Study of the Influence of the Banking Sector Development on the Inflows of Foreign Investment in Nigeria and Ghana

The level of bank development has a determinant effect on the growth potentials of a developing economy. In response, this study examined the impact of banking sector development on foreign investment inflows in the West African countries of Nigeria and Ghana. The study relied on secondary data for analysis and made use of multiple regression technique. However, to ensure the authenticity of our result, Augmented Dickey-Fuller unit root test and Johansen Cointegration techniques were respectively employed to test for the presence unit root and long-run equilibrium relationship in the exogenous variables. Additionally, causal relationships were tested with Granger Causality. It was revealed that banking sector development has a significant influence on foreign investment inflows in the two West African countries. Specifically, domestic credit to private sector and bank deposit rate has significant influence on foreign investment inflows in both countries. Whereas domestic credit to private sector is directly related to the dependent variable in Ghana, it is related inversely in Nigeria. It was also discovered that bank lending rate is significantly and positively related to foreign investment in Ghana. Intermediation efficiency and profitability of banks should be improved by enhancing the capital structure and adopting the appropriate lending rate especially in Nigeria as measures to attract more inflows of foreign investment in both countries.
