Apparently, both parties have platform planks calling for the reinstatement of the Glass-Steagall Act of 1933, the law that separated investment banking from commercial banking until it was finally repealed in 1999 (after being watered down by the Federal Reserve beginning in the late 1980s). Bringing back Glass-Steagall in some form would force megabanks like JPMorgan Chase, Citigroup, and Bank of America to split up; it would also force Goldman Sachs to get rid of the retail banking operations it started in a bid to get access to cheap deposits.
In his article discussing this possibility, Andrew Ross Sorkin of the Times slips in this:
“Whether reinstating the law is good idea or not, the short-term implications are decidedly negative: It would most likely mean a loss of jobs as part of a slowdown in lending from the biggest banks.”
I looked down to the next paragraph for the explanation, but he had already moved on to another unsubstantiated claim (that the U.S. banking industry would be at a competitive disadvantage). So, I thought, maybe it’s so obvious that Glass-Steagall would reduce lending that Sorkin didn’t think it was worth explaining. I thought about that for a while. I couldn’t see it.
