California’s Insurance Reform: Will Catastrophe Modeling Save the Market?
Published Date: 03/15/2024
California’s insurance market has been under significant stress for years. Rising wildfire risks, floods, inflation, and a strict regulatory framework have led insurers to scale back or exit the state entirely. But recent action from the California Department of Insurance (CDI) may mark a turning point. Insurance Commissioner Ricardo Lara’s proposed rule to allow insurers to use forward-looking catastrophe modeling is a bold step in a broader reform initiative aimed at stabilizing the market.
This change could reshape how insurers set rates, potentially creating a more accurate and competitive insurance environment in the state. But the proposal also raises questions about the balance between fairness and transparency. Here’s a breakdown of what the reform means, why it matters, and how it could impact homeowners.
1. The Problem: A Market Built on Outdated Rules
For more than 30 years, California has relied on Proposition 103, a 1988 voter initiative that regulates how insurers set rates. While designed to protect consumers from excessive premium hikes, Prop 103 requires insurers to base their rate changes on historical loss data, preventing them from considering future risks or predictive models.
As California’s environment becomes more unpredictable—with longer wildfire seasons, stronger storms, and rising flood risks—insurers argue that the historical model no longer reflects the current risk landscape.
“The problem is that companies are only allowed to use historical data,” an ABC10 report explained. “This doesn’t allow them to set prices on a more accurate, granular level.”
This disconnect between outdated pricing models and current realities has led many insurers to leave California altogether or dramatically reduce their exposure in high-risk areas.
2. The Proposed Fix: Forward-Looking Catastrophe Modeling
Under the new proposal, insurers would be allowed to use predictive catastrophe models when submitting rate filings. These models, which incorporate AI, meteorological data, satellite imagery, and climate projections, can simulate how future disasters might affect specific locations. This would allow insurers to set more precise rates based on forward-looking risks rather than relying solely on historical data.
For example, two homes in the same ZIP code could have vastly different wildfire risks depending on their location, vegetation, and mitigation efforts like defensible space. Homeowners who invest in fire-safe construction and mitigation could see lower premiums, while homes in high-risk zones could face higher rates.
This nuanced pricing, already common in states like Florida and Colorado, would allow insurers to better reflect property-level risks rather than using broad regional averages.
3. Why It Matters: A Path to Market Recovery
The proposed rule has significant implications for California’s insurance market. By allowing insurers to use predictive models, the state could restore market stability, encourage insurers to re-enter high-risk areas, and foster competition—ultimately leading to lower premiums.
As ABC10 explained:
“Rates are high. Competition is non-existent for the most part. So as these regulations start going into place and as carriers start entering the market and start competing with one another, we know what happens when all the carriers come back—then premiums will start coming down.”
This reform is a cornerstone of Lara’s Sustainable Insurance Strategy, a broader initiative to modernize California’s insurance framework and rebuild stability in the state’s market.
4. A Shift Decades in the Making
For years, insurers have struggled to operate profitably under Prop 103’s restrictions, especially in the face of escalating wildfire risks. The result has been market disruptions of historic proportions:
- State Farm stopped writing new homeowners policies in 2023.
- Allstate, Farmers, and Nationwide followed suit, scaling back or halting new business.
- The FAIR Plan, meant as a “last resort,” ballooned to cover more than 350,000 homes, tripling its enrollment from 2018.
Allowing predictive catastrophe modeling could be the key to reversing this trend. By accurately pricing risk, insurers would have more confidence to re-enter high-risk markets, particularly in wildfire-prone areas.
5. What Is Catastrophe Modeling — and Why Wasn’t It Allowed Before?
Catastrophe (cat) modeling is a technique that combines historical data, climate forecasts, and real-time environmental data to predict how future disasters might unfold. These models take into account:
- Fire ignition probabilities and spread patterns
- Vegetation and topography
- Wind direction and humidity
- Building materials and home-hardening features
In other states, insurers routinely use third-party firms like AIR Worldwide and RMS to model potential losses from events that haven’t yet occurred. But in California, Prop 103 prohibited the use of these forward-looking models, which limited insurers’ ability to price risk based on current and future conditions.
The new rule marks a breakthrough in how California addresses climate-driven risks, acknowledging that traditional, historical models no longer work in today’s volatile environment.
6. Consumer Concerns: Transparency and Oversight
While the reform has received support from the insurance industry, consumer groups have raised concerns about transparency. Critics worry that proprietary catastrophe models—often developed by private firms—lack transparency and accountability, making it difficult for the public or regulators to fully understand how rates are set.
As one consumer group noted, “We worry the newly proposed regulation is not transparent enough.”
To address these concerns, the CDI’s proposal includes strict disclosure requirements, ensuring that insurers explain how their models work and how they determine rates. All rate filings will still require final approval from the California Department of Insurance, giving regulators the power to ensure fairness and oversight.
7. What Homeowners Can Expect
If the new rule is implemented, homeowners can expect gradual changes to the insurance market:
- Short term (2024): Premiums may continue to rise as insurers adjust to inflation and existing losses.
- Medium term (2025–2026): More insurers are likely to return to the market, increasing competition.
- Long term: Rates may stabilize and potentially decrease as competition resumes and risk is priced more accurately.
Homeowners who invest in home-hardening measures could see premiums drop as insurers use property-specific data to offer discounts based on risk mitigation.
In the meantime, experts recommend that homeowners:
- Keep their current policies active to avoid lapses.
- Document any home improvements made to reduce risk, such as fire-resistant roofing or defensible space.
- Consult with their brokers to explore updated coverage options and discounts.
8. The Bigger Picture: Balancing Risk and Fairness
The introduction of catastrophe modeling represents a fundamental shift in how California approaches property insurance. It’s a necessary step to align risk pricing with reality in the face of climate change, but it also comes with challenges.
The key will be balancing innovation with fairness—ensuring that the new system doesn’t lead to unfair rate increases or leave vulnerable homeowners without options. As regulators work to implement these changes, they must ensure that the benefits of predictive modeling are shared equitably across the state.
9. The Bottom Line
California’s new catastrophe modeling proposal is a critical turning point for the state’s struggling insurance market. If successful, it could:
- Encourage insurers to return to the market.
- Create fairer, property-specific pricing.
- Reward homeowners who mitigate risks.
- Restore competition, which is key to lowering premiums.
With these reforms in place, California could finally move towards a more stable and sustainable insurance market, providing homeowners with better protection and more affordable coverage.
As ABC10 summarized: “Competition is non-existent for the most part. So as these regulations start going into place and as the carriers start entering the market and start competing with one another, we know what happens when all the carriers come back—premiums will start coming down.”
This optimism is a welcome sign after years of market turmoil. If this proposal delivers on its promises, California homeowners could finally see relief from the rising costs and limited options that have plagued the insurance market for so long.
