Industry Summary

The 2,578 property and casualty insurance carriers in the US underwrite insurance policies that protect policy holders against losses that may occur as a result of property damage or liability. Major types of policies include vehicle property and liability; property and liability; and general liability. Other types of policies sold include health, life, and accident insurance. Large firms may offer reinsurance policies, which limit the amount insurers can lose.

Uncertainty Related to Risk and Losses

Success in the property and casualty insurance business is dependent on a firm’s ability to underwrite and price risk accurately and estimate losses.

Natural Disasters and Other Catastrophes

Damage and destruction due to natural disasters and other catastrophes expose property and casualty insurers to the financial burden of covering massive losses.


Recent Developments

Jun 22, 2026 - Global Natural Disaster Insured Losses Reached $129 Billion Last Year
  • Global insured losses from natural catastrophes reached approximately $129 billion in 2025, according to Gallagher Re, marking the sixth consecutive year that insured catastrophe losses exceeded $100 billion worldwide. The US accounted for roughly $100 billion (78%) of the global total. The costliest event was the January Los Angeles wildfire outbreak, which generated an estimated $41 billion in insured losses. Severe thunderstorms remained the dominant loss driver, producing about $60 billion in insured losses globally, including roughly $51 billion in the US. Losses were heavily concentrated in the first half of 2025, while a notably quiet Atlantic hurricane season and relatively calm second half helped keep annual losses below the recent 10-year average. Catastrophic losses remained manageable for the insurance industry, despite continued pressure from growing exposure and climate-related risks.
  • The January 2025 LA wildfires are still having a big impact on the property and casualty insurance industry, according to the California Department of Insurance. Companies have already paid out more than $22.4 billion across tens of thousands of claims, showing just how massive the damage was. In response, California regulators are trying to stabilize the market by speeding up rate approvals and improving how insurers use catastrophe models, hoping to bring more carriers back into the state. State lawmakers are also stepping in with a proposed bill, the Disaster Recovery Reform Act, which would require insurers to have clear disaster recovery plans in place for handling claims during emergencies. It would also double penalties for insurers that violate fair claims practices during declared disasters. Overall, these efforts are aimed at making the system more reliable, protecting homeowners, and ensuring insurers are better prepared for future events.
  • In 2025, the US property and casualty insurance industry stayed largely profitable, continuing the momentum from 2024’s strongest underwriting results in over a decade. Homeowners insurance hovered near breakeven, with combined ratios around 99-100%, as disciplined pricing and careful underwriting helped offset losses from major catastrophes, especially California wildfires early in the year. Personal auto lines fared better, posting solid underwriting gains, while overall industry margins were supported by relatively calm catastrophe activity in the latter part of the year. Still, insurers like State Farm faced significant losses from wildfire claims, prompting rate hikes in hard-hit areas. These moves sparked customer frustration and drew regulatory attention, highlighting the ongoing tension between covering growing risks and keeping insurance affordable.
  • Soaring insurance costs in the US have intensified regulatory scrutiny as premiums for home and auto coverage climb at record rates. According to S&P Global, homeowners’ premiums rose 12.7% in 2023 and another 10.4% in 2024, with the average policy reaching about $1,900 in 2023, up nearly 50% from pre-pandemic levels. Over 5.3 million US households now pay more than $4,000 annually for property insurance. Auto insurance followed a similar trend, increasing 8.4% in 2023 and an additional 17.8% in 2024, according to the Bureau of Labor Statistics. Rising claims from natural disasters, high repair costs, and tighter reinsurance markets have pushed insurers to seek steep rate hikes. But as affordability worsens, regulators in states like California, Florida, and Louisiana are pushing back, rejecting or capping increases and signaling a shift toward more active oversight of the insurance industry’s pricing practices.
