Mexican President Claudia Sheinbaum said she expects Congress to approve a ban on planting genetically modified corn early in 2025. The statement followed the USMCA panel ruling that Mexico's restrictions on US GM corn imports violate the trade agreement.

After 439 past neutral policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
