Evaluation of Long Run Relationship between Financial Development and Economic Performance in Nigeria

Abstract:
This study aimed to assess the long-term
interconnections between Nigeria's economy and financial development indicators,
adhering to standards, by analysing the existing relationships between these
indicators and Nigeria's economic growth based on current data. Secondary data
were obtained from the Central Bank of Nigeria's Statistical Bulletin and the
World Bank's Financial Development Indicators Database covering the period from
1994 to 2023. The results of the Auto Regressive Distributed Lag Bound Test
conducted on a long-term basis revealed that credit extended to the private
sector and the number of active bank accounts per 100,000 adult population were
important predictors of Nigeria's gross domestic product in the long run.
Nonetheless, the lending-deposit spread, and asset quality ratio did not pass
the significance test. Thus, the study determined that of the four explanatory
variables analysed, only two—credits to the private sector and the number of
bank accounts per 100,000 adults—are significantly relevant in forecasting Nigeria's
gross domestic product in the long term, whereas lending-deposit spread, and
asset quality ratio are not. Thus, the research advised that the Central Bank
of Nigeria should increase the statutory maximum loan-to-deposit ratios for
operating banks to facilitate more lending to clients, which, via expected
multiplier effects, would accelerate economic growth.
