Cuba's Third Nationwide Blackout in Six Months
UN Secretary-General Warns of Possible "Collapse"

← Back to Latin America News

Between July 6 and 7, Cuba was hit by a nationwide blackout — the third in the past six months. In Havana, power cuts stretched beyond 15 hours a day, and in some rural areas outages reportedly exceeded 70 hours. This makes eight nationwide blackouts since October 2024. UN Secretary-General António Guterres warned, with unusual force, that the situation is "extremely serious and could deteriorate or collapse." Cuba's compound crisis under the fuel blockade is entering a new phase.

What happened

The direct cause of the blackout is a lack of fuel. In February 2026, the Trump administration issued an executive order fully cutting off oil tankers to Cuba, and applied tariff pressure on third countries supplying the island with oil. By May, Cuba's fuel reserves were reported to have run dry. The aging power plants had long been operating on a knife's edge, but once the fuel itself stopped arriving, the entire grid fell into a cycle of shutdown and restoration.

Going a step further, the UN pointed out that "the oil blockade is blocking the entry of 170 containers of humanitarian aid." Shipments including food and medicine have been halted, and experts at the Office of the UN High Commissioner for Human Rights (OHCHR) have condemned the executive order as a "serious violation of international law." The fact that the US government has openly set "regime change in Cuba by the end of 2026" as a goal has raised tensions another notch.

Context: the numbers show a life in collapse

The impact on health and society is already visible in the figures. Infant mortality has risen to 9.9 per 1,000 live births, food production has fallen by 60%, and the availability of medicines is put at roughly 30% of normal levels. There are gaps between UN data and the Cuban government's figures, but they agree on the direction: conditions have deteriorated sharply. Electricity is the foundation of refrigeration, water supply and medical equipment alike, and prolonged blackouts translate directly into a health crisis.

The question: who bears the consequences of "pressure"?

Brazil's President Lula has openly criticized the oil blockade and called for humanitarian access to be secured. Among Latin American governments, concern over Washington's hardline stance is spreading across the political spectrum, left and right. The string of hardline moves toward Latin America that began with the detention of Maduro in January is being read, alongside the Panama Canal dispute, as an attempt to "change the status quo by force," and it is deepening the sense of US isolation at the Organization of American States (OAS) and the United Nations.

Meanwhile, Cuba's Foreign Minister Rodríguez has said that "negotiations between the US and Cuba are not advancing," and no diplomatic exit is in sight. When the goal of regime change and the deepening of a humanitarian crisis advance in parallel, the first to bear the consequences of the pressure is not the regime but the citizens. The people sitting in the darkness of the blackout are not the policymakers.

My perspective

Whether economic sanctions are right or wrong is a large question that goes beyond the scope of this article. What caught my attention in this news, though, is that a concrete number — "170 containers of humanitarian aid" — came from the UN. Debates over sanctions often turn into abstract exchanges, but the moment the contents of the stalled containers are identified as food and medicine, the discussion becomes one about the concrete survival of human beings.

Speaking from the position of someone who has followed health care in Latin America, a rise in infant mortality is one of the heaviest indicators of a society in crisis. Until that number turns back toward improvement, no one — from any political standpoint — should be able to claim that "the situation is under control." Keeping track of the numbers is, I believe, one of the few things those of us outside can do for this island.

Glossary

apagón = blackout. A nationwide blackout is called an apagón general. bloqueo = blockade; in Cuba it has long been the everyday word for the entire US sanctions regime. termoeléctrica = thermoelectric power plant, a word that appears constantly in coverage of Cuba's power crisis.

When an oil blockade stops even the containers carrying food aid, it is no longer trade policy — it is a question of humanity.
