Fuel blockade deepens Cuba's crisis as U.S. pressure tightens

Since January 2026, a U.S. order threatening tariffs on countries that supply oil to Cuba has cut the island’s fuel imports. The shortage has hit power, healthcare, food and water. UN human rights experts call it "energy starvation"; Washington says Cuba threatens U.S. security. Havana has turned to solar power and market reforms, but structural weaknesses remain.

The brief in 7 cards

  1. Context1 / 7
    • An editorial examines the U.S. embargo on Cuba, which has tightened sharply in 2026.
    • On 29 January 2026, U.S. President Donald Trump signed an executive order under the International Emergency Economic Powers Act (IEEPA) allowing extra tariffs on goods from any country that directly or indirectly supplies oil to Cuba. It describes the Cuban government as an "extraordinary threat" to U.S. national security.
    • This came after Venezuelan oil shipments to Cuba stopped, following the U.S. operation that removed President Nicolás Maduro in January 2026.
    • In May 2026, three UN Special Rapporteurs described the measures as "energy starvation", and said they undermine a wide range of human rights.
    • In June 2026, Cuba's National Assembly approved 176 economic reforms, the island's largest economic shake-up in six decades.

    From embargo to blockade

    The table below sets out how U.S. restrictions on Cuba have built up.

    YearMeasure
    1959Cuban Revolution; nationalisation of U.S.-owned assets follows
    1960U.S. bans most exports to Cuba, except food and medicine
    1962Embargo expanded to cover almost all trade
    1992Cuban Democracy Act; the UN General Assembly begins its annual resolutions against the embargo
    1996Helms-Burton Act codifies the embargo and penalises foreign firms dealing in confiscated property
    2026Executive order targets third countries that supply oil to Cuba
    • Why Cuba calls it el bloqueo, the blockade. The measures reach beyond U.S.-Cuba trade into shipping, banking and companies in third countries, which Havana says makes them a blockade rather than a bilateral embargo.
    • Opposition at the UN. The General Assembly has adopted a resolution against the embargo every year since 1992. In October 2025 the vote was 165 in favour, 7 against and 12 abstentions, down from 187-2-1 in 2024, as some European and Latin American states shifted. These resolutions are not binding.

    The two positions

    This card sets out the documented positions without adjudicating between them.

    • The U.S. position. The executive order accuses Cuba of aligning with countries and groups hostile to the United States, including Russia, China and Iran. Washington says the pressure is aimed at political and economic change, and urges Havana to respect human rights.
    • Cuba's position. Havana says its political system is a matter of national sovereignty. Its Foreign Minister called the January order an act of aggression.
    • The UN experts' view. The rapporteurs called the fuel blockade unlawful, and urged Washington to stop using such measures as a coercive tool.
    • The legal debate. Critics argue that extraterritorial sanctions violate freedom of trade and navigation. The editorial adds that any threat or use of force against Cuba's political independence would breach Article 2(4) of the UN Charter, which bars the threat or use of force against any state's territorial integrity or political independence.
  4. Key highlights4 / 7
    • Energy. Cuba has said its fuel supply fell by about 90% after it could not import oil for over three months, causing long daily blackouts and rationing.
    • Health. UN experts cited reports of a backlog of more than 96,000 surgeries, including about 11,000 for children, and delays in immunising infants.
    • Food and water. Fuel scarcity disrupts transport, refrigeration and farming. Power cuts stop water pumps, which shows how energy, water and health are linked.
    • The economy. Tourism and other foreign-exchange earners have suffered, and economic decline has driven large-scale emigration.
    • Not only sanctions. The editorial argues that the crisis also reflects domestic weaknesses: low productivity, weak investment, ageing power plants and scarce foreign exchange.
  5. Key concepts5 / 7

    1. Why was Cuba so vulnerable?

    Under a 2000 agreement between Hugo Chávez and Fidel Castro, Venezuela provided subsidised oil while Cuba sent doctors and other professionals. As Venezuela's output fell the shipments shrank, and they stopped altogether in January 2026. Mexico's state oil firm Pemex had been shipping nearly 20,000 barrels a day in 2025, but paused some shipments under U.S. pressure.

    2. How is Cuba responding?

    Cuba says it has installed 1,418 MW of solar capacity across 144 plants, and expects to exceed 1,500 MW by the end of 2026. Renewables provide about 21% of its electricity. China has been a key partner, supplying solar parks and equipment.

    3. What are the limits of solar?

    Solar produces nothing after sunset. With only 50 MW of battery storage installed so far, Cuba still depends on ageing thermal plants for night-time power and for grid stability.

    4. What did the June reforms change?

    The 176 measures allow larger private firms, let Cuban and foreign investors buy stakes in state companies, open fuel trade to private investment, remove taxes on solar equipment, and permit foreign-currency accounts.

    5. What is the wider geopolitical effect?

    The editorial argues that U.S. pressure may push Cuba closer to China and Russia, sharpening great-power competition in the Caribbean.

  6. Way forward6 / 7

    These are the editorial's suggestions, not agreed policy.

    • Protect humanitarian access to food, medicine, fuel and medical equipment, regardless of political differences.
    • Build energy resilience through solar with battery storage, grid modernisation and a wider range of fuel suppliers.
    • Pursue domestic reform in agriculture, private investment and tourism, alongside external diplomacy.
    • Seek a diplomatic solution grounded in sovereignty, non-intervention and confidence-building.

Practice questions

  1. With reference to the U.S. embargo on Cuba, consider the following statements: 1. The UN General Assembly has adopted a resolution against the embargo every year since 1992. 2. General Assembly resolutions on the embargo are legally binding on member states. 3. The Helms-Burton Act, 1996 penalises foreign firms dealing in property confiscated after the Cuban Revolution. Which of the statements given above are correct?

    1. 1 and 2 only
    2. 1 and 3 only
    3. 2 and 3 only
    4. 1, 2 and 3
    Show answer

    Answer: B. Statements 1 and 3 are correct. Statement 2 is wrong: General Assembly resolutions are recommendations and carry no legal obligation, which is why the embargo has continued despite a resolution against it every year since 1992. Only Security Council decisions under Chapter VII bind member states.

Mains practice

Answer-writing practice on this article. Attempt it first, then open the hints.

  1. GS2 · 250 words

    Examine the legality and effectiveness of unilateral, extraterritorial sanctions, with reference to the U.S. measures on Cuba.

    Show hints
    1. Distinguish a bilateral embargo from measures that reach third countries through shipping, banking and secondary tariffs, which is what makes them extraterritorial.
    2. Set out the legal objections, covering freedom of trade and navigation, sovereignty, and the prohibition on the threat or use of force in Article 2(4) of the UN Charter.
    3. Weigh the annual General Assembly resolutions against their non-binding character, and what that reveals about enforcement in international law.
    4. Assess effectiveness honestly: decades of pressure have not produced the political change sought, while humanitarian costs have been documented.
    5. Conclude on the stated security rationale, and on whether coercive economic measures are the instrument best suited to it.
  2. GS2 · 250 words

    "Cuba’s crisis shows how energy dependence can become a strategic vulnerability." Discuss, and draw lessons for energy-importing developing countries.

    Show hints
    1. Explain the dependence itself, built on a single subsidised supplier under a bilateral arrangement, and what happened when that supplier stopped.
    2. Trace how a fuel shortage propagates, through blackouts into water pumping, refrigeration, transport and hospital capacity.
    3. Assess the renewable response, noting that solar capacity without storage cannot cover the hours when demand persists.
    4. Draw the general lesson on diversifying suppliers, holding reserves and avoiding concessional arrangements that are politically contingent.
    5. Conclude that external shocks expose domestic weaknesses rather than create them, so resilience requires investment and reform alongside diplomacy.
