Last week, it was a $200 billion cash-for-bond swap for the banks. This week, it was a $200 billion bond-for-bond swap for the big investment houses. If they keep this up, pretty soon you'll be able to walk into any Federal Reserve bank and hock that diamond brooch you inherited from Aunt Mildred. Forget all that nonsense about the Bernanke Fed being too timid or behind the curve. In the face of what is turning into the most serious financial market crisis since the Great Depression, the Fed has been more aggressive and more creative in using its limitless balance sheet -- in effect, its ability to print money -- than at any time in history. We can argue till the cows come home about whether this is a bailout for Wall Street. It is -- but only to the extent that it is also a bailout for all of us, meant to prevent a financial and economic meltdown that drags everyone down with it. In broad strokes, we're going through a massive de-leveraging" of the economy, wringing out trillions of dollars of debt that had artificially driven up the price of real estate and financial assets, and, more generally, allowed Americans to live beyond their means. Fed officials warn that this de-leveraging is nowhere near finished. It's anyone's guess how long this credit crunch will last, but the chances are that we'll have several more market meltdowns and Fed rescues before it's over, probably in the fall. Until then, the dollar will continue to get hammered and stocks will continue their fitful decline. And if the last two financially induced recessions are any guide, it will be well into 2009 before the economy hits bottom, followed by a couple of years of slow growth and "jobless" recovery.
