An opinion piece argues that Mexico's decree banning GMO corn for human food, including tortillas and masa, does not restrict trade because most US corn exports are yellow feed corn. It notes the decree excludes animal feed and industrial uses.
The US and Canada have requested a USMCA trade panel over the ban.
The dispute centers on Mexico's roughly 18 MMT annual corn imports, most of which are GM yellow corn for feed; the decree does not currently restrict that flow, so the direct price effect is limited unless the panel changes the feed exemption.
After 31 past neutral geopolitics events, Corn moved a median -0.3% over 5 sessions (42% higher; middle half -2.3% to +1.1%), and +0.2% over 20.
