It may be useful to distinguish between three channels through which monetary policy operates: •  The demand channel  •  The exchange rate channel  •  The expectations channel  The effect on inflation of changes in interest rates occurs with a lag and may vary in intensity. In the time it takes for a change in interest rates to feed through, other factors will also have an impact resulting in changes in inflation and output. We cannot assume that the various relationships are entirely stable. As interest rates fall, household and municipal consumption and investment will tend to accelerate. This is because they have more money left over after servicing their debt and because borrowing is less expensive. Corporate finances are strengthened and investment may become more attractive. 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. The effect of interest rate changes may be amplified because the interest rate also affects the krone exchange rate. When interest rates are lower, more people will borrow money and fewer will invest in NOK. Lower interest rates will thus normally lead to a depreciation of the krone. Imported goods will then become more expensive and inflation will accelerate. A weaker krone also boosts exports and improves profitability in Norwegian business and industry. The effect on the exchange rate of a change in interest rates will vary as themes and sentiments shift in the foreign exchange market.
We know this is what the people in Europe, and in Germany, aspire to. 2  BIS central bankers’ speeches
