A CoBank economist writes that Mexico's GM corn ban, expected in 2024, is already slowing approval of biotech traits in Mexico. Some seed companies are reluctant to push unapproved traits there.
A World Perspectives study commissioned by CropLife America estimates the ban could add $4.4 billion to Mexico's corn import costs.
Slower trait approvals and the risk of costly segregation could reduce U.S. corn competitiveness in Mexico and raise Mexican import costs over time, which is a bearish factor for U.S. corn export demand.
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.
