Mexico has banned GM corn for human consumption and is phasing out its use in livestock feed and industrial uses, prompting the US to invoke the USMCA dispute process. Canada has backed the US position that Mexico's biotech stance is not scientifically based.
Mexico buys large volumes of US corn, so the dispute creates uncertainty over future export demand and possible tariffs, which supports a cautious or bearish outlook for US corn.
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.
