Exit strategies, capital flight and speculative attacks: Europe's version of the trilemma

Abstract

In the winter 2011/12, a wave of internal capital flight prompted the ECB to abandon its exit strategy and announce an unprecedented monetary expansion. We analyze this episode in several dimensions: (i) we provide an event-study analysis, covering key variables from national central banks' balance sheets, (ii) we rationalize the empirical patterns in a formal discussion of the constraints in a monetary union and (iii) we analyze different indicators of redenomination risk in the euro area. Finally, we argue that the euro area entails an inherent policy trilemma that makes it prone to speculative attacks.
