Europe’s recent heatwaves are driving mounting business losses while exposing limits in how well existing insurance covers extreme weather impacts, according to multiple reports.

One analysis points to a “protection gap,” noting that extreme heat is often not covered under standard business interruption policies. This means companies can face significant financial damage and lost income without receiving commensurate compensation.

The reports also cite broader economic estimates. Moody’s is described as estimating that last summer’s European heatwaves caused about €43 billion in lost economic output, while insurers generated roughly €500 million in insured payouts. The difference is used to illustrate how limited claims are relative to the scale of losses. Overall, the coverage focuses on the gap between the economic cost of heat and the level of insurance payouts, with attention on how coverage terms and policy design affect businesses’ ability to recover.
