Overseas FX Leverage Regulation: How It Differs From Japan's 25x Limit, and Maximums by Broker
Wondering why overseas FX offers 1000x or 2000x leverage when domestic FX in Japan stops at 25x?
The Financial Services Agency of Japan explains that individuals trading over-the-counter FX in Japan must post margin of at least 4% of the trade amount. That works out to leverage of 25x or less. Overseas brokers' limits vary by regulator, account type, balance and more.
This article lets you check how it differs from the domestic rule and the maximum leverage at supported brokers. It also covers cautions about high leverage.
In short: 25x at most in Japan, while overseas limits vary by broker and conditions

What Japan's domestic FX leverage regulation (25x) says
The Financial Services Agency of Japan explains that when individuals trade over-the-counter FX, they must post and maintain margin of at least 4% of the trade amount, regardless of the currency pair.
Converted to leverage, that is 25x or less. The FSA published this margin rule in 2009 as a proposed amendment to the Cabinet Office Ordinance on Financial Instruments Business.

Cautions on high leverage (stop-out and margin)
- On USDJPY, 1 lot (100,000 units) moves about ¥100,000 in profit or loss for every ¥1 the price moves
- Even if required margin is small, your margin level falls as unrealized losses grow
- Stop-out levels differ by broker (Exness is 0%, HFM is 20% and KATANA is 0%)
- Around economic releases and weekend gaps, execution can slip and stop-outs can be delayed
What matters more than a high multiple is choosing a lot size that suits your funds. For how losses work, also see the zero-cut article.
How leverage relates to cashback
