This comprehensive and essential Commentary examines both the origins and effect of the EU’s 2015 Payment Services Directive (PSD2). Addressing a significant gap in the available literature, the book is divided into two parts: Part I analyses the legislative provisions of the Directive, while Part II explores the PSD2 implementation experience in selected EU Member States as well as in the United Kingdom. Key features include: • An innovative, systematic analysis of the Directive by leading scholars and practitioners • An in-depth legal and economic examination of the Directive’s provisions and how they relate to other relevant EU legislation • A comprehensive guide to the Directive’s implementation in a number of EU member states with reference to national legislation and jurisprudence The original analytical approach will ensure that this Commentary proves to be crucial reading for scholars of EU financial, banking and consumer protection law. It will also be a critical resource for practitioners, compliance and authority officers, and other professionals working in this field.
