The Glass-Steagall Act is a piece of financial legislation that dates to the Great Depression and has been partially dismantled but remains strikingly relevant today. The act has popped up repeatedly in a political context in recent months, and its future remains an open question.

Glass-Steagall was part of a broader set of 1933 regulations that prohibited FDIC-insured banks from investing in anything other than government bonds and similarly low-risk vehicles.

The law has spent the last 20 years under near-constant debate by politicians and economists alike. Some have blamed the financial crisis of 2008-09 on the partial repeal of the act in 1999, while others have suggested that the crisis was caused by actions unrelated to high-risk investments that the law had once prevented.

Glass-Steagall and the Banking Act of 1933

The Glass-Steagall Act is actually a set of provisions included in the broader Banking Act of 1933, a move to restore confidence in the banking system after thousands of bank failures in the first years of the Depression.

The Banking Act created the FDIC to safeguard consumers’ deposits at commercial banks and included the Glass-Steagall provisions to reduce the risk of providing such insurance.

Joseph E. Stiglitz, winner of a Nobel Prize in economics and a professor at Columbia University, wrote in a 2009 opinion piece:


“Commercial banks are not supposed to be high-risk ventures; they are supposed to manage other people’s money very conservatively. It is with this understanding that the government agrees to pick up the tab should they fail. Investment banks, on the other hand, have traditionally managed rich people’s money — people who can take bigger risks in order to get bigger returns.”

Glass-Steagall made commercial banks lower-risk and made it safer for the government to back those banks with deposit insurance, which would, in turn, prevent another Depression.

The partial repeal of Glass-Steagall

After decades of lobbying and proposed legislation, some Glass-Steagall provisions were repealed in 1999, when the Gramm-Leach-Bliley Act was signed. Glass-Steagall’s opponents had objected to what they perceived as over-regulation of the banking industry.

Among those who hold the repeal partly responsible for the 2008-09 financial crisis: John S. Reed and Sandy Weill, former chairmen of Citigroup, created in 1998 as Citibank acquired Travelers Insurance, which owned investment bank Salomon Smith Barney, effectively crossing the firewall between commercial and investment banking. Reed and Weill have said, in effect, that Glass-Steagall protected the U.S. economy until Gramm-Leach-Bliley was signed.

Others, including economists Paul Krugman and Mike Konczal and fact-checking outlet PolitiFact, have argued that Glass-Steagall would have done nothing to prevent the financial crisis because it didn’t cover the pure investment houses or the “shadow banks” whose risky behaviors most directly underwrote the crisis.

The Volcker Rule, or Glass-Steagall Light

Acting on the idea that the 2008-09 crisis resulted in part from a lack of sufficient separation, post-Glass-Steagall, between investment and commercial banking activities, Congress included the Volcker Rule in the Dodd-Frank reform bill, signed into law by President Barack Obama in 2010.

The part of Glass-Steagall known as Section 16, which was not repealed, limits the kinds of investments banks can make with customers’ deposit funds. Section 20, which was repealed, limited what banks could do even with their own money. The Volcker Rule reinstated some of the prohibitions of Section 20.

Potential issues with Volcker, including loopholes and gray areas that may impede enforcement, led to the introduction of the 21st Century Glass-Steagall Act. Four U.S. senators introduced the bill in summer 2015 seeking to revive the broader banking law.

The future of Glass-Steagall

The debate over financial regulation will hinge on the policy decisions of President Trump and a Republican-controlled Congress. Trump has said he would support a modern version of the law.

Trump, however, previously had called for the repeal of Dodd-Frank legislation and espoused a broader position against federal regulations on the private sector.
