The commercial property and casualty market entered a soft market in the first quarter of 2026, with average premiums declining across all account sizes for the first time in nearly nine years, according to The Council of Insurance Agents & Brokers’ Commercial P&C Market Index for Q1 2026.

The overall average premium change came in at -1.2%, ending a 33-quarter streak of increases and marking a sharp turn from Q4 2025’s 0.2% average increase.

The shift was broad-based. CIAB members responding to the survey cited lower pricing, more flexible underwriting terms, and expanded carrier appetite — including for risks that had previously been declined — as hallmarks of the changing environment.

Large accounts (generating more than $100,000 in annual commissions and fees) experienced the steepest declines, with premiums falling an average of 2.7%, the second consecutive quarter of decreases for that segment. Medium accounts ($25,000 to $100,00) followed at -1.9%, while small accounts (less than $25,000) were the only segment to post an increase, at 1.1%, though that figure was down from 2.8% in Q4 2025.

 

Commercial Property Leads the Decline

Commercial property posted the largest average premium decrease of any line of business in Q1 2026, falling 5.5% — a dramatic acceleration from the -0.7% recorded the prior quarter. The drop was fueled by aggressive carrier competition for both new and renewal business, the report said, with 72% of respondents observing an increase in property underwriting capacity, some describing it as “significant.”

“Property market was down significantly with all premium accounts,” one respondent from a large Southwestern brokerage firm noted in the survey.

The relief was most pronounced in non-catastrophe property, though respondents noted that “even some cat property saw rate decreases or improvements in terms/conditions.”

A March 2026 market outlook from AM Best, cited in the report, offered context for carrier confidence: the annual loss ratio for commercial property improved to 85% at year-end 2025, from 87.9% at year-end 2024, despite early 2025 California wildfires and notable severe convective storm activity and wildfires throughout the remainder of 2025.

AM Best attributed the improved results to disciplined underwriting, smart capacity deployment, and the strong premium base built during the hard market years, when commercial property increases exceeded 10% throughout 2023, peaking at 20.4% in Q1 2023.

Commercial Auto Remains the Outlier

While most lines followed the market’s softening trend, commercial auto continued to defy it. Premiums for the line rose an average of 5.8% in Q1 2026 — the highest increase of any line and the 59th consecutive quarter of increases. Even respondents who acknowledged some easing characterized the line as still “problematic.”

A separate AM Best report from March 2026 identified commercial auto as “one of the worst-performing P&C segments over the last 10 years.” According to AM Best data cited in the CIAB report, the line has posted annual loss ratios above 100% every year since 2014, with the lone exception of 2021. Net underwriting losses exceeded $5 billion in both 2023 and 2024, with loss ratios of 109.2 and 107.2, respectively.

Multiple factors have contributed to persistent claims pressure in commercial auto, the report said. Distracted driving and congested roads have kept claim frequency elevated, while social inflation and nuclear verdicts have amplified severity.

Rising medical costs after an accident and increased vehicle repair and replacement costs — driven by both inflation and the amount of technology used in new vehicles — have added further pressure. Notably, AM Best observed that the technology added to vehicles to make driving safer — such as telematics — appears to have also contributed to higher claims costs thus far.

Broader Line Movement

Nine lines of business recorded average premium decreases in Q1 2026, including cyber (-3.5%), workers compensation (-3.7%), D&O liability (-2.1%), and employment practices (-1.8%), the CIAB found. Among lines posting increases, general liability averaged 2.6% and umbrella averaged 4.8%. Surety bonds were flat at 0.0%.

Across all lines combined, the average premium change was -0.3%, and across the five major lines — commercial auto, commercial property, general liability, umbrella, and workers compensation — the average was 0.8%, down from 1.9% in Q4 2025.
