Bayer criticized Mexico's health regulator Cofepris for rejecting a GMO corn permit as unscientific. The rejection followed a broader planned prohibition on glyphosate-tolerant GMO crops.
Industry groups warned that a ban covering animal feed could raise food prices and risk a trade dispute with the United States.
A ban on imports of glyphosate-tolerant GMO corn that reaches feed use would cut demand for U.S. corn exports to Mexico, the largest market. That is bearish for corn prices and raises trade-dispute risk.
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.
