The commercial property/casualty insurance market closed out 2024 with premium increases averaging 5.4% in the fourth quarter, up only slightly from the 5.1% increase in Q3, according to The Council of Insurance Agents & Brokers’ (CIAB) Commercial Property/Casualty Market Index Q4/2024.

Small accounts those with less than $25,000 in commissions and fees) experienced the smallest increase with an average 3.6% increase in premiums, according to the CIAB’s survey of member firms. This lower rate of increase aligns with the commercial insurance market’s strong appetite for small business risks, the CIAB noted.

As one survey respondent from a large Northwestern brokerage firm noted, “appetite for small business remains strong,” indicating a continued focus on this segment of the market.

Changes in Premiums

While the overall market showed consistency in pricing, individual lines of business painted a more varied picture. Commercial property, a line that has been challenging for insurers, showed signs of stabilization, according to the CIAB. Premium increases for this line averaged 6.0% in Q4, a notable decrease from the 7.9% seen in Q3 and a significant drop from the 11.8% recorded in Q4 2023, CIAB noted.

Commercial auto, on the other hand, bucked the trend of moderation. After seeing shrinking premium increases in the first three quarters of 2024, Q4 witnessed a reversal for this line. Commercial auto premiums experienced an average increase of 8.9% in Q4, up from an 8.5% increase in the previous quarter.

Umbrella liability coverage also experienced renewed premium growth. After reaching a peak average increase of 22.9% in Q3 2020, premiums for this line had moderated to a 7.0% increase in Q1 2024. However, Q4 saw a resurgence, with premiums climbing back up to an 8.7% increase, according to the index.

Market Stability Indicators

Despite these fluctuations in specific lines, the overall market showed signs of stability, the CIAB survey found. Many respondents reported “no material change” in market conditions, with underwriting practices remaining consistent.

However, challenges persist, particularly in property coverage. Insurers continue to push for higher deductibles, especially for properties exposed to fire, wind, and hail risks. Additionally, there’s an increased need to create layered coverage programs to fully insure risks, indicating ongoing complexity in this sector of the market.

Cyber Insurance

The cyber insurance market has witnessed a notable shift, with premiums declining for a third consecutive quarter. The fourth quarter of 2024 saw a record low decrease of 1.8% in cyber insurance premiums. This trend signals a significant turnaround in a sector that had previously experienced sharp increases due to escalating cyber threats, the report noted.

Several key factors are contributing to this positive shift in the cyber insurance landscape, according to the CIAB.

Increased carrier capacity has played a crucial role, with 64% of respondents reporting greater underwriting capacity for cyber insurance products. This expansion in capacity has been accompanied by growing competition in the market, CIAB stated.

In 2023, the number of carriers underwriting cyber insurance in the U.S. increased to 218, up from 214 the previous year. This increased competition has exerted downward pressure on pricing, benefiting businesses seeking cyber coverage.
