The unexpectedly large corn inventory in Grain Stocks Report was bullish for cattle WASHINGTON, D.C. – Wednesday’s (Sept. 30) quarterly Grain Stocks report delivered a bearish surprise for corn, with September 1 inventories at 2.095 billion bushels, above all trade expectations. USDA also trimmed the 2025 corn crop by 57 million bushels to 16.694 billion , reducing harvested acres while leaving yield unchanged. Weather remains a factor, with heavy rain moving through the western Corn Belt this week and continuing to slow harvest. A much drier and warmer pattern is expected to move into the Plains and Midwest next week, potentially allowing harvest to accelerate.
