Mexico's oil, the latest concession to the Cuban regime

Mexican oil has become the last major concession from Washington to the Cuban regime: the White House allows Mexico to keep providing energy support while Trump warns that he expects gestures and negotiations from Havana in the short term.

A deliberate "permit" from Washington

The United States could pressure Claudia Sheinbaum to cut crude oil shipments to Cuba, but it has explicitly decided not to do so and allows Mexico to continue supplying the island. Officials cited by the American press admit that the current policy is to permit that flow, despite the rhetoric of "no oil, no money" that Trump repeats in public.

This apparent contradiction contains a cold logic: Washington does not want an immediate collapse of the Cuban electrical and social system, which could trigger another wave of migration to the United States and create a chaotic scenario within the island. That’s why it tolerates, and even needs, Mexico to do the dirty work of keeping the patient on life support while the White House manages the lever of time and sanctions

Oil as a Political Ultimatum

Trump has been clear in his message: "there will be no more oil or money for Cuba, zero," and "I recommend that they make an agreement before it's too late." This is not just bravado: he is signaling that the leeway currently provided – allowing Mexican oil – is temporary and contingent on the regime's decisions in the short term

That oil, therefore, is neither solidarity nor neutral pragmatism; it is a final concession: a grace period for Havana to decide whether it wants to negotiate a gradual, controlled, and limited transition with the United States, or if it prefers to remain entrenched at the risk of having the Mexican spigot turned off later. Trump is using the fuel not only as a sanction but also as a timer: every barrel that comes in from Mexico buys a few more weeks of electricity... and shortens the time to make a decision

Mexico: Humanitarian Firefighter or Supporter of the Regime

The Sheinbaum government insists that it has not increased shipments to Cuba and that it acts for commercial and “humanitarian” reasons, in line with López Obrador's tradition. However, the geopolitical reality is different: with Venezuela sidelined, Mexico has become the key supplier and, in effect, the main energy support for a dictatorship experiencing its worst crisis since the Special Period.

The paradox is evident: an emerging democratic power in the region, which prides itself on a principled foreign policy, is now appearing as a guarantor of survival for a regime that denies basic freedoms and violently suppresses protests. If Mexico does not reassess the political content of these shipments – their conditions, transparency, and the actual destination of the oil – it risks becoming an unwitting accomplice in the prolongation of the Cuban system, even if framed as humanitarian aid

Havana: Between Challenge and Dependence

Díaz-Canel's official discourse is one of defiance: he denies negotiating with Washington, insists on sovereignty to purchase fuel wherever he wants, and limits contacts with the U.S. to technical migration matters. However, behind that rhetoric, the regime is more dependent than ever: without Venezuelan oil, without external credit, and without substantial reforms, each ship that arrives from Mexico is a confession of fragility

There lies the core of the dilemma: the Cuban leadership wants Mexican oil to be an acquired right, a new structural subsidy, while Trump sees it as a one-time concession to force changes that are still not outlined publicly. If Havana misreads the situation and believes it can continue to buy time indefinitely, it may suddenly find itself facing a double squeeze: without Venezuela and, later on, without Mexico.

Last chance or useless extension?

Allowing Mexican oil may seem, at first glance, like a concession: it gives breathing room to the regime when it is weakest. However, Washington's calculation is more pragmatic: it is preferable to grant a few months of fuel in exchange for maintaining the ability to influence the situation, rather than pushing for a sudden collapse that no one can control.

Everything will depend on whether this concession leads to something tangible or merely represents a final, futile extension granted to an exhausted regime. The message is clear and no longer allows for naive interpretations. Mexican oil is not an indefinite lifeline, but rather a countdown. The Cuban government must understand this now or consciously accept that its inertia will drive the country toward a total collapse: energy, economic, and social. There will be no possible excuses or third parties to blame when the last light goes out.

The decision is no longer in Washington or Mexico City. It is in Havana. Either the regime correctly interprets the ultimatum, accepts that time has run out, and opens a real path that restores the future and dignity to Cubans, or it chooses to prolong the agony until there is nothing left to hold onto. What follows—overflowing migration, social breakdown, absolute state collapse—will be a direct consequence of that choice. It depends on them.
