Nearly a century after the 1929 stock market crash erased fortunes and triggered the Great Depression, the federal watchdog created in its wake remains a central force in American financial regulation. The Securities and Exchange Commission, established by the Securities Exchange Act of 1934 and signed into law by President Franklin D.
Roosevelt, was Congress’s answer to a system that had lost the public’s confidence. Before the agency existed, securities oversight largely fell to individual states or to the industry itself—a structure that had proven unable to prevent the catastrophe that plunged the nation into economic turmoil.
Origins of a Federal Watchdog
The 1929 crash did more than wipe out fortunes; it shattered belief in the fairness of financial markets. Investors saw a system many considered rigged.
In response, Congress passed the Securities Exchange Act of 1934, giving the newly created SEC broad authority that had previously been absent. The agency was empowered to require public companies to disclose financial information, to ban manipulative practices, and to register stock exchanges and brokers. Its mandate, which has remained unchanged for nearly a century, rests on three pillars: protect investors, maintain fair and orderly markets, and facilitate capital formation. That framework has shaped the SEC’s enforcement reach over the decades.
The agency’s enforcement division built a record of pursuing some of the largest financial fraud cases in American history. The Bernie Madoff Ponzi scheme, uncovered in December 2008, stands as a landmark case, with estimated losses of $65 billion.
The Enron scandal of 2001 produced losses exceeding $60 billion. The following year, WorldCom’s collapse added another $11 billion in losses. In 2011, the insider trading case against Raj Rajaratnam resulted in $45 million in illicit profits.
The same year, the SEC brought charges against Goldman Sachs for misleading investors in subprime mortgage securities, a case that ended in a $550 million settlement.
New Frontiers in Enforcement
The agency’s enforcement actions have evolved to address new financial instruments that did not exist when the SEC was created. In 2020, the SEC filed charges against Ripple Labs, a case testing how securities laws apply to digital tokens.
More recently, in 2022, the agency brought charges against FTX founder Sam Bankman-Fried, involving losses estimated at $8 billion. These cases reflect the SEC’s effort to extend its traditional enforcement framework to cryptocurrency markets, where the definition of a security can determine how entire industries operate. The SEC’s enforcement budget has grown in tandem with its expanding responsibilities.
According to the agency’s records, it rose from $1.3 billion in fiscal year 2015 to $2.1 billion in fiscal year 2023. That spending supports a division that polices markets affecting anyone who owns stocks, bonds, or mutual funds.
For individual investors, the SEC’s work shapes the reliability of financial statements and the fairness of trading markets. The agency’s history shows that it is a product of a specific moment of market failure, designed to prevent a repeat of that catastrophe. As digital assets and decentralized finance challenge existing laws, the SEC’s role has once again come under scrutiny.
Its decisions about what constitutes a security can determine how entire industries operate. Understanding the SEC’s origins and its core purpose helps clarify why certain enforcement actions are taken and what the agency can and cannot do.
From the wave of corporate accounting scandals in the early 2000s to the collapse of major cryptocurrency platforms, the SEC has sought to apply its traditional framework to novel situations. The record of cases stretching from Enron and WorldCom to Madoff, Goldman Sachs, Rajaratnam, Ripple Labs, and FTX illustrates an agency that has repeatedly adapted its enforcement priorities to match the financial landscape it was created to police.
