Maybe. Then again, probably not, and definitely not all on its own.

We are now ten years removed from the beginning of the financial crisis that would become the Great Recession, and after all that time the mainstream explanation for the crisis can be summed up in one word: deregulation.

But, what deregulation? That is where the stories get more complicated. One theory that has risen to prominence is that the repeal of the Glass-Steagall Act of 1933, by way of the Gramm-Beach-Bliley Act, is to blame. Another theory argues that regulation of the banking system had ostensibly been unraveling since the Reagan Administration, and that it was only a matter of time before fraud and abuse of the system reached critical mass and the house of cards collapsed.  However, there are serious problems with both these theories and many others that are so haphazardly thrown out as a panacea-like explanation for something as complicated as the housing boom and bust, and subsequent Great Recession.

On this ten-year anniversary, these topics temporarily become salient in the public discourse once again. Therefore, why not take the opportunity to flip (at least part) of the accepted narrative on its head?

What follows is a short summary of only a few of the problems with the deregulation as boogeyman hypothesis; this is not a research article, but a polemical and by no means comprehensive response to a narrative that will not die no matter how many times you shoot it, and always catches up no matter how fast you run away.

Glass-Steagall repeal is the ultimate strawman. The Gramm-Beach-Bliley Act that supposedly repealed Glass-Steagall prohibitions against financial and commercial bank collusion, in fact, did nothing of the sort. Glass-Steagall did four things: 1) prohibited banks from underwriting or dealing in securities; 2) prohibited dealers in securities from taking commercial deposits; and, in two final provisions, essentially prohibited commercial banks from being affiliated with or existing under the same holding company as firms that dealt in securities.

The so-called repeal only removed the final prohibitions. Commercial banks are still prohibited from dealing in securities. However, even if repeal had been total, the legislation would have had nothing to do with the crisis. The housing bust and the financial crisis occurred because commercial banks failed in the performance of traditional banking activities; they made poor loans and invested in overvalued mortgage-backed securities (MBS). The US economy did not crater because commercial banks started dealing in complex financial instruments, both because that is not the purpose for which they were chartered and because to do so would be in violation of federal law.

But were commercial banks existing under the same corporate umbrella as financial institutions pressured into taking on toxic MBSs and other assets that their securities firm brethren were desperate to unload? Hardly. Commercial banks invested in MBSs because they were rated AAA by a government-licensed cartel of ratings agencies. For a long time, MBSs provided a substantial ROI, and commercial banks were desperate to hold them because of the minimal reserve capital requirements necessary to do so. Banks could lend out significantly more of their reserves because they were holding AAA-rated paper. Commercial banks did not need an edict from their corporate overlords. The prospect of solid, consistent returns and minimal capital requirements was incentive enough to hold these assets.
