Professorn i nationalekonomi vid New York University Mario Rizzo om krisens grundorsak:

We must remember that the current economic state of affairs was caused by the excessively low interest-rate policy followed by the Federal Reserve from about mid-2002 through the third quarter of 2006. This policy resulted in significant economic distortions or imbalances. To say that it was “caused” by the Fed’s policy is not to say that once this occurred that other problems in the financial sector did not play a significant compounding role. Yet, were it not for the unsustainable misdirection of resources that we are now calling the “housing bubble” we would not be faced with our current major problems.
