CFD & Forex Trading in the United States Guide

Two bodies govern retail forex and derivatives trading in the United States: the Commodity Futures Trading Commission (CFTC), a federal agency established in 1974, and the National Futures Association (NFA), a self-regulatory organization that brokers must register with before accepting US clients. Unlike the UK's FCA or Australia's ASIC — which permit offshore brokers to serve retail clients under relatively flexible passporting rules — the CFTC requires any firm soliciting US retail forex customers to register as a Retail Foreign Exchange Dealer (RFED) or Futures Commission Merchant (FCM). Operating without that registration is a federal offense.

The practical result is that the list of CFTC-registered retail forex brokers is short. As of 2024, fewer than a dozen RFEDs hold active registration, compared to hundreds of brokers serving European or Asian markets. Offshore brokers that are not CFTC-registered are prohibited from accepting US clients, and funding an unregistered offshore account exposes traders to account seizure and legal risk.

CFDs — contracts for difference — occupy an even stricter position. The CFTC has ruled that CFDs on equities, commodities, and indices are not legal for retail traders in the US market. Whereas a UK retail trader can open a CFD on Apple stock through a standard broker, a US retail trader has no legal equivalent product. Futures and options on futures, traded on regulated exchanges like the CME, serve as the functional substitute for many instrument categories.

Retail forex trading remains permitted under CFTC oversight, but comes with a leverage cap of 50:1 on major currency pairs and 20:1 on minors — significantly lower than the 500:1 ratios sometimes advertised by offshore platforms. Verify current registration status of any broker at nfa.futures.org before depositing funds.

Given the CFD ban, US retail traders work with a different toolkit than their counterparts in Europe or Asia. Spot forex remains the most accessible market, with EUR/USD, GBP/USD, USD/JPY, and other major pairs available through CFTC-registered platforms. Spreads on EUR/USD from registered US brokers typically run 0.5 to 2 pips depending on account type, compared to the sub-0.5 pip raw spreads available through offshore ECN brokers in less regulated jurisdictions — a real cost difference for high-frequency traders.

Futures contracts traded on the CME Group exchanges fill the gap left by CFDs. E-mini S&P 500 futures (ES), crude oil futures (CL), gold futures (GC), and currency futures all provide leveraged exposure to assets that would otherwise require CFDs in other markets. The minimum tick value on an ES contract is $12.50, making position sizing more rigid than spot forex, but exchange-traded futures carry counterparty protection that OTC instruments do not.

Options on futures add another dimension. A trader wanting exposure to gold price movements can trade GC options on the CME rather than a gold CFD. The mechanics differ — options require understanding premium, delta, and expiry — but the underlying market access is comparable.

Binary options, once marketed heavily to US retail traders, are banned for retail use under CFTC rules. Any platform offering binary options to US residents without CFTC registration is operating illegally, regardless of where it is incorporated.

Tax treatment in the US depends heavily on which instrument you trade — a distinction that can shift your effective tax rate by 10 percentage points or more.

Spot forex trades fall under Section 988 of the Internal Revenue Code by default. Under Section 988, all gains and losses are treated as ordinary income, taxed at your marginal rate, which can reach 37% for high earners in 2024. Compared to long-term capital gains rates of 0%, 15%, or 20%, this is a significant disadvantage for profitable traders.

Futures contracts and certain forex options qualify as Section 1256 contracts, which receive a more favorable blended treatment: 60% of gains are taxed at the long-term capital gains rate and 40% at the short-term (ordinary income) rate, regardless of how long the position was held. For a trader in the 32% ordinary income bracket with a 15% long-term rate, the blended Section 1256 rate works out to roughly 22.8% — a meaningful difference on a $50,000 gain.

Spot forex traders can elect out of Section 988 treatment and into capital gains treatment, but this election must be made before the trade, not at tax time. The mechanics of this election and its implications are nuanced. Consult a tax professional familiar with trader tax status before making any elections — the IRS has specific documentation requirements, and errors are difficult to correct retroactively.

Wash sale rules that apply to stocks do not apply to futures, giving futures traders more flexibility in harvesting losses near year-end. Mark-to-market accounting rules also apply to Section 1256 contracts, meaning open positions are treated as closed on December 31 for tax purposes each year.
