Record U.S. Corn Crop Sends Mexican Maize Prices Tumbling

A record 425 million tonne U.S. corn harvest has knocked Chicago futures 26% lower, feeding through to a 20% plunge in Mexican maize prices that piles pressure on local farmers.

Overview

  • The USDA forecasts a 425 million tonne U.S. corn crop for 2025–26, driven by drought-tolerant genetically modified seeds and federal support programs.
  • Chicago corn futures have tumbled by roughly 26%, sliding from $198 to $146 per tonne since February.
  • An 8% peso depreciation and lower international benchmarks have cut Mexican yellow-maize reference prices by 22% and white maize by 20%.
  • Mexico’s grain and oilseed imports reached 27.9 million tonnes in January–July 2025, with white corn shipments jumping to 658,000 tonnes and record volumes of sorghum, soybean meal and oats.
  • Mexican farmers, especially medium and large producers, face shrinking profits without guaranteed prices or risk-management tools even as feed and processing industries gain from cheaper inputs.
