The short version
- A currency future is an agreement, traded on an exchange, to exchange a fixed amount of currency at a set price on a set date.
- Contracts are standardised and cleared centrally, with gains and losses settled every day.
- They are leveraged: a small margin controls a large position, so losses can exceed what you first put down.
Forex futures are contracts to buy or sell a fixed amount of one currency for another at a price agreed today, for exchange on a set date in the future. Unlike the spot forex that most retail brokers quote, they trade on a regulated futures exchange, in standard sizes and with a clearing house standing between buyer and seller. Companies use them to lock in exchange rates; traders use them to speculate on the direction of a currency.
How a currency future works
Every contract on a given currency has the same specification: the amount of currency, the minimum price step (the tick), the expiry months and how it settles. That standardisation is what allows thousands of participants to trade the same contract on one central order book.
On CME Group, the main US futures exchange, the standard euro contract covers 125,000 euros and is priced in US dollars per euro. The minimum tick of 0.00005 is worth 125,000 × 0.00005 = $6.25. Standard contracts expire quarterly, in March, June, September and December, and smaller E-mini and E-micro versions exist for lower exposure; the micro contract's minimum tick is worth $1.25.
Illustrative example. You buy one standard euro contract at 1.0850 and the price rises to 1.0900. The move of 0.0050 is 100 ticks, worth 100 × $6.25 = $625, which is the same as 125,000 × 0.0050. Had the price fallen by the same amount, you would have lost $625 before fees.
Margin and daily settlement
You do not pay the full value of the contract. Instead the exchange sets an initial margin, a deposit per contract, and a lower maintenance margin. At the end of each trading day, every open position is marked to the day's settlement price and gains or losses are moved in cash between accounts. If losses push your balance below the maintenance level, your broker issues a margin call and you must add money, or the position will be closed.
This daily settlement is one of the key differences from a spot position: losses are not left to build up until you close. The clearing house also guarantees each side of the trade, which removes the risk that the party on the other side fails to pay.
FX futures compared with spot forex and CFDs
| FX futures | Retail spot forex / CFDs | |
|---|---|---|
| Where it trades | A regulated exchange, one central order book | Over the counter, against the broker's price |
| Contract size | Fixed by the exchange | Flexible, down to micro lots |
| Expiry | Set dates; positions must be closed or rolled | No expiry; overnight swap charged instead |
| Price | Spot rate adjusted for the interest-rate gap until expiry | Close to the spot rate |
| Counterparty | Clearing house | The broker |
| Costs | Exchange and broker commissions, plus the spread | Spread, possible commission and daily financing |
The futures price is not the same as today's exchange rate. It reflects the spot rate plus or minus the difference between the two currencies' interest rates over the life of the contract, because holding one currency instead of the other earns or costs that interest. As expiry approaches, the gap shrinks towards zero.
Trading hours and the morning picture
Currency futures trade almost around the clock. The euro contract, for example, trades from Sunday to Friday, 17:00 to 16:00 Central Time, with a one-hour break each afternoon. Stock index futures follow a similar near-continuous schedule, which is why they are watched overnight as a signal of how the next cash session may open.
That has a practical consequence for new investors. When you open a share market today live page before the opening bell, many of the moving numbers are futures prices or pre-market indications rather than the index itself. They show expectations, and they can reverse sharply once the exchange opens and full trading begins. Our Nasdaq index guide explains how the cash index is calculated during the session.
Who uses forex futures, and why
- Hedgers: an importer due to pay suppliers in euros in three months can buy euro futures now, fixing the exchange rate and removing the uncertainty from its budget.
- Investors with foreign assets: fund managers may sell currency futures to reduce the effect of exchange-rate swings on overseas holdings.
- Speculators: traders take positions on expected currency moves, adding liquidity but also bearing the full leveraged risk.
Expiry, delivery and rolling
Many currency futures are settled at expiry by actual delivery of the currencies. Most speculators never want that, so they close the position before the last trading day, or roll it: closing the expiring contract and opening the next one. Each roll has a cost in commissions and the spread, and the price difference between the two contracts reflects the interest-rate gap.
Risks to understand before trading
- Leverage: the full contract value moves with the market, not just your margin.
- Margin calls: daily settlement can demand cash quickly after a bad day.
- Gaps: news during the daily break or over a weekend can move prices past a stop order.
- Contract size: even the smaller versions represent large sums relative to many personal accounts.
In the US, futures brokers must be registered with the Commodity Futures Trading Commission and be members of the National Futures Association; check the registration of any firm before opening an account.

Reader questions
Are forex futures the same as forex CFDs?
No. Futures trade on a regulated exchange in standard sizes with fixed expiry dates and a clearing house, while CFDs are private contracts with a broker that have no expiry and charge overnight financing instead.
Do I have to take delivery of the currency?
Not if you close or roll the position before the last trading day. Many currency futures are physically delivered at expiry, so speculators normally exit beforehand.
Why is the futures price different from the spot rate?
The futures price reflects the interest-rate difference between the two currencies until expiry. The gap narrows as the contract approaches its expiry date.
