The impact of exchange rate on economic growth in Nigeria from 1981 to 2016 was studied. The researchers found that in the short term, factors like imports, trade openness, foreign direct investment (FDI), interest rate, and inflation affected economic growth. In the long term, trade openness, FDI, exchange rate, government expenditure, and interest rate influenced economic growth. Interestingly, the current year's exchange rate didn't directly impact economic growth in the short term, but its one-year lag did. Overall, effective exchange rate management, expansionary fiscal policy, and encouraging importation of capital goods are recommended for achieving economic growth in Nigeria.
