I wish it'd hurry up. My pounds and euros are looking pretty measly in dollar terms. You guys should read Krugman's blog. He's one of the few with a tentative grasp on the macroeconomic phenomenon we're dealing with and he's pointing out that all this Hooverite angst about not being able to borrow has failed to cause a blip in Treasury interest rates or the dollar.
Anyway, the Fed can do quantitative easing and buy up all the debt the Treasury wants to sell. Massive amounts of credit were created from thin air in the past decade and are now being uncreated as the shadow system melts down. Le tthe Fed pump it back up to cover our deficit stimulus spending. You only have to worry about credit creation when the real economy overheats, which is exactly the opposite of our current problem.
