If we add to the foregoing ingredients a strong increase in banking competition, both among deposit institutions and between these and other less regulated non-bank competitors, the pressure to increase the risk profile in order to maintain past profit levels simply heightens banks' incentives to take on more risk in upturns. Having commented on the problems of excessive credit growth and how a more conservative monetary policy can mitigate them, I would like to move forward to the second part of my speech, and concentrate on the resilience of the banking system and the role of supervisors. We should acknowledge that the resilience of the financial system in general, and of credit institutions in particular, plays a key role in softening cyclical downturns. Evident in this crisis has been the notable weakness with which many banks have faced the downswing. To increase their resilience, banking regulation policy can perform a pivotal function by curbing  2  BIS Review 149/2008  the countercyclical behaviour of capital, so that it protects banks and prepares them for the crisis. And to discuss this, I am bound in this second part of my speech to refer to Rojo (the Spanish for red, and “Rot” in German). Again, this is not only a type of wine but the name of the former governor of the Bank of Spain entrusted with steering and successfully ensuring the Spanish economy’s entry into the euro area.
It was also Rojo who, in the final stage of his mandate as governor of the Bank of Spain, designed and put into practice the prudential regulatory mechanism of dynamic provisioning. This has contributed to reinforcing the stability of the Spanish banking system and today commands wide recognition; but, when initially launched, it aroused understandable rejection by Spanish banks and was met with indifference on the part of the international community of banking regulators and supervisors. Let me give you the background to this prudential and countercyclical regulatory mechanism. The origins of Spanish dynamic provisioning must be sought in credit developments in the late 1990s. Having emerged from the 1993 recession, the worst for 40 years in Spain, the economy, and much more intensely so bank lending, began to expand at an increasingly brisk pace. The Bank of Spain was led to introduce dynamic provisioning, which came into force in mid2000, by a combination of factors. These included most notably: the mix of strong credit growth, with the dangers this entailed for the stability of the financial system; heightened competition, which acted to exacerbate these risks given that credit institutions applied increasingly lower risk premia to maintain their market share; the deterioration in the level of loan loss provisions and their extremely high correlation with current default rates; and, finally, the Bank of Spain’s past supervisory experience.
