EU's Biggest Economies Push to Finally Complete the Banking Union

The governors were careful to frame their request as simplification, not deregulation. The letter explicitly stated the review should ensure a “level playing field with other major jurisdictions” while maintaining the resilience of the banking sector . This distinction was critical: the governors wanted fewer obstacles to cross-border activity, not a relaxation of safety standards.

The letter triggered two immediate institutional responses. First, the European Commission announced it would conduct a wider review of EU banking rules, with reporting expected in 2026 . Second, the ECB Governing Council created a High-Level Task Force on Simplification (HLTF), chaired by Vice President Luis de Guindos and including the governors of France, Germany, Italy, Estonia, and Finland .

The Competitiveness Problem: Trapped Capital and Fragmented Markets

The governors’ frustration was rooted in measurable dysfunction. According to industry analysis cited in the Banking Union reform debate, over €225 billion in capital and €250 billion in liquidity remain trapped in subsidiaries of EU banking groups due to the absence of cross-border waivers . A territorial regulatory approach means capital and liquidity cannot flow freely within a single banking group operating across multiple member states .

The European Commission’s targeted consultation on banking-sector competitiveness, launched in response to the governors’ pressure, identified three categories of obstacles :

1. Incomplete Banking Union. The absence of a European Deposit Insurance Scheme and liquidity-in-resolution arrangements means the Banking Union remains structurally unfinished .
2. Non-prudential barriers. Divergent insolvency law, company law, investor protection rules, labour law, consumer law, and taxation create a patchwork that makes cross-border operations costly and complex .
3. Regulatory ring-fencing. National discretions, territorial macroprudential tools, and inefficient intra-group financial support arrangements prevent banks from operating as unified entities .

The consultation concluded that EU banks face obstacles to leveraging the benefits of a single market that are “not directly related to the prudential requirements,” including traditional factors such as language, culture, and domestic preferences . The overarching goal, endorsed by the European Parliament, is to create a single jurisdiction for cross-border banks that is “country blind” from regulatory, supervisory, and crisis management viewpoints .

Specific Reforms on the Table

Multiple EU bodies have now published concrete reform proposals. The following are the most significant.

Simplified Prudential Framework

In December 2025, the ECB Governing Council endorsed recommendations from the High-Level Task Force on Simplification. The reforms aim to reduce the number of elements in the risk-weighted and leverage ratio framework, introduce a materially simpler prudential regime for smaller banks, and establish a European governance mechanism that takes a holistic view of overall capital levels .

Specific recommendations include :

• Expanding proportionality under the existing Small and Non-Complex Institution (SNCI) regime.
• Reciprocating macroprudential measures automatically up to a defined threshold, paired with more standardised application.
• Refocusing EU prudential rules to prioritise clarity and consistency.

Removal of Barriers to Cross-Border M&A

The Single Resolution Board (SRB) has proposed targeted amendments to microprudential intervention and crisis management rules with the explicit purpose of boosting cross-border mergers and acquisitions . The SRB’s framework is governed by three principles :

• A default approach for reduced prudential requirements applied to subsidiaries, combined with the lifting of restrictions on intragroup exposures.
• Particular treatment for cross-border groups that meet structural and prudential criteria.
• A regulatory architecture that strengthens banks’ capital and funding capacity while enhancing financial integration.

The European Parliament has reinforced this direction, calling for legislation that treats cross-border banking within the Banking Union “on the same level as national banking” and supports the internal cohesion of large banking groups .

Single Jurisdiction Treatment

The ECB Governing Council, in its April 2026 response to the Commission’s consultation, called for the euro area to function “more as a single jurisdiction in terms of financial regulation” . This proposal, endorsed by all euro area central banks, would mean capital and liquidity can flow freely within a cross-border banking group .

The Governing Council explicitly urged synchronised progress on all Banking Union components, including concrete steps toward EDIS “with a clear timetable for implementation,” alongside deeper capital markets through the Savings and Investment Union .

Financial Infrastructure and Payments

The ECB’s simplification agenda extends beyond prudential rules to the financial infrastructure in which banks operate, including cross-border payment systems . Separately, the European Banking Authority (EBA) has identified impediments to the cross-border provision of banking and payment services, calling for an update to the Commission’s 1997 Communication on the freedom to provide services to account for technological developments .

EDIS: The Third Pillar Returns to the Agenda

The European Deposit Insurance Scheme (EDIS) was first proposed by the Commission in November 2015 as the third pillar of the Banking Union, alongside the Single Supervisory Mechanism and the Single Resolution Mechanism . The original proposal envisioned a three-stage build-up over eight years :

1. Re-insurance (to 2020). EDIS would provide liquidity assistance and absorb a portion of losses for national deposit guarantee schemes.
2. Co-insurance (to 2024). EDIS would share losses with national schemes, with the European share gradually increasing.
3. Full insurance. The European Deposit Insurance Fund would fully cover payouts.

EDIS stalled politically for years. The February 2025 governors’ letter and the subsequent ECB task force revived it as a central demand. The Eurosystem’s response to the Commission consultation in April 2026 called for “concrete steps towards the finalisation of a European Deposit Insurance Scheme (EDIS), with a clear timetable for implementation” . The Council of the EU’s working party continues to review the proposal .

The revival of EDIS is not merely institutional tidying. Proponents argue it would break the "doom loop" between sovereigns and banks by weakening the link between national fiscal health and deposit protection, delivering a genuinely integrated banking market .

The Broader Coalition: From Four to Six

While the initial simplification push came from the central bank governors of Germany, France, Italy, and Spain, the political coalition has since expanded. The finance ministers of these four countries, joined by the Netherlands and Poland—informally known as the “E6”—have issued multiple joint letters pushing for faster financial integration .

In March 2026, the E6 urged the EU to agree by summer on proposals to strengthen oversight of financial market infrastructures and improve cross-border operations . By May 2026, they detailed six priority areas for the Markets in Financial Instruments Regulation (MiFIR) and Markets in Financial Instruments Directive (MiFID) package, including cross-border fund distribution, consolidated tape, and centralised supervision of systemic market infrastructures under ESMA .

The expansion from a central bank governors’ initiative to a finance ministers’ coalition signals that the debate has moved from technical regulation to political priority. The joint position paper signed by France, Germany, Italy, Latvia, the Netherlands, and Spain in late 2025 further embedded the simplification agenda within the broader Savings and Investment Union .

What the Sources Don’t Yet Show

The available documents do not provide specific fiscal or inflation data for France, Italy, and Spain that directly link their domestic economic pressures to the cross-border banking push . However, the framing of the reforms—competitiveness, capital and funding capacity, and the ability of banks to support the real economy—suggests the underlying motivation is economic growth rather than immediate fiscal necessity .

The governors’ letter focused on competitiveness with global players, not domestic budget pressures, and the EU-level responses have emphasised market integration and simplification, not loose credit conditions. The available evidence does not support drawing a direct causal line from national inflation or debt levels to the specific regulatory proposals, and such a claim would overstate what the sources establish.

The Path Forward

The coalition’s agenda is moving on multiple tracks simultaneously: the ECB task force recommendations are being implemented, the Commission’s competitiveness review is underway, and EDIS is back in Council working-party discussions for the first time in years . The E6’s parallel push on capital markets integration and centralised supervision under ESMA suggests the ambition extends beyond banking into the architecture of European finance itself .

What remains unresolved is whether the political consensus holds when concrete EDIS timelines and cross-border loss-sharing mechanisms are negotiated. The governors’ insistence that simplification must not mean deregulation has so far kept the coalition intact, but the hardest phase—turning principles into binding rules—is only beginning.

For now, the direction is clear: Europe’s largest economies have concluded that a fragmented banking market is a structural weakness, and they are deploying the full institutional toolkit to fix it.
