Commercial insurance market report: Q3 2026

The U.S. commercial insurance market kept softening in the third quarter of 2026, but slowly and unevenly. Property buyers saw another round of double-digit rate cuts. Umbrella, excess and commercial auto kept rising. Workers' comp, cyber and management liability were close to flat. Carriers reported strong underwriting profits on a quiet hurricane season, which gives them room to compete for your account at year-end renewals.

This report covers July through September 2026, using rate indexes and the Q3 earnings releases that carriers published in mid and late October 2026. All figures are as of October 24, 2026.

Rates by line in Q3 2026

Marsh's U.S. Global Insurance Market Index for Q3 2026, published October 21, 2026, put the U.S. composite rate at -1%, after -2% in the second quarter. Globally, Marsh measured -5%, the ninth straight quarterly decline, per its global index page.

The Council of Insurance Agents & Brokers (CIAB) had not released its Q3 2026 property/casualty market survey as of October 24, 2026. The table uses its Q2 2026 survey, reported by Insurance Journal on August 20, 2026, as the latest broker survey available.

Marsh's numbers reflect the mostly larger accounts it places. CIAB surveys brokers across small, medium and large accounts, and its Q2 survey found small accounts down only 0.5% against 3.7% for large ones.

Line-by-line notes for buyers

Property. Marsh reported catastrophe-driven programs (typically more than $1 million in premium) down 13% and non-catastrophe programs (typically under $1 million) down 9%. Underwriters also loosened their submission requirements. Marsh said valuation and submission thresholds eased. That doesn't mean you can skip an updated statement of values: a good valuation is still what earns the best terms, and a coinsurance penalty after a loss costs far more than any rate cut saves.

Umbrella and excess. This is still the hard part of most programs. Marsh said direct-market capacity for umbrella and excess shrank in Q3 and new managing general agent capacity filled part of the gap, though MGAs offered smaller line sizes than traditional carriers. In practice, a $25 million tower now often needs more layers and more carriers than it did a few years ago. The driver is social inflation. See nuclear verdicts and social inflation: why liability costs keep rising and commercial umbrella insurance.

Commercial auto. Marsh said auto loss ratios have stayed above 100% for more than a decade. It also found buyers got better results when the same insurer wrote both auto and workers' comp, and many used higher retentions to absorb increases. An AM Best special report covered by Insurance Journal on October 22, 2026 found that commercial auto liability loss payments grew about 6.4% a year from 2014 to 2024, more than twice the 2.8% average economic inflation. That gap is why rates keep climbing. See why commercial auto insurance keeps getting more expensive.

Workers' compensation. This is the one casualty line where carriers are chasing business. Marsh said comp insurers sought new accounts and worked to keep existing ones. NCCI's 2026 State of the Line put the private-carrier combined ratio for 2025 at 91, so the line remains profitable. Comp is priced state by state through bureau loss costs, so check your own state's filing rather than the national trend. See workers' comp trends: frequency, severity and rates in 2026.

Cyber. Marsh said U.S. cyber rates were flat in Q3 after 13 straight quarters of declines. The National Association of Insurance Commissioners' cyber market report, covered by Business Insurance on October 21, 2026, found 2025 U.S. cyber direct written premiums of about $9.46 billion, up 3.5%. The industry loss ratio rose to 53% from 48.7%, and reported claims rose 20%. Rising losses and a flat rate usually come before tighter underwriting, so expect more questions on controls. See the cyber insurance market: capacity, pricing and appetite.

D&O and professional liability. Marsh measured U.S. D&O and professional liability each up 1%, and said D&O insurers generally cut back on capacity. After several years of price cuts in management liability, the decreases have stopped. See Directors and officers (D&O) insurance explained.

Carrier Q3 2026 results

Large commercial carriers reported Q3 underwriting results in the high 80s and low 90s. Catastrophe losses were moderate, and favorable reserve releases in most lines were partly offset by charges for older liability.

Three themes stand out for buyers.

Rate is still coming in, but less of it. Travelers reported Business Insurance renewal premium change of 4.1%, or 7.0% excluding property. W. R. Berkley reported average rate increases of about 4.0% excluding workers' comp. Both numbers are well below the increases of 2023 and 2024.

Carriers are walking away from cheap property. Chubb's North America Commercial net premiums written fell 2.7%. Chubb said that excluding large-account and E&S property and some other items, the business would have grown 1.7%. CEO Evan Greenberg said commercial P&C is getting more competitive "across the board," per Insurance Journal, and that some Chubb units were shrinking on purpose because pricing or terms were inadequate. Expect lead carriers to give up layers of large property programs instead of matching the lowest bid.

Old liability years are still costing money. Travelers' asbestos charge is a reminder that long-tail claims from decades-old policies keep developing. loss reserves and reserve development: why they matter to buyers explains how reserve charges feed into pricing. Several carriers that report later, including Cincinnati Financial (scheduled for October 26) and AIG (November 3), had not released Q3 results when this report was written.

Catastrophes: a quiet quarter, then Isaias

Gallagher Re's Natural Catastrophe and Climate Report for Q3 2026 put global insured natural catastrophe losses for January through September 2026 at $92 billion. That is 29% below the 10-year average of $128 billion and the lowest nine-month total since 2019. It also marked the sixth straight quarter without a single event over $10 billion in insured losses, per Business Insurance. U.S. severe convective storms (hail, tornadoes and straight-line wind) caused at least $43 billion of insured losses, the fourth straight year above $40 billion. This is why roof condition and wind/hail deductibles still draw scrutiny in the Plains and the South even when rates fall.

Hurricane Isaias came ashore as a Category 2 storm near Destin on the Florida Panhandle on October 9, outside the Q3 window. Karen Clark & Co. estimated privately insured wind and surge losses at about $3 billion, and AM Best called the storm an earnings event rather than a capital event, per Insurance Journal. Gallagher Re told Reinsurance News that it expects Isaias to have little effect on January 1 reinsurance pricing, citing record traditional and alternative capital. Panhandle and Gulf Coast accounts should still expect underwriters to ask for loss details and to hold named storm deductibles firm.

Deals and consolidation

• Zurich closed its purchase of Beazley. Zurich completed the £8.1 billion ($10.7 billion) acquisition on October 1, 2026 and is folding Beazley into its Global Specialty business, per Insurance Journal. Beazley is one of the largest cyber writers in the U.S. If you buy cyber or specialty coverage from Beazley, expect forms and service to stay as they are for now. Ask your broker at renewal whether anything changes. when your insurer is sold or merges: what happens to your policy covers what an ownership change does and does not do to a policy in force.
• Sompo agreed to buy a workers' comp specialist. A U.S. subsidiary of Sompo agreed on July 8, 2026 to acquire Service Insurance Companies for an undisclosed price, pending regulatory approval, per Reinsurance News.
• Agency M&A slowed sharply. OPTIS Partners counted 144 U.S. and Canadian agency and broker deals in Q3 2026, down 27% from 197 a year earlier, and 439 for the first nine months, down 19%, per Insurance Journal. Private-equity-backed buyers did 76% of the deals. BroadStreet Partners (57) and HUB International (22) were among the most active. If your agency sold, your agent and your policies normally stay put, but look at who now handles service and claims advocacy. See private equity and the consolidation of insurance brokers.

Regulation and courts

Georgia's 2025 tort-reform law got its first major appellate test. On September 9, 2026, the Georgia Court of Appeals held in Transcontinental Carriers v. Bennett that a plaintiff may describe injuries during the first, fault-only phase of a trial, per Insurance Journal. Defense lawyers had expected that phase to be limited to liability. It is one ruling, but it shows how court decisions can narrow a reform before insurers credit it in rates, which matters to Georgia trucking and contracting accounts. Tort law varies by state. See tort reform and liability insurance: what changes for business buyers.

What it means at your next renewal

For Q4 2026 and January 1, 2027 renewals, expect conditions close to Q3's. Property gets cheaper but by less than last year. Umbrella, excess and auto keep rising. Comp and cyber stay roughly flat for clean accounts. A practical plan:

1. Start 120 days out on property-heavy accounts. Carriers are competing for well-documented property. Send updated values, roof ages and COPE details (construction, occupancy, protection, exposure) early so your broker can market the program instead of just renewing it.
2. Ask for terms, not just rate. In a falling property market, better deductibles, sublimits and valuation terms are often easier to win than a deeper rate cut. Ask for wind/hail deductibles to go back to flat dollars, or ask for higher flood and earthquake sublimits.
3. Budget for casualty increases. For a hypothetical account paying $100,000 for property and $100,000 for umbrella, Marsh's Q3 averages imply roughly $10,000 less for property and $8,000 to $13,000 more for umbrella. The total barely moves. Your own loss history, class and limits will matter more than either average.
4. Restructure the tower before you cut limits. If umbrella pricing hurts, model a higher self-insured retention or a different layer structure (more carriers at smaller line sizes) before giving up limits that a contract or a lender may require. See umbrella vs excess liability.
5. Bundle auto and comp where it helps. Marsh's observation that auto renewed better when the same insurer wrote comp is worth testing with your broker, especially for fleets.
6. Clean up your cyber controls file. Flat rates plus rising claims usually mean more underwriting questions. Have your MFA, backup and endpoint-detection answers ready. See MFA, EDR and backups: the controls cyber insurers now require.
7. Ask about E&S-to-admitted moves, and how long they will last. Admitted carriers are quoting accounts that had moved to the excess and surplus lines market, and wholesale brokers at Burns & Wilcox told Insurance Business in October 2026 that the real question is whether those carriers stay at renewal. Before you switch, confirm the admitted form is at least as broad and ask how long the carrier has written your class.

Key takeaways

• Marsh measured U.S. commercial rates at -1% in Q3 2026: property -10%, casualty +6%, umbrella/excess +8% to +13%, cyber flat, and D&O and professional liability each +1%.
• CIAB's Q3 2026 survey was not out as of October 24, 2026. Its Q2 survey showed small accounts down only 0.5%, so smaller buyers should not expect large-account property cuts.
• Travelers, Chubb and W. R. Berkley reported Q3 combined ratios of roughly 84% to 91%, with renewal rate gains slowing to about 4% and continued charges on old liability.
• Nine-month global insured catastrophe losses of $92 billion were the lowest since 2019, and Gallagher Re expects Hurricane Isaias to have little effect on January 1 reinsurance pricing.
• For January 1, 2027, push for better property terms, budget for higher umbrella and auto premiums, and start early with complete underwriting information.
