Angola is analyzed under the empirical approach from the relationship between exchange rate and foreign direct investment (FDI) based on quarterly data from 2001-2024 acquired from the World Bank. After using unit root tests, Johansen co integration tests, and Granger causality tests, the results indicate that FDI is stationary at level and the exchange rate is stationary if it were first and second differenced. It shows that the co integration test holds true, indicating that there is one long run relationship between the FDI and the exchange rate, where FDI changes significantly (–0.24) to re-establish the long run equilibrium while the exchange rate changes weakly (0.002). With respect to FDI, Granger causality indicate that there is unidirectional short-run causality from exchange rate and international flows, implying that changes in the exchange rate can lead and impact foreign investment. In the long run, a 1% increase in the exchange rate would cause a 1.45% change in FDI, which suggests that movements in exchange rates are having a significant effect on foreign investment. It is recommended that policies are required to be implemented to stabilize the exchange rate as essential supports to retain FDI inflows to Angola.
