Divergent global implementation of Basel 3: consequences for the EU banking sector and adequacy of the EU policy response​

Objectives

Objectives

This session aims to assess whether the European Union’s faithful and timely implementation of Basel III remains fit for purpose in a context of increasing global divergence. In a context of lukewarm growth, the EU has made the choice of a faithful application of the Basel III implementation. While the EU is proceeding with the full application of the CRR3/CRD6 package, other major jurisdictions — notably the United States, the United Kingdom, Switzerland and several Asian financial centres — are adopting differentiated approaches in terms of capital calibration, reliance on internal models, the use of output floors, stress tests and supervisory discretion. The discussion will explore whether these divergences reflect temporary sequencing differences or more structural shifts in prudential philosophy that could durably reshape the competitive landsape.

A central objective is to analyse the competitive implications of this fragmentation for European banks, both globally and within the EU single market.

Finally, the debate will consider the adequacy of the EU policy response. Should strict alignment with international standards remain the guiding principle in all circumstances, or should the EU consider more adaptive mechanisms if global convergence fails to materialise? Beyond the European dimension, the session will also reflect on the credibility and future role of international standard-setting bodies, at a time when globally agreed standards are increasingly endorsed in principle but implemented selectively in practice.

Points of discussion

1. Is the divergent global implementation of Basel III primarily a matter of timing and calibration, or does it reflect deeper and potentially lasting differences in prudential philosophy and risk-mitigation architecture across jurisdictions? 
2. Is the current EU policy response to divergent Basel III implementation adequate to safeguard financial stability while preserving the competitiveness of EU banks and their capacity to support the European economy?
