Cuba now has just 15 to 20 days of oil reserves left as the Trump administration’s pressure campaign cuts off its main sources of imported fuel and drives a deepening energy crisis in Havana. According to industry tracking data, the island’s limited stored crude and last small deliveries give it only a few weeks of fuel at current consumption levels, raising the specter of prolonged blackouts, transportation paralysis, and severe economic disruption in a country already suffering chronic shortages and power failures.

The crisis stems from the effective halt of Venezuelan oil exports, which for decades supplied a large share of Cuba’s energy needs under heavily subsidized arrangements. Venezuelan shipments have stopped amid U.S. sanctions and enforcement actions that have blocked tankers headed for Cuban ports, depriving Havana of a critical lifeline. In addition, Mexico, once a key secondary supplier, has paused or sharply cut shipments, with its president describing the decision as “sovereign” even as deliveries have fallen to a fraction of past levels.

Cuba’s state energy sector has acknowledged that strategic reserves are critically low, and officials warn that without immediate alternative supplies, widespread blackouts already affecting the island could become constant. Cuba depends on imported oil for electricity generation, transportation fuel, agriculture, and basic industrial activity, and with Venezuelan crude offline and Mexican deliveries shrinking, Havana faces one of the most acute energy crunches in years.

The Trump administration has framed its approach as part of broader pressure on both Caracas and Havana, arguing that cutting off subsidized oil underpins efforts to deprive authoritarian regimes of resources that sustain them and their regional influence. Supporters of the policy say it delivers a long-overdue blow to the Castro-Maduro axis, forcing governments that have relied on subsidized energy to confront economic realities.

With reserves dwindling and limited alternative suppliers available, the energy situation in Cuba is tightening dramatically. Officials privately acknowledge the situation is dire, and blackouts are expected to intensify within days.
