Agricultural markets face downward pressure across the board as global supply dynamics weigh on prices. Soybean futures trade lower following the Brazilian election, with the January contract dropping 29'2 to 1239'0 amid shifting expectations for Chinese imports. Corn futures slide on harvest pressure and recent USDA crop data adjustments, pushing the December contract to 450'2, though option open interest on the call side climbs above 600,000. Wheat futures extend their slide to an eighth consecutive session, falling 12'4 to 612'4 as optimism around a Black Sea peace deal and plentiful global supplies continue to cap rallies.
