Commerzbank at a Crossroads: Technical Support Holds as Takeover Tensions Boil Over

Commerzbank stock hovers above critical 50-day moving average amid UniCredit's contested takeover bid, BaFin probe, and diverging momentum signals.

The high-stakes battle for Commerzbank is testing more than just regulatory boundaries. While UniCredit’s surprise disclosure of a 37.68% stake has triggered a BaFin probe and a war of words between the two banks, the share price is quietly anchoring itself above a critical technical floor. At 36.60 euros, the stock sits roughly 3.7% above its 50-day moving average of 35.30 euros — a level that has become the defining support in a market now pricing in months of uncertainty.

UniCredit announced on 9 June that its total exposure to Commerzbank, including physically settled derivatives, gives it potential control of 40.9% of the lender. The Italian giant said its exchange offer — 0.485 UniCredit shares for each Commerzbank share — drew tenders representing an additional 10.91% of the German bank. Frankfurt’s management immediately pushed back, arguing that the true acceptance rate stands at just 7.85%, with retail investors accounting for a mere 0.05% of that. The bank suspects tactical positioning by investment banks and business partners aligned with UniCredit and has asked BaFin to examine both the disclosures and the Italian group’s communications. UniCredit has denied any wrongdoing.

The technical picture offers a calmer counterpoint. The 50-day moving average at 35.30 euros sits comfortably above the 200-day average, forming a classic Golden Cross that underpins the long-term uptrend from the July 2025 low of 26.70 euros. The stock is roughly 4% below its 52-week peak of 38.15 euros, hit on 1 June, and has been consolidating ever since. Weekly losses of 1.83% suggest a moderate cooling rather than a trend reversal. Should the price break above 38.15 on a sustained basis, fresh buy signals would open the door to uncharted territory.

Momentum, however, is sending a quieter caution. The 14-day Relative Strength Index sits at 52.4 — neutral territory — but is diverging negatively from price action. While the stock remains near its high, momentum has already turned lower, raising the risk of a short-term pullback. Annualised 30-day volatility of nearly 29% adds to the sense of unease, amplified by the ongoing takeover saga. That turbulence is reflected elsewhere: the volume of stock lending has exploded by 1,190% since the start of the year, a sign that professional investors are positioning for a prolonged contest rather than a quick resolution.

The exchange offer itself runs until 16 June, with a possible extension to 3 July. Commerzbank’s board and the German government remain opposed to a full takeover, and the low retail take-up underscores the resistance among smaller shareholders. The implied value of the swap — roughly 34.60 euros per Commerzbank share based on current UniCredit prices — leaves a gap of about two euros to the trading price, suggesting the market sees at least some chance that the bid will be sweetened or that competition emerges.

In essence, the share price is caught between two forces. Above, the 38.15 euro resistance caps near-term optimism. Below, the 35.30 euro moving average provides a safety net that has so far held firm in the face of a regulatory dispute and a record surge in stock lending. Until the BaFin review concludes or the offer deadline passes, Commerzbank’s technical floor may be the only anchor in a storm of claims and counterclaims.
