The Banking Union is the EU framework for centralised bank oversight, resting on three pillars: single supervision (the SSM), common resolution (the SRM), and a still-unbuilt European Deposit Insurance Scheme (EDIS) that would mutualise deposit guarantees across member states rather than leaving them to national funds.
How it works
Launched after the euro crisis, the Banking Union moved supervision of significant banks to the ECB (2014) and created the Single Resolution Mechanism. The third pillar, EDIS, would replace fragmented national deposit guarantee schemes with a pooled European fund, breaking the bank-sovereign "doom loop" in which weak banks and weak governments drag each other down. EDIS has been stalled since 2015 over risk-sharing versus risk-reduction disputes, chiefly German resistance to mutualising legacy risk.
Why it matters now
With 2023's regional-bank and Credit Suisse episodes fresh and fragmentation risk a live ECB concern, completing EDIS is back on the table as a test of euro-area financial integration; any 2025-2026 progress would mark a structural reduction in periphery sovereign-bank linkage.
Example
When Cyprus's banks failed in 2013, depositors above the €100,000 national guarantee faced bail-in haircuts because guarantees were nationally funded and the sovereign was itself insolvent. A functioning EDIS would have backstopped insured deposits from a euro-area-wide pool, severing the link between a member state's fiscal capacity and the credibility of its deposit guarantee.
Frequently asked
- What is the European Banking Union?
- The Banking Union is the EU framework that centralises bank supervision, resolution, and (eventually) deposit insurance for the euro area. It rests on three pillars: the Single Supervisory Mechanism (SSM, live 2014), the Single Resolution Mechanism (SRM), and the still-unbuilt European Deposit Insurance Scheme (EDIS). It was created after the 2010-2012 euro crisis to break the bank-sovereign doom loop.
- What are the three pillars of the Banking Union?
- The three pillars are single supervision, common resolution, and common deposit insurance. The Single Supervisory Mechanism (SSM) put the ECB in charge of significant banks in 2014; the Single Resolution Mechanism (SRM) handles failing-bank resolution via the Single Resolution Board; and the European Deposit Insurance Scheme (EDIS) would pool deposit guarantees. Only the first two are operational; EDIS remains stalled since 2015.
- Why has EDIS been stalled since 2015?
- EDIS has been blocked by a risk-sharing versus risk-reduction dispute, chiefly German resistance to mutualising legacy risk. Creditor states argue that pooling deposit guarantees before periphery banks clean up non-performing loans and sovereign-bond concentration would force their taxpayers to backstop others' legacy problems. The Commission's 2015 proposal has been repeatedly diluted, including a 2017 'hybrid' reinsurance compromise.
- How does EDIS differ from national deposit guarantee schemes?
- EDIS would pool deposit guarantees across the euro area, while national schemes are funded and backstopped by individual member states. Under national schemes, a guarantee is only as credible as the sovereign behind it, so depositors in a weak state face higher risk. EDIS would sever that link by drawing on a euro-area-wide fund, neutralising the bank-sovereign doom loop.
- Why does completing the Banking Union matter now?
- Completing EDIS would structurally reduce periphery sovereign-bank linkage and ECB fragmentation risk. The 2023 US regional-bank failures and Credit Suisse rescue revived urgency around deposit-run dynamics, and euro-area integration remains incomplete without the third pillar. Any 2025-2026 progress would signal genuine fiscal-financial risk-sharing rather than the reinsurance half-measures debated since 2017.
