The term
Glass–Steagall Act usually refers to four provisions of the U.S.
Banking Act of 1933 that limited commercial bank securities, activities, and affiliations within commercial banks and securities firms. Congressional efforts to "repeal the Glass–Steagall Act" referred to those four provisions (and then usually to only the two provisions that restricted affiliations between commercial banks and securities firms ). Those efforts culminated in the 1999
Gramm–Leach–Bliley Act (GLBA), which repealed the two provisions restricting affiliations between banks and securities firms.
