Lead: The U.S. Coast Guard is intercepting a sanctioned vessel on Dec. 20, 2025, in international waters of the Caribbean Sea off Venezuela, three U.S. officials told reporters. The operation is ongoing and authorities have not yet released the ship’s name or precise coordinates. If confirmed, this would be the second sanctioned tanker seized by U.S. forces this month after the Dec. 10 boarding of the oil tanker The Skipper. U.S. pressure on Venezuelan oil shipments has escalated amid threats from President Donald Trump to bar sanctioned tankers from Venezuelan ports.

Background
Since 2019 the United States has applied a range of economic sanctions on Venezuela and entities linked to its oil sector, citing allegations of corruption and the diversion of oil revenues. Washington has targeted individual vessels, shipping companies and tanker operators alleged to be involved in illicit transfers or evasion of sanctions. Those measures have included designation on sanctions lists, asset freezes and, in some cases, interdiction at sea.
On Dec. 10, 2025, a U.S. Coast Guard tactical operations team boarded and seized The Skipper, an oil tanker sanctioned for participating in an illicit oil operation tied to Venezuela. That boarding—carried out with support from U.S. Navy helicopters—marked a notable operational escalation, signaling that interdictions would not be limited to port inspections or penalties on companies. The U.S. has increasingly framed such actions as enforcing international sanctions and curbing illicit trade routes.
Main Event
Three U.S. officials told reporters that, on Dec. 20, a Coast Guard interdiction is underway against a vessel that is under U.S. sanctions. Officials declined to identify the vessel name or give precise coordinates, saying operational security measures were in place. The interdiction is taking place in international waters of the Caribbean Sea off the Venezuelan coast.
U.S. authorities have not publicly confirmed what assets are directly supporting the current boarding or seizure beyond the statement that the Coast Guard is conducting the operation. The Dec. 10 seizure of The Skipper did involve a joint Coast Guard–Navy effort; whether similar Navy support is present for the Dec. 20 operation remains unreported. Media outlets cited anonymous U.S. officials for initial details.
President Donald Trump amplified Washington’s posture this week with online posts threatening a blockade on sanctioned tankers entering or leaving Venezuela, language that U.S. officials say is part of pressure campaign to restrict the Maduro regime’s oil revenues. Venezuelan President Nicolás Maduro responded by denouncing U.S. aims as attempts at regime change and reiterating Venezuela’s intent to continue oil commerce.
Analysis & Implications
The apparent second interdiction in ten days suggests U.S. enforcement of sanctions has moved into a phase of operational interdictions at sea rather than relying solely on diplomatic and financial levers. That shift raises legal, operational and geopolitical questions: interdictions in international waters must balance U.S. domestic law, international maritime law and the risk of escalation with Venezuelan-aligned actors.
Operationally, interdictions require precise intelligence, boarding teams trained for maritime seizures, and often aerial or surface support. If the Coast Guard continues similar actions, it will need sustained logistics, legal review of evidence establishing sanctions violations, and clear chains of custody for seized cargo and crews. The Dec. 10 operation set a tactical precedent; a second action could indicate a campaign approach rather than an isolated enforcement event.
Politically, these moves will likely heighten tensions between the U.S. and the Maduro government and could complicate third-party shipping firms’ willingness to operate in the region. Firms and insurers may reroute shipments or suspend services to avoid entanglement, further constraining Venezuela’s oil exports. International partners and maritime industry stakeholders will watch U.S. legal justifications and the transparency of evidence used in interdictions.
Comparison & Data
| Date | Vessel | Alleged Reason | Reported U.S. Assets |
|---|---|---|---|
| Dec. 10, 2025 | The Skipper | Sanctioned for participating in illicit oil operation involving Venezuela | Coast Guard tactical team; U.S. Navy helicopters |
| Dec. 20, 2025 | Unnamed sanctioned vessel (reported) | Listed on sanctions; specifics not publicly released | Coast Guard interdiction (support assets unreported) |
The table summarizes public reporting to date: the Dec. 10 seizure is confirmed with tactical and aviation support, while details on the Dec. 20 interdiction remain limited. Analysts caution that absent official disclosures about evidence or custody procedures, the interpretation of tactical patterns is provisional.
Reactions & Quotes
U.S. political leadership has framed stronger measures as necessary to uphold sanctions and deny revenue streams to the Maduro government. Officials emphasize enforcement actions are targeted at entities violating U.S. sanctions and are carried out under legal authorities governing maritime interdiction.
“Venezuela is completely surrounded by the largest Armada ever assembled in the History of South America… It will only get bigger.”
President Donald Trump (social media post)
The White House rhetoric has been vocally hawkish this week; senior administration aides describe the messaging as aimed at deterring further sanction evasion. Critics caution that militarized language risks escalation and may complicate diplomatic avenues for de-escalation.
Venezuelan leadership has rejected U.S. actions and framed them as attempts at political overthrow, while promising to continue commercial ties with partners prepared to trade with Caracas.
“This will just not happen, never, never, never — Venezuela will never be a colony of anything or anyone, never.”
President Nicolás Maduro (public statement)
Maduro’s statement positions the government to rally domestic and allied international support. Observers say such rhetoric is consistent with previous Venezuelan responses to intensified U.S. pressure.
Unconfirmed
- The exact name and flag registry of the vessel currently being seized have not been publicly confirmed by U.S. authorities.
- Whether U.S. Navy helicopters or other Naval assets are participating in the Dec. 20 interdiction has not been independently verified.
- Details tying this specific vessel to a named illicit oil network or precise sanctions designation have not been released.
- Any information about crew nationality, use of falsified documents, or specific cargo manifests remains unreported.
Bottom Line
The reported interdiction on Dec. 20, 2025, if confirmed, signals a continued and potentially escalatory U.S. enforcement approach to Venezuelan oil sanctions following the Dec. 10 seizure of The Skipper. Operational patterns will be clearer if U.S. authorities release vessel identity, legal grounds for seizure and evidence of sanction breaches.
For regional stability and international shipping, the key questions are legal transparency and predictable procedures: clear public explanations of the basis for interdictions will shape how other states, insurers and commercial operators respond. Watch for official U.S. statements, any subsequent legal filings about the vessel and reactions from international maritime stakeholders in the coming days.
