A University of Arkansas study surveyed Mexican consumers on the country's planned ban on genetically modified corn. More than half of respondents were unaware of the ban, and some supporters changed their view after learning about likely price increases and job losses.
A full GM corn ban would raise Mexican feed and food costs and threaten US corn exports, since Mexico is the second-largest buyer of US corn, which is bearish for US corn demand.
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.
