Monetary Policy and Development of Nigerian Economy

Abstract

- This study examined monetary policy and development of the Nigerian economy over the period 2001 – 2025. The study was motivated by the need to determine how major monetary policy instruments influence human development outcomes in Nigeria. An ex-post facto research design was adopted, using annual secondary data on Human Development Index (HDI), Monetary Policy Rate (MPR), Treasury Bill Volume (TBVOL), Money Supply (M2), and Cash Reserve Ratio (CRR). Data were obtained from Central Bank of Nigeria publications, the National Bureau of Statistics, and other sources. Ordinary Least Squares regression was employed using EViews 9.0. Descriptive statistics, correlation analysis, Variance Inflation Factor, diagnostic tests, Group Unit Root Test, and Johansen Cointegration Test were also conducted. The regression results showed that the monetary policy variables jointly had a statistically significant effect on HDI, with an R-squared value of 0.998254 and an F-statistic probability value of 0.0000. MPR had a positive and statistically significant effect on HDI, with a coefficient of 0.033857 and probability value of 0.0000. TBVOL exerted a negative and statistically significant effect, with a coefficient of -0.052537 and probability value of 0.0363. M2 had a negative but statistically insignificant effect, with a coefficient of - 0.035621 and probability value of 0.0905. CRR had a negative and statistically significant effect on HDI, with a coefficient of -0.078482 and probability value of 0.0000. The findings indicate that monetary policy instruments influence economic development through different transmission channels, including interest rates, liquidity, credit availability, and financial intermediation. The study concludes that monetary policy should be carefully designed to support macroeconomic stability while promoting productive investment, credit access, employment, and improvements in human welfare. The study recommends balanced MPR management, improved Treasury bill operations, productive allocation of monetary expansion, and carefully calibrated CRR policies to strengthen monetary policy transmission, support productive activities, and foster sustainable economic development in Nigeria. The study contributes to Nigerian literature by demonstrating that monetary instruments can produce different outcomes, underscoring coordinated policy implementation and effective transmission mechanisms.
