According to Experts.news, the U.S. Department of Agriculture has sharply raised its forecast for Ukraine’s ending stocks of wheat and feed grain for the 2026/27 season—to a total of nearly 12 million metric tons.
In the USDA’s July forecast, ending stocks for these two groups were estimated at approximately 6.26 million metric tons, while in the August WASDE report, the figure rose to 11.93 million metric tons. Thus, in just one month, the estimate increased by 5.67 million metric tons, or approximately 91%.
The most significant revision was made to the corn outlook.
The USDA raised its forecast for corn ending stocks from 2.06 million to 4.86 million metric tons—more than a 2.3-fold increase. This represents an increase of 2.8 million metric tons.
The reason is almost entirely due to changes in two indicators: the corn harvest forecast was increased by 1.8 million metric tons—to 31.8 million metric tons—while exports were simultaneously reduced by 1 million metric tons—to 22 million metric tons. The USDA left domestic corn consumption unchanged at 7.2 million metric tons.
As for wheat, ending stocks were increased even more in percentage terms—from 2.53 million to 4.8 million metric tons, or by approximately 90%.
For the entire feed grain group, the stock forecast was raised from 3.73 million to 7.13 million metric tons.
The USDA attributes the deterioration in export prospects to logistical disruptions resulting from the escalation of the conflict in the Azov and Black Seas.
An even more dire scenario was previously presented by the Kyiv office of the USDA’s Foreign Agricultural Service (FAS). It expects that, if maritime logistics problems persist, Ukraine’s carryover stocks of all grain crops could approach 25 million metric tons.
According to FAS/Kyiv, the total storage capacity for grains and oilseeds in Ukraine exceeds 74 million metric tons, but certified grain warehouses provide approximately 23 million metric tons of capacity. Ukrainian authorities have also acknowledged the need for an additional 10–12 million metric tons of temporary storage capacity in the event of prolonged disruption to exports via the Black Sea.
This issue has direct economic implications for farmers. Given a large harvest and limited exports, domestic supply is increasing, which could put pressure on domestic purchase prices while simultaneously driving up costs for storage and alternative logistics.
As of August 13, the situation with the ports remains challenging: Russian attacks continue to target Ukrainian port infrastructure, particularly along the Danube corridor.
Thus, the main risk for the Ukrainian grain market in the 2026/27 season is no longer just the size of the harvest. If restrictions on maritime exports remain in place, Ukraine may face the need to store millions of metric tons of additional grain domestically.
