From a medium-term perspective, and even when conditions are established that will free up the flow of credit from the banking sector to the  4  BIS Review 52/2009  real economy, it cannot be expected that rates of expansion will rise again to the heights of recent years. The de-leveraging process underway in the banking sector, and in the economy in general, is not a passing fad, but rather a means of achieving lower and more sustainable debt positions. One way of making up for the lower rates of credit expansion, and thus countering the foreseeable narrowing of net interest margins, would be to diversify banking activity into new business segments. In principle, diversification is a positive thing, but it must be undertaken with caution. Experience shows that both in Spain and internationally, only on limited occasions can an institution's sound knowledge of its core business be directly transferred to activities that lie further afield. Accordingly, those in charge of institutions should show prudence and avoid what can be termed contrived diversification processes and carefully assess their entry into unfamiliar market segments in which they lack experience. Second, in the short term bad debts will keep rising and so the pressure on loan loss provisions will continue to be high. It is true that the reduction in interest rates will bring relief for households and firms and help to limit the impact of the rise in bad debts, but the contractionary phase of the cycle will foreseeably last some quarters.
The recent forecasts by various international organisations indicate that, in fact, we are in a very serious worldwide recession, from which neither the euro area nor the Spanish economy have been spared. In general, according to the available forecasts for developed countries, the problems will be acute in 2009, although it is expected that at some point during 2010, taking into account the current high uncertainty any forecasting exercise entails, an incipient recovery may become discernible. The Spanish banking system, as is inevitable when faced with a global financial crisis, has not been immune. Nevertheless, the impact has been no less than in other banking systems, where public authorities have had to take control of very large institutions, as I have said. This better relative performance can be explained by at least two factors. Firstly, the business model of Spanish credit institutions is based on traditional retail banking and is founded on long-term relationships with customers and creditors. This type of banking model has enabled credit institutions to acquire in-depth knowledge of their customers, reducing the perverse effects linked to asymmetrical information present in any banking business model. Similarly, since it does not use asset securitisation as a risk transfer mechanism but only as a means of obtaining liquidity, the origination and acquisition of complex structured products has been avoided, which have proved to be substantially opaque and the cause of hefty losses for many institutions in various countries.
