The Dynamic Relationship between Bank Credit and Private Sector Development in Nigeria
Abstract
This study examined the dynamic relationship between bank credit and private sector development in Nigeria, with emphasis on the effect of sectoral credit allocation on private sector GDP growth. The private sector remains a critical driver of economic growth, employment generation, innovation, and industrial transformation; however, inadequate and poorly distributed credit has continued to constrain its performance in Nigeria. The study adopted an ex-post facto research design, which is suitable for analyzing historical relationships among variables using already existing data. Time- series secondary data were sourced from the Central Bank of Nigeria (CBN) Statistical Bulletin. The documentary method of data collection was employed, relying on annual data on sectoral credit allocation and private sector GDP growth over the study period. Data were analyzed using the Ordinary Least Squares (OLS) regression technique with a semi-log model specification. The findings revealed that agricultural credit had a positive but statistically insignificant effect on private sector GDP growth. Manufacturing credit also exerted an insignificant effect, while mining and quarrying credit showed no significant impact on private sector output growth. Similarly, real estate and construction credit did not significantly influence private sector GDP growth, and trade/general commerce credit equally had no statistically significant effect. However, despite the insignificance of the individual explanatory variables, the overall model was statistically significant, indicating that sectoral credit variables jointly had a significant effect on private sector GDP growth in Nigeria. The study concluded that private sector development in Nigeria is influenced more by the combined and complementary effects of sectoral credit allocation than by isolated lending to individual sectors. This implies that effective private sector growth depends on coordinated financing strategies, efficient credit utilization, and stronger inter-sectoral linkages. The study recommended that the Central Bank of Nigeria and deposit money banks should pursue balanced sectoral lending policies, while government should improve infrastructure, strengthen sector-specific financing frameworks, and enhance access to affordable credit for productive private sector activities.
