The process by which banks borrow from the Federal Reserve is called the discount window, and the interest rate that the federal Reserve charges is called the discount rate. When the discount rate is increased, it is more expensive for banks to borrow in order to cover their reserve requirements.
These loans take place in a private financial market called the federal funds market. The interest rate on the overnight borrowing of reserves is called the federal funds rate or simply the âfunds rate.â It adjusts to balance the supply of and demand for reserves. For example, if the supply of reserves in the fed funds market is greater than the demand, then the funds rate falls, and if the supply of reserves is less than the demand, the funds rate rises.
