US corn outright prices fell sharply Sept. 30, tracking losses on the Chicago Board of Trade after the USDA Grains Stocks report was released, which showed higher corn stocks than expected. Platts assessed October CIF New Orleans corn at $222.75/mt Sept. 30, down $7.95/mt from the previous assessment. November CIF New Orleans corn was assessed at $229.80/mt, down $8/mt, while December FOB Gulf corn was assessed at $236.52/mt, down $8.36/mt.

The US Department of Agriculture updated its Sept. 1 quarterly stocks report to 2.095 billion bushels of corn by the end of the 2025-26 marketing year (September-August), up from a preliminary 1.922 billion bushels from its preliminary report Sept. 11. The figure was above S&P Global Energy CERA’s estimate of 1.907 billion bushels and the trade expectation of 1.911 billion-1.918 billion bushels. The CBOT December (Z) futures contracts lost 21.25 cents during the business day to $5.0075/bu. The USDA reported that 787 million bushels of corn were held on-farm, while 1.31 billion bushels were stored off-farm.
