The Fed's banking lifeline expires

On 11 March, the Federal Reserve officially ceased issuing new loans under the Bank Term Funding Program (BTFP), terminating the emergency lending facility launched during the regional banking panic of 2023. The facility fulfilled its purpose by allowing lenders to pledge underwater securities at par, but its expiration removes a critical balance-sheet safety net.

The Loss of Par Collateral

With the BTFP closed, commercial banks holding underwater Treasury and agency mortgage securities can no longer access par liquidity; they must rely on the discount window, where collateral is subject to market haircuts. While wholesale funding conditions have normalized, regional banks with large unrealized securities losses remain vulnerable to sudden liquidity shocks. The training wheels of central bank balance-sheet protection have been removed.

The expiration of the Fed’s BTFP facility strips regional lenders of emergency par liquidity, forcing banks to confront their underwater securities portfolios on standard market terms.
