What does forex regulation cover?

Retail forex is usually traded over the counter, with the broker as the client’s counterparty or intermediary, so the rules that protect clients come from the regulator that licenses the broker. Forex regulation typically covers:

• Authorisation: which firms may offer leveraged forex to retail clients in a country, and the capital, reporting and conduct standards they must meet.
• Leverage limits: the maximum leverage, or minimum margin, for retail clients: what is leverage in forex.
• Client money: whether client funds must be held separately from the firm’s own money: segregated client funds.
• Loss protections: margin close-out rules and negative balance protection.
• Marketing and conduct: risk warnings, restrictions on bonuses and other incentives, and complaint handling.

There is no single global forex regulator. Each licence applies to a specific legal entity and to the clients that entity is permitted to serve, which is why a regulated forex broker in one country may not be authorised to serve residents of another: how to choose a forex broker.

Forex regulators and leverage limits by country

The table compares the main regulators and the retail leverage cap on major currencies, as of October 2026. Rules change, and caps for other instruments are usually lower.

Country or region	Main regulator(s)	Retail leverage cap, major currencies	Notes
United States	CFTC, NFA	50:1 on specified major currencies (2% minimum security deposit)	5% minimum security deposit (20:1) on other currencies; FIFO rule for offsetting positions
United Kingdom	FCA	30:1 for CFDs sold to retail clients	Margin close-out at 50%, negative balance protection, incentives restricted
European Union	National competent authorities, e.g. CySEC (Cyprus), BaFin (Germany)	30:1 for CFDs sold to retail clients	ESMA introduced the measures in 2018; national competent authorities subsequently adopted permanent measures
Australia	ASIC	30:1 for CFDs sold to retail clients	Product intervention order currently due to expire on 23 May 2027 unless remade
Japan	FSA, with FFAJ rules	25:1 for individual customers (4% minimum margin)	In force since 1 August 2011; different rules apply to corporate customers
Turkey	SPK (Capital Markets Board)	10:1 at position opening	Minimum initial deposit of 50,000 Turkish lira or equivalent; only SPK-authorised firms may serve Turkish residents

Margin for the same position under different caps (illustrative only)

Assumption: the broker applies the maximum retail leverage the regulator allows. A regulator’s cap is an upper limit; a broker may offer lower leverage. Other assumptions: EUR/USD, 1 standard lot (100,000 euros), price 1.1000, so the position is worth $110,000; USD account.

• 50:1 (US): $110,000 ÷ 50 = $2,200
• 30:1 (UK, EU, Australia): $110,000 ÷ 30 = about $3,667
• 25:1 (Japan): $110,000 ÷ 25 = $4,400
• 10:1 (Turkey): $110,000 ÷ 10 = $11,000

For the same position size, the leverage cap changes the margin needed to open the position, not the profit or loss per pip, which is about $10 per standard lot in each case.

How is forex regulated in the US (CFTC and NFA)?

Under CFTC forex regulation, only certain regulated entities may act as the counterparty to retail forex trades, mainly a retail foreign exchange dealer (RFED) or a futures commission merchant (FCM). Both must be NFA members approved for forex, and the CFTC advises checking registration before opening an account.

NFA rules set minimum security deposits of 2% of notional value on specified major currencies and 5% on others. Separately, a forex dealer member may not carry offsetting positions in a customer account and must offset them on a first-in, first-out (FIFO) basis. In practice, this means opposite long and short positions in the same pair cannot be held open side by side in one account in the way many platforms outside the US allow: hedging.

How is forex regulated in the UK (FCA)?

Under FCA forex regulation, CFDs sold to retail clients, including rolling spot forex, are subject to leverage limits from 30:1 to 2:1 depending on the underlying, margin close-out at 50% of required margin, negative balance protection, a ban on cash and other incentives to trade, and standardised risk warnings showing the percentage of the firm’s retail accounts that lose money. The rules apply to retail clients; clients classified as professional are treated differently.

How is forex regulated in the EU?

In the EU, ESMA introduced temporary product intervention measures on CFDs for retail clients in 2018, including a 30:1 cap on major currency pairs, margin close-out at 50% and negative balance protection. After those measures expired in 2019, national competent authorities such as CySEC in Cyprus and BaFin in Germany adopted their own permanent measures, so the details are set country by country.

How is forex regulated in Australia and Japan?

Under ASIC forex regulation, a product intervention order in force since 29 March 2021 limits retail CFD leverage to 30:1 on major currency pairs and adds margin close-out, negative balance protection and restrictions on inducements; the order is currently due to expire on 23 May 2027 unless remade. In Japan, FFAJ rules require a minimum margin of 4% of the trading amount for individual customers, which caps their leverage at 25:1.

What is an offshore forex broker?

An offshore forex broker is an entity licensed in a jurisdiction other than the client’s own. Many broker groups run several entities in different jurisdictions, and jurisdictions may differ in capital requirements, leverage limits, client money rules, complaint mechanisms and compensation arrangements. An offshore entity may offer higher leverage and may provide different or more limited protections depending on the jurisdiction. Some firms are not regulated at all and only claim to be; the warning signs are covered in forex scams, and impersonation of authorised firms in clone firm.

For Turkey, retail leveraged trading is reserved for SPK-authorised firms; the Turkish rules are explained in SPK forex leverage limit (in Turkish).

How do you check if a forex broker is regulated by a specific regulator?

A broker licence check uses the regulator register itself: search for the exact legal name or registration number of the entity on the regulator’s official register, and check that the website and contact details match the register entry. For a forex broker regulation check in the US, NFA BASIC shows registration and disciplinary history, and the CFTC’s RED list names foreign entities that appear to need CFTC registration but are not registered. Whether trading forex is permitted for residents of a given country is a separate question: is forex trading legal.
