The Eurozone crisis has also had significant political implications, resulting in the fall of some national governments, and forcing EU leaders to grapple with both the euro’s future viability and the desirability of further EU integration. Some view EU efforts to address the crisis as too timid and too slow in part because of political differences among EU member states and between those in and outside of the Eurozone. Key points of tension have arisen over the proper balance between imposing austerity measures versus stimulating growth, and whether and to what extent the Eurozone countries should pursue closer fiscal integration. In January 2012, 25 of the EU’s then-27 member states agreed on a new “fiscal compact” aimed at strengthening fiscal discipline within the EU (in part by requiring national budgets to be in balance or in surplus), providing for a more automatic imposition of sanctions should a country breach EU fiscal rules, and improving the coordination of national economic policies; this pact entered into force in January 2013.
