Conventional wisdom has it that the eurozone cannot have a monetary union without also having a fiscal union. Euro-enthusiasts see the single currency as the first steppingstone toward a broader economic union, which is their dream. Euroskeptics do, too, but they see that endgame as hell -- and would prefer the single currency to be dismantled. The euro crisis has, for many observers, validated these notions. Both camps argue that the eurozone countries’ lopsided efforts to construct a monetary union without a fiscal counterpart explain why the union has become such a mess. Many of the enthusiasts say that the way forward is for the 17 eurozone countries to issue euro bonds, which they would all guarantee (one of several variations on the fiscal-union theme). Even the German government, which is reluctant to bail out economies weaker than its own, thinks that some sort of pooling of budgets may be needed once the current debt problems have been solved.
A fiscal union would not come anytime soon, and certainly not soon enough to solve the current crisis. It would require a new treaty, and that would require unanimous approval. It is difficult to imagine how such an agreement could be reached quickly given the fierce opposition from politicians and the public in the eurozone’s relatively healthy economies (led by Finland, Germany, and the Netherlands) to repeated bailouts of their weaker brethren (Greece, Ireland, Italy, Portugal, and Spain). Moreover, once the crisis is solved, the enthusiasm for a fiscal union may wane. Even if Germany is still prepared to pool some budgetary functions, it will insist on imposing strict discipline on what other countries can spend and borrow. The weaker countries, meanwhile, may not wish to submit to a Teutonic straitjacket once the immediate fear of going bust has passed.
But there are more than just two ways forward: fiscal union or a breakup of the euro. There is a third and preferable option: a kind of market discipline combined with tough
