Tác động của khủng hoảng tài chính đến đa dạng hóa thu nhập của ngân hàng

Abstract

Using data of 3,695 commercial banks from 142 countries over the period 2002- 2021, our OLS estimates with multiple fixed effects and two-stage least squares approach provide evidence that banking crisis significantly increases the level of bank income diversification, especially large banks. As the business model of small banks focuses on traditional lending activities, income diversification of small banks is not affected by banking crisis. Currency crisis and sovereign debt crisis are not significant drivers of bank income diversification. Tightening regulations on bank activity restrictions and capital stringency helps to cushion the impact of financial crises on bank income diversification. Our findings provide a comprehensive view of the impact of financial crisis on bank income diversification as well as the roles of some bank regulations in times of financial crisis. Some policy implications are also provided for policymakers to implement appropriate policies that reduce bank risktaking during periods of financial crisis.
