The value of the Norwegian krone against the Deutsche mark was nearly halved between 1973 and 1987. We paid about 2 kroner for 1 mark in 1973 and close to 4 kroner in 1987. Since 1987, the krone exchange rate against the Deutsche mark has remained more or less unchanged. During this period, price inflation in Norway has been no higher than that in Germany. We cannot be sure how fast the inflation differential between Norway and other countries will translate into changes in nominal exchange rates in the future. Nevertheless, we must expect that any differences in the rate of inflation may be a key cause of changes in the nominal krone exchange rate over time. The Norwegian monetary authorities abandoned the devaluation approach in 1986. From 1986 to 1992 Norway had a fixed exchange rate with a defined central rate and fluctuation margins. This system was abandoned in 1992 following extensive speculation against the krone in connection with the turbulence in European exchange markets. After the krone was allowed to float on 10 December 1992, the guidelines for monetary policy were also revised. Monetary policy was still oriented towards the objective of krone exchange rate stability, but no specific central rate with fluctuation margins was stipulated. The krone depreciated slightly in 1992, but thereafter it remained relatively stable. Looking back at developments in the Norwegian foreign exchange market in the 1990s, no significant change really appears to have occurred in 1992. However, there was a marked shift in January 1997.
And this is despite the fact that we have encountered adverse shocks in that period, not least the slowdown in emerging market economies and renewed tensions in the euro area banking sector. So what accounts for this improved resilience of the euro area economy? Certainly the recovery cannot be explained by “endogenous” or underlying growth forces, which were unusually weak in its early phase. Nor can several of the “exogenous” factors that have supported previous euro area recoveries provide an answer. First, in the past euro area growth has been closely interdependent with world trade, with external demand playing a central role in supporting the recoveries after the dotcom crash and the Lehman bankruptcy. Since mid-2014, however, world trade has weakened considerably and last 1/6  BIS central bankers' speeches  year grew at the slowest pace since the financial crisis. Yet the correlation with euro area output has more or less broken down. Growth has accelerated even as world trade has fallen back. Second, though fiscal policy has stopped being a headwind – as it was during the 2011–13 period – it has not been much of a tailwind to the recovery either. With governments still undertaking a necessary process of balance sheet repair, fiscal policy between 2013 and 2015 was basically neutral and provided only a mildly positive contribution to growth last year. This contrasts with both the post-Lehman and post-dotcom recoveries where the fiscal stance was more expansionary.1 Third, the contribution of the supply side to the recovery has so far been limited.
