European Union: Minimal Conditions For The Survival Of The Euro

2016/03/20

The Eurozone crisis has shown that monetary union entails additional than just sharing monetary policies. This column, initial published on 12 February 2016, identifies four minimal conditions for solidifying the monetary union. In the case of fiscal policy, this means a decentralised solution. In the case of financial supervision and monetary policy, centralisation is unambiguously the appropriate response. In the case of a fourth condition, deficit restructuring, either approach is possible, but the authors prefer a solution that involves centrally restructuring debts while allocating costs at national level.

In this column we set out minimal conditions for the survival of the euro. Typically this issue is framed as whether European monetary integration, which reached its apogee with the euro, will presently be complemented by the political integration needed for the single currency to survive. This is how the technocrats and political intelligentsia responsible for the euro’s creation saw things; since monetary union is not possible without political union, creating the euro was a way of forcing the pace of political integration.

Limits to political integration

This is not how we see things. Over the timeframe relevant for the euro’s survival, political integration in Europe has its limits. This is what historical comparisons suggest. It took the US additional than a century inclunding the experience of a devastating civil war before it became a authentic, irrevocable political union, and Europe is only a short way down that path. The euro’s existential crisis is likely to be resolved one way or the other long before that political destination is reached.

Economic theory similarly suggests limits to European political integration. Public finance theory (e.g. Buchanan 1965) points to the existence of economies of scale in the provision of public goods (integration allows public goods like fiscal coinsurance and a well-regulated banking system to be provided additional cheaply), underscoring the advantages of political integration and centralisation. But it as well highlights the costs of centralised provision since populations are heterogeneous and preferences for public goods differ across groups and regions – costs that create understandable resistance to pooling responsibility for provision.

This tension is evident in how Europe has responded to its crisis. In some areas where evidence of increasing returns is overwhelming, Europe has moved toward centralised provision. Examples include centralised provision of backstop facilities for sovereign deficit markets (the European Central Bank’s Outright Monetary Transactions) and creation of the Single Supervisor (with responsibility for oversight of the banking system).

But in other areas the benefits of centralised provision are dominated by the costs of uniformity, creating resistance to further centralisation. This is authentic most obviously of fiscal policy where different nations have different tastes (insofar as nations as distinct from individuals have tastes) for fiscal rectitude and stabilisation, and different degrees of tolerance of deficit and deficits. This heterogeneity in turn creates a problem of trust, i.e. can those formulating and executing the common policy be trusted to do so in a manner consistent with a group’s tastes. This is analogous to the problem that results in an undersupply of public goods like policing and schools in localities where the people is heterogeneous, wherein each group is reluctant to pay additional taxes for fear that the resources so mobilised will go to pay for public goods valued by other groups but not by itself (Alesina et al. 1999).

In what follows we use these insights from theory and history to guide our discussion of minimal conditions for survival of the euro. The implication is that for the single currency to survive, Europe needs both additional political integration and less political integration. The trick is to understand at the same time as less is additional.

Initial condition

The initial of our four minimal conditions for the survival of the euro is a normal central bank able to pursue flexible inflation targeting and backstop financial markets, thereby protecting the Eurozone from potentially self-fulfilling crises. These are functions, in a monetary union that must be provided at a centralised level if they are provided at all. Given the existence of a single monetary policy, there is little scope for governments to influence domestic inflation rates. National central banks (which partner with the ECB in the European System of Central Banks) can advance credit to domestic banks requiring liquidity only against eligible collateral and with the approval of the ECB to provide emergency liquidity assistance (ELA). Sovereigns, not having recourse to a national central bank, have limited ability to backstop their financial markets unilaterally.

As conceived initially, the ECB did not provide these functions. The bank’s two-pillar strategy focused not just on inflation but as well on increase of a talismanic monetary accumulation that bore no stable relationship to inflationary outcomes. Rather than adopting a symmetric inflation target, it pursued a target of less than but close to 2%, dangerously skirting deflationary territory. Under the presidency of Jean-Claude Trichet, it concentrated on headline rather than core inflation, leading it to raise interest rates in 2008 and 2011 at the same time as deflation was the fundamental underlying danger. It threatened to terminate the emergency liquidity assistance for Ireland in 2010 unless its government applied for a bailout and agreed to a programme of austerity and bank recapitalisation (ECB 2014). It stopped liquidity assistance for Greece in 2015 until the government agreed to a programme rejected by voters in a referendum. It hesitated to adopt unconventional monetary policies at the same time as interest rates fell to the zero lower bound. It was reluctant to intervene with purchases of government bonds at the same time as investors doubted the ‘essential cohesion’ (Draghi 2014) of the Eurozone, fearing that the German Constitutional Court would policy such action incompatible with that country’s Basic Law.

Hearteningly, the ECB has presently moved some distance in the direction of becoming a normal central bank. Quantitative easing in March 2015 demonstrated that the members of its Governing Council understood the appropriate and particularly dangerous nature of deflation. In its day-to-day operations, the ECB entirely shelved the monetary pillar and presently additional carefully and systematically distinguishes core from headline inflation. While a symmetric inflation target and a smaller, nimbler monetary policy committee are still required, these are steps in the requisite direction.

What is presently required to cement this evolution?

  • Initial, the ECB needs to heighten its transparency to correspond with its better discretion and the breadth of powers invested in a normal central bank.

Transparency is a mechanism for holding an independent central bank accountable in the court of public opinion. It is a way of communicating to constituents that policies are being implemented with the common good and not particular national interests in mind. If the presence of national representatives on the Governing Council is an obstacle to taking and publishing formal votes, again this is an argument for reorganising the Council to reduce and eliminate the presence of those national representatives. Doing so would be a very limited step in the direction of better political integration but a necessary one for survival of the euro.

  • Second, the ECB, at the same time as undertaking purchases of government bonds in the context of quantitative easing or conventional open market operations, needs assurance that its decisions will not be disallowed by the German Constitutional Court.

This may require a change in Germany’s basic law or an unambiguous statement by its Constitutional Court that it will accept the judgment of the European Court of Justice on ECB-related matters. Changing this aspect of the basic law to conform to EU jurisprudence would be a limited step in the direction of political integration.

Second condition

A second minimal condition for the survival of the euro is completing Europe’s banking union. The crisis has underscored how banking-system stability is a Eurozone-wide public good subject to strongly increasing returns. One need only recall how lax regulation of French and German banks allowing these institutions to lend hand over fist to southern European nations helped to set the stage for the crisis, or how the subsequent problems of some banks again threatened to destabilise others via the interbank market and related mechanisms. For good and bad reasons, member states harbour somewhat different tastes about precisely how they prefer to supervise and resolve their banks. But experience has shown that this is an area where strongly increasing returns from centralised provision dominate costs of uniformity. As the point is sometimes put, monetary union without banking union will not work.

To this end, Eurozone member states (and other EU member states that choose to opt in) have created a Single Supervisor of financial institutions, locating the Supervisory Board in the ECB. The Single Supervisory Mechanism oversees large financial institutions and works closely with national supervisors overseeing other intermediaries. The Single Supervisor has by presently intervened to enhance the public good of financial stability, for example, by limiting the exposure of Greek banks to the Greek government and additional generally by pressing the banks it supervises to reduce home bias in their sovereign bond portfolios (Veron 2015).

In addition, the European Parliament and Council have adopted a common mechanism for resolving failed financial institutions, the Bank Recovery and Resolution Directive. This obliges all EU governments to bail in unsecured creditors before tapping taxpayer funds, requiring members to implement these rules through national legislation. Again, these are limited but necessary steps in the direction of financial and political centralisation.

The ‘political bridge too far’ has been the creation of a common bank deposit guarantee fund in which money from all Eurozone members will be pooled to guarantee that bank accounts up to €100,000 are fully insured. Under the terms of the banking union, member states are presently required to establish conforming insurance schemes for accounts up to this ceiling, the crisis having shown that non-uniformity and, in some cases, the absence of deposit insurance can threaten confidence and financial stability monetary-union wide. But deposit insurance is only confidence inspiring if the funds standing behind it are adequate to meet potential claims, and the members of a monetary union, not being able to resort to central-bank finance, may find it difficult approaching up with the necessary funds in extremis. This is why deposits in the US, following experience with national bank holidays in the 1930s, are federally rather than national insured.

Some nations, notably Germany, worry that other members will be additional prone to draw on the fund (German commentators regularly cite Greece as a case in point). They reject mutualisation of deposit insurance as a de facto fiscal transfer. The response comes in three parts. Initial, banking stability is a precious public good subject to sufficiently increasing returns that centralisation of the deposit-insurance function is warranted. Second, all member states, not least Greece, are required to implement the banking union’s new resolution rules to limit taxpayer liability. Third, this is a limited and specific mutualisation of fiscal powers targeted at a specific financial problem intimately associated with monetary union, not the wholesale centralisation of fiscal control at the level of the EU or the Eurozone.

Third condition

This of course begs the question of whether the wholesale centralisation of fiscal functions is desirable – whether, as the point is sometimes put, monetary union without fiscal union will not work. Since the Maastricht Treaty and the Stability and Increase Pact, there have been repeated efforts to centralise EU fiscal policies. These early attempts have presently been supplemented by further initiatives by the European Commission, inclunding the Six Pack, the Two Pack, the European Semester, and a new treaty (the Treaty on Stability, Coordination and Governance in Europe).

The one thing these measures have in common is that they do not work. EU member states have profoundly different preferences with regard to fiscal policy. They are reluctant to mutualise fiscal resources or delegate decisions over national fiscal policies to the Commission and the European Parliament, since the consequent decisions would differ markedly from the preferences of some members. How taxes are raised and public spending is structured are intimately bound up with the details of country’s culture and history. Fiscal policy is fundamentally political and distributive, limiting delegation even at the national level. From the start, it was evident that EU members were reluctant to interfere in such matters (Eichengreen and Wyplosz 1998). It is unclear why the next should be different from the completed.

To be sure, fiscal policy has some of the characteristics of a public good. Its macroeconomic effects spill across borders, and fiscal instability in one country can create instability in other nations insofar as one country’s banks invest heavily in other nations’ bonds and fiscal crises are met with multilateral bailouts. But the notion that there are strongly increasing returns from centralisation can be questioned. The magnitude of direct cross-border spillovers is limited; additional deficit spending by Germany raises the request for Italian exports but as well drives up interest rates in Italy, partially offsetting the initial result. If cross-border spillovers result from the bank-sovereign doom loop, again the solution is to prevent banks from holding concentrated positions in sovereign bonds as the Single Supervisor is seeking to do. If the source is pressure for multilateral bailouts, again the solution is a no-bailout policy.

Is there an alternative to this doomed effort to centralise fiscal policy at the level of the Union? We would answer yes: it is to renationalise fiscal policy. This is our third minimal condition for the survival of the euro. The fiction that fiscal policy can be centralised should be abandoned, and the Eurozone should acknowledge that, having forsaken national monetary policies, national control of fiscal policy is all the additional significant for stabilisation. If reckless national fiscal policies endanger the banks, again the banks should be prohibited from holding sovereign bonds. There is no reason why a no-bailout policy of the sort enforced for US national governments since the mid-19th century would not again be credible. Absent expectations of a bailout, investors will pay better attention, and market discipline will be additional intense. Governments in turn will have additional incentive to strengthen their fiscal institutions and procedures so as to deliver better outcomes.

Fourth condition

Making effective use of fiscal policy for stabilisation presupposes removing inherited deficit overhangs in whose presence fiscal policy is unavailable. Removing those overhangs is thus our fourth precondition for survival of the euro.

The question is whether this process is best organised at the national or EU level. Arguments can be made for both approaches. On the one hand, fiscal positions and thus preferences over restructuring differ across member states. Nations with unsustainable debts will prefer to see them restructured, whereas additional lightly-indebted nations will fear losses and reputational consequences. Public choice theory points to the existence of costs of uniformity and centralisation in the presence of such heterogeneity.

On the other hand, the benefits of a centrally coordinated, encompassing approach are compelling at the same time as the survival of a public good, the euro itself, hinges on the outcome. A piecemeal approach in which a few nations regain fiscal flexibility but others do not is unlikely to permit to the repatriation of fiscal policy to the national level, violating an extra of our key conditions for the survival of the euro. Individual nations may be discouraged by the stigma attached to restructuring and by the associated poor credit ratings and risk premia, with the predictable result that no country will want to go it alone, or even to go initial. An encompassing approach where deficit overhangs are reduced across the Eurozone, allowing fiscal control to be delegated to the governments of all participating member states, will help to replace the macroeconomic and financial stability on which the euro’s survival depends.

A centrally coordinated approach can as well help to surmount two further obstacles to restructuring. Initial, it may be better able to overcome resistance from debtors. Banks in one Eurozone country will typically hold bonds issued by the government of an extra, and European institutions like the ECB hold national debts. If one country restructures its debts, it will impair the balance sheets of its own banks but as well of banks in other nations. Isolated deficit restructurings do not take this externality into account, whereas a collective approach can do so. It can distribute losses due to these externalities in a lot of ways, inclunding assigning them entirely to the country doing the restructuring. Whatever the solution chosen, the point is that under the collective approach there will be an agreement on burden sharing. If the agreed solution involves transfers – which is not necessarily the case, as shown below – again it will have to be agreed by officials of each country on behalf of its taxpayers rather than being imposed by a foreign authority.

The second obstacle is that deficit restructuring may be seen as an encouragement to accumulate large debts someday in the expectation that they will be restructured again. Weakening the bonding role of deficit is therefore a source of moral hazard. Collective action may help to remove these objections. Member states will be aware of the risk and will request incentives to require guarantees that nations will not act unilaterally and opportunistically someday. The guarantees, which may take various forms (an example is provided below) may not be iron-clad, but they should be compared to how the issue is dealt with under the unilateral approach.

Several proposals have been advanced along these lines (see inter alia Buchheit et al. 2013, Corsetti et al. 2015 and Pâris and Wyplosz 2014). Pâris and Wyplosz (2014) for example propose replacing a significant part of all outstanding public debts with zero-coupon perpetuities. Under their proposition, the cost of the restructuring to European institutions like the ECB can be fully financed by seigniorage gain. If debts are retired in proportion to shares of national governments in the capital of the ECB, again the benefit (deficit write-down) for each country is exactly matched by the cost it incurs (the seignorage gain it relinquishes). In this case there is no loss to debtholders and no transfer across nations. Enforcement is guaranteed by a commitment to convert the perpetuities back into debts in the event of non-compliance with the agreement. Since all nations participate, there is no stigma.

One can imagine other schemes for collectively restructuring the deficit overhang of Eurozone members. But irrespective of the details, some scheme must be adopted to restructure public debts comprehensively enough for Eurozone member nations to recover the use of their national fiscal policies. The general point is that this kind of comprehensive restructuring is easier and less costly at the same time as carried out collectively. Once fiscal discipline and low national public deficit are completed, the no-bailout clause will have to be completed by a prohibition on ECB dealings in an individual country’s deficit instruments. If the ECB is able, even in theory, to purchase the debts of a government that gets into fiscal trouble, fiscal discipline enforced by the no-bailout policy will be incomplete. There is no need for such a prohibition in the US, since the Federal Reserve deals in federal government bonds, not the bonds of particular states. Creating the equivalent regime in the Eurozone would require limiting ECB bond-market transactions to the institution’s own deficit instruments, Eurobonds, and bonds purchased in proportion to the central bank’s capital key. Thus, the new regime would permit quantitative easing (under which bonds are purchased according to the capital key) and open market operations structured analogously, but not Outright Monetary Transactions, under which the ECB purchases the bonds of an individual troubled economy, on that country’s request.

Concluding remarks

The Eurozone crisis has shown that monetary union entails additional than just sharing monetary policies, and that the common central bank must aim at additional than just price stability. While completing the architecture is challenging, doing so does not require a forced march to political union. Club theory suggests that a political union is not justified at this stage.

That theory as well sheds light on desirable ways of addressing the problems exposed by the crisis. We have identified four minimal conditions for solidifying the monetary union. In one case, fiscal policy, this means a decentralised solution. In the case of two other conditions, financial supervision and monetary policy, centralisation is unambiguously the appropriate response. In the case of a fourth condition, deficit restructuring, either approach is possible, but we prefer a solution that involves centrally restructuring debts while allocating costs at national level.

These conditions, while necessary, are sufficient as well, or at least we hope. They should be enacted as quickly as possible.
