Think the worst is over? The Economist thinks it has only begun:
The retreat to a new level of risk was never going to be orderly or free of casualties. Neither should it be. Bankers and investors need to suffer precisely because the methods of modern finance have been found wanting. It sounds Darwinian, but the brutal demonstration that you pay for your sins is what leads the system to evolve. Markets learn from their mistakes. Only fear will spur investors to price risks better and get them to put more effort into monitoring their counterparties.I personally think that central banks should step in... by tightening monetary policy over the long term. This will increase personal savings which will, in turn, become the basis for further economic activity. If cash is valuable, and if the central banks keep it valuable (by keeping inflation non-existent), it provides a secure footing for future economic growth. It'll be far better than debt.
If these lessons are to sink in, central bankers must stand back—as, by and large, they have done. Every intervention now will be taken as a sign of what the regulators will do next time. If they bail out banks that have mispriced risk, the mispricing will continue. And when the central banks do step in, it should not be to save the financiers. The cost of intervention is warranted only to save the rest of the economy from the financiers' folly. By that test, central banks were right to lend money to the banks in recent days, because it ensured that a liquidity crisis did not become a solvency crisis. They may yet have to take over a failed bank, though only if that is needed to stop a run. It is still far too soon to cut interest rates.
