The U.S. Grains & BioProducts Council says Mexico repealed its GM corn restrictions in February 2025, keeping the Mexican market open for U.S. corn. The change followed a USMCA panel ruling in December 2024 that found Mexico's measures lacked scientific basis.
U.S. corn exports to Mexico reached a record 23.5 million metric tons in MY 2023/24.
Secure access to Mexico, the largest buyer of U.S. corn, supports steady export demand and underpins U.S. corn prices. The news is a reaffirmation of existing conditions rather than a new shift in flows.
After 729 past bullish trade events, Corn moved a median +0.4% over 5 sessions (56% higher; middle half -1.1% to +1.8%), and +0.5% over 20.
