A field survey in eastern Heilongjiang found corn production of about 13 million tonnes, above the region’s usual 11–12 million tonnes, while soybean acreage and yields fell and output was estimated to decline by about 20%. Corn quality varied more widely, and delayed arrivals of ground-stored corn could concentrate supply pressure from mid-November onward; soybean farmers remained relatively reluctant to sell, while downstream buyers were cautious and sales were slow.
The larger corn crop and expected release of delayed supplies are bearish for corn, although farmer holding and higher costs may limit the downside. Lower soybean output and farmer reluctance to sell support soybean prices, but weak downstream buying and the risk of concentrated selling later could temper gains.
After 1,102 past bearish report events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.8% to +1.3%), and +0.0% over 20.
After 747 past bullish report events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.1%), and +0.8% over 20.
