Following 9\11 concerns were raised about the use of alternative remittance systems such as Hawala in potentially funding terrorism. This book analyses the risks such systems pose in terms of terrorist financing, offering a detailed overview of the historical origins and methods of operation of alternative remittance systems or informal value transfer systems. The book presents a detailed critique of the UK framework for the regulation of these systems in order to assess the use and effectiveness of these measures in practice. The book concludes with key recommendations to secure the regulation of these alternative remittance systems while still promoting overseas remittances.
