Cuba entered the 2025–26 academic year short 24,000 teachers, according to Education Minister Naima Trujillo — and that structural deficit has since been compounded by a fuel crisis severe enough to push universities off in-person instruction entirely since February 2026, UPI and The Atlantic report.

The proximate driver is a sustained U.S. effort to interdict oil shipments bound for Cuba. By late March 2026, Washington had blocked significant oil deliveries for nearly three months, the New York Times reported — a pressure campaign that has cascaded from power stations into every institution dependent on reliable electricity and fuel. Cuba produces only around 40% of its own oil, leaving it structurally exposed to external supply disruptions of exactly this kind, per Think Global Health.

A System Under Triage

When Havana moved to protect essential services in early February, it implemented a tiered response. Infant-care centers and primary schools kept their doors open for in-person classes. Secondary schools and universities shifted to hybrid learning models. The government announced structural measures to conclude the 2025–26 school year under these constraints, Reuters reported on February 8. That framework has since broken down further: by the time The Atlantic published its visual documentation in May, universities had abandoned in-person instruction altogether.

The sequencing matters. Hybrid models presuppose functioning internet infrastructure, device access, and enough residential power to run them — all of which are undermined by the same blackouts hitting homes, schools, and hospitals. The fuel crisis isn't afflicting the education system in isolation; it is degrading the entire material substrate the system runs on.

Protests and the Political Signal

In March, students at Havana University took to the streets over the energy crisis and its direct effects on their coursework, AP reported. Public protest remains rare in Cuba and carries real personal risk. That students chose to demonstrate anyway — and that the government has not, publicly, reversed course on the hybrid-learning policy — reflects the depth of the impasse on both sides.

The health-system parallel is instructive. Think Global Health documented in May that the fuel blockade has affected every domain of Cuba's health infrastructure: surgical capacity, cold-chain logistics for pharmaceuticals, hospital power backup. Education is experiencing the same resource-rationing logic, where institutions are ranked by political priority and fuel is allocated accordingly.

What the Blockade Is and Isn't

It is worth being precise about the mechanism. The U.S. has not imposed a formal naval blockade — the decades-old embargo already restricts most direct U.S.-Cuba commerce. What has escalated since late 2025 is secondary pressure: the U.S. targeting of third-party tankers and energy intermediaries supplying Cuba, using sanctions designations and port-access threats to deter non-American companies from completing deliveries. The effect at the pump and the power grid is the same as a supply cutoff, but the legal and diplomatic architecture is different, and matters for how third countries respond.

Cuba's pre-existing vulnerabilities make the pressure especially acute. The teacher shortage that predated the fuel crisis — 24,000 vacancies at the start of the school year — reflects years of emigration by working-age professionals, a trend that has accelerated as economic conditions deteriorated. The fuel crisis has now stacked an acute infrastructure shock on top of that chronic human-capital drain.

Looking at what this means for the near term: the 2025–26 academic year is effectively lost for secondary and university students in any meaningful in-person sense. The government's announced "structural measures" to conclude the year are an administrative acknowledgment of that reality, not a solution to it. Whether the next academic year opens under different conditions depends almost entirely on whether Cuba secures alternative fuel supply — from Venezuela, Russia, or other partners willing to absorb U.S. secondary-sanctions risk — or whether Washington eases pressure. Neither outcome appears imminent as of late June 2026.
