UniCredit plans to raise Commerzbank stake to 30% ahead of possible takeover

UniCredit has announced it will increase its stake in Commerzbank to 30%, a threshold that in European banking M&A typically signals that a full acquisition bid is being prepared rather than ruled out. The Italian bank has been building its position in Germany's second-largest bank incrementally since late 2024, and this latest move puts it close to the point where German regulators and the federal government will need to take a formal position on whether a cross-border takeover will be allowed to proceed.

How UniCredit got here and what 30% actually means

UniCredit first disclosed a significant Commerzbank stake in September 2024, when it revealed it had acquired roughly 9 percent of the German bank's shares, partly through derivatives. That announcement immediately drew scrutiny in Berlin because it came without prior coordination with the German government, which still holds approximately 12 percent of Commerzbank following a 2008 bailout. UniCredit's CEO Andrea Orcel has since described the stake as a strategic investment while being careful not to formally declare a takeover intention, which would trigger mandatory bid rules under EU regulations.

Raising the stake to 30 percent changes the dynamic considerably. Under German takeover law, crossing 30 percent ownership requires either launching a mandatory public offer for all remaining shares or obtaining a regulatory exemption. UniCredit will need approval from BaFin, Germany's financial regulator, and the European Central Bank's banking supervision arm before completing the increase. Neither body has signaled how it will respond.

Germany's position and why it is complicated

The German government's relationship with Commerzbank is not straightforward. Berlin acquired its stake during the 2008 financial crisis when Commerzbank required a state rescue and has been gradually reducing its position since 2013. By the time UniCredit began its accumulation, Germany had already sold down to around 12 percent and had signaled it intended to exit entirely. That exit strategy is now complicated by the prospect of a foreign bank taking control of one of Germany's most systemically important financial institutions.

Chancellor Olaf Scholz's government publicly opposed UniCredit's initial stake accumulation in 2024, with Finance Minister Christian Lindner describing it as an unfriendly move. The new German government formed after the February 2026 elections has not yet taken a formal public position on the expanded stake, though CDU-led administrations have historically been more open to private sector consolidation than the SPD. That political shift in Berlin could make regulatory approval more attainable than it would have been six months ago.

What a full UniCredit-Commerzbank merger would create

A completed acquisition would produce one of the largest banks in Europe by total assets. UniCredit reported total assets of approximately 1.26 trillion euros at the end of 2024. Commerzbank's balance sheet sits at around 530 billion euros. A combined entity would exceed 1.7 trillion euros in assets, putting it in the same tier as BNP Paribas and Santander and well ahead of Deutsche Bank, Germany's largest bank, which reported assets of around 1.3 trillion euros.

From a commercial banking perspective, the combination would give UniCredit a large retail and corporate banking presence in Germany's Mittelstand, the network of mid-sized industrial companies that form the backbone of the German economy. Commerzbank has long specialized in serving those businesses. UniCredit's existing German operations through HypoVereinsbank already give it some presence there, so the integration argument is about scale and customer overlap rather than entering a market cold.

Regulatory timeline and what comes next

UniCredit must clear ECB approval for the 30 percent stake increase before completing the transaction. The ECB's supervisory review process for significant acquisitions in European banking typically runs three to four months after a complete application is submitted. BaFin's parallel review adds another layer of timing uncertainty. If both regulators approve the stake increase without conditions, UniCredit would then face a decision on whether to launch a formal mandatory offer or seek an exemption while continuing to hold just under the full takeover threshold.

Commerzbank's share price rose approximately 4 percent on the day of UniCredit's announcement, which suggests markets are pricing in a meaningful probability of a full bid at a premium to the current trading price. UniCredit has not set a timeline for a formal takeover offer, and Orcel has consistently said the bank will only proceed if the financial terms work. Commerzbank's board has not publicly endorsed the approach, and its supervisory board chair Jens Weidmann, the former president of the Bundesbank, has previously described UniCredit's advances as unwelcome.
