Trade–Finance Nexus: The Centrality of the Quality of Institutions in Sub-Saharan African Leading Economies

Abstract

The study examines the interaction effect of trade and institutional quality on financial sector development in 20 leading economies in sub-Saharan Africa selected based on 2018 GDP per capita ranking (top 20 richest economies by GDP per capita released by the IMF) over the period 2005–2020. Using system-generalised method of moments estimation, the results indicate that the effect of the interaction term of trade and regulatory quality on financial development is positive and significant. Further findings show unidirectional causality running from the interaction term to financial development, implying that the likelihood of trade enhancing financial development depends on the soundness of the regulatory framework. It is confirmed that the magnitude and direction of the effect of trade on financial development are sensitive to the quality of institutions. Therefore, the poor quality of regulations on business activities and financial services could undermine the salutary impact of trade on financial development. It is suggested that creating a conducive regulatory environment to improve the level of financial development is crucial for mitigating the potential impact of the weak institutional quality risks. This remains a significant prerequisite for having a competitive business environment, thereby stimulating the role of trade in the process of financial development.
