“The repeal enabled Wall Street to take risky actions with money deposited in commercial banks.”

The claim that the repeal of the Glass-Steagall Act's affiliation restrictions via the Gramm-Leach-Bliley Act (GLBA) of 1999 "enabled Wall Street to take risky actions with money deposited in commercial banks" is directionally supported but oversimplifies the mechanism. What GLBA actually did: It repealed Sections 20 and 32 of the Banking Act of 1933, which had prohibited affiliations and management interlocks between commercial banks and securities firms. This authorized the creation of "financial holding companies" (FHCs) — umbrella organizations that could own both commercial bank subsidiaries and investment bank/insurance subsidiaries under common ownership. What GLBA did NOT do: It left Sections 16 and 21 of Glass-Steagall intact. Section 16 continued to prohibit depository institutions themselves from underwriting, dealing in securities, or engaging in proprietary trading. Section 21 continued to prohibit securities firms from accepting deposits. Firewalls (Sections 23A and 23B of the Federal Reserve Act) restricted transactions between banking and nonbanking affiliates within an FHC. So commercial banks could not literally take depositors' money and gamble with it in securities markets; the integration was at the holding-company level, not within a single legal entity. Evidence supporting a causal link: - A peer-reviewed study in the Journal of Financial Research (2004) found that banks experienced an increase in risk regardless of active participation in investment banking after GLBA, attributing this to the greater inherent riskiness of the securities business. - A study in the Journal of Money, Credit and Banking (2009) found that increased participation in investment banking was associated with higher total and unsystematic risks in the period of deregulation culminating in GLBA. - The Congressional Research Service report (R44349) notes the debate is about "whether to permit inherently risky commercial and investment banking activities to be conducted within a single firm—specifically within firms holding federally insured deposits," and cites evidence that securities offerings through universal bank channels had significantly higher default rates than those through unaffiliated broker-dealers. Evidence contesting or qualifying the link: - The CRS report explicitly states that some policymakers argue Glass-Steagall issues were not significant causes of the crisis, and that the Act would have made responding to the crisis more difficult if it had remained in place. - The Federal Reserve History essay notes that most major Wall Street investment banks did not reorganize as FHCs prior to the financial crisis, raising questions about how much the repeal actually drove the crisis. - The OCC's working paper characterized GLBA as "ratifying, rather than revolutionizing" banking practice, since the separation had been eroding for decades through regulatory and judicial actions. - The CRS report concludes that the erosion and repeal of the Glass-Steagall Act's affiliation restrictions was "probably not the primary cause of the growth of" the mortgage crisis. Assessment: The affiliation permitted under GLBA did create conditions where riskier securities activities could be conducted within the same corporate structure as federally insured deposits, and academic evidence confirms increased bank risk post-GLBA. However, the claim oversimplifies the mechanism: the repeal did not allow direct use of deposits for securities trading, but rather permitted common ownership through holding companies with regulatory firewalls. The causal significance of the repeal for the 2007–08 financial crisis remains debated among experts, with credible arguments on both sides. The link is reasonable and supported by evidence, but not decisively established as a major or decisive driver.
