When does an interest rate path “look good”? Criteria for an appropriate future interest rate path

Svensson (2004) suggested that a monetary policy committee of a central bank (MPC) should “find an instrument-rate path such that projections of inflation and output gap ‘look good’.” Academic literature on monetary policy gives guidance as to what the words “look good” means. However, there is a need for a translation of the theoretical framework into concrete criteria when an MPC shall evaluate interest rate paths in practice. Six criteria for an appropri-ate interest rate path are presented. In the November 2005 Inflation Report, Norges Bank presented for the first time an optimal interest rate path including a fan chart illustrating the uncertainty of the forecast using these criteria. Ex-amples used in explaining the criteria are drawn from Norwegian experiences.
