Result reveals that there is a long run relationship existing between financial deepening series and economic growth nexus in Nigeria, this result creates a headway for the estimation of error correction. Result from the analysis reveals that error correctional analysis proves that the variable converges to long run equilibrium. However, it will take the shock emanating from the convergence one year, seven months and four days to return the error caused by the convergence to equilibrium. it was concluded that financial deepening series and economic growth had a longing relationship in Nigeria Therefore a macroeconomic variable as contained in the financial depth called financial development has been seen to have a serious positive implication on economic activities in Nigeria.
