I don’t know; it seems like there are rumblings that the Fed will imminently take action, and that does not resonate with me. You can also read the stuff from Doug Kass at RealMoney, or consider the rebirth of the Plunge Protection Team. We are not so far from the next Fed meeting that waiting would make that much of a difference, particularly since the Fed tipped its hand when Bernanke spoke recently. There is a decent-sized cut coming, and the Treasury yield curve reflects it.
Now, I have my doubts as to the long-term efficacy of unusual measures from the Fed or the Treasury. You can’t get something by government fiat. Even a Fed Governor thinks we expect too much from the Fed, a sentiment with which I heartily agree, even though the Fed is partially responsible for creating that illusion. If the Fed took more of a “we do our best, but our powers are not that large in the long run” approach, market players might not give them so much credence.
Now, I’m not going so far as Anna Schwartz, who thinks the current Fed isn’t up to the task. That may or may not be true; what is hard to dispute is that Alan Greenspan dealt the existing FOMC a bad hand from a prior monetary policy that too easily responded to minor crises, rather than letting the economy take some pain. Moderate recessions are good for the economy; save the heroics for depression-like conditions.
