A forward rate agreement (FRA) is an interbank-traded contract to buy or sell interest rate payments on a national principal. These contracts are settled in cash. The buyer of an FRA obtains the right to lock in an interest rate for a desired term that begins at a future date. The contract specifies that the seller of the FRA will pay the buyer the increased interest expense on a nominal sum (the national principal) of money if interest rates rise above the agreed rate, but the buyer will pay the seller the differential interest expense if interest rates fall below the agreed rate. Maturities available are typically 1, 3, 6, 9 and 12 months, much like traditional forward contracts for currencies.
