Heatwaves Drive Up Deaths and Pressure Insurance Costs, S&P Warns

S&P, a credit rating agency, warns that Europe's heatwaves could cut into life and health insurers' profits. The UK saw 2,877 extra deaths from two heatwaves in May and June 2026 — almost double the 1,504 from the entire summer of 2025. More claims may mean higher insurance bills, though ratings hold steady for now.
