US Commercial Premium Renewal Rate Increases Slowed in October: Ivans

Umbrella policies renewed at an average premium increase of 6.08% in October, but that figure was down from 6.40% a month earlier — a pattern of deceleration that ran through nearly every major U.S. commercial line, according to the Ivans Index. Only commercial property moved against the grain, accelerating to 5.37% from 5.11% in September. Workers' compensation stayed in negative territory at -1.45%, worsening from -1.14%.

Ivans, a Chicago-based insurance technology firm owned by Applied Systems, compiles the index from more than 120 million transactions across the U.S. market, spanning more than 38,000 agencies and 700 carriers and managing general agents. That breadth makes the index a widely watched proxy for commercial pricing. It measures renewal rate change, not new business, so it reflects what existing policyholders actually paid — a caveat worth keeping in mind when extrapolating to the wider market.

Which lines accelerated, and which cooled?

October's line-by-line results show a market easing off the pricing throttle:

• Commercial auto: 2.80%, down from 3.29% at the end of September.
• Business owners policy (BOP): 5.21%, down from 5.45%.
• General liability: 3.10%, down slightly from 3.19%.
• Commercial property: 5.37%, up from 5.11% — the lone acceleration.
• Umbrella: 6.08%, down from 6.40%.
• Workers' compensation: -1.45%, down from -1.14%, meaning renewals cut premiums by more than the prior month.

Six lines, five decelerations. The exception matters: commercial property's pickup suggests loss-cost pressures in catastrophe-exposed lines have not fully receded, even as casualty-heavy lines like umbrella and auto cool.

What happened in the third quarter?

The quarterly picture is starker. In the third quarter of 2026, every major line of business posted a lower average premium renewal rate change than in the prior quarter — except workers' compensation, which saw a slight increase, though Ivans did not specify the figure.

Commercial auto averaged 3.63% in Q3, down sharply from 4.93% in Q2. The trend is not new: commercial auto renewal increases have been declining since April 2026, Ivans said. For perspective, the same line averaged 7.6% in Q3 2025 — meaning the pace of increase has more than halved in a year.

Commercial property followed the same trajectory. Its average renewal rate change fell to 5.65% in Q3 2026 from 6.40% in Q2, after reaching 7.64% in Q3 2025. That is a decline of roughly two full percentage points year over year, even before October's modest rebound.

The takeaway in plain words: commercial insurers are still raising premiums at renewal, but at roughly two-thirds to half the pace of a year ago, depending on the line.

What is not said?

The index reports averages, not dispersion. A 5.37% average for commercial property could conceal wide variation between coastal and inland risks, and Ivans does not break out geography, account size, or loss history. The release also does not explain the drivers — whether deceleration reflects competitive pressure, softer loss trends, or underwriting appetite — leaving buyers to draw their own conclusions. And workers' compensation's deepening negative rate is described without comment on whether it signals deteriorating underwriting discipline or simply continued favorable claims experience in the line.

For risk managers and buyers, the direction is unambiguous: pricing leverage is drifting back toward the customer across most lines. Whether property's October uptick is noise or the start of a reversal will show up in the November index — and that is the number worth watching next.
