This book explores the potential and problems of bank safety and efficiency arising from the rapidly growing area of cross-border banking in the form of branches or subsidiaries with primarily only national prudential regulation. There are likely to be differences in the treatment of the same bank operating in different countries or of different banks from different home countries operating in the same country with respect to deposit insurance provisions, declaration of insolvency, resolution of insolvencies, and lender of last resort protection. The book identifies these protection problems and discusses possible solutions, such as greater cross-border cooperation, harmonization and organizations. The contributors to this book include experts from different countries and from a wide range of affiliations, including academia, regulators, practitioners, and international organizations.
