Get policy rates

Prior to 2021-07-08 it is the rate on excess reserves (IOER rate) After 2021-07-08 it is the rate on reserve balances (IORB rate)

The IOER rate was the primary tool used by the Federal Reserve to set a floor on the federal funds rate. While the Interest rate on required reserves (IORR rate) existed, the IOER rate had a more direct impact on market rates, as banks typically held far more excess reserves than required reserves. Therefore, the IOER rate was more influential in the Fed’s monetary policy implementation.
