Even with white corn up about 6% in four weeks, roughly MX$400 a ton, Mexico's tortilla prices should hold broadly steady, the agriculture ministry (SADER) said, according to a Sept. 23, 2026, Mexico Business News report. SADER says inventories are sufficient, with the Spring–Summer 2026 harvest adding supply.
The ministry's math: it takes about 700 kg of corn to make a ton of tortillas, and corn is around a third (34%) of the cost of a kilo. Each MX$100/t on corn therefore adds about MX$0.07/kg, so the recent move works out to about MX$0.28/kg.
Price-monitoring service SNIIM showed tortillas averaging about MX$24.52/kg in traditional shops nationally and MX$14.59/kg in supermarkets as of Sept. 21; some city shops sell for MX$16–17. Industry figures quoted by MBN, including Blanca Mejía of the Council for Traditional Tortilla, Homero López of the National Tortilla Council (CNT) and Sergio Jarquín, argued energy, labor, informal competitors and organized crime weigh on shops more than corn does.
For U.S. plants, the useful part is the corn-to-tortilla cost pass-through and the gap between official supply messaging and what shop owners report.
