In connection with the expansionary cycle of the world economy, and also with the depreciated dollar, prices of copper, oil and derivatives – especially gasoline – are picking up again. The rise in commodities’ prices has now spread to foods. For the year 2008, projections from Consensus Forecast foresee global growth similar to that of 2007 but with a rebound in the U.S. and a slight deceleration in the euro zone and in emerging economies, influenced by the process of monetary normalization implemented to keep inflation under control. Such a favorable global scenario may continue longer, but it can also deteriorate if a number of latent risks materialize. The most important ones facing the world economy are: (1) a deeper deceleration in the U.S. as a result of a stronger adjustment in the housing sector that ends up shocking the rest of the economy and the world; (2) an acceleration of inflation because of supply-side shocks in a global economy with little output gaps, which generates a  2  BIS Review 87/2007  sudden and large increase in the monetary policy rates of industrial economies, especially the U.S. and the euro zone; (3) an unforeseen sharp increase in risk premiums and a liquidity shortage affecting asset prices and world activity as a result of an unexpected increase in inflation in the developed world or a shock in financial markets, at a time when risk premiums are in unusually low levels.
At the presentation of the last report on financial stability, we expressed our conviction that the financial system needs to be made more resilient to possible shocks. This is all the more valid if we consider the hundreds of billions of taxpayers’ money that had to be spent worldwide on stabilising the financial system over the past few months. The focus is on the need for improvement in the “shock absorbers”: capital and liquidity. The crisis has shown that the current regulation in these areas is no longer sufficient in the case of the big banks. Their level of capital is inadequate when set in relation to their risks. In the area of liquidity, events have occurred that were not taken into account in any of the big banks’ scenarios. The reform of the capital adequacy regulation for big banks, drawn up by the SFBC with the support of the SNB, represents an important step in the right direction – for the area of capital. It specifies an increase in risk-weighted capital together with the introduction of a leverage ratio. The leverage ratio is a supplementary instrument and does not call into question the principle of risk-sensitivity with regard to the capital regulation. An essential constituent of the reform are countercyclical mechanisms whereby, in good times, banks are required to considerably exceed the minimum requirements for capital and the leverage ratio. This ensures that a buffer is created to absorb losses during crises.
