I understand that in the United States, the maximum leverage allowed for forex trading is regulated by the Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA). For major currency pairs, the maximum leverage is set at 50:1. For non-major currency pairs, the maximum leverage is lower, set at 20:1.
These leverage limits are stricter than those in many other countries, such as Europe, where the maximum leverage for major currency pairs is typically 30:1, or Australia, where it can be as high as 500:1.
The question is:
Is there a way US citizens can access leverage of 500:1 for forex trading through non-US-based brokers with all these regulations imposed by the Commodity Futures Trading Commission (CFTC) and the National Futures Association?
This is not a direct answer to your request , but a possible work-around if you are a day trader. Overnight margin on CME currency Futures is set at 50:1, but brokers have at their discretion can offer much higher day trading margin, frequently up to the 500:1 you are looking for.
