A report prepared by World Perspectives for CropLife International estimates Mexico's planned ban on GM corn would raise Mexico's corn import costs by $4.4 billion over 10 years. It projects tortilla prices rising 30% in the first year and hurting GDP in both Mexico and the US.
A split into GM and non-GM grain handling streams would raise costs and add supply chain volatility for US corn exports to Mexico. The ban is a long-term risk to US corn demand, but the report itself does not change near-term flows.
