The takeover battle for Commerzbank has taken a fresh turn, with the Italian banking watchdog throwing a costly new variable into UniCredit’s already complex equation. Banca d’Italia has classified the Milan-based lender as systemically important, triggering an additional capital buffer of 1.25% of risk-weighted assets since the start of 2026. That requirement eats into the financial firepower UniCredit needs to complete its ambitious German push.
Andrea Orcel’s bank already controls 42.5% of Commerzbank through a combination of directly held shares and derivatives. The tender offer for the remaining stock runs until July 3, 2026, with market participants expecting an initial tally a few days later. But every additional percentage point UniCredit acquires will now tie up more equity, as the regulator weighs the size and interconnectedness of the enlarged position. What began as a straightforward hostile bid is morphing into a regulatory calculus with no easy answers.
A German banking giant in the making
UniCredit’s ultimate ambition is to fold Commerzbank into its German subsidiary HypoVereinsbank. The combined entity would command roughly 8.5% of the German banking market, with management targeting as much as 14% in the lucrative Mittelstand segment. The plan would create a new heavyweight in corporate lending, squarely challenging domestic rivals.
Should investors sell immediately? Or is it worth buying Commerzbank?
On the regulatory front, the European Central Bank and competition authorities are reviewing the deal, a process expected to take between three and six months. A key milestone comes in the third quarter of 2026, when supervisors rule on the so-called “Danish Compromise” — a mechanism that determines how equity stakes are treated under capital adequacy rules. A favourable decision would substantially lower the capital drag from the combined holding, but it remains uncertain.
Stock shrugs off the noise
The shares have proven remarkably resilient amid the growing regulatory overhang. On Wednesday, Commerzbank traded at €37.68, a barely perceptible decline from the previous day’s close of €37.79. That puts the stock just 3% below its year-to-date high, with an annual gain of roughly 31%.
Technically, the trend remains firmly bullish. The price sits comfortably above both the 50-day moving average of €36.30 and the longer-term support line at €34.07. The relative strength index at 57.5 signals neutral territory, leaving room for further upside without being overbought. Investors are now positioning for the July 3 deadline, when the extended acceptance period ends and the final size of UniCredit’s stake becomes clear. Until then, every regulatory headline and supervisory decision will be scrutinised for its impact on the deal’s ultimate cost.
