Insurers Warn Newsom Wildfire Plan Would Raise Premiums
On August 27, executives from major insurance companies sent a letter to California Governor Gavin Newsom warning that his proposal to shift utility wildfire liability to property insurers would result in significant premium increases for policyholders. The insurers argue that limiting their ability to recoup losses from utilities that start wildfires would place the financial burden directly on their balance sheets, forcing them to raise rates to maintain solvency. This development highlights the ongoing tension between climate liability reform and consumer affordability in the state’s property insurance market.
Surplus Line Insurance Booms as Traditional Carriers Retreat
A Washington Post report published on August 31 reveals that "surplus line" insurance—often referred to as last-resort coverage—is experiencing a boom as traditional insurers withdraw from areas vulnerable to extreme weather. As major carriers exit high-risk wildfire and flood zones, more Americans are forced into these non-standard markets, which typically offer less consumer protection and higher costs. This trend underscores the growing gap in affordable coverage for households in climate-exposed regions.
ACA Marketplace Premiums Projected to Rise 15% in 2027
Recent data indicates that for 2027, the median proposed premium increase across 276 insurers participating in ACA Marketplaces is 15%. This follows a sharp rise in 2026, where average out-of-pocket premiums for enrollees increased by $65 per month compared to the previous year. The continued upward trajectory in health insurance costs is driven by medical inflation and the expiration of enhanced subsidies, significantly impacting household budgets.
Local view
California: Local media and stakeholders are closely watching the legislative battle over wildfire liability. The Los Angeles Times reports that insurers are actively lobbying against Governor Newsom’s plan, arguing it will destabilize the market. Meanwhile, Claims Journal notes that lawmakers have introduced an alternative bill that would update wildfire response protocols without banning insurers from suing utilities, suggesting a potential compromise is being sought to prevent further premium spikes.
