News Summary

California Governor Gavin Newsom is reviewing Senate Bill 429, aiming to create the first public wildfire catastrophe model in the U.S. The bill seeks to reform how wildfire risks are assessed and how insurance is regulated. Insurers with significant premiums will be required to submit fire risk data, increasing transparency. The initiative is backed by the American Property Casualty Insurance Association but also faces scrutiny from consumer advocates who are wary of the regulations’ transparency. The legislation is part of a broader effort to address wildfire risks amid rising costs and climate volatility.

California Governor Gavin Newsom is currently reviewing Senate Bill 429, a legislative proposal that aims to establish the nation’s first public wildfire catastrophe model. This initiative seeks to reform the state’s approach to wildfire risk assessment and regulation of insurance, an issue that has gained increasing attention in light of frequent wildfires in the region.

The proposed bill intends to enhance California’s existing wildfire risk evaluation and mandates insurers with over $10 million in written California premiums to submit fire risk data for their insured residential properties. This data will be made publicly accessible by the California insurance commissioner, allowing for greater transparency concerning fire risk.

Senate Bill 429 also proposes the creation of a Wildfire Safety and Risk Mitigation Program under the California Department of Insurance. This program would allocate funding for research needed to develop the public wildfire catastrophe model. This model will help formulate risk mitigation strategies, inform actuarial analyses, and enhance oversight of insurance rates, addressing ongoing concerns about affordability in an increasingly volatile climate.

This proposal aligns with California’s ongoing efforts to refine its wildfire risk modeling framework; earlier in July, the California Department of Insurance certified the Verisk Wildfire Model as the first approved model for setting insurance rates. The Verisk model is currently utilized in other states and was developed by the company’s Extreme Event Solutions unit.

The American Property Casualty Insurance Association (APCIA) has expressed support for the legislation, emphasizing that advanced catastrophe models are crucial for stabilizing the California insurance market and improving access to coverage. However, consumer advocacy groups, such as Consumer Watchdog, have raised concerns regarding the transparency and accountability of the new regulations, specifically about the algorithms used by insurers in developing climate models.

State Senator Dave Cortese highlighted the significance of the public model in providing lawmakers with important data necessary to answer constituent questions about insurance rates, particularly regarding rising costs and regional disparities. Additionally, Insurance Commissioner Ricardo Lara has voiced support for the public wildfire model, emphasizing that it will enhance insurance affordability and yield essential insights to combat wildfire risks more effectively.

SB 429 is a component of a broader legislative package designed to tackle wildfire risks and insurance challenges, having faced minimal opposition during the legislative process. If enacted, the implementation of the public model is expected to improve transparency in wildfire risk assessment and may serve as a check on the models used by private insurers along with the Department of Insurance’s feedback.

Consumer advocates have been critical of current strategies for lacking transparency and have called for adjustments to ensure that mitigation efforts are reflected in insurance pricing. They cite models used in Colorado as successful examples of effective insurance pricing strategies. It is important to note that the passage of SB 429 does not guarantee the model’s establishment or ensure that its findings will differ from those produced by the private models used by insurers.
