Who regulates forex in the UK?
The Financial Conduct Authority regulates firms that offer forex and CFD trading to UK residents. Under the Financial Services and Markets Act 2000, firms must be authorised by the FCA to carry on regulated investment activities in the UK. Each authorised firm has a Firm Reference Number (FRN) you can look up on the FCA's Financial Services Register.
How UK retail traders actually trade forex
Most individuals don't buy currencies outright. They use leveraged derivatives offered by brokers:
- CFDs (contracts for difference) — you trade the price difference of a currency pair without owning it.
- Spread bets — a UK-specific product where you stake an amount per point of movement.
Both are legal and regulated, and both carry a high risk of losing money.
Rules that protect retail traders
Since 2019 the FCA has applied permanent product rules to CFDs and spread bets sold to retail clients:
| Rule | What it means |
|---|---|
| Leverage limits | 30:1 on major FX pairs, 20:1 on minors, gold and major indices, down to 5:1 on shares |
| Margin close-out | Positions closed when equity falls to 50% of required margin |
| Negative balance protection | You can't lose more than the money in your account |
| No incentives | Bonuses and trading incentives are banned |
| Risk warning | Firms must show the percentage of their retail accounts that lose money |
What's banned for UK retail clients
- Cryptocurrency derivatives (CFDs, futures, options and ETNs on crypto) — banned for retail consumers since January 2021.
- Binary options — banned for retail consumers since 2019.
If a firm offers these to you as a UK retail client, it's a strong sign it's not FCA-authorised or is onboarding you through an offshore entity.
How to stay safe
- Check the firm on the FCA register and confirm the contact details match.
- Read the client agreement to see which legal entity will hold your account.
- Be wary of unsolicited contact, guaranteed returns and pressure to deposit.
- Remember that profits may be taxable — see our forex tax guide.
Timeline: how UK rules have changed
| Year | Change |
|---|---|
| 2018 | ESMA introduces temporary EU-wide restrictions on CFDs and a ban on binary options for retail clients, which apply in the UK. |
| 2019 | The FCA makes its own permanent rules for retail CFDs and spread bets (leverage limits, margin close-out, negative balance protection, ban on incentives) and permanently bans binary options for retail consumers. |
| 2021 | The FCA bans the sale of crypto-asset derivatives to retail consumers. The Brexit transition ends, and EU firms lose passporting rights into the UK. |
| 2023 | The FCA's Consumer Duty raises the bar for how firms treat retail customers, including fair value and clear communications. |
The Consumer Duty and what it means for traders
Since July 2023, FCA-authorised firms must act to deliver good outcomes for retail customers. For CFD brokers, that means products should offer fair value, communications should be clear and not misleading, customers shouldn't face unreasonable barriers (for example, when withdrawing money or closing an account), and support should meet customers' needs. If a broker's behaviour falls short, it's relevant to any complaint you make.
Promotions and "finfluencers"
Financial promotions for CFDs must be fair, clear and not misleading, and must carry the standard risk warning. People promoting trading on social media without being authorised or approved can break the law, and the FCA has taken action against unauthorised "finfluencers". Treat lifestyle-style trading promotions with scepticism and check who is behind them.
Legal vs suitable
Something being legal doesn't make it suitable for you. FCA brokers must assess whether CFDs are appropriate for you based on your knowledge and experience, and they must warn you if they're not. Take those warnings seriously — and remember that most retail CFD accounts lose money.
