The Fed was hardly alone in not pressing to clean up the mortgage industry. When states like Georgia and North Carolina started to pass tougher laws against abusive lending practices, the Office of the Comptroller of the Currency successfully prohibited them from investigating local subsidiaries of nationally chartered banks.

What about the charge that Fannie and Freddie "made" the market so that all these subprime loans could be securitized? There's a grain of truth in there, but I think keeping in mind which loans are going bad is useful, when reading this excerpt.

This much is true. In an effort to promote affordable home ownership for minorities and rural whites, the Department of Housing and Urban Development set targets for Fannie and Freddie in 1992 to purchase low-income loans for sale into the secondary market that eventually reached this number: 52 percent of loans given to low-to moderate-income families.

To be sure, encouraging lower-income Americans to become homeowners gave unsophisticated borrowers and unscrupulous lenders and mortgage brokers more chances to turn dreams of homeownership in nightmares.

But these loans, and those to low- and moderate-income families represent a small portion of overall lending. And at the height of the housing boom in 2005 and 2006, Republicans and their party's standard bearer, President Bush, didn't criticize any sort of lending, frequently boasting that they were presiding over the highest-ever rates of U.S. homeownership.

Between 2004 and 2006, when subprime lending was exploding, Fannie and Freddie went from holding a high of 48 percent of the subprime loans that were sold into the secondary market to holding about 24 percent, according to data from Inside Mortgage Finance, a specialty publication. One reason is that Fannie and Freddie were subject to tougher standards than many of the unregulated players in the private sector who weakened lending standards, most of whom have gone bankrupt or are now in deep trouble.

During those same explosive three years, private investment banks -- not Fannie and Freddie -- dominated the mortgage loans that were packaged and sold into the secondary mortgage market. In 2005 and 2006, the private sector securitized almost two thirds of all U.S. mortgages, supplanting Fannie and Freddie, according to a number of specialty publications that track this data.

Now, again, consider which subprime loans, in the graph below, went bad...

Notice that the delinquency rate is highest in the years after Fannie and Freddie are constrained in terms of their subprime holdings.
