The Financial Stability Board (FSB) has published a letter from its chair, Klaas Knot, to G20 Finance Ministers and Central Bank Governors ahead of the meeting on 23–24 April 2025. The letter emphasises the importance of robust surveillance, proactive policymaking, and international coordination in response to recent financial market turmoil. It highlights the vital role of non-bank financial entities and stresses the need for enhanced regulation, continued reform, and international cooperation amid heightened market volatility and geopolitical risks. The letter also outlines efforts to strengthen non-bank financial intermediation, and the finalisation of recommendations to address leverage-related risks due in July 2025, and addresses cyber risks alongside improvements in cross-border payments. Knot calls for continued commitment to implementing international reforms to preserve financial stability and avoid fragmentation in an evolving risk environment.
