The 2018 European heatwave cut EU wheat output by about 10 million tonnes, or roughly 10%, according to the FAO, with France losing over 20% of its grain harvest. Ukraine's wheat crop fell to 5 million tonnes, about 75% below normal.
A Met Office study links the heatwave to climate change and the article discusses longer-term climate risks for wheat growers.
Sharp European and Ukrainian wheat losses tighten global wheat supply and support export prices, particularly for feed-grade wheat that substitutes for corn. The longer-term climate risk argument adds to the case for a firm wheat price outlook.
