Investopedia explains Gramm-Leach-Bliley Act of 1999 - GLBA
Due to the horrific losses incurred as a result of 1929's Black Tuesday and Thursday, the Glass-Steagall act was created originally during the 1930s in order to prevent bank depositors from additional exposure to risk associated with stock market volatilities. As a result, for many years, banks were not legally allowed to act as brokers. Since many regulations have been instituted since the 1930s to protect bank depositors, GLBA was created to allow the financial industry to offer more services.
