Sirius International Managing Agency Limited

Sirius International Managing Agency Limited was established in 1985 as a vehicle for underwriting insurance and reinsurance risks from its base in Bermuda. The firm is part of the broader SiriusPoint family, which emerged from the 2021 merger of Sirius International Insurance Group and Third Point Re. Wealth origin relates to insurance underwriting capital, not a specific family fortune. The firm deploys capital across property and casualty insurance, specialty lines including marine and energy, and reinsurance treaties. It operates through Lloyd's syndicates and direct underwriting platforms. Geographic exposure spans North America, Europe, and emerging markets, with named regions including the United States and the United Kingdom. Confirmed portfolio exposures include catastrophe property and casualty, marine, and aviation risks. Team size and total deployment figures are not publicly disclosed. The firm maintains offices in Hamilton, New York, London, Pembroke, and Farmington. In 2023, the firm's parent SiriusPoint reported a combined ratio improvement, reflecting underwriting discipline and reduced volatility. Sirius International Managing Agency Limited operates under Bermuda's regulatory framework, benefiting from a class 3A or higher license. Its structural differentiator is the Lloyd's syndicate-based model combined with Bermuda direct underwriting, allowing flexibility across jurisdictions and risk types.
