Spooked by Glass-Steagall’s Ghost?

CAMBRIDGE – America’s long-controversial Glass-Steagall Act of 1933, which separated deposit-taking commercial banks from securities-trading investment banks in the United States, is back in the news. This separation long symbolized America’s unusual history of bank regulation – probably the most unusual in the developed world. 

American banking regulation had long kept US banks small and local (unable to branch across state lines), unlike their European and Japanese equivalents, while limiting their operational capacity (by barring banks from mixing commercial and investment banking). These limits on American banking persisted until the 1990’s, when Congress repealed most of this regulatory structure. Now the idea of a new Glass-Steagall is back, and not only in the US.
