Calculated rates

Nominal effective krone exchange rate calculated on the basis of NOK-exchange rates against the currencies of Norway's 25 main trading partners (geometric average using the  OECD's trade weights (PDF) )The index is set at 1990 = 100. A rising index value denotes a depreciating krone exchange rate. See a closer description (PDF). 

 

I44 - Import-weighted krone exchange rate

The index is a geometric average of 44 exchange rates. The weights are calculated on the basis of imports from 44 countries, covering 97 per cent of total imports. The weights are chain-linked and based on average import shares. The index is set at 1995 = 100. A rising index value denotes a depreciating krone exchange rate. The index is calculated using the same methodology as with the TWI (closer description (PDF)).

The index is also described in more detail in a box in Inflation Report 1999/1.
