Wheat futures in Chicago climbed to their highest level in over two years during early Asian trading, driven by concerns that disruptions to grain exports from the Black Sea region could prove more severe than previously anticipated. The ongoing conflict between Russia and Ukraine, the world's two largest wheat exporters, has already significantly hampered shipments from the area, and with export forecasts now being revised downward, the fallout is beginning to threaten future crop yields.

As Ukrainian strikes continue to disrupt shipping routes across the Black and Azov Seas, traders are grappling with increasingly difficult logistical hurdles. In response, Russia is contemplating a suspension of its floating export duties on wheat, barley, and corn through the end of 2026. Projections indicate that the country's total grain exports for August will slightly exceed 2 million tonnes—a figure that is 20% lower than the forecast provided by ProZerno just two weeks ago and less than half of the five-year average of 5.7 million tonnes for the month.

Tensions are also escalating in Ukraine, where the country's largest exporter, Kernel, reports that Russia's ongoing blockade of its Black Sea ports is not only restricting export capacity but also jeopardizing next year's planting season. The difficulty of moving crops out of the region is directly impacting farmers' ability to sow for the coming cycle.

On Wednesday, the most actively traded wheat contract in Chicago rose as much as 1.7%, reaching its highest point since May 2024, before paring some of those gains. Meanwhile, corn prices extended their rally for a sixth consecutive session—marking the longest winning streak in over a year—supported by a bleak U.S. crop outlook. Soybean prices remained largely unchanged during the session.
