In this context, an exact definition of the responsibilities of the SNB and FINMA is of central importance for optimal macroprudential supervision and regulation. The revised Memorandum of Understanding between the SNB and FINMA is an important step in this direction. Secondly, to ensure that the institutions involved can optimally carry out the roles assigned to them, it is also important to give them the right tools. In concrete terms, this means that the SNB would, for example, need to have more extensive information about the stability of financial institutions – regarding their risk exposure, interdependences, etc. – or it would require specific instruments enabling it to take the right decisions when implementing macroprudential policy. Thirdly, the crisis made it clear that closer international cooperation between regulatory authorities is vital. Functioning international coordination mechanisms are required to counter future crises earlier and more effectively. International cooperation is the only way to check undesirable developments on the globalised financial markets. BIS Review 121/2010  5  Conclusion Ladies and gentlemen, the stable economic growth and low inflation of the last two decades could not prevent the emergence of vast imbalances in the global financial system, as the financial and economic crisis clearly showed. Such massive economic shocks are bound to have an impact on how central banks work. Nevertheless, ensuring price stability remains our top priority. The crisis made it evident that central banks have an effective set of instruments that can be used to mitigate the negative impact of financial crises.
Developments in other countries are just as important for the krone as developments in the Norwegian economy. Capital flows freely and flows can change rapidly. This can spill over to exchange rates and interest rates as well as output and employment. There is a cost involved for businesses in hedging against fluctuations in the krone. A krone that is stable - but too strong - also entails social costs in the form of low activity. Likewise, a krone that is stable - but too weak - is a source of high inflation. Norway is running a current account surplus as a result of sizeable oil and gas exports. Owing to high oil prices, the current account surplus is rising this year. An increase in the current account surplus will normally result in higher net demand for the domestic currency. In Norway, however, the additional foreign exchange revenues that accrue to the Norwegian state as a result of high oil prices will be invested in foreign securities through the Government Petroleum Fund. As a result, they will not have a direct impact on the balance in the Norwegian foreign exchange market. Oil companies hold a large share of their financial capital in foreign currency, and higher revenues in these companies therefore results in an increase in capital outflows. The effects of changes in the current account on net demand for the Norwegian krone can be illustrated by adjusting the basic balance for transfers to the Petroleum Fund and oil companies’ estimated cash surplus.
