Interesting. I've been thinking that the backstory to the explosion of subprime lending since 2003 had a lot to do with excessive capital taking higher risks in search of higher returns. The dot com crash in 2000, Enron and similar scandals in 2001-2002 and Sarbanes Oxley reforms in 2002 killed returns in stocks. That capital had to seek returns elsewhere, and this led to the explosion of hedge funds, private equity funds and the like. It's not surprising that a lot of this money found its way into the mortgage market. The implication for mortgages is that once these funds have been burned, they will stay away from the mortgage business just as they have stayed away from public stocks since the dot com crash. In other words, all that capital is gone, and its not coming back to residential mortgages.
