Nice try; no cigar. That was my reaction to the attempt of the banking community to forestall additional regulation, by recommending “a suite of best practices to be embraced voluntarily”. It was also the reaction of the policymakers meeting in Washington over the weekend. More regulation is on its way. After frightening politicians and policymakers so badly, even the most optimistic banker must realise this. The question is whether the additional regulation will do any good.

In an interim report on “market best practices”, the Institute for International Finance, an association of bankers, offers devastating self-criticism.* Here then are some of the weaknesses it identifies: “deteriorating lending standards by certain originators of credit”; a “decline of underwriting standards”; an “excessive reliance on poorly understood, poorly performing and less than adequate ratings of structured products”; and “difficulties in identifying where exposures reside”. Would you buy a voluntary code from people who describe their own mistakes in this brutal manner? I thought not. There are two powerful additional reasons for not doing so.

Hardly a week goes by without the implosion of a hedge fund. Last week it was Carlyle Capital, with an astonishing $31 of debt for each dollar of equity. But we should not be surprised. These collapses are inherent in the hedge-fund model. It is even conceivable that this model will join securitised subprime mortgages on the scrap heap.

Getting away with producing adulterated milk is hard; getting away with an investment strategy that adds no value is not. That was the point made by John Kay, in a superb column last week (this page, March 11). With the “right” fee structure mediocre investment managers may become rich as they ensure that their investors cease to remain so.

Two distinguished academics, Dean Foster at the Wharton School of the University of Pennsylvania and Peyton Young of Oxford university and the Brookings Institution, explain the point beautifully*. They start by asking us to consider a rare event – that the stock market will fall by 20 per cent over the next 12 months, for example. They assume, too, that the options market prices this risk correctly, say at one in 10. An option costs $0.1 and pays out $1.
