A nationwide power outage swept across Cuba on March 21, 2026, marking the second such event in less than a week, according to the country's energy ministry. The blackout affected the entire island, highlighting the fragility of Cuba’s energy grid amid ongoing fuel shortages. The crisis has been exacerbated by a sustained US oil blockade, which has severely limited the island’s access to vital petroleum supplies. As the grid continues to falter, the frequency and scale of outages signal a deepening systemic failure in Cuba’s energy infrastructure. The situation raises concerns about regional energy security and potential ripple effects on Latin American energy markets, particularly in the flow of oil and refined products. With no indication of immediate relief, the crisis underscores the vulnerability of critical infrastructure in politically strained environments.
