United States tightens Cuba sanctions, cutting private sector banking access and travel
New regulations from the US Treasury Department took effect on Wednesday, barring dollar U-turn transactions, freezing US bank accounts of Cuban private entrepreneurs, and restricting educational travel categories.
New financial and banking prohibitions
On Tuesday, 29 September 2026, the US Department of the Treasury's Office of Foreign Assets Control (OFAC) announced tightened sanctions against Cuba, with the updated regulations taking effect on Wednesday, 30 September. The new rules prohibit direct and indirect financial transactions involving sanctioned Cuban entities, focusing on those affiliated with the state security apparatus and the military-run business conglomerate GAESA. Under the revised framework, US financial institutions are barred from serving as intermediaries in transactions connected to listed Cuban firms.
The measures revoke authorization for "U-turn" transactions, a mechanism reintroduced by the Biden administration in 2024 that allowed US banks to process dollar-denominated fund transfers involving Cuba, provided both the originator and the recipient were located outside the United States and neither was a US national. Furthermore, the updated regulation revokes authorization for US banks to open and maintain accounts for independent Cuban private sector entrepreneurs. US institutions holding existing accounts for these micro-entrepreneurs must freeze the assets and report them to OFAC, with access restricted to individual licenses granted by the agency.
Restrictions on travel and exchange programmes
The OFAC regulatory package also scales back travel permissions introduced under the presidency of Barack Obama. General authorizations for US citizens traveling to Cuba for professional conferences and business meetings have been eliminated, placing these visits under individual licensing requirements. Group travel under the "people to people" cultural and educational exchange programme has similarly been restricted.
Under the new rules, educational travel is permitted only when organized under the sponsorship of a US organization and accompanied by an official representative of that organization. An exception remains in place for accredited US colleges and universities. The restrictions return cultural and professional visits to a framework of specific permits, curtailing bilateral exchanges between the two countries.

Trade flows and economic pressure
The regulatory action coincides with record levels of goods imports from the United States by Cuba's expanding private sector. Data from the US Census Bureau showed that Cuba imported $149 million in US goods in July 2026, marking the highest monthly import total recorded since 1992. Between January and July 2026, cumulative imports reached $674 million, matching nearly the entirety of the island's total US import volume for the full year 2025.
The expanding trade occurred alongside structural changes in Cuba, where the private sector accounted for 55% of total retail sales in 2024 according to official statistics, and where private enterprises received authorization to import fuel at the start of 2026. The new measures follow earlier sanctions moves in 2026, including a tariff mechanism established in late January on nations supplying oil to Cuba, which was subsequently lifted on 20 February 2026 before a Russian tanker delivered fuel to the island in March.
Reactions in Havana and commercial fallout
Cuban authorities stated that the measures directly target domestic economic reforms. In June 2026, Havana announced a reform package intended to develop market-oriented economic mechanisms across the island. Cuban Foreign Minister Bruno Rodríguez responded to the sanctions on the social media platform X.
These new blockade measures aim to hinder the ongoing economic transformation process. They openly attack both the public sector and the private sector, the very one that certain US officials claim they want to help develop.
Private sector analysts expressed concern over the practical consequences of severed US banking connections. Oniel Díaz, a business consultant for Cuba's private sector, noted that the measures eliminate banking links with the United States and warned that non-US banks may tighten their own compliance procedures as a result. Díaz stated that such compliance risks could disrupt payment channels for international purchases of food and fuel, on which private sector supply chains rely.
