The FIMA Repo Facility is a standing repurchase agreement facility operated by the Federal Reserve for foreign and international monetary authorities. It allows foreign central banks to temporarily exchange their U.S. Treasury holdings for dollars, providing a backstop source of dollar liquidity.
Example
“During a global dollar shortage, the Bank of Japan utilized the FIMA Repo Facility to obtain USD liquidity by temporarily swapping its U.S. Treasury holdings, stabilizing its domestic dollar funding market.”
