Quote from MKTrader:
GSEs + super low rates courtesy of the Fed + CRA and other gov't "encouragement" to push (force) banks to lend was a recipe for disaster.
The subprime disaster wouldn't have just randomly popped up without it. Investors, traders and house-flippers simply took what they were given and tried to squeeze every dime out of it, just like every other bubble.
GSEs were definitely problematic. They were not the <i>root cause</i> of the crisis by any stretch of the imagination. It is a convenient scapegoat of market fundamentalist types who abhor looking at data.
The biggest lenders were non-banks <i>not</i> covered by the CRA. After the banks got involved, they were chasing fat profits, not out of a public mandate. The vast majority of loans were bought by Wall St., not GSEs -- i.e., the percentage of the subprime loan market represented by what was ultimately on the Fed's balance sheet was a fraction of the total market.
I do agree that low rates played a causal role in the speculation, but that has nothing to do with Fannie and Freddie. I am just not hindered by a need to chase away cognitive dissonance that would rub my ideological positions the wrong way.
