Summer heatwaves could shave 0.1 percentage points from 2026 French economic growth -ministry

PARIS, Sept 2 (Reuters) – This summer’s successive heatwaves could shave 0.1 percentage points off French economic growth on average this year, ​the Finance Ministry said on Wednesday.

The ‌ministry, however, stressed this was just a mere estimate at this stage and not an official update of its forecast for French growth, which currently stands at ‌0.7% ​for 2026.

• Last week, the ⁠INSEE statistics agency revised ⁠growth for the second quarter of 2026 from 0.2% in an initial reading down to 0.0%, after the euro zone’s second-biggest economy ​contracted by 0.2% in the first quarter.

• Finance Minister Roland Lescure said last week ⁠that the INSEE downgrade “is the ⁠first impact of the horrible summer ​that we had.”

• The INSEE downgrade puts the ​government’s full-year growth forecast of 0.7% all but ‌out of reach as the economy would need to grow 0.5% in both the third and fourth quarters to reach it, according to ⁠INSEE.

• Lescure told an economics conference last week that his ministry would need to factor in a ⁠likely weak ‌third quarter when it updated France’s ⁠growth and deficit forecasts in September ​before ‌presenting the 2027 budget bill in ​early October.

• ⁠One of the most severe heatwaves which occurred over the

summer in France was in the Bordeaux area, while a major

wildfire also hit the Fontainebleau forest near Paris in

July.
