Aon has renewed its Aon Client Treaty facility for 2027, expanding the committed reinsurance capacity available for eligible placements from January 1. Insurance Journal reported the announcement on November 5, citing the broker and statements from Aon executives.

Under the renewed arrangement, eligible business placed through Aon's Global Broking Centre and facultative reinsurance placed by Aon's Reinsurance Solutions business can access a larger share of co-insurance. The facility is led by QBE and backed by Lloyd's syndicates. Client access remains subject to agreement, eligibility criteria, local law and regulation.

Capacity targets complex risks

The expansion is particularly relevant to facultative reinsurance, where insurers seek capacity for individual risks that may be too large or complex for their usual treaty programs. Insurance Journal said the facility has supported facultative reinsurance since late 2025 and has placed more than 5 billion US dollars of gross written premium since its launch in 2016.

Where permitted and applicable, the ACT Client Dividend will apply to the eligible share. Aon said the arrangement is intended to improve access to risk capital as client exposures become more complex and interconnected. The company also links the facility with its digital placement and claims capabilities.

Aon stock traded at 301.55 euros on Lang & Schwarz at 10:06 CET on Monday, November 9, 2026.

Investors are likely to focus on whether the expanded capacity supports growth in Aon's broking and reinsurance activities while the company continues to integrate its wider Risk Capital strategy. The treaty announcement does not by itself establish a change in earnings guidance.
