As interest rates fall, household and local government consumption and investment tend to pick up. Higher demand leads to higher output and employment. Wage growth may pick up. Higher wage growth combined with higher profit margins will result in higher inflation. Lower interest rates normally also lead to a depreciation of the krone. Imported goods then become more expensive and inflation accelerates. Expectations play a key role in price and wage formation, and they are influenced by the interest rate. Expectations concerning inflation and economic stability have considerable impact, not least in the foreign exchange market. Petroleum activity constitutes an important part of the Norwegian economy. Oil gives us an economic base that is not available to many other countries. At the same time, the extent of, and fluctuations in, petroleum activity pose a challenge to economic policy in Norway. In a long-term perspective, Norway’s petroleum wealth is to be distributed across generations. In the short term, the substantial capital revenues from the petroleum sector must be managed in such a way that they do not amplify cyclical fluctuations. The Government Petroleum Fund was established in 1990 with a view to safeguarding long-term considerations in the use of petroleum revenues. The idea behind the Petroleum Fund is that the cash flow from an increase in oil prices should accrue to the Fund and be invested abroad so that the  BIS Review 67/2004  1  increase in oil prices does not affect the wider budget.
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 and earnings to the Petroleum Fund and oil companies’ estimated cash surplus. Even though the current account surplus is increasing from 2003 to 2004 as a result of high oil prices, the adjusted basic balance is falling. In isolation, this is contributing to a decline in demand for the Norwegian krone. The decline is due to high import growth, which is reducing the current account surplus. In the Government’s budget proposal, the use of petroleum revenues remains virtually unchanged between 2004 and 2005. In spite of this, the krone exchange rate has appreciated recently. This reflects short-term capital inflows and may indicate that foreign exchange market operators expect that the use of petroleum revenues will increase in the years ahead. Themes in foreign exchange markets shift. In periods, investor focus on stock returns feeds through to exchange rate movements. During periods of political and economic unrest, investors may choose individual currencies as a safe haven - often the Swiss franc. In the autumn of 2002, the Norwegian krone was probably also perceived as a safe haven. In addition oil prices rose as a result of the uncertainty associated with the war in Iraq. Fluctuations between major currencies also affect the krone exchange rate. In recent weeks, investors have withdrawn from the US dollar and a number of currencies have appreciated.
