NextFin News - In a move that significantly heightens the economic isolation of Havana, the Mexican government has confirmed a suspension of oil shipments to Cuba. The decision, executed by the state-owned oil giant Petróleos Mexicanos (Pemex), marks a critical turning point in regional energy dynamics. According to ABC News, Mexican President Claudia Sheinbaum stated on Tuesday that the pause was a "sovereign decision" and part of general fluctuations in supply, though she notably declined to deny that the suspension was influenced by the shifting geopolitical landscape in Washington.
The suspension comes at a time of unprecedented pressure from U.S. President Trump, who has intensified efforts to dismantle the remaining socialist administrations in the Caribbean. Following the U.S. military operation that deposed Venezuelan President Nicolás Maduro earlier this month, U.S. President Trump has publicly vowed to cut off all remaining lifelines to the Cuban government. On Tuesday, U.S. President Trump told reporters that Cuba is a "nation that is very close to failing," citing the total loss of subsidized oil and financial support from its former primary benefactor, Venezuela.
The logistical details of the suspension are stark. According to Bloomberg, Pemex removed a scheduled cargo of crude oil from its January manifest that was originally slated to load in mid-month aboard the vessel Swift Galaxy. This shipment was intended to provide a vital buffer for Cuba’s aging power grid, which has suffered from chronic blackouts and fuel shortages. Data from Pemex indicates that Mexico had been shipping approximately 20,000 barrels of oil per day to the island throughout 2025, a figure that began to dwindle following a high-profile visit to Mexico City by U.S. Secretary of State Marco Rubio in late 2025.
The causes behind this policy shift are rooted in a complex "tightrope" act performed by the Sheinbaum administration. While Mexico has historically maintained a policy of non-intervention and solidarity with Cuba, the current reality of U.S.-Mexico relations is dominated by the threat of unilateral U.S. action. U.S. President Trump has recently threatened military strikes against Mexican drug cartels and hinted at severe trade repercussions if Mexico does not align with Washington’s regional security and foreign policy goals. Analysts suggest that Sheinbaum is prioritizing the stability of the United States-Mexico-Canada Agreement (USMCA) and border security cooperation over its traditional ideological ties to Havana.
The impact on Cuba is expected to be catastrophic. With Venezuela’s supply lines severed by the U.S. blockade and Mexico now pausing its deliveries, Cuba has lost its two largest energy suppliers. This leaves the island almost entirely dependent on sporadic shipments from Russia or potential overtures from China. In Havana, the news has already triggered panic, with reports of gas lines stretching for blocks as citizens anticipate a total collapse of the transportation and energy sectors. According to the Associated Press, energy experts like Jorge Piñon of the University of Texas have noted that Cuba’s domestic production is insufficient to meet even 40% of its basic needs, making the Mexican suspension a potential death knell for the current administration in Havana.
Looking forward, the trend suggests a total realignment of Latin American energy politics under the shadow of U.S. hegemony. If Mexico’s "temporary" pause becomes permanent, it will likely accelerate the collapse of the Cuban economy, fulfilling the Trump administration's stated goal of regime change by the end of 2026. However, this vacuum may also invite deeper involvement from extra-regional powers. As Mexico retreats, Havana may look toward Beijing for emergency credit lines or energy swaps, potentially turning the Caribbean into a renewed theater of Great Power competition. For Mexico, the challenge remains whether it can maintain the appearance of sovereignty while effectively operating as a functional partner in U.S. President Trump’s regional containment strategy.
