This study investigates the macroeconomic determinants of foreign direct investment (FDI), focusing on the
effects of interest rates, inflation, and gross domestic product (GDP) on FDI inflows. Using a log-linear Ordinary Least
Squares (OLS) regression model and a dataset comprising 33 annual observations, we examine the relationship between
the natural logarithms of FDI, interest rates, inflation, and GDP. The results indicate that inflation has a statistically
significant and negative impact on FDI, suggesting that rising inflation discourages investment inflows. Interest rates
exhibit a positive and marginally significant effect on FDI, while GDP does not show a statistically meaningful relationship.
Variance Inflation Factor (VIF) and Belsley-Kuh-Welsch diagnostics suggest moderate multicollinearity, particularly
involving GDP, but not at a level requiring model revision. These findings highlight the sensitivity of FDI to macroeconomic
stability, especially inflation, and underscore the importance of maintaining a favorable investment climate
