The government needs to blame itself for the credit crisis

Via Paul Kedrosky, Peter Wallison & Charles Calomiris explain how the government led us to the mortgage credit crisis:

..., it seems likely that the event responsible for the GSEs' change in direction and culture was the accounting scandal that each of them encountered in 2003 and 2004. In both cases, they lost their reputation as well-managed companies and began to encounter questions about their contribution to reducing mortgage rates and their safety and soundness. Serious observers questioned whether they should be allowed to continue to hold mortgages and MBS in their portfolios--by far their most profitable activity--and Senate Republicans moved a bill out of committee that would have prohibited this activity.

Under these circumstances, the need to manage their political risk became paramount, and this required them to prove to their supporters in Congress that they still served a useful purpose. In 2003, as noted above, Frank had cited an arrangement in which the GSEs' congressional benefits were linked to their investments in affordable housing. In this context, substantially increasing their support for affordable housing--through the purchase of the subprime loans permitted by HUD--seems a logical and even necessary tactic.

Unfortunately, the sad saga of Fannie and Freddie is not over. Some of their supporters in Congress prefer to blame the Fannie and Freddie mess on deregulation or private market failure, perhaps hoping to use such false diagnoses to lay the groundwork for reviving the GSEs for extra constitutional expenditure and political benefit in the future. As the future of the GSEs is debated over the coming months and years, it will be important to remember how and why Fannie and Freddie failed. The primary policy objective should be to prevent a repeat of this disaster by preventing the restoration of the GSE model.
