Mexico’s refined fuel production surged 47% year-on-year in November 2025, reaching 1.203 million barrels per day. The increase was driven primarily by sharp gains in gasoline and diesel output, which rose 75% and 72% respectively. The Tula and Salina Cruz refineries led the expansion, while the Olmeca refinery in Dos Bocas posted its second consecutive monthly decline. The figures underscore the government’s continued emphasis on boosting domestic refining capacity to reduce reliance on fuel imports.
This strategy is aligned with broader energy sovereignty goals, which prioritize domestic processing of crude over exports. In line with this shift, Pemex’s crude oil exports fell 43% year-on-year in November to 539,000 barrels per day. However, the pivot comes at a cost. Refining remains structurally unprofitable for Pemex, and the reduction in crude exports limits its ability to generate foreign exchange revenues—long a critical source of liquidity for the state-owned company.
Despite increased output, Mexico’s refining system still falls short of meeting domestic demand. In November, estimated gasoline consumption stood at 830,000 barrels per day, while domestic production covered only 431,000 barrels. Diesel output similarly lagged behind demand. As a result, fuel imports remained substantial, with analysts estimating that nearly half of gasoline consumption continued to be met through imports. This highlights the persistent gap between policy ambitions and operational realities.
Refining remains structurally unprofitable for Pemex, even as it becomes central to national energy strategy.
Refinery utilization rates further illustrate the challenge. The National Refining System operated at an average of 65% capacity in November, with Dos Bocas at 61%. Analysts stress that achieving meaningful self-sufficiency would require utilization rates above 80% across legacy refineries and over 90% at Dos Bocas. Additional supply from Pemex’s Deer Park facility in Texas would also need to increase significantly to bridge the gap.
The financial implications are significant. As refining continues to generate losses, Pemex faces mounting pressure to balance its strategic role in national energy policy with its deteriorating fiscal position. Observers warn that without higher export revenues or substantial operational improvements, Pemex will remain dependent on federal support beyond 2027. The trade-off between energy independence and financial sustainability is becoming increasingly stark.
Moreover, questions around transparency and data reliability persist. Industry specialists have pointed to discrepancies between official performance metrics and observed refinery operations, particularly at Dos Bocas. Without clearer reporting and verifiable benchmarks, investor confidence in Pemex’s operational turnaround may remain limited.
The November data offers a snapshot of progress toward energy self-sufficiency—but also a reminder of the structural constraints facing Mexico’s refining ambitions. Unless utilization improves and efficiency gains materialize, the current approach risks deepening Pemex’s fiscal vulnerabilities without delivering full energy independence.
