The United States has imposed an embargo on the Strait of Hormuz, a move that is already disrupting Cuba’s energy supply. The Caribbean island nation depends heavily on oil shipments that pass through the strategic waterway. With no immediate alternative routes, Cuban authorities are scrambling to keep fuel flowing.
Why the strait matters
The Strait of Hormuz is a narrow chokepoint between the Persian Gulf and the Gulf of Oman. About a fifth of the world’s oil moves through it daily. By blocking access, the US embargo effectively cuts off a key supply line for any country that relies on tanker traffic from the region. Cuba is one of them.
The embargo was announced without warning. Details of its scope and duration remain unclear. US officials have not publicly explained the reasoning behind the decision, though the move appears to target broader geopolitical leverage in the Middle East.
Cuba’s energy vulnerability
Cuba imports most of its oil. A significant portion arrives via ships that transit the Strait of Hormuz, often from suppliers like Iran and other Persian Gulf states. Without that crude, the island’s power plants and refineries face shortages. Gasoline deliveries have already slowed, and blackouts are becoming more frequent in some provinces.
The Cuban government has not issued a formal statement. But internal reports suggest officials are exploring emergency purchases from alternative markets in Africa and South America. Those options come with higher costs and longer shipping times.
This isn’t the first time Cuba has faced an energy crunch. The end of preferential oil deals with Venezuela in recent years left the country scrambling. Now the Hormuz embargo adds a new layer of strain.
What comes next
Diplomatic channels are quiet so far. There’s no indication the US will lift the embargo anytime soon. Cuban energy planners are left to calculate how many weeks of reserves remain. Without a quick resolution, the impact could ripple beyond fuel lines into food distribution, transportation, and basic services.
One unresolved question is whether Cuba can secure enough tanker capacity from non-Persian Gulf sources before winter demand peaks.
