Mexican President López Obrador issued a new decree prohibiting GM corn for dough and tortillas and removing the expiry date for its ban on industrial and feed use. The decree also extends the glyphosate prohibition.
Washington had earlier said proposed changes were insufficient.
Removing the feed-use expiry date keeps long-term US feed-corn demand in Mexico uncertain. The move raises the odds of a USMCA trade dispute with the US, which is Mexico's main corn supplier.
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.
