Global wheat production in 2026 could decline by 3.8% compared to 2025—to 810.7 million metric tons, according to a forecast by the FAO (Food and Agriculture Organization of the United Nations).
Based on August data, the FAO raised its forecast for the global wheat harvest by 0.5%, but despite this revision, production may still be 3.8% lower than last year’s figure (798.5 million metric tons), according to the report.
The increase in the August forecast is primarily due to upward revisions in estimates for Canada, Morocco, Russia, and Ukraine. These increases more than offset the downward revisions for the EU and the United Kingdom, where a lack of rainfall and high temperatures led to lower yields.
The FAO’s August forecast for the world’s total grain harvest has been lowered by 3.4 million metric tons—to 2.98 billion metric tons—compared to the July level. “Taking into account the latest adjustments, production in 2026 could be 2% lower than last year’s level, which would mark the most significant annual decline since 2018,” the report states.
The revision of the overall forecast is largely due to a 0.6% downward revision of the corn harvest estimate to 1.309 billion metric tons. This is primarily due to worsening harvest forecasts in the EU, where hot and dry weather conditions in key production regions—particularly in France and Poland—have led to a deterioration in crop conditions and reduced expected yields to below the five-year average, according to FAO experts.
In addition, based on the latest official estimates, production forecasts for India and Paraguay have been revised downward. This decline more than offset the upward revisions for Argentina and Brazil, where the 2026 harvest could turn out to be significantly higher than average levels.
