The Financial Stability Board hosted a regulatory and supervisory modernisation symposium in Basel, bringing together representatives of authorities, academia and industry to discuss methods and challenges in updating regulatory and supervisory frameworks. The event formed part of the FSB’s work to promote aligned modernisation efforts and support members in making regulation and supervision more effective. Discussions focused on the drivers of change in regulatory and supervisory frameworks, the use of cost-benefit analysis, and tailoring and proportionality in regulatory and supervisory processes. Participants also examined how to address technological advances and maintain a level playing field across jurisdictions. Insights from the symposium will feed into a report the FSB plans to submit to the Group of Twenty in October 2026.
