I understand that the loan packages were put together to keep the defaults to some allowable level, and that they didn’t ever think there would be no defaults. In the past housing busts were confined to various regions, this was the first that was nationwide.
As for prepayment, I had the impression that many of these loans had significant prepayment penalties in states which allowed this. I also thought that the loans were sold by saying that the borrower could refinances (given his increase house price) before the interest rate ballooned. Was the prepayment concern based on this?
Did the banks actually understand how bad Countrywide’s underwriting standards were? Did they try to push back on them, or did they not care because higher rates meant more money and they were dumping the stuff anyhow?
A lot of regulation was supposedly in place, in the hands of the Fed and various agencies. Now, if the President sends a clear message that regulation is bad, these agencies are not going to be very active. And, if you remember, the states attorney generals tried to do something, but Greenspan shot it down.
Those in Congress against regulation - either from ideology or from cash - deserve a lot of blame, but it is not only them.
Great depression was worse but no one thought that anythig close to that could happen.
The we prepayment assumptions and the strips were priced based on those prepayment assumptions. A very common form of stripping was to strip interest payments from principal payments. The returns on these things are very prepayment rate sensitive.
They punished countrywide paper but not by anywhere near enough to account for the poor quality of the junk they were writing.
