More than 200 civil society groups and individuals asked President Lopez Obrador to cancel a draft presidential decree on glyphosate and genetically modified corn. The letter says the decree contradicts the government's stated goals to ban transgenic corn and phase out glyphosate.
The decree has not been issued.
A decree that loosens rules on GM corn and glyphosate would affect Mexico's corn sourcing and policy direction, but the outcome is uncertain and no price effect is clear yet.
After 1,623 past policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
