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.
In 1999, the year many critics charge that the Clinton administration pressured Fannie and Freddie, the private sector sold into the secondary market just 18 percent of all mortgages.
Fueled by low interest rates and cheap credit, home prices between 2001 and 2007 galloped beyond anything ever seen, and that fueled demand for mortgage-backed securities, the technical term for mortgages that are sold to a company, usually an investment bank, which then pools and sells them into the secondary mortgage market.
About 70 percent of all U.S. mortgages are in this secondary mortgage market, according to the Federal Reserve.
