S&P: Europe's Heatwaves Pressure Insurer Earnings as UK Excess Deaths Surge

S&P warns that Europe's heatwaves could hit life and health insurers' earnings as heat-related deaths climb. The UK recorded 2,877 excess deaths from two heatwaves in May and June 2026 — nearly double the 1,504 across all of summer 2025. Rising claims may push premiums higher, though S&P's insurer ratings stay unchanged for now.
