enabled Wall Street banks to market high rate (i.e. composed of subprime loans) CDOs (Collaterized Debt Obligations) to institutional investors because they sold them CDSs along with them. They told the institutional invesors that the CDSs would protect the investor against loss due to default. OF course, the banks then went and bought CDSs from AIG to cover
themselves against loss, should they have to pay off their customers in case of defaults. But they needed high rate CDOs to interest the investors. Ordinary low rate mortgage loans were of no interest (no pun intended).
It was this demand for the high rate (composed of subprime loans) CDOs from Wall street that pushed the predatory lenders to beat the bushes for suckers. Admittedly, many people signed up for loans they should have known better than to sign up for. Many, many people did think the pumped up houseing market (thanks to overly expansionist monetary policies at the Fed) would just keep on going up. And they thought the party would go on forever and they would, in a few years, sell their house or condo for more than they paid for it and get into something even more expensive. And they got in way over their heads.
The subprime market really took off after 2000 - about 2002 really. This was after the CFMA made CDSs legal and unregulated.
The Comptroller of the Currency stopped 50 states attorneys General from going after predatory lenders (using consumer protection laws)
in 2004.
The Comptr of the Currency also
went to court to stop Eliot Spitzer then attorney gen of state of New York from investigating (with intent to prosecute) predatory lenders in NY.
