In short
- UK retail leverage is capped at 30:1 on major FX pairs.
- Brokers must close positions at 50% margin and provide negative balance protection.
- Professional clients can access higher leverage but lose some protections.
What leverage is
Leverage lets you control a larger position than the money you put up. With 30:1 leverage, £1,000 of margin controls a position worth £30,000. Profits and losses are calculated on the full £30,000 — which is why leverage magnifies both.
FCA leverage limits for retail clients
| Asset | Max leverage | Margin required |
|---|---|---|
| Major currency pairs | 30:1 | 3.33% |
| Non-major currency pairs, gold, major indices | 20:1 | 5% |
| Commodities (excl. gold), non-major indices | 10:1 | 10% |
| Individual shares | 5:1 | 20% |
| Cryptocurrencies | Crypto CFDs banned for UK retail clients | |
Major pairs are those combining two of USD, EUR, JPY, GBP, CAD and CHF.
Margin in practice
To open one standard lot of GBP/USD (100,000 GBP) at 30:1, you need margin of £100,000 ÷ 30 ≈ £3,333. A move of 1% against you — about 127 pips — would cost roughly £1,000, or 30% of that margin.
Other retail protections
- Margin close-out at 50%: positions are closed when equity falls to half of required margin.
- Negative balance protection: you can't lose more than the funds in your account.
- No incentives: brokers can't offer bonuses to retail CFD clients.
- Standardised risk warning showing the share of retail accounts that lose money.
Professional client status
Experienced traders can ask to be treated as professional clients, which lifts the leverage caps. You normally need to meet two of three tests: significant trading activity (around 10 sizeable trades per quarter over the last year), a financial portfolio over €500,000, or at least a year's relevant professional experience in finance. You give up retail protections such as the leverage limits and may lose negative balance protection and Ombudsman access depending on the firm.
Choosing your own leverage
The cap is a maximum, not a target. Many experienced traders size positions so that a stop-loss would cost no more than 1–2% of their account, which usually means using far less than 30:1.
Leverage, margin and position size compared
How much margin different GBP/USD positions need under the FCA's 30:1 retail limit, with GBP/USD at 1.27:
| Position | Notional value | Margin at 30:1 | P&L for a 50-pip move |
|---|---|---|---|
| 0.01 lot (micro) | £1,000 | ≈ £33 | ≈ £3.94 |
| 0.1 lot (mini) | £10,000 | ≈ £333 | ≈ £39 |
| 1 lot (standard) | £100,000 | ≈ £3,333 | ≈ £394 |
Effective leverage: the number that really matters
The maximum leverage the broker allows isn't the leverage you actually use. Effective leverage = total position value ÷ account equity. If you hold a £10,000 position in a £2,000 account, your effective leverage is 5:1, regardless of the 30:1 cap. Keeping effective leverage low is one of the simplest ways to survive volatile markets.
A margin close-out, step by step
- You deposit £1,000 and buy 0.25 lots of GBP/USD (£25,000 notional). Required margin at 30:1 ≈ £833.
- The trade moves against you by about 70 pips — a loss of roughly £138 — so equity falls to around £862.
- If losses continue and equity falls to about £417 — 50% of the required £833 — the broker must close the position.
- You keep the remaining equity, and negative balance protection means you can't end up owing money.
The lesson: opening positions close to your maximum margin leaves almost no room for normal price swings.
