FFR meaning in Governmental ?

In the United States, the federal funds rate is the interest rate at which depository institutions (banks and credit unions) lend reserve balances to other depository institutions overnight on an uncollateralized basis. Reserve balances are amounts held at the Federal Reserve to maintain depository institutions' reserve requirements. Institutions with surplus balances in their accounts lend those balances to institutions in need of larger balances. The federal funds rate is an important benchmark in financial markets.

The Effective Federal Funds Rate (EFFR) is calculated as the effective median interest rate of overnight federal funds transactions during the previous business day. It is published daily by the Federal Reserve Bank of New York.

The federal funds target rate is determined by a meeting of the members of the Federal Open Market Committee which normally occurs eight times a year about seven weeks apart. The committee may also hold additional meetings and implement target rate changes outside of its normal schedule.

The Federal Reserve uses open market operations to make the federal funds effective rate follow the federal funds target rate. The target rate is chosen in part to influence the money supply in the U.S. economy.
