The FT’s Martin Wolf is never knowingly optimistic, but his underlying argument that the problem is one of insolvency (as well as illiquidity) is, sadly, spot on, as is this:

Why then is the administration making what appears to be a blunder? It may be that it is hoping for the best. But it also seems it has set itself the wrong question. It has not asked what needs to be done to be sure of a solution. It has asked itself, instead, what is the best it can do given three arbitrary, self-imposed constraints: no nationalisation; no losses for bondholders; and no more money from Congress. Yet why does a new administration, confronting a huge crisis, not try to change the terms of debate? This timidity is depressing. Trying to make up for this mistake by imposing pettifogging conditions on assisted institutions is more likely to compound the error than to reduce it.
Assume that the problem is insolvency and the modest market value of US commercial banks (about $400bn) derives from government support (see charts). Assume, too, that it is impossible to raise large amounts of private capital today. Then there has to be recapitalisation in one of the two ways indicated above. Both have disadvantages: government recapitalisation is a bail-out of creditors and involves temporary state administration; debt-for-equity swaps would damage bond markets, insurance companies and pension funds. But the choice is inescapable.
