What Is the Glass-Steagall Act?
The Glass-Steagall Act refers to specific provisions within the U.S. Banking Act of 1933 that mandated the separation of commercial banking from investment banking. This landmark legislation, a cornerstone of U.S. financial regulation for decades, aimed to protect depositors and stabilize the financial system during the Great Depression. The core intent of the Glass-Steagall Act was to prevent commercial banks, which accept customer deposits, from engaging in the inherently riskier activities associated with securities underwriting and trading. By creating this division, the Glass-Steagall Act sought to insulate the public's deposits from the speculative excesses of the capital markets.
History and Origin
The Glass-Steagall Act was enacted in response to the widespread bank failures and the stock market crash of 1929, which culminated in the Great Depression. During this period, a common concern was that commercial banks' involvement in speculative investment banking activities contributed significantly to the financial instability and loss of public trust. Banks had often used depositor funds for risky securities investments, leading to massive losses when the market collapsed.12
Introduced by Senator Carter Glass and Representative Henry Steagall, the legislation was designed "to provide for the safer and more effective use of the assets of banks, to regulate interbank control, to prevent the undue diversion of funds into speculative operations, and for other purposes."11 President Franklin D. Roosevelt signed the Banking Act of 1933, containing the Glass-Steagall provisions, into law on June 16, 1933.10 A critical component of the act was also the creation of the Federal Deposit Insurance Corporation (FDIC), which provided government-backed deposit insurance to protect customer funds.9
Key Takeaways
- The Glass-Steagall Act, part of the Banking Act of 1933, separated commercial banking from investment banking in the United States.
- Its primary goal was to prevent the speculative use of commercial bank deposits and restore public confidence in the banking system after the Great Depression.
- The Act prohibited commercial banks from underwriting or dealing in most securities, and limited their income from securities activities to 10%.
- It also prevented investment banks from taking deposits.
- Key provisions of the Glass-Steagall Act were repealed in 1999 by the Gramm-Leach-Bliley Act, leading to the re-integration of commercial and investment banking activities.
Interpreting the Glass-Steagall Act
The Glass-Steagall Act served as a strict framework for financial institutions, clearly delineating what activities were permissible for commercial banks versus investment banks. Under its regulation, a bank could either accept deposits and make loans (commercial banking) or engage in the sale and trading of securities (investment banking), but not both simultaneously within the same entity or through direct affiliations. This separation was intended to eliminate conflicts of interest where banks might push their own underwritten securities to clients or take excessive risks with depositor funds. The Act allowed for a limited exception, permitting commercial banks to underwrite government-issued bonds.
Hypothetical Example
Imagine a large financial conglomerate before the Glass-Steagall Act. This firm might operate a commercial banking division that accepts deposits from individuals and businesses, while also running an investment banking division that underwrites corporate bonds and stocks. If the investment banking division made poor decisions on its underwriting activities, leading to significant losses, those losses could directly impact the commercial banking side, potentially jeopardizing depositor funds.
After the Glass-Steagall Act, such a conglomerate would be forced to split into two distinct entities: one focusing solely on commercial banking, protected by deposit insurance, and another focusing purely on investment banking. The commercial bank would no longer be allowed to underwrite corporate securities, and its financial health would be insulated from the volatility of the securities markets. If the investment bank failed, the commercial bank's depositors would, in theory, remain safe.
Practical Applications
The Glass-Steagall Act profoundly shaped the structure of the U.S. financial industry for over sixty years. It created a system where banks specialized, fostering a period of relative stability in commercial banking and encouraging a clearer distinction between traditional lending and capital market activities.8 This separation influenced how banks managed their balance sheets, raised capital, and structured their product offerings. While the Act's main provisions were eventually repealed, its legacy continues to be debated in discussions about financial stability and the role of diversified financial institutions. The initial intent was to prevent the "undue diversion of funds into speculative operations," which directly impacted how banks operated and how the Federal Reserve System exercised its oversight.7
Limitations and Criticisms
Despite its long tenure, the Glass-Steagall Act faced increasing criticism over time. Opponents argued that the Act limited the competitiveness of U.S. banks against foreign banks, which often operated under universal banking models allowing them to conduct both commercial and investment banking activities.6 It was also argued that the Act stifled innovation and prevented banks from diversifying their revenue streams, potentially making them more vulnerable to economic downturns in a single sector.
The effectiveness of the Glass-Steagall Act in preventing financial crises was also debated, particularly after its repeal. While some economists and policymakers argued that the repeal contributed to the 2008 financial crisis, others contend that the crisis's causes lay elsewhere, such as in the subprime mortgage market and regulatory failures outside the scope of Glass-Steagall. Critics suggest that the Act had become largely ineffective even before its formal repeal due to regulatory interpretations and financial innovations that created loopholes.5 The core argument for reinstatement often centers on the idea of preventing "too big to fail" institutions and the potential for a "shadow banking system" to blur the lines between protected commercial banking and riskier activities.4
Glass-Steagall Act vs. Gramm-Leach-Bliley Act
The Glass-Steagall Act is often discussed in direct contrast to the Gramm-Leach-Bliley Act (GLBA) of 1999. While Glass-Steagall established a legal wall between commercial and investment banking, the GLBA effectively dismantled key provisions of this separation. The GLBA, also known as the Financial Services Modernization Act of 1999, repealed sections of the Glass-Steagall Act that prohibited affiliations between banks, securities firms, and insurance companies.
This repeal allowed commercial banks, investment banks, and insurance companies to merge and form integrated financial conglomerates. Proponents of the GLBA argued it would enhance competition and efficiency within the financial services industry, while critics warned of the potential for increased systemic risk and the blurring of regulatory lines. The GLBA aimed to adapt U.S. financial monetary policy to a more globalized and interconnected financial landscape.

There is ongoing debate among economists and policymakers regarding the extent to which the repeal of the Glass-Steagall Act contributed to the 2008 financial crisis. Some argue it played a role by allowing banks to become "too big to fail" and engage in riskier activities, while others contend that the primary causes were unrelated to the Act's repeal, such as failures in the housing market and other regulatory shortcomings.2
Who sponsored the Glass-Steagall Act?
