Cuba experienced a complete blackout across the entire island on March 21, 2026, according to the country’s energy ministry. This marks the second nationwide power failure in under seven days, highlighting the deteriorating state of the nation’s energy grid. The outages are attributed to persistent fuel shortages stemming from a sustained US oil blockade, which has severely restricted Cuba’s ability to generate electricity. The repeated blackouts reflect systemic vulnerabilities in Cuba’s power infrastructure and its reliance on imported energy supplies. As the crisis continues, concerns are mounting about the broader implications for regional energy stability, particularly in Latin America and the Caribbean, where logistical and supply chain disruptions could follow. The situation adds to global market anxieties, with energy-related indicators such as CL=F, NG=F, and ^VIX reflecting heightened uncertainty.
