Key Takeaways

Sure, here are three main points about the Glass-Steagall Act written in HTML:“`html

  1. The Glass-Steagall Act was a U.S. legislation passed in 1933, during the Great Depression, that separated commercial and investment banking to avoid conflicts of interest and risk exposure.
  2. By creating a wall between commercial and investment banking activities, the act aimed to prevent the type of speculative investments that led to the Wall Street Crash of 1929.
  3. The Act was partially repealed in 1999 by the Gramm-Leach-Bliley Act, which allowed commercial banks, investment banks, and insurance companies to consolidate. Some critics argue the repeal of Glass-Steagall contributed to the 2008 financial crisis.



The Glass-Steagall Act, passed in 1933, is significantly important in the field of business/finance as it established a clear separation between commercial and investment banking activities to protect consumers. Following the disastrous 1929 market crash and the Great Depression, it was enacted to avoid conflicts of interest and risky investment activities by commercial banks, thereby preventing banking crises. It emphasized the safety of depositors’ money, further strengthening the public’s trust in the banking system. Despite its partial repeal through the Gramm-Leach-Bliley Act in 1999, debates around its significance grow louder during discussions of financial regulation and systemic risk mitigation.


The Glass-Steagall Act, formally known as the Banking Act of 1933, was primarily framed to establish a barrier against the commingling of commercial and investment banking activities, in order to ensure financial stability and prevent a recurrence of the financial collapse that led to the Great Depression. In other words, its purpose was to curb banks from becoming overly speculative in their investment pursuits, thereby limiting risks associated with financial speculation and safeguarding depositors’ funds. The notion was to ensure that the role of commercial banks remained confined to taking deposits and making loans, while investment banks should engage in underwriting and dealing in securities, without intertwining these activities.The provision of creating this banking reform acted as a safeguard or protective mechanism for consumer interests. It was purposed to ward off the potential for conflicts of interest and harmful speculation that could occur when banks were permitted to both take and safeguard deposits and underwrite securities. The Glass-Steagall Act also established the Federal Deposit Insurance Corporation (FDIC) that provided the security of deposit insurance, imparting depositor’s confidence in the banking system. Hence, the usage of this act has been significant in the delineation of the banking sector and ensuring its robustness.


1. J.P. Morgan Chase: Prior to the passage of the Glass-Steagall Act in 1933, J.P. Morgan & Co. was a large, integrated financial institution that engaged in both commercial and investment banking. After the Act was passed, the company had to split its operations in order to comply with the new regulation – its commercial banking operations became J.P. Morgan & Co., and its investment banking operations were spun off into a new firm, Morgan Stanley.2. Citigroup: In 1998, Citicorp (a commercial bank holding company) and Travelers Group (an insurance and securities firm) agreed to merge. However, due to the fencing off regulations of the Glass-Steagall Act, they needed the Act to be repealed for the merger to fully be effective. The merger was a driving force behind the Gramm-Leach-Bliley Act of 1999, which indeed repealed parts of the Glass-Steagall Act, allowing commercial banks, investment banks, securities firms, and insurance companies to consolidate, and thus Citigroup became the first fully combined financial services company of its kind in the US.3. Bank of America and Merrill Lynch: In the midst of the 2008 financial crisis, one year after the Glass-Steagall Act was repealed, Bank of America, a commercial bank, acquired Merrill Lynch, a major investment bank. Without the repeal of the Act, this consolidation of financial operations would have been against the law. This consolidation is considered an example of the effects of the repeal of the Glass-Steagall Act.
