FINRA vs SEC: How the Two Regulators Divide Oversight

The SEC (Securities and Exchange Commission) is a federal agency with broad authority over the securities industry, while FINRA (Financial Industry Regulatory Authority) is a self-regulatory organization that oversees broker-dealers and certain conduct rules. The two work in parallel: the SEC sets broad policy and standards, and FINRA enforces detailed rules against its members. Their jurisdictions overlap, creating a layered regulatory structure.

The SEC’s Mandate and Authority

The SEC was created in 1934 during the Great Depression, mandated to protect investors, ensure fair and efficient markets, and facilitate capital formation. The agency is headquartered in Washington, D.C., and operates under the Securities Act of 1933 and the Securities Exchange Act of 1934, among other statutes.

The SEC’s broad role includes:

• Regulating securities exchanges and the securities industry.
• Enforcing federal securities laws (insider trading, fraud, market manipulation).
• Reviewing and enforcing disclosure requirements for public companies.
• Overseeing investment companies, including mutual funds and ETFs.
• Regulating investment advisers.
• Setting accounting standards (via the Financial Accounting Standards Advisory Board).

The SEC is a government agency with statutory power. When the SEC brings an enforcement action, it acts through the federal legal system. The agency can issue subpoenas, levy fines, and bring civil or criminal referrals. The SEC’s decisions can be appealed to federal court.

FINRA’s Mandate and Structure

FINRA emerged in 2007 from a merger of the National Association of Securities Dealers (NASD) and the New York Stock Exchange’s regulatory arm. It operates as a self-regulatory organization (SRO)—a private organization delegated regulatory authority by the SEC.

FINRA oversees its members, which are primarily:

• Broker-dealers: Firms that buy and sell securities and execute trades for clients.
• Brokers: Individual securities professionals registered through FINRA.

FINRA membership is not optional for firms engaging in broker-dealer activities. Registration as a broker-dealer automatically triggers FINRA regulation. FINRA is not a government agency but a quasi-governmental private entity with significant statutory and delegated power.

How Their Jurisdictions Differ

Investment advisers: The SEC directly regulates registered investment advisers (RIAs), firms that manage portfolios and provide advice for a fee. FINRA does not regulate RIAs unless they are also registered as broker-dealers. If an RIA also engages in brokerage (e.g., executes trades for clients), it may be subject to FINRA rules as a broker-dealer member. This creates a dual-registered category: firms that are both SEC-regulated advisers and FINRA-regulated broker-dealers.

Broker-dealers: These are FINRA members by necessity. FINRA sets and enforces rules governing their conduct, sales practices, capital requirements, and employee certifications. The SEC also regulates broker-dealers through the Securities Exchange Act and related rules, but FINRA is the primary day-to-day regulator for conduct and compliance.

Securities exchanges: The SEC directly oversees exchanges like the New York Stock Exchange (NYSE) and the NASDAQ. Exchanges are also SROs but are not part of FINRA. Each exchange has its own regulatory arm that oversees listed companies and trading conduct on that exchange.

Markets and trading: The SEC oversees market structure, including circuit breakers, short-selling rules, and market-manipulation enforcement. FINRA enforces conduct rules against its member firms in trading and sales.

Overlapping Jurisdiction: The Suitability and Fiduciary Standards

A key area of overlap concerns suitability and fiduciary duty. FINRA members (broker-dealers and brokers) are subject to FINRA’s suitability rule: recommendations must be suitable for the customer based on their financial situation and needs. FINRA enforces this rule and brings disciplinary actions against members who violate it.

The SEC regulates investment advisers under the Investment Advisers Act of 1940, which imposes a fiduciary duty: advisers must act in clients’ best interests, not their own. The fiduciary standard is higher than suitability.

When a broker-dealer provides investment advice in its advisory capacity, the SEC may assert that it is acting as an investment adviser and should meet the fiduciary standard. When a dual-registered firm (both broker-dealer and adviser) conducts business, both the FINRA suitability rule and the SEC fiduciary standard may apply, depending on which hat the firm is wearing. This ambiguity has led to regulatory and court disputes.

Enforcement and Disciplinary Processes

FINRA enforcement: FINRA runs its own disciplinary system. Investigations are conducted by FINRA staff. Hearings are held before a FINRA adjudicator or panel. Decisions can be appealed within FINRA. Members can appeal a final FINRA decision to the SEC, which can review it. A member can also bring a case to court challenging the FINRA action.

SEC enforcement: The SEC brings civil and criminal actions through the Department of Justice. Cases proceed through the federal legal system. Fines can be substantial, and criminal referrals can result in prison time for individuals.

Coordination: The SEC and FINRA coordinate on major cases. If FINRA uncovers fraud or a violation of federal securities law, it may refer the matter to the SEC or to law enforcement. Conversely, the SEC may refer conduct matters to FINRA for disciplinary action. The two agencies do not have a conflict; they operate in parallel.

Registration and Licensing

All brokers and broker-dealer employees in the United States must pass FINRA exams (such as the Series 7 general securities exam or the Series 65 investment adviser exam) and register through FINRA’s Central Registration Depository (CRD). This is not optional; it is the gateway to working in brokerage.

Investment advisers register with the SEC (if they have more than $110 million in assets under management, or AUM) or with state securities regulators (if below that threshold). They are not required to register with FINRA.

The Dodd-Frank Act and Expanded Authority

The Dodd-Frank Act of 2010 expanded SEC authority over the financial industry. It created new rules governing derivatives, hedge funds, and mortgage-backed securities. Dodd-Frank also gave the SEC and FINRA new authority to regulate certain aspects of the financial system, such as money-market funds and systemic risk.

Dodd-Frank also formalized the distinction between investment advisers and broker-dealers by defining an “adviser” as someone providing advice for a fee and a “broker” as someone executing trades. The act required the SEC and FINRA to align their standards, but the fiduciary-vs.-suitability divide remains.

Criticisms and Debates

Over-regulation: Some argue that the two-regulator system is redundant and creates compliance burdens. A firm must navigate both SEC and FINRA rules, filing requirements, and examination procedures. The cost falls on institutions and is passed on to retail investors.

Under-enforcement: Others argue that the system is too lenient. FINRA, as a private organization funded by member fees, may have weak incentives to aggressively enforce against members. The SEC is under-resourced and cannot investigate all violations. Coordination between the two can be slow.

Conflicting standards: The suitability-vs.-fiduciary divide creates confusion about when each standard applies and what conduct is permissible. Regulators and courts have had to clarify the boundary through enforcement actions and litigation.

Evolving markets: New financial products (cryptocurrency exchanges, robo-advisers, decentralized finance) do not fit neatly into the broker-dealer/adviser categories. FINRA and the SEC have struggled to clarify whether new platforms are subject to their jurisdiction.
