Federal funds can be defined as the unsecured loan transactions of reserved balances at Federal Reserve Banks that depository institutions make to one another. And the rate at which these transactions occur is called the federal funds rate or fed fund rate.

The federal funds market committee (FOMC) has an important role in the execution of market policy as it sets the target level for the federal funds that influences the supply of reserves in the banking system. Federal fund open market actions or operations bring changes in the supply of reserve balances in the system thus creating a variable pressure on the federal funds rate.
