In light of the handover from the European Central Bank President Mario Draghi to Christine Lagarde in November 2019, this book provides an in-depth analysis of the events which unfolded since the euro area sovereign debt crisis in 2010 up until today. The book focuses on the far-reaching implications of the last decade, shedding light on a wide spectrum of political, economic and financial aspects of the European poly-crises and how monetary policy reacted to these challenges. The book places particular emphasis on the tensions that the supranational central bank was subject to during this period, and on their outcomes in terms of the policies, their legitimacy, and their public reception. As such, this book will be relevant not only to understand the political implications of the past crisis but also, and foremost, in understanding what is next .
