Keywords: financial deepening, sectoral growth, agricultural sector, manufacturing sector.


Purpose. The formal sector in Nigeria has experienced some transformation in the last 20 years. This has led to advancement and deepening of sector. Despite the progression achieved in financial sector, it has not yielded the desired impacts on the economy as experienced in other emerging economies. Hence, this research assessed the advantageous effects of financial deepening on sectoral advancement in Nigeria.

Methodology / approach. The research used the proxies of broad money (M2) to GDP ratio, and the ratio of credits to private sector to GDP for financial deepening. The data regarding time series were retrieved from Thomson Reuters DataStream and Augmented Dickey-Fuller unit root test and Johansen co integration approaches used for the long-oriented effects and Error Correction approach for short orientation estimation.

Results. The impact of financial deepening was positive and statistically significant in explaining agricultural growth, but the performance of the manufacturing sector was not significantly impacted in the reviewed period, hence government should make efforts to reduce the interest rate on loan bestowed to the private sector.

Originality / scientific novelty. The variables assortments have never been describing in the literature. Particularly, this study considers financial deepening as a significant determinant of sectoral development in the Nigerian context.

Practical value / implications. According to the results of the study, it is recommended to increase credits to the manufacturing sector through specialized banks and ensures the growth of the financial industry in terms of provision of quality financial instruments, sound financial and money markets, and transparent legislation for healthy competition in the industry for better sectoral performance.
