Commercial insurance prices in the U.S. climbed 5.6% in the fourth quarter of 2024 compared to the same period in 2023, according to WTW’s latest Commercial Lines Insurance Pricing Survey (CLIPS).

This continued upward momentum in Q4 pricing reflects a nuanced market where certain segments like commercial auto liability hit record price increases, while others such as workers’ compensation, directors and officers liability, and cyber showed signs of moderation. The CLIPS data reveals a complex pricing landscape across different insurance lines and account sizes, with excess/umbrella liability maintaining significant double-digit increases even as commercial property price growth slowed considerably from 2023 levels, according to WTW.

Overall Commercial Insurance Pricing Trends

The commercial insurance market has experienced significant fluctuations in pricing over the past four years, the survey shows. Year over year price changes reached their peak at nearly 10% during the second through fourth quarters of 2020, marking a period of substantial premium increases for businesses across sectors. Following this spike, the market began to show signs of moderation, with quarterly price increases gradually declining to just below 5% by the fourth quarter of 2022.

More recently, the market has found a new equilibrium. Price increases rebounded slightly to above 6% in the second quarter of 2023, and have remained remarkably consistent over the past six quarters, hovering close to the 6% mark, according to the CLIPS report.

“The fourth-quarter data shows a continued upward trend in overall pricing, with signs of moderation compared to prior quarters,” said Yi Jing, senior director, Insurance Consulting and Technology at WTW.

CLIPS data indicates modest loss ratio improvements of 2.8% for 2024, even stronger than the 1.9% loss ratio improvement of 2023.

Notably, insurers report that claim cost inflation has remained lower than earned price increases for both 2023 and 2024, according to WTW.

Line-of-Business Performance Analysis

The commercial insurance market continued to see pricing pressure in Q4 for several key liability segments. Excess and umbrella liability coverage maintained its position as one of the market’s hardest segments, sustaining double-digit growth compared to the previous year.

Even more dramatic is the commercial auto liability segment, which has reached a historic milestone. Price increases in this line hit their highest level ever recorded in the history of CLIPS.

Commercial property presents a more nuanced picture in the current pricing environment. While the line continues to experience increases, the magnitude of price increases has diminished considerably compared to the aggressive pricing seen throughout 2023, WTW noted

What makes the commercial property segment particularly noteworthy is the scale of its quarter-over-quarter movement. Among all lines surveyed, commercial property demonstrated the largest shift from the previous reporting period, indicating a potentially significant inflection point in the property market cycle.

Not all segments of the commercial insurance market are experiencing upward pricing pressure. Several notable exceptions stand out from the broader hardening trend. Workers’ compensation continues to diverge from other casualty lines, maintaining its position as a relative bright spot for insurance buyers seeking rate relief.

Directors and officers liability coverage also bucks the trend, with specialty lines overall experiencing a small rate decrease primarily driven by ongoing price reductions in this segment. Similarly, cyber coverage—despite its volatile recent history—and surety bonds represent areas where pricing has stabilized or softened relative to other commercial lines.

Market Segmentation by Account Size

The commercial insurance market continues to show distinct pricing patterns when analyzed by account size, according to WTW

Small and mid-market accounts experienced a notable shift in the fourth quarter, with price increases moderating compared to the previous quarter. In contrast to their smaller counterparts, large accounts maintained consistent price increases from the previous quarter.
