Financial Industry Regulatory Authority (FINRA)
The Financial Industry Regulatory Authority (FINRA) is a self-regulatory organization (SRO) that oversees U.S. broker-dealers and securities firms. While it’s not a government agency, it operates under the supervision of the Securities and Exchange Commission (SEC) and plays a central role in maintaining fairness and transparency across financial markets. FINRA's mission is to protect investors by ensuring that the broker-dealer industry operates honestly and ethically.
