This study used daily time-series data from January 2018 to January 2021. In addition, the study applied the Autoregressive integrated moving average model (ARMA), the Exponential Generalized Autoregressive Conditional Heteroscedasticity (EGARCH), the Threshold Autoregressive Conditional Heteroscedasticity (TARCH), and Granger Causality analysis to measure the long-run effect of the volatilities of exchange rates to sectorial stock market indexes. The result of this study shows that the volatility of US Dollar exchange rate has strongly affected on the volatility of the banking sector index. The volatilities of EURO, Japanese Yen have a significant impact on the volatility of the Finance & Securities sector.
