Catastrophe Loss Relief Drives Reinsurance Pricing Softening
RenaissanceRe's property book swung from a 148.7% combined ratio to 34.1% in a single year, and the relief is already showing up as give-back in reinsurance pricing.
RenaissanceRe Holdings Ltd (RNR), the Bermuda-based reinsurer, reported a Property segment combined ratio of 34.1% for the first quarter of 2026, down from 148.7% a year earlier, with the current accident year claims ratio falling to 27.2% from 145.1%. The segment's underwriting income turned to $593.863 million from an underwriting loss of $607.218 million in the prior-year quarter, and within that segment, net claims and claim expenses incurred tied to catastrophe activity swung to (5,443) in the current accident year from 1,431,394 a year earlier, while the catastrophe line's underwriting income rose to $447,956 from a loss of $666,993.
That relief is already feeding into pricing. Rli Corp (RLI), the specialty and E&S underwriter, said its Property segment premium fell 9% as the book mix shifted from catastrophe to non-catastrophe business, and reported renewal rate declines of 19% for hurricane risk and 16% for earthquake risk, even as it posted a combined ratio of 62 despite what it called increased catastrophe activity in parts of its book. SiriusPoint Ltd (SPNT), the specialty reinsurer, cut Property Cat Re premiums 31% inside a 10% decline in overall gross written premium, citing market conditions, while its loss ratio improved 15.5 percentage points and its combined ratio improved 12.9 points on lower catastrophe losses tied to the 2025 California wildfires.
Mgic Investment Corp (MTG), the mortgage insurer, moved in the opposite direction on reinsurance cost. Ceded losses incurred under its excess-of-loss and quota-share programs rose from $4.0 million in the second quarter of 2025 to $11.9 million in the first quarter of 2026 and $12.0 million in the second quarter of 2026, alongside a GAAP loss ratio that climbed to 14.1% in the first quarter of 2026 from negative 1.2% a year earlier. MGIC's risk factors continue to flag that pandemics, severe weather events, and climate-related developments may affect home prices and delinquency rates.
Cincinnati Financial Corp (CINF), the Ohio-based property-casualty insurer, had a catastrophe-loss contribution to its GAAP combined ratio that swung from as low as 1.0 percentage point to as high as 25.0 percentage points across recent quarters, with the overall combined ratio ranging between 85.2% and 113.3% over the same stretch. The company's combined ratio excluding catastrophe losses stayed comparatively narrow, between 82.7% and 88.3%, underscoring how much of the quarter-to-quarter swing in headline results traced to catastrophe timing rather than underlying attritional performance.
Florida-focused homeowners carriers held their catastrophe risk language steady through the window. American Integrity Insurance Group, Inc. (AII) repeated in both August 8-K filings that its loss reserves are estimates that may be inadequate, noting actual claims incurred have exceeded, and in the future may exceed, reserves established for claims, and reiterated that changing climate conditions may increase the severity and frequency of catastrophic events. Universal Insurance Holdings, Inc. (UVE), another Florida-concentrated insurer, carried the same catastrophe and severe-weather risk-factor language in its April and July 10-Q filings without revision.
Palomar Holdings, Inc. (PLMR), the specialty catastrophe insurer, had identical risk-factor text on the frequency and severity of weather events, the unpredictability of catastrophe occurrence, and the effect of rising replacement costs on claim severity in both its May and August 10-Qs, showing no hardening or easing of disclosure language even as reinsurance-side results moved sharply.
Guidewire Software, Inc. (GWRE), the P&C insurance software vendor, expanded its catastrophe risk factor between its June 10-Q and September 10-K filings to state that climate change and other environmental factors are contributing to an increase in erratic weather patterns globally and intensifying the impact of certain types of catastrophes, while also citing acts of terrorism, armed conflict, and geopolitical uncertainty including the war between Russia and Ukraine and conflicts in the Middle East as risks to its P&C insurer customers. Modiv Industrial, Inc. (MDV), a net-lease REIT, had geographic concentration in California that exposes it to earthquake and wildfire losses capable of producing a significant negative effect on its financial condition.
The reinsurance-side loss relief documented by RenaissanceRe and SiriusPoint, paired with RLI's rate declines on renewal hurricane and earthquake business, points to a pricing cycle that is giving back gains built after a heavier catastrophe stretch. RLI said it runs its actuarial loss estimate process twice a year, heading into the year and again at midyear, and was about to begin that mid-year review.
