Those Marxist-Leninists at the Financial Times:

It is important to realise that this liquidity crisis is the result of a co-ordination failure: bank A does not want to lend to bank B, not necessarily because it fears insolvency of bank B but because it fears other banks will not lend to bank B, thereby creating insolvency of bank B out of the blue. Thus bank lending comes to a standstill because banks expect bank lending to come to a standstill.

How to get out of this bad equilibrium? There is only one way. The governments of the big countries (US, UK, the eurozone, possibly Japan) must take over their banking systems (or at least the significant banks). Governments are the only institutions that can solve the co-ordination failure at the heart of the liquidity crisis. They can do this because once the banks are in the hands of the state, they can be ordered to trust each other and to lend to each other. The faster governments take these steps, the better.
