What Are OFAC Sanctions on Cuba? A Plain-English Guide to the Embargo
Understand how U.S. Treasury’s OFAC rules—especially the CACR (31 CFR 515)—shape trade, travel, payments, and investment involving Cuba, plus the key lists, licenses, and compliance steps.
The plain-English answer: what “OFAC sanctions on Cuba” means
In practice, “OFAC sanctions on Cuba” means the U.S. government—through the Treasury Department’s Office of Foreign Assets Control (OFAC)—sets detailed rules that restrict most U.S. economic dealings with Cuba. These rules cover what U.S. persons can buy, sell, finance, insure, ship, invest in, or provide services for when Cuba is involved.
The core regulation is the Cuban Assets Control Regulations (CACR), codified at 31 CFR 515. The CACR is what people usually mean when they say “the U.S. embargo on Cuba,” though the embargo also includes statutes passed by Congress and other agencies’ rules.
Key idea: the CACR is not a single blanket prohibition. It’s a default prohibition plus a set of exceptions. Those exceptions come mainly through “general licenses” (pre-authorized categories of activity) and “specific licenses” (case-by-case approvals).

Who is covered, and what kinds of activities are restricted
OFAC rules generally apply to U.S. persons: U.S. citizens and permanent residents (green-card holders) wherever they are, entities organized under U.S. law (and their foreign branches), and anyone physically in the United States. Non-U.S. companies can also face “secondary” exposure in limited ways (for example, if they cause U.S. persons to violate rules, rely on U.S. financial infrastructure, or trigger other U.S. legal provisions).
Under the CACR, common restricted areas include:
- Payments and banking: many Cuba-related transactions are prohibited unless licensed. U.S. banks and payment processors are typically cautious even when activity is arguably authorized, because compliance risk is high.
- Trade and services: exports/imports and service provision can be restricted by OFAC and also by the U.S. Commerce Department’s Export Administration Regulations (EAR). OFAC is only one piece of the puzzle.
- Travel spending: pure “tourist travel” by U.S. persons is not authorized. Travel can be permitted under specific categories and conditions, but the rules focus on what activities and expenditures are allowed.
- Investment and joint ventures: many structures that look like “normal” emerging-market investing become difficult because Cuban counterparties may be state-linked, restricted, or require prohibited financing channels.
Two Cuba-specific lists matter in day-to-day due diligence. The Cuba Restricted List (published by the U.S. State Department) identifies entities and subentities with which direct financial transactions by U.S. persons are prohibited. The State Department also maintains the Cuba Prohibited Accommodations List, relevant for travel compliance. These lists are separate from OFAC’s standard sanctions lists, but they interact with OFAC compliance programs because they affect what transactions are permitted.
As an illustration of how list-based compliance works, the State Department’s Cuba Restricted List has, at times, contained hundreds of entries (for example, 247 entities in one recent published update), including state-affiliated tourism and retail groups. For sector-level implications, see /sectors/sanctions and /sectors/tourism.
How the embargo “works” in legal and operational terms
Think of Cuba sanctions as a system with four moving parts:
- Statutes: laws passed by Congress that set boundaries and limit executive flexibility.
- Regulations: OFAC’s CACR (31 CFR 515) translating policy into compliance rules.
- Licensing: general licenses (GLs) and specific licenses creating permitted channels.
- Enforcement and risk controls: penalties, audits, and “de-risking” by banks, shippers, insurers, and platforms.
A general license (GL) is a standing authorization written into OFAC rules. If your activity fits the GL’s conditions, you do not apply to OFAC—you comply with the terms and keep records. A specific license is a written permission you request from OFAC for an activity not already covered by a GL.
For readers trying to decode the CACR quickly, it helps to separate: (a) what is prohibited by default, (b) what is authorized under a GL, and (c) what is theoretically licensable but operationally hard because banks or counterparties won’t touch it.
Two practical tools can shorten that learning curve: the /tools/ofac-cuba-general-licenses reference and the /tools/ofac-cuba-sanctions-checker for initial screening and scoping.
Travel: “not tourism,” but categories with compliance obligations
U.S. persons often encounter Cuba sanctions first through travel rules. OFAC authorizations generally focus on purpose and activities (for example, certain educational, journalistic, professional research, humanitarian, or family-related travel). The compliance burden is not only whether you can go, but whether your spending and itinerary fit an authorized category and avoid prohibited accommodations or transactions.
Because travel rules overlap with documentation and entry requirements, it’s useful to cross-check logistics separately at /tools/cuba-visa-requirements.
Finance: why “authorized” does not always mean “bankable”
Even when a transaction is licensed, the payment path may fail due to intermediary bank controls, correspondent banking restrictions, or internal compliance policies. This is a common point of confusion: the law might permit an activity, but financial institutions may still refuse to process it because they cannot easily verify end-users, counterparties, or ultimate beneficial ownership.
Cuban counterparties: state conglomerates, the private sector, and currency mechanics
Sanctions compliance is not just U.S.-side law; it’s also about how Cuba’s economy is organized. Many large Cuban counterparties sit within state structures or military-linked business groups. One frequently cited group is GAESA (Grupo de Administración Empresarial, S.A.), a conglomerate associated with Cuba’s armed forces that has historically had a significant footprint in tourism, retail, logistics, and real estate. If a counterparty is on the Cuba Restricted List or otherwise prohibited, U.S. persons cannot engage in direct financial transactions with it even if the activity sounds ordinary.
At the same time, Cuba’s domestic private sector has expanded in recent years. A MIPYME is a micro, small, or medium-sized enterprise recognized under Cuban law. For some business models, working with independent private firms may reduce certain restricted-list risks—though it does not automatically solve U.S. licensing, payment, export-control, or due-diligence issues. See /sectors/private-sector for a sector primer.
Currency and pricing also matter for feasibility. Cuba uses the Cuban peso (CUP), and some retail channels price in MLC (moneda libremente convertible, a “freely convertible currency” concept used for certain domestic transactions). Because multiple exchange rates and informal markets can coexist, investors and operators often need to model cash flows using more than one rate assumption.
A commonly referenced informal-market benchmark is the TRMI (tasa representativa del mercado informal), a representative informal market exchange rate popularized by independent Cuban data sources. For rate context and historical series, see /tools/eltoque-trmi-rate. The central bank, the BCC (Banco Central de Cuba), may also publish various official or special rates, which can diverge materially from informal pricing.
Common questions investors and journalists ask (and the non-technical answers)
Is the embargo a total ban?
No. It is a broad restriction with defined exceptions. Some categories of travel, remittances, information/telecom services, humanitarian support, and limited trade may be authorized under GLs or specific licenses. The difficulty is that the permitted channel must match the text of the authorization, and counterparties must not be prohibited.
What’s the difference between OFAC lists and the Cuba Restricted List?
OFAC maintains sanctions lists that apply across programs. Cuba also has Cuba-specific constraints implemented via the CACR and State Department lists, notably the Cuba Restricted List (no direct financial transactions by U.S. persons) and the Prohibited Accommodations List (travel-related). In real compliance programs, companies screen against multiple sources and then apply the strictest applicable rule.
Do these rules matter if I’m not American?
Often, yes. Even a non-U.S. investor can be affected if a deal uses U.S. dollars, touches U.S. banks, involves U.S. shareholders or staff, relies on U.S.-origin goods/technology, or includes U.S. service providers (legal, accounting, cloud, payments). The practical risk is less “OFAC will regulate you directly” and more “your transaction becomes unserviceable in the global financial system.”
How does Helms-Burton fit in?
The Helms-Burton Act (a U.S. law) is separate from the CACR but shapes the overall embargo framework. It matters particularly for legal risk around property claims and “trafficking” in confiscated property (often discussed as Title III risk). That risk can influence foreign investors’ willingness to enter sectors such as /sectors/real-estate and /sectors/tourism, even if the investor is not a U.S. person.
What to do next: a practical compliance workflow
If you’re assessing a Cuba-linked transaction—whether as an investor, reporter, NGO, or service provider—use a simple workflow:
- Define the actors: who is the U.S. person (if any), who are the Cuban counterparties, who are the beneficial owners, and who touches funds or services.
- Screen lists early: check counterparties against the Cuba Restricted List and related prohibitions, then document results. Start with /tools/ofac-cuba-sanctions-checker.
- Map the authorization: identify which GL (if any) fits the exact activity. Use /tools/ofac-cuba-general-licenses as a starting point, then confirm against the primary legal text.
- Stress-test payments: confirm whether banks, insurers, shippers, and platforms will process the transaction. “Legal” is not the same as “bankable.”
- Model economics realistically: incorporate currency conversion and rate uncertainty. For scenario analysis, see /tools/cuba-investment-roi-calculator and rate context at /tools/eltoque-trmi-rate.
