Writing in the WSJ, Alan Greenspan argues
that the Fed did not cause the housing bubble because the
historically low mortgage rates that triggered the boom were not
a result of Fed rate cuts, but of changes in the global economy.
It's worth noting that during the height of the housing boom,
Greenspan denied that a national housing bubble was possible.
Here's what he had to say at an October 19, 2004
speech at America's Community Banker's Annual Convention:
Overall, while local economies may experience significant
speculative price imbalances, a national severe price
distortion seems most unlikely in the United States, given its
size and diversity.
