Cuba Crisis: US Oil Blockade Fuels Regime Change Fears & Diplomatic Exodus

Havana, Cuba – A growing sense of unease is settling over Havana’s diplomatic quarter, as ambassadors from countries traditionally aligned with the United States express frustration with Washington’s approach to Cuba, while simultaneously considering scaling back their missions. The island nation is grappling with a deepening crisis, compounded by a four-year economic downturn, soaring inflation, and the emigration of nearly 20% of its population.

The situation has been dramatically worsened by what the United States describes as an effort to facilitate political change, following a military operation against Venezuela – a key Cuban ally – in early January 2026. According to multiple diplomatic sources, the US administration is actively pursuing regime change in Havana.

More than five high-ranking officials from various countries have voiced concerns that the US charge d’affaires, Mike Hammer, has failed to articulate a clear plan beyond intensifying economic pressure on Cuba, specifically through restrictions on oil supplies. “There’s talk of human rights, and that this is the year Cuba changes – but little talk of what happens afterwards,” one official stated.

Rumours of high-level discussions in Mexico between representatives of the Cuban government – including Gen Alejandro Castro Espín, son of former President Raúl Castro – and US officials offer a glimmer of hope for a negotiated resolution, but as of February 15, 2026, no significant progress has been reported.

Comments made by US Secretary of State Marco Rubio at the Munich Security Conference this weekend have fueled cautious optimism among some diplomats. Rubio suggested that empowering the Cuban people with “more freedom, not just political freedom but economic freedom,” could be a viable path forward. However, this has not quelled concerns about a more forceful intervention.

Many diplomats fear that the US strategy hinges on deliberately crippling Cuba’s economy to incite widespread unrest, creating a pretext for intervention. “We’re trying to keep a cool head,” said one ambassador. “Embassies are built on planning for the unexpected – hopefully before it becomes expected,” added another.

The already precarious situation is being exacerbated by a critical fuel shortage, which is hindering the efforts of the UN World Food Programme (WFP) to provide humanitarian relief following Hurricane Melissa, which devastated the island last October. The WFP is now forced to prepare for a significantly larger crisis, with the availability of fresh produce in urban areas already declining. “We’re already seeing the impact in the availability of fresh produce in the cities,” said Étienne Labande, the WFP’s country director.

Diplomats are deeply concerned about the speed with which the fuel shortage could lead to widespread suffering. “It’s a matter of weeks,” one source warned. “The view is that people in rural villages like Viñales may be OK, but those in the cities would be at terrible risk.”

The current crisis stems from an executive order signed by former US President Donald Trump in January 2026, imposing tariffs on any country supplying Cuba with oil. Despite objections from China and Russia, Cuba’s traditional allies, the threat has proven effective. Even Mexico, which had become Cuba’s largest oil supplier after Venezuela, has suspended tanker shipments, although President Claudia Sheinbaum warned of a humanitarian disaster and sent 800 tons of aid.

During a reception at the US residence on January 28, 2026, Hammer referenced the decades-long US embargo on Cuba, telling guests that “The Cubans have complained for years about ‘the blockade’, but now there is going to be a real blockade.” He subsequently embarked on a tour of eastern Cuba, distributing US aid, during which he was met with protests from small groups of government supporters.

The impact of the oil blockade has been swift and severe. Three Canadian airlines suspended flights to Cuba this week due to a lack of aviation fuel, and two Russian airlines followed suit. All five carriers have initiated the repatriation of travellers. Canada, with approximately 750,000 visitors in 2025, represents Cuba’s largest tourism market, followed by Russia. The UK Foreign Office has adjusted its travel advice, recommending only essential travel to the island.

As the economic pressure mounts, Cubans are bracing for a prolonged period of hardship. “It is starting to feel like the 1962 missile crisis,” one resident remarked. “The sun was shining then too, and people went about their business, under a cloud of anxiety.”

The Cuban government has already closed universities, secondary schools, and non-essential state offices, and reduced public transportation to conserve resources. Adrian Rodriguez Suárez, a 22-year-old nuclear physics student at Havana University, has been instructed to return to his hometown of Holguín to continue his studies remotely.

Ordinary Cubans are turning to social media to express their concerns and offer assistance. One Facebook user inquired about the cancellation of weddings scheduled for March, while a motorcycle taxi driver offered free transportation to patients requiring chemotherapy, dialysis, or emergency care.

Amidst the hardship, some are finding ways to adapt. A man in La Lisa neighbourhood is manufacturing wood-burning stoves, selling single burners for $8 and double burners for $15.

Diplomats are actively preparing for a potential evacuation, questioning the purpose of maintaining a presence if they are unable to function effectively. “What is the point of us being here if You can’t work?” one asked. “We’re prepared, vigilant, and hoping common sense keeps winning a few rounds,” said another.

Even Havana’s vibrant nightlife is beginning to feel the effects. Yarini, a popular rooftop bar, was sparsely populated on a recent weeknight, with most patrons being foreign correspondents covering the unfolding crisis.
