Abstract
This chapter discusses the European Union’s (EU) response to the euro crisis that emerged in late 2009, two years after the global financial crisis struck. It identifies the challenges this crisis has posed to the existing institutional set-up of economic and monetary union (EMU) and shows that it had a lasting impact on dicussions over the EU’s future well beyond its most dramatic moments. A timeline of the euro crisis is provided and the main changes to the institutional framework of European economic governance at the time of writing are reviewed. The chapter considers whether the crisis was caused by a deficit of centralized decision-making and whether it has served, in turn, as a catalyst for deeper economic and political integration in the euro area and the Union more generally. The consequences of the crisis for the EU’s legitimacy are also explored from competing theoretical perspectives.
