This book considers the growing and emerging issue of unexplained wealth and how this issue fits within the larger challenge of financial and economic crime. The collection provides a rich and robust contribution to the dearth of knowledge in this space. Contributions are drawn from legal practitioners, academics, and experts from the Global South, Global North, and the Asia- Pacific region, who share their insights into the methods and approaches that have been utilised to tackle unexplained wealth in their respective countries. Each author provides a comprehensive critique of the current regime in addressing the issue and identifies failings. The volume further considers how unexplained wealth can be recognised as an important category, similar in this respect to fraud, bribery, corruption, and tax evasion amongst others. Establishing the issue of unexplained wealth as an independent area of research, the book will be essential reading for researchers, academics, and policymakers working in the areas of financial and economic crime, banking law, and international corporate governance.
