Short of full fiscal unification – or a variant of it in the form of eurozone bonds – this increase in official resources would occur through a much-enlarged European Financial Stability Facility and a much greater commitment by the European Central Bank to long-term bond purchases and liquidity operations to support banks. Since quasi-fiscal union implies that the eurozone’s core economies could end up systematically bailing out those on the periphery, only a formal loss of fiscal sovereignty – a credible commitment by the peripheral countries to medium- and long-term fiscal discipline – could overcome the current political resistance of Germany and others.
