ECB Greenlights UniCredit’s Capital Calculation Method for Commerzbank Bid

On September 8, 2026, the European Central Bank (ECB) approved UniCredit’s request to use the "Danish compromise" method for calculating its capital ratios. This regulatory decision is critical for UniCredit’s ongoing acquisition strategy, as it allows the bank to optimize its capital position while pursuing the full takeover of Commerzbank. Despite this positive regulatory development, UniCredit shares experienced some volatility as investors weighed the implications for integration costs and future capital requirements.

ECB Report Highlights European Bank Profitability Amidst Fragmentation

In a recent statement published on September 8, 2026, the ECB noted that European banks have significantly improved profitability since the pandemic, with cost-to-income ratios narrowing the gap with US peers. However, the report emphasized that market fragmentation remains a key challenge, limiting the efficiency of cross-border banking activities. The ECB stressed that while individual bank health has improved, structural reforms are needed to enhance the competitiveness of the European banking sector as a whole.

Japanese Megabanks Report Record Profits on Rate Hikes and Buybacks

Japanese megabanks, including Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, and Mizuho Financial Group, reported record net profits for the fiscal year ending March 2026, totaling approximately ¥5.3 trillion (approx. $35 billion). This performance, driven by rising domestic interest rates which widened net interest margins, marks the first time the combined profits exceeded ¥5 trillion. Analysts note that aggressive share buybacks and reduced cross-shareholdings have further supported stock performance, although recent profit-taking occurred in early September due to stabilizing long-term interest rates.

Commerzbank Launches New Share Buyback Program Ahead of Critical Date

Commerzbank initiated a new share buyback program worth up to €1.2 billion, set to run until February 2027. This move is seen as a defensive strategy by management to support the share price amid the ongoing takeover battle with UniCredit. The buyback coincides with a key date on September 14, 2026, when stakeholders will assess whether Commerzbank can maintain its independence or if the merger process will accelerate towards completion in Q4 2026.

Local view

German financial media outlets such as boerse.de and finanzen.at are closely monitoring the interplay between Commerzbank’s share buybacks and UniCredit’s regulatory wins. Local analysts suggest that the "Danish compromise" approval is a technical victory for UniCredit but does not guarantee immediate shareholder acceptance of the takeover offer. In Japan, media coverage from Matsui Securities highlights the historic nature of the megabanks' profit levels, framing them as a sign of successful normalization away from decades of ultra-low rates.

Context & numbers

• Commerzbank Buyback: Up to €1.2 billion until February 2027.
