For months, Germany’s government treated UniCredit’s advance on Commerzbank as an unwelcome intrusion. Now it is ready to talk, albeit only on its own terms.
Senior German government officials have signalled they are willing to discuss selling Berlin’s remaining 12.7 per cent stake in Commerzbank to UniCredit SpA. The condition: the Italian bank must first agree on a joint strategic plan for the combined entity.
It marks a dramatic reversal from June, when Germany’s finance agency formally rejected UniCredit’s offer. Back then, officials cited concerns about the premium and the broader approach.
The road to 47.6 per cent
The shift follows a public statement by Chancellor Friedrich Merz on 15 July, when he declared that the government was not blocking the deal. Weeks later, officials have moved further still — from resistance to conditional engagement.
UniCredit launched its voluntary exchange offer for Commerzbank in March 2026, valuing the German lender at €35bn. By 3 July, after an additional acceptance period, the Italian bank had secured roughly 47.6 per cent of shares, representing 49.7 per cent of voting rights — all pending regulatory approvals. On 17 August, UniCredit published a notice confirming that one offer condition, regulatory clearance, had been fulfilled.

Germany’s stake in Commerzbank dates to the 2008 financial crisis, when the government injected billions of euros to keep the lender afloat. Commerzbank currently holds about 12 per cent of its own shares through buybacks, making it the second-largest shareholder after UniCredit.
The European Central Bank (ECB) — the eurozone’s banking supervisor under the Single Supervisory Mechanism (SSM), established by Regulation 1024/2013 — has been moving in UniCredit’s favour. An internal ECB document from 12 August indicated that its Supervisory Board leans toward approving the acquisition. A final decision is likely in the fourth quarter of 2026.
A test for the Banking Union
The timing creates pressure on Berlin. If the ECB grants approval before Germany and UniCredit agree on a strategic plan, the government’s negotiating leverage shrinks considerably. The fourth quarter of 2026 is shaping up to be decisive: if UniCredit secures ECB approval and reaches a strategic agreement with Berlin, the deal could close before year-end. If talks stall, UniCredit may find itself holding 47.6 per cent of Commerzbank — just below the majority threshold, with no clear path to full control.
The deal is more than a corporate transaction. It is the largest cross-border EU banking merger since the global financial crisis, and it is unfolding at a pivotal moment for Europe’s Banking Union. That union rests on two completed pillars — the SSM and the Single Resolution Mechanism (SRM), created by Regulation 806/2014 — and one that remains unfinished: the European Deposit Insurance Scheme (EDIS).
Germany’s long-standing resistance to EDIS has centred on a fear that its domestic deposit-guarantee funds would end up backstopping foreign-headquartered banks. A German lender under Italian control—precisely the scenario EDIS sceptics have long invoked—now makes that political argument harder to sustain, while simultaneously making the case for a common scheme more urgent.
The legislative moment
The European Parliament adopted the Crisis Management and Deposit Insurance (CMDI) reform package on 26 March 2026. The package — Directive (EU) 2026/806 and Regulation (EU) 2026/808 — widens the use of national deposit-guarantee funds and lowers the threshold for triggering resolution. Publication in the Official Journal is expected in the fourth quarter of 2026.
There shouldn’t be any home and host within the banking union. — Andrea Enria, ex-ECB’s Supervisory Board head
The UniCredit-Commerzbank deal will be the first major test of that framework. If post-merger restructuring triggers resolution proceedings, the amended public-interest assessment and the expanded Single Resolution Fund backstop will be applied for the first time. The outcome could set binding precedent for how national deposit-guarantee schemes and the SRF interact in future cross-border cases.
Competition policy adds a further layer. The European Commission’s draft Merger Guidelines, currently under consultation, emphasise dynamic efficiency and cross-market effects. UniCredit-Commerzbank is likely to become the flagship case under the revised framework, setting precedents for market-share thresholds and remedy design. A DG COMP and OECD conference on modernising merger control is scheduled for September 2026, with the deal widely expected to feature on the agenda.
What a combined bank would mean
For UniCredit, the prize is Commerzbank’s deep relationships with Germany’s Mittelstand, i.e., the mid-sized manufacturers that form the backbone of Europe’s largest economy. UniCredit already operates in Germany through its HypoVereinsbank subsidiary. A successful merger would create a genuinely pan-European retail and corporate bank, operating under a single EU passport and rationalising trading books across borders.
Andrea Enria, former chair of the ECB’s Supervisory Board, put the supervisory logic plainly: “There shouldn’t be any home and host within the banking union.” That principle has long been aspirational. The UniCredit-Commerzbank saga will determine whether it is becoming real.
