Effective July 29, 2021, the Board of Governors of the Federal Reserve System will replace the interest rate on excess reserves (IOER) and the interest rate on required reserves (IORR) with a single rate, the interest rate on reserve balances (IORB). Therefore, FRED has discontinued the IOER and the IORR rates and added the IORB rate. See the Board’s announcement for more details.
The IORB rate is the rate of interest that the Federal Reserve pays on balances maintained by or on behalf of eligible institutions in master accounts at Federal Reserve Banks. The interest rate is set by the Board of Governors, and it is an important tool of monetary policy. See Policy Tools and IORB FAQs for more information.
