Cuba’s deepening humanitarian and economic crisis is poised to worsen as the United States escalates pressure on Venezuela, the island’s most critical energy lifeline. With Venezuelan oil exports increasingly disrupted by US seizures and sanctions enforcement, Cuban officials and analysts warn that a sharp drop in shipments could trigger an outright collapse of the Cuban economy.
Cubans are already enduring severe hardship. Food shortages are widespread, electricity blackouts last up to 18 hours a day in some regions, diseases such as dengue and chikungunya are spreading, and many people are sleeping outdoors to escape the heat in homes without power. Since 2020, more than 2.7 million people—roughly a quarter of the population—have fled the island, making the exodus one of the largest peacetime migrations in the Western Hemisphere.
That crisis now faces a new shock. Washington has intensified actions against Venezuelan President Nicolás Maduro’s government, including the seizure of sanctioned oil tankers and what officials describe as a partial blockade. About 70 percent of Venezuela’s crude exports are carried by the targeted vessels. One tanker already seized by the US was transporting nearly two million barrels of oil, highlighting the scale of disruption facing Caracas—and by extension, Havana.
Venezuela has been Cuba’s economic backbone for more than two decades. After Hugo Chávez came to power in 1999, the two countries forged a strategic alliance that saw Venezuela ship as much as 100,000 barrels of oil a day to Cuba at heavily subsidized rates. In exchange, Havana sent doctors, sports trainers, and intelligence personnel to Venezuela. While oil shipments have since fallen to roughly 30,000 barrels per day, they still account for about 40 percent of Cuba’s imported oil and remain essential for electricity generation, transport, and small businesses.
“If Venezuelan oil shipments stop or sharply decline, it would be the collapse of the Cuban economy, no question about it,” said Jorge Piñón, an expert on Cuban-Venezuelan energy ties at the University of Texas at Austin. Economists warn that even a partial reduction could prove catastrophic given Cuba’s lack of reserves and limited alternative suppliers.
The growing pressure on Caracas has also brought a military dimension. The US has increased its presence in the Caribbean, carried out airstrikes on vessels allegedly linked to Venezuelan drug trafficking, and issued warnings that have included threats of direct military action. Cuban President Miguel Díaz-Canel condemned the seizure of Venezuelan oil tankers, likening it to piracy and accusing Washington of operating without rules.
Cuba’s reliance on Venezuela has also translated into political and security commitments. Cuban intelligence operatives remain deeply embedded in Venezuela, where former officials say they play a key role in protecting Maduro, purging disloyal military officers, and preventing coups. Former US diplomat Thomas A. Shannon Jr. said Havana is doing everything possible to ensure Maduro’s survival, calling it Cuba’s greatest strategic priority.
Inside Cuba, the economic picture continues to deteriorate. The economy has contracted by about 15 percent since 2018, inflation has surged nearly 450 percent, and the peso has collapsed on the black market. Nearly 90 percent of Cubans live in extreme poverty, and 70 percent go without at least one meal a day, according to the Social Rights Observatory. The same polling found that 78 percent of respondents intend to leave the country.
Ordinary Cubans describe daily life as a struggle for survival. Hospitals and schools are failing, garbage is piling up, water access is intermittent, and children are increasingly absent from classrooms. Those with access to dollars from relatives abroad can scrape by, but state workers earning only a few dollars a month in local currency are being crushed by inflation.
Even members of Cuba’s tightly controlled National Assembly have begun to publicly acknowledge the severity of the situation. Díaz-Canel recently warned that without economic efficiency and stability, sovereignty itself is at risk. Yet resistance remains within the government to significantly expanding the private sector, one of the few areas showing signs of resilience.
Analysts say the loss of Venezuelan oil could push Cuba past a breaking point. While Havana produces a small amount of domestic crude and receives limited shipments from Mexico and Russia, none can replace Venezuelan supply at scale. “You could say it’s as bad as it can get,” said economist Ricardo Torres Pérez, “but we also know it can get worse.”
As US pressure on Maduro intensifies, Cuba finds itself dangerously exposed, bound to an ally whose own economic and political survival is increasingly uncertain. For millions of Cubans already living on the edge, the coming months may determine whether the crisis deepens into an irreversible collapse.
