Either way, the government's screwed. If you tell the public everything, you risk panic and further depression of an already depressed economy. Disagreements on economic theory aside, I think most will agree that the level of "confidence" amongst the People has a profound impact on the functioning of the economy. So, there is the incentive to remain silent, or at least ambiguous.
OTOH, if you withhold all information and something happens, public confidence is also shattered: "How could they not see this coming?"
Finally, releasing partial information is, imo, a game by which the government can have plausible deniability about "being out of the loop", whilest maintaining some facade of safety. Or so the reasoning would go. Unfortunately for people paying attention, it is likely more disquieting to be told, "Something's gonna happen, but we're not going to tell you what."
I don't see anyway to release all/some/no information on this that is going to make anything much better. :-(
