In two volumes, this book covers in a comprehensive, internally balanced, systematic and detailed way the field of European Union (EU) banking law and regulation. In three parts, Volume I offers a brief introduction to the role of banks in the contemporary financial system and the theory of banking regulation, a thorough analysis of international financial standards which are contained in the sources of public international banking law (and of public international financial law, in general), a detailed presentation of the gradual evolution and the sources of EU banking law, as well as a precise analysis of the law-making process and the key institutional aspects of this branch of EU economic law. The standards and rules adopted and the institutions created in the aftermath of the (2007-2009) global financial crisis and the subsequent euro area fiscal crisis, as well as during the current pandemic crisis are discussed, as appropriate. A detailed analysis of the substantive aspects ofEU banking law will follow in Volume II
