U.S. bank bond portfolios ended 2025 about $300 billion below book value.
The Federal Reserve's May 2026 Financial Stability Report says the combined fair values of available-for-sale and held-to-maturity securities were $300 billion below their book values.
The mechanism is interest-rate risk: when yields rise, older low-coupon bonds lose market value. AFS and HTM holdings then follow different accounting paths. AFS fair-value changes enter other comprehensive income; HTM securities can remain at amortized cost if held.
The economic gap matters most when liquidity forces a sale. Stable funding can give a bank time to hold the bond to maturity.
Critical caveat: $300B is a fair-value shortfall—not $300B of realized losses, not $300B of credit defaults and not a forecast of bank failures. The Fed also said the gap had fallen from its 2022 peak as banks reduced duration.
