Uncertainty persists over whether Mexico will enforce its decree banning GM corn, which calls for phasing out GM corn and glyphosate by January 2024. US and trade groups continue talks with Mexican leaders, and US Agriculture Secretary Vilsack has warned of higher food costs.
Mexico imports about 17 million tonnes of GM corn annually, mainly from the US.
A enforced ban would remove a large export outlet for US corn, bearish US corn prices and bullish Mexican import costs, though the outcome remains unresolved.
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.
