Summary

The Glass-Steagall Act refers to four provisions within the United States Banking Act of 1933, enacted in response to the speculative excesses leading to the 1929 Stock Market Crash and the Great Depression. Sponsored by Senator Carter Glass and Representative Henry B. Steagall, this landmark legislation aimed to prevent future banking crises by separating commercial and investment banking. It prohibited securities firms from accepting deposits and restricted commercial banks from engaging in various non-governmental securities activities or affiliating with securities firms. While federal regulators began to loosen interpretations of the Act in the early 1960s, its key provisions restricting affiliations were ultimately repealed by the Gramm-Leach-Bliley Act in 1999. The role of this repeal in the 2008 financial crisis remains a subject of debate among economists and commentators.

Glass–Steagall legislation

The Glass–Steagall legislation describes four provisions of the United States Banking Act of 1933 separating commercial and investment banking. The article 1933 Banking Act describes the entire law, including the legislative history of the provisions covered. As with the Glass–Steagall Act of 1932, the common name comes from the names of the Congressional sponsors, Senator Carter Glass and Representative Henry B. Steagall. The separation of commercial and investment banking prevented securities firms and investment banks from taking deposits and commercial Federal Reserve member banks from: dealing in non-governmental securities for customers; investing in non-investment grade securities for themselves; underwriting or distributing non-governmental securities; affiliating (or sharing employees) with companies involved in such activities. Starting in the early 1960s, federal banking regulators' interpretations of the Act permitted commercial banks, and especially commercial bank affiliates, to engage in an expanding list and volume of securities activities. Congressional efforts to "repeal the Glass–Steagall Act", referring to those four provisions (and then usually to only the two provisions that restricted affiliations between commercial banks and securities firms), culminated in the 1999 Gramm–Leach–Bliley Act (GLBA), which repealed the two provisions restricting affiliations between banks and securities firms. By that time, many commentators argued Glass–Steagall was already "dead". Most notably, Citibank's 1998 affiliation with Salomon Smith Barney, one of the largest U.S. securities firms, was permitted under the Federal Reserve Board's then existing interpretation of the Glass–Steagall Act. In November 1999, President Bill Clinton publicly declared "the Glass–Steagall law is no longer appropriate". Some commentators have stated that the GLBA's repeal of the affiliation restrictions of the Glass–Steagall Act was an important cause of the 2008 financial crisis. Nobel Memorial Prize in Economics laureate Joseph Stiglitz argued that the effect of the repeal was "indirect": "[w]hen repeal of Glass-Steagall brought investment and commercial banks together, the investment-bank culture came out on top". Economists at the Federal Reserve, such as Chairman Ben Bernanke, have argued that the activities linked to the 2008 financial crisis were not prohibited (or, in most cases, even regulated) by the Glass–Steagall Act.
