What is the U.S. Securities and Exchange Commission?

The U.S. Securities and Exchange Commission (SEC) is an independent federal agency responsible for regulating the U.S. securities markets and protecting investors from fraud and market manipulation. It oversees exchanges, broker-dealers, investment advisers, and public companies to ensure fairness and transparency in the trading of securities. 

The SEC’s mission centers on three core aims: protect investors, maintain fair and orderly markets, and facilitate capital formation. These objectives guide rulemaking, examination programs, and enforcement actions that shape how participants behave in the U.S. financial system.

History and Founding of the SEC

The SEC was created in response to the stock market crash of 1929 and the ensuing Great Depression, which exposed widespread abuses in securities markets. In 1934, the U.S. Congress passed the Securities Exchange Act, formally establishing the SEC to restore public trust in financial markets. 

Its founding reflected a broader legislative effort that included the Securities Act of 1933, which required companies to provide truthful disclosures when offering securities to the public. Over time, the SEC’s authority expanded through additional statutes like the Investment Company Act of 1940 and Sarbanes-Oxley Act of 2002, strengthening investor protections and corporate accountability. 

How the SEC Fits into the U.S. Regulatory Landscape

As an independent agency, the SEC operates outside executive departments while remaining accountable to Congress. Commissioners are appointed by the President with Senate confirmation, and no more than three may belong to the same political party, which helps preserve non-partisan oversight. 

The SEC’s regulatory reach extends across a wide range of securities activities, including public offerings, market trading, disclosures, and financial reporting. It also works with self-regulatory organizations like FINRA to coordinate supervision and enforcement. 

The SEC’s Role in Compliance Today

While the SEC is best known for policing securities markets, it also plays a significant role in anti-money laundering (AML) and sanctions compliance for regulated entities such as broker-dealers and investment advisers. Through rulemaking and examinations, the SEC enforces requirements under the Bank Secrecy Act and related regulations that govern customer due diligence, suspicious activity reporting, and risk-based AML programs. 

Recent enforcement actions illustrate the SEC’s focus on AML controls, including cases where broker-dealers were charged for deficient suspicious activity reports or failures in AML policies. These actions highlight the regulator’s expectation that firms enforce robust AML compliance commensurate with their risk profiles.

In addition, emerging SEC emphasis includes oversight of investment advisers’ implementation of new AML program requirements, which take effect for many firms by January 2026. This underscores the agency’s evolving role in ensuring regulated entities meet anti-financial crime standards. 

Key Functions and Divisions of the SEC

The SEC’s structure supports its broad regulatory mandate through divisions focused on different parts of the market. The Division of Corporate Finance reviews disclosures by public companies to help ensure investors have access to accurate information. The Division of Enforcement investigates violations and brings civil actions or administrative proceedings against wrongdoers. Other divisions oversee trading markets, investment management, and economic analysis. 

Within enforcement, the SEC uses civil authority to pursue violators of federal securities laws and can seek monetary penalties, injunctions, and other remedies to protect investors and uphold market integrity. Enforcement actions may arise from investigations or complaints and, when appropriate, are litigated in federal court or handled through internal proceedings. 

Notable SEC Enforcement Examples

SEC regulatory activity often makes headlines and sets precedents that reinforce compliance expectations across the financial industry. For example, the agency has brought significant actions related to fraud and market misconduct in the crypto sector, including cases involving major digital asset platforms accused of unregistered offerings or misleading disclosures. 

High-profile historical cases like SEC v. Chenery Corp place the commission’s authority in context, showing how courts have upheld its power to enforce complex regulatory matters. Other landmark rules such as SEC Rule 10b-5 tackle insider trading and reinforce fair dealing obligations in securities markets.

These cases, among others, demonstrate that robust enforcement is integral to the SEC’s mission and reinforces compliance norms that benefit investors and market participants alike. 

Why the SEC Matters for Compliance Programs

The SEC’s actions and rulemaking shape the baseline expectations for compliance in the securities industry. Firms subject to its oversight must develop policies that detect fraud, prevent market abuse, and comply with AML and sanctions requirements. The agency’s public enforcement outcomes serve as reference points for what constitutes acceptable conduct and adequate controls.

Because the SEC’s standards influence how financial institutions operationalize risk management, its work strengthens market confidence and protects broader financial stability. Firms that align with these expectations are more likely to withstand examinations and reduce exposure to enforcement risk over time. 

Conclusion

The U.S. Securities and Exchange Commission has been a central pillar of American financial regulation for nearly a century, adapting its mandate to protect investors, ensure fair markets, and promote transparency. Its enforcement activity and AML compliance expectations continue to shape how firms manage risk and uphold regulatory obligations. 

As markets evolve, so too does the SEC’s role in guiding firms toward stronger controls and clearer investor protections, making it indispensable to any comprehensive compliance program.
