In this study using an approach, this study uses time series data from 1993 to 2023, time series data obtained from the source of the Central Statistics Agency of West Sumatra Province. This study uses several test models including descriptive statistical tests, normality tests, autocorrelation, heteroscedasticity, multicollinearity, multiple linear regression, R² test, t test, and f test. The data obtained were processed using SPSS statistics version 26. The test carried out on the t test has a positive influence on the exchange rate t_calculated (4.577) > t_table (2.048), significant 0.000 <0.05. The test conducted on (X2) found that the interest rate had a negative effect on the exchange rate t_count (4.561) > t_table (2.048), with a significance of 0.000 < 0.05. The results of the f test conducted showed that inflation and interest rates equally affected the interest rate with a t_count value of 11.153 > t_table 3.33, and a significance of 0.00 < 0.005. The test conducted simultaneously using R square 0.443 / 44.3%, the test results together affected the exchange rate by 44.3% which means weak distribution, for 55.7% of 44.3% outside the variables studied.
