THE EUROPEAN BANKING UNION AND CONSTITUTION In 2012, at the height of the sovereign debt crisis, European decision makers pushed for developing an ‘ever closer union’ with the formation of a European Banking Union (BU) Although it provoked widespread debate, to date there has been no coherent discussion of the political and constitutional dimensions of the European Banking Union This important new publication fills this gap Drawing on the expertise of recognised experts in the field, it explores banking union from legal, economic and political perspectives It takes a four-part approach Firstly, it sets the scene by examining the constitutional foundations of banking union Then in parts and 3, it looks at the implications of banking union for European integration and for democracy Finally it asks whether banking union might be more usefully regarded as a trade-off between integration and democracy This is an important, timely and authoritative collection ii The European Banking Union and Constitution Beacon for Advanced Integration or Death-Knell for Democracy?

potential problems of asymmetry of information between large and small Member States As already mentioned above, legal entities of banks located in the non- participating Member States would be unlikely to be significant, mostly because of asset size They could be considered significant due to the other criteria used to designate a bank as significant, namely the size of the bank relative to other banks in the Member State or the level of cross-border presence in other participating Member States For example, consider the exposure of Member States in the region to OTP Bank, a Hungarian bank present in Bulgaria, Croatia, Poland, Romania and Slovakia In this case, the Hungarian authorities could in close cooperation surrender responsibility as the home supervisor to the ECB who would be the consolidated supervisor for the group, with an impact on cooperation with authorities of other non-participating Member States, given the bank’s significant cross-border banking presence However, if OTP’s presence in those Member States was not considered material to the banking group as a whole then OTP could be supervised as a significant bank because it is one of Hungary’s three largest banks Moreover, in the case of Poland, the largest Member State in the non-participating Member State category (post Brexit31) is unlikely to experience a significant shift of banks to the SSM arrangement At most it would see its top three largest banks move, according to recent figures regarding the size of assets of Polish banks.32 The CEE Member States provide another interesting dilemma for the Banking Union While foreign banks are a crucial part of the banking system in their respective markets, they are unlikely to command the same commitment by the host authorities as would local domestic banks, since they are not the Member State’s ‘national champions’.33 The experience from the global financial crisis is one of Member States and their central banks standing behind their respective national champions, meaning that in the CEE markets such political commitments may not be forthcoming The Banking Union is not proposing to rein in integration and jeopardise the benefits of cross-border banking On the contrary, it is attempting to centralise supervision in order to better address the asymmetry of information problems of supervising and resolving cross-border banks in the different participating Member States.34 In view of this centralisation, financial support is necessary in 31 Ie after the withdrawal of the UK from the EU 32 Leading banks in Poland as of 4th

arrangements to support resolution options The move to pool resources should theoretically reduce conflicting incentives between the home and host Member States, and more specifically between large and small Member States, since the cost of resolution is likely to be different from the home and host perspective and since centralisation of supervision is not going to be enough to incentivise cooperation and coordination at the resolution level III. Wider Ramifications of Opting In or Out of the Banking Union The Member States which not participate in the Banking Union are varied and the benefits of opting in to the Banking Union need to be assessed on a caseby-case basis, since the move to close cooperation, as shown above, does not in practical terms create a level playing field between the Eurozone and those which may eventually decide to enter into close cooperation Ultimately, the linchpins are those non-participating Member States which move to adopting the euro in place of national currencies once they meet the convergence criteria It would be for the Council to decide whether those non-participating Member States have met the convergence criteria This decision would ultimately be superseded by the political will of the Member State to adopt the euro In this respect, the European Union consists of a number of subcategories of Member States, albeit there is sovereign equality in its legal foundations There are a number of considerations Member States should take into account before deciding on opting in Since the criteria are not completely transparent, albeit having sound banks and be trusted to undertake supervision is a good starting point, opting in is not a matter of right since it is the ECB that ultimately decides on this Moreover, the ability to formally showcase Member States entering into close cooperation is a signal of the ECB’s movement in a relatively short period of time towards building the reputation of being a credible supervisory authority The counterfactual is also evident, and the reluctance of Member States to enter close cooperation also signals a lack of confidence in the credibility of the ECB as a single supervisory authority, or doubts over its double role as also responsible for monetary policy for the Eurozone This results in perhaps the most important obstacle to opting in, where the governance arrangements of the ECB, notably the Governing Council, not allow for a seat for non-euro Member States This is partly addressed by enabling Member States in close cooperation to attend Governing Council meetings relating to Supervisory Board decisions when the Governing Council is of the view that the Member State in question is likely to challenge the draft supervisory decision by the Supervisory Board This is useful since it will enable the Member State to put forward its position before the Governing Council, which is generally not possible for a non-Eurozone Member 306 Dalvinder Singh State The leverage the ECB has, however, is the right to terminate the close cooperation, even if that right is shared with the opting in Member State as well But it could also signal the need for the Member State to build up the capacity and resources to demonstrate it can put a credible case forward to the ECB to enter close cooperation If one were to be elitist about the type of Member State entering close cooperation, the larger the non-participating Member State the better for the reputation of the ECB as a supervisor In view of the significant presence of EU foreign banks in the Eastern European banking market, the home and host relationship becomes very important The relatively unique position of the ECB acting as the home and the host, will be a very important factor in considering close cooperation, as it is likely to mean fewer obstacles and challenges of cooperation and coordination within the Eurozone A prospective participating Member State needs to reflect on the level of discretion it is likely to lose with the transfer of supervisory decision-making to the ECB While it is assumed that competent authorities will cooperate with one another and share information on reciprocal basis, in practice this is not always forthcoming This is a concern when it specifically relates to capital and liquidity levels It is important to consider how the underlying legal framework can propagate the home host challenges and home bias despite there being a single centralised supervisor For example, if the ECB is acting as the consolidated supervisor for a significant bank within the Eurozone, the underlying model of consolidated supervision explicitly requires that the host State supply information and data to the ECB associated with a range of Capital Requirements Regulation, Regulation No 575/2013 (CRR) matters However, the host State in this relationship is required to ‘request’ that information under the legal framework for its own purposes, ie to better supervise the subsidiary that is part of the group, especially where home State cooperation was not always forthcoming Under the Banking Union, the ECB will also act for the host so there should be improvements in term of asymmetry of information But the purpose of consolidated supervision is aimed at the interests of the group, which is likely to make the parent’s position and indeed the leverage to influence matters that much greater on the whole, side-lining the views of the Member State where a subsidiary is located but that subsidiary being immaterial to the safety and soundness of the group In the countries under consideration this is an acute problem, since the CRD IV and CRR frameworks and technical standards provide the consolidated supervisor significant discretion to act in the interests of the group rather than in a reciprocal manner Finally, a dilemma exists with the transfer of decision making to the ECB and SRB when it comes to failing institutions and planning for resolution options and assessing the best options for the local circumstances While a Single Point of Entry resolution strategy may be in place for the core part of the group, that does not negate the fact that the peripheral parts may be required to have a separate Multiple Point of Entry strategy in the form of insolvency The benefits of centralised decision making in close cooperation would be a clear awareness of these decisions ex ante and the ability to prepare for such options The decision as to whether the bank Should Member States Join the Banking Union? 307 offers critical functions regardless of whether it is significant or less significant is another challenge at the heart of how banks need to be managed when they are experiencing problems The NCA and NRA may be of the view that the bank is undertaking critical functions for the purpose of being classed an O-SII and it should equally be considered to be offering critical functions for the purposes of resolution as well However, the SRB may decide otherwise when deciding on whether a bank should be dealt with in resolution or insolvency based on recent decisions,35 see Table 12.1 However, again, the SRB would assess such options with the NRA in the resolution plans, so it is not as if the NRA would be in the dark on such matters Table 12.1 SRB Resolution Decisions Name of bank Resolution – Liquidation – ECB significant Other bank systemically

Banca SpA ✓ × × ✓ ABLV Bank Latvia (parent) ✓ ✓ × ✓ ABLV Bank Luxembourg (subsidiary) × × × ✓ The ECB relationship with a Member State in close cooperation as shown in Table 12.1 is akin to the agency relationship that the SRB exercises with Member States in the Banking Union In view of this, those Member States in close cooperation will have transferred decision making for supervision and resolution to a centralised body but the NCA and the NRA retain responsibility for executing those decisions The benefit of close cooperation, in many respects, is access to the single resolution fund and the proposed European single deposit guarantee fund (EDIS), once it is in place, as lines of defence during a crisis Those should go some way to minimise the risks of home bias especially when the level of foreign 35 See J-H Binder, M Krimminger, M Nieto and D Singh, ‘The choice between judicial and administrative sanctioned procedures to manage liquidation of banks: A transatlantic

host authority deciding ex post to ring-fence activities of the group operating in their jurisdiction to reduce local damage In view of the importance of funding during a crisis, access to the SRF and
