Prime rate or prime lending rate is a term applied in many countries to reference an interest rate used by banks. The term originally indicated the interest rate at which banks lent to favored customersâi.e., those with good creditâbut this is no longer always the case.
The target federal funds rate, which is set by the Federal Reserve Board, serves as the basis for the prime rate. The federal funds rate is the interest rate commercial banks charge each other for overnight lending. Generally, the prime rate is about 3 percent higher than the federal funds rate. That means that when the Fed raises interest rates, the prime rate also goes up. Banks use the prime rate to set interest rates on numerous short-term loan products.
