Just as the Fed's overnight window dwarfed TARP in the 2008 panic.
Mish hits a homer, here:
I have little doubt the Fed (central bankers in general) will step on the money supply spigot in response to another slowdown. But credit dwarfs money supply. Once again, those who view inflation and deflation in the myopic eyes of money supply alone will come to the wrong conclusions about prices of goods, services and assets, just as they did in 2008 when they thought hyperinflation was just around the corner. Those who understand credit and credit market to market will get the picture right. I repeat my claim that I made in 2007. The US will go in and out of deflation over the course of a number of years. Deflation is once again nearly at hand, but Europe will be first.
