The underlying problem is that the U.S. government (via the FDIC) has insured bank deposits up to $250,000. In addition to this, the U.S. government recently underwrote quite bit of bank debt. Finally, there are all sorts of implicit though fuzzy guarantees from the government. Those are the things that need to change.
If the government is underwriting financial firms, it will want to hold them to certain standards. There are already lots of such standards in place, and this idea of limiting what banks can do will be one more. Government standards are usually bureaucratic and inefficient. Still, it is the underlying guarantee that needs to be undone.
There are a lot of underlying problems. In this mess, it was the gov’t guaranteeing risk for Fannie and Fred so they could sell MBS to Wall Street that was a big problem. Once Fan and Fred allowed banks to short circuit the reserve limits on total mortgage loans, all bets were off. And if that wasn’t bad enough, when the loans started falling off because credit demand dried up, the gov’t loosened lending standards, created exotic loans that were not really loans but gov’t-sponsored speculative leveraging, and talked up that speculation:
Calculations by market analysts of the “option adjusted spread” on mortgages suggest that the cost of these benefits conferred by fixed-rate mortgages can range from 0.5 percent to 1.2 percent, raising homeowners’ annual after-tax mortgage payments by several thousand dollars. Indeed, recent research within the Federal Reserve suggests that many homeowners might have saved tens of thousands of dollars had they held adjustable-rate mortgages rather than fixed-rate mortgages during the past decade

This from the man who held the controls of interest rates over that decade.
It wasn’t long before FHA was opening up Option ARM’s with nothing down to first time homebuyers with barely enough income to cover the minimum payments and no assets to fall back on, save what they could gain from equity inflation after the purchase.
If the government had consciously engineered a massive bubble and credit collapse, they could not have been more effective than the Fed, FHA, Congress and the GSE’s were in this case. They did everything exactly right.
