Presentation of a talk given at University of Luxembourg. The Cyprus crisis is one of the most complex in the Eurozone, although in absolute terms the problem is insignificant. Inflows of foreign deposits in excess of 700% the island’s GDP allowed a «perfect crisis» to form and contagion from Greece destroyed overnight 23.6% of the GDP. Rescue efforts were (mis)guided by a confluence of European and local politics, conflicting analyses of the problems, and forbearance from the supervisors. Bank depositors were bailed-in, making international headlines. We will argue that the bail-in is a viable solution to banking crises but with potential significant adverse effects. http://wwwen.uni.lu/universite/actualites/evenements/grande_conference_how_to_sink_an_island_mixing_politics_and_economics_in_the_cyprus_crisis
