What is MiFID II?
MiFID II (Markets in Financial Instruments Directive II) is the EU regulatory framework governing investment firms and financial instruments, in force since 2018. While retail prop firms typically operate outside MiFID II scope by using simulated accounts, the framework's transparency and best-execution requirements influence how prop firms partner with regulated brokers. As of 2026, several major prop firms have restructured EU operations to ensure their broker partners are MiFID II compliant.
