There isn't a problem of perceptions or expectations. There's a problem.

Last week’s co-ordinated liquidity action by five central banks taught us that this is not the case. The idea was that a co-ordinated response would reassure the markets, but it had the opposite effect. It turned out that market participants are not infinitely stupid. They know by now that this is not a liquidity crisis at its core. If it had been, it would be over by now.

It is a fully fledged solvency crisis that has arisen because two giant and interlinked bubbles burst simultaneously – one in property, one in credit – leaving banks and investors on the brink of bankruptcy, some hanging on by their fingertips. Yet there is nothing the central banks are offering at this stage to alleviate a solvency crisis.
