The interest rate–inflation relationship under an inflation targeting regime: The case of Turkey

This paper examines the relationship between nominal interest rates and the expected inflation rate for the Turkish economy between 2002 and 2009, a period when the inflation-targeting regime was implemented as monetary policy. We use the test of cointegrating rank with a trend-break (a method introduced by Inoue, 1999) and we also apply exogeneity tests. Empirical findings indicate that monetary policy rates depend on inflationary expectations; long-term interest rates are affected by monetary policy; and the weak form of the Fisher effect is valid. This evidence implies that monetary policy has actually influenced the real long-term interest rates; the inflation targeting regime pursued by the Central Bank of Turkey is reliable; and hence realized inflation has remained close to its targeted level.
