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 issued a broad authorisation permitting PDVSA to sell crude oil to global markets, including US refiners, but included an explicit carve-out prohibiting deals involving Cuba, Russia, Iran, North Korea, and some Chinese entities.
The carve-out is the single policy decision that converts a general Venezuela sanctions reset into a Cuba-specific fuel siege.
A narrow 25 March licence opened a private-sector channel for Venezuelan crude while keeping the Cuban state blocked.
United StatesOn 25 March 2026 the US Treasury issued a narrow follow-up licence permitting Venezuelan oil sales to Cuban private-sector buyers only; GAESA and the Cuban state remain explicitly blocked.
The follow-up licence formalises a two-tier architecture in which private Cuban importers may trade where the state may not.
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 UNE (Unión Eléctrica Nacional) published its daily bulletin forecasting a 1,732 MW blackout at the 20:30 peak, against projected demand of 3,000 MW and available generation of 1,298 MW. CTE Ernesto Guevara unit 1, CTE Antonio Maceo units 3 and 5, and CTE Felton unit 2 were simultaneously out of service.
The daily grid bulletin is the primary-source reading of what the sanctions architecture actually costs in household kilowatt-hours.
A 29 January executive order declared a national emergency over Cuba and authorised tariffs against any country supplying its oil.
US President Donald Trump signed Executive Order 14380 on 29 January 2026, declaring a national emergency over Cuba and authorising secondary tariffs on any country supplying oil to Cuba, effectively extending the US sanctions extraterritorially.
EO 14380 is the instrument that projects US Cuba sanctions onto third-country shippers through secondary tariffs.
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 condemned Executive Order 14380 as 'an extreme form of unilateral economic coercion with extraterritorial effects,' warning that restricting Cuba's fuel imports risks constituting collective punishment of civilians.
It is the most senior multilateral legal challenge to the Cuba sanctions architecture since Trump's second-term Cuba policy took shape.
Cuba's Foreign Minister used X and Cubadebate on 14 April to accuse Washington of manufacturing confusion to sustain a fuel blockade.
On 14 April 2026 Cuban Foreign Minister Bruno Rodríguez Parrilla posted on X and Cubadebate accusing Washington of 'creating confusion' to maintain a fuel blockade, describing the sanctions as demonstrating an 'extraterritorial character' that 'intimidates, pressures and extorts' third-party firms trading with Cuba.
Havana is aligning its public line with the legal argument UN experts made in February, building an 'extraterritorial coercion' case for international forums.
The Anatoly Kolodkin delivered nine to ten days of Cuban demand on 31 March and Moscow announced a second vessel was loading.
FranceRussian tanker Anatoly Kolodkin docked at Havana on 31 March 2026 carrying roughly 730,000 barrels of crude oil — the equivalent of nine to ten days of Cuban demand. Russian Energy Minister Sergei Tsivilyov told an energy forum in Kazan that a second vessel was being loaded.
Russia's direct-to-Havana tanker route is the only reliable state-level fuel backstop surviving the 18 March carve-out.
The UN Resident Coordinator in Cuba called April humanitarian needs acute, counting 96,000 pending surgeries and a million people dependent on water trucking.
In April 2026 the UN Resident Coordinator in Cuba assessed that humanitarian needs 'remain quite acute and persistent,' with approximately 2 million people across 8 provinces targeted for assistance, 1 million dependent on water trucking, 96,000 pending surgeries including 11,000 for children, and a funding gap of $68 million against $26.2 million mobilised.
The April UN assessment is the first comprehensive multilateral quantification of the humanitarian cost of the combined sanctions and grid crisis.
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 StatesOn 13 March 2026 President Miguel Díaz-Canel announced 51 prisoners would be released in a spirit of goodwill as US-Cuba talks mediated by the Holy See got under way. On 3 April the Cuban government stated more than 2,000 prisoners had been freed.
The amnesty is Havana's diplomatic offering into The Vatican-brokered channel, and it sets the benchmark against which independent monitors are measuring compliance.
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) published its March 2026 report documenting 277 repressive actions including 53 detentions, and stated that no political prisoner was included in the announced amnesty; separately, Human Rights Watch reported on 8 April that releases from La Lima prison excluded government critics.
Independent monitoring contradicts the government's amnesty framing and sets the benchmark of 1,214 political prisoners against which any US concession would have to be weighed.
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 offices would begin accepting cash dollar remittances. Analysts at the Havana Consulting Group and CiberCuba attributed the move to a regime attempt to recapture remittance flows that have migrated to informal banquero networks, with formal remittances running 70 per cent below the 2019 baseline.
The move is a structural dollarisation concession by a government that has spent a decade restricting the dollar at retail.
Three Miami-area Republicans wrote to OFAC on 11 February demanding review of every active licence authorising US business with Cuban state entities.
On 11 February 2026 Florida Representatives Carlos Giménez (FL-26), Mario Díaz-Balart (FL-25), and María Elvira Salazar (FL-27) sent a joint letter to OFAC and the Bureau of Industry and Security demanding a comprehensive review and revocation of every active licence authorising US business with Cuban state-controlled entities.
The letter is the political upstream of the 25 March private-sector-only licence and the continuing pressure on Treasury's Cuba file.
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 and Juventud Rebelde cut to weekly Tuesday printing (8 pages); provincial newspapers ceased printing entirely, with the Cuban government citing EO 14380's fuel impact on printing supply chains.
The state's own flagship newspapers could not maintain daily print under EO 14380's fuel impact, a tacit admission of the supply-chain reach of US sanctions.
State Security held the director of independent outlet 14ymedio; the publication kept operating and she has continued to contribute.
On 28 January 2026 Yoani Sánchez, director of independent Cuban outlet 14ymedio, was detained by State Security in Havana. The publication continued to operate and she remains a contributor and podcast host.
The detention reiterates the cost of independent reporting on the island and frames the space in which outlets like 14ymedio still manage to publish.
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.
