Abstract. The Eurozone sustainability could become a real challenge in the current economical environment, characterized by uncertainty and lack of credibility. The issue of public debts represents a threat for the European financial system, while the coordination process of the economic policies at the Union's level is almost inexistent. The extremely high discrepancies between the budgetary balances of the member states makes the SGP or the strict fiscal rules become an utopia. The discretionary application and lack of credibility induced by SGP have worsened the perceptions on the economic system on European level, and the authorities' answer was not coherent enough, leaving room for interpretation by the Euro-skeptics.
