The European Union's aggressive response to the global financial crisis has prevented financial meltdown, but the continent's banking industry remains very fragile. Experts estimate coming losses in excess of $500 billion, with very little written down so far. These losses plus the problems in Eastern Europe portend widespread cross-border bank insolvencies. Traditional banking (in corporate finance and household savings) remains predominant in the European economies, so healing the banking system is crucial for sustained recovery in Europe. Lingering banking fragility would result in constant disruption or misallocation of bank credit and hinder returns to savers, thus depressing investment and consumption. Ongoing fragility will also harm European trend productivity growth by skipping some investment and R&D cycles, misallocating capital to lower-return projects, and wasting human capital by consigning some workers to long-term unemployment.
It will take time and political will to create an EU banking supervisory architecture, but Europe cannot afford to wait. Posen and Véron recommend that Europe engage in system-wide "triage" of major banks on the continent by capital position, leading to public restructuring of the weakest ones. They propose that relevant countries jointly create a temporary supranational agency or Treuhand to implement the triage process, catalyze recapitalizations, and manage any distressed assets that would fall into public ownership. Such a trustee would avoid both harmful races to the bottom within Europe by national supervisors and fiscal transfers between European states for bailouts.
