What is the Gramm-Leach-Bliley Act of 1999 (GLBA)?
Congress enacted the bipartisan Gramm-Leach-Bliley Act of 1999 (GLBA) on November 12, 1999. GLBA sought to modernize the financial industry. GLBA is most known for repealing the 1933 Glass-Steagall Act, which prohibited commercial banks from offering financial services like investments and insurance as part of their operations.
The 1999 Gramm-Leach-Bliley Act
After the devastating losses of 1929’s Black Tuesday and Thursday, the Glass-Steagall Act was established to safeguard bank depositors from stock market volatility-related risks. Commercial banks were ineligible to serve as brokers for many years.GLBA allowed financial industry participants to provide additional services due to rules enacted during the 1930s to safeguard bank depositors.
Citicorp’s acquisition of Travelers Group prompted GLBA. The conglomerate Citigroup combined commercial banking, insurance, and securities business lines. Its brands were Citibank, Smith Barney, Primerica, and Travelers. The Citicorp acquisition violated the Glass-Steagall Act and the Bank Holding Company Act of 1956.
This act is also known as the Gramm-Leach-Bliley Financial Services Modernization Act.
To facilitate the merger, the U.S. Federal Reserve granted Citigroup a temporary waiver in September 1998 before the GLBA’s ratification by Congress. Similar mergers would be legal in the future. Repealing Glass-Steagall allowed “simultaneous service by any officer, director, or employee of a securities firm as an officer, director, or employee of any member bank.”
GLBA and Consumer Privacy
The Gramm-Leach-Bliley Act mandated financial firms providing loan services, financial advice, or insurance to disclose their information-sharing activities to clients. Customers must be able to “opt out” of sharing sensitive data with companies.
Many think bank balances and account numbers are private, yet banks, credit card firms, and others buy and sell them. Gramm-Leach-Bliley mandated minimal privacy safeguards against data sales and pretexting.
Conclusion
- This late 1999 law permits banks to offer financial services formerly prohibited by the Glass-Steagall Act.
- Managers and service providers can only sell or manage one financial product or instrument under the GLBA.
- All banks must notify customers of their information-sharing procedures.
