Extreme Heat and Drought Trigger Significant Economic Losses Across Europe

Extreme weather events this summer are causing substantial economic damage across Europe, with some estimates suggesting that heat and drought could reduce the European Union's overall economic growth to near zero. According to the Triodos Bank, extreme heat and drought could reduce EU economic growth by 1 percent this year. Allianz estimates that a two week heat wave in June alone may have reduced Europe's GDP by 0.3 percentage points. The most severe impacts are expected in Southern Europe, where France could see a GDP reduction of 1.4 percent, potentially leading to an annual economic contraction of 0.6 percent.

The economic disruption is manifesting across several sectors. Low water levels on the Rhine and Danube rivers have severely limited cargo traffic. In Germany, ING estimates that the low water levels on the Rhine could lower GDP by 0.3 percentage points. Energy production has also been affected, as several nuclear power plants have curtailed or shut down production due to cooling difficulties. In Hungary, MBH Bank calculates that the situation at the Paks nuclear power plant reduces the expected GDP growth by 0.1 percentage points per week. The Hungarian government is attempting to prevent a total shutdown by building a sill and using submersible barges.

Agriculture has suffered significant losses, with late harvested crops like maize and sunflower seeing yield drops of 6 to 7 percent in July. In Hungary, agricultural output fell by 16 percent in 2022 compared to the previous year, which reduced GDP by 1 to 2 percent over two quarters. Beyond immediate losses, economists warn of long term consequences. University of Mannheim economist Sehrish Usman notes that the economic impact often grows in the years following an extreme event due to a chain of slow economic consequences. Additionally, the hospitality industry in Southern Europe may face a shift in tourism patterns as vacationers move north to avoid extreme heat.
