This study investigates the impact of selected economic variables on Nigeria’s Gross Domestic Product (GDP) using a Vector Autoregressive (VAR) model. The variables considered include exchange rate, inflation rate, government expenditure, foreign direct investment, interest rate, and crude oil prices. The analysis utilizes time series data from 1986 to 2024, sourced from the Central Bank of Nigeria and World Bank databases. Stationarity tests confirm that most variables are integrated of order one, while VAR model estimation reveals significant dynamic relationships between the variables. The results indicate that exchange rate, government expenditure, and foreign direct investment have positive impacts on GDP, while inflation rate and interest rate exhibit negative effects. Crude oil prices show a mixed impact. The study’s findings have implications for monetary and fiscal policy formulation in Nigeria, highlighting the need for coordinated policy interventions to promote economic growth and stability.
