According to Beinsure Data, Bermuda reinsurers expected improved underwriting performance in 2025 will be driven by accelerating premium rates with a market reset in pricing, terms and conditions, even amid heightened catastrophe losses, inflation and economic uncertainties.
Global ratings agency Fitch recently reported strong to very strong Insurer Financial Strength (IFS) ratings for Bermuda and U.S. insurers and reinsurers.
Arch received an ‘AA-’, RenaissanceRe an ‘A+’, and both SiriusPoint and Hamilton an ‘A–’, all with Stable Outlooks.
TOP 10 Reinsurers in Bermuda by Premiums
The bar chart displaying the top 10 reinsurers by Net Premiums Written. Each bar is colored differently to represent each reinsurer, with the assets measured in billions of dollars.
High ratings are due to companies’ solid capital positions, rated ‘Strong’ to ‘Extremely Strong’ as of year-end 2025 by Fitch Ratings’ Prism Global capital model. These re/insurers also maintain low to moderate financial leverage ratios, from 7% to 26%.
Arch, Hamilton, RenaissanceRe, and SiriusPoint improved their combined ratios due to fewer catastrophe losses and favorable underwriting conditions. SiriusPoint is expected to continue enhancing its operating results, boosting its positive financial performance and earnings outlook.
Arch’s ‘AA–’ rating is driven by favourable combined ratios and a high return on average equity (ROAE). Throughout its 24-year history, Arch has consistently reported underwriting and net income profits. The company also benefits from very low combined ratios in its mortgage segment, which recently saw substantial reserve releases due to favourable mortgage delinquency cure activity.
Fitch considers Arch’s company profile as ‘Favourable’, and Hamilton, RenaissanceRe and SiriusPoint as ‘Moderate’.
The change in Bermuda Reinsurers’ premiums

Bermuda reinsurers’ underwriting profitability is likely peaking at current levels, as price increases moderate and loss-cost inflation persists
However, returns will continue to be favorable as market conditions remain attractive, with the negative effect of natural disasters on catastrophe claims reflected in pricing in 2025, Fitch Ratings says.
For Bermuda-based (re)insurers followed by Fitch, the meaningful underwriting improvement seen in 2024 will be limited in 2025 as premium rate increases decelerate.
The hardening market continued at the January 2025 reinsurance renewal, with flat to up in most lines as the supply/demand imbalance narrowed, supported by relatively limited new capacity entering the market and deteriorating loss-cost trends from social inflation.
Analytics expect market conditions to remain favorable at the 2025 renewals, although with stabilizing rates as pricing is generally sufficient. (Re)insurers are also expected to mostly maintain the tighter terms and conditions negotiated in 2023.
The underlying combined ratio is expected to stabilize or improve slightly in 2025, as rate increases wane and loss-costs continue to increase. The combined ratio will approximate 85–86% for 2023, a meaningful improvement from 92.7% in 2022. Catastrophe losses will represent 3–4 percentage points on the 2023 combined ratio, down sizably from 9.8 points in 2022.
Shareholders’ equity grew 23% at 2024 from 2023, with ROAE comfortably above the cost of capital, and expected to approach 20% in 2024. Returns were driven by increased underwriting and investment income, equity market gains and stabilization of unrealized bond losses. Capital levels were supported by common equity issuances to support growth, and reduced return of capital.
Bermuda’s implementation of a 15% corporate tax will marginally reduce its economic advantage but the island’s established position in the global (re)insurance marketplace will likely endure.
Additionally, the recent life insurer-focused solvency review also will help the domicile maintain its Solvency II (S2) equivalence with the EU.
