Mexico Says 6% White Corn Increase Does Not Justify Higher Tortilla Prices
Mexico’s white corn price rose 6%, or 400 pesos per tonne, over four weeks due to seasonal supply and demand factors. The government says inventories and the Spring-Summer 2026 harvest should keep tortilla supplies and prices stable.
Seasonal increase adds pressure to tortilla costs
The price of white corn in Mexico increased 6% over four weeks, equivalent to 400 pesos per tonne, as seasonal supply and demand factors tightened the market. Despite the increase, the Ministry of Agriculture and Rural Development said the country has sufficient inventories to meet demand from the tortilla industry and that there is no justification for raising prices of the staple food.
According to the ministry’s calculation, the 400-peso adjustment increases the cost of producing a kilogram of tortillas by only 0.28 pesos. Every increase of 100 pesos per tonne of corn adds about 0.07 pesos to the cost per kilogram of tortillas. The government described the latest impact as marginal within the industry’s overall operating balance, although processors still face a higher bill for their principal agricultural input.
Corn accounts for at least 34% of production cost
The ministry said corn represents at least 34% of the total cost of producing a kilogram of tortillas. Under the traditional nixtamalization process, one tonne of grain yields approximately 1.8 tonnes of dough and around 1.45 tonnes of tortillas. Producers therefore require an average of about 700 kilograms of corn to make one tonne of tortillas.
These conversion rates explain the government’s estimate that a 6% increase in grain prices should not translate into an equivalent increase at the retail counter. Other expenses, including labor, energy, rent and distribution, make up most of the remaining production cost. The ministry also estimated that an average establishment producing 250 kilograms per day earns a profit of 0.59 pesos for every peso invested. That calculation underpins its view that tortilla businesses can absorb the limited corn-cost increase without an immediate retail adjustment.
Retail prices vary widely across Mexico
Data from the National Market Information and Integration System, cited by Crónica, showed an average tortilla price of 14.59 pesos per kilogram in supermarkets as of September 21. Prices at traditional tortilla shops were between 16 and 17 pesos per kilogram, mainly in Xalapa, Veracruz, Puebla and Tlaxcala, while the national average for these outlets stood at 24.52 pesos. The gap highlights the importance of sales channels and local operating costs in determining what consumers pay.
The start of Mexico’s Spring-Summer 2026 harvest is expected to increase domestic white corn availability substantially and help stabilize costs in the short term. The timing is important for millers and tortilla producers after the seasonal increase in grain prices. Existing inventories provide a buffer until more supplies from the new crop reach the market.
Government seeks shorter supply chains
Under the Fair Price system for organizing white corn production and marketing, the Agriculture Ministry is working with the dough and tortilla industry to strengthen coordination across the value chain and reduce intermediary costs. The program aims to let processors purchase grain directly from warehouses in producing regions, while limiting speculation and supporting stable consumer prices.
The ministry recently registered 24,972 producers in Sinaloa for an incentive covering white corn production and marketing from the Autumn-Winter 2025-2026 cycle. The government allocated 2.8 billion pesos to the measure. For growers, the support is intended to reinforce production and commercialization; for processors, inventories, the incoming harvest and more direct procurement could moderate the effect of short-term grain-price increases.
