How the U.S. is leveraging tariff threats, naval actions, and secondary sanctions to cut off Cuba's last fuel lifelines—triggering nationwide blackouts, mass protests, and warnings of imminent humanitarian collapse
How the U.S. is leveraging tariff threats, naval actions, and secondary sanctions to cut off Cuba's last fuel lifelines—triggering nationwide blackouts, mass protests, and warnings of imminent humanitarian collapse
The United States has imposed economic pressure on Cuba for 64 years. Now, for the first time, Washington is threatening to punish any country that sells oil to the island. President Trump's January 29 executive order creates a tariff mechanism targeting third countries that supply Cuban fuel—a significant escalation that goes beyond traditional bilateral sanctions to coerce allies and trading partners into joining an energy blockade. The strategy has proven devastatingly effective: Cuba's national power grid collapsed entirely on March 17, 2026, leaving approximately 10 million people without electricity and triggering ten consecutive days of street protests—the most visible civil unrest in years. The blackout deepened shortages of food, medicine, and water, and included the vandalization of a Cuban Communist Party provincial office in Morón, signaling fractures in state control.
The United States has imposed economic pressure on Cuba for 64 years. Now, for the first time, Washington is threatening to punish any country that sells oil to the island.

The blackout deepened shortages of food, medicine, and water, and included the vandalization of a Cuban Communist Party provincial office in Morón, signaling fractures in state control.
The timing was deliberate. Since U.S. forces captured Venezuelan President Nicolás Maduro on January 3, Cuba has lost access to Venezuelan crude, which provided a third of its oil imports. Mexico, Cuba's remaining major supplier, paused shipments the day before Trump signed the order and confirmed $496 million in 2025 supplies via Pemex. With its antiquated power grid already failing—five nationwide blackouts in the past year—and no new suppliers stepping in despite Chinese support pledges, Cuba now faces what the UN warned in February could become a humanitarian 'collapse.' The CIA assessed the economy is 'on the brink' in January; the March 17 grid failure suggests that brink has been crossed. Recent U.S. aid of $6 million targets hurricane relief, but analysts describe the situation as beyond humanitarian mitigation—the question now is whether the government can maintain control as basic services vanish.

Scenarios
1
Cuba's Economy Collapses, Mass Exodus Accelerates
Discussed by: CIA assessment (January 2026), Foreign Affairs, Pavel Vidal (former Cuban central bank economist)
Without reliable fuel supplies, Cuba's already fragile infrastructure fails entirely. Rolling blackouts become permanent in most provinces, food distribution breaks down, and hospitals lose power. The exodus of Cubans—already exceeding one million since 2020—accelerates dramatically. The government maintains control through rationing and security services but cannot provide basic services. This scenario does not necessarily lead to regime change; analysts note authoritarian governments have survived similar crises (North Korea in the 1990s).
Discussed by: Latin American policy analysts, Mexican political commentators
President Sheinbaum, facing domestic pressure from her party's left wing, resumes oil shipments to Cuba despite U.S. tariff threats. The Trump administration imposes duties on Mexican imports. Mexico challenges the tariffs at the World Trade Organization and through USMCA dispute mechanisms. This triggers a broader trade confrontation that overshadows the Cuba question. Sheinbaum frames resistance as defending Mexican sovereignty against U.S. 'blackmail.'
3
Supreme Court Strikes Down IEEPA Tariff Authority
Discussed by: Brennan Center for Justice, Bloomberg legal analysts, Tax Policy Center
The Supreme Court rules in <em>Learning Resources v. Trump</em> that the International Emergency Economic Powers Act does not authorize tariffs, invalidating the legal mechanism underlying the Cuba executive order. The administration pivots to other statutory authorities or requests congressional action, but enforcement of the Cuba oil tariffs is delayed or abandoned. Lower courts have already ruled against IEEPA tariffs.
4
Cuba Negotiates Concessions, U.S. Eases Pressure
Discussed by: Trump administration officials (implied in statements about 'making a deal')
Facing economic catastrophe, Cuba's government signals willingness to negotiate. Potential concessions could include releasing political prisoners, reducing ties with Russia and China, or permitting international monitoring. The Trump administration, seeking a foreign policy win, agrees to permit limited oil imports in exchange. This scenario requires both sides to accept terms the other has historically rejected.
5
China Steps In as New Oil Supplier, Defies U.S. Tariffs
Discussed by: Chinese Foreign Ministry statements (January 30, 2026), Latin America foreign policy analysts
After publicly pledging support for Cuba's sovereignty, China begins shipping oil to the island through state-owned companies or intermediaries, calculating that the economic and diplomatic costs of U.S. tariffs are worth the geopolitical gains. This transforms the Cuba crisis into a direct U.S.-China confrontation, with Beijing testing Washington's willingness to impose punitive tariffs on its largest trading partner. Trump faces a choice: back down and appear weak, or trigger a major trade war over Cuba.
6
Regime Instability Accelerates; Military Fractures or Coup Attempt
Discussed by: CIA assessments (March 2026), Latin American security analysts, former Cuban military officials
The March 17 grid collapse and subsequent mass protests represent the first visible crack in state control since the Special Period. If blackouts persist and protests spread to major cities like Havana, military units responsible for internal security may face impossible choices: fire on civilians and risk defections, or stand down and signal regime weakness. Historical precedent (East Germany 1989, Soviet Union 1991) shows authoritarian militaries sometimes fracture when ordered to suppress large-scale civilian unrest. A coup attempt by hardliners seeking to restore order through even harsher measures, or by reformers seeking negotiated transition, becomes plausible if the current government appears unable to restore electricity or basic services within weeks.
Historical Context
Cuba's Special Period (1991-2000)
1991-2000
What Happened
When the Soviet Union collapsed, Cuba lost $4.3 billion in annual subsidies and 85% of its trade partners overnight. Oil imports fell to 10% of pre-1990 levels. GDP dropped 35% by 1993. More than 50,000 Cubans developed vitamin deficiency-related blindness. An estimated 35,000 people attempted to flee on rafts.
Outcome
Short Term
The government eliminated 15 ministries, cut defense spending 86%, and legalized U.S. dollar circulation. Cubans lost an average of 12 pounds.
Long Term
Cuba survived by finding a new patron: Hugo Chávez's Venezuela began providing subsidized oil in the early 2000s, enabling economic recovery.
Why It's Relevant Today
Today's crisis mirrors the Special Period—sudden loss of a primary energy supplier combined with ongoing U.S. sanctions. The difference: Cuba may not find another patron willing to subsidize its economy.
U.S. Secondary Sanctions on Iranian Oil (2018-2020)
November 2018 - January 2021
What Happened
After withdrawing from the Iran nuclear deal, the Trump administration threatened sanctions on any country importing Iranian oil. Eight countries initially received waivers; in 2019, all waivers were revoked. Secondary sanctions on foreign businesses rose from 2 in 2018 to 104 by 2021.
Outcome
Short Term
Iran's oil exports fell by more than 50%. The Iranian rial collapsed. European allies' attempts to create alternative payment mechanisms (INSTEX) failed.
Long Term
Iran developed a 'shadow fleet' of tankers to evade sanctions, selling oil to China at discounted prices. The sanctions inflicted economic pain but did not change Iranian policy.
Why It's Relevant Today
The Cuba executive order uses the same template: secondary sanctions threatening third countries. The Iran experience shows such pressure can reduce but not eliminate oil flows, especially if major buyers (China) refuse to comply.
U.S. Oil Embargo on Japan (1941)
August 1941
What Happened
After Japan expanded into French Indochina, the U.S. froze Japanese assets and cut off oil exports—Japan's military imported 80% of its oil from America. Britain and the Dutch East Indies followed with their own embargoes.
Outcome
Short Term
Japan calculated it had 18 months of oil reserves. Rather than accept strategic suffocation, military leaders chose war.
Long Term
Japan attacked Pearl Harbor four months later. The embargo achieved its goal of confronting Japanese expansion—but triggered a conflict the U.S. had hoped to avoid.
Why It's Relevant Today
Energy embargoes can produce unintended escalation. Cuba lacks Japan's military capacity, but the historical lesson is that cornered nations sometimes choose desperate options rather than capitulation.
