Europe's 2025 Wildfire Season: A $424 Billion Wake-Up Call for Insurance

The 2025 European wildfire season was not just an ecological crisis—it was a stress test for a global insurance system already buckling under climate change. France bore the brunt, with authorities evacuating over 220,000 people and economic losses estimated between €10 billion and €15 billion [$11.5–$17.3 billion] . Yet the deeper story is not the scale of the fires, but the yawning chasm between the damage and what is actually covered by insurance. Across the EU, only about a quarter of climate-related catastrophe losses are insured, and in some countries that figure drops below 5% . The 2025 season has exposed a fundamental mismatch: losses are rising rapidly, but insurance penetration remains low, and the private market is retreating rather than expanding coverage.

France at the Epicentre: A Humanitarian and Economic Toll

France was the crisis's epicenter. By late July 2026, the Gironde and Biscarrosse wildfires had burned more than 45,000 hectares in the coastal southwest, and more than 115,000 hectares had burned nationally—nearly double the 2022 total . Around 240 homes were destroyed, and the entire Cap Ferret peninsula was evacuated by land and by sea in what authorities described as the country's largest peacetime evacuation . Combined with over 75,000 evacuations in Spain, the total across affected regions exceeded 295,000 people .

Morningstar DBRS estimated total economic losses for France at €10 billion to €15 billion, but cautioned that insured losses would be "significantly less" . The reason is twofold. First, much of the damage has been to rural, forested, or unbuilt land that is not insured or is excluded from standard property policies . Second, and more critically, French law treats wildfire as an ordinary fire insurance claim under a standard home policy's garantie incendie—not as a "catastrophe naturelle" (CatNat) .

The CatNat Exclusion: Why France Has No State Safety Net for Wildfire

France's CatNat regime, established by the 1982 Act, is a public-private partnership that covers non-insurable risks such as floods, earthquakes, and drought-related clay soil shrinkage . It is financed via a compulsory surcharge on all property insurance premiums—raised from 12% to 20% on January 1, 2025—and backed by the state-owned reinsurer Caisse Centrale de Réassurance (CCR) . When an event is declared a CatNat by the government, policyholders are guaranteed compensation, and insurers can draw on state-backed reinsurance.

But wildfires, along with storms, hail, and snowfall, are explicitly excluded from the CatNat regime . French law considers these risks "insurable" under standard private fire cover, so they fall entirely outside the state-backed scheme . French Finance Minister Roland Lescure confirmed that insurers would cover the cost of evacuations and property damage from private policies, with no state backstop . This means all wildfire risk in France is shouldered by the private insurance market alone—with no public reinsurance pool, unlike the flood component of CatNat .

The EU's Insurance Protection Gap: A Structural Vulnerability

The French situation is a microcosm of a continent-wide problem. According to the European Central Bank, only about 25% of climate-related catastrophe losses in the EU are insured, and in several countries this share is below 5% . Insurance Europe, the European insurance industry association, pegs the EU's NatCat protection gap at around 65%, meaning two-thirds of disaster costs are uninsured . The ECB expects this gap to widen further, as climate-driven losses outpace insurance uptake .

For context, Spain's 2025 wildfire season resulted in close to €5 billion in total economic losses but only €1 billion insured—a 20% coverage rate . Across Europe, wildfire has still not generated a single billion-dollar insured loss event, not because the fires are small, but because so little of the damage is actually covered by insurance . Munich Re reported that Spain's 2025 burn area was nearly 400,000 hectares, close to five times its 20-year average, yet insured losses remained contained .

The implications for homeowners are stark. As Swiss Re's Head of Catastrophe Perils Balz Grollimund noted, wildfire losses are generally not covered by national insurance pools in southern Europe, meaning homeowners must seek private insurance themselves—and as climate risk intensifies, demand is likely to rise even as supply tightens .

A Global Retreat from Fire Risk Coverage

The retreat from fire risk is not limited to Europe. In 2025, the global natural catastrophe protection gap hit a record $424 billion, as private insurers pulled back from climate risk rather than absorbing rising costs . Major U.S. carriers—State Farm, Allstate, and Chubb—have withdrawn from writing new homeowner policies in California . Similar retrenchment pressures are emerging in Florida and Louisiana, where escalating hurricane losses are destabilizing private insurance markets, as well as in parts of Australia and southern Europe . Since 2022, seven of California's top twelve insurers have paused or restricted new business, pushing more homeowners onto the state's FAIR Plan, the insurer of last resort .

Reinsurers have reinforced these dynamics. Through 2025-2026, they have maintained disciplined capital deployment and underwriting standards, tightening primary insurers' ability to absorb wildfire risk . Global natural catastrophe insured losses totaled USD 107 billion in 2025, driven heavily by secondary perils like wildfires, which accounted for a record 92% of total global insured losses . The Los Angeles wildfires alone generated around USD 40 billion in insured losses .

Implications: A System at the Edge of Insurability

The 2025 European wildfire season has exposed a structural mismatch that cuts across geographies. Economic losses are rising rapidly, but insurance penetration remains low (≈25% in the EU), and France lacks any public compensation mechanism for wildfire. The result is a large and growing protection gap that falls on uninsured homeowners, domestic insurers, and—ultimately—taxpayers, but with no state backstop in France's case . Globally, insurers and reinsurers are pulling back from fire risk rather than expanding coverage, suggesting the gap will worsen without policy intervention .

Analysts and regulators have begun exploring solutions. The European Central Bank has called for policy options to reduce the climate insurance protection gap . Morningstar DBRS backed a proposed EU-wide public-private reinsurance scheme to improve coverage and financial stability, noting that only 20% of natural catastrophe losses in the EU are currently insured . But these proposals face deep political and economic hurdles: in France, the existing CatNat scheme is already under strain from rising claims for drought-related clay soil movement, and adding wildfire risk would place additional pressure on a system designed for "uninsurable" perils .

For now, Europe's wildfire risk remains in the hands of private insurers, at a moment when the global industry is actively repricing and retreating from climate exposure. The 2025 season may not have produced a single billion-dollar insured loss in Europe, but it has made one thing clear: the current architecture is not built for the fires of the future.
