In 2005, the Senate Banking Committee, then under Republican control, adopted a strong reform bill, introduced by Republican Sens. Elizabeth Dole, John Sununu and Chuck Hagel, and supported by then chairman Richard Shelby. The bill prohibited the GSEs from holding portfolios, and gave their regulator prudential authority (such as setting capital requirements) roughly equivalent to a bank regulator. In light of the current financial crisis, this bill was probably the most important piece of financial regulation before Congress in 2005 and 2006. All the Republicans on the Committee supported the bill, and all the Democrats voted against it. Mr. McCain endorsed the legislation in a speech on the Senate floor. Mr. Obama, like all other Democrats, remained silent.

Now the Democrats are blaming the financial crisis on "deregulation." This is a canard. There has indeed been deregulation in our economy -- in long-distance telephone rates, airline fares, securities brokerage and trucking, to name just a few -- and this has produced much innovation and lower consumer prices. But the primary "deregulation" in the financial world in the last 30 years permitted banks to diversify their risks geographically and across different products, which is one of the things that has kept banks relatively stable in this storm.

As a result, U.S. commercial banks have been able to attract more than $100 billion of new capital in the past year to replace most of their subprime-related write-downs. Deregulation of branching restrictions and limitations on bank product offerings also made possible bank acquisition of Bear Stearns and Merrill Lynch, saving billions in likely resolution costs for taxpayers.
