FIMA Repo Facility (2020)
mechanismMoney & Finance
The Fed built a side door so foreign governments never have to sell America's debt — they pawn it instead.
Who they are
The FIMA Repo Facility, created by the Federal Reserve on March 31, 2020.
What they do
Foreign central banks can swap their US Treasuries for overnight dollars — up to $60 billion — instead of selling them on the open market.
How it works
Selling would push US borrowing costs up. Pawning doesn't. In August 2026, after the yen rescue, Treasury Secretary Bessent publicly pushed the Fed to raise the cap so Japan could keep defending its currency without touching its Treasury pile.
Why it matters
It's a shield for the system's core collateral: whatever happens to anyone's currency, America's debt must not be dumped.
The engine's record — word for word
Federal Reserve facility established March 31, 2020: approved foreign central banks swap their US Treasuries for overnight dollars (standard cap $60B) instead of selling outright — a pressure valve that prevents foreign UST dumping from spiking US yields (BIS/Fed working papers). Protects the core collateral of the system. Aug 2026: after the Jul 31 yen intervention, Treasury Secretary Bessent publicly pushed the Warsh Fed to raise the cap so Japan can defend the yen without selling Treasuries — FOMC approval required (CNBC, Bloomberg, US News).
