Mexican Senator Armando Rios Piter plans to introduce a bill that would shift Mexico's corn purchases from the US to Brazil and Argentina. The proposal responds to Trump's suggested tariff on Mexican goods to fund a border wall.
Mexico buys about 25% of US corn sales for the marketing year to date.
If enacted, the bill would remove a large share of US export demand, which is bearish for corn. Analysts note that switching suppliers would be logistically difficult, so the impact depends on passage.
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.
