Banking Scale Capital buffers were strengthened. Supervision became more intrusive. Risk management was tightened. The European banking system became safer, more resilient and better pre- pared to absorb shocks. These were important achievements. But regulatory systems, like financial markets, produce consequences be- yond their original objectives. Europe spent much of the past decade building safeguards against the last crisis while the United States moved more rapidly into a new cycle of economic expansion, technology investment and capital-market growth. The result is not that prudential dis- cipline was wrong. The more difficult conclusion is that measures designed to strengthen re- silience can, if combined with slow growth and fragmented markets, im- pose long-term competitive costs. This is where the European debate has now become more complex. The question is no longer whether banks should be well capitalized. Of course they should. The real issue is whether capital re- quirements, market structure and regulatory complexity have together reached a point where the pursuit of stability begins to affect the ability of banks to compete, invest and lend. EUROPE’S UNFINISHED BANKING MARKET Regulation, however, explains only part of the problem. Europe remains financially frag- mented. Despite decades of economic inte- gration, its banking market does not yet operate with the seamless scale of the United States. National legal structures, regulatory preferences, political sensitivities and differing market conditions continue to complicate cross-border consoli- dation. The extended process surrounding potential consolidation involving UniCredit and Commerzbank illus- trates the difficulty. A merger between large European banks is rarely treated simply as a commercial transaction. It can quickly become a discussion about employment, national economic in- terests, regulatory authority and the control of strategic financial institu- tions. The consequence is that Europe has many large banks but remarkably few institutions that can truly be de- scribed as pan-European. That distinction increasingly matters. Banking has become a scale busi- ness. Technology investment, cybersecu- rity, compliance infrastructure, data management and artificial intelli- gence require enormous expendi- ture. Larger institutions can distribute those costs across wider customer bases. Scale also creates strategic flexibility. A bank with a stronger valuation and broader market reach can invest through economic cycles when weaker institutions are forced to pre- serve capital. The danger is therefore not simply that European banks are smaller in market value today. It is that the gap could become self- reinforcing. THE COMPOUNDING EFFECT Consider the difference between two financial cycles. In one system, stronger economic growth generates higher corporate profits and greater financial activity. Banks benefit from that expansion. Higher profitability improves valua- tions. Strong valuations reduce the cost of capital and create acquisition currency. Banks can then invest more aggressively in technology, distribu- tion and new businesses. Those in- vestments strengthen efficiency and profitability further. This becomes a compounding ma- chine. In another system, weaker economic growth depresses revenue opportuni- ties. Fragmentation raises structural costs. Conservative capital require- ments limit financial flexibility. Lower profitability restrains valua- tions. Lower valuations make acqui- sitions and equity raising less attractive. Banks then have fewer strategic resources with which to ad- dress the very weaknesses holding them back. This does not mean that every Euro- pean bank is trapped in such a cycle, nor that every US institution benefits equally. But it helps explain why the market- capitalization comparison matters. It is not simply a snapshot of where the two banking systems stand. It can influence how far apart they may stand tomorrow. REGULATION RETURNS TO THE CENTRE The widening transatlantic gap has therefore intensified scrutiny of reg- ulation. Research by Oliver Wyman and Au- tonomous has estimated that the Eu- ropean Central Bank’s more conservative supervisory approach reduces the return on equity of Euro- pean banks by roughly one percent- age point relative to comparable US institutions. That difference is important, but it is the BANKING EXECUTIVE 42 ISSUE 212 AUGUST 2026
