Reflection character of exchange rates and oil prices to Inflation: the case of Turkey

In this study which examines the relationship between exchange rate, crude oil prices and inflation, monthly data from 460 observations between 1980:01 and 2001:12 and between 2002:01 and 2018:04 were used. In the first and second sections of the three-part study, the conceptual framework for the pass through of exchange rate and oil prices to inflation, respectively, is given. The application part of the study consists of three parts; the determination of the stability between the variables in the first part, the Granger causality analysis applied by the Toda - Yamamoto method in the second part, and, lastly, the structural VAR analysis including the impulse-response and variance decomposition. According to the results, in the first sample period in which there is one-way causality from the nominal exchange rate to the consumer price (CPI), the pass through from nominal exchange rate to the CPI (0.65) is greater than the pass through from oil price to CPI (0.61). Moreover, in the second sample period in which there is one-way causality from the nominal exchange rate to the CPI and from the oil price to the CPI, the pass through from oil prices to the CPI (1.28) is greater than the pass through from nominal exchange rate to the CPI (0.16). Therefore, the effect of exchange rate on inflation in the first sample period and the effect of the oil prices on inflation in the second sample period are greater.
