Risk and the new financial order | Surviving the markets | Economist.com

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.

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.

Because this crisis taps so deeply into the newly devised structures of finance, anyone who says the worst is definitely over is either a fool or someone with a position to protect. As risk has become bewilderingly dispersed, so too has information. Nobody yet knows who will bear what losses from mortgages—because nobody can be sure what those loans are really worth. Nobody knows if tighter lending standards will oblige borrowers to raise more capital, triggering more sales in stockmarkets and more pain. Nobody knows how messy the inevitable bankruptcies will turn out to be. What markets need now is time to piece that information back together. Time before the next wave strikes.
