US Grain Futures Hit Multi-Week Lows Amid Trade and Geopolitical Shifts

Agricultural futures for wheat, soybeans, and corn dropped to multi-week lows on August 5, 2026, as speculators engaged in profit-taking and long liquidation. December corn fell to $4.64, November soybeans dropped to $11.87 1/2 before further declining toward $11.5 per bushel, and soft red winter wheat fell to $6.39 1/4.

Speculators drove the bearish trend, influenced by wetter weather forecasts for the western Corn Belt and expectations of ample global supplies. StoneX Group forecasted a 2026 US soybean harvest of 4.47 billion bushels. While the United States Department of Agriculture confirmed a private sale of 132,000 metric tons of soybeans to China, the purchase did not offset the downward pressure.

Geopolitical factors further impacted the market. Soybean prices declined alongside crude oil following reports of a potential deal between the United States and Iran to reopen the Strait of Hormuz, which affects biofuel production and vegetable oil markets. Traders are also monitoring the Russia-Ukraine war's effect on Black Sea exports, though expectations of another large regional harvest continue to weigh on prices.

Market participants are now looking toward the August 12 supply and demand report from the USDA. Additionally, a scheduled September meeting in Washington, D.C., between President Donald Trump and Chinese leader Xi Jinping is being monitored for its potential impact on trade tensions.
