Aon stock gains as 2027 treaty capacity rises to 35%

- The Aon Client Treaty will support eligible insurance and facultative reinsurance placements from January 2027.
- Clients may receive a dividend on eligible placements where local law and the facility rules permit.
- The expansion targets larger and more complex individual risks as demand for facultative capacity grows.
Aon has renewed its Aon Client Treaty for 2027, increasing committed co-insurance capacity for eligible placements from January 1. Insurance Asia reported the expansion on Monday, November 9, saying the facility will give clients access to a larger share of insurance and reinsurance risks placed through Aon's Global Broking Centre and Reinsurance Solutions.
The facility is led by QBE and backed by Lloyd's syndicates. Clients can use the capacity on the same terms and pricing as the lead placement, subject to client agreement, eligibility rules, local laws and Aon's conflicts of interest framework.
Broader access to committed capacity
The arrangement is particularly relevant to facultative reinsurance, which covers individual risks that can be too large or complex for standard treaty programmes. Insurance Asia quoted Aon Risk Capital CEO Joe Peiser as saying the increase should improve efficiency and give clients greater confidence when placing risks.
Helene Madell, CEO of Aon's Global Broking Centre, said facultative reinsurance had become one of the facility's key growth areas. Since its launch in 2016, ACT has placed more than 5 billion US dollars in gross written premiums, according to Insurance Asia.
The expanded facility also retains the ACT Client Dividend. Eligible clients may receive the dividend on the portion supported by ACT where local law and the facility's eligibility requirements allow it. The arrangement therefore combines pre-committed capacity with a potential economic benefit for participating clients, while leaving the final placement decision with each client.
Reinsurance demand remains central
For Aon, the renewal extends its role beyond traditional broking by linking client placements with committed risk capital. The focus on large infrastructure, energy, technology and other complex exposures gives the facility a route to grow as insurers seek capacity for risks that are difficult to place through conventional programmes.
The development follows Aon's wider push to connect broking, reinsurance and digital placement capabilities. It is an operating expansion rather than a change to the company's earnings guidance, and the available capacity remains limited to eligible business under the stated terms.
