What you'll learn
- Define leverage and read a ratio
- See how it multiplies gains and losses
- Know the leverage caps regulators impose
The mechanism
The broker asks you to deposit a fraction of the position's value as margin and lends the rest in effect, though no money changes hands. At 1:30 the fraction is one thirtieth, about 3.3 percent. At 1:100 it is 1 percent. At 1:500 it is 0.2 percent. The position's value is what moves with the market, so a 1 percent move on a 30,000-dollar position is 300 dollars, which is 30 percent of a 1,000-dollar deposit.
What leverage changes and does not
Leverage does not change how far the market moves or how likely you are to be right. It changes how much of your account each pip is worth. Two traders with identical entries and stops, one using a 10,000-dollar position and one a 100,000-dollar position, have the same win rate and ten times the difference in outcome. That is why leverage on its own is neither good nor bad; the position size it produces is what matters, and the lesson on position sizing shows how to choose it.
Regulatory caps for retail clients
| Regulator | Major pairs | Other |
|---|---|---|
| FCA, ESMA regulators, ASIC | 1:30 | 1:20 minors and gold, 1:10 commodities, 1:5 shares, 1:2 crypto |
| US (CFTC/NFA) | 1:50 | 1:20 minors |
| Japan | 1:25 | 1:25 |
| Singapore | 1:20 | 1:20 |
| Offshore regulators | Often 1:500 to 1:2000 | Varies |
Why the caps exist
Regulators studied retail account outcomes and found that higher leverage correlated with faster and larger losses. Capping leverage at 1:30 does not stop anyone losing, but it slows the rate, because the largest position a 1,000-dollar account can open is 30,000 dollars rather than a million. A broker offering 1:500 is offering a faster way to lose the same money, which some experienced traders want and no beginner needs.
Example: The same trade at two leverages
Account: 2,000 dollars. Trade: buy EUR/USD, 50-pip stop. At 1:30 the largest position is 60,000 dollars, 0.6 lots, on which 50 pips is 300 dollars, or 15 percent of the account. At 1:500 the largest position is a million, 10 lots, on which 50 pips is 5,000 dollars, more than the account. Neither is a sensible size; the point is that the account and the stop were identical and leverage set the range of possible mistakes.
Key takeaways
- Leverage controls a position many times your deposit; profit and loss are on the full position.
- It multiplies outcomes without changing the odds.
- Retail caps are 1:30 in the UK, EU and Australia, 1:50 in the US, and far higher offshore.
- Position size, not leverage, is the number to manage.
