Deposit Insurance Around The World

Explicit deposit insurance (DI) is widely held to be a crucial element of modern financial safety nets. This book draws on an original cross-country dataset on DI systems and design features to examine the impact of DI on banking behavior and assess the policy complications that emerge in developing countries.

Explicit deposit insurance has been spreading rapidly in recent years, even to countries with low levels of financial and institutional development. Economic theory indicates that deposit-insurance design features interact--for good or ill--with country-specific elements of the financial and governmental contracting environment. This paper documents the extent of cross-country differences in deposit-insurance design and reviews empirical evidence on how particular design features affect private market discipline, banking stability, financial development, and the effectiveness of crisis resolution. This evidence challenges the wisdom of encouraging countries to adopt explicit deposit insurance without first stopping to assess and remedy weaknesses in their informational and supervisory environments.

This paper provides a comprehensive, global database of deposit insurance arrangements as of 2013. We extend our earlier dataset by including recent adopters of deposit insurance and information on the use of government guarantees on banks’ assets and liabilities, including during the recent global financial crisis. We also create a Safety Net Index capturing the generosity of the deposit insurance scheme and government guarantees on banks’ balance sheets. The data show that deposit insurance has become more widespread and more extensive in coverage since the global financial crisis, which also triggered a temporary increase in the government protection of non-deposit liabilities and bank assets. In most cases, these guarantees have since been formally removed but coverage of deposit insurance remains above pre-crisis levels, raising concerns about implicit coverage and moral hazard going forward.

This paper argues that an optimal deposit insurance scheme would allow the level of insurance coverage to be determined by the market. Based on this principle, the paper proposes an insurance scheme that minimizes distortions and embodies fairness and credibility, two essential characteristics of a viable and effective deposit insurance scheme. Using a simple model for the determination of the optimal level of insurance coverage, it is shown that the optimal coverage is higher for developing compared to developed countries; a condition that is broadly satisfied by prevailing deposit insurance practices around the world.

Do deposit insurance programs contribute to financial developmen? Yes, but only if the regulatory environment is sound.
