From a financial management point of view, large investors may give priority to companies with a low risk profile, in order to bring back their own asset portfolios to levels of volatility matching their requirements. Therefore listed companies will have an incentive to adjust their risk profile and avoid more hazardous –which may also be more innovative– investment projects. Therefore, “entrepeneurship” may be curbed and the growth potential may be influenced adversely. Another impact of volatility on financial management is related to recourse to hedging, namely derivative products. As I mentioned earlier, derivatives are a driving force behind mature financial markets, and their strong development in the last two decades is merely consequence of the benefits they have generated. More precisely, derivatives and related financial innovations have enabled companies to transfer the impact of interest rate and currency fluctuations to financial institutions or investors that were ready to manage it, whereby facilitating international trade or project financing. Meanwhile, the pricing of derivatives is closely linked to volatility. As volatility is indeed difficult to predict, market practitioners have developed models, which are constantly being refined. Over time, market participants, –especially banks,– have become more competent in managing risk, while being left that residual risks which are more complex and harder to control. These consequences would not be a major concern, if the episodes of excessive volatility were only accidental. Peaks of volatility clearly reflect macroeconomic imbalances, as soon as market participants take into account the relevant information.

•  Fifthly, central bank independence is of the essence. It is an integral part of the acquis communautaire, which is laid down not only in national legislation but above all in the  8  BIS Review 71/2002  Maastricht Treaty. The effective implementation of the acquis communautaire is not only a legal prerequisite for accession to the EU. It also implies the effective transformation of accession countries’ economic framework, which should facilitate their integration into the EU and, later, the euro area. In this context, it should be ensured that there is no discrepancy between the central banks’ formal status in the legislation and the implementation of that legislation. It is of utmost importance that all present and future Member States respect this economic and institutional ground rule of the European framework. •  Sixthly, let us not forget the present and future contribution of Central and Eastern European countries to the economic prosperity of Europe at large. It seems that this contribution might be sometimes underestimated, while the relative influence of the US economy, for instance, might be sometimes overestimated. In fact, transition economies, as a whole, are as important as the US in terms of external demand addressed to the euro area: they both enjoy the same share, i.e. 13% of our exports. And, during the last two years, transition economies contributed for two-thirds to the overall growth of our total external demand, while the US contributed for less than 0.1%.
