Gruma's Monopolistic Grip on Mexico's Corn Flour Market Raises Concerns

In a preliminary decision, Mexico's antitrust watchdog, Cofece, has concluded that the country's corn flour and tortilla-maker Gruma holds a dominant position in the market, allowing it to dictate higher prices. This finding has significant implications for the Mexican economy and the well-being of consumers, as corn tortillas are a staple in the national diet.

Uncovering the Lack of Competition in Mexico's Corn Flour Sector

Gruma's Outsized Market Share

The Cofece investigation revealed that Gruma controls a much larger share of the corn flour market than any of its competitors, reaching between 22 and 80 times the size of its largest rival across eight regions in the country. This level of market dominance raises concerns about the company's ability to influence prices and limit consumer choice.

Pricing Disparities and Anticompetitive Practices

The watchdog's findings also showed that Gruma's average corn flour prices are nearly 10% higher than those of its national competitors. Additionally, the company has been accused of employing commercial strategies that make it difficult for tortilla makers to switch suppliers, further entrenching its position in the market.

Implications for the Mexican Economy and Consumers

Corn tortillas are a staple in the Mexican diet, consumed daily by 70% of the population. The cost of tortillas accounts for approximately 6% of household food budgets, making it a significant factor in the overall cost of living. Cofece's preliminary decision highlights the need to address the lack of competition in this crucial food segment, which has far-reaching implications for the country's economy and the well-being of its citizens.

Cofece's Proposed Remedies

To restore competition and curb prices, Cofece has recommended that Gruma sell five of its corn flour plants and halt certain commercial strategies that hinder tortilla makers from switching suppliers. These measures aim to level the playing field and provide consumers with more options and competitive pricing.

Gruma's Response and the Path Forward

Gruma has stated that it has fully cooperated with Cofece's investigation and has always operated within the bounds of the law. However, the company acknowledges the preliminary nature of the ruling and the need to await the final decision by Cofece's governing body.As the antitrust agency continues its review and Gruma prepares its arguments, the outcome of this case will have significant implications for the Mexican corn flour and tortilla market. The resolution of this issue will determine whether consumers can expect more competitive pricing and a greater diversity of suppliers in this essential food segment.
