Blame Fannie Mae and Congress For the Credit Mess
Many monumental errors and misjudgments contributed to the acute financial turmoil in which we now find ourselves. Nevertheless, the vast accumulation of toxic mortgage debt that poisoned the global financial system was driven by the aggressive buying of subprime and Alt-A mortgages, and mortgage-backed securities, by Fannie Mae and Freddie Mac. The poor choices of these two government-sponsored enterprises (GSEs) -- and their sponsors in Washington -- are largely to blame for our current mess.

How did we get here? Let's review: In order to curry congressional support after their accounting scandals in 2003 and 2004, Fannie Mae and Freddie Mac committed to increased financing of "affordable housing." They became the largest buyers of subprime and Alt-A mortgages between 2004 and 2007, with total GSE exposure eventually exceeding $1 trillion. In doing so, they stimulated the growth of the subpar mortgage market and substantially magnified the costs of its collapse.

It is important to understand that, as GSEs, Fannie and Freddie were viewed in the capital markets as government-backed buyers (a belief that has now been reduced to fact). Thus they were able to borrow as much as they wanted for the purpose of buying mortgages and mortgage-backed securities. Their buying patterns and interests were followed closely in the markets. If Fannie and Freddie wanted subprime or Alt-A loans, the mortgage markets would produce them. By late 2004, Fannie and Freddie very much wanted subprime and Alt-A loans. Their accounting had just been revealed as fraudulent, and they were under pressure from Congress to demonstrate that they deserved their considerable privileges. Among other problems, economists at the Federal Reserve and Congressional Budget Office had begun to study them in detail, and found that -- despite their subsidized borrowing rates -- they did not significantly reduce mortgage interest rates. In the wake of Freddie's 2003 accounting scandal, Fed Chairman Alan Greenspan became a powerful opponent, and began to call for stricter regulation of the GSEs and limitations on the growth of their highly profitable, but risky, retained portfolios.

If they were not making mortgages cheaper and were creating risks for the taxpayers and the economy, what value were they providing? The answer was their affordable-housing mission. So it was that, beginning in 2004, their portfolios of subprime and Alt-A loans and securities began to grow. Subprime and Alt-A originations in the U.S. rose from less than 8% of all mortgages in 2003 to over 20% in 2006. During this period the quality of subprime loans also declined, going from fixed rate, long-term amortizing loans to loans with low down payments and low (but adjustable) initial rates, indicating that originators were scraping the bottom of the barrel to find product for buyers like the GSEs.

The strategy of presenting themselves to Congress as the champions of affordable housing appears to have worked. Fannie and Freddie retained the support of many in Congress, particularly Democrats, and they were allowed to continue unrestrained. Rep. Barney Frank (D., Mass), for example, now the chair of the House Financial Services Committee, openly described the "arrangement" with the GSEs at a committee hearing on GSE reform in 2003: "Fannie Mae and Freddie Mac have played a very useful role in helping to make housing more affordable . . . a mission that this Congress has given them in return for some of the arrangements which are of some benefit to them to focus on affordable housing." The hint to Fannie and Freddie was obvious: Concentrate on affordable housing and, despite your problems, your congressional support is secure....
