Cuba’s power grid collapses again under the US oil cut-off

Cuba’s power grid collapsed on Friday, leaving millions of people without electricity³. The grid went down again as the Trump administration maintained its pressure on the government in Havana⁴. Cuba worked on Saturday to restore power¹.

Sources differ on the count. France 24 described it as the island’s seventh major blackout¹. CBS News called it at least the sixth time this year⁵. DW reported it as another nationwide blackout amid the US fuel blockade, and Al Jazeera as another major nationwide outage^2,7.

Whatever the count, the characterisation is consistent across outlets: a nationwide failure of the grid rather than a regional one^2,7. The Washington Examiner tied the collapse directly to the pressure the administration is applying to the island⁴.

Why it matters to investors

The policy mechanism is explicit. Trump signed an executive order that would impose tariffs on countries that sell or provide oil to Cuba, and the restrictions prevent the island from sourcing the fuel it needs⁵. The measure works through third countries rather than through Cuba directly, which is what gives it reach⁵.

The effect is now visible in the physical economy rather than in financial indicators. A national grid that fails repeatedly in a single year is the observable output of a fuel embargo enforced by tariff threat against suppliers^4,5. Washington has been applying that instrument more widely, which makes the Cuban case a working example of what the tool does^5,7.

What to watch

Not everything here is new. Blackouts have been a feature of life in Cuba for decades, even if the ban on oil sales to Havana has deepened the crisis⁶. The plant that was meant to free the island from its dependence on oil now stands as a symbol of that dependence instead⁶. CNN’s account is a reminder that the island’s power problems long predate the current measures⁶.

The questions from here are practical. How quickly the grid comes back after each collapse, and whether the intervals between failures shorten, will show whether the system is degrading or merely strained^1,3. Whether any supplier tests the tariff threat by shipping oil to Cuba will show how binding the executive order is in practice⁵. And whether the count of nationwide outages continues to rise through the rest of the year will be the plainest measure of the embargo’s effect^1,5.
