Self-Regulatory Organisations and FINRA
Why much of the day-to-day policing of brokers and trading firms in the US is done not by a government agency but by an industry-funded body the government oversees — and what that arrangement is designed to achieve.
Prerequisites: Sell Side vs Buy Side
The SEC is the government agency with ultimate authority over US securities markets, but it doesn't directly supervise every broker's every trade — much of that hands-on work is delegated to self-regulatory organizations, industry bodies given legal authority to write and enforce rules for their own members, subject to SEC oversight. The idea is that an organization made up of industry participants has the expertise and reach to monitor day-to-day conduct more efficiently than a government agency could alone, while the SEC retains the power to approve or reject the SRO's rules and to step in directly when needed.
FINRA — the Financial Industry Regulatory Authority — is the largest SRO in US securities markets and the one most people encounter indirectly. Every broker-dealer and registered representative in the US must be a FINRA member, and FINRA is responsible for licensing brokers (the exams that produce those Series 7, Series 63, and similar qualifications), writing conduct rules for how brokers must treat customers, monitoring trading for manipulation and other misconduct, and running an arbitration system that resolves most disputes between investors and their brokers outside of court. It's funded by fees paid by its own member firms, not by taxpayers, which is part of what makes it "self"-regulatory rather than a government body.
The arrangement isn't unique to brokers — stock exchanges themselves also historically acted as SROs for their listed companies and members, though much of that day-to-day brokerage-conduct oversight has consolidated into FINRA over time. The practical value for anyone dealing with a broker is knowing where to complain: a dispute over how a broker handled an account or a suspicion of misconduct generally goes through FINRA's arbitration and enforcement processes first, not directly to the SEC, and FINRA maintains a public database (BrokerCheck) where anyone can look up a broker's or firm's disciplinary history before doing business with them.
A self-regulatory organization is an industry body granted legal authority to write and enforce rules for its own members, under SEC oversight rather than in place of it; FINRA is the main SRO for US broker-dealers, handling licensing, conduct rules, market surveillance, and investor dispute resolution, funded by member fees rather than taxpayer money.
Investors sometimes assume any securities dispute goes straight to a government regulator or a courtroom. In practice, most disputes with a broker are resolved through FINRA's arbitration process, which most brokerage account agreements require investors to use instead of suing in court — worth knowing before signing a new brokerage agreement, not after a dispute arises.
