6 11 Past due 90 - 179 days 3 2 5 Past due 180 days or more 7 2 9 Total past due mortgage loans 36 32 68 Total current mortgage loans 1,764 6,128 7,892 Total amortized cost of mortgage loans 1 $ 1,800 $ 6,160 $ 7,960 1 Amortized cost represents the unpaid principal balance adjusted for unamortized premiums, discounts, price adjustment fees, basis adjustments, and direct write-downs. Amortized cost excludes accrued interest receivable. The following tables present other delinquency statistics for mortgage loans (dollars in millions): December 31, 2023 Amortized Cost Conventional Government-Insured Total In process of foreclosure 1 $ 2 $ 1 $ 3 Serious delinquency rate 2 — % 1 % — % Past due 90 days or more and still accruing interest 3 $ — $ 5 $ 5 Non-accrual mortgage loans 4 $ 40 $ — $ 40 December 31, 2022 Amortized Cost Conventional Government- Insured Total In process of foreclosure 1 $ 4 $ 1 $ 5 Serious delinquency rate 2 — % 2 % — % Past due 90 days or more and still accruing interest 3 $ — $ 8 $ 8 Non-accrual mortgage loans 4 $ 40 $ — $ 40 1 Includes loans where the decision of foreclosure or similar alternative such as pursuit of deed-in-lieu has been reported. 2 Represents mortgage loans that are 90 days or more past due or in the process of foreclosure expressed as a percentage of total mortgage loans. Serious delinquency rate on conventional loans was less than one percent at December 31, 2023 and 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 December 31, 2023 and 2022, $24 million and $29 million of conventional mortgage loans on non-accrual status were evaluated individually and do 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 is greater than the amortized cost of the loans. ALLOWANCE FOR CREDIT LOSSES The Bank evaluates mortgage loans for credit losses on a quarterly basis. Conventional Mortgage Loans Conventional mortgage loans are evaluated collectively when similar risk characteristics exists. Conventional loans that do not share risk characteristics with other pools are evaluated for expected credit losses on an individual basis. The Bank determines its allowances for credit losses on conventional loans through analyses that include consideration of various loan portfolio and collateral-related characteristics, such as past performance, current conditions, and reasonable and supportable forecasts of expected economic conditions. At December 31, 2023 and 2022, the Bank’s allowance for credit losses on conventional mortgage loans remained relatively stable at $6 million and $5 million. For collectively evaluated loans, the Bank uses a projected cash flow model to estimate expected credit losses over the life of the loans. This model relies on a number of inputs, such as current and projected property values and interest rates, as well as historical borrower behavior experience. The Bank also incorporates associated credit enhancements when determining its estimate of expected credit losses. The Bank may incorporate a management adjustment in the allowance for credit losses for conventional mortgage loans due to changes in economic and business conditions or other factors that may not be fully captured in its model. For individually evaluated loans, the Bank uses the practical expedient for collateral-dependent assets. A mortgage loan is considered collateral-dependent when repayment is expected to be provided solely by the sale of the underlying collateral. The Bank estimates the fair value of this collateral using a property valuation model. The expected credit loss of a collateral- dependent mortgage loan is equal to the difference between the amortized cost of the loan and the estimated fair value of the collateral, less estimated selling costs and expected proceeds from PMI. The Bank records a direct charge-off of the loan balance if certain triggering criteria are met. Expected recoveries of prior charge-offs are included in the allowance for credit losses. Government-Insured Mortgage Loans The Bank invests in government-insured fixed rate mortgage loans portfolios that are insured or guaranteed by the FHA, the Department of Veterans Affairs, Department of Housing and Urban Development, and/or the Rural Housing Service of the Department of Agriculture. The servicer or PFI obtains and maintains insurance or a guaranty from the applicable government agency. The servicer or PFI is responsible for compliance with all government agency requirements and for obtaining the benefit of the applicable guarantee or insurance with respect to defaulted government-insured mortgage loans. Any losses incurred on these loans that are not recovered from the insurer/guarantor are absorbed by the servicers. As such, the Bank only has credit risk for these loans if the servicer or PFI fails to pay for losses not covered by the guarantee or insurance, but in such instance, the Bank would have recourse against the servicer for such failure. The Bank has never experienced a credit loss on its government-insured mortgage loans. At December 31, 2023 and 2022, the Bank assessed its servicers and determined there was no expectation that a servicer would fail to remit payments due until paid in full. As a result, the Bank did not establish an allowance for credit losses for its government-insured mortgage loans at December 31, 2023 and 2022. Furthermore, none of these mortgage loans have been placed on non-accrual status because of the U.S. Government guarantee or insurance on these loans and the contractual obligation of the loan servicer to repurchase the loans when certain criteria are met.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities [Text Block]	Derivatives and Hedging Activities NATURE OF BUSINESS ACTIVITY The Bank is exposed to interest rate risk primarily from the effect of interest rate changes on its interest-earning assets and its related funding sources. The goal of the Bank’s interest rate risk management strategy is not to eliminate interest rate risk, but to manage it within appropriate limits. To mitigate the risk of loss, the Bank has established policies and procedures which include guidelines on the amount of exposure to interest rate changes it is willing to accept. 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 the speculative use of derivatives, and limit credit risk arising from derivatives. Derivative financial instruments are used by the Bank to achieve its financial and risk management objectives. The Bank reevaluates its hedging strategies periodically and may change the hedging techniques it uses or may adopt new strategies. The most common ways in which the Bank uses derivatives are to: • reduce the interest rate sensitivity and repricing gaps of assets and liabilities; • preserve an interest rate spread between the yield of an asset and the cost of the related liability. Without the use of derivatives, this interest rate spread could be reduced or eliminated when a change in the interest rate on the asset does not match a change in the interest rate on the liability; • mitigate the adverse earnings effects of the shortening or extension of certain assets and liabilities; • manage embedded options in assets and liabilities; and • reduce funding costs by combining a derivative with a consolidated obligation, as the cost of a combined funding structure can be lower than the cost of a comparable consolidated obligation. TYPES OF DERIVATIVES The Bank may use the following derivative instruments: • Interest Rate Swaps. An interest rate swap is an agreement between two entities to exchange cash flows in the future. The agreement sets the dates on which the cash flows will be exchanged and the manner in which the cash flows will be calculated. One of the simplest forms of an interest rate swap involves the promise by one party to pay cash flows equivalent to the interest on a notional amount at a predetermined fixed rate for a given period of time. In return for this promise, this party receives cash flows equivalent to the interest on the same notional amount at a variable interest rate index for the same period of time. The variable interest rate received or paid by the Bank in derivative transactions is primarily the OIS rate, based on either federal funds or SOFR. • Options. An option is an agreement between two entities that conveys the right, but not the obligation, to engage in a future transaction on some underlying security or other financial asset at an agreed-upon price during a certain period of time or on a specific date. Premiums or swap fees paid to acquire options are considered the fair value of the option at inception of the hedge and are reported as derivative assets on the Statements of Condition. • Swaptions. A swaption is an option on a swap that gives the buyer the right to enter into a specified interest rate swap at a certain time in the future. When used as a hedge, a swaption can protect the Bank against future interest rate changes. The Bank may enter into both payer and receiver swaptions. A payer swaption is the option to make fixed interest payments at a later date and a receiver swaption is the option to receive fixed interest payments at a later date. • Interest Rate Caps and Floors. In an interest rate cap agreement, a cash flow is generated if the price or interest rate of an underlying variable rises above a certain threshold (or “cap”) price. In an interest rate floor agreement, a cash flow is generated if the price or interest rate of an underlying variable falls below a certain threshold (or “floor”) price. Interest rate caps and floors are designed as protection against the interest rate on a variable rate asset or liability rising above or falling below a certain level. • Futures/Forwards Contracts. Futures and forwards contracts give the buyer the right to buy or sell a specific type of asset at a specific time at a given price. For example, certain mortgage loan purchase commitments entered into by the Bank are considered derivatives. The Bank may hedge these commitments by selling TBA MBS for forward settlement. A TBA MBS represents a forward contract for the sale of MBS at a future agreed-upon date for an established price. TYPES OF HEDGED ITEMS The Bank may have the following types of hedged items: • Investment Securities. The Bank primarily invests in U.S. Treasury obligations, other U.S. obligations, GSE and TVA obligations, state or local housing agency obligations, and agency MBS, and classifies them as either trading, AFS, or HTM. The interest rate and prepayment risk associated with these investment securities is managed through a combination of debt issuance and derivatives. To manage interest rate risk, the Bank may fund investment securities with callable consolidated obligations or utilize interest rate swaps, caps, floors, or swaptions. Derivatives held by the Bank that are associated with trading and HTM securities, if applicable, are economic hedges and derivatives held by the Bank associated with AFS securities are generally fair value hedges. • Advances. The Bank offers a wide range of fixed and variable rate advance products with different maturities, interest rates, payment characteristics, and optionality. The Bank may use derivatives to adjust the repricing and/or option characteristics of advances in order to more closely match the characteristics of its funding liabilities. In general, whenever a borrower executes a fixed rate advance or a variable rate advance with embedded options, the Bank may simultaneously execute a derivative with terms that offset the terms and embedded options, if any, in the advance. For example, the Bank may hedge a fixed rate advance with an interest rate swap where the Bank pays a fixed rate coupon and receives a variable rate coupon, effectively converting the fixed rate advance to a variable rate advance. This type of hedge is typically treated as a fair value hedge. In addition, the Bank may hedge a callable advance, which gives the borrower the option to extinguish the fixed rate advance, by entering into a cancelable interest rate swap. • Mortgage Loans. The Bank invests in fixed rate mortgage loans. The prepayment options embedded in mortgage loans can result in extensions or contractions in the expected repayment of these investments, depending on changes in actual and estimated prepayment speeds. The Bank manages the interest rate risk associated with mortgage loans through a combination of debt issuance and derivatives. The Bank may issue both callable and non-callable debt to achieve cash flow patterns and liability durations similar to those expected on the mortgage loans. The Bank may also purchase interest rate caps, floors, or swaptions to minimize the interest rate risk embedded in mortgage assets. Although these derivatives are valid economic hedges, they are not specifically linked to individual mortgage assets and, therefore, do not receive fair value hedge accounting. • Consolidated Obligations. The Bank may enter into derivatives to hedge the interest rate risk associated with its consolidated obligations. For example, the Bank may issue and hedge a fixed rate consolidated obligation with an interest rate swap where the Bank receives a fixed rate coupon and pays a variable rate coupon, effectively converting the fixed rate consolidated obligation to a variable rate consolidated obligation. This type of hedge is typically treated as a fair value hedge. The Bank may also issue variable interest rate consolidated obligations and simultaneously execute interest rate swaps to manage the interest rate risk of the variable interest rate debt. Interest rate swaps used to hedge variable interest rate debt do not qualify for hedge accounting and are treated as economic hedges. This strategy of issuing consolidated obligations while simultaneously entering into derivatives enables the Bank to offer a wider range of attractively priced advances to its borrowers and may allow the Bank to reduce its funding costs. • Firm Commitments . Certain mortgage loan purchase commitments are considered derivatives. The Bank normally hedges these commitments by selling TBA MBS for forward settlement. A TBA MBS represents a forward contract for the sale of MBS at a future agreed-upon date for an established price. The mortgage loan purchase commitment and the TBA used in the firm commitment hedging strategy are considered economic hedges. When the mortgage loan purchase commitment derivative settles, the current market value of the commitment is included with the basis of the mortgage loan and amortized over the contractual life of the mortgage loan using the level-yield method. The Bank may also hedge a firm commitment for a forward-starting advance through the use of an interest-rate swap, which is considered a fair value hedge. For additional information on the Bank’s derivatives, see “ Note 1 — Summary of Significant Accounting Policies .” 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): December 31, 2023 December 31, 2022 Notional Derivative Derivative Notional Derivative Derivative Derivatives designated as hedging instruments (fair value hedges) Interest rate swaps $ 112,954 $ 290 $ 98 $ 53,136 $ 226 $ 205 Derivatives not designated as hedging instruments (economic hedges) Interest rate swaps 53,050 1 2 48,347 11 13 Forward settlement agreements 115 — 1 46 — — Mortgage loan purchase commitments 112 1 — 46 — — Total derivatives not designated as hedging instruments 53,277 2 3 48,439 11 13 Total derivatives before netting and collateral adjustments $ 166,231 292 101 $ 101,575 237 218 Netting adjustments and cash collateral 1 975 (94) 406 (214) Total derivative assets and derivative liabilities $ 1,267 $ 7 $ 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.

The price alignment amount on variation margin for daily settled derivative contracts designated as hedging instruments is 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 analysis of derivative counterparties, collateral requirements, and adherence to the requirements set forth in the Bank’s policies, CFTC 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. Uncleared derivative transactions executed on or after September 1, 2022 are subject to two-way initial margin requirements as mandated by the 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 December 31, 2023, the Bank was not required to post initial margin on its uncleared derivative transactions in accordance with the noted regulation. For uncleared transactions, the derivative agreements are generally fully collateralized with a zero unsecured threshold in accordance with variation margin requirements issued by the U.S. federal bank regulatory agencies and the CFTC. For cleared derivatives, the clearinghouse is the Bank’s counterparty. The Bank utilizes two clearinghouses, CME Clearing and 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 December 31, 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 “ Note 1 — Summary of Significant Accounting Policies .” 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. The following tables present the fair value of derivative instruments meeting or not meeting the netting requirements and the related collateral received from or pledged to counterparties (dollars in millions): December 31, 2023 Derivative Instruments Meeting Netting Requirements Gross Amount Recognized 1 Gross Amounts of Netting Adjustments and Cash Collateral Derivative Instruments Not Meeting Netting Requirements 2 Total Derivative Assets and Total Derivative Liabilities Derivative Assets Uncleared derivatives $ 248 $ (245) $ 1 $ 4 Cleared derivatives 43 1,220 — 1,263 Total $ 291 $ 975 $ 1 $ 1,267 Derivative Liabilities Uncleared derivatives $ 95 $ (88) $ — $ 7 Cleared derivatives 6 (6) — — Total $ 101 $ (94) $ — $ 7 December 31, 2022 Derivative Instruments Meeting Netting Requirements Gross Amount Recognized 1 Gross Amounts of Netting Adjustments and Cash Collateral Derivative Instruments Not Meeting Netting Requirements 2 Total Derivative Assets and Total Derivative Liabilities Derivative Assets Uncleared derivatives $ 195 $ (194) $ — $ 1 Cleared derivatives 42 600 — 642 Total $ 237 $ 406 $ — $ 643 Derivative Liabilities Uncleared derivatives $ 200 $ (196) $ — $ 4 Cleared derivatives 18 (18) — — Total $ 218 $ (214) $ — $ 4 1 Represents derivative assets and derivative liabilities prior to netting adjustments and cash collateral, including accrued interest. 2 Represents mortgage loan purchase commitments not subject to enforceable netting requirements.

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 December 31, 2023 and 2022, the total par value of outstanding consolidated obligations of the FHLBanks was $1,204.3 billion and $1,181.7 billion.

Affordable Housing Program [Abstract]
Affordable Housing Program [Text Block]	Affordable Housing Program The FHLBank Act requires each FHLBank to establish and fund an AHP, which provides subsidies in the form of direct grants or below-market interest rates on advances to members who provide the funds to assist in the purchase, construction, or rehabilitation of housing for very low-, low-, or moderate-income households. Each FHLBank recognizes AHP assessment expense equal to the greater of 10 percent of its annual income subject to assessment, or its prorated sum required to ensure the aggregate contribution by the FHLBanks is no less than $100 million for each year. For purposes of the statutory AHP assessment, income subject to assessment is defined as net income before AHP assessments, plus interest expense related to MRCS. The exclusion of interest expense related to MRCS is a regulatory interpretation of the Finance Agency. The Bank accrues the AHP assessment monthly based on its income subject to assessment and reduces the AHP liability as program funds are distributed. If the Bank experienced a net loss for a full year, it would have no obligation to the AHP for the year, because its required annual AHP contribution is limited to its annual income subject to AHP assessment. If the aggregate 10 percent AHP calculation previously discussed was less than $100 million for the FHLBanks (i.e., a shortfall), each FHLBank would be required to contribute a prorated sum to ensure that the aggregate contribution by the FHLBanks equals $100 million. The pro-ration would be made on the basis of an FHLBank’s income in relation to the income of all FHLBanks for the year, subject to the annual income limitation previously discussed. In addition to the required AHP assessment, the Bank’s Board of Directors may elect to make voluntary contributions to the AHP. There was no contribution shortfall, as described above, in 2023, 2022, or 2021. If an FHLBank finds that its required contributions are contributing to its financial instability, it may apply to the Finance Agency for a temporary suspension of its contributions under the FHLBank Act. The Bank did not make any such application in 2023, 2022, or 2021. The following table presents a rollforward of the Bank’s AHP liability (dollars in millions): For the Years Ended December 31, 2023 2022 2021 Balance, beginning of year $ 135 $ 131 $ 162 Assessments 107 48 23 Voluntary contributions 5 — — Disbursements (49) (44) (54) Balance, end of year $ 198 $ 135 $ 131 .

Capital

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. Effective December 15, 2023, each member must purchase and hold membership capital stock in an amount equal to 0.06 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. In addition, each member is required to purchase activity-based capital stock equal to 4.50 percent of its outstanding advances, 4.00 percent of its outstanding mortgage loans, and 0.10 percent of its outstanding standby letters of credit. Prior to December 15, 2023, members were required to purchase and hold membership capital stock in an amount equal to 0.12 percent of their total assets as of the preceding December 31 st , subject to a cap of $10 million and a floor of $10,000. They were also required to purchase activity-based capital stock equal to 4.00 percent of their outstanding advances and mortgage loans and 0.10 percent of their outstanding 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 December 31, 2023 and 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, which represents 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 Bank recorded interest expense on MRCS of $1 million, $1 million, and $2 million for the years ended December 31, 2023, 2022, and 2021. As a result of the final rule on membership issued by the Finance Agency effective February 19, 2016, the eligibility requirements for FHLBank members were changed, rendering captive insurance companies ineligible for FHLBank membership. On the effective date of the final rule, the Bank reclassified the total outstanding capital stock held by all of the captive insurance companies that were Bank members to MRCS. On February 19, 2021, all remaining captive insurance company members that were admitted as members prior to September 12, 2014 had their membership terminated. The Bank immediately redeemed all membership stock from these captive insurance companies; however, the remaining activity-based stock is subject to the five year redemption period. The following table summarizes changes in MRCS (dollars in millions): For the Years Ended December 31, 2023 2022 2021 Balance, beginning of period $ 15 $ 29 $ 52 Capital stock reclassified to (from) MRCS, net 4 5 81 Net payments for repurchases/redemptions of MRCS (7) (19) (104) Balance, end of period $ 12 $ 15 $ 29 The following table summarizes the Bank’s MRCS by year of contractual redemption (dollars in millions): December 31, Year of Contractual Redemption 1 2023 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 6 7 Total $ 12 $ 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 JCE Agreement with all of the other FHLBanks in 2011. The JCE Agreement, as amended, is intended to enhance the capital position of the FHLBanks 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, 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 December 31, 2023 and 2022, the Bank’s restricted retained earnings account totaled $896 million and $703 million. ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) The following table summarizes changes in AOCI (dollars in millions): Net unrealized gains (losses) on AFS securities (Note 4) Pension and postretirement benefits Total AOCI Balance, December 31, 2020 $ 52 $ (4) $ 48 Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities 36 — 36 Net current period other comprehensive income (loss) 36 — 36 Balance, December 31, 2021 88 (4) 84 Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities (202) — (202) Net actuarial gains (losses) — 1 1 Net current period other comprehensive income (loss) (202) 1 (201) Balance, December 31, 2022 (114) (3) (117) Other comprehensive income (loss) before reclassifications Net unrealized gains (losses) on AFS securities (64) — (64) Net actuarial gains (losses) — 1 1 Net current period other comprehensive income (loss) (64) 1 (63) Balance, December 31, 2023 $ (178) $ (2) $ (180) 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 December 31, 2023 and 2022. In addition to the requirements previously discussed, 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): December 31, 2023 December 31, 2022 Required Actual Required Actual Regulatory capital requirements Risk-based capital $ 1,641 $ 10,023 $ 737 $ 8,883 Regulatory capital $ 7,376 $ 10,023 $ 6,567 $ 8,883 Leverage capital $ 9,220 $ 15,034 $ 8,208 $ 13,323 Capital-to-assets ratio 4.00 % 5.44 % 4.00 % 5.41 % Capital stock-to-assets ratio 2.00 % 3.59 % 2.00 % 3.73 % Leverage ratio 5.00 % 8.15 % 5.00 % 8.12 % CAPITAL CLASSIFICATION DETERMINATION The Finance Agency determines each FHLBank’s capital classification on at least a quarterly basis. If an FHLBank is determined to be other than adequately capitalized, that FHLBank becomes subject to additional supervisory authority by the Finance Agency. Before implementing a reclassification, the Director of the Finance Agency is required to provide the FHLBank with written notice of the proposed action and an opportunity to submit a response. As of the most recent notification date by the Finance Agency, the Bank was classified as adequately capitalized.

Pension and Other Postretirement Benefits Disclosure [Text Block]	Pension and Postretirement Benefit Plans QUALIFIED DEFINED BENEFIT MULTIEMPLOYER PLAN The Bank previously participated in the DB Plan, a tax-qualified defined benefit pension plan. In August of 2016, the Bank’s Board of Directors elected to freeze the DB Plan effective January 1, 2017. After the freeze, participants no longer accrued new benefits under the DB Plan. On May 2, 2023, the Bank completed a purchase agreement with Principal Life Insurance Company and transferred to them the future benefit obligations and annuity administration for participants under the DB Plan. As such, the Bank is no longer a party to the DB Plan. Refer to the 2022 Form 10-K for prior year details on the DB Plan. OTHER POSTRETIREMENT BENEFIT PLANS In addition to the DB Plan, the Bank has one qualified defined contribution benefit plan, the DC Plan. The Bank also offers the BEP, a nonqualified retirement plan which includes both a nonqualified defined contribution plan and a nonqualified defined benefit plan. In August of 2016, the Bank’s Board of Directors elected to freeze the BEP defined benefit plan effective January 1, 2017. After the freeze, participants no longer accrue new benefits under the BEP defined benefit plan.

Fair Value

Fair Value	12 Months Ended
	Dec. 31, 2023
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 Bank had no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy during the years ended December 31, 2023, 2022, or 2021. 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.

SUMMARY OF VALUATION TECHNIQUES AND PRIMARY INPUTS The valuation techniques and primary inputs used to develop the measurement of fair value for assets and liabilities that are measured at fair value on a recurring or non-recurring basis on the Statements of Condition are outlined below. Trading and AFS Investment Securities. The Bank’s valuation technique incorporates prices from multiple designated third-party pricing vendors, when available. The pricing vendors generally use various proprietary models to price investment securities. The inputs to those models are derived from various sources including, but not limited to, benchmark securities and yields, reported trades, dealer estimates, issuer spreads, bids, offers, and other market-related data. Since many investment securities do not trade on a daily basis, the pricing vendors use available information, as applicable, such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing to determine the prices for individual securities. Each pricing vendor has an established process in place to challenge investment valuations, which facilitates resolution of questionable prices identified by the Bank. Periodically, the Bank conducts reviews of its pricing vendors to confirm and further augment its understanding of the vendors’ pricing processes, methodologies, and control procedures for investment securities. The Bank’s valuation technique for estimating the fair values of its investment securities first requires the establishment of a median price for each security. All prices that are within a specified tolerance threshold of the median price are included in the cluster of prices that are averaged to compute a default price. All prices that are outside the threshold (outliers) are subject to further analysis (including, but not limited to, comparison to prices provided by an additional third-party valuation service, prices for similar securities, and/or non-binding dealer estimates) to determine if an outlier is a better estimate of fair value. If an outlier (or some other price identified in the analysis) is determined to be a better estimate of fair value, then the outlier (or the other price as appropriate) is used as the final price rather than the default price. Alternatively, if the analysis confirms that an outlier (or outliers) is (are) in fact not representative of fair value and the default price is the best estimate, then the default price is used as the final price. In all cases, the final price is used to determine the fair value of the security. In limited instances, when no prices are available from the designated pricing services, the Bank obtains prices from dealers or uses the purchase price if the investment security is unsettled. As of December 31, 2023 and 2022, multiple prices were received for the majority of the Bank’s trading and AFS investment securities. Based on the Bank’s review of the pricing methods and controls employed by the third-party pricing vendors and the relative lack of dispersion among the vendor prices, the Bank believes its final prices are representative of the prices that would have been received if the assets had been sold at the measurement date (i.e., exit prices) and further, that the fair value measurements are classified appropriately in the fair value hierarchy. Impaired Mortgage Loans Held for Portfolio. The fair value of impaired mortgage loans held for portfolio is estimated by obtaining property values from an external pricing vendor. This vendor utilizes multiple pricing models that generally factor in market observable inputs, including actual sales transactions and home price indices. The Bank applies an adjustment to these values to capture certain limitations in the estimation process and takes into consideration estimated selling costs and expected PMI proceeds. Derivative Assets and Liabilities and the Related Hedged Items. The fair value of derivatives is generally estimated using standard valuation techniques such as a discounted cash flow analysis and comparisons to similar instruments, and includes variation margin payments for daily settled contracts. In limited instances, fair value estimates for interest-rate related derivatives may be obtained using an external pricing model that utilizes observable market data. The Bank is subject to credit risk in derivatives transactions due to the potential nonperformance of its derivatives counterparties. The use of cleared derivatives is intended to mitigate credit risk exposure because a central counterparty is substituted for individual counterparties and collateral/payments is posted daily, through a clearing agent, for changes in the fair value of cleared derivatives. To mitigate credit risk on uncleared derivatives, the Bank enters into master netting agreements with its counterparties as well as collateral agreements that have collateral delivery thresholds. The Bank has evaluated the potential for the fair value of its derivatives to be affected by counterparty credit risk and its own credit risk and has determined that no adjustments were significant to the overall fair value measurements. The fair values of the Bank’s derivative assets and derivative liabilities include accrued interest receivable/payable and related cash collateral. The estimated fair values of the accrued interest receivable/payable and cash collateral approximate their carrying values due to their short-term nature. The fair values of derivatives are netted by clearing agent and/or counterparty if the netting requirements are met. If these netted amounts result in a receivable to the Bank, they are classified as an asset and, if classified as a payable to the clearing agent or counterparty, they are classified as a liability. The Bank’s discounted cash flow model utilizes market-observable inputs (inputs that are actively quoted and can be validated to external sources). The Bank uses the following inputs for measuring the fair value of interest-related derivatives: • Discount rate assumption . The Bank utilizes the federal funds OIS or SOFR OIS curve depending on the terms of the derivative agreement. • Forward interest rate assumption . The Bank utilizes the swap curve of the instrument’s index rate. • Volatility assumption . Market-based expectations of future interest rate volatility implied from current market prices for similar options. For forward settlement agreements, the Bank utilizes TBA security prices that are determined by coupon class and expected term until settlement. For mortgage loan purchase commitments, the Bank utilizes TBA security prices adjusted for factors such as credit risk and servicing spreads. For the related hedged items, the fair value is estimated using a discounted cash flow analysis which typically considers the following inputs: • Discount rate assumption . The Bank utilizes the designated benchmark interest rate curve. • Volatility assumption . Market-based expectations of future interest rate volatility implied from current market prices for similar options. Other Assets . These represent grantor trust assets, which are carried at estimated fair value based on quoted market prices as of the last business day of the reporting period. Consolidated Obligation Discount Notes Recorded under the Fair Value Option . The fair value of consolidated obligation discount notes recorded under the fair value option is determined by calculating the present value of the expected future cash flows. The discount rates used in the present value calculations are for consolidated obligations with similar terms. The Bank uses the consolidated obligation curve for measuring the fair value of these consolidated obligations, which is a market-observable curve constructed by the Office of Finance. This curve is constructed using the U.S. Treasury curve as a base curve which is then adjusted by adding indicative spreads obtained largely from market-observable sources. Subjectivity of Estimates . Estimates of the fair value of financial assets and liabilities using the methods previously described are highly subjective and require judgments regarding significant matters, such as the amount and timing of future cash flows, prepayment speed assumptions, expected interest rate volatility, possible distributions of future interest rates used to value options, and the selection of discount rates that appropriately reflect market and credit risks. The use of different assumptions could have a material effect on the fair value estimates.

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 December 31, 2023 and 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 years ended December 31, 2023 and 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 year ended December 31, 2023, net losses on financial instruments held under fair value option (i.e., discount notes) were $92 million compared to net gains of $106 million and $1 million in 2022 and 2021. 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 table summarizes 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): December 31, 2023 Unpaid Principal Balance Fair Value Fair Value Over (Under) Unpaid Principal Discount notes $ 48,164 $ 47,442 $ (722) 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 December 31, 2023 and 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 $1,032.1 billion and $1,027.1 billion. The following table summarizes additional off-balance sheet commitments for the Bank (dollars in millions): December 31, 2023 December 31, 2022 Expire Expire Total Total Standby letters of credit 1,2 $ 9,278 $ 118 $ 9,396 $ 6,566 Standby bond purchase agreements 2 83 769 852 736 Commitments to purchase mortgage loans 112 — 112 46 Commitments to issue bonds 47 — 47 3,200 Commitments to issue discount notes 551 — 551 202 Commitments to fund advances 2 2,123 40 2,163 128 1 Excludes commitments to issue standby letters of credit, when applicable. At both December 31, 2023 and 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 December 31, 2023 and 2022, based on its credit extension and collateral policies . 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 December 31, 2023 are currently no later than 2038. The carrying values of guarantees related to standby letters of credit are recorded in “Other liabilities” on the Statements of Condition and amounted to $4 million and $2 million at December 31, 2023 and 2022 . The Bank monitors the creditworthiness of its members and non-member housing associates that have standby letters of credit. 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 finance agencies 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 bonds until the designated marketing agent can find a suitable investor or the state housing finance agency 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 December 31, 2023, the Bank had standby bond purchase agreements with seven state housing finance agencies. The maturities of standby bond purchase agreements outstanding at December 31, 2023 are currently no later than 2028. During the years ended December 31, 2023, 2022, and 2021, 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 December 31, 2023 and 2022 is reported in “ N ote 7 — Derivatives and Hedging Activi ties ” 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 December 31, 2023, the Bank had commitments to issue $47 million and $551 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 December 31, 2023 and 2022, the Bank had commitments to fund advances of $2.2 billion 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 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 $178 million and $162 million at December 31, 2023 and 2022 . Legal Proceedings . The Bank is subject to various pending legal proceedings arising in the normal course of business. The Bank is not currently aware of any pending or threatened legal proceedings to which it is a party that it believes could have a material impact on its financial condition, results of operations, or cash flows.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Segment Reporting (ASU 2023-07) On November 27, 2023, the FASB issued guidance improving reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This guidance became effective for the Bank for the annual period beginning on January 1, 2024, and for the interim periods beginning on January 1, 2025. The adoption of this guidance is not expected to have any effect on the Bank’s financial condition, results of operations, or cash flows; however, it may increase certain disclosures. Disclosure Improvements in Response to SEC Initiative (ASU 2023-06) On October 9, 2023, the FASB issued guidance amending various disclosure requirements in response to the SEC’s initiative to update and simplify disclosures. This guidance will become effective for the Bank on the date the SEC removes the related disclosure requirements from its existing regulations, to avoid duplication in FASB codification. The adoption of this guidance is not expected to have any effect on the Bank’s financial condition, results of operations, or cash flows; however, it may impact certain disclosures. Troubled Debt Restructurings and Vintage Disclosures (ASU 2022-02) On March 31, 2022, the FASB issued guidance eliminating the accounting requirements for 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 from LIBOR. The guidance provided optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform, if certain criteria were met. These transactions included contract modifications, hedging relationships, and the sale/transfer of HTM debt securities. During the first half of 2023, the Bank elected the contractual modification and hedging relationship optional expedients and transitioned all of its outstanding LIBOR-indexed instruments to reference SOFR immediately after June 30, 2023, or at the beginning of the next reset period following LIBOR cessation. The election of the expedients did not have a material effect on the Bank’s financial condition, results of operations, or cash flows. As of September 30, 2023, all of the Bank’s qualifying contracts had fully transitioned to SOFR.
Basis of Accounting	BASIS OF PRESENTATION The Bank prepares its financial statements in accordance with GAAP.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make subjective assumptions and estimates that may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of income and expense. The most significant of these estimates include those used in conjunction with fair value estimates. Actual results could significantly differ from these estimates.
Investments	Debt Securities The Bank classifies investment securities as trading, AFS, or HTM at the date of acquisition. Purchases and sales of investment securities are recorded on a trade date basis. The Bank records interest on investment securities to interest income as earned. The Bank generally amortizes/accretes premiums and discounts on AFS and HTM investment securities to income using the contractual level-yield method (level-yield method). In addition, the Bank uses this method to amortize/accrete fair value hedging adjustments. The level-yield method recognizes the income effects of these adjustments over the contractual life of the securities based on the actual behavior of the underlying assets, including adjustments for actual prepayment activities, and reflects the contractual terms of the securities without regard to changes in estimated prepayments based on assumptions about future borrower behavior. For callable AFS and HTM non-MBS purchased at a premium, the Bank amortizes the premium to the next contractual call date. The Bank computes gains and losses on sales of investment securities using the specific identification method and includes these gains and losses in other income (loss). Trading . Securities classified as trading are carried at fair value and generally entered into for liquidity purposes. In addition, the Bank classifies certain securities as trading that do not qualify for hedge accounting, 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. The Bank records changes in the fair value of these securities through other income (loss) as “Net gains (losses) on trading securities.” The Bank does not participate in speculative trading practices and generally holds these investments until maturity, except to the extent management deems necessary to manage the Bank’s liquidity portfolio. Available-for-Sale. Securities that are not classified as trading or HTM are classified as AFS and carried at fair value. The Bank records changes in the fair value of these securities through AOCI as “Net unrealized gains (losses) on available-for-sale securities.” For AFS securities that have been hedged and qualify as a fair value hedge, the Bank records the portion of the change in the fair value of the security related to the risk being hedged in AFS interest income together with the related change in fair value of the derivative, and records the remainder of the change in fair value through AOCI as “Net unrealized gains (losses) on available-for-sale securities.” Held-to-Maturity . Securities that the Bank has both the ability and intent to hold to maturity are classified as HTM and carried at amortized cost, which represents the amount at which an investment is acquired, adjusted for periodic principal repayments, amortization of premiums, and accretion of discounts. Accrued interest receivable is recorded separately on the Statements of Condition. Certain changes in circumstances may cause the Bank to change its intent to hold a security to maturity without calling into question its intent to hold other debt securities to maturity in the future. Thus, the sale or transfer of a HTM security due to certain changes in circumstances, such as evidence of significant deterioration in the issuer’s creditworthiness or changes in regulatory requirements, is not considered to be inconsistent with its original classification. Other events that are isolated, non-recurring, and unusual for the Bank that could not have been reasonably anticipated may cause the Bank to sell or transfer an HTM security without necessarily calling into question its intent to hold other debt securities to maturity. In addition, the sale of a debt security that meets either of the following two conditions would not be considered inconsistent with the original classification of that security: (i) the sale occurs near enough to its maturity date (for example, within three months of maturity), or call date if exercise of the call is probable, that interest rate risk is substantially eliminated as a pricing factor and the changes in market interest rates would not have a significant effect on the security’s fair value or (ii) the sale occurs after the Bank has already collected a substantial portion (at least 85 percent) of the principal outstanding at acquisition due either to prepayments on the debt security or to scheduled payments on the debt security payable in equal installments (both principal and interest) over its term.
Advances	Advances Advances (secured loans to members, former members, or eligible housing associates) are carried at amortized cost, which is net of premiums, discounts, and fair value hedging adjustments unless the Bank has elected the fair value option, in which case, the advances are carried at fair value. For advances carried at amortized cost, accrued interest receivable is recorded separately on the Statements of Condition. The Bank records interest on advances to interest income as earned. The Bank amortizes/accretes premiums, discounts, and fair value hedging adjustments on advances to income using the level-yield method over the contractual life of the advances. Past Due and Non-Accrual Advances. An advance is considered past due for financial reporting purposes if default of contractual principal or interest exists for a period of 30 days or more. Past due advances may consist of advances still accruing interest or advances on non-accrual status. An advance is placed on non-accrual status when full payment of principal and interest is not reasonably assured, regardless of delinquency status, or when principal or interest has been in default for a period of 90 days or more, unless the advance is both well-secured and in the process of collection. In general, the Bank would not expect advances to be placed on non-accrual status as they are required by regulation to be fully secured by underlying collateral. Prepayment Fees. The Bank charges a borrower a prepayment fee when the borrower prepays certain advances before the original maturity. For 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 Modifications. In cases in which the Bank funds a new advance to a borrower concurrently with or within a short period of time before or after the prepayment of an existing advance, the Bank evaluates whether the new advance meets the accounting criteria to qualify as a modification of an existing advance or whether it constitutes a new advance. The Bank compares the present value of cash flows on the new advance to the present value of cash flows remaining on the existing advance. If there is at least a ten percent difference in the present value of the cash flows or if the Bank concludes the difference between the advances is more than minor based on a qualitative assessment of the modifications made to the original contractual terms, then the advance is accounted for as a new advance and all prepayment fees or credits net of fair value hedging adjustments are recognized immediately to advance interest income on the Statements of Income. In all other instances, the advance is accounted for as a modification. When a new advance qualifies as a modification of an existing advance, any prepayment fee, net of the hedged item fair value hedging adjustments, as well as any outstanding premiums, discounts, or other adjustments on the prepaid advance, are deferred, recorded in the basis of the modified advance, and amortized over the contractual life of the modified advance using a level-yield methodology to advance interest income.
Mortgage Loans	Mortgage Loans Held for Portfolio
Non-Accrual Loans	Past Due and Non-Accrual Loans. A mortgage loan is considered past due if the borrower has failed to make contractual principal and/or interest payments for a period of 30 days or more. The Bank places a conventional mortgage loan on non-accrual status if it is determined that either the collection of interest or principal is doubtful or interest or principal is 90 days or more past due. The Bank does not place a government-insured mortgage loan on non-accrual status due to the U.S. Government guarantee or insurance on the loan and contractual obligation of the loan servicer to repurchase the loan when certain criteria are met. For those mortgage loans placed on non-accrual status, accrued but uncollected interest is reversed against interest income and cash payments received are recorded as a reduction of principal. In addition, premiums, discounts, and basis adjustments from mortgage loan purchase commitments are not amortized while a loan is on non-accrual status. A loan on non-accrual status may be restored to accrual status when none of its contractual principal and interest is due and unpaid and the Bank expects repayment of the remaining contractual principal and interest.
Impairment of Financing Receivables	Individually Evaluated Loans. The Bank individually evaluates all collateral-dependent loans for expected credit losses. Collateral-dependent loans are loans in which repayment is expected to be provided solely by the sale of the underlying collateral. The Bank’s collateral-dependent loans include loans in process of foreclosure, loans 180 days or more past due, bankruptcy loans 60 days or more past due, and modified loans on non-accrual status. The Bank measures these individually evaluated loans for expected credit loss based on the estimated fair value of the underlying property, less estimated selling costs and expected proceeds from PMI. All collateral-dependent loans are initially placed on non-accrual status; however, they may be subsequently restored to accrual status if they meet the criteria noted in the non-accrual section above. Charge-Off Policy . A charge-off is recorded if it is estimated that the amortized cost in a loan will not be recovered. The Bank evaluates whether to record a charge-off on a conventional mortgage loan upon the occurrence of a confirming event. Confirming events include but are not limited to, the occurrence of foreclosure or when a loan is deemed collateral-dependent. The Bank charges-off the portion of the outstanding conventional mortgage loan balance in excess of the fair value of the underlying collateral, which is determined using property values, less estimated selling costs and expected proceeds from PMI.
Derivatives	Derivatives All derivatives are recognized on the Statements of Condition at their fair values and reported as either derivative assets or derivative liabilities, net of cash collateral and accrued interest received from or pledged to clearing agents and/or counterparties. The fair values of derivatives are netted by clearing agent and/or counterparty when the netting requirements have been met. If these netted amounts result in a receivable to the Bank, they are classified as a derivative asset and, if classified as a payable to the clearing agent or counterparty, they are classified as a derivative liability. Cash flows associated with a derivative are reflected as cash flows from operating activities on the Statements of Cash Flows unless the derivative meets the criteria to be a financing derivative. 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 Dodd-Frank Act imposes two-way initial margin requirements, which are required to be satisfied with securities collateral. In addition, uncleared derivative agreements are generally fully collateralized with a zero unsecured threshold, which can be satisfied with cash or securities collateral, in accordance with variation margin requirements issued by the U.S. federal bank regulatory agencies and the CFTC. For cleared derivatives, the clearinghouse is the Bank’s counterparty. The Bank utilizes two clearinghouses, CME Clearing and 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 payments, and the clearing agent in turn notifies the Bank. Each clearinghouse determines initial margin requirements, which are considered collateral and can be satisfied with cash or securities. 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, which are a component of the derivative fair value, rather than cash collateral. Derivative Designations . Derivative instruments are designated by the Bank as: • a fair value hedge of an associated financial instrument or firm commitment (fair value hedge); or • an economic hedge to manage certain defined risks on the Bank’s Statements of Condition (economic hedge). These hedges are primarily used to: (i) manage mismatches between the coupon features of the Bank’s assets and liabilities, (ii) offset prepayment risk in certain assets, (iii) mitigate the income statement volatility that occurs when financial instruments are recorded at fair value and hedge accounting is not permitted by accounting guidance, or (iv) reduce exposure to interest reset risk. Accounting for Fair Value Hedges . If hedging relationships meet certain criteria, including, but not limited to, formal documentation of the fair value hedging relationship and an expectation to be highly effective, they qualify for fair value hedge accounting. At the inception of each fair value hedge transaction, the Bank formally documents the hedge relationship and its risk management objective and strategy for undertaking the hedge, including identification of the hedging instrument, the hedged item, the nature of the risk being hedged, and how the hedging instrument’s effectiveness in offsetting the exposure to changes in the hedged item’s fair value attributable to the hedged risk will be assessed. This process includes linking all derivatives that are designated as fair value hedges to assets and liabilities on the Statements of Condition and firm commitments. Changes in the fair value of a derivative that is designated and qualifies as a fair value hedge, along with changes in the fair value of the hedged asset or liability (or firm commitment) that are attributable to the hedged risk, are recorded in net interest income in the same line as the earnings effect of the hedged item. Two approaches to fair value hedge accounting include: • Long-haul hedge accounting . The application of long-haul hedge accounting requires the Bank to formally assess (both at the hedge’s inception and at least quarterly) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value of hedged items due to benchmark interest rate changes and whether those derivatives are expected to remain highly effective in future periods. The Bank uses regression analyses to assess the effectiveness of its long-haul hedges. • Short-cut hedge accounting . Transactions that meet certain criteria qualify for short-cut hedge accounting in which an assumption can be made that the change in fair value of a hedged item due to changes in the hedged risk, exactly offsets the change in fair value of the related derivative. Under the short-cut method, the entire change in fair value of the interest rate swap is considered to be highly effective at achieving offsetting changes in fair value of the hedged asset or liability. If documented at the time of hedge designation, a derivative relationship no longer qualifying for short-cut hedge accounting can fall back to the long-haul accounting method. Derivatives are typically executed at the same time as the hedged item, and the Bank designates the hedged item in a fair value hedging relationship at the trade date. In many hedging relationships, the Bank may designate the fair value hedging relationship upon its commitment to disburse an advance, or trade a consolidated obligation in which settlement occurs within the shortest period of time possible for the type of instrument based on market settlement conventions. The Bank then records the changes in fair value of the derivative and the hedged item beginning on the trade date. Accounting for Economic Hedges . An economic hedge is defined as a derivative hedging specific or non-specific underlying assets, liabilities, or firm commitments that does not qualify or was not designated for fair value hedge accounting, but is an acceptable hedging strategy under the Bank’s risk management program. Changes in the fair value of derivatives that are designated as economic hedges are recorded in other income (loss) as “Net gains (losses) on derivatives” with no offsetting fair value adjustments for the underlying assets, liabilities, or firm commitments, unless changes in the fair value of the those items are normally marked to fair value through earnings (e.g., trading securities and fair value option instruments). Accrued Interest Receivables and Payables . The net settlements of interest receivables and payables related to derivatives designated as fair value hedges are recognized as adjustments to the interest income or interest expense of the designated hedged item. The net settlements of interest receivables and payables related to derivatives designated as economic hedges are recognized in other income (loss) as “Net gains (losses) on derivatives.” Discontinuance of Hedge Accounting. The Bank discontinues fair value hedge accounting prospectively when either (i) it determines that the derivative is no longer highly effective in offsetting changes in the fair value of a hedged item due to changes in the benchmark interest rate, (ii) the derivative and/or the hedged item expires or is sold, terminated, or exercised, or (iii) management determines that designating the derivative as a hedging instrument is no longer appropriate. When fair value hedge accounting is discontinued, the Bank either terminates the derivative or continues to carry the derivative on the Statements of Condition at its fair value. For any remaining hedged item, the Bank ceases to adjust the hedged item for changes in fair value and amortizes the cumulative basis adjustment on the hedged item into earnings over the remaining contractual life of the hedged item using the level-yield method.
Derivative Offsetting	Financial Instruments Meeting Netting Requirements The Bank has certain financial instruments, including derivative instruments and securities purchased under agreements to resell, that may be presented on a net basis when there is a legal right of offset and all other requirements for netting are met (collectively referred to as the netting requirements). The Bank has elected to offset its derivative instruments, related cash collateral, and associated accrued interest when it has met the netting requirements. The net exposure for these financial instruments can change on a daily basis and, therefore, there may be a delay between the time this exposure change is identified and additional collateral is requested, and the time when this collateral is received or pledged. Likewise, there may be a delay for excess collateral to be returned. For derivative instruments that meet the requirements for netting, any excess cash collateral received or pledged is recognized as a derivative liability or derivative asset. Additional information regarding these agreements is provided in “ Note 7 — Derivatives and Hedging Activities. ”
Embedded Derivatives	Embedded Derivatives. The Bank may issue debt, make advances, or purchase financial instruments in which a derivative instrument is embedded. Upon execution of these transactions, the Bank assesses whether the economic characteristics of the embedded derivative are clearly and closely related to the economic characteristics of the remaining component of the debt, advance, or purchased financial instrument (the host contract) and whether a separate, non-embedded instrument with the same terms as the embedded instrument would meet the definition of a derivative instrument. If the Bank determines that the embedded derivative has economic characteristics that are not clearly and closely related to the economic characteristics of the host contract and a separate, stand-alone instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from the host contract, carried at fair value, and designated as an economic derivative instrument. However, if the Bank elects to carry the entire contract (the host contract and the embedded derivative) at fair value on the Statements of Condition, changes in fair value of the entire contract will be reported in current period earnings.
Consolidated Obligations	Consolidated Obligations The Bank reports consolidated obligations at amortized cost, which is net of premiums, discounts, concessions, and fair value hedging adjustments unless the Bank has elected the fair value option, in which case the consolidated obligations are carried at fair value. The Bank records interest on consolidated obligations bonds to interest expense as incurred. The Bank amortizes/accretes premiums, discounts, concessions, and fair value hedging adjustments on consolidated obligations to expense using the level-yield method over the contractual life of the consolidated obligations. Concessions. The Bank pays concessions to dealers in connection with the issuance of certain consolidated obligations. The Office of Finance prorates the amount of the concession to each FHLBank, based upon the percentage of the debt issued that is attributed to that FHLBank. Concessions paid on consolidated obligations designated under the fair value option are expensed as incurred and recorded in other expense. Concessions paid on consolidated obligations not designated under the fair value option are deferred and amortized over the contractual life of the consolidated obligations using the level-yield method. Unamortized concessions are included as a direct deduction from the carrying amount of “Consolidated obligation discount notes” or “Consolidated obligation bonds” on the Statements of Condition and the amortization of those concessions is included in consolidated obligation interest expense.
Mandatorily Redeemable Capital Stock	Mandatorily Redeemable Capital Stock The Bank reclassifies capital stock subject to redemption from equity to MRCS at the time shares meet the definition of a mandatorily redeemable financial instrument. This occurs after a member provides written notice of redemption, gives 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. Shares meeting this definition are reclassified to a liability at fair value. Dividends on MRCS are classified as interest expense on the Statements of Income. The repurchase or redemption of MRCS is transacted at par value and is reflected as a cash outflow in the financing activities section of the Statements of Cash Flows. If a member cancels its written notice of redemption or notice of withdrawal, the Bank will reclassify MRCS from a liability to equity. After the reclassification, dividends on the capital stock will no longer be classified as interest expense.

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.
Fair Value Transfers	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.
Allowance for Credit Losses	The Bank invests in interest-bearing deposits, securities purchased under agreements to resell, and federal funds sold. Interest-bearing deposits include deposits held with banks or counterparties that do not meet the definition of a security. The Bank treats securities purchased under agreements to resell as short-term collateralized loans. Federal funds sold consist of short-term, unsecured loans generally transacted by counterparties that are considered investment quality by the Bank. All of these investments provide short-term liquidity and are carried at amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. These investments are evaluated quarterly for expected credit losses. If applicable, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The Bank uses the collateral maintenance provision practical expedient for securities purchased under agreements to resell. Consequently, a credit loss would be recognized if there is a collateral shortfall which the Bank does not believe the counterparty will replenish in accordance with its contractual terms. The credit loss would be limited to the difference between the fair value of the collateral and the investment’s amortized cost. See “ Note 4 — Investments ” for details on the allowance methodologies relating to these investments. The Bank evaluates its individual AFS securities for impairment quarterly by comparing the security’s fair value to its amortized cost. Accrued interest receivable is recorded separately on the Statements of Condition. Impairment may exist when the fair value of the investment is less than its amortized cost (i.e., in an unrealized loss position). In assessing whether a credit loss exists on an impaired security, the Bank considers whether there would be a shortfall in receiving all cash flows contractually due. When a shortfall is considered possible, the Bank compares the present value of cash flows to be collected from the security with the amortized cost basis of the security. If the present value of cash flows is less than amortized cost, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance is limited by the amount of the unrealized loss. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. If management intends to sell an impaired security classified as AFS, or more likely than not will be required to sell the security before expected recovery of its amortized cost basis, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in other income (loss). If management does not intend to sell an impaired security classified as AFS and it is not more likely than not that management will be required to sell the debt security, then the credit portion of the difference is recognized as an allowance for credit losses and any remaining difference between the security’s fair value and amortized cost is recorded to “Net unrealized gains (losses) on available-for-sale securities” within AOCI. The Bank evaluates its HTM securities for impairment quarterly on a collective, or pooled, basis unless an individual assessment is deemed necessary because the securities do not possess similar risk characteristics. An allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. If management intends to sell an impaired security classified as HTM, any allowance for credit losses is written off and the amortized cost basis is written down to the security’s fair value at the reporting date with any incremental impairment reported in other income (loss). Advances carried at amortized cost are evaluated quarterly for expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The allowance for credit losses excludes uncollectible accrued interest receivable, which is measured separately, if applicable. See “ Note 5 — Advances ” for details on the allowance methodology relating to advances. The Bank performs a quarterly assessment of its mortgage loans held for portfolio to estimate expected credit losses. If deemed necessary, an allowance for credit losses is recorded with a corresponding adjustment to the provision (reversal) for credit losses. The Bank measures expected credit losses on mortgage loans on a collective basis, pooling loans with similar risk characteristics. If a mortgage loan no longer shares risk characteristics with other loans, it is removed from the pool and evaluated for expected credit losses on an individual basis. When developing the allowance for credit losses, the Bank measures the estimated loss over the remaining life of a mortgage loan, which also considers how the Bank’s credit enhancements mitigate credit losses. The Bank includes estimates of expected recoveries within the allowance for credit losses. The allowance excludes uncollectible accrued interest receivable, as the Bank writes off accrued interest receivable by reversing interest income if a mortgage loan is placed on non-accrual status. The Bank does not purchase mortgage loans with credit deterioration at the time of purchase. See “ Note 6 — Mortgage Loans ” for details on the allowance methodology relating to mortgage loans. The Bank evaluates its off-balance sheet credit exposures on a quarterly basis for expected credit losses. If deemed necessary, an allowance for expected credit losses on these off-balance sheet exposures is recorded in other liabilities, with a corresponding adjustment to the provision (reversal) for credit losses. See “ Note 14 — Commitments and Contingencies ” for additional information.
Loans And Leases Receivable Modification Policy	Modifications . Generally, the Bank only grants mortgage loan modifications to borrowers experiencing financial difficulty. If the terms of the modified loan are at least as favorable to the lender as the terms offered to borrowers with similar collection risks for comparable loans and the modification to the terms of the loan is more than minor, the loan meets the accounting criteria for a new loan. Generally, a modification would not result in a new loan because the modified terms are not as favorable to the lender as terms for comparable loans that would be offered to similar borrowers. The Bank does not consider changes to the terms of government-insured mortgage loans to be modifications due to the U.S. Government guarantee or insurance on the loan and contractual obligation of the loan servicer to repurchase the loan when certain criteria are met. The Bank places all modified loans on non-accrual status at the time of modification; however, these loans may be subsequently restored to accrual status if they meet the criteria noted in the non-accrual section above.

Fair Value Summary	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.
