A Forward Rate Agreement (FRA) is a contract that establishes a fixed interest rate for a specified period between two parties, mainly used by banks for hedging against interest rate risks and speculative activities. FRAs are customized for specific needs and do not require initial margins or central clearing, with settlement reflecting the difference between the market and contract rates. The British Bankers' Association (BBA) provides standard terms for FRAs, and their applications include hedging, arbitrage, and speculation, with various types like strip FRAs and forward spread agreements becoming increasingly popular.
