The fiscal implications of a banking union. Bruegel Policy Brief 2012/02 [3?], September 2012

Systemic banking crises are a threat to all countries whatever their development level. They can entail major fiscal costs that can undermine the sustainability of public finances. More than anywhere else, however, a number of euro-area countries have been affected by a lethal negative feedback loop between banking and sovereign risk, followed by disintegration of the financial system, real economic fragmentation and the exposure of the European Central Bank. Recognising the systemic dimension of the problem, the Euro-Area Summit of June 2012 called for the creation of a banking union with common supervision and the possibility for the European Stability Mechanism to recapitalise banks directly.

Europe's single supervisory mechanism and the long journey towards banking union. Bruegel Policy Contribution 2012/16, 4 October 2012

Problems in the banking system are at the core of the current crisis. The establishment of a banking union is a necessary (though not sufficient) condition for eventual crisis resolution that respects the integrity of the euro. The European Commission’s proposal for the establishment of a Single Supervisory Mechanism and related reform of the European Banking Authority (EBA) do not and cannot create a fully-fledged banking union, but represent a broadly adequate step on the basis of the leaders’ declaration of 29 June 2012 and of the decision to use Article 127(6) of the treaty as legal basis. The proposal rightly endows the European Central Bank (ECB) with broad authority over banks within the supervisory mechanism’s geographical perimeter; however, the status of non-euro area member states willing to participate in this mechanism, and the governance and decision-making processes of the ECB in this respect, call for further elaboration. Further adjustments are also desirable in the proposed reform of the EBA, even though they must probably retain a stopgap character pending the more substantial review planned in 2014.

Banking Union: Ireland vs. Nevada, an illustration of the importance of an integrated banking system. CEPS Commentary, 18 October 2012

Despite their surprising similarities – in size and their housing booms – Ireland and the American state of Nevada sharply parted company when it came to who bore responsibility for bailing out their failed banks when the booms turned to bust. This latest Commentary by Daniel Gros vividly illustrates the importance of that difference and thus the shock-absorbing capacity of an integrated banking system and a banking union.
