What is Forward Rate Agreement?

A forward rate agreement (FRA) is a widely-used interest-rate derivative that lets parties lock in a borrowing or lending rate for a future period. It's essentially a forward contract applied to interest rates — a simple but powerful tool for managing interest-rate risk. This guide explains what a forward rate agreement is, how it works, how it's settled, and what it's used for — in clear, plain language. It complements our guide to forward rates and is relevant to anyone studying derivatives, treasury or finance.

What is a forward rate agreement?

A forward rate agreement is an over-the-counter contract in which two parties agree to exchange the difference between a fixed agreed interest rate and a reference (market) rate, on a notional amount, for a specified future period. In effect, it lets one party fix the interest rate that will apply to a future borrowing or lending, today. No actual loan is made and no principal changes hands — the notional amount is used only to calculate the payment. The FRA simply settles the difference between the rate the parties agreed and the rate that actually prevails.

How a forward rate agreement works

An FRA references a future interest period — described by notation like a "3x6 FRA", meaning a rate for a three-month period that starts in three months' time (running from month 3 to month 6). At the start of that future period, the agreed fixed rate is compared with the prevailing reference rate (a benchmark such as a SOFR-based rate). If the reference rate has risen above the agreed rate, the buyer (the party that fixed the rate, like a future borrower) receives a payment that compensates for the higher rate. If the reference rate is below the agreed rate, the buyer pays. This mirrors the position of a borrower: they're protected against rates rising.

How a forward rate agreement is settled

FRAs are cash-settled, and usually settled at the start of the reference period rather than the end. The settlement amount is the interest-rate difference applied to the notional over the period — but because it's paid at the beginning of the period (whereas the interest it represents would naturally be paid at the end), the amount is discounted back to a present value. So no principal is exchanged; only a single, discounted cash difference changes hands. This makes FRAs efficient and clean — they isolate the interest-rate risk without involving an actual loan.

A simple example

Imagine a company expects to borrow £10 million in three months for a three-month period, and worries rates will rise. It buys a 3x6 FRA fixing the rate at, say, 5%. If, in three months, the reference rate has risen to 6%, the FRA pays the company the difference (roughly 1% on £10m for three months, discounted) — offsetting the higher interest it now pays on its actual borrowing. Its effective cost is locked near 5%. If rates instead fall to 4%, the company pays out on the FRA, but benefits from cheaper actual borrowing — again ending up near 5%. Either way, the FRA has fixed its future rate.

What forward rate agreements are used for

FRAs have two main uses. The first is hedging interest-rate risk — a borrower can lock in a future borrowing cost, and a lender or investor can lock in a future return, removing uncertainty about where rates will be. The second is speculation — taking an FRA position to profit from a view on the future direction of interest rates. Because they're customisable, cash-settled and require no exchange of principal, FRAs are an efficient way to manage or take exposure to short-term interest rates, and they're a core building block of the interest-rate derivatives market.

Frequently asked questions

What is a forward rate agreement?

An OTC contract to exchange the difference between a fixed agreed interest rate and a reference rate, on a notional amount, for a future period — effectively a forward contract on an interest rate.

How does a forward rate agreement work?

It fixes a rate for a future period (e.g. a "3x6 FRA"). At the start of that period, the agreed rate is compared to the reference rate, and the difference is paid — protecting a borrower if rates rise.

How is an FRA settled?

Cash-settled at the start of the reference period, with the interest-rate difference on the notional discounted to a present value. No principal is exchanged.

What are FRAs used for?

Hedging future interest-rate risk — locking in a borrowing cost or lending return — and speculating on the future direction of interest rates.
