The escalating climate crisis is posing an existential threat to the disaster insurance industry as we know it. Soaring risks from wildfires, floods, and storms are rendering coverage increasingly unaffordable and unavailable in high-risk areas, with grave implications for homeowners, businesses, and the broader financial system. As the recent catastrophic wildfires in Los Angeles starkly demonstrate, the insurance sector faces immense challenges in adapting to the new reality of a rapidly warming world.
The Rising Cost of Climate Disasters
The numbers are staggering. The Los Angeles wildfires alone could cost insurers up to $30 billion, according to estimates from Wells Fargo and Goldman Sachs. That’s on top of the billions in losses from other climate-fueled disasters in recent years. In California, premiums have already skyrocketed by 43% between 2018 and 2023. Many insurance companies are pulling out of the state altogether as claims costs far outpace premium revenue.
The grim trajectory is clear: As the risks continue to mount, insurance will become increasingly out of reach for those who need it most. Homeowners in wildfire-prone areas may find themselves unable to insure their properties at any price. Businesses may be forced to shoulder uninsurable risks or shutter operations entirely. The knock-on effects could ripple through the economy, depressing property values and destabilizing financial markets.
Broken Risk Models
At the heart of the insurance industry’s predicament is a risk modeling framework ill-equipped for the climate change era. Insurers have long relied on historical loss data to price policies and manage their exposure. But in a world where “100-year storms” hit every few years and unprecedented mega-fires engulf major cities, the old actuarial playbooks are increasingly obsolete.
“The future of disaster insurance is under threat all over,” warns Eugenia Cacciatori, co-author of Disaster Insurance Reimagined and a senior lecturer in management at Bayes Business School in London. “Insurance is caught between two poles: the need to charge prices proportionate to growing risks, and the need to keep coverage broadly affordable.”

Translating long-term climate projections into reliable pricing and underwriting models for specific perils remains an immensely complex challenge. Insurers are racing to develop new predictive tools powered by advanced data analytics and climate science. But for now, many are flying blind into an uncertain future.
The Affordability Crisis
As insurers raise premiums to reflect surging risks, coverage is fast becoming unaffordable for many. That leaves millions of homes and businesses dangerously exposed to catastrophic loss. In 2023, only 14% of Californians had wildfire coverage beyond convoluted “difference in conditions” policies that pay out very little.
If insurance becomes out of reach, property values could plummet in high-risk areas like wildfire zones and coastal flood plains. A 2019 report warned that homes in wildfire-prone areas of California could lose 70% of their value by 2030 if insurance collapses. That would be a devastating blow to household wealth and local economies.
Toward Climate Resilience
Adapting insurance systems for an era of runaway climate risk will require a collaborative effort between insurers, governments, and residents. Insurers need to develop more sophisticated risk models and find ways to incentivize policyholders to invest in resilience measures like fire-resistant retrofits. Governments must strengthen building codes, improve land-use planning, and provide funding for large-scale mitigation projects.
- Public-private partnerships could help expand coverage while managing risk exposure for insurers.
- Risk transfer programs could unburden private insurers by shifting the highest-risk policies to well-funded public entities.
- Resilience requirements like brush clearing and fire-hardening could be prerequisites for coverage in wildfire zones.
“Insurers shouldn’t be investing directly in resilience or mitigation measures,” Cacciatori cautions. “Ultimately the responsibility for those decisions to be taken in the public interest has to lie with governments.”

The path forward is arduous and the political obstacles are immense. Special interests are mobilizing to block reforms that threaten corporate profits or land-use restrictions. Many homeowners object to paying for resilience retrofits or being forced to relocate from high-risk areas. Insurers fear overregulation could further destabilize shaky markets.
An Uncertain Future
Yet the clock is ticking for insurance markets on the frontlines of the climate crisis. Rising risks are already eroding availability and affordability of coverage in California, Florida, Louisiana and beyond. As capital flees massive wildfire and hurricane losses, once-insurable regions face being abandoned to fend for themselves.
If insurers pull out, banks could stop issuing mortgages, businesses may flee, and economies could crumble. The risks aren’t just physical – they’re existential. How to reinvent disaster insurance for the age of superstorms and mega-fires is one of the great challenges facing world leaders this decade.
The survival of insurance markets – and the cities and homeowners who depend on them – hangs in the balance. As evidence mounts that the climate crisis is here and now, insurers are in a race against time to adapt before the next megadisaster strikes.
