State and Treasury officially announced sanctions on five entities and one individual
US hits Cuba with five entity sanctions
Washington blacklists a Castro family member, state trade bank, and key energy firms as island blackouts worsen.
In a nutshell
A targeted US sanctions push launched under Executive Order 14404 in May 2026 escalated through summer designations of military and energy targets, culminating on September 3 with blacklists against Raúl Castro's grandson, Cuba's foreign trade bank, and state fuel importer Comercial Cupet. By severing core banking rails and petroleum logistics during an existing power crisis, the measures freeze US assets and push Havana toward non-Western trade channels as fuel and currency shortages worsen.
Highlights
- Executive Order 14404 took effect on May 1, 2026, establishing broad legal authority to penalize Cuban state commerce.
- US agencies sanctioned energy intermediaries and military conglomerates on July 23, 2026.
- The State Department blacklisted nine entities and three individuals tied to regime activities on August 20, 2026.
- Banco Exterior de Cuba, fuel importer Comercial Cupet, and Fidel Ernesto Castro Calis were designated on September 3, 2026.
- The Treasury issued General License 4A alongside the September 3 designations to exempt diplomatic missions.
From the Editor’s Diary
Sanctioning core correspondent banks and fuel conduits leaves targeted states little alternative except rerouting critical payments through non-Western bilateral channels, accelerating the fragmentation of international commerce.

In short
TL;DR: The US froze the assets of Cuba's foreign trade bank, oil import network, and Raúl Castro's grandson, intensifying economic curbs during severe island-wide power cuts.
Q: What did the latest US sanctions target and what do they cut off?
- Five state-linked entities and one Castro family member were added to US blacklists.
How it unfolded
Trump Signs Broad Sanctions Order Against Cuban State
The current wave of economic pressure began on May 1, 2026, when President Donald Trump signed Executive Order 14404. The directive gave federal agencies broad legal power to blacklist individuals, commercial sectors, and businesses judged to be financing or supporting the Cuban government and its security services.
Washington Escalates Pressure on Energy and Military Firms
With broad authority established, the administration carried out sequential sanctions rounds through July and August 2026 to constrict Cuba's access to foreign currency. Federal authorities targeted military-run holding firms, political entities, and fuel intermediaries on July 23, before blacklisting nine additional entities and three individuals on August 20. Each round narrowed Havana's options for settling cross-border accounts, setting the stage for direct action against primary financial channels.
US Penalizes Castro Grandson, Trade Bank, and Mines
Washington completed its shift from peripheral intermediaries to core state channels on September 3, 2026, blacklisting Fidel Ernesto Castro Calis, Banco Exterior de Cuba, and four resource ventures. The Treasury published formal asset freezes against oil company Comercial Cupet while issuing General License 4A, an exemption maintaining basic operational transactions for foreign diplomatic missions. The designations barred US persons from conducting business with the targets, locking Cuba's foreign trade bank and mineral extractors out of standard dollar-clearing rails.
Where things stand
The sanctions are active, fully freezing the US assets of the designated entities and barring any transactions involving US persons. Banco Exterior de Cuba and Comercial Cupet are cut off from mainstream Western correspondent banking networks and US dollar clearance.
Attention now turns to whether Cuba will attempt alternative bilateral trade settlement mechanisms with partners such as China and Russia, and whether the disruption to fuel imports will deepen electrical grid failures across the island.
