Employer Health Insurance Costs Projected to Spike in 2027
Employers predict an average 8.2% increase in the cost of their health insurance plans for next year, with some estimates reaching 11%, representing the sharpest jump in more than two decades. Workers will likely shoulder a portion of these rising costs through higher deductibles or premiums. This development highlights the growing financial pressure on households as employer-sponsored coverage becomes less affordable.
Japan’s Major Insurers Announce Auto Premium Hikes for 2027
Sompo Holdings (Sompo Japan) announced that it will raise average auto insurance premiums by approximately 5% starting in January 2027. This follows a previous 1.8% increase in July 2026 and comes amid soaring repair costs and increased insurance payouts per accident. Other major Japanese insurers, including Tokio Marine, have also implemented or planned similar hikes (e.g., 6.5% effective October 2026) to address rising parts prices and accident repair expenses.
California FAIR Plan Rate Increases and Market Shifts
The California FAIR Plan, the state’s insurer of last resort, is proceeding with a rate increase of approximately 29% to 35.8% for homeowners policies, pending regulatory approval. This move reflects the strain on last-resort insurers as traditional carriers retreat from high-risk wildfire zones. Concurrently, Allstate Insurance plans to begin writing new home insurance policies in California for the first time since 2022, marking a potential shift in market availability, albeit with specific conditions attached.
Surplus Lines Insurance Booms as Traditional Insurers Retreat
As traditional insurers withdraw from areas vulnerable to extreme weather, demand for "surplus lines" insurance—often used as a last-resort coverage option—is booming. This trend indicates a growing gap in accessible coverage for households in high-risk climate zones, forcing consumers into more expensive and less regulated policy structures.
Local view
Western New York: Local media reports indicate that while some small businesses and individuals in Western New York will see health insurance premium increases of up to 12–13.5% for 2027, others may see flat rates. The variance suggests regional differences in insurer strategies and risk assessments compared to national averages.
United Kingdom: In Scotland, commentators warn that with bad weather costs hitting £1.2 billion, disputes over insurance payouts and coverage definitions are expected to rise significantly. This reflects broader concerns about the adequacy of current insurance frameworks in handling increasing climate-related claims.
Context & numbers
- US Car Insurance: The average annual cost of full-coverage car insurance rose 1% in the first half of 2026 to $2,237. Insurify projects increases in 32 states by year-end.
- ACA Marketplace: For 2026, the median proposed premium increase across ACA Marketplace insurers was 18%. For 2027, filings suggest continued upward pressure, with some examples showing monthly premiums rising from $316 to $546 over two years for specific demographic profiles.
- Global Climate Losses: Climate disasters could cost $450 billion in a typical year, but insurers are covering a shrinking share of these damages, leaving more financial burden on individuals and governments.
On the radar
- October 2026: Tokio Marine’s 6.5% auto insurance premium increase takes effect in Japan.
- November 2026: Mandatory liability insurance (Jibaiseki) premiums in Japan are scheduled to increase by approximately 1,000 yen for two-year contracts.
- Ongoing: Watch for final regulatory approvals on the California FAIR Plan’s ~29–35% rate hike requests, which will directly impact hundreds of thousands of homeowners in high-risk zones.
