More than twenty organizations, producers, Indigenous peoples and scientists asked Mexico's Supreme Court to take up the 13-year-old lawsuit against commercial planting of GM corn and issue a total ban. They also asked the court to rule that illegal contamination of native corn by GM varieties has occurred.
A court-ordered ban on GM corn planting would constrain Mexico's domestic corn supply options over time, but no ruling has been issued and the near-term price effect is small.
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.
