Mexico's commitments for US corn stood at 9.023 million tonnes as of October 22, down 3.7 million tonnes from the previous year's record pace, a 31% drop in the 2026/27 marketing year. Mexican output is forecast at 23.5 million tonnes against consumption of 48.2 million tonnes, and Brazilian corn priced about $6/t cheaper is taking share.
Lower Mexican purchases remove a major source of US corn export demand, which is bearish for US corn prices. Competition from cheaper Brazilian corn reinforces the weaker US export outlook.
After 683 past bearish trade events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.7% to +1.6%), and +0.3% over 20.
