Drawing on 10 years of data and analysis, Global Financial Development Report 2019/2020 provides evidence on the regulatory remedies adopted to prevent future financial troubles, and it sheds light on important policy concerns. To what extent are regulatory reforms that are designed with high-income countries in mind appropriate for developing countries? What has been the impact of reforms on market discipline and bank capital? How should countries balance the political and social demands for a safety net for users of the financial system with potentially severe moral-hazard consequences? Are higher capital requirements damaging to the flow of credit? How should capital regulation be designed to improve stability and access? The report provides a synthesis of what we know, as well as areas where more evidence is still needed.
