Cochrane has a good analysis of the current problem, though I think he may underestimate the number of healthy banks out there. I say "may" because neither he nor I really know. There's good data as of June 30, but no official statistics that reflect the dismal summer.
He is very negative on the bailout bill. I was never a fan of it, but I'm not quite as skeptical, perhaps because I can envision it helping the banks that need it the most. Perhaps I'm being overly optimistic.
