ECB Confronts Berlin Over Commerzbank

ECB vice-president Luis de Guindos has said aloud what many in Europe have been thinking. In a Financial Times interview, he said it is "very difficult for governments to claim they support the Savings and Investment Union and then say: 'No, we are against this specific transaction.'"

The transaction is UniCredit's bid for Commerzbank. The government is Germany's. The point is larger than one bank: the EU's biggest member state is being challenged by a senior European Central Bank official over whether it believes in the single market when control of a national financial institution is at stake.

UniCredit already controls 38.87% of Commerzbank through direct shares, swaps and derivatives (Corriere della Sera, Ad Hoc News). On May 18, Commerzbank's board rejected the all-share offer, saying it was too low and too vague. The German government holds a 12% blocking minority and is searching for a way to stop the deal. The exchange offer remains open until June 16.

For Malta, the argument is familiar. Small member states are often told that open markets, banking union and capital market integration are the price of EU membership. The Commerzbank case shows the other side of that bargain: when a large country's own bank becomes the target, national control suddenly becomes a principle.

Berlin Can't Find a Legal Lever

Germany does not have the legal authority to block the deal directly. The ECB, which supervises eurozone banks, took over that role from national regulators in 2014. German antitrust regulators are the last formal hurdle, but the merger does not obviously breach competition thresholds.

Berlin considered buying a larger stake through KfW, its state-owned development bank, at a cost of roughly €5 billion. The Finance Ministry denied the plan. The far-right AfD has pushed Chancellor Friedrich Merz to use foreign investment screening law and declare Commerzbank strategic infrastructure.

That path is constitutionally fragile and would almost certainly provoke EU legal action. Spain is already facing infringement proceedings after Madrid imposed restrictions on the domestic BBVA-Sabadell merger (Ainvest).

Who Loses Their Job

Commerzbank serves roughly 24,000 corporate client groups and handles 30% of German foreign trade. The union ver.di estimates up to 15,000 jobs could go, mainly in Frankfurt and Munich. The works council says the figure could reach 23,000. UniCredit has made no public employment commitments.

There is a precedent. When UniCredit bought HypoVereinsbank in 2005, it cut roughly 9,000 jobs, but kept the brand and maintained lending to small and mid-sized firms through a standalone German operation. The feared retreat from local business did not happen.

Commerzbank, however, is more deeply wired into Germany's economic machinery. That is why unions are pushing harder this time.

The deal also reaches Poland, where Commerzbank owns 69.1% of mBank, the country's fifth-largest bank (Pb.pl). UniCredit already operates there, so regulators will have to assess the concentration that would result.

Every Capital Protects Its Own

European capitals defend their banks while speaking the language of openness. France recently strengthened its regulator's power to block bank M&A while championing a European capital markets union. Le Monde describes the whole integration project as an "Arlésienne" — always promised, never delivered.

The cost is visible in the numbers. Europe's top 25 banks combined are worth roughly what America's top four are worth alone. The ECB estimates the green transition requires €1.2 trillion in financing per year through 2030. No European bank locked inside its home market can finance at that scale.

Eurogroup president Kyriakos Pierrakakis put it plainly: "We need European champions, not national champions."

Institutional fund managers now have until June 16 to decide whether to tender their shares. Germany's response will matter well beyond Frankfurt. It will tell the market whether cross-border banking in Europe is an actual project or another EU promise that works only until a national champion is on the table.
