The EU caps retail leverage on major pairs at 1:30 and the US at 1:50. For anyone who sizes trades from the stop, the setting moves the margin and leaves the loss alone.
- Margin is the position’s value divided by leverage. On 8 October 2026 one lot of EURUSD was worth $111,860, so 1:50 locked $2,237 and 1:100 locked $1,119.
- The loss at a stop depends on lot size, stop distance and pip value. One lot of EURUSD pays $10 a pip on a USD account at any setting.
- ESMA’s 2018 limits, now kept in national rules: 30:1 on major pairs, 20:1 on other pairs and gold, a close-out at 50% of required margin, negative balance protection.
- In the US, CFTC rule 17 CFR 5.9 sets a minimum deposit of 2% on major pairs and 5% on the rest, which works out to 50:1 and 20:1.
On 8 October 2026 one standard lot of EURUSD tied up $3,729 of margin at 1:30 and $224 at 1:500, and a 40-pip stop on it cost $400 at both. Forex leverage is the ratio between the size of your position and the margin the broker holds for it: at 1:30 you put up 3.33% of the position’s value, at 1:500 you put up 0.2%, and the pip value and the loss at your stop are set by lot size and stop, not by leverage. You’re filling in the account form, the leverage box offers 1:30 to 1:500, and your cursor hovers as if it decided how much the next trade can hurt.
On a trade you sized from the stop, it doesn’t. The broker sets aside a smaller deposit, the free margin figure gets bigger, and nothing else on the order ticket moves.
Yet ESMA cut retail leverage on major pairs to 30:1 in 2018, after national regulators found that 74% to 89% of retail CFD accounts lose money. If the loss at the stop is the same at 1:30 and 1:500, what exactly does the cap take away?
Which leverage is better, 1:30 or 1:100?
For a trader who risks a fixed share of the balance per trade, neither: both give the same position, the same pip value and the same loss at the stop. Only the margin locked while the trade is open differs.
We took the ECB reference rates for 8 October 2026 (EURUSD 1.1186, GBPUSD 1.3207, USDJPY 158.28 worked out from them) and divided one lot’s value by each ratio:
- EURUSD: $3,729 at 1:30, $2,237 at 1:50, $1,119 at 1:100, $224 at 1:500. Loss at a 40-pip stop: $400.
- GBPUSD: $4,402, $2,641, $1,321 and $264. Loss at a 40-pip stop: $400.
- USDJPY: $3,333, $2,000, $1,000 and $200, because the position is counted in dollars from the start. Loss at a 40-pip stop: $252.72.
Across each line the deposit falls almost 17 times from 1:30 to 1:500 and the stop doesn’t move a cent. The yen stop is cheaper because one pip on one lot of USDJPY is 1,000 yen, which at 158 yen to the dollar is $6.32, not $10.
When you last changed your ratio, were you watching the margin line or the stop line?
How to calculate margin in forex
Multiply lots by contract size and price, divide by leverage, convert to your account currency. For one lot of EURUSD on a USD account at 1:30 that’s 1 × 100,000 × 1.1186 ÷ 30 = $3,729.
The loss at a stop has its own formula, with no ratio in it:
So a forex margin calculator tells you whether the platform will accept the order, and a position size calculator tells you what the order costs if the stop is hit. Our lot size calculator does the second: balance, risk and stop in, position size out. Put that size into the margin formula above and you have the deposit too.
Three accounts, each risking 1% on a 40-pip EURUSD stop:
| Account | Size at 1% risk | Loss at 40 pips | Margin at 1:30 | Margin at 1:500 | Largest size at 1:30 | Largest size at 1:500 |
|---|---|---|---|---|---|---|
| $2,000 | 0.05 | $20 | $186 | $11 | 0.54 | 8.94 |
| $10,000 | 0.25 | $100 | $932 | $56 | 2.68 | 44.70 |
| $50,000 | 1.25 | $500 | $4,661 | $280 | 13.41 | 223.49 |

Take the $10,000 row. The planned trade loses $100 at 40 pips under any setting; only the last two columns change. At 1:30 the biggest position the platform will open is 2.68 lots, and 40 pips against it costs $1,073, or 10.7% of the balance. At 1:500 the ceiling is 44.70 lots: on paper 40 pips against it costs $17,879, or 178.8% of the balance; in practice the account is gone after 22.4 pips, and the 50% close-out fires after about 11. The cap leaves the trade you planned alone and shrinks the largest trade you can open in a hurry from 44.70 lots to 2.68.
Have you fixed a “not enough money” message by raising the ratio instead of cutting the lot? On the $2,000 row it comes at 0.54 lots on 1:30, and on 1:500 not until 8.94.
What leverage should I use in forex?
We’d take the lowest leverage on which your normal trade opens with room to spare, and on EURUSD with any stop wider than a few pips that is 1:30. A 1% risk with a 40-pip stop locks 9.3% of the balance as margin at 1:30, whatever the balance: $186 of $2,000, $932 of $10,000.
The limit only bites on very tight stops: a 1% trade would need the whole balance as collateral at 1:30 with a stop under 3.73 pips, at 1:50 under 2.24. Above that, extra gearing is room only a slipped finger on the volume box will use.
The case for more leverage is about free margin. On $10,000 the 0.25-lot trade leaves $876 more of it at 1:500 than at 1:30, which matters if you hold several positions at once. The $100 at the stop stays exactly where it was.
Where the margin number misleads you:
- It isn’t fixed in dollars. At the same 1:30, one lot of EURUSD needed $4,961 on 4 May 2011, at an ECB rate of 1.4882, and $3,188 on 28 September 2022, at 0.9565. On the chart four margin lines drift with the euro while the $400 stop stays flat. At 1:500 it never topped $298 since 2010, less than one stopped-out trade.
- The stop belongs to the pair. USDJPY at 1:30 needs $3,333 against $3,729 on EURUSD, and its 40-pip stop is $252.72 against $400.
- The broker has its own stop. ESMA’s close-out sits at 50% of the required deposit: on $10,000 with one lot at 1:30, $1,864 of equity, about 814 pips away.
- A stop can be jumped. ESMA’s FAQ points to January 2015, when the euro fell suddenly against the Swiss franc and some retail clients without negative balance protection ended up owing their providers very large sums, often much more than they could afford. The bigger the position, the further past zero a gap goes.
What is the maximum forex leverage in the EU and US?
In the EU it’s 30:1 on major pairs for retail CFD clients and 20:1 on other pairs, gold and major indices. ESMA’s major pairs combine any two of the dollar, euro, yen, pound, Canadian dollar and Swiss franc. The measures, listed in the ESMA press release of 27 March 2018, applied from 1 August 2018. ESMA let them expire on 31 July 2019 because most national regulators had made permanent rules at least as strict.
“The new measures on CFDs will for the first time ensure that investors cannot lose more money than they put in, restrict the use of leverage and incentives, and provide a risk warning for investors.”
Steven Maijoor, then ESMA Chair, ESMA press release, 27 March 2018
in the US the floor is written as a deposit, not a ratio. CFTC rule 17 CFR 5.9 requires at least 2% of the notional value on major pairs and 5% on all others, which is 50:1 and 20:1. NFA sets the actual rate; its guide gives EUR/USD at 2% and notes changes to the minimums in January 2015, November 2016 and September 2018. Source: eCFR, 17 CFR 5.9, and NFA Forex Transactions Regulatory Guide, checked October 2026.
What we couldn’t find is how close retail traders trade to these ceilings: ESMA’s 2018 papers give loss rates, not position sizes.
What is leverage in forex?
Leverage in forex is borrowed exposure: at 1:30 each dollar of collateral controls $30 of currency, at 1:500 it controls $500. Margin is a deposit held while the trade is open, not a fee, and it comes back when you close.
Free margin is the equity left after that deposit; it shrinks as you add trades or a trade goes against you.
Back to the account form. Whatever you pick in the ratio box, the 0.25-lot trade on $10,000 still loses $100 at 40 pips; the box only decides whether the platform would also open 44.70 lots, a position that empties the account in 22.4 pips.
