ECB Rebukes Berlin Over Commerzbank

Luis de Guindos said aloud what many in Europe have been thinking. The ECB vice-president told the Financial Times 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 charge, coming from the European Central Bank, is that Berlin wants an integrated European market in theory, but a protected national bank in practice.

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, arguing that it was too low and too vague. The German state still holds a 12% blocking minority and is searching for a way to stop the deal. The exchange offer remains open until June 16.

The row matters beyond Frankfurt and Milan. It exposes the old weakness in European banking integration: every capital supports it until the bank on the table is its own.

Berlin Can't Find a Legal Lever

Germany's problem is that it no longer has a clean legal route to block the deal. Since 2014, the ECB has directly supervised eurozone banks, taking that power away from national regulators. German competition authorities are the last formal hurdle, but the merger does not obviously breach antitrust thresholds.

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

That would be a shaky route. It is constitutionally fragile and would almost certainly draw EU legal action. Spain is already facing infringement proceedings after Madrid placed restrictions on the domestic BBVA-Sabadell merger (Ainvest).

For Irish readers, the mechanism is familiar enough. The single market works only when national governments accept that rules they like in general may bite them in particular. Berlin helped build that system. It is now discovering how little room it leaves for political discretion.

Who Loses Their Job

Commerzbank is not just another listed bank. It serves about 24,000 corporate client groups and handles 30% of German foreign trade. That is why the political resistance is so fierce.

The union ver.di estimates up to 15,000 jobs could go, mainly in Frankfurt and Munich. The works council says the number could reach 23,000. UniCredit has made no public employment commitments.

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

Commerzbank is different because it is deeper inside Germany's economic machinery. It is the bank of Mittelstand firms, exporters and supply chains. That is why unions are pushing harder this time, and why the German government is treating the bid as more than a shareholder question.

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

Every Capital Protects Its Own

The uncomfortable truth is that Germany is hardly alone. European governments defend national banks while speaking the language of openness. France recently strengthened its regulator's power to block bank M&A while still backing a European capital markets union. Le Monde called the wider integration project an "Arlésienne" — always promised, never delivered.

The price of fragmentation is not abstract. Europe's top 25 banks together are worth roughly what America's top four are worth on their own. The ECB estimates that the green transition needs €1.2 trillion in financing per year through 2030. A bank trapped inside one home market cannot underwrite investment at that scale.

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

The shareholders now have until June 16 to decide whether to tender their shares. But the larger audience is other European banks watching to see whether a cross-border deal can survive contact with national politics. Germany's answer will shape whether the next attempt is made at all.
