It will actually divert money to the Treasury from commercial lending. Naked Capitalism has more, concluding:
When Paulson dumps out his 700 billion in treasuries it’s going to be at the short end. That will drive up rates for short-term treasuries. This will obviously draw even *more* deposits into the treasury MMs. That means even less in the commercial MMs and thus less working credit, the eventual commercial MM product. Hence Paulson’s billions remove working capital by competing for the deposits that could get used to make working capital loans. That 700 billion is going to go to fairly long-term mortgage securities. So Paulson’s billions divert credit from working capital to long-term mortgages – from where it’s most needed to where it’s most wasted.
Even if the giveaway adequately props up the banks, which I doubt, they still can’t make working capital loans, because the raw material they used (commercial MM deposits) will be desperately short.
I think it’s very telling that in two days of hearings and two weeks of discussion we have yet to see *any* detailed mechanism for how Paulson’s plan will increase the supply of, say, inventory loans. It’s not that every economist in the world is an idiot, it’s just not going to help. I think people have fallen into the fallacy that if it costs a lot it must be valuable. Paulson’s plan falls into the category of very expensive way to hurt ourselves.
