French Heatwave to Shave 0.1 Points Off 2026 GDP, Hit Agriculture and Logistics

France's 53 days of summer heatwaves are projected to reduce 2026 GDP growth by 0.1 points, with the shock concentrated in agriculture (maize yields down) and spreading to vegetables, electricity demand, public works, and European logistics chains. The estimate is preliminary and based on sectoral analysis; the full macroeconomic impact remains uncertain as knock-on effects propagate.
