This book addresses 3 questions: is money a way to create a European Union identity? If so, which type of identity is this? And in what ways is the EU identity changing? The book brings together experts from a variety of backgrounds and academic approaches to analyse the law of money and payments on the one side, and the law of capital and investments on the other.The book is divided into 2 parts. Part I covers scriptural, electronic, and digital money. It analyses the European framework for payment services users, explores limits and challenges of the Banking Union, and looks at the project for a digital euro. Part II investigates the policy and regulatory drivers of the EU's changing identity, from the early modern roots of the European law of money and capital to the regulatory strategy set in the Capital Markets Union and the role conferred on venture capital; from the fintech-based developments of payment systems to the newly-established fiscal and monetary policies in the post-COVID phase. The book will be of interest to researchers, academics and policy makers in the fields of law and regulation, as well as political economy and political sciences.
