A memo from the nonprofit Inside Track alleges that some insurance companies may be manipulating climate-risk projections to protect profits. This practice could potentially impact homeowners across the United States by driving up insurance premiums and limiting coverage availability.
Why it matters
Insurers may manage down long-term risk estimates to maintain short-term profitability, a trend that shifts the burden of physical risk onto household budgets. This can lead to non-renewals and higher costs for homeowners already facing a tightening insurance market.
Homeowners premiums rose between 18% and 43% across four U.S. regions from 2018 to 2024, while 2024 non-renewals were 61% higher than the previous year. Estimates suggest nearly 40 million U.S. homes face a risk of losing private coverage.
The players
Inside Track
A nonprofit organization that monitors institutional risk and published the recent memo on insurance industry modeling.
Munich Re
A global reinsurance company that provides coverage to primary insurers and helps determine industry-wide pricing standards.
Swiss Re
A major reinsurance provider that underwrites risk for primary insurers, influencing how companies assess catastrophic potential.
The details
Insurance companies reportedly adjust forward-looking risk models to avoid revealing high physical-risk projections that could threaten their market position. When insurers anticipate worsening environmental risks, they often respond by raising premiums, narrowing coverage terms, or exiting specific geographic areas entirely. This creates a cycle where reduced coverage is statistically linked to negative local outcomes, including higher foreclosure rates and declining property values.
Timeline
2018 to 2024: Average U.S. homeowners premiums increased by 18% to 43%.
2022: Munich Re and Swiss Re held 25% of global reinsurance premiums.
2024: Insurers issued over 2 million non-renewals.
September 2024 to December 2025: California FAIR Plan enrollment grew by 43%.
December 2024: California approved new wildfire catastrophe modeling rules.
Money Landscape
The insurance sector is currently transitioning from historical data to forward-looking climate risk models, a shift that complicates traditional premium pricing. This move follows the approval of new wildfire catastrophe modeling rules in California in December 2024.
Homeowners in high-risk areas may face rising premiums or the sudden loss of coverage if insurers exit their market. Consult a licensed insurance professional to discuss coverage alternatives if your policy is not renewed or if premium hikes threaten your monthly budget.
The takeaway
Insurance providers may prioritize short-term profit over long-term risk transparency, affecting your ability to secure affordable coverage. Homeowners should track their policy renewal dates carefully and prepare to shop for alternative coverage if they receive a non-renewal notice.
