Spot forex is a direct exchange of one currency for another, traded over the counter through a network of banks and brokers, with no central exchange and no expiration date. A currency future is a standardized contract on that same underlying currency, traded on a centralized exchange with a fixed expiration. Both let you speculate on currency movement, but the structure underneath is different enough to change how you’re regulated, taxed, and exposed to risk.
The core differences at a glance
| Forex | Futures | |
|---|---|---|
| What you’re trading | Currency pairs, directly | Standardized contracts on currencies, indices, commodities, and rates |
| Market structure | Decentralized, over the counter; no single official price | Centralized exchange; one cleared price for everyone |
| Trading hours | Continuous, Sunday evening through Friday evening | Nearly 24 hours via Globex, Sunday evening through Friday afternoon, with a short daily maintenance break |
| Expiration | None. Positions held overnight accrue rollover/swap charges | Contracts expire and must be rolled to maintain a position |
| Leverage | Broker-set; capped at 50:1 on major pairs under US NFA rules, often higher offshore | Exchange-set margin per contract, varies by product |
| Counterparty | Your broker or liquidity provider directly | A central clearinghouse, on every trade |
| Tax treatment | Ordinary income or loss under Section 988 by default; certain pairs can be elected into Section 1256 | Automatic Section 1256 treatment: 60% long-term, 40% short-term |
| Market coverage | Currencies only | Currencies, indices, commodities, and interest rates, in one account |
Where the price actually comes from
Forex has no central exchange. You’re trading against a broker or liquidity provider directly, and the price you see is theirs, not a single official market price. Futures trade on a centralized exchange, so every participant sees the same price, and every trade clears through the same clearinghouse. That difference is also what drives the counterparty risk gap: in forex, your counterparty is whoever you’re trading with, in futures, it’s the exchange’s clearinghouse standing behind every trade.
Leverage and regulation
US-regulated retail forex brokers are capped at 50:1 leverage on major currency pairs and 20:1 on minors, under NFA rules. Offshore brokers routinely offer far more. Futures leverage works differently: the exchange sets a fixed margin requirement per contract, based on that contract’s typical price movement, not a leverage ratio you choose. US retail forex accounts also follow rules that don’t apply to futures at all, including a FIFO requirement (closing your oldest position first when you hold multiple positions in the same pair) and a restriction on holding both a long and short position in the same pair simultaneously.
Tax treatment
Spot forex trading is taxed under Section 988 by default, treated as ordinary income or loss. Traders can elect into Section 1256 treatment for certain major currency pairs, the same 60% long-term, 40% short-term split that futures get automatically and explained in full in our guide to futures tax treatment. Which treatment actually applies, and whether electing in makes sense, depends on your specific trading pattern and is worth confirming with a tax professional rather than assuming.
One account, more markets
Forex only gives you currency exposure. Futures give you currencies, stock indices, commodities, and interest rate products, all tradable from the same account under the same margin system. For a trader who wants exposure beyond currencies, that’s a real practical difference, not just a technicality.
