Financial reforms and credit growth in Nigeria: empirical insights from ARDL and ECM techniques

In the last 37 years, Nigeria has undergone several stages of financial reforms with different impacts on the economy. This paper analyses the impact of these financial reforms on credit growth in Nigeria using annual data from 1980 to 2016. The research work hinges on the theoretical underpinning of McKinnon-Shaw hypothesis on the relevance of financial reforms in a lagging economy. Analysing the data with autoregressive distributed lag error correction representation and bounds testing techniques, we find evidence supporting this hypothesis, and specifically that at higher real interest rates there is increased financial intermediation evidenced by credit growth. Other findings are that in the long-run, financial system deposits, inflation rate and per capita GDP are strong asymmetrical predictors of credit growth and real interest rates (the financial reform indicator), while the short-run relationships are indicator-specific. We further show that a long-run cointegration relationship exists between domestic credit and other covariates and likewise between the real interest rate and its regressors.
