Aon and Blackstone funds launch Cortina Lloyd’s syndicate

Aon and Blackstone launch Cortina syndicate

Aon plc and funds managed by Blackstone announced the launch of Cortina syndicate 1956, a new Lloyd’s syndicate intended to provide dedicated, multi-year reinsurance capacity and broaden the capital available to clients. The announcement was made on November 6, 2026.

Cortina received Lloyd’s Council’s “in principle” approval on October 16, 2026, according to the announcement. It is continuing to work with Lloyd’s to complete the required “Making It Happen” actions before receiving permission to underwrite.

Underwriting planned from January 2027

Cortina intends to begin underwriting from January 1, 2027, subject to final Lloyd’s approval. The syndicate will follow a conventional “lead/follow” approach, writing three percent of eligible property catastrophe excess-of-loss treaties and five percent of all other eligible treaties arranged by Aon.

The syndicate will offer capacity on eligible treaties within a defined framework, providing participating clients with what the announcement described as a stable source of capacity across renewal cycles. Clients participating in Cortina will receive a dividend based on the syndicate’s share of their reinsurance programs, reflecting the structure’s intended operating efficiencies.

QBE to manage underwriting and governance

QBE will serve as Cortina’s managing agent, responsible for the syndicate’s underwriting and governance. The announcement said Cortina would provide clients with the financial security of a Lloyd’s syndicate, which carries an A+ financial strength rating, alongside QBE’s experience as a managing agent.

The syndicate’s terms and claims decisions will be set by the lead reinsurer on each placement, keeping underwriting expertise at the center of each program. Cortina is intended to complement traditional reinsurers rather than replace them.

What remains pending

The launch has been announced, but underwriting is not yet authorized. Cortina is still completing actions with Lloyd’s, and the planned January 1, 2027 start remains conditional on final approval. The reviewed reporting did not provide further details about the capital amount, client commitments or projected underwriting volume.
