UK Forex Leverage Limits Explained: 30:1, 20:1 and the Rest

The UK forex leverage limit for a retail client is 30:1 on major currency pairs, which means you must put up at least 3.33% of the position’s value as margin. Minor pairs and gold are capped at 20:1 (5% margin). Those caps come from the FCA’s permanent CFD rules in COBS 22.5, in force since 1 August 2019, and they apply equally to CFDs, spread bets and rolling spot forex. A UK-authorised firm can offer you less leverage than this, never more, unless you are classed as a professional client.

The full FCA margin table

The FCA sets the rule as a minimum initial margin, a percentage of the notional value of the trade. Leverage is just the other way of writing the same number: 3.33% margin is 30:1, 5% is 20:1 and so on. Your broker will usually show leverage on the account page and margin on the trade ticket, so it helps to be able to flip between the two.

The source is COBS 22.5.11R in the FCA Handbook. When the FCA made the rules permanent in July 2019 it spelled out that references to CFDs include financial spread bets and rolling spot forex. So there is no loophole in switching product. A £10-per-point spread bet on cable carries the same 3.33% floor as a one-lot CFD on MT5.

Crypto is the odd one out. The FCA banned the sale of crypto derivatives to retail clients from 6 January 2021 and that ban still stands. A separate change in October 2025 let retail investors buy crypto exchange traded notes listed on UK exchanges, which is a different product altogether. Any UK broker offering you leveraged bitcoin CFDs as a retail client is not following the rules.

What counts as a major pair

A major pair is any pair made up of two of these six currencies: US dollar, euro, Japanese yen, pound sterling, Canadian dollar and Swiss franc. That follows the convention the FCA inherited from the EU rules. Everything else is a non-major pair and drops to 20:1.

That list surprises people in both directions. EUR/GBP, GBP/JPY, GBP/CHF and CAD/JPY all count as majors, even though traders often call some of them crosses. AUD/USD and NZD/USD do not, because the Australian and New Zealand dollars are not on the list. So a UK trader gets 30:1 on GBP/CAD but only 20:1 on the Aussie. Pairs from emerging markets, such as USD/ZAR, USD/TRY or USD/MXN also sit at 20:1, and some firms set their own lower limits on them because spreads and gaps are wider.

Major stock indices have their own list in the FCA Glossary: the FTSE 100, CAC 40, DAX, Dow Jones Industrial Average, S&P 500, NASDAQ Composite, NASDAQ 100, Nikkei 225, ASX 200 and EURO STOXX 50. Those get 20:1. A smaller index, such as the FTSE 250, falls to 10:1.

Worked margin examples in pounds

Margin is easiest to follow with real numbers. Take one standard lot of GBP/USD, which is £100,000 of sterling, bought at a price of about 1.3400. The position is worth $134,000. If your account is in pounds, the notional in your own currency is simply £100,000, because you are buying pounds.

1. Notional value: 1 lot = £100,000 (or $134,000 at 1.3400).
2. Retail margin at 30:1: £100,000 ÷ 30 = £3,333 (the same as 3.33% of £100,000).
3. Pip value: one pip on a standard lot of GBP/USD is $10, roughly £7.46 at 1.3400.
4. Effect of a 100-pip move: about £746 profit or loss, or 22% of the margin you put up.

Now shrink it to something closer to what a new trader would place. A mini lot (0.1) of GBP/USD is £10,000 notional, so the margin is about £333 and each pip is worth around 75p. Spread bets work in pounds per point, and one point on cable is one pip. A £1-per-point bet at 1.3400 has a notional value of 13,400 points × £1, or £13,400, so the 3.33% margin is about £447. Each pip is worth exactly £1, a little more than the 75p on a mini lot.

For a minor pair, the maths moves up. One standard lot of AUD/USD is A$100,000. At an illustrative AUD/GBP rate of about 0.53, that is roughly £53,000 notional, and at 20:1 you need around £2,650 of margin. Had AUD been a major, 30:1 would have meant about £1,770.

How the UK compares with offshore brokers

Offshore brokers licensed in places such as Seychelles, St Vincent, Vanuatu or the Bahamas are not bound by COBS 22.5, and many advertise leverage of 500:1, 1000:1 or more. IC Markets (now trading as IC), for example, advertises up to 1:5000 on MT4 and MT5 and 1:1000 on cTrader through its Seychelles entity, with tiers and higher margins around news and weekends. It holds no FCA authorisation and the FCA has a Warning List entry against it, which we cover in our IC Markets leverage article.

The professional figures in that table are typical broker offers, not an FCA number, since there is no statutory cap for professional clients. What matters in the comparison is the last column. At 1000:1 a normal morning’s wobble in cable can wipe out the whole margin on the trade. Lower margin also means you can open far bigger positions than your account can survive, and that is where the damage is done.

Other large regulators went the same way as the UK. The EU rules the FCA copied in 2018 use the same table, and Australia’s ASIC brought in 30:1 on majors for retail clients in 2021. So the UK is not an outlier here. High leverage is now mostly an offshore product, and it comes without the FCA’s other protections, including negative balance protection and access to the Financial Ombudsman.

Why the caps exist

The FCA restricted leverage after years of evidence that most retail CFD accounts lost money, and that losses rose with leverage. They arrived as a package: leverage limits, a 50% margin close-out rule and negative balance protection, a ban on bonuses and trading incentives, and a standard risk warning that forces every firm to publish the share of its retail accounts that lose money, updated each quarter.

Those warnings still make sobering reading. At the time of writing (September 2026), IG’s UK figure is 69%, Pepperstone’s is 72.9% and XTB’s is 74%. Even with lower leverage, most retail accounts still lose. Think of the cap as a seat belt rather than a strategy: it slows down how fast a bad habit empties an account, which gives you more time to notice.

A second reason is gaps. When a price jumps over your stop, such as at a weekend open or on a surprise central bank decision, the size of your loss depends on the size of your position. A 3.33% margin floor keeps positions in proportion to the account, so a single shock is less likely to take you below zero.

Ways traders get around the cap, and the catch

There are three common routes, and each costs you something.

• Elective professional status. A UK firm can lift the caps if you pass the COBS 3.5.3R tests and ask in writing. You lose the retail protections at the same time. Our professional client guide sets out the criteria and what changes.
• An offshore account. Nothing stops a UK resident from opening one, but you lose FCA conduct rules, the Ombudsman and the FSCS, and disputes go to foreign courts. See our piece on offshore brokers for UK residents.
• Bigger deposits. This is the honest route. A £6,000 account can hold the margin on one lot of cable with room left for adverse moves. It also exposes you to £6,000 of risk, so size the account to what you can afford to lose.

How to check the leverage on your account

Open the contract specifications or market info panel for the pair on your platform. It will show the margin rate, often as a percentage. On MT4 and MT5 it may appear as the account leverage (1:30) combined with a per-symbol margin percentage. Spread betting platforms tend to show it as a margin factor next to the market. If you see figures below 3.33% on a major pair and you are a retail client, ask the firm why, and check which entity holds your account on the FCA Register.

Firms can and do set stricter limits than the FCA minimum, especially on exotic pairs and ahead of events such as general elections or Bank of England decisions. That is allowed. What a UK retail account cannot do is give you more.
