Mexico Seeks to Maintain Gasoline Prices Stable

Mexico is balancing global oil price volatility with a state-led strategy to stabilize domestic fuel costs by scaling production at the Olmeca refinery and increasing IEPS fiscal subsidies. This transition toward energy self-sufficiency has reduced diesel imports to historic lows and enabled the resumption of refined product exports, directly impacting the logistics, freight, and energy sectors. However, the rising fiscal cost of maintaining price caps near MX$24/L for gasoline amid Brent crude surpassing US$100/b highlights a growing tension between national energy policy and international market pressures.

Mexico’s gasoline market is entering a period of tension between global price pressures and domestic supply gains, as the government seeks to stabilize fuel costs while increasing refining output and reducing import dependence.

Recent international developments, particularly the escalation of conflict in the Middle East, have pushed crude prices higher, directly impacting fuel markets worldwide. Brent crude has surpassed the US$100/b threshold in recent days, creating upward pressure on gasoline and diesel prices. In response, the Mexican government has intensified its price-containment strategy, combining fiscal incentives with agreements across the downstream sector.

According to recent policy actions, authorities have reinforced price caps with fuel distributors, aiming to keep regular gasoline near MX$24/L. At the same time, the government has expanded fiscal stimuli through the Special Tax on Production and Services (IEPS), effectively absorbing part of the increase in international oil prices. These measures have helped limit price volatility at the pump, though at a growing fiscal cost.

The pressure is particularly acute in diesel markets, where subsidies have reached over 70% of the IEPS component to prevent prices from exceeding MX$28/L to MX$30/L. Diesel pricing remains critical due to its direct impact on logistics, freight, and inflation.

At the same time, Mexico’s refining system is undergoing a structural shift that is beginning to reshape fuel supply dynamics. The ramp-up of the Olmeca refinery in Dos Bocas has significantly increased domestic production of refined products, particularly diesel. Recent data indicates that the refinery now contributes more than a quarter of national diesel supply, marking a rapid transition from zero output to a central role in the market.

This increase in refining capacity is already translating into tangible market outcomes. Diesel imports have dropped to their lowest levels in nearly two decades, while PEMEX has resumed exports of refined products, including diesel, for the first time in years. Export volumes reached more than 60Mb/d in early 2026, generating over US$150 million in external sales.

Government messaging has emphasized that these developments are part of a broader strategy to achieve fuel self-sufficiency and shield domestic markets from international volatility. Energy authorities have linked stable gasoline prices to increased domestic production and improved refining utilization, reinforcing the role of infrastructure investments in price stabilization.

However, the relationship between refining output and retail prices remains complex. While higher domestic production reduces reliance on imported fuels—particularly from the US Gulf Coast—Mexico is still exposed to global crude price fluctuations. This is because gasoline prices are influenced not only by refining capacity but also by international benchmarks, logistics costs, and fiscal policy.

The current pricing strategy reflects a deliberate policy choice. By maintaining gasoline prices at politically and socially acceptable levels, the government is effectively redistributing costs across the system. Consumers benefit from relative price stability, while the government absorbs revenue losses through reduced IEPS collection, and industry participants adjust margins to align with agreed price bands.

This balancing act is becoming more challenging as global oil markets grow increasingly volatile. The recent surge in crude prices linked to geopolitical tensions has tested the limits of Mexico’s price-control mechanisms. Although higher oil prices can boost public revenues through crude exports, these gains are partially offset by the fiscal burden of subsidies.

At the same time, increased refining capacity introduces new operational and financial variables. Higher utilization rates across the National Refining System require sustained crude supply, maintenance efficiency, and logistical coordination. Any disruption in these areas could affect output levels and, indirectly, domestic fuel availability.
