| 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. 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 following table summarizes the carrying value, fair value, and fair value hierarchy of the Bank’s financial instruments (dollars in millions). | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | June 30, 2026 | | | | | Fair Value | | Financial Instruments | | Carrying Value | | Level 1 | | Level 2 | | Level 3 | | Netting Adjustments and Cash Collateral1 | | Total | | Assets | | | | | | | | | | | | | | Cash and due from banks | | $ | 58 | | | $ | 58 | | | $ | — | | | $ | — | | | $ | — | | | $ | 58 | | | Interest-bearing deposits | | 5,213 | | | — | | | 5,213 | | | — | | | — | | | 5,213 | | | Securities purchased under agreements to resell | | 19,300 | | | — | | | 19,300 | | | — | | | — | | | 19,300 | | | Federal funds sold | | 12,050 | | | — | | | 12,050 | | | — | | | — | | | 12,050 | | | Trading securities | | 6,067 | | | — | | | 6,067 | | | — | | | — | | | 6,067 | | | Available-for-sale securities | | 28,775 | | | — | | | 28,775 | | | — | | | — | | | 28,775 | | | Held-to-maturity securities | | 413 | | | — | | | 413 | | | 2 | | | — | | | 415 | | | Advances | | 124,489 | | | — | | | 124,606 | | | — | | | — | | | 124,606 | | | Mortgage loans held for portfolio, net | | 15,518 | | | — | | | 14,864 | | | 45 | | | — | | | 14,909 | | | | | | | | | | | | | | | | Accrued interest receivable | | 508 | | | — | | | 508 | | | — | | | — | | | 508 | | | Derivative assets, net | | 88 | | | — | | | 269 | | | — | | | (181) | | | 88 | | | Other assets | | 54 | | | 54 | | | — | | | — | | | — | | | 54 | | | Liabilities | | | | | | | | | | | | | | Deposits | | (1,339) | | | — | | | (1,339) | | | — | | | — | | | (1,339) | | | Consolidated obligations | | | | | | | | | | | | | Discount notes2 | | (97,342) | | | — | | | (97,318) | | | — | | | — | | | (97,318) | | | Bonds | | (100,762) | | | — | | | (100,142) | | | — | | | — | | | (100,142) | | | Total consolidated obligations | | (198,104) | | | — | | | (197,460) | | | — | | | — | | | (197,460) | | | | | | | | | | | | | | | | MRCS | | (59) | | | (59) | | | — | | | — | | | — | | | (59) | | | Accrued interest payable | | (677) | | | — | | | (677) | | | — | | | — | | | (677) | | | Derivative liabilities, net | | (7) | | | — | | | (52) | | | — | | | 45 | | | (7) | | | | | | | | | | | | | | |

The fair value information presented is as of the date the fair value adjustment was recorded during the year ended December 31, 2025. 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, and unrecognized firm commitments. 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 the three and six months ended June 30, 2026, the Bank recorded net gains on financial instruments held under fair value option (i.e., discount notes) of less than $1 million and $6 million compared to $7 million and $27 million for the same periods in 2025. The following tables summarize the difference between the unpaid principal balance and fair value of outstanding instruments for which the fair value option has been elected (dollars in millions):
