Commercial Auto
As of Q4 2024, the narrative around claims remains focused on rising claims costs, particularly in the commercial auto insurance sector. While AM Best reported that U.S. P&C Insurers posted an underwriting loss of just $2.6B in 2024 compared to $24.6B in 2023, with a combined ratio down from 101.9 to 98.9 over the same time period, the Commercial Auto industry segment remained unprofitable with a combined ratio of 108.5.
Overall market trends specific to Commercial Auto are highlighted by the following key points:
Impact on Commercial Auto Insurance:
The frequency and severity of commercial auto claims increased in 2024, with 50% of CIAB’s P&C Market Survey (“Survey”) respondents reporting a rise in claims during Q4. This has led to a continued increase in commercial auto insurance premiums, which rose by 8.9% in Q4 2024, the highest among all insurance lines.
Rising Claims Costs
The cost of claims has been increasing, driven by factors such as higher repair costs due to safety technology and supply chain disruptions. Vehicles equipped with driver assistance systems, such as backup cameras, are more expensive to repair, sometimes costing twice as much as those without these features.
Electric Vehicle (EV) Risks:
The adoption of EVs in commercial and government fleets has introduced new risk factors, such as cyber threats from public charging stations and battery fire hazards, contributing to higher claims costs and insurance premiums.
Tightened Underwriting:
Due to increasing claims costs, underwriting has become more restrictive, with 41% of Survey respondents noting a reduction in underwriting capacity for commercial auto insurance.

estimated shortage of commercial drivers
Driver Shortages and Accident Rates:
The ongoing shortage of commercial drivers, estimated at 80,000 by the end of 2024, has led some companies to lower hiring standards, resulting in higher accident rates and subsequent claims.
Property Insurance
California Wildfires:
While not expected to impact insurers financials until 2025, the severe wildfires in Los Angeles County led to substantial claims. Munich RE estimated $1.2 billion in losses from the fires while Travelers Companies also anticipated a significant impact on their Q1 2025. Overall industry-wide insured losses are estimated between $28 billion and $40 billion.
Market Stabilization:
Despite Cat / Natural Disaster driven challenges, the property insurance market ultimately showed signs of stabilization in 2024. The large majority of clients experienced no more than single-digit rate increases, with some of the client base beginning to see no increase or even a reduction in premiums. This stabilization can be attributed to a multi-year efforts to address losses and restore profitability, alongside new capital entering the market.
Casualty Insurance:
Market Conditions:
Industry reports suggest casualty lines continue to see premium and rate increases due to uncertain liability loss trends. While competition for new business remained strong in many industries, substantial rate increases persisted for auto and umbrella liability, whereas workers' compensation rates remained flat.
Underwriting Profitability:
As discussed above, the U.S. P&C insurance industry reported improved underwriting results in 2024, seeing compression in both reported losses and combined ratio, indicating an increase in profitability. This improvement is largely driven by more profitability within personal auto insurance and significant rate increases to offset inflationary pressures on losses.

These developments underscore the dynamic nature of the insurance industry in Q4 2024, with various sectors adapting to rising claims, adjusting premiums, and implementing strategic measures to maintain financial stability. Insurers continue to implement more stringent underwriting practices and increase premiums to respond to unprofitability.
