The U.S. State Department announced a new round of sanctions against Cuba on Thursday, September 3, 2026, targeting individuals and companies at the heart of the island's already-collapsing energy infrastructure — a move that drew sharp condemnation from Havana and signals Washington has no intention of easing pressure on the communist government [1].
Who and What Was Sanctioned
Among the newly designated targets are Fidel Ernesto Castro, a grandson of former President Raúl Castro, and Abapet, Cuba's Oil Industry Supply Import Company [1]. Abapet occupies a critical chokepoint in Cuba's energy supply chain: it is responsible for procuring the specialized equipment and spare parts that keep the island's aging power grid running — or, increasingly, failing to run [4].
The timing was pointed. The State Department's announcement came just hours after Cuban officials held a press conference in Havana to elaborate on sweeping economic reforms the government had approved in June, framing the juxtaposition as a deliberate signal from Washington [1].
A Grid Already on Its Knees
The sanctions land on an island where electricity has become a luxury. Daily blackouts now routinely exceed 24 hours, a crisis that accelerated after President Donald Trump threatened tariffs in late January against any country selling or supplying oil to Cuba, causing fuel reserves to dwindle and the aging grid to buckle further [1].
The human cost is visceral. Yaqueline Bernal, a 49-year-old Havana resident, told reporters Thursday that she had not had electricity since the previous Sunday — four days without power for a household that includes eight young grandchildren. "If we don't have power, we don't have water," she said. "You really don't know what's going to happen to you." [5]
Washington's Strategic Logic — and Its Limits
Brett Erickson, a sanctions expert and managing principal at Obsidian Risk Advisors, offered a blunt assessment of what the U.S. is attempting. "The goal in theory is to create so much civilian hardship and suffering that they have no option but to essentially rise up and topple their government," he said. "It is an attempt to cause a humanitarian crisis." [1]
Erickson characterized the Abapet designation as part of a deliberate escalation strategy: by cutting off the supply of maintenance components, Washington aims to push Cuba's critical machinery offline and compound the energy emergency. "The U.S. is trying to really tighten the screws as much as possible," he said [4].
He also noted that diplomacy appears to be off the table for now. Talks that had begun earlier in 2026 between Washington and Havana have since stalled, and sanctions have multiplied in the intervening months [1]. "The Trump administration seems to have no seriousness to accept any change from Cuba other than a toppling of regime," Erickson said, adding that Secretary of State Marco Rubio would not relent [4].
Yet Erickson cautioned that sanctions rarely achieve a clean result. Cuba's government, he predicted, would find workarounds — because it has no choice. "They'll get creative in how they try to procure these maintenance parts," he said, warning that black-market or third-party procurement would be far more expensive, feeding inflation and grinding down ordinary Cubans' purchasing power further [1]. He expects Washington to continue targeting progressively smaller state-owned companies, trying to push the broader economy "into a death spiral" [4].
Havana Fires Back
Cuban officials did not wait long to respond. Foreign Affairs Minister Bruno Rodríguez posted on X: "Collective punishment is a crime. So, too, is inflicting suffering on an entire population through measures coldly calculated to trigger a humanitarian crisis. Enough with the abuse. Put an end to the blockade once and for all and allow Cuba to live in peace." [5]
Cuba's ambassador to Mexico, Eugenio Martínez Enríquez, was more personal in his attack, calling Rubio "a liar without scruples" and writing, "We will not forget his crimes." [1]
Deputy Prime Minister Oscar Pérez-Oliva Fraga, speaking at the Havana press conference before the sanctions were announced, framed the broader crisis in stark terms: "This past year has been very complex, and we know why. The blockade is a genocide." [4]
Rubio's Framing
Secretary of State Rubio offered a starkly different narrative on X, asserting that those newly sanctioned "are part of the corrupt Castro financial and intelligence network." He argued that Cuba's leadership "preside over a failed state where ordinary Cubans go hungry while the Castro family and other insiders enrich themselves through sanctions evasion and other illicit schemes." He closed with a direct statement of intent: "Trump and I are unwavering in our commitment that Cuba will be free." [1]
The dueling public statements underscore that neither side sees room for near-term compromise. Washington frames its pressure campaign as targeting a corrupt elite; Havana frames it as collective punishment of a civilian population.
What to Watch
Several threads will determine how this escalation unfolds. First, whether third-party countries — particularly those in Latin America, Africa, or Asia that have historically traded with Cuba — comply with U.S. pressure or find ways to continue supplying Abapet's now-sanctioned operations. Second, whether Cuba's June economic reforms attract enough foreign investment to partially offset the energy and supply shortfalls, or whether the new sanctions undercut that effort before it can take hold. Third, and most immediately, how much further Cuba's power grid can deteriorate before it triggers a broader social or political rupture — the precise outcome Washington appears to be engineering, and that Havana is racing to prevent.
