Leverage cap

Family VIII · Regulation

Not to be confused with leverage, forex leverage, leverage forex.

Leverage cap is a ceiling imposed by a financial regulator on the amount of leverage a firm may extend to retail clients. It is expressed as a ratio of notional exposure to required margin, so a 30:1 cap means a client must post at least one unit of margin for every thirty units of position value. Caps vary by regulator, instrument class and client categorisation, and they apply to the broker's offering rather than to any individual trade.^[1]

How a cap is applied

A cap is a maximum, not a target. A broker subject to a 30:1 cap on major currency pairs may offer less, and the cap does not prevent a client from holding a position larger than thirty times their deposit; it prevents the broker from accepting the order without sufficient margin. Margin requirements are therefore the operational form of the cap.

Caps are commonly tiered by asset class. Major FX pairs usually attract the highest permitted ratios, with lower caps for minor pairs, gold, major indices, individual equities and crypto. The same regulator may set different caps for different categories of client, with professional clients often exempt from retail limits.

Worked example

Margin required under a 30:1 cap

Position size1 standard lot of EUR/USD€100,000 notional

Leverage cap30:1Margin = notional ÷ 30

Required margin€100,000 ÷ 30€3,333.33

The same position under a 100:1 cap would require €1,000 of margin. The cap changes the margin requirement, not the profit or loss per pip on the position.

Where caps come from

Caps are set by statute or by regulator rulebook and are enforced through the broker's licensing conditions. Because they differ between jurisdictions, the same instrument may carry different margin requirements at two firms serving different regions. A firm may also apply its own lower house cap for risk management, which is a commercial decision rather than a regulatory one.

Regulatory caps bind the broker's retail offering in that jurisdiction.
House caps are internal limits and may be lower than the regulatory maximum.
Professional or elective professional classification can remove or raise retail caps where the regulator permits.
