Banks And Capital Requirements

The global financial crisis produced an important agreement among regulators in 2010–11 to raise capital requirements for banks to protect them from insolvency in the event of another emergency. In this book, William R. Cline, a leading expert on the global financial system, employs sophisticated economic models to analyze whether these reforms, embodied in the Third Basel Accord, have gone far enough. He calculates how much higher bank capital reduces the risk of banking crises, providing a benefit to the economy. On the cost side, he estimates how much higher capital requirements raise the lending rate facing firms, reducing investment in plant and equipment and thus reducing output in the economy. Applying a plausible range of parameters, Cline arrives at estimates for the optimal level of equity capital relative to total bank assets. This study also challenges the recent "too much finance" literature, which holds that in advanced countries banking sectors are already too large and are curbing growth.

Over a decade has passed since the collapse of the U.S. investment bank, Lehman Brothers, marked the onset of the largest global economic crisis since the Great Depression. The crisis revealed major shortcomings in market discipline, regulation and supervision, and reopened important policy debates on financial regulation. Since the onset of the crisis, emphasis has been placed on better regulation of banking systems and on enhancing the tools available to supervisory agencies to oversee banks and intervene speedily in case of distress. Drawing on ten years of data and analysis, Global Financial Development Report 2019/2020 provides evidence on the regulatory remedies adopted to prevent future financial troubles, and sheds light on important policy concerns. To what extent are regulatory reforms 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. Global Financial Development Report 2019/2020 is the fifth in a World Bank series. The accompanying website tracks financial systems in more than 200 economies before, during, and after the global financial crisis (http://www.worldbank.org/en/publication/gfdr) and provides information on how banking systems are regulated and supervised around the world (http://www.worldbank.org/en/research/brief/BRSS).

The appropriate level of bank capital and, more generally, a bank’s capacity to absorb losses, has been at the core of the post-crisis policy debate. This paper contributes to the debate by focusing on how much capital would have been needed to avoid imposing losses on bank creditors or resorting to public recapitalizations of banks in past banking crises. The paper also looks at the welfare costs of tighter capital regulation by reviewing the evidence on its potential impact on bank credit and lending rates. Its findings broadly support the range of loss absorbency suggested by the Financial Stability Board (FSB) and the Basel Committee for systemically important banks.

This book is timely since the Basel Committee on Banking Supervision at the Bank for International Settlements is in the process of making major changes in the capital rules for banks. It is important that capital adequacy regulation helps to achieve financial stability in the most efficient way. Capital adequacy rules have become a key tool to protect financial institutions. The research contained within the book covers some key issues at stake in the capital requirements for insurance and securities firms. The contributors are among the leading scholars in financial economics and law. Their contributions analyze the use of subordinated debt, internal models, and rating agencies in addition to examining the effect on capital of reinsurance, securitization, credit derivatives, and similar instruments.
