The International Association of Insurance Supervisors (IAIS) published its September newsletter with a set of operational and standards-setting updates, led by the relaunch of its Insurance Core Principles (ICPs) Self-Assessment Tool and an updated register of Internationally Active Insurance Groups (IAIGs) under the Common Framework for Supervision of IAIGs (ComFrame). It also outlined priorities across financial stability monitoring and the agenda for the IAIS Annual Conference and related meetings in Tirana, Albania in November 2025. Previously hosted by the Access to Insurance Initiative, the ICP Self-Assessment Tool has been moved to the IAIS website with improved usability and security. The tool enables supervisors to complete ICP-by-ICP questionnaires using scoring criteria aligned with the IAIS Peer Review Process methodology, generating automated and non-binding results based solely on user responses and linking to peer review aggregate reports for comparative learning. The IAIG register now includes 61 IAIGs. On financial stability work, the newsletter reiterated that the IAIS Global Monitoring Exercise collects data from the 60 largest international insurance groups and sector-wide monitoring data covering over 90% of global written premiums, and noted ongoing enhancements including additional ancillary risk indicators spanning credit risk, derivatives, reinsurance, mark-to-model assets and liquidity metrics. The IAIS expects to publish by end-2025 a final Issues Paper on structural shifts in the life insurance sector, reflecting input to a consultation launched in March, and to finalise updates to the individual insurer monitoring assessment methodology for the 2026–2028 cycle after a June consultation. It also plans further consultations in 2025 on updated supervisory application papers, including on recovery and resolution planning, and the Tirana conference on 13–14 November will include sessions on insurers’ growing investment in private credit and the increasing use of cross-border asset-intensive reinsurance.
