War and heat: Why are wheat prices soaring?

What the report says

Wheat prices have climbed sharply as two pressures converge: renewed disruption to Black Sea grain exports and weather-related damage to harvests in major producing regions. In Al Jazeera’s report published Aug. 31, 2026, Russia and Ukraine had recently intensified attacks on each other’s grain terminals, vessels and port facilities in the Black Sea area, complicating shipping during the peak export season.

The article says those disruptions have pushed Chicago wheat futures to a three-year high, while also raising transport costs and slowing cargo loadings. Al Jazeera noted that both countries remain major players in the global wheat market, so interruptions to their exports affect availability and, more immediately, affordability. The story also cited concern in Russia’s Rostov region, where officials declared a state of emergency after port closures and navigation problems in the Sea of Azov and Black Sea basin led to grain piling up at farms.

Beyond the war, the report linked higher prices to drought and heat in other producing countries. It pointed to reduced wheat output in the United States, Canada and parts of Europe, and said South Africa’s Swartland region could see a smaller harvest because of rising temperatures and low rainfall. Al Jazeera reported that climate patterns such as El Niño may further strain supplies.

The piece also provided broader context: a 2022 Black Sea Grain Initiative once helped stabilize exports from Ukraine, but Russia ended the deal in 2023. Analysts quoted by Al Jazeera said a more stable shipping route or increased exports from other producers could ease pressure, though no quick fix is apparent.
