Abstract: | When entering a monetary union, member countries change the nature of their sovereign debt in a fundamental way; that is, they cease to have control over the currency in which their debt is issued. As a result, financial markets can force these countries’ sovereigns into defaulting. This makes the monetary union fragile and vulnerable to changing market sentiments. It also makes it possible that self‐fulfilling multiple equilibria arise. I analyse the implications of this fragility for the governance of the Eurozone. I argue that the role of the European Central Bank as a lender of last resort is crucial in reducing the fragility of the Eurozone. In addition, steps towards a budgetary union are key in structurally strengthening the union. |
