Mexico Fuel Price Pact Runs to February 2027 as Diesel Cap Drops
MEXICO · ENERGY
Key Facts
—Signed at the palace: President Claudia Sheinbaum presided over the signing of a new extension of Mexico’s fuel price pact at the National Palace on 31 August, formalizing the deal reported ten days earlier.
—Six more months: The voluntary agreement with fuel retailers now runs until February 2027, the first time an explicit end date has been published for this renewal.
—The caps: Regular gasoline stays below 24 pesos per litre (about US$1.41), and diesel gets a reference ceiling of 27 pesos per litre (about US$1.59).
—A cheaper diesel cap: The new diesel reference is one peso below the 28 pesos (about US$1.64) agreed on an extraordinary basis in April, when global crude prices jumped.
—Voluntary, not law: The pact sets no binding maximum price, so drivers can still see variation between stations and regions.
—The goal: The government wants to stop international oil volatility from feeding into the basic food basket through transport costs.
Mexico’s fuel price pact was formally signed at the National Palace on 31 August, extending the voluntary scheme until February 2027 and lowering the diesel reference to 27 pesos a litre (about US$1.59).
From Announcement to Signature
When the renewal of the Mexico fuel price pact first surfaced on 21 August, the reports left two questions open: nobody could say which ministry had signed, and no calendar end date was published. Both gaps are now closed.
On 31 August, President Claudia Sheinbaum Pardo herself headed the signing ceremony at the National Palace, alongside the main representatives of the gasoline retail sector. The government and the retailers formalized what officials describe as a new prorogation of the national strategy to stabilize the price of regular gasoline and diesel.
The scheme now runs for six additional months, with its validity fixed until February 2027. We covered the initial announcement in our report on the six-month extension of Mexico’s gasoline price deal.
“We renewed the voluntary agreement with fuel retailers to fight inflation and high prices, in support of the economy and the wellbeing of Mexican families,” Sheinbaum said through her official channels.
What the New Caps Mean at the Pump
The pact ratifies reference ceilings for the two most consumed commercial fuels in the country. Regular gasoline, sold in Mexico as magna, stays below 24 pesos per litre (about US$1.41).
Diesel, the fuel of freight and public transport, gets a reference ceiling of 27 pesos per litre (about US$1.59). That is a reduction from the 28 pesos (about US$1.64) that had been agreed on an extraordinary basis in April to cushion the rise in international crude quotations.
The lower diesel cap matters beyond the pump. Diesel moves almost everything Mexicans buy, so its price feeds directly into the cost of the basic food basket. Cutting the reference by one peso signals that the government sees room to ease the pressure as global markets calm.

A Voluntary Pact with Fiscal Teeth
The agreement is strictly voluntary. No law forces a maximum price, so final tariffs can vary with each station’s operating costs, location and logistics. In the northern border strips, consumers pay less thanks to specific incentives, including a reduced value-added tax rate of 8 percent.
The strategy, which began in February 2025 for regular gasoline, does more than set reference prices. Negotiation tables between the private sector and federal authorities have added complementary measures: active use of the IEPS excise tax stimulus to absorb external oil swings, lower bank and card commissions for stations, simpler paperwork, and stronger operations against the illicit fuel market.
That fiscal cushion is the quiet engine of the pact. When crude rises, the finance ministry can shrink the IEPS take instead of letting the full increase reach the pump; when crude falls, the tax take recovers. The mechanism has kept Mexican pump prices among the most stable in the region through eighteen months of volatile markets.
Why the Timing Matters
The renewal lands at a sensitive moment for the Mexican economy. The central bank has cut its 2026 growth forecast to 1.1 percent, and keeping a lid on fuel costs is one of the few levers the government can pull quickly to protect household spending.
For the retailers, grouped in associations such as Onexpo, the pact offers predictability: stable volumes and fiscal relief in exchange for holding the reference prices. For the government, the signature ceremony converts a stopgap arrangement into a headline policy with a date, a face and a number attached.
The next checkpoint is February 2027. If international crude stays calm, expect the same ritual again; if markets turn, the IEPS cushion will be tested first.
Frequently Asked Questions
What is the Mexico fuel price pact?
It is a voluntary agreement between the federal government and fuel retailers to keep regular gasoline below 24 pesos per litre (about US$1.41) and diesel at a reference of 27 pesos per litre (about US$1.59), using tax stimulus and other measures to absorb global oil swings.
How long does the renewed pact run?
The extension signed on 31 August 2026 at the National Palace runs for six additional months, until February 2027. It is the first renewal of this round with an explicitly published end date.
Did the diesel cap change?
Yes. The diesel reference fell to 27 pesos per litre (about US$1.59) from the 28 pesos (about US$1.64) agreed on an extraordinary basis in April, when international crude prices had jumped.
