The Financial Stability Board (FSB) hosted a Modernisation Symposium on 9 June 2026 in Basel, bringing together representatives of authorities, academia, and industry to discuss methods and challenges of regulatory and supervisory modernisation. The event was part of the FSB’s work to promote well-aligned modernisation efforts and support members in making regulation and supervision more effective. Key discussions during the symposium focused on the drivers of change in regulatory and supervisory frameworks, the use of cost-benefit analysis, and tailoring/proportionality in regulatory and supervisory processes. Participants explored challenges such as addressing technological advancements, and ensuring a level playing field across jurisdictions. The insights shared during the event will contribute to a report that the FSB will submit to the G20 in October this year.
