When Commerzbank's deputy supervisory board chair told UniCredit CEO Andrea Orcel to "sell his shares, take his profits and go home" last week, he exposed Europe's fundamental banking crisis. This wasn't merely corporate resistance to a hostile takeover, but it was the latest manifestation of the Fragmentation Trap that is systematically destroying European banking competitiveness and preventing the continent from building financial institutions capable of responding to the next crisis.

Europe's banking fragmentation crisis is evident in comparison to its American counterparts. For example, consider JPMorgan Chase, which commands $4.0 trillion in assets, making it 37% larger than HSBC, Europe's largest bank, which has $3.7 trillion in assets. This size disadvantage compounds across the sector, as the top five US banks control 50% of American banking assets. In contrast, European banking remains fragmented across 27 national markets, characterized by incompatible regulations, tax systems, and political interference.
