AON Securities

Aon Securities structures and places insurance-linked securities and alternative risk transfer instruments, primarily catastrophe bonds, collateralized reinsurance sidecars, and insurance-linked notes. It acts as an intermediary between sponsors seeking to transfer peak natural catastrophe risk and institutional investors seeking uncorrelated returns. The unit functions as a blend of reinsurance brokerage and structured finance execution, earning placement and advisory fees rather than managing a balance sheet.

Aon Securities is a wholly owned subsidiary and operating unit of Aon plc, the London-headquartered global professional services firm traded on the New York Stock Exchange as AON. It sits within Aon Reinsurance Solutions, which provides treaty and facultative reinsurance brokerage. This parentage supplies the ILS unit with proprietary catastrophe analytics, a broad sponsor client base, and the placing infrastructure of the world's second-largest insurance broker.

Institutional investors including dedicated ILS funds, pension plans, sovereign wealth funds, and multi-strategy asset managers participate in its catastrophe bond and sidecar placements. The investor base is global, with concentration in U.S. and European institutional markets. Aon Securities does not manage pooled funds as an investment manager; it arranges deals that investors access through their own allocations.

Aon Securities has structured catastrophe bonds for corporate and sovereign sponsors across U.S. hurricane, European windstorm, Japanese earthquake, and Australian cyclone perils. Its historical transactions span the entire modern cat bond era dating to the 1990s. The unit publishes an annual ILS market report that tracks issuance volumes and market trends, functioning as a widely cited record of market activity (per Aon Securities, public record).

No. Aon Securities does not operate an ILS fund or directly manage investor capital. It earns placement, structuring, and advisory fees by arranging transactions between risk sponsors and capital markets investors. This separates it from ILS fund managers and gives it a structurally different incentive set as an intermediary rather than an asset gatherer.

The unit operates from offices in Chicago, New York, London, and Bermuda, with deal coverage extending to key reinsurance markets including Europe, Japan, and Australia. Its geographic footprint mirrors the catastrophe risk corridors where ILS demand is most concentrated.

Risk flows from Aon Reinsurance Solutions' global brokerage client base of insurers, reinsurers, and sovereign entities. The unit's sourcing advantage derives from Aon plc's position as one of the world's largest reinsurance intermediaries; treaty clients and analytics are already within the parent organization, allowing Aon Securities to structure capital markets solutions without an external origination effort.
