For most commercial insurance lines, the hard market has already ended — rates began falling in mid-2024 and were still falling through the second quarter of 2026. But “over” doesn’t mean over for everyone. U.S. casualty is the one major line still trapped in hard-market conditions, and no honest analyst will put a date on when that segment turns.
What Does the Latest 2026 Data Actually Show?
The most complete picture comes from two quarterly sources: the broker Marsh’s Global Insurance Market Index and the Council of Insurance Agents & Brokers (CIAB) Commercial Property/Casualty Market Index. Their Q2 2026 readings, published in July 2026, tell the same story with different lenses.
Marsh reported that global commercial insurance rates fell 6% on average in Q2 2026, marking the eighth consecutive quarter of rate decreases — a decline that followed a 5% drop in Q1 2026. Every global region recorded composite rate decreases.
CIAB’s survey of U.S. brokers found commercial premiums fell 2.0% across all account sizes in Q2 2026, the second straight quarterly decline and the first back-to-back quarterly decreases since 2017. Its members reported premium decreases in 10 lines of business.
Line by line, the split is stark. Marsh’s Q2 2026 data showed property rates down 12% globally — the sharpest decline of any line — with U.S. property down 13% in its eighth consecutive quarter of decreases. Catastrophe-exposed U.S. programs above $1 million in premium saw rates fall 20%. Cyber rates fell 4% globally, their twelfth consecutive quarterly decline. Financial and professional lines fell 3% globally.
And then there is the outlier: casualty was the only major product line to record a global rate increase, up 2% on average (versus 3% in Q1 2026). Outside the United States, casualty pricing actually declined. Inside the U.S., it rose 7% — or 11% once workers’ compensation, the most competitive U.S. casualty line, is stripped out.
Why Did Property Turn First?
Hard markets end when capacity returns, and capacity returned to property first — largely through reinsurance. The January 1, 2026 reinsurance renewals told the story: broker Guy Carpenter reported its global property-catastrophe rate-on-line index fell 12%, with the U.S. and Asia Pacific down 12% and continental Europe down 15%. Rival broker Howden put the risk-adjusted decline at roughly 14.7%.
Behind those rate cuts sat two forces. First, a relatively benign loss environment: Guy Carpenter projected 2025 global insured losses at $121 billion, about 18% below the five-year inflation-adjusted average. Second, fresh capital: dedicated reinsurance capital was forecast to grow 9% in 2025, with another $50 billion of capacity expected to enter between 2025 and 2027. Strong insurer balance sheets, plus investment income from higher yields, gave primary carriers room to compete on price.
Marsh’s John Donnelly summed up the drivers in the Q2 2026 index release: positive insurer financial performance, a surplus of capital, lower reinsurance costs, and higher investment returns produced greater competition and contributed to lower rates. In property, all of those conditions were met.
Why Is U.S. Casualty Still Hard?
Casualty’s cycle is driven by courtrooms, not storm tracks — and the courtroom trends have not improved. Three pressures keep the line firm:
- Social inflation. Juries are awarding larger damages, and the trend in liability claim severity keeps running ahead of ordinary inflation. Marsh, CIAB, and broker Willis all cited ongoing litigation pressure as the defining casualty driver in 2026.
- Nuclear verdicts. Jury awards above $10 million continue to reshape loss development, particularly in commercial auto and umbrella/excess layers.
- Adverse reserve development. Carriers are still paying more than they originally reserved on old claims. AM Best found U.S. commercial auto recorded another $2 billion in reserve deficiencies in 2025, tied mostly to the 2023 and 2024 accident years — and the agency maintains negative outlooks on both commercial auto and general liability.
The capacity side confirms the strain. CIAB’s Q2 2026 survey found 40% of brokers reported a contraction in umbrella capacity, and umbrella premiums rose 5.3% — their 35th consecutive quarterly increase. Broader umbrella and excess markets keep pricing for verdict severity, not for the macro economy.
There are, however, early signs the pressure may be peaking. Willis noted in September 2026 that rate increases in the excess casualty market appeared to be approaching their peak, partly because new capacity was entering through broker-led facilities and newly formed managing general agents. Softening, if it comes, will arrive in casualty the same way it did in property: capacity first, rates second.
What Has to Happen Before the Whole Market Turns Soft?
The history of the underwriting cycle is consistent: a market doesn’t turn because rates feel high. It turns when three conditions are met at once — and in 2026, property met them while U.S. casualty has not.
- Capacity must return and stay. Property got this through reinsurance and alternative capital. Casualty capacity is still contracting in umbrella and excess layers.
- Combined ratios must sit under 100 for sustained periods. The industry got close: AM Best reported the U.S. P/C industry combined ratio improved to 92.5 in the first half of 2026 (net underwriting income nearly tripled to $31.2 billion), though it forecasts a full-year 2026 combined ratio of 96.9 as rate softening earns through.
- Loss trends must stabilize. Property benefited from a quieter catastrophe year. Casualty loss trends — bodily injury severity, medical costs, litigation — are still worsening, according to the American Property Casualty Insurance Association’s analysis of first-half 2026 results.
Until casualty’s underlying loss trends stabilize, carriers can’t price down with confidence no matter how much capital is available. That’s the honest answer to the timing question: watch verdict severity, reserve releases, and umbrella capacity — not calendar dates.
What Should Buyers Do in the Meantime?
A split market rewards buyers who treat lines differently. Property and cyber buyers have leverage: competition is real, so programs can be restructured — lower deductibles, broader terms, higher limits — while the softening lasts. Casualty buyers should plan as if the hard market continues: start renewals early, market the risk to more carriers, and document loss-control and safety programs so underwriters can defend the account internally.
