Abstract :This study investigates the impact of exchange rate shocks on pricing and whether the values normalise after the shock ends. Accordingly, the study tests the existence of inflation hysteresis. Goods and services sector inflation figures are used in the evaluation, and the data for the Turkish sample between February 2003 and December 2022 are analysed. The data are analysed by subjecting them to Traditional Fourier and Fractional Frequency Fourier tests. The methods used in the study minimise the margin of error as they include sine and cosine values as well as structural breaks in the analysis and are considered to be one of the most up-to-date analysis methods. According to the study’s findings, the increase in inflation rates in Türkiye does not show a permanent feature after appropriate policy adjustments.
