Cuba Under Pressure: Crisis, Sanctions, and Geopolitics in Trump’s Second Term

While global attention lately has mainly been focused on flashpoints such as the Strait of Hormuz, a profound and rapidly escalating crisis has been unfolding much closer to the United States: Cuba. Since the beginning of Donald Trump’s second presidency in 2025, the island has entered one of the most severe periods of economic, political, and humanitarian strain since the collapse of the Soviet Union. This crisis is not the result of a single factor but rather the convergence of intensified U.S. pressure, energy shortages, geopolitical realignment, and long-standing structural weaknesses within Cuba itself.

A Return to “Maximum Pressure”

From the outset of his second term, Trump moved decisively to reverse the partial thaw in U.S.–Cuba relations that had occurred under previous administrations. Cuba was quickly redesignated as a state sponsor of terrorism, and sanctions were expanded to include tighter restrictions on trade, travel, and financial flows.

More significantly, in early 2026 the administration escalated its strategy into what analysts describe as a renewed “maximum pressure” campaign. This included a dramatic step: restricting oil shipments to Cuba and threatening tariffs on any country that continued supplying fuel to the island. Because Cuba depends heavily on imported oil -historically from Venezuela and, to a lesser extent, Mexico- this policy had immediate and devastating consequences. Fuel shortages intensified, electricity generation collapsed, and the country experienced multiple nationwide blackouts.

The policy reflects a broader geopolitical goal. The Trump administration has framed Cuba not only as an authoritarian state but as a node in a network of adversarial alliances involving Russia, China, and other actors.

The Energy Crisis: A System on the Brink

Energy has become the central axis of Cuba’s current crisis. The cutoff of Venezuelan oil -following U.S. actions against the Maduro government in January 2026- removed Havana’s primary energy lifeline. At the same time, U.S. pressure led other suppliers to step back. Mexico temporarily halted oil shipments, and Washington warned it would penalize any country continuing to provide fuel.

The result has been what many observers describe as a near-collapse of the national grid. Blackouts have become routine, affecting hospitals, transportation, and food supply chains. For this reason, Russia has stepped in to partially fill the gap, sending oil shipments and pledging continued support, though these deliveries are insufficient to stabilize the system long-term.

Meanwhile, some analysts argue that Cuba could theoretically break free from its dependence on imported fossil fuels-and by extension from the pressure created by U.S. restrictions- through a large-scale shift to renewable energy.Such a transition, though, would require billions of dollars in investment. Indeed, with an investment of around $8 billion, Cuba could generate more than 90% of its electricity domestically using renewable sources such as solar, wind, hydroelectric, and bioenergy. However, such funding is currently out of reach under sanctions.

Economic Collapse and Social Strain

The energy crisis has amplified an already fragile economic situation. Years of sanctions, declining tourism, and structural inefficiencies had weakened the Cuban economy even before 2025. GDP had already contracted significantly, and shortages of food, medicine, and basic goods were widespread.

Under the renewed U.S. pressure, these problems have deepened. Fuel shortages have disrupted agriculture and transportation, contributing to rising food insecurity. Healthcare -long a point of national pride- has been strained by lack of supplies and electricity. There are also signs of growing social unrest. Protests linked to shortages and blackouts have occurred intermittently since 2024, reflecting rising public frustration.

At the same time, migration pressures are increasing. With legal pathways tightening -such as Nicaragua ending visa-free entry for Cubans- escape routes have narrowed, raising concerns about a potential migration crisis affecting the United States and the broader region.

 Diplomatic Isolation and Limited Openings

That is because alongside economic pressure, the Trump administration has pursued a strategy of diplomatic isolation. It has pressured countries to cut ties with Cuban programs, particularly the export of medical personnel, which is a key source of revenue for Havana. Several countries, including Honduras and Guatemala, have scaled back or ended these programs under U.S. pressure.

Yet paradoxically, even as tensions have escalated, recent weeks have seen tentative diplomatic engagement. In April 2026, U.S. and Cuban officials held high-level talks in Havana, the first such meeting in years. These discussions were described as respectful but revealed deep divisions. Cuba has demanded an end to the so-called “energy blockade”, while the United States has insisted on political reforms, including the release of political prisoners.

The talks suggest that both sides recognize the risks of further escalation, even as they remain far apart on core issues.

The Specter of Regime Change

Perhaps the most controversial aspect of U.S. policy has been the explicit suggestion that regime change in Cuba is an objective. Trump has repeatedly indicated that the Cuban government must “make a deal” or face serious consequences.

In more provocative statements, he has even suggested that the United States could “do something with Cuba very soon”, fueling speculation about potential intervention. This rhetoric, combined with actions such as the oil blockade and military moves in Venezuela, has heightened fears in Havana that Cuba could be the next target of U.S. intervention.

For this reason, Cuban officials have responded by seeking diplomatic outreach -including reportedly attempting backchannel communication with the Trump administration- to avoid escalation.

Geopolitics: Cuba in a New Cold War?

Cuba’s crisis cannot be understood in isolation; it is deeply embedded in a broader geopolitical contest.

Russia’s willingness to supply oil and China’s potential support highlight how the island remains strategically significant.  For Washington, limiting the influence of these powers in the Western Hemisphere is a central objective.

This dynamic has echoes of Cold War politics, though the context is different. Instead of ideological confrontation alone, today’s struggle involves energy security, economic leverage, and regional stability.

Humanitarian Concerns and International Criticism

The humanitarian implications of the crisis have drawn international concern. Critics argue that the U.S. energy blockade risks pushing Cuba toward a full-scale humanitarian disaster, particularly given its impact on electricity, healthcare, and food systems.

Even within the United States, there is debate. Some lawmakers have called for easing tensions and prioritizing humanitarian considerations, warning that current policies could trigger instability and mass migration.

A Crisis at a Crossroads

Cuba today stands at a critical juncture. The combination of external pressure and internal fragility has created a situation that is both volatile and unpredictable.

On one path lies further escalation: deeper economic collapse, increased social unrest, and potentially even confrontation between the United States and Cuba or its allies.

On another lies negotiation: a difficult and uncertain process that could involve economic reforms in Cuba and a partial easing of sanctions by Washington.

For now, the trajectory remains unclear. What is certain, however, is that Cuba’s crisis is no longer a peripheral issue. It is a central front in the evolving geopolitical landscape of the Americas, and one whose consequences could extend far beyond the island itself.
