Mexico's proposed constitutional reform would prohibit the use and cultivation of genetically modified corn, following earlier decrees phasing out GM corn and glyphosate. The reform outlines gradual replacement of GM corn in industrial use and animal feed as non-GM options become available.
A gradual ban on GM corn in animal feed would shrink Mexico's demand for US yellow corn over time and could require non-GM supply, adding premium and logistics costs for feed buyers.
After 310 past bearish policy events, Corn moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.6% over 20.
