The main aim of the study is to investigate the impact of inflation targeting (IT) strategy in Turkey during 2002-2022, which was adopted in a three-year period of 2002-2004, on macroeconomic performance (actual inflation, exchange and interest rates) and economic growth of Turkey (in terms of the real GDP). The econometric and empirical investigation of this research focusing on the impact of inflation targeting on the selected macroeconomic variables were carried out by the linear squares method (LSM) regression taking the data of the period after implementation of the monetary policy. At this, the independent variable of inflation targeting was estimated against each chosen macroeconomic variable separately in four different models to catch its linear impact on the changes of these variables over the period after implementation of the strategy. The empirical outcomes demonstrated that inflation targeting monetary policy is strong enough to impact the macroeconomic performance of Turkey in terms of reducing inflation rates, boosting economy by pushing real GDP to grow, stabilize exchange rates and lower the nominal interest rates on deposits.
