The European Banking Authority has opened a call for papers for its 15th Policy Research Workshop, themed “Efficient and Proportionate Regulation for a Competitive Financial Sector”, which will be held as a hybrid event in Paris on 18-19 November 2026. The workshop is positioned as a forum for policy-oriented, preferably empirical, research on how regulatory frameworks can be made more efficient and proportionate while supporting competitiveness, resilience and integration. Submissions are invited on competitiveness and efficiency in the prudential rulebook without undermining resilience, the impacts of efficiency and proportionality, and supervisory approaches to competition, innovation, market entry and cross-border growth, including new areas under financial supervision such as digital interlinkages, crypto-bank transmission channels, decentralised finance, and the adoption of artificial intelligence and machine learning. The call also covers proportionate integration of ESG risks into banks’ governance, strategy and remuneration frameworks, and regulatory designs supporting harmonisation, supervisory convergence and deeper Single Market integration. Draft papers must be submitted by 19 June 2026, with contributors to be notified by mid-September 2026.
