Who sets the forex rate ? Is it the principal license holder or me as the business owner?

This guide explains the 2026 dynamics of FX control, how to negotiate tighter spreads with your principal, and why the 'Mid-Market Rate' is your most important benchmark for customer trust and margin protection.
