KBRA Affirms Ratings for Hamilton Insurance Group, Ltd. and Hamilton Re Ltd.
30 Jun 2026 | New York
KBRA affirms the A insurance financial strength rating (IFSR) for Hamilton Re Ltd. (HRE) and the BBB+ issuer rating of Hamilton Insurance Group, Ltd. (NYSE: HG). The Outlook for both ratings is Stable.
Key Credit Considerations
The ratings reflect HRE’s strong capitalization, improving earnings profile, experienced management team and well-developed risk management framework. HRE remains a core operating company within HG and serves as the group’s principal Bermuda reinsurer and key capital-bearing entity. Recent results have benefited from profitable underwriting, favorable overall reserve development, strong investment performance and increasing diversification from related-party quota share arrangements across Hamilton’s broader underwriting platform. KBRA also views HG’s demonstrated access to capital, including use of third-party capital, reinsurance and collateralized structures, as supportive of financial flexibility and volatility management.
Balancing these strengths are HRE’s meaningful exposure to catastrophe, casualty reserve and investment risk relative to its scale. The company’s increased casualty weighting and proportional reinsurance activity provide diversification benefits but also heighten the importance of disciplined underwriting, reserve adequacy and group-level risk selection. In addition, HRE’s material investment in the Two Sigma Hamilton Fund (TSHF) remains a key credit constraint given its complexity, potential earnings volatility and limited utility as a near-term liquidity source. The ratings also consider HG’s reliance on dividends from HRE, although this is mitigated by HRE’s strong capital position, demonstrated dividend capacity and HG’s conservative financial leverage.
Rating Sensitivities
Positive rating action could occur if HRE demonstrates sustained profitable underwriting performance through the reinsurance cycle while maintaining strong risk-adjusted capitalization, favorable ERM practices and conservative financial leverage. Positive momentum would also require further evidence that the shift toward casualty, proportional and related-party quota share business is producing durable earnings diversification without materially increasing reserve volatility, casualty tail risk or operating leverage. A reduced earnings and capital reliance on TSHF, stronger ordinary liquidity excluding TSHF, and continued development of Hamilton’s market position and third-party capital capabilities could also support positive rating momentum.
Negative rating action could occur if HRE experiences a material deterioration in risk-adjusted capitalization, sustained underwriting losses, adverse reserve development, outsized catastrophe or aggregate losses, or meaningful volatility in TSHF that weakens capital, earnings or liquidity. Negative movement could also result from a weakening of ERM, governance or risk controls; a material increase in casualty, investment or operating leverage; reduced financial flexibility at HG or HRE; deterioration in liquidity or collateral resources; or a material increase in shareholder dividends or capital extraction that reduces HRE’s standalone financial strength.
