There's going bust and going bust. Fannie, Freddie and FDIC are not really going to be insolvent, ever...because Uncle Sam will get his checkbook out and solve the problem. Remember the Savings and Loan crisis from the Carter era? You might not, since you this the Bush economy and the Carter economy are so different. We tax payers footed the bill on that one, and if my least favorite Uncle says so, we'll do it again.

Bernanke is trying to reassure the markets in the hopes that a white knight(s) will rescue Fannie and Freddie and the government won't have to do so. Probably a vain hope, but its worth a shot. See #10 from BA's original post.
