Aon and Blackstone Launch New Lloyd’s Reinsurance Syndicate
Aon and funds managed by Blackstone have announced the launch of Cortina syndicate 1956, a new Lloyd’s syndicate designed to provide dedicated, multi-year reinsurance capacity and bring additional long-term institutional capital into the market.
The new syndicate will operate within Lloyd’s, with QBE acting as Managing Agent and responsible for its underwriting and governance. Subject to final Lloyd’s approval, Cortina is expected to begin underwriting from 1 January 2027.
The new model is intended to broaden the capital available to reinsurance clients while providing a stable source of capacity across renewal cycles. For participating clients, Cortina will write 3% of eligible property catastrophe excess-of-loss treaties and 5% of other eligible treaties arranged by Aon.
Rather than replacing the role of traditional reinsurers, Cortina will operate through a conventional lead/follow model, following the terms and claims decisions established by lead reinsurers on each placement.
The structure also has a distinctive client element. Participating clients will benefit from a dividend linked to Cortina’s share of their reinsurance programmes, passing some of the economic efficiencies of the model back to cedents.
The initiative brings together Blackstone’s long-term institutional capital, QBE’s underwriting expertise and Lloyd’s’ market infrastructure, including the London Bridge 2 framework. It represents another example of how new sources of capital and operating models are being used to expand the market’s capacity to take risk.
As risks increase in scale and complexity, structures such as Cortina could play a growing role in connecting alternative sources of capital with established insurance and reinsurance expertise.
