What Is a Forward Contract? Locking In an Exchange Rate for a Later Date

A forward contract is an agreement to exchange a set amount of one currency for another on a fixed future date, at a rate agreed today. Nothing changes hands at the start except, in many cases, a deposit or a credit check. On the settlement date the two sides swap the money at the agreed rate, whatever the market rate happens to be by then. The point is certainty: the buyer knows exactly what a future payment will cost in their own currency.

Forwards exist for commodities, shares and interest rates too, but the currency version is the one most people and small firms meet, usually when a known foreign payment sits some way in the future.

Spot versus forward

Most currency deals happen on the spot market, where money is exchanged at the current rate and settles within a couple of business days. That market, and how it is organised between banks, brokers and other participants, is outlined in the introduction to what forex trading is. A forward simply pushes the settlement date further out and fixes the price now.

	Spot transfer	Forward contract
Rate	Today's market rate	Agreed today for a later date
Settlement	Usually within two business days	On a fixed date, often weeks or months ahead
Money needed up front	The full amount	Often a deposit, the balance at settlement
Exposure to later moves	None once converted	None on the agreed amount, either way
Flexibility	Act whenever you choose	Committed to the date and amount

How the forward rate is worked out

A common assumption is that the forward rate is somebody's forecast of where the currency will be. It is not. It comes mainly from arithmetic involving the spot rate and the interest rates of the two currencies over the period of the contract.

The provider that agrees to deliver euros in six months could, in principle, buy those euros today and hold them on deposit until the date arrives. It would earn euro interest on them while giving up the interest it could have earned on the other currency. The difference between those two interest rates is built into the forward price as an adjustment known as forward points. The currency with the higher interest rate usually trades at a lower rate forward than spot, and the lower-rate currency at a higher one.

That is the same rate gap that drives much of the market's day-to-day behaviour, explained in the article on how interest rate decisions affect exchange rates. When central banks change rates, forward prices for longer dates shift too.

On top of the arithmetic sits the provider's own margin. Just as a quoted spot price has a gap between the bid and the ask, a forward quote includes a markup, and it is not always shown separately. Comparing the total amount you will receive is more useful than comparing headline rates.

Who uses forwards, and why

• Importers paying a supplier in another currency in sixty or ninety days, who want their cost price settled before they set their own selling price.
• Exporters expecting payment in a foreign currency, who want to know what that income will be worth at home.
• Property buyers with a balance due on completion. Currency risk in an overseas purchase, from deposit to resale, is walked through in exchange rate risk when buying property abroad.
• Individuals with a fixed future cost, such as school fees or a wedding abroad, where a budget matters more than catching the best possible rate.

In each case the aim is to remove uncertainty, not to make money from currency moves. Firms often describe this as hedging.

A worked illustration

Suppose a business must pay a supplier 50,000 in a foreign currency in three months. The figures below are invented to show the mechanism only.

1. Today the spot rate means the payment would cost 42,000 in the home currency.
2. The provider quotes a three-month forward rate that puts the cost at 42,300, the difference reflecting interest rates plus its margin.
3. The business agrees, pays a deposit and books the date.
4. In three months it pays the remaining balance and the supplier receives 50,000, whatever the spot rate is on the day.

If the home currency has weakened by then, the forward has saved money compared with waiting. If it has strengthened, the business pays more than it would have done at spot. Both outcomes are part of the deal: certainty runs in both directions.

What you give up

Upside from a favourable move

Once the rate is fixed, a later improvement does not help. This is the most common source of regret, and it is worth deciding beforehand that a known cost is the goal.

Flexibility on timing and amount

A standard forward is for a set sum on a set date. If a purchase falls through, the contract still has to be settled or closed out, and closing it may cost money if the rate has moved against the original deal. Some providers offer window forwards that let the money be drawn over a period, usually at a slightly less attractive rate.

Counterparty and deposit

The contract is only as good as the firm on the other side. Checking how a provider is authorised and how client money is held is part of using one, and a deposit may need topping up if the market moves sharply before settlement.

Forwards, futures and options

A future is a standardised version of a forward traded on an exchange, with fixed contract sizes and daily settlement of gains and losses. An option gives the right, but not the obligation, to exchange at a set rate, which keeps the upside at the cost of an upfront premium. A forward sits between them: tailored to the amount and date, no premium, and a firm obligation on both sides.

Questions people often ask

Does a forward rate predict where the currency is going?

No. It mainly reflects the interest rate difference between the two currencies. The real forces behind currency moves are covered in what affects exchange rates, and none of them is captured by the forward price in advance.

How far ahead can a forward be booked?

That depends on the provider; terms of a few months to a year or more are common. Longer dates usually mean a bigger deposit and wider pricing.
