Soybean futures on the Chicago Mercantile Exchange neared a four-week high due to strong export demand and China's planned anti-dumping investigation into Canadian canola imports, indicating potential shifts in oilseed supply sources. U.S. soybean crop ratings likely declined due to dry conditions, while the USDA reported high export inspections and significant sales to China. Wheat and corn futures also rose amid technical trading, concerns over EU and Russian production, and anticipated lower Midwest crop estimates. Warm weather in the Midwest is reducing early frost concerns, but dry conditions persist across 20% to 25% of the U.S. corn crop, particularly in the Ohio Valley and the far northwest Midwest.
