The number of coronavirus cases, the BIST-30 Index and the effective sales figures for the dollar were analyzed using daily data for the period of 11 March 2020-11 March 2021. The aim of the study is to determine whether there is a causal relationship between the variables. Based on the prediction model obtained, the Granger Causality test was used to determine the causality relationship between the variables. According to the analysis findings, a bidirectional causality relationship was found between the growth rate in the dollar exchange rate and the growth rate in the BIST-30 index. In addition, while the growth rate of the dollar is the granger cause of the number of coronavirus cases; A change in the number of coronavirus cases is not a granger cause of dollar rate growth.
