Therefore, this study analyzes the relationship of these variables, the extent of the influence of the US dollar exchange rate, inflation and export rates can influence changes in foreign exchange reserves. This research was conducted in Indonesia using secondary data for 30 years from 1988 to 2017. The analysis technique used was multiple linear regression. The results of this study indicate the effect of the US dollar exchange rate, inflation rate and simultaneous export of foreign exchange reserves of 0, 808, meaning that the influence of the three variables is 80.8 percent and the remaining 19, 2 percent is influenced by other factors not included in this study. This study produced a regression equation = 2, 529 + 0, 633 X1 0, 276 X2 + 0, 253 X3. The variable US dollar exchange rate shows the biggest influence that is equal to 63, 3 percent compared to the other two variables.
