In particular, short-term rates have been surprisingly firm in recent months, despite the large increase in reserves by the Fed as a part of its response to the coronavirus pandemic. In this post, we provide evidence that both the supply of reserves and the supply of short-term Treasury securities are important factors for explaining short-term rates.

Federal Reserve tools for managing rates and reserves

Raising the Fed’s overnight reverse repo rate up to IOER would increase liquidity, expediently reduce the overabundance of reserves, and stabilize the volatility of overnight market rates.
