Sanctions move from policy to mechanism as financial channels begin to close
The decision to cut Cuba off from its own credit card receipts took effect in a single line: Cuba will suspend Visa and Mastercard transactions starting June 6. The instruction did not come from a bank in Havana but from a chain reaction outside it—sanctions that pushed a foreign processor to step back, leaving the country unable to receive income from the sale of goods and services through internationally recognized cards.
That loss of payment rails followed a narrower move that now looks less contained. Washington announced fresh economic sanctions on Cuba’s president and some of his immediate family, alongside members of the Castro family, extending pressure beyond institutions to the people who sit at the centre of them. President Miguel Díaz-Canel and his family have been hit, as have relatives of Raúl Castro, including the son and a grandson of the former president, whose formal absence from office—he no longer holds an official position—has not removed him from decisions about the island’s future.
The measures do not stop at individuals. Sanctions now apply to the ministry of the revolutionary armed forces of Cuba, the Cuban Institute of Friendship with the Peoples, Amistur Cuba, and the committees for the defense of the revolution. They draw a perimeter around the state’s operating core, then extend outward: anyone providing services to these sanctioned actors is at risk of sanctions themselves. The instruction that follows is blunt. Foreign banks and other companies that provide services to these entities should freeze those activities.
Financial actors withdraw ahead of enforcement as risk becomes incalculable
The financial system tends to obey such signals before they are fully enforced. Cuba’s central bank describes the consequence in operational terms: a foreign partner that had previously processed credit card transactions for Cuba decided to limit operations after a U.S. executive order that vastly broadened sanctions on commerce with Cuba. The suspension of card payments is not an isolated measure but a symptom of institutions recalibrating exposure. Once a payments processor exits, others read the same risk.
That pattern has precedent. The United States has had an embargo on Cuba for decades, but the current phase is an escalation layered on top of it. President Donald Trump has drastically ramped up pressure on the island in recent months, pairing legal restrictions with rhetoric that has repeatedly signalled that the Cuban government could be next after Venezuela to fall to US pressure. The sanctions architecture now moves faster than the formal policy statements that justify it.
Energy is where that acceleration becomes visible. A de facto fuel blockade has deepened the island’s energy crisis and hit its already fragile economy. Fuel shortages do not stay confined to transport or electricity. They move through hospitals, water systems, and food distribution. The tightening of sanctions and the contraction of financial channels meet there, in the physical limits of what can be delivered and sustained.
Human impact emerges as the cumulative pressure shifts from systems to outcomes
The social data register the same pressure with less ambiguity. An analysis by Guillaume Long found that Cuba’s infant mortality rate soared by 148 percent from 2018 to 2025. The counterfactual is precise: approximately 1,800 deaths of infants would not have occurred had the rate remained stable. Alexander Main, a coauthor of the report, draws the line directly: the Trump policy of ‘maximum pressure’ on Cuba has killed a lot of babies, adding that it is highly likely that more babies are dying now, and at an even higher rate as the fuel blockade tightens.
Washington frames the campaign differently. The US is targeting the network that enables and funds Cuba’s subversive and radical operations, Marco Rubio says, because the country would no longer tolerate radical Marxist regimes exporting their “revolution”. The language casts the measures as surgical, directed at a network rather than a population. But the enforcement mechanism—the threat that any intermediary could be sanctioned—turns that network into a moving boundary. Each institution that withdraws redraws it.
The effect is cumulative. Tourism receipts that once flowed through card networks stall. A banking partner that once cleared transactions reduces its exposure. A ministry that once coordinated procurement finds suppliers unwilling to engage. None of these actions requires a formal directive once the risk is understood. They happen because the cost of staying becomes incalculable.
An economy that can produce but cannot be paid enters a different condition
Cuba’s economy, measured in aggregates, once appeared capable of absorbing shocks. Its GDP amounted to 107,352 million USD in 2020, a figure that suggests scale but not resilience. GDP records the sum of production; it does not capture the channels through which that production is monetised or paid for. When those channels close, output can persist without income.
That is the condition the current sanctions regime has exposed. The United States is no longer only restricting what Cuba can import or export; it is constraining how Cuba can be paid. The suspension of Visa and Mastercard transactions is not a technical inconvenience. It is the removal of a mechanism that converts activity into revenue, at the moment when other sources of hard currency are already under strain.
The Cuban state still holds ministries, committees, and a leadership structure that remains intact. It still produces goods and services. What it no longer reliably holds is access to the systems that turn those goods and services into usable foreign exchange. The sanctions are not dismantling the visible architecture of the state; they are stripping out the invisible infrastructure that lets it function as an economy.
When a country cannot process the payments for what it sells, the distinction between economic pressure and economic incapacity collapses. Cuba’s central bank has already named the consequence. The island can produce. It can sell. But it cannot get paid.
