Forex markets are regulated by various agencies around the world to ensure compliance and protect investors. In the United States, brokers are overseen by the National Futures Association (NFA) and the Commodities Futures Trade Commission (CFTC), rather than the Financial Industry Regulatory Authority (FINRA). In the United Kingdom, the Financial Conduct Authority (FCA) serves as the primary regulatory body for forex trading. In the European Union, each member state has its regulatory agency, but they are bound by the standards set forth in the Markets in Financial Instruments Directive (MiFID) to maintain consistency and uphold investor protections.
