US Sanctions Environment Around Cuba Continues to Tighten

What changed

The United States introduced additional Cuba-related sanctions during September 2026. On 17 September, additional Cuban entities and individuals were targeted, including entities connected with the nickel sector and military-linked enterprises. Earlier September measures also affected additional Cuban financial, energy, mining and state-linked entities. Update 14 October 2026: on 7 October, U.S. Homeland Security Investigations announced the seizure or detention of 90 biodiesel shipments (about 615,000 gallons, valued at over USD 2.8 million) at Port Everglades and the Port of Houston, which U.S. authorities say were destined for ENETEC S.A., a sanctioned Cuban state entity. According to Reuters (12 October), Cuba’s Minister of Energy and Mines, Vicente de la O Levy, denied that ENETEC had any contract for these shipments and estimated that fuel reaching Cuba’s private sector through U.S. channels covers less than 3% of the country’s fuel needs. The seizures are a confirmed U.S. enforcement action; the alleged link to ENETEC is disputed by the Cuban government and has not been independently established.

What it means in practice

For international investors and businesses, sanctions compliance remains relevant when evaluating counterparties, banks, payment routes, suppliers, corporate ownership, import/export transactions, and projects involving US persons or US financial infrastructure. Fuel scarcity continues to affect electricity supply, transport, construction schedules and hospitality operations. Projects relying on imported fuel should verify the supplier, the final recipient and the payment route, and plan for backup energy.

CPS note

US sanctions and Cuban investment law are separate legal systems. A transaction that is permitted under Cuban law is not automatically permitted under US sanctions rules. International clients should therefore evaluate both where applicable.
