Cuban Assets Control Regulations (US, 1963)

The Cuban Assets Control Regulations in 31 CFR Part 515 are the principal long-running US Treasury regulations governing blocked Cuban property and transactions involving Cuba or Cuban nationals under defined conditions. They remained in force as at 30 July 2026.

CACR structure

The regulations derive from the Trading with the Enemy Act (United States, 1917) and followed Proclamation 3447 (US, 1962). They contain prohibitions, definitions, general licences, specific-licence procedures, exemptions and reporting duties. The legal result depends on the person, property, transaction, location and applicable authorisation.

Blocking property is not the same as a simple transaction ban. Blocked property must be held subject to OFAC rules, while other conduct may be prohibited without creating the same property status. Export licensing can also involve Commerce authorities outside Part 515. The Foreign Assets Control Regulations (US, 1950) are a separate historical instrument.

2026 programme layer

Executive Order 14404 of 1 May 2026 created a separate programme under the International Emergency Economic Powers Act (1977). OFAC FAQ 1251 explains the new authority. Cuba General Licence 1 authorises transactions otherwise prohibited by the executive order to the extent they are authorised or exempt under the CACR.

This coordination does not merge the two legal layers. A CACR authorisation must be read against the executive order, General Licence 1 and any blocked-person consequences. A transaction may also encounter export-control, immigration or other statutory rules.

Assessment

The CACR have changed repeatedly through amendments and licensing policy. Historical restrictions should not be projected onto current travel, remittance, telecommunications or humanitarian permissions. Publication-day review must confirm the current Part 515 text, general licences, FAQs and designations.

Claims about economic effect require a defined outcome and counterfactual. Trade, remittances, investment and domestic policy can move for several reasons. Neither duration nor breadth alone proves compellence, deterrence or harm at a stated magnitude.

Editors should separate legal scope, implementation, enforcement and strategic effect. Any allegation of evasion or prohibited conduct requires attribution to the competent authority and the relevant procedural posture.

Compliance sequence

A transaction review should identify every party, ownership interest, location, property type, payment route and US nexus. The reviewer then checks the Part 515 prohibition, definition, exemption and general licence before considering a specific licence. A general licence authorises conduct within its terms without an application; it does not remove recordkeeping conditions or authorise conduct outside its scope.

Financial institutions may need to distinguish a blocked transfer from a rejected transfer. The operational treatment depends on the governing provision and property interest. Exporters also need to determine whether Commerce authorisation is required for goods or technology, even where an OFAC licence permits the financial transaction.

Remittances, travel-related transactions, telecommunications and humanitarian activity can have separate authorisations. Editors should not describe the whole programme through one category. Any designation under the 2026 executive order must be checked independently from Cuba's general country restrictions.

Current-effect claims should specify the regulated flow and period. A fall in trade may reflect licensing, supply, demand, finance or Cuban domestic conditions, so legal scope and economic attribution should remain separate.

September 2026 amendments

Two OFAC final rules took effect on 30 September 2026. One amended part 515 to implement portions of presidential Cuba policy, including directions in the 2025 National Security Presidential Memorandum 5. The other introduced the Cuba Sanctions Regulations at 31 CFR part 516 to implement EO 14404. Section 516.101 makes the two parts distinct; the new part was issued in abbreviated form with additional regulations contemplated. Each applicable prohibition and authorisation therefore needs separate checking. Part 515 final rule, 91 FR 61741; Part 516 final rule, 91 FR 61748.

The September amendment replaced the professional-meetings general licence with limited winding-down authorisation. Section 515.564(a)(2)(i) covers persons subject to US jurisdiction who were in Cuba on 30 September 2026 to attend or organise professional meetings or conferences, for a trip consistent with the provision as it stood on 30 June 2025, provided they depart Cuba no later than 30 October 2026. Subparagraph (ii) separately authorises, until 30 October 2026, transactions ordinarily incident and necessary to terminating and obtaining refunds for a qualifying trip. The text specifies these dates without an hour or time zone. Final rule, section 515.564(a)(2).

These provisions do not extend every travel category or remove the separate restrictions on financial transactions, accommodation and recordkeeping. Section 515.564(a)(1) retains a conditional professional-research general licence, while paragraph (e) provides a separate case-by-case specific-licence route for the specified research and professional-meeting transactions. OFAC FAQ 1275 repeated the 30 October dates when checked on 31 October 2026. This dated text does not establish that a particular traveller qualified, departed or obtained a refund, and subsequent authorisations require separate checking. Final rule, section 515.564(a) to (e); OFAC FAQ 1275.
