December corn futures fell to about $4.42 a bushel on Tuesday, their lowest since July 2 and well below mid-year highs above $5.50. Analysts attribute the decline to a surplus balance sheet, with USDA raising 2026/27 production to 16.03 billion bushels and US export demand down about 48% year to date.
Heavy supplies and weak export sales point to cheaper corn for feed buyers, with South American competition capping rallies. The next USDA supply report on Nov. 10 could reverse the slide if production estimates fall or Mexican purchases stay strong.
