The fed funds rate is the interest rate for short-term loans from the Federal Reserve to the banks. As of May 2015, the Federal Reserve had been keeping the target rate at 0.25 percent since December 2008. When the fed funds rate rises, the prime rate rises with it. The prime rate can change from one week to the next, or it can remain the same for years. It all depends on the target federal funds rate set by the Federal Reserve, which in turn varies with the growth, or lack of growth, in the national economy.
