See it on the Money & Finance map →How it works
FINRA formed in 2007 when the National Association of Securities Dealers (founded 1939) merged with the New York Stock Exchange's regulation arm. Any firm selling securities to the public must join. It oversees about 3,300 firms and more than 600,000 registered brokers, writes conduct rules, gives licensing exams such as the Series 7, examines firms, fines violators and runs an arbitration forum for customer disputes. Funded by member fees, it also watches trading across exchanges for manipulation and insider trading.
Why it matters
It is the front-line cop for the brokers individual investors actually deal with; its free BrokerCheck tool shows any broker's licenses, complaints and discipline.
Facts, rules and data
FINRA annual financial reports and its disciplinary actions database; SEC orders approving its rules; BrokerCheck records at brokercheck.finra.org.
Debates and risks
Whether a private body can constitutionally discipline firms without direct government control is being fought in court, including a 2024 appeals ruling in Alpine Securities v. FINRA.

▸Securities and Exchange Commission (SEC) oversees FINRA: the brokers' self-regulatorFact, law or data
The connection
FINRA writes rules for brokers, but each needs SEC approval. The SEC inspects FINRA, hears appeals of its disciplinary decisions and can override it. The arrangement lets the industry fund and staff its own front-line supervision while government keeps final control.
When and why
The model began with the 1938 Maloney Act, which led to the NASD in 1939; FINRA has operated under SEC oversight since its 2007 creation.
How we know
Sections 15A and 19 of the Exchange Act; SEC orders approving FINRA rule changes; SEC decisions on appeals of FINRA discipline.
Debates and risks
Critics say a private body wielding government-like power is unconstitutional; a 2024 appeals ruling barred FINRA from expelling a firm before SEC review.
▸FINRA: the brokers' self-regulator surveils markets for Insider tradingFact, law or data
The connection
FINRA's surveillance systems scan billions of trading records a day across US stock and options markets, flagging unusual buying just before mergers or earnings news. Analysts then pull account details from brokers to see who traded and any links to insiders. Because FINRA cannot charge people outside its member firms, it refers suspects to the SEC.
When and why
Nationwide, run from FINRA's market-surveillance offices; it refers hundreds of possible fraud and insider-trading matters to the SEC each year.
How we know
FINRA's annual reports on referrals; SEC insider-trading complaints that credit FINRA surveillance; the Consolidated Audit Trail, a database of nearly every US stock and options order.
Debates and risks
Surveillance catches suspicious timing, not the tip itself; tips passed through friends or encrypted apps are hard to prove, and the audit trail's cost and privacy draw lawsuits.
▸FINRA: the brokers' self-regulator licenses and polices the firms behind Brokerage accounts and SIPC protection (up to $500,000)Fact, law or data
The connection
FINRA, a private regulator overseen by the SEC, licenses brokers, examines firms and enforces rules, including the capital and customer-asset rules that keep client accounts whole. When it spots a member firm in financial trouble it must alert SIPC, which can step in to liquidate the firm and return customer assets.
When and why
Formed in July 2007 by merging the NASD with NYSE member regulation; it oversees about 3,300 brokerage firms.
How we know
The Securities Investor Protection Act requires such notice; FINRA's BrokerCheck lists every registered broker and firm.
Debates and risks
Whether industry self-regulation works: FINRA and its predecessor examined Madoff's brokerage but missed the fraud run alongside it.
▸Dark pools and off-exchange trading (about half of US volume) report their trades to FINRA: the brokers' self-regulatorFact, law or data
The connection
Dark pools are run by broker-dealers, so FINRA, the brokers' self-regulator, oversees them. Their trades must be reported to FINRA's trade reporting facilities, generally within 10 seconds, and FINRA publishes each pool's weekly volume after a short delay. FINRA and the SEC have fined pools for misleading clients.
When and why
Nationwide; FINRA's weekly dark-pool volume reports began in 2014.
How we know
FINRA rules and its OTC Transparency data, plus 2016 enforcement cases against Barclays and Credit Suisse.
Debates and risks
Whether delayed reporting gives enough transparency to judge dark pools' effect on prices.
