Soybean futures saw mixed trading as recent Chinese flash sales provided support against a backdrop of lagging inspections, which remain 20% behind last year's pace. Meanwhile, Corn futures extended their slide to a fifth consecutive day, dropping a total of 23'2 cents ahead of Friday's USDA report. Wheat futures also faced pressure from weak export and inspection data, shedding over 67 cents from last week's highs as the spring harvest reached 86% completion. Elevated option open interest across all three grains indicates continued high participation in the markets.
