Europe's CFD rules, explained: leverage caps, margin close-out and the risk warning
Since 2018, every EU broker selling CFDs to retail clients has worked within the same five rules. Here is what each one does, with a worked example of the margin close-out.
Retail CFD accounts losing money in regulators' 2018 analyses
74% to 89%
Core protections for retail clients
5
Contracts for difference let a client take a leveraged position on the price of an asset without owning it. In 2018 Europe’s securities regulators concluded that, sold to retail investors, they posed “a significant investor protection concern.” The rules that followed still define how every EU CFD provider operates.
Where the rules came from
ESMA’s Board of Supervisors agreed the measures on 23 March 2018. The evidence behind them was stark: national regulators’ analyses “across different EU jurisdictions” showed “that 74-89% of retail accounts typically lose money on their investments, with average losses per client ranging from €1,600 to €29,000.”
ESMA adopted the measures as a temporary decision (Decision (EU) 2018/796 of 22 May 2018) and renewed it quarterly until 31 July 2019. In the meantime every national regulator adopted permanent measures that, in ESMA’s words, mostly mirrored the ESMA decision “without any changes.” In the UK, the FCA made its own permanent rules, which firms had to follow from 1 August 2019 for CFDs.
Rule one: leverage limits
Leverage on opening a position is capped according to how volatile the underlying is:
Underlying
Maximum leverage
Minimum margin
Major currency pairs
30:1
3.33%
Non-major currency pairs, gold, major indices
20:1
5%
Commodities other than gold, non-major equity indices
10:1
10%
Individual equities and other reference values
5:1
20%
Cryptocurrencies
2:1
50%
Maximum retail leverage by underlying (x:1)
Item
Value
Major FX pairs
30:1
Non-major FX, gold, major indices
20:1
Other commodities, non-major indices
10:1
Individual equities
5:1
Cryptocurrencies
2:1

Rule two: margin close-out
Providers must close out a retail client’s positions when the funds in the account fall to 50% of the margin required to keep them open. The rule works per account, across all of the client’s open CFDs.
A worked example. A client opens a €30,000 position on EUR/USD. At 30:1, the required margin is €1,000. If losses reduce the account’s equity to €500, which is 50% of the required margin, the provider must close one or more positions. The client keeps what is left rather than losing the whole deposit.
Rule three: negative balance protection
Losses are capped at the money in the account. ESMA’s chair described the effect when the measures were announced: the rules “ensure that investors cannot lose more money than they put in.” A sudden gap in prices can no longer leave a retail client owing the broker money.
Rule four: no incentives
Providers may not offer monetary or non-monetary benefits, such as trading bonuses, to encourage retail clients to trade CFDs.
Rule five: the risk warning
Every provider must show a standardised risk warning, including the percentage of its own retail accounts that lose money. It is the line visible at the foot of every EU broker’s website: “CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage,” followed by the firm’s percentage.
Because the percentage is firm-specific, it is one of the few performance figures that can be compared directly across brokers.
Who is protected
The measures apply to retail clients. A client who is reclassified as a professional client loses these protections, including the leverage caps and negative balance protection, which is why regulators scrutinise how firms handle requests to be treated as professional.
Still current
The rules are not historical. In February 2026 ESMA reminded firms that derivatives marketed as “perpetual futures” are likely to fall within these same measures. We cover that statement here.
A February 2026 statement tells firms that the commercial name of a leveraged derivative is irrelevant. What matters is whether it meets the definition of a CFD, and most perpetuals likely do.
