ABSTRACT 

This research work is centred on the impact of exchange rate 

fluctuation on the Nigeria’s economic growth with special emphasis 

on purchasing power of the average Nigeria and the level of 

international trade transaction. Without exchange rate the exchange 

of goods and services among trading partners will be faced with a lot 

of problems, which may virtually narrow it down to trade by barter. 

This exchange also is used to determine the level of output growth of 

the country. Hence, the rate at which exchange fluctuates calls for a 

lot of attention. However, with already existing exchange rate 

policies, a constant exchange rate has not been attained. The rate by 

which exchange rate fluctuates brings about uncertainty in the trade 

transaction, and also the rate of naira has been unleashed and 

continues to depreciate. This has resulted to declines in standard of 

living of the population increase in costs of production (this is 

because most of the raw materials needed by industries are usually 

imported), which resulted in cost-push inflation. We made use of 

many tests, like the t-statistics table, f-statistic table and the chi-

square etc. When we found out real exchange rate has a positive 

effect on the GDP.
