Openness, financial structure, and bank risk: International evidence

Abstract

Using panel data from a large cross-country sample covering 97 countries over the period 1996–2017, we combine 2SLS procedure with system GMM estimation to study the relationship between openness, financial structure and bank risk. The main contribution of the paper is that we identified a new channel, i.e. the financial structure channel, through which financial openness reduces bank risk. In particular, we find that as financial openness increases, a country's financial system tends to be more market-based, and a more market-based financial system is associated with higher bank market power, better information sharing and more revenue diversification, all of which contribute to the reduction in bank risk. We also find that the effect of inflow restrictions on bank risk is more pronounced than that of outflow restrictions. These results highlight the importance of an appropriate design of a country's opening-up strategy to match the evolution of its financial structure to increase bank stability.
