Heat Waves in Europe Expose Insurance Gap

Europe is facing its fifth heat wave this year, and mounting economic losses are exposing a serious problem: traditional business interruption insurance often does not cover damage caused by extreme heat, according to reports by the Japan Times and Reuters published on August 16 and 17, 2026.

Heat waves reduce worker productivity, curb consumer spending, and increase operating costs. However, unlike damage from fires or floods, heat-related losses often stem from indirect business disruption rather than direct property damage, making them difficult to insure.

Hospitality Sector Hit Hard: Padua Loses Its Aperitivo Tradition

The hospitality sector is particularly affected. In the Italian city of Padua, cafés have welcomed guests for early evening drinks, known as aperitivo, for over a century, encouraging them to sit outside and socialize before dinner.

But as Europe suffers record-breaking heat, the traditional 6 to 7 p.m. slot has virtually disappeared as people seek air-conditioned indoor spaces, significantly reducing sales for many hospitality venues. The Japan Times reports that this shift is a direct consequence of the heat wave.

Growing Protection Gap for Businesses

Adding to the pressure on businesses is the fact that extreme heat is often not covered by standard business interruption insurance policies. This creates a growing protection gap for companies across Europe, leaving them exposed to financial losses without adequate coverage.

Reuters notes that heat waves are increasingly taking a toll on the European economy, and insurers find such losses difficult to cover precisely because they often arise from indirect operational disruption rather than property damage.
