CHICAGO, May 19, 2025 - Aon plc (NYSE: AON), a leading global professional services firm, today announced an expansion of its collaboration with risk data, analytics and technology leader, Moody’s Insurance Solutions, that will reduce latency and accumulation risk for casualty re/insurers, while continuing to drive product innovation in the casualty re/insurance sector. 

Following its initial success in casualty reinsurance, the Aon/Moody’s collaboration will now expand into commercial risk, delivering insights around climate casualty and other emerging risks, risk mitigation strategies, and excess casualty named-peril products to commercial insurance buyers. 

As dynamics in areas including social inflation and litigation finance create new emerging risks with increased frequency and severity, named-peril products can help drive efficient risk transfer and insurance premium growth, as well as better casualty protection for clients at risk-appropriate pricing. This reduces uncertainty around exclusions, insufficient limits and coverage disputes.

The expanded collaboration between Aon and Moody’s combines the advanced technology of Moody’s Casualty unit – which identifies and models more than 300 emerging risk perils – with Aon’s extensive global relationships both in the traditional and alternative capital sectors. This synergy facilitates the more efficient allocation of capital to risk in order to shape better business decisions for Aon clients when managing their casualty portfolios. 

Amanda Lyons, global product leader for Reinsurance Solutions at Aon, said: "Traditional casualty clash solutions have struggled to provide capital-efficient coverage. Our collaboration with Moody’s is now creating products that better reflect exposures and offer more attractive pricing for both commercial risk and reinsurance. This helps businesses make better decisions and supports reinsurance clients and original buyers in confidently pursuing growth strategies."

Robert Reville, head of casualty market development for Moody’s, said: “The increasingly volatile liability environment challenges the entire value chain of insurance – from the original buyers to their insurers and reinsurers. In this environment, we expect named-peril products to lead to the emergence of a casualty catastrophe market. We are delighted to work with Aon to drive such innovation in the re/insurance market.”
