This book provides a commentary on the law of the EU related to the Monetary Union. It contains a comprehensive analysis of all provisions of the Statute of the European System of Central Banks (ESCB) and the European Central Bank (ECB). In addition, the book also analyses all provisions of the Treaties themselves which regulate the ESCB and the ECB. This analysis is supplemented by commentaries on other Protocols which contain relevant rules for the Monetary Union. In essence, all relevant statutory rules governing the euro and its key monetary authority, the European Central Bank, are unfolded and explained in one volume. This gives the book a unique position in the legal literature on the law of the EU. With contributions by renowned academics and practitioners, this book is an expanded and updated translation of the 2013 German commentary, EWU Kommentar zu Europaischen Wahrungsunion (Mohr Siebeck) and is an invaluable resource for practitioners and academics alike who are looking for a provision-by-provision commentary on the laws governing the European Monetary Union.
