This study examined the effect of external debt burden on the growth of Nigeria economy. Time series data was sourced from Central Bank of Nigeria Statistical Bulletin from 1986-2019. Nigeria real gross domestic was proxied for dependent variable while debt servicing; external debt stock, debt overhang, debt sustainability and crowd-out effect of external debt were proxies for independent variables. The study employed multiple regression models to estimate the relationship that exists between external debt burden indicators and Nigeria economic growth. Ordinary Least Square (OLS), Augmented Dickey Fuller Test, Johansen Co-integration test, normalized co-integrating equations, parsimonious vector error correction model and pairwise causality tests were used to conduct the investigations and analysis. The study findings revealed that 72 percent of the variations in Nigeria gross domestic products can be explained by the changes in external debt burden indicators. The results indicated a negative coefficient with external debt stock and debt overhang while a positive coefficient with debt sustainability, debt servicing and crowd out effect of external debt on Nigeria gross domestic products. From the findings, the study concludes that external debt burdens significantly affect growth of Nigeria economy. We recommend that the fund borrowed should be effectively managed, the federal government should laydown guidelines in terms of defining the purpose, duration, moratorium requirements and commitments, negotiation among others including conditions for external debt loans. Government should initiate and develop policies that will address the fundamental causes of external debt.
