Cuba's Energy and Mines Minister recently delivered a stark message: the country has completely run out of diesel and fuel oil.
This crisis is not a sudden event but the culmination of carefully orchestrated external pressures and internal vulnerabilities. The primary catalyst was a U.S. executive order issued on January 29, 2026. This order didn't just ban trade; it created a powerful deterrent by threatening tariffs on imports from any country that supplies oil to Cuba. This created significant legal and commercial risks for shippers and exporters, effectively creating a secondary blockade.
The immediate impact was severe. First, oil flows from Venezuela, which covered about a third of Cuba's needs in 2025, came to a halt. Second, Mexico, another crucial supplier, paused its shipments under the threat of U.S. tariffs. This double blow cut off the island's primary lifelines, leaving it scrambling for alternatives.
Compounding the problem were two other major factors. The global energy market saw a surge in diesel prices, with the 'crack spread'—a key indicator of refinery profit margins—widening dramatically. This made emergency spot purchases prohibitively expensive for cash-strapped Cuba. Internally, Cuba's energy infrastructure is extremely fragile. A refinery fire in February and two nationwide grid collapses in March revealed a system with almost no redundancy, meaning any fuel scarcity immediately translates into widespread blackouts.
Therefore, the minister's announcement is the logical endpoint of this chain of events. U.S. policy choked off supply, market conditions made alternatives unaffordable, and a weak domestic system was unable to withstand the shock. Without a near-term solution, such as new fuel shipments that can navigate the sanctions or humanitarian exemptions, Cuba faces a worsening energy crisis with profound implications for its people and economy.
- Crack Spread: A term for the price difference between a barrel of crude oil and the petroleum products (like gasoline and diesel) refined from it. A wider spread means higher refinery profits and more expensive fuel for consumers.
- OFAC (Office of Foreign Assets Control): A U.S. Treasury department that administers and enforces economic and trade sanctions.
- Executive Order: A directive issued by the President of the United States that manages operations of the federal government and has the force of law.
