Abstract: The Central Bank of Sweden declares the use of the Svensson’s concept of inflation forecast targeting (IFT). It means that the repo rate decision making process depends on the central banks’ forecasts. The concept evolved from the strict IFT with the decision making algorithm called the ‘rule of thumb’ to the flexible IFT which later includes the optimal monetary policy plan. The aim of the article is to: (1) analyse the influence of the inflation rate and GDP growth rate on the repo rate decisions, (2) analyse the influence of the inflation rate and GDP growth rate forecasts (in two year horizon) on the repo rate decisions in Sweden in years 1999-2006. The main research question is as follows: did the Monetary Policy Commitee in Sweden in years 1999-2006 made the decisions on the repo rates on the basis of forecast-based instrument rules and the rule of the thumb algorithm. The analysis encompasses the repo rates decisions, CPI inflation rate, GDP growth rate, central paths of CPI inflation forecasts and central paths of GDP growth rate forecasts in the two years horizon published by The Central Bank of Sweden in years 1999-2006. The studies are based on the Taylor-type instrument rule and forecast-based Taylor-type instrument rule. The methodology used is multiple linear regression models. The Central Bank of Sweden in years 1999-2006 implemented direct inflation forecast targeting (DIFT) rule. The decision making algorithm was based on the CPI inflation forecasts and rule of the thumb algorithm. The exact rule of the thumb was as follow: if the inflation forecast, in the two year forecast’s horizon exceeded the inflation target by 1 p.p., then the central bank raised the repo rate by 0.4 p.p; if is below , then the central bank reduced the repo rate by 0.4 p.p. If the inflation forecast was equal to the inflation target, then the repo rate remained unchanged. The historical repo rates differ from the theoretical estimated rule of the thumb’s repo rates by +/-0.28 p.p.
