- US designates Cuban state oil firm CUPET as Specially Designated National

US Sanctions Force Melbana to Halt Cuban Project Activities
Melbana Energy Limited (ASX:MAY) has paused its direct financial, technical, and administrative support for its Cuban Block 9 Production Sharing Contract (PSC) following the US Department of State’s designation of Cuba’s state-owned oil and gas company Unión Cuba-Petróleo (CUPET) as a Specially Designated National (SDN). This move, under Executive Order 14404, restricts US entities from transacting with CUPET and raises the spectre of secondary sanctions for non-US parties, including Melbana.
The designation of CUPET, Melbana’s contractual partner and PSC counterparty, complicates the operator’s ability to continue its Cuban operations. While Melbana and its subsidiaries are not themselves designated, the company has taken a cautious approach, suspending active participation in the project pending a detailed legal and regulatory review.
Operations Already Dormant Amid Partner Funding Default
Operational activity in Block 9 had effectively ceased since late 2025 due to the non-payment of cash calls by Melbana’s joint venture partner, which triggered the departure of all expatriate personnel and contractors from Cuba. Despite this, Melbana maintained site safety and security through local Cuban contractors. The new US sanctions have now forced the company to suspend even this limited involvement.
This suspension follows a series of setbacks stemming from the partner’s financial default, which had already delayed planned drilling and exploration activities. Melbana had been moving to regain full control of the asset after its partner failed to meet funding obligations, a situation that has been unfolding for several months and was documented in prior disclosures partner default and seismic insights.
Navigating a Complex Sanctions Landscape
Melbana is actively consulting with legal counsel and sanctions experts to interpret the implications of the Executive Order on its Cuban operations. The company acknowledges the technical complexity of the US sanctions framework, especially concerning potential secondary sanctions risks for non-US operators like itself.
These discussions are ongoing, and Melbana has not yet determined a definitive course of action. It is also exploring whether it can seek formal clarifications from the US Treasury’s Office of Foreign Assets Control (OFAC) or the State Department to potentially resume operations under compliant conditions.
Australian Assets Remain Unaffected
Importantly for investors, Melbana’s portfolio of exploration licences in Australia remains unaffected by the US sanctions on CUPET. The company continues to hold and develop these assets independently of its Cuban operations.
Following the announcement, trading in Melbana’s shares was reinstated on the ASX, ending a brief suspension imposed to facilitate the market’s assessment of the sanctions impact.
Bottom Line?
Melbana faces a tangled regulatory and operational challenge in Cuba that could stall its Block 9 ambitions indefinitely, with the resolution hinging on complex US sanctions interpretations and partner dynamics.
Questions in the middle?
- How will Melbana mitigate the risk of secondary US sanctions while maintaining its Cuban interests?
- What are the prospects for Melbana regaining full operational control or exiting the Cuban PSC?
- Could Melbana’s Australian assets become a strategic focus amid Cuban uncertainties?
