The European Central Bank has given UniCredit the green light to cross the 30 percent threshold in Commerzbank and to continue raising its stake without a cap, removing the single most important regulatory obstacle to a full takeover of Germany's second-largest listed lender.
The authorisation, announced by the Milan-based bank, means UniCredit can now proceed with the remaining approvals and conditions attached to its offer. Those steps are expected to be completed towards the end of the year, at which point UniCredit would hold roughly half of Commerzbank's voting rights and be in a position to consolidate the Frankfurt institution.
A milestone for European banking integration
UniCredit described the ECB's decision as a turning point in the transaction, saying it reflected the supervisor's positive assessment of the deal and its confidence in the Italian group's capital strength and standing in the European banking sector. The bank, headquartered at Piazza Gae Aulenti in Milan, has argued that a cross-border combination would create a more resilient institution capable of competing with larger global rivals.
The approval is significant beyond the two banks involved. Cross-border mergers in European banking have long been rare, held back by fragmented supervision, political resistance and the absence of a fully fledged banking union. A successful UniCredit-Commerzbank tie-up would test whether the sector can consolidate across national lines — a goal repeatedly endorsed in Brussels and Frankfurt but seldom realised in practice.
UniCredit has already moved to streamline its footprint elsewhere. Earlier this year it secured approval from Russian authorities to divest part of its Russian business, a step that reduces the geopolitical exposure its supervisors weigh when assessing large acquisitions.
Political headwinds in Berlin
The path to control has not been smooth. Commerzbank's management and German trade unions have opposed the approach, warning about job losses and the risk of losing a nationally important lender. Politicians in Berlin, including figures in the governing coalition, have voiced reservations about a foreign takeover of a bank that plays a central role in financing the Mittelstand — Germany's small and medium-sized industrial backbone.
The ECB's decision does not settle those political questions, but it shifts the balance. Once the supervisory hurdle is cleared, the main remaining obstacles are commercial and political rather than regulatory. UniCredit has said it will proceed cautiously, and any integration would unfold over several years rather than overnight.
The timing also matters for the wider European agenda. Policymakers in Brussels have spent years arguing that the continent's banks need scale to fund the green transition, defence spending and digital investment. A deal of this size would be the most concrete test yet of whether that argument can overcome national sensitivities.
What happens next
- UniCredit will complete the remaining regulatory steps and conditions attached to its offer by the end of the year.
- At that point it expects to hold around 50 percent of Commerzbank's voting rights and to take control.
- Integration would be gradual, with German political opposition likely to persist.
- The outcome will shape expectations for future cross-border bank mergers across the EU.
For now, the ECB's ruling gives UniCredit the legal room it needs. Whether it can translate that into a functioning combined bank — and persuade Berlin that the result serves German interests — is the harder question, and one that will define European banking consolidation for years to come.
