Since late summer, the US Federal Reserve has been attempting to manage the slow-moving financial crisis triggered by the collapse of the US housing bubble.
At the start, the Fed assumed that it was facing a first-mode crisis -- a mere liquidity crisis -- and that the principal cure would be to ensure the liquidity of fundamentally solvent institutions.
But the Fed has shifted over the past two months toward policies aimed at a second-mode crisis -- more significant monetary loosening, despite the risks of higher inflation, extra moral hazard and unjust redistribution.
As Fed Vice Chair Don Kohn recently put it: "We should not hold the economy hostage to teach a small segment of the population a lesson."
No policymakers are yet considering the possibility that the financial crisis might turn out to be in the third mode.
This is a scariest thing I've read in the past few months.
