Key Points
—President Trump signed a new executive order on May 1 — International Workers’ Day — that extends Executive Order 14380 with secondary sanctions on foreign banks that process transactions for designated Cuban entities, threatening their dollar-system access.
—President Miguel Díaz-Canel called the order “moral poverty” and a “blockade reinforced”. The Trump administration has accumulated more than 240 Cuba-related sanctions and intercepted at least seven oil tankers since January.
—The order arrives as Cuba’s electricity deficit returned to over 1,500 MW after the Russian crude that briefly eased blackouts ran out, with the next Russian tanker — the sanctioned Sea Horse Universal — moving erratically across the Atlantic.
A new executive order signed on Workers Day extends US pressure beyond the island and onto every foreign bank still doing business with the Cuban state. Havana called it moral poverty. Washington called it the end of looking the other way.
A new Trump Cuba sanctions escalation signed on Friday May 1 — the same day Raúl Castro and President Miguel Díaz-Canel led the Workers’ Day rally at the José Martí Anti-Imperialist Tribune across from the US embassy in Havana — extends Executive Order 14380 with the most consequential change in US-Cuba sanctions architecture in over a decade. The Rio Times, the Latin American financial news outlet, reports that the order, grounded in the International Emergency Economic Powers Act (IEEPA), authorises secondary sanctions on foreign financial institutions and corporates that process significant transactions for sanctioned Cuban entities, with Treasury empowered to cut their access to US correspondent accounts or block their US assets directly.
The order also blocks all property and interests in property of designated persons in the United States, extends entry bans to adult family members of designated persons, and explicitly waives prior notification — citing the speed of digital asset transfers as justification. Designations cover Cuba’s energy, defence, mining, financial services, and security sectors, plus anyone “materially supporting” the regime, complicit in human-rights abuses, or involved in corruption including embezzlement of public assets and expropriation.
Why This Trump Cuba Sanctions Escalation Is Structurally Different
The earlier 14380 framework, signed January 29, declared a national emergency and imposed secondary tariffs on countries supplying oil to Cuba. The May 1 order does something different: it reaches into the global banking system. Any bank that facilitates a “significant transaction” for a sanctioned Cuban entity now faces the choice between continuing that relationship or losing dollar-clearing rights — a binary most international banks resolve by walking away from the Cuban exposure.
European Union institutions have repeatedly described US secondary sanctions as a violation of international law on extraterritoriality grounds, and the UN General Assembly has voted against the broader US embargo for 32 consecutive years. The legal critique does not change the operational consequence. Spanish hospitality groups, European energy traders and Latin American banks with Cuban exposure now face the same compliance review.
The Salazar and Rubio Framing
Florida Republican María Elvira Salazar, the most influential Cuban-American voice in the House, captured the administration’s framing in a single line: “The era of looking the other way is over.” She described the Cuban regime’s alignment with Iran and Hezbollah as “a national security reality just 90 miles from our coast” and credited Trump‘s maximum-pressure approach by name. Representatives Carlos Giménez and Mario Díaz-Balart and Senator Rick Scott echoed the same message within hours.
Secretary of State Marco Rubio supplied the security-policy spine. In a Fox News interview taped at the State Department on April 27, he said the United States “will not allow any foreign military, intelligence, or security apparatus to operate with impunity 90 miles off the US coast under President Trump”, citing Russian intelligence presence and at least four — and by some assessments twelve — Chinese signals-intelligence facilities identified by the Center for Strategic and International Studies, including El Salao in Santiago de Cuba, 70 miles from the Guantánamo naval base.
Havana’s Response
Díaz-Canel responded on X within hours: the order shows the United States’ “moral poverty and contempt for the sensibility and common sense of Americans and the entire international community”. Foreign Minister Bruno Rodríguez Parrilla called the measures “repudiable, illegal, abusive and ridiculous”, adding the now-familiar formula that “Patria, Revolution and Socialism are defended with ideas and with arms — they will not intimidate us”.
The political theatre carried real cost. Hours after the EO was signed, Trump told a private West Palm Beach dinner he intended to “take Cuba almost immediately” once the Iran file is closed and floated stationing the USS Abraham Lincoln carrier off the Cuban coast — language Díaz-Canel described as a military threat of “dangerous and unprecedented scope”. The US Senate had, three days earlier, rejected by 51 to 47 a Democratic war-powers resolution that would have constrained presidential authority over military action against Cuba.
The Energy Crisis Backdrop
The sanctions escalation lands on a power grid in collapse. Cuba’s electricity deficit returned to over 1,500 MW by April 30 after the 730,000 barrels delivered by Russian tanker Anatoly Kolodkin on March 31 ran out, with provincial outages of 24 hours daily and Saturday’s projected deficit reaching 1,415 MW against demand near 3,100 MW. Nine of 16 thermoelectric units were offline, and 40 percent of generation capacity from distributed diesel motors is paralysed for lack of imported fuel.
The next Russian tanker — the EU- and US-sanctioned Sea Horse Universal — has been moving erratically and at low speed across the North Atlantic, mirroring the route the Kolodkin used to evade detection. Bloomberg and Kpler tracking data point to a Cuba-bound delivery that may not arrive before late May, while Energy Minister Vicente de la O has said Cuba would need eight Kolodkin-equivalent shipments per month to meet demand. The Trump administration has intercepted at least seven Cuba-bound tankers since January.
What It Means for the Region
For Mexican banks with historical Cuban exposure, for Spanish hospitality and energy operators with island assets, and for any Latin American counterparty processing dollar payments touching the Cuban state apparatus, the May 1 order rewrites the compliance calculation overnight. The Economist Intelligence Unit projects Cuban GDP to contract 7.2 percent in 2026 on top of an already 23 percent cumulative decline since 2019, and CEPAL forecasts a 6.5 percent contraction. Either reading puts the island in its deepest economic distress since the Special Period of the 1990s.
For LATAM allocators, the operational sequence is what matters. The Trump Cuba sanctions escalation now sits alongside the Venezuela transition and the Hormuz escort operation as part of a single energy-and-pressure architecture being built across three theatres — and the same Republican Senate majority that has not constrained any of them is unlikely to constrain the next move on Cuba either.
Workers Day in Havana ended with the rally, the rebuttal, and the next blackout. The May 1 executive order ensures the financial space around the regime gets smaller every week, and the political destination remains the one Washington has refused to pretend is anything other than regime change.
