Record heat has gripped Europe again this summer. Cafes in the Italian city of Padua stand empty during what used to be the bustling aperitivo hour. Temperatures push past 40 degrees Celsius in places. Businesses lose customers who flee indoors for air conditioning. And the insurance industry finds itself staring at losses it cannot easily cover.
The pattern repeats across the continent. Fifth heatwave of the year. Trains delayed. Factories running hotter cooling systems. Agricultural output down. Worker productivity sags. Yet traditional policies rarely pay out for these hits. The gap between economic damage and insured recovery has grown stark. Reuters reported last summer’s European heatwaves caused €43 billion in lost economic output. Insured payouts reached only about €500 million.
Federica Luni leads the hospitality association APPE Padova. She described the shift in her city. “The traditional 6-7 p.m. slot has all but disappeared.” More than 80 percent of roughly 600 surveyed businesses reported turnover drops of around 20 percent. “A 20% decline wipes out your margin.” The real loss, she added, lies in revenue that never materializes. Outdoor seating sits unused. Customers stay home.
Swenja Surminski manages climate and sustainability at Marsh. She put the core problem plainly. “Heat in itself is not a traditionally insured risk.” Extreme heat seldom destroys buildings the way floods or storms do. The financial pain comes from operational disruption. That distinction matters. A 2023 survey of 9,000 small and medium-sized European firms found just 28 percent carried business interruption coverage tied to property insurance. Only 17 percent held non-damage business interruption protection for events such as strikes. Heat rarely qualifies.
Companies have begun to flag the pressure in earnings reports. Swedish shop-fitting provider ITAB Group. Italian cement maker Buzzi. French payments company Worldline. Each cited heat impacts or warned of future risks. The effects compound. Heat pairs with drought, raises wildfire odds, strains power grids. Modeling these interactions proves far harder than pricing a single storm.
Europe warms faster than any other continent. Average temperatures in Western Europe ran nearly 10 degrees Celsius above the 1961-1990 baseline on one day in mid-August, according to Reuters Climate Monitor data. Thirty-five percent of companies tracked by CDP now list heatwaves as a material risk. Manufacturing, services, infrastructure and food sectors lead the list.
Insurers recognize the shift. They predict higher premiums. Larger losses. No one views this as temporary. Bloomberg spoke with brokers and carriers who described a new era of catastrophe risk driven by rising temperatures. Munich Re has pointed to the dangerous mix of El Niño patterns and long-term warming. Losses from natural disasters are expected to double every eight to nine years.
Swiss Re examined the fallout in detail. Extreme heat threatens property, specialty and life-and-health lines. Power outages trigger business interruption claims. Wildfires damage assets. In life and health, heat stress drives higher morbidity and mortality, especially among outdoor workers and vulnerable populations. Medical claims rise. Workers’ compensation costs climb. Liability exposure grows when employers or schools fail to protect people from excessive temperatures. The World Economic Forum projects annual corporate losses from extreme heat could reach $404 billion to $448 billion by 2035. Swiss Re.
Moody’s has quantified the insurance shortfall too. Last summer’s heat delivered €43 billion in short-term economic damage across the EU but produced only €500 million in covered claims. That works out to roughly 1 percent insured. Similar ratios appear in other analyses. Moody’s warned of rising implications for casualty insurance absent stronger workplace temperature rules. Europe lacks uniform legislation on the matter.
Health consequences add another layer. The World Health Organization reports heat as the leading climate-related cause of death in the region. Heat-related mortality rose 30 percent over the past two decades. More than 60,000 lives were lost to heat in 35 countries in 2022. The toll stood at 47,500 in 2023. Projections point to 120,000 annual heat deaths by 2050 without further adaptation. WHO.
Wildfires tell part of the story as well. Spain faced its worst season in years. France battled blazes. Economic costs mount while insured portions remain limited. One analysis placed Spain’s 2025 wildfire losses near €5 billion, with only €1 billion covered.
Parametric insurance has emerged as one response. These policies pay out automatically when temperatures cross agreed thresholds. No lengthy claims process. No need to prove exact financial damage. Agriculture already uses them to cover yield losses from heat. Experts see potential expansion into transport, workforce protection and public sector applications. The European parametric market could reach $7.93 billion by 2031, growing at 9.5 percent annually, according to KBV Research.
Aidan Kerr heads UK and Ireland public sector solutions at Swiss Re. “Parametric insurance can really play a role,” he said. Yet Surminski at Marsh cautions that adaptation must come first. Companies should invest in cooling systems, redesign workplaces and test supply chains against prolonged heat. “Take action to avoid the losses rather than address them once they’ve occurred.”
Recent reports reinforce the urgency. A WWF study highlighted how climate and nature risks threaten financial resilience and insurability across Europe. Extreme summer events in 2025 alone generated an estimated €43 billion in damages. WWF. Habtoor Research assessed the broader economic toll of the 2026 heatwaves, noting that total climatological losses in Europe had reached roughly €46 billion in 2022 and warning of continued pressure on the insurance sector.

The message from executives and analysts converges. Adaptation and new product designs must advance alongside traditional coverage. Otherwise the protection gap will widen further. Businesses in hospitality, manufacturing, agriculture and infrastructure already feel the strain. Insurers face pressure to price risks accurately while avoiding withdrawal from entire markets. Europe stands on the front line of a warming world. Its insurance system is being tested in real time. The numbers do not lie. The heat is here. The coverage, too often, is not.
