Agriculture Secretary Tom Vilsack said on December 15 that the Biden administration is ready to challenge Mexico under USMCA rules unless it revises a decree that would ban GM corn imports from 2024. Two dozen farm-state senators urged USTR Katherine Tai to pursue dispute resolution.
They estimated the ban would shut down 83% of US corn sales to Mexico.
An 83% loss of US corn sales to Mexico would be a major demand shock for US corn exports. The threat of a formal trade challenge raises the risk of a prolonged dispute that could weigh on prices.
After 683 past bearish trade events, Corn moved a median -0.2% over 5 sessions (47% higher; middle half -1.7% to +1.6%), and +0.3% over 20.
