the imf is broke if a couple of eastern european countries default. besides, it is only a collection of credits for iou's established by a bunch of countries. it will no doubt be sucking at the money trough again shortly.
and the b. i. s. is too narrow in scope and still just a point for collection and disbursment of iou's. assets in tradeable securities? there are very few tradeable securities that aren't in the tank now.
