Abstract:  The paper empirically investigates the degree of bank competition and intermediation efficiency in Ghana. The evidence obtained suggests a non-competitive market structure in the Ghanaian banking system, which hampers financial intermediation. The study also finds that Ghanaian banks are monopolistically competitive. It is argued that the structure, as well as the other markets characteristics, constitutes an indirect barrier to entry thereby shielding the large profits in the Ghanaian banking system. Further, it is argued that policies that encourage and stimulate greater consolidation in the financial sector would go a long way to enhance competition among banks and improve efficiency and profitability.
