The beginning of March 2026 marked the end of the second year of the National Association of Insurance Commissioners’ (NAIC) three-year Risk-Based Capital (RBC) Climate Interrogatory. The interrogatory requires insurers with exposure to two key perils, wildfires and hurricanes, to assess the climate impact on catastrophe exposure using climate-conditioned models.
Guy Carpenter, a Marsh business, guided insurers during the first two years of the interrogatory, helping clients navigate the requirement with practical analytics, regulator-ready reporting assistance, and science-based climate insights.
