ESMA leverage limits and negative balance protection, explained

If you trade CFDs or forex with a broker regulated in the EU or UK as a retail client, your leverage is capped by law: 30:1 on major currency pairs, falling to 2:1 on cryptocurrencies. On top of that, your broker must close your positions when your account equity falls to half of the margin required, and you can never lose more than the money in your account. These rules come from the European Securities and Markets Authority (ESMA) and were copied, almost word for word, by national regulators including the FCA and CySEC.

This guide explains what each rule does, why regulators introduced them, how they show up in your account day to day, and what changes if you trade with a firm outside these regimes or apply for professional status.

Where the rules came from

By 2017 European regulators had a large and growing problem. Online CFD and binary options providers were marketing aggressively across borders, often from a single licence, with leverage of 200:1, 400:1 or higher, sign-up incentives and very little friction. National regulators that looked at their own firms kept finding the same thing: most retail accounts lost money.

In March 2018 ESMA used new powers it had been given under MiFIR (the regulation that accompanies MiFID II) to intervene directly in the product. In its press release of 27 March 2018, ESMA said national regulators' analyses showed that 74% to 89% of retail accounts typically lose money on CFDs, with average losses per client ranging from €1,600 to €29,000. It announced a ban on selling binary options to retail clients and a package of restrictions on CFDs, which applied from 1 August 2018.

ESMA's powers were temporary: it could only impose these measures for three months at a time and had to renew them repeatedly. During 2019 national regulators across the EU adopted the same rules permanently into their own law, and ESMA let its own CFD measure lapse at the end of July 2019. The practical result for traders did not change. The rules simply moved from an EU-level decision to national rulebooks.

• Cyprus (CySEC): adopted national measures in 2019 matching ESMA's leverage limits for all retail clients, after consulting on, and dropping, a tiered alternative.
• United Kingdom (FCA): made the restrictions permanent for CFDs from 1 August 2019. They continue to apply after Brexit as part of the FCA's own rules.
• Other EU states: France, Germany, Spain, Italy, Ireland and the rest adopted equivalent measures, some slightly stricter (for example, with extra restrictions on marketing).

The five protections in one list

The ESMA package has five parts. Every regulated EU or UK broker has to apply them to retail clients.

1. Leverage limits on opening positions, set by how volatile the underlying asset is.
2. A margin close-out rule on a per-account basis: positions must be closed when equity falls to 50% of the required margin.
3. Negative balance protection on a per-account basis: a retail client cannot lose more than the funds in their CFD account.
4. A ban on incentives to trade, such as deposit matches or gifts.
5. A standardised risk warning that states the percentage of the firm's own retail accounts that lose money.

We will take them one at a time, because each one changes something real about how you trade.

The leverage caps

Leverage is the ratio between the size of the position you control and the margin you put up. If you are new to the mechanics, read our guide to leverage and margin first; the short version is that 30:1 leverage means you need 1/30 of the position value, or about 3.33%, as margin.

The ESMA caps for retail clients are:

• 30:1 (3.33% margin) on major currency pairs. The majors are any pair made of two of USD, EUR, JPY, GBP, CAD and CHF.
• 20:1 (5% margin) on non-major currency pairs, gold and major equity indices.
• 10:1 (10% margin) on commodities other than gold and on non-major equity indices.
• 5:1 (20% margin) on individual shares and other reference values.
• 2:1 (50% margin) on cryptocurrencies.

Note what counts as a major. AUD/USD and NZD/USD are not majors under the ESMA definition, because AUD and NZD are not on the list, so they carry a 20:1 cap. EUR/GBP, EUR/JPY, GBP/JPY and USD/CHF are majors at 30:1. If you want a refresher on how pairs are classified more generally, see currency pairs explained.

What the caps do and do not limit

The caps limit the maximum leverage on a new position, which means they set a minimum margin. They do not stop you from taking a large position: if you have enough money, you can open whatever size you like. What they do is force you to post more collateral for each unit of exposure, which slows the speed at which a small account can be wiped out.

They also do not limit your effective leverage on the account as a whole. If you deposit £1,000 and open a £30,000 EUR/USD position, the margin used is £1,000 and your effective leverage is 30:1. If you then open a second position on GBP/USD, you cannot, because you have no free margin left. The cap works through the margin requirement, so the more of your balance you commit, the closer you get to the edge.

Worked example: same trade, different leverage

Illustrative numbers. You have €2,000 in your account and want to buy one standard lot of EUR/USD (100,000 euros) at 1.1000. The position is worth about $110,000, or €100,000.

• At 30:1 the broker requires €100,000 / 30 = €3,333 of margin. You do not have it. You cannot open a full standard lot; the most you can open is roughly 0.6 lots, which needs about €2,000 and leaves almost no free margin.
• At 400:1 (common offshore) the margin would be €100,000 / 400 = €250. You could open the full lot with plenty of free margin left.

Now suppose EUR/USD drops 100 pips. On one standard lot that is a loss of about $1,000, or roughly €910. Under the 400:1 set-up, nearly half the account has gone on a 0.9% move in a major currency pair, which can happen in a single session around a central bank decision. Under the 30:1 cap, you were forced to trade a smaller size to begin with, so the same move costs less. This is the whole argument for the caps: they make it physically harder to take a position that a normal market move can destroy. For the sizing maths you should be doing anyway, see position sizing.

The 50% margin close-out rule

Brokers have always had a stop-out level, the point at which they start closing your positions automatically. Before 2018 these varied widely, and some offshore firms set them at 20% or lower. ESMA standardised it for retail clients: once the equity in your account falls to 50% of the margin required to keep your positions open, the broker must close one or more positions.

Worked example, illustrative numbers. You have €3,000 in the account and open a position that requires €2,000 of margin. Your margin level is equity divided by used margin, so 3,000 / 2,000 = 150%. The trade moves against you and your equity falls:

• At €2,000 equity, the margin level is 100%. You have no free margin and cannot open new trades. Many brokers issue a margin call warning around here.
• At €1,000 equity, the margin level is 50%. The broker must start closing positions, usually the largest losing one first.

You have lost €2,000 of €3,000 before the close-out, so the rule does not stop you losing a lot. What it does is make sure there is still a buffer when positions are closed, so that a fast-moving market is less likely to push the account below zero before the close-out completes. Our guide to margin calls and stop-outs walks through margin level calculations in more detail.

Two practical points follow. First, the close-out level is not a risk management plan. If your only protection is the broker's 50% rule, you are letting the market choose your exit at the worst possible moment. Use a stop-loss you have chosen; see where to put a stop-loss. Second, because the rule applies per account, holding several positions means one losing trade can trigger closures of others. Brokers' close-out orders and logic vary, so read your firm's order execution policy.

Negative balance protection

Before 2018 it was entirely possible to end a bad day owing your broker money. The most famous case was the Swiss National Bank's removal of the EUR/CHF floor on 15 January 2015, when the franc surged against the euro within minutes and price feeds gapped straight past stop-losses. Some retail clients were left with negative balances many times larger than their deposits, and several brokers either chased those debts or failed themselves.

Negative balance protection means that, for a retail client, the maximum loss is the money in the CFD account. If a gap pushes your equity below zero, the broker has to absorb the shortfall and reset the balance to zero. You cannot be pursued for the difference.

A few details are worth knowing:

• It applies per account, not per trade. Losses on several open positions are added together, and the floor is the account balance as a whole. If you hold more than one account with a broker, read the terms on how they are treated.
• It does not protect you from losing everything you deposited. It protects you from losing more than that.
• It does not cover slippage within your balance. If your stop is hit 40 pips beyond its level because of a gap, you bear that loss; NBP only kicks in below zero. Our guide to slippage covers why gaps happen.

The incentives ban

Under the ESMA rules a broker cannot offer retail clients monetary or non-monetary benefits linked to trading CFDs. That rules out deposit matches, trading credits, cashback for volume and gifts for opening an account. Information and research tools are allowed as long as they relate to the product.

The reasoning is simple. An incentive tied to deposits or volume encourages people to put in more money and trade more often, which is the opposite of what a beginner needs. If a firm claiming EU regulation is advertising a deposit match, that is a reason to check the firm's licence on the regulator's register, because a properly authorised EU entity should not be offering it to retail clients.

The standardised risk warning

The last protection is the one you have seen most often. Every EU and UK CFD provider has to display a warning that states the percentage of its own retail accounts that lost money over a recent period (in the EU, broadly the last 12 months, updated quarterly). The wording is set out in the measures. It typically reads along the lines of: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage, and a given percentage of retail investor accounts lose money when trading CFDs with this provider.

Brokers' published figures generally range from the low 60s to the high 80s as a percentage. The number is useful because it is firm-specific and comes from the firm's own data, but it is a blunt measure: it counts accounts, not money, and does not tell you how much was lost. We look at what the figures do and do not show in our guide on why most retail CFD traders lose, and our full risk warning page explains the position this site takes.

Did the rules work?

The evidence suggests the measures reduced harm without solving the underlying problem. The most detailed published data comes from Australia, where ASIC introduced a near-identical order in March 2021. In its October 2026 consultation on extending the order, ASIC reported that within six months of the original order, aggregate net losses on retail client accounts fell 91%, from A$372 million to A$33 million a quarter, and margin close-outs fell 87%. It also noted that retail losses over its most recent 12-month data period still exceeded A$458 million, including A$73 million in fees, and that most retail investors still lose money.

That pattern matches what you would expect. Lower leverage means fewer accounts are wiped out by a single bad move, so aggregate losses fall sharply. But leverage was never the only reason people lose. Costs, poor sizing, no edge and behaviour all remain, which is why the loss disclosures are still high years later.

Rules in other regions

The ESMA model has been widely copied, but not everywhere.

• United Kingdom. The FCA applies the same leverage caps, 50% close-out, negative balance protection, incentives ban and risk warning to retail CFD and spread betting clients. The FCA's own earlier work had found that 82% of sampled client accounts lost money in its 2016 proposals.
• Australia. ASIC's CFD product intervention order took effect on 29 March 2021 with the same leverage ratios as ESMA, a 50% close-out and negative balance protection. It was extended in 2022 and is currently due to expire on 23 May 2027. In October 2026 ASIC consulted on extending it for a further ten years, to 2037, subject to ministerial approval; at the time of writing that extension is a proposal, not a final decision.
• United States. Retail CFDs are not permitted. Retail spot forex is regulated by the CFTC and NFA, with leverage limited to 50:1 on major currency pairs and 20:1 on others. There is no ESMA-style negative balance protection, and US retail traders cannot use most offshore brokers legally.
• Japan. Retail forex leverage has been capped at 25:1 for individuals for over a decade.
• Offshore jurisdictions. Many brokers with EU or UK entities also run sister companies regulated in places such as St Vincent and the Grenadines, Vanuatu, Seychelles or Mauritius, where leverage of 500:1 or more is still offered. The protections described in this guide do not apply there, and the quality of oversight varies enormously. See our list of regulator registers for checking who actually licenses a firm.

The onboarding switch to watch for

A common pattern: you sign up on a broker's global website, and the account is opened with the offshore entity by default, sometimes with a box to tick confirming you approached the firm on your own initiative. If you live in the EU or UK, read which legal entity your contract is with. It is printed in the client agreement and usually in the website footer. The licence on your contract is the only one that matters. Our guide to choosing a forex broker has a short checklist.

Professional client status

MiFID II allows a retail client to ask to be treated as an elective professional client. The ESMA restrictions apply only to retail clients, so professional clients can be offered higher leverage (often 100:1 to 500:1 on forex) and are not covered by the mandatory 50% close-out, the incentives ban or the mandatory negative balance protection. Some brokers offer negative balance protection to professional clients voluntarily, but that is a commercial choice and can be withdrawn.

To be treated as professional you must meet at least two of three criteria set out in MiFID II:

1. You have carried out transactions of significant size on the relevant market at an average frequency of 10 per quarter over the previous four quarters.
2. Your financial instrument portfolio, including cash deposits, exceeds €500,000.
3. You work, or have worked, in the financial sector for at least one year in a professional position that requires knowledge of the transactions envisaged.

The broker has to assess your expertise, experience and knowledge, warn you in writing of the protections you will lose, and get your written confirmation. A firm that waves people through with a checkbox is not doing its job.

Should you opt up?

For almost every retail trader the honest answer is no. The thing professional status gives you is more leverage, and lack of leverage is not why most people lose. If you have a genuinely large portfolio and real trading frequency, higher leverage can make margin usage more efficient, but you give up the safety net at the same time. Be particularly wary of any firm that suggests you upgrade, offers help to qualify, or makes higher leverage the main selling point. Those are features of firms that make their money from client losses, a conflict we explain in how forex brokers make money.

Common mistakes and misunderstandings

• Thinking 30:1 is a recommended level. It is the legal maximum for retail clients. Most experienced traders use far less effective leverage on their accounts as a whole, often in single digits.
• Treating the 50% close-out as a stop-loss. It is an emergency brake, not a plan. By the time it fires you have usually lost more than you would ever accept on a planned trade.
• Assuming negative balance protection covers everything. It stops your balance going below zero. It does not refund losses within your balance, slippage, or swap charges. For overnight costs see swap and overnight financing.
• Moving offshore for leverage. You give up the protections in this guide, and often investor compensation schemes and ombudsman routes too, to get the one thing that most reliably accelerates losses.
• Not checking which entity holds your account. Same brand, same platform, entirely different protections.

Frequently asked questions

What is the maximum leverage for retail forex traders in the EU?

The maximum is 30:1 on major currency pairs (pairs made of USD, EUR, JPY, GBP, CAD and CHF) and 20:1 on all other currency pairs. Gold and major indices are also capped at 20:1, other commodities and minor indices at 10:1, individual shares at 5:1 and cryptocurrencies at 2:1.

Does negative balance protection mean I cannot lose money?

No. It means you cannot lose more than the money in your CFD account. You can still lose all of it, and most retail CFD accounts lose money over time. Negative balance protection only matters in extreme events, such as a price gap that skips past your stop-loss and the broker's close-out level.

Are the UK rules the same as the EU rules after Brexit?

For retail CFD clients they are effectively the same. The FCA made its own permanent rules in 2019, matching ESMA's leverage limits, 50% close-out, negative balance protection, incentives ban and risk warning, and they also cover spread betting. Details such as how the risk warning percentage is calculated differ slightly.

Why does my broker offer 500:1 if ESMA limits leverage?

Usually because your account is held with a separate, non-EU entity of the same brand, or because you have been classified as a professional client. Check the legal entity named in your client agreement and look it up on the relevant regulator's register. If it is offshore, the ESMA protections do not apply to you.

How do I qualify as a professional client?

You need to meet two of three MiFID II criteria: around 10 significant trades per quarter over the past year, a portfolio including cash above €500,000, or at least a year working in a relevant financial role. The broker must assess you, warn you in writing about lost protections and get your written agreement.

Do the rules apply to spot forex or only to CFDs?

In the EU and UK, retail forex is almost always offered as a CFD or rolling spot contract, which falls within the measures. Physically settled currency exchange, such as converting money for a holiday or a business payment, is not covered. For the distinction, see our guide on what a CFD is.
