I do not know much about this claim with Buffet and Mark to Market.
However, I have seen no evidence that it was involved in the sub-prime crash directly.
And I would agree that GWB was also supportive of more home ownership. That is true. Both parties were. That is true.
However, the sub-prime crash's origins were in 1997. This is clearly documented.
In 1997, the housing prices started to spike up.
This increase in housing prices coincides directly with the increase in sup-prime mortgages that happened in 1997.
Before 1997, sub-prime loans were a niche market, specifically because they were risky.
So what happened on or before 1997 that caused the dramatic increase in sub-prime loans?
Two things..... First Freddie Mac started guaranteeing sub-prime loans.
Wachovia Press Releases
First Union Capital Markets Corp. and Bear, Stearns & Co. Inc. have priced a $384.6 million offering of securities backed by Community Reinvestment Act (CRA) loans - marking the industry's first public securitization of CRA loans.
The $384.6 million in senior certificates are guaranteed by Freddie Mac and have an implied "AAA" rating. First Union Capital Markets Corp. is the investment banking subsidiary of First Union Corporation.
First Union became Wachovia, which means the two original companies involved in Freddie Mac's guarantee of sub-prime loans, both ended up crashing spectacularly during the sub-prime crash.
So to recap, the government through Freddie Mac was pushing sub-prime loans.
At the exact same time, the government was taking banks to court, for not making risky sub-prime loans.
Andrew Cuomo, then part of the Clinton administration, forced banks through the court, to make sub-prime loans.
Between the government using Freddie Mac to guarantee sub-prime loans, and giving them implied AAA ratings, and the Government suing banks in court for not making sub-prime loans....
This is what caused the sub-prime crash.
