In Defense of European Deposit Insurance



Last November, the European Commission published a proposal for a European Deposit Insurance Scheme (EDIS), which is currently being negotiated among EU member states. Yesterday, this elicited a critique from Ludger Schuknecht, the German Federal Finance Ministry's respected chief economist. While his objections to EDIS are not new, they have rarely been articulated with such clarity, at least in the English-speaking debate, and deserve careful consideration.

As it happens, none of his arguments of policy substance is compelling. By contrast, the obstacles he highlights in terms of Germany's politics and political economy are real enough and will ultimately play a big part in determining the EDIS negotiation's outcome. (Disclaimer: As always at Bruegel, this blog post expresses a personal opinion of the writer and can in no way be described as an institutional position of Bruegel. The German Finance Ministry has generously and continuously contributed to Bruegel's funding and governance since its creation in 2004.)

There are two major oversights in Schuknecht's anti-EDIS diatribe, respectively about deposit insurance and about banking union. Correcting these would radically shift the balance of his arguments, and reverse his conclusions.

First, deposit insurance. While it carries the same name, this policy does not raise the same moral hazard issues as, say, fire insurance or theft insurance. Trust in deposits is a fundamental layer of confidence that underpins economic activities in developed countries. When it is compromised, so is social cohesion more broadly. The EDIS would only guarantee deposits up to the European limit of EUR 100,000. No government would want to voluntarily trigger bank failures, including losses on uninsured deposits, and thus precipitate its own demise. Indeed, an EDIS would better align governments' incentives with the financial stability objective than the current framework does. As Schuknecht himself concedes, EDIS would mean "central banks would not have to jump in with emergency liquidity assistance quite as quickly" as in the recent past, thus imposing more discipline on bank creditors and policymakers. Neither Greek prime minister Alexis Tsipras nor ex-finance minister Yanis Varoufakis advocated haircuts on uninsured Greek deposits last year. The idea that rogue politicians would annihilate financial activity in their jurisdiction for the sake of making the Germans pay is a case of worrying more about imaginary than real risk scenarios.

Indeed, Germans should be more sensitive than most to the counterarguments. The last bank run in Germany was in 1931, triggered by the collapse of Creditanstalt in nearby Austria, and played a role in the tragic developments of the following years. Postwar Germany has built an elaborate system of private and public institutional protections to ensure this doesn't happen again, at the risk of creating a lot of moral hazard among the banks' creditors. Since the onset of financial crisis in 2007, numerous banks have failed in Germany, but not a single bank creditor, no matter how junior, has lost money on their claims—in contrast to most other euro area countries such as Austria, Cyprus, Greece, Ireland, Italy, the Netherlands, Portugal, Slovenia, and Spain. Savings banks protect each other, as do cooperative banks, and savings banks are often additionally cushioned by their public-sector stakeholders. Even private institutions benefit from mutual protection: A year ago, tiny Düsseldorfer Hypothekenbank was expensively bailed out by a national guarantee fund of the commercial banks, "in order not to damage the reputation of Germany as a place to do banking business." Few countries are as committed as Germany to prioritizing financial-sector safety nets over theoretical moral hazard arguments.

Second, banking union. Schuknecht's article curiously ignores both the rationale for it and the new realities on the ground, as if to hark back to a pre-2014 era when banking systems were essentially national. The motivation for banking union, including the creation of the Single Supervisory Mechanism (SSM), was the objective of breaking the vicious circle between banks and sovereign states, which left the euro area at serious risk of break-up in mid-2012. The SSM was reportedly first proposed by none other than German finance minister Wolfgang Schäuble. When Schuknecht implies the SSM will be unable to enforce sound capital discipline because "national supervisors will always remain important," he underplays his minister's achievement in fostering a broadly robust and credible SSM that is now the licensing authority for all banks in the euro area, not only the larger ones. The German government also endorsed the Single Resolution Mechanism (SRM), a construct that is arguably less robust than the SSM but entails a significant degree of risk-sharing, including a late-2013 common "Statement of Eurogroup and ECOFIN Ministers on the SRM Backstop" (available here). A resilient banking union needs an EDIS, as countless economists but also the International Monetary Fund and European Central Bank have insisted together with the European Commission. Without an EDIS, national budgets remain the backstop for national deposit insurance schemes that rely principally on the quality of European-level supervision—a potentially more damaging misalignment of incentives than the ones Schuknecht denounces. More fundamentally, the continuation of national deposit insurance perpetuates the highly destabilizing vicious circle between national banks and their home states in the euro area, as last year's developments in Greece illustrated once again.

When Schuknecht affirms that "the risk of bank runs is today far lower than it was before the crisis," he strangely ignores this stark reality. Last September, a controversial non-paper from the German government started with the reaffirmation of the "key objective (…) to decouple banking sector risks from public sector risks and thereby breaking the vicious link between sovereign risks and bank risks." By failing to even mention the existence of the bank-sovereign vicious circle, Schuknecht lags well behind his employer, let alone the broader European policymaking community.

In sum, Schuknecht's points of policy substance are less than compelling, and he himself sounds strangely unconvinced by them: His article starts with a reminder of many of the advantages of the EDIS proposal, which he portrays as "in themselves strong arguments." The nub of the matter lays elsewhere—in current German domestic politics and political economy. The EDIS proposal would create challenges for Germany's idiosyncratic pillar-based systems of deposit insurance, namely those for politically influential savings banks and cooperative banks that Schuknecht refers to obliquely as "the existing guarantee systems in certain countries"—actually such autonomous subnational systems are now a unique German feature. The broader political challenge is the willingness of the German public to accept further risk-sharing with euro-area neighbors. It is not a legal issue.

Schuknecht's insistence that the EDIS proposal is legally unsound or would require "the approval of all countries [instead of qualified majority] and changes to the European treaties" contradicts Germany's past approval of the SRM Regulation of 2014, which is based on the same legal framework of the Internal Market as the EDIS would be. Rather, the problem is, as Schuknecht writes, "the political risks arising from the mutualization of liability." But in truth, this mutualization is inherent in the German Chancellor's oft-repeated insistence that the integrity of the euro area must absolutely be defended. The real debate is not abstract, about mutualization or no mutualization in a single currency area, but practical, about how to minimize perverse incentives, moral hazard, and risks to financial stability. From that perspective, and even with awareness of the undeniable reticence of German local banks and of significant parts of the German public, the adoption of EDIS would be an important step forward.
