Cuba's crisis is not just the story of a weakened regime. It is a modern laboratory of economic coercion, where energy, financial flows, international services and diplomatic alliances are used as instruments of pressure. For markets, the issue is not Cuba's modest economic weight on a global scale, but what this episode reveals: the re-emergence of power diplomacy exercised through economic channels, and the fragility of economies dependent on a limited number of strategic flows.

A Cuban economy in a critical phase

Cuba's economy is now facing its deepest crisis since the 1959 revolution. The island is absorbing several shocks at once: energy, financial, social and logistical.

The major rupture is energy. For years, Cuba relied on Venezuelan oil to keep its economic system running. That partnership relied on a "swap" mechanism: Caracas supplied crude, while Havana sent doctors, technical staff and administrative services. Venezuela delivered up to several tens of thousands of barrels of oil a day to the island.

The disappearance of that flow has triggered a brutal shock. Cuba's economy, already weakened by the pandemic and the collapse in tourism, now finds itself suddenly confronted with a structural energy shortage. Power cuts are multiplying and can last up to 48 hours. Public transport is paralyzed. Agriculture lacks fuel for machinery and irrigation systems. Aging thermal power plants are struggling to maintain even a minimum level of electricity output.

The macroeconomic effects are immediate. Output slows, logistics unravel and supply chains seize up. In a system already marked by rationing and shortages, the loss of an input as fundamental as energy acts to further stock the fire.

On top of that energy constraint comes a chronic shortage of hard currency. Tourism, the second-largest source of foreign-exchange revenue after the export of medical services, has suffered a lasting shock since the pandemic. Fuel-supply difficulties and logistical uncertainty are furhter aggravating the situation. Some airlines are beginning to suspend routes to the island due to the lack of available fuel.

Cuba's economy is thus caught in a vice: less energy means less activity, less activity means less hard currency, and less hard currency further reduces the ability to import the resources the country needs to function.

The US strategy: cutting off vital flows

US policy toward Cuba has historically rested on a simple principle: trigger an economic crisis deep enough to force political change.

Since the 1960s, the embargo has been the central pillar of that strategy. It seeks to limit Cuba's access to international trade, the global financial system and foreign investment. Over the decades, these sanctions have been tightened or loosened depending on the administration, but the underlying logic has remained constant.

The current sequence nonetheless marks a notable intensification. The US strategy now appears to be organized around three main pillars.

The first concerns energy. The United States is seeking to prevent any oil deliveries to Cuba by threatening sanctions against countries or companies that could supply the island. That pressure is being notably applied to regional partners such as Mexico.

The second pillar targets the regime's sources of hard currency. The export of medical services has, for decades, been a cornerstone of the Cuban economy. Thousands of doctors are deployed across Latin America, Africa or the Caribbean under cooperation programs. Washington views these missions as a political instrument and is pressuring partner governments to bring them to an end.

The third pillar rests on financial extraterritoriality. Foreign companies that trade with Cuba can be exposed to US sanctions or restrictions on access to the US market. This deterrent dimension helps further isolate the Cuban economy.

The objective is clear: to gradually reduce all external sources of financing for the regime.


A crisis that goes beyond Cuba

Tensions around Cuba are part of a broader regional strategy. Washington is seeking to reconfigure political and economic balances in Latin America, particularly in response to China's growing influence.

The summit dubbed "Shield of the Americas," held in Miami with several Latin American leaders, illustrates this desire to structure a political bloc aligned with US priorities. Officially devoted to the fight against cartels, the gathering also carries a broader geopolitical dimension.

On the one hand, this aims to strengthen the alignment of certain regional governments with Washington. On the other, the initiative is designed to limit the influence of external powers, notably China, over Latin America's strategic infrastructure.

In this context, Cuba appears as a strategic test. The island is a remnant of Latin American socialism and a political symbol in the Western Hemisphere. For Washington, securing a transformation of Cuba's regime would amount to a major geopolitical victory after recent developments in Venezuela.

Macroeconomic consequences: an economy under permanent constraint

In the near term, the main impact concerns energy and supply. Fuel shortages are causing a generalized disorganization of the economy. Transport, agriculture and public services are operating at just a crawl rate.

Inflation, fueled by the scarcity of goods, is weighing heavily on purchasing power as well. In a system where wages remain very low, the gap is widening between rationed channels and private channels where prices are far higher.

In the medium term, the hard-currency constraint is the main macroeconomic threat. The decline in tourism receipts and medical missions is limiting the country's ability to finance imports. Yet Cuba depends heavily on external sources for energy, medicines and many food products.

This mechanically increases country risk. Even in the absence of a developed financial market, risk perception translates into higher costs for commercial transactions, maritime insurance and international financing.

Over the longer term, the crisis could lead to a deterioration of productive and human capital. Infrastructure is aging, investment is dwindling and emigration is accelerating. Nearly half a million Cubans are said to have left the country in recent years.

Implications for markets

For global financial markets, Cuba remains just a marginal economy, however. Its GDP and foreign trade are too modest to trigger global shocks. Effects therefore show up mainly indirectly.

The energy sector is the first affected. Tensions in the region can increase logistical volatility around the Gulf of Mexico and Caribbean shipping routes. Alternative regional energy suppliers may benefit from these adjustments.

Maritime transport is a second transmission channel. Sanctions and financial restrictions complicate commercial operations linked to Cuba, raising insurance and compliance costs for certain operators.

Tourism represents a third vector of impact. The deterioration of economic and logistical conditions on the island is shifting demand towards other, more stable Caribbean destinations.

Finally, the rise in geopolitical risk in the region can support certain segments tied to security, critical infrastructure or energy sovereignty.

Three scenarios for the years ahead

The baseline scenario rests on a managed confrontation. The United States maintains strong economic pressure while keeping certain humanitarian or diplomatic channels open. Cuba continues to operate under a regime of prolonged scarcity, while informal talks help prevent a major escalation.

A second scenario would see a gradual transition emerge. Faced with the economic crisis, part of Cuba's elite could seek a compromise with Washington, involving a broader economic opening and limited political reforms.

The extreme scenario remains that of regional escalation. A tightening of the energy blockade or maritime incidents could trigger a broader Caribbean crisis. This hypothesis remains unlikely but cannot be entirely ruled out amid heightened global geopolitical tensions.

A real-world test of economic coercion

Cuba's crisis goes far beyond the question of the regime in Havana. It illustrates the shifting nature of power relations in the international system.

Dominance no longer necessarily comes through direct military occupation. It could be via the control of energy, financial and technological flows. In this new environment, the ability to control critical infrastructure and economic circuits becomes a central strategic lever.

For investors, the Cuban episode is a reminder of a reality often underestimated: geopolitics never truly disappears from the markets. It simply changes form. And when economic flows become instruments of power, even peripheral economies can become pressure points capable of reshaping regional balances.
