Mexico’s Cuba Oil Shipments Become A Diplomatic Flashpoint For Sheinbaum

Key Points

• Mexico’s fuel exports to Cuba are under fresh scrutiny as Washington targets Havana’s oil lifeline.
• Pemex disclosures show 2025 shipments via Gasolinas Bienestar, while lawmakers demand the full paperwork.
• With USMCA/TMEC talks nearing, a supply relationship is turning into a bilateral stress test.

Mexico’s Cuba policy has always carried a second message: how much independence Mexico can show while remaining deeply tied to the United States.

That balancing act is back, now centered on President Claudia Sheinbaum and the country’s continuing oil and fuel shipments to the island.

Sheinbaum says the deliveries are legal and humanitarian. Critics answer that good intentions are not a substitute for transparency.

They want the government to publish contract terms, pricing formulas, and payment records, especially while Pemex is financially strained and domestic priorities are tight.

Pemex filings have put numbers into the argument. The company has acknowledged exports to Cuba through its affiliate Gasolinas Bienestar.

Mexico’s oil shipments cushion Cuba amid sanctions

For January through September 2025, Pemex reported average shipments of about 17,200 barrels per day of crude plus roughly 2,000 barrels per day of refined products.

Pemex has also said transactions are peso-denominated and priced at prevailing market rates. But without public contracts and settlement details, opponents say Mexico cannot prove this is ordinary commerce.

The external shock is what raised the temperature. Cuba historically depended on Venezuela; 2025 deliveries from Caracas were reported at about 26,500 barrels per day, roughly a third of Cuba’s needs.

Since mid-December, those flows have been disrupted as President Donald Trump intensified efforts to block Venezuelan oil from reaching Cuba, openly framing fuel scarcity as political pressure.

In that setting, Mexico’s “steady” shipments matter more, because they help cushion the cutoff. In Washington, Congressman Carlos A.

Giménez has accused Mexico of sending “free” oil. U.S. Energy Secretary Chris Wright has said Washington has not asked Mexico to halt exports.

Why this matters abroad: it shows how sanctions, trade pacts, and energy logistics merge into leverage, and how a few tankers can shift bargaining power.
