Sovereign debt is a complex and highly topical area of law and this work represents a new main reference book on the subject bringing together contributions from world leading practitioners, scholars and regulators. Divided into five parts the book opens with a part on restructuring which analyses contractual provisions and the role of institutions such as the International Monetary Fund. The second part, on enforcement, considers the position of a sovereign as a defendant analyzing the availability of special immunities and matters of defense and arbitration pertinent to sovereign debt. Part three of the book is concerned with complicating factors such as economic, political or banking crises and how these relate and complicate the task of addressing an unsustainable sovereign debt stock. In this section the particular and topical issues concerned with restructuring in a monetary union are explained. The fourth part provides economists' explanations of why and how sovereigns borrow and the causes of a sovereign debt, which enriches understanding by providing context to the purely legal aspects of the work. The book closes with a section which covers proposed reform to sovereign debt systems. Dedicated to the leading expert Lee Buchheit, this work contains comprehensive and rigorous analysis on sovereign debt management which no specialist should be without.
