Cuba suffered a second nationwide blackout in less than a week on Friday, according to Bloomberg Markets, underscoring how fuel shortages and grid weakness are feeding operational risk across the island’s energy system. For tanker markets, the outage keeps attention on Cuba’s need for steady fuel imports and on the fragility of supply chains serving power generation and refined product demand.
The report points to an aging grid, chronic fuel scarcity and US sanctions that have limited access to fuel and financing. That combination matters for shipping because sanctions exposure, payment risk and constrained procurement can complicate cargo flows, vessel availability and discharge planning into Cuban ports, even when domestic energy demand remains urgent.
