The hot summer is burning through Europe's economic estimates
Summary
- The summer's extreme weather in Europe, including heatwaves and droughts, has already cost hundreds of billions of euros, with full economic impacts expected to materialize in the coming years.
- Western Europe's July temperatures were 4.8 degrees above normal, delaying harvests and reducing corn yields by 6–7%, according to Reuters.
- Transport disruptions, such as the Rhine River's low water levels, are projected by ING to reduce Germany's GDP by 0.3 percentage points this year.
- Climate change could significantly impact European economies, with Allianz estimating a potential 5–7% reduction in cumulative growth for vulnerable countries by 2030, while inflationary pressures may lead to more aggressive ECB interest rate hikes.

The cost of weather phenomena in Europe this summer has already been estimated at hundreds of billions of euros. Record heatwaves, droughts, and forest fires have hit the same areas simultaneously, and their impact is also visible in economic statistics. The full costs will only materialize years from now.
The average temperature in Western Europe in July was 4.8 degrees higher than the long-term normal. As a result, the harvest has been delayed, and for example, the corn yield by July is 6–7 percent smaller than normal, according to figures collected by Reuters.

The numbers are also concretized in transport. The water level of the Rhine River in Germany has decreased to 23 centimeters, which is clearly below the 78-centimeter lower limit of transport restrictions. As shipping traffic has decreased, it also affects the economy: ING estimates that the halt of Rhine traffic alone will cut Germany's GDP by 0.3 percentage points this year.

In Hungary, cooling problems have decreased nuclear power plant production, which, according to the local MBH Bank, reduces GDP by 0.1 percentage points for each week of shutdown. Allianz, on the other hand, estimates that a mere two-week heatwave in June eroded 0.3 percentage points from the entire European GDP, and by 2030, climate change could take 5–7 percent of cumulative growth from the most exposed economies such as Spain, France, and Italy. The euro area's growth is estimated to remain around one percent this year, so the impact on the economy would be significant.
The effects are visible not only in production but also in prices. For example, according to an ECB research paper, the 2022 heatwave increased food inflation in the euro area by 0.67 pp, with a greater impact in the south. Inflation in Europe could rise by 0.3-1.2 pp by 2035 due to climate change, depending on the climate scenario. Even now, heat is a risk, as is El Niño, both of which cause inflationary pressures. Tax revenues are estimated to decrease by 1.8 percent in France and 1.3 percent in Italy and Spain due to lost production, so the weather also impacts public finances.
European economic growth has already been under pressure, but the summer heat threatens to burn through even current estimates. Accelerating inflation, in turn, could force the ECB to raise interest rates more aggressively than anticipated.
