Wouldn;t raising interest rates do that?
In a way, yes. The central bank would essentially suck up some of the excess dollars.
We're in a lot of really bad financial straits right now. The debt-backed economy is on the ropes, and that could potentially amount to a
9 times world GDP net loss in the worst case scenario.
That's roughly 500 Trillion dollars going "poof". That's about the worst thing that could happen to our species right now, as food wouldn't even be available to most of the world as a result. [this is the doomsday prediction right now, and may not be too likely]...
...That's assuming a lot of really bad things start happening:
1. Accelerated mortgage defaults (60 minutes has ENCOURAGED people to walk away). These are already here.
2. A continued credit crunch, as banks won't lend the money the Fed is giving them, because they're just using it to build back the capital that they've already written off...which is growing as more people walk away.
3. A resulting massive slow-down in the economy (more so than we're already seeing). As people realize the credit crunch is here and start saving everything they can.
4. A transfer of the loan defaults to other loan types: e.g. credit cards, auto loans, etc. This is already beginning.
5. A "calling out" of the bonds insurers by the industry raters as its seen that their assets are backed solely by increasingly defaulted loans. That means they're next to worthless houses and cars and consumer "junk" that is completely non-liquid, and way too over-supplied for the shrinking consumer base during the recession phase.
6. The resulting collapse of the "house of cards" economies around the world as the markets go under.
The bulk of financial assets are incredibly non-liquid right now, and the first domino to go (well, not really the first...) has been over-priced housing.
Unfortunately, the homes have been the source of income for too many families who kept refinancing. Now that's going bye-bye. So here comes the recession which may spur this whole shebang.
But I'm no expert. This is just from reading between the lines. The Fed knows all of this risk, and has cut rates as a last resort to try to stave off the credit crunch and run-to-savings. They were not (IMO) just trying to pander to Wall Street. This is the big deal of the century.
Edit: so my point is, sucking up the dollars will further exacerbate the non-liquidity problem. The Fed is stuck between the veritable "rock and hard place".
