SROs ensure that their members comply with federal securities laws and regulations, but they are not government entities.
FINRA is a non-governmental organization that regulates broker-dealers and other members of the securities industry.
FINRA ensures that broker-dealers adhere to rules designed to protect investors and maintain fair markets.
SROs do not control monetary policy; that is the role of central banks, such as the Federal Reserve.
While SROs have regulatory authority, the SEC provides oversight to ensure that SRO rules are consistent with federal securities laws.
