Tonight the Cuban grid is forecast to black out 1,732 MW of load at the 20:30 peak, more than half of projected demand. The fuel shortage driving that collapse is no longer incidental to US policy. It is the product of a two-tier sanctions architecture that eased Venezuelan oil sales to most of the world on 18 March while keeping the Cuban state explicitly carved out, a choice Havana now frames as a deliberate energy siege.
Washington eased Venezuela sanctions for the world and tightened them on Havana in the same stroke.
A broad US authorisation on 18 March let Venezuelan crude flow to global markets again, but named Cuba alongside Russia and Iran in the exclusions.
On 18 March 2026 the US Treasury let most of the world buy Venezuelan crude again, including American refiners, but carved Cuba out of the licence alongside Russia, Iran, and North Korea. Cuba's state oil importer, GAESA, is explicitly blocked, and gold and cryptocurrency settlement channels were closed to prevent workarounds.
The carve-out places Cuba in a structural category alongside strategic adversaries rather than among ordinary sanctions targets.
A narrow 25 March licence opened a private-sector channel for Venezuelan crude while keeping the Cuban state blocked.
United StatesOne week after blocking Cuba's government from Venezuelan oil, the US Treasury issued a follow-up licence on 25 March 2026 permitting Venezuelan crude sales to Cuban private businesses only. GAESA, which handles most fuel imports, stays blocked.
The move targets political pressure, not supply logistics. Cuba's private sector accounts for under 15 per cent of the economy and has no oil terminals for tanker-scale deliveries. A legal door opened; almost nobody on the Cuban side can walk through it.
Cuba's grid operator said it would fail to supply more than half of forecast demand at 20:30 on 15 April, with four thermal units simultaneously offline.
On 15 April 2026 Cuba's national grid operator UNE forecast it could meet only 43 per cent of evening peak demand, with available generation at 1,298 MW against projected need of 3,000 MW. Four major generating units sat offline simultaneously.
Cuba has built 54 solar parks, but they produce nothing after dark, and the four planned battery installations that could shift solar output into the evening have no confirmed in-service date.
A 29 January executive order declared a national emergency over Cuba and authorised tariffs against any country supplying its oil.
President Trump signed Executive Order 14380 on 29 January 2026, declaring a national emergency over Cuba and authorising secondary tariffs on any country that sells oil to the island. Mexican oil shipments that had backstopped Cuba's thermal fleet stopped within days once tariff exposure was flagged.
The order reaches further than a conventional embargo by threatening foreign shipping firms, insurers, and trading partners with no other American connection. Every fuel shortage in this briefing flows from that one signature.
Three UN Special Rapporteurs warned on 12 February that restricting Cuba's fuel imports risked qualifying as collective punishment of civilians.
On 12 February 2026 three UN Special Rapporteurs jointly condemned Executive Order 14380 as an extreme form of unilateral economic coercion, warning that restricting Cuba's fuel imports risks constituting collective punishment of civilians.
The rapporteurs flagged a risk rather than made a formal finding, a legal distinction that matters. The US says its sanctions are lawful; Cuba now holds the UN citation it needs for proceedings in multilateral forums where that language carries specific weight.
Cuba's Foreign Minister used X and Cubadebate on 14 April to accuse Washington of manufacturing confusion to sustain a fuel blockade.
Cuban Foreign Minister Bruno Rodríguez Parrilla posted on X and Cubadebate on 14 April 2026, accusing Washington of deliberately confusing other countries to maintain a fuel blockade and pressuring foreign firms into compliance with extraterritorial sanctions.
The language mirrors the phrasing three UN Special Rapporteurs used in February, which was no accident. Havana is building a legal record for UN and international forums where that framing carries weight, while leaving out the thermal fleet's own structural failings.
The Anatoly Kolodkin delivered nine to ten days of Cuban demand on 31 March and Moscow announced a second vessel was loading.
FranceThe Russian tanker Anatoly Kolodkin docked in Havana on 31 March 2026 carrying around 730,000 barrels of crude, enough to cover nine or ten days of Cuban demand. Russia's energy minister said Moscow had loaded a second vessel.
Moscow is the only state supplier defying the US secondary-tariff threat, treating the deliveries as a low-cost strategic signal that sustains Havana at minimal expense. Even on a reliable cadence, nine to ten days of crude buys survival rather than normalising supply.
The UN Resident Coordinator in Cuba called April humanitarian needs acute, counting 96,000 pending surgeries and a million people dependent on water trucking.
The UN assessed in April 2026 that roughly 2 million Cubans across 8 provinces need urgent help, with around 1 million dependent on water delivered by truck because fuel shortages have cut power to pumping stations. More than 96,000 people are waiting for surgery, including 11,000 children, and the UN has raised only $26.2 million of the $68 million needed.
Both US sanctions and decades of domestic underinvestment are producing the harm.
Cuba's president announced releases on 13 March as Holy See-mediated talks began with Washington; the government later claimed over 2,000 freed.
United StatesPresident Díaz-Canel announced on 13 March 2026 that Cuba would release 51 prisoners as a goodwill gesture while Vatican-mediated talks with the US got under way. By 3 April, the government said more than 2,000 had been freed.
Human rights monitors found almost none qualified as political detainees. Cuba made a large-sounding diplomatic gesture, Washington has offered nothing in return through 15 April, and the documented list of political prisoners barely moved.
OCDH documented 277 repressive actions in March and HRW reported on 8 April that La Lima releases excluded government critics.
United StatesOn 7 April 2026 the OCDH (Observatorio Cubano de Derechos Humanos) logged 277 repressive actions in March including 53 detentions, and confirmed no political prisoner appeared in the announced amnesty. Human Rights Watch reported the same finding a day later.
Independent monitors counted 1,214 political prisoners in March, with 28 new cases added in February alone. The Cuban government announced 2,000-plus freed; the count that human rights organisations track barely moved.
Cuba's state exchange network announced on 7 April it would accept dollar remittances, chasing flows that have migrated to the informal banquero network.
On 7 April 2026 CADECA, Cuba's state exchange network, announced its branches would begin accepting cash dollar remittances. Formal transfers have fallen 70 per cent from the 2019 baseline of roughly $3.7 billion, with more than 95 per cent of diaspora transfers now moving through informal couriers.
Accepting cash dollars at state branches reverses a dollarisation policy Cuba has held since 2004.
Three Miami-area Republicans wrote to OFAC on 11 February demanding review of every active licence authorising US business with Cuban state entities.
Three Republican members of Congress from South Florida wrote to the US Treasury sanctions office on 11 February 2026, demanding a review and cancellation of every licence allowing American business with Cuban state entities.
Treasury has not published a response, but the 25 March Venezuela licence, which blocked the state while permitting private Cuban buyers, already follows the logic their letter set out. Whether a broader revocation programme follows remains unclear.
Cuba's Communist Party paper and its youth edition went to Tuesday-only 8-page printing on 2 March, with provincial newspapers ending print entirely.
From 2 March 2026 Granma, the Communist Party's official newspaper since 1965, dropped to one eight-page edition a week and provincial newspapers stopped printing altogether. The Cuban government cited Executive Order 14380's impact on fuel and supply chains.
The admission stands out because Cuban state media rarely acknowledges operational failure in public. Provincial party structures outside Havana lost their primary print source at the same time as blackouts are making digital alternatives unreliable.
State Security held the director of independent outlet 14ymedio; the publication kept operating and she has continued to contribute.
State Security detained Yoani Sánchez, director of independent outlet 14ymedio, in Havana on 28 January 2026, the day before Trump signed his Cuba sanctions order. Authorities released her quickly and she continued working as a contributor and podcast host.
Cuba's pattern with high-profile independent journalists is brief, repeated arrests rather than long sentences: disruptive, intimidating, and harder to condemn internationally than a prison term. The outlet kept publishing through and after the detention.
The situation is escalating across three vectors simultaneously. On the grid: the 15 April UNE forecast of 1,732 MW shortfall follows a 1,860 MW actual on 14 April, and four major units are simultaneously offline with no confirmed return dates. On the diplomatic track: Havana's shift to public X-and-Cubadebate framing rather than quiet bilateral communication signals it has concluded the private channel is not productive, raising the temperature of the international legal argument. On the Moscow vector: Russia's open defiance of EO 14380 secondary tariffs is an unresolved enforcement test; if Washington does not act against the tanker owners and insurers, the secondary mechanism loses credibility; if it does, the confrontation escalates beyond Cuba into US-Russia trade relations.
