Mexico published a decree on December 31 requiring the phase-out of glyphosate and GMO corn for human consumption by January 31, 2024. The government has not released implementation details, and it is unclear whether livestock feed corn is covered.
Mexico takes roughly 28-40 percent of Nebraska's corn exports.
If the ban were extended to feed corn, Mexico's large demand for U.S. corn, including DDGS-linked feed use, would shrink and pressure corn prices. Ambiguity keeps a risk premium on export demand.
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.
