Sign up at an offshore broker with a US address and the form stops. That refusal is the visible end of a regime built after 2008 that treats retail foreign exchange as a federally regulated activity with its own registration category, its own capital floor and its own order handling rules. Very few firms choose to operate inside it.
Two bodies, different jobs
The Commodity Futures Trading Commission is the federal agency with statutory authority over commodity futures, options and retail off-exchange foreign exchange. It writes the rules and brings enforcement actions. The National Futures Association is the industry self-regulatory organisation: membership is compulsory for registered firms, and it runs the examinations, the compliance rulebook, the arbitration forum and the public register.
A firm acting as counterparty to retail forex customers registers with the CFTC, commonly as a retail foreign exchange dealer or as a futures commission merchant, and must also be an NFA member. Introducing brokers, commodity trading advisors and account managers have their own registration categories, and individuals dealing with the public are registered as associated persons after proficiency testing and a background check.
The rules a trader actually feels
| Rule | Effect on the account |
|---|---|
| Security deposit minimums | Leverage capped near 50:1 on major currency pairs and 20:1 on other pairs |
| FIFO offsetting | Closing part of an exposure closes the oldest lot in that pair first |
| No opposing positions | A long and a short in the same pair cannot coexist; the second order offsets the first |
| Dealer registration | Only registered counterparties may offer retail forex to US persons |
| Instrument scope | Retail CFDs on shares and indices are not available; equivalent exposure trades as listed futures or options |
The hedging prohibition confuses traders arriving from other regimes, because platforms elsewhere let a client hold both directions at once. Economically that combination is a closed position paying two spreads, so the rule removes something that was never a strategy, however much it is marketed as one in hedging discussions.
FIFO has a real cost for scaling in. A trader who adds to a position three times and wants to take profit on the newest lot cannot do it; the oldest lot goes first. Any strategy that depends on managing individual entries separately has to be rebuilt around a single net position.
Capital, and why the field is small
Retail forex dealers carry an adjusted net capital requirement in the tens of millions of dollars, with additional amounts tied to the size of customer liabilities. Compare that with jurisdictions where a derivatives licence starts in the low hundreds of thousands and the outcome follows: a handful of firms serve the entire US retail forex market, against dozens in Cyprus or Australia.
Reporting matches the capital. Registered firms file financial statements on a defined cycle, publish certain customer-account metrics, submit to periodic examination and hold customer funds under the applicable segregation and secured-amount requirements. Advertising is reviewed, and performance claims in promotional material draw attention quickly. Our note on capital requirements for brokers puts the numbers side by side across regimes.
Registration is a statement about supervision, not about outcomes. Leveraged forex carries a high risk of loss under any regulator, and US rules do not include a European-style mandate for negative balance protection, so a firm's own policy governs what happens if an account goes below zero on a gap.
What a US resident can and cannot access
Spot forex through a registered dealer is available with the leverage caps above. Futures and options on futures trade on designated contract markets through a futures commission merchant, which is how most US traders get index and commodity exposure. Retail contracts for difference on shares and indices are not offered, because the product structure does not fit the exchange-traded framework the US applies to those markets.
Leveraged retail transactions in metals sit under specific restrictions as well, which is why offers of leveraged gold trading to US retail clients from unregistered venues attract enforcement attention. A trader comparing an offshore account with a domestic one is comparing two different legal products, a distinction we cover in regulated versus unregulated brokers.
The registration net is wider than the dealers themselves. A person soliciting orders without holding customer funds registers as an introducing broker, someone managing accounts or selling trading advice for compensation may fall into the commodity trading advisor category, and individuals in client-facing roles register as associated persons. Disputes have their own route as well, through the NFA arbitration forum, which gives customers a defined process that offshore accounts generally do not offer.
Checking a firm, and the reverse solicitation myth
NFA BASIC is the public database for registration status and disciplinary history. Search the legal entity, confirm the registration category and current membership, and read the regulatory actions section rather than skipping to the green tick. Then compare the entity name against the counterparty on the client agreement, the same verification described in how to check a broker licence.
The argument that a US resident may simply approach a foreign broker of their own initiative gets repeated in forums as though it settles the question. It does not settle it for the firm: acting as an unregistered counterparty to US persons is the exposure, and the client's initiative does not cure it. For an operator planning market entry, the honest advice is that the US is a deliberate, capital-heavy decision made in advance, never a market you drift into because sign-ups arrived. Firms outside the regime should geo-block properly and document that they do.
"Every few months an operator asks us how to take American clients quietly. The answer is that there is no quiet version. You register and you fund the balance sheet, or you block the country properly."

Key Takeaways
- The CFTC writes the rules for retail off-exchange forex and the NFA enforces the compliance rulebook and registers member firms and individuals.
- Security deposit minimums cap retail leverage near 50:1 on majors and 20:1 on other pairs.
- FIFO offsetting and the ban on opposing positions change how a strategy scales in and out of exposure.
- Capital requirements in the tens of millions keep the number of registered retail forex dealers very small.
Frequently Asked Questions
Why do offshore brokers refuse US residents?
Offering retail forex to persons in the United States requires registration with the CFTC and membership of the NFA, and the capital and reporting obligations attached to that status are far heavier than in most other jurisdictions. Firms that do not intend to register block US residents at sign-up to avoid acting as an unregistered dealer.
What is the FIFO rule in US forex?
Under NFA rules, when a customer holds multiple positions in the same currency pair and closes part of the exposure, the oldest position must be offset first. The practical effect is that a trader cannot pick which of several open lots to close, and cannot hold an opposing position in the same pair at the same time.
How do I check whether a US forex firm is registered?
Search the firm in NFA BASIC, the public database of registration and disciplinary information. Check the registration category, whether NFA membership is current, and the regulatory actions section. Compare the legal entity name against the entity on the client agreement rather than the trading brand shown on the website.
