Sandro Castro, grandson of late revolutionary leader Fidel Castro, has publicly slammed Cuba's president and questioned the island's socialist economic model, in a rare display of dissent from within the ruling family as the Trump administration ratchets up pressure on Havana and a de facto US oil embargo pushes the country into its worst energy crisis in living memory.

It is, by any measure, an unlikely platform for revolutionary reckoning: an Instagram account with 152,000 followers, built on dance videos, deadpan comedy and the kind of glamorous content that sits uneasily alongside the revolutionary austerity his family spent decades preaching.

Speaking in an interview with CNN, Castro said President Miguel Díaz-Canel "is not doing a good job", adding that reforms long overdue "have not been done well and today are harming us". He also pointed to daily hardships facing ordinary Cubans, saying that "there might not be electricity, no water… goods don't arrive,” a candid acknowledgement, from within the revolutionary establishment itself, of the depth of a crisis that has seen the national power grid collapse three times in March alone.

Castro went further still on the question of ideology. "Many people in Cuba think in capitalist terms… The majority of Cubans want capitalism, not communism," he said, while describing himself as a "revolutionary" focused on change and calling for an opening of the economic model and a reduction in bureaucracy. The remarks are striking coming from a member of the family that has defined Cuban socialism for more than six decades, and doubly so given the life Castro himself appears to be living.

His public profile sits in jarring contrast to the revolutionary austerity his grandfather made a point of imposing on an entire nation. According to the New York Times, the 33-year-old runs an upscale Havana cocktail bar serving gin and tonics and oven-baked pizzas, luxuries that mock the experience of most Cubans, whose average monthly salary runs to just under 7,000 pesos (around $18 at the informal exchange rate). His Instagram feed features fashionable Nike clothing, latest iPhones, luxury cars and beautiful women. A 2021 video in which he appeared behind the wheel of a Mercedes-Benz, the kind of vehicle long associated with the Miami exile lifestyle his grandfather disparaged, caused sufficient uproar that he felt compelled to clarify publicly: “The car in which I recorded the video belongs to an acquaintance of mine who lent it to me.”

Fidel Castro himself was not immune to such contradictions, being a man who extolled collective sacrifice while, by some accounts, rarely removing the pair of Rolex watches he wore on the same wrist.

The comments land at a particularly delicate moment. Washington has been tightening its grip on Cuba since January, when a US-led military operation removed Venezuelan president Nicolás Maduro, severing the island's dominant source of subsidised oil. The Trump administration subsequently threatened tariffs on any country supplying fuel to Cuba, effectively blockading the island, whose electric network relies on ageing oil-fired generators, and driving it to the brink of economic collapse. A Russian tanker carrying 730,000 barrels of crude oil arrived in Cuba this week in what analysts described as a temporary reprieve, enough to buy the government a matter of weeks before its fuel reserves run critically low again.

"Cuba is going to be next," President Donald Trump told reporters aboard Air Force One on March 29, in the latest threat suggesting the communist-run island would become Washington's next target once its military campaign against Iran had concluded.

Castro has not been immune to the political theatre of the moment. When Havana publicly confirmed it was engaged in negotiations with the White House, Castro marked the occasion by posting a comedy sketch featuring a distinctly tangerine-hued US president arriving at his door to propose buying the island.

Against that backdrop, backchannel talks between Washington and Havana are under way, with Secretary of State Marco Rubio, a son of Cuban immigrants who has long called for regime change, understood to be directing the US approach. Raúl Guillermo Rodríguez Castro, another Castro grandson, has been identified as a key interlocutor on the Cuban side, a role that highlights the starkly differing positions now visible within the broader family network: one cousin negotiating a potential transition behind closed doors, the other performing ironic skits about it on social media.

While Díaz-Canel has formally led the government since 2018, power is widely seen as concentrated among senior figures linked to Raúl Castro. Sandro Castro's broadside against the president may reflect those internal hierarchies as much as genuine reformist conviction.

Cuba's political establishment is not, it turns out, as monolithic as it once appeared. The cracks in the regime are still narrow, but they are visible now. Whether Castro's provocations, lavish and political alike, amount to meaningful dissent or merely elite repositioning ahead of a transition that Washington is actively trying to engineer remains an open question. On that, Sandro Castro, characteristically, is saying nothing.
