USDA's October report raised US soybean harvested area by 740,000 acres but cut yield to 49.5 bushels per acre, below trade expectations, leaving production unchanged at a record 4.431 billion bushels. November CBOT soybean futures jumped nearly 3% on the report day and broke $10 the following day.
A surprise yield cut in a report with unchanged production signals tighter perceived supply, supporting soybean and meal prices.
