Global commercial insurance rates fell 6% in the second quarter of 2026, the eighth straight quarterly decline, and every major line joined the retreat except one: casualty, up 2% globally and 7% in the US, the sole line Marsh's Global Insurance Market Index still classifies as hardening (Marsh, July 2026).

Read line by line rather than composite by composite, the print is four separate rate-adequacy trajectories running at once, and only one of them is being priced to keep pace with its own severity trend.

Key Takeaways

  • Global commercial rates fell 6%, the eighth straight quarterly decline, while casualty rose 2% globally and 7% in the US, the only line still classified as hardening.
  • US directors and officers rates turned positive at 1% after a 3% decline in the first quarter, the first positive US D&O print since the line began softening.
  • 118 federal securities class action filings in the first half, annualizing to roughly 236 against 205 for all of 2025 and the highest since 2020, with 18 AI-related suits already ahead of the 17 filed in all of 2025.
  • Cyber's twelfth consecutive decline ran against a 53.0 industry loss ratio, the highest since the ransomware surge, with surplus lines carriers at 55.9 against 50.2 for admitted.
  • Excess casualty is priced up in the mid-teens against a blended US casualty print of 7%, so the headline averages a layer keeping pace with severity and layers that are not.

Four Lines, Four Trajectories in One Quarter

The Global Insurance Market Index nets renewal-level, year-over-year rate changes across regions and lines into one composite. That composite fell 6% after a 5% decline in the first quarter, the steepest print of an eight-quarter run. Underneath it the four major lines split into two pairs moving in opposite directions and at markedly different speeds.

LineGlobal Q2 2026US Q2 2026Prior quarter (US)
Property-12%-13%-9% (Q1)
Casualty+2%+7% (+11% ex-comp)+9% (Q1)
Financial & professional lines-3%+1% (D&O)-3% D&O (Q1)
Cyber-4%-2%-2% (Q1)

Property is steepest and still accelerating, from 9% down in the first quarter to 12% down in the second (Insurance Journal, July 2026). Cyber's 4% global decline extended a run stretching back three years, to a market still hardening in mid-2023. Casualty decelerated from a 3% global increase to 2%, but keeps the only positive sign, with the US book, up 7% overall and 11% excluding workers compensation, doing nearly all the lifting.

Financial and professional lines fell 3% globally while the US segment moved the other way. D&O rates there rose 1% after a 3% first-quarter decline. John Donnelly, Marsh's president of global placement, framed the pattern as underwriters "seeking to differentiate themselves" through broadened coverage and improved terms as capacity chases the softening lines.

A single 6% composite cannot carry that spread. It nets a 12-point property decline, a 4-point cyber decline and a 2-point casualty increase into one number, and by the time D&O's US turn folds in, the composite has stopped describing any actual line of business.

What Each Line's Rate Is Actually Tracking

D&O's four-point swing is small in isolation and specific in its trigger. Federal securities class action filings ran to 118 in the first half of 2026, annualizing to roughly 236, some 15% above the 205 recorded in 2025 and the highest since 2020 (The D&O Diary, July 2026).

Settlement values moved with them. The median first-half settlement ran $18 million to $20 million, above the full-year 2025 median of $17.6 million and well above the 2017-2025 median of $13 million, with four mega-settlements of $100 million or more carrying roughly a tenth of the half's value. AI has become its own filing category: 18 AI-related suits in six months, already ahead of the 17 filed in all of 2025.

Against that docket a 1% increase reads as underwriters catching up to severity rather than getting ahead of it. The accident years written through 2023, 2024 and most of 2025 were priced down while filing volume and settlement values were already climbing. A single positive quarter does not reprice business already on the books, so reserve reviews on those D&O vintages carry a severity trend the written rate history from those years does not show.

Cyber has no equivalent trigger yet. The industry loss ratio reached 53.0 in 2025, its highest since the ransomware surge, with surplus lines carriers at 55.9 against 50.2 for admitted (Risk & Insurance, July 2026, citing AM Best). Direct premium reached $7.5 billion, up from $7.1 billion, though largely on one carrier's book transfer rather than organic growth.

A 53 loss ratio is not alarming on its own. Cyber's distribution-heavy, MGA-fronted structure typically carries an expense ratio in the mid-to-high 30s, putting an all-in combined ratio in the high 80s to low 90s. What twelve consecutive quarters of decline changes is trajectory. Each further quarter of falling premium against a claims environment AM Best already describes as lengthening in tail lifts the loss ratio through the denominator alone, before frequency or severity move at all.

Casualty's blended figure is an average, not a level. On Marsh's own earnings call, CEO John Doyle described excess casualty pricing as "still up in the mid-teens, which is really a reflection of the very challenging litigation environment" in the US. If excess layers, the part of the tower most exposed to nuclear verdicts and litigation funding, price mid-teens while primary and blended layers move single digits, the blended 7% is an average of a layer keeping pace with severity and layers that are not, not a market-wide adequacy signal.

The Regional Spread Inside a Single Global Number

The composite compresses a wide regional range as well as a wide line range. India, the Middle East and Africa led with a 16% decline, then the Pacific at 13%, Latin America and the Caribbean at 9%, the UK at 8%, Canada at 7%, Europe at 6% and Asia at 5%. The US, down 2%, was the shallowest market in the index.

Every region declined, so the spread is degree rather than direction. A 14-point range between steepest and shallowest is still wide enough to change how a multi-territory program or a global quota share should be read.

A cedant or reinsurer pricing a global casualty or financial-lines quota share off the blended composite is assuming the book's territorial mix resembles the index's, which it rarely does. A treaty weighted toward IMEA or Pacific property is riding a market softening twice as fast as the US. A book concentrated in US casualty and financial lines sits in the two segments where rate is still catching up to loss cost rather than running ahead of it.

That dispersion is why a single global rate-on-line adjustment applied across a multi-territory treaty misstates adequacy in both directions at once: understating margin erosion where the local market softens fastest, and overstating it where price is still being pushed up by claims experience the composite does not carry.

None of the four line-level gaps, or the eight regional ones, closes or widens on the composite's schedule. Property's own repricing trigger, per Marsh's placement leadership, is contingent on a storm season this cycle has not yet delivered, and cyber's is a loss ratio on a chart rather than a filing count an underwriter has to answer at the next renewal.
