Erm no. 2008 was directly linked to Greenspan (Fed), Freddie Mac (Federal) and Fannie Mae (Federal), all government run entities, which stopped making proper risk evaluation when issuing loans. That's not deregulation, that's a problem with how these government agencies actually functioned.

> If not the boldest of the group, then at least the most public, Greenspan, the man many are now blaming for the housing bubble (there were a brave few that piped up years ago), has refused to go quietly into his well-padded retirement. The man charged with providing the country with a financial voice of reason fell far short, so much so that it might be comical if it weren't so tragic.
> Greenspan's denial of the possibility of a housing bubble has been widely derided in the past year, but a single statement could be excused as human error. However, a quick scan shows that this wasn't a single event. He also promoted the adoption and expansion of adjustable-rate mortgage (ARM) products in early 2004, when short-term rates were at or near historic lows. That same year he claimed, "securitization by Fannie and Freddie allows mortgage originators to separate themselves from almost all aspects of risk associated with mortgage lending." And separate themselves they did, ceasing to perform any kind of due diligence as to the ability of borrowers to pay for the homes they were buying.
