U.S. stops major oil shipment heading to Cuba from near Venezuela

 December 11, 2025

The U.S. government intercepted a massive oil tanker this week off the coast of Venezuela in a high-stakes move with global implications.

The vessel, called Skipper, was seized under a federal warrant after allegedly disguising its origin and destination while transporting crude oil reportedly tied to illicit Iranian sources, Breitbart News reported.

President Donald Trump revealed the seizure Wednesday afternoon, describing the ship as “very large” and suggesting it might be the biggest vessel ever taken under such circumstances. According to Trump, the tanker was on its way to Cuba, a close ally of both Iran and Venezuela in circumventing sanctions.

Seizure Marks Bold Action In Straitened Waters

“We’ve just seized a tanker on the coast of Venezuela,” Trump said in a press statement, before adding, “Other things are happening. So, you’ll be seeing that later.” His remarks were intentionally vague, but the signal was loud and clear: the U.S. is prepared to enforce its sanctions policy, even on the high seas.

A U.S. official later confirmed that the Coast Guard led the operation, with backing from the Navy. The seizure had been legally authorized through a federal judge’s warrant issued about two weeks before the action.

At the time of its capture, the tanker was said to be sailing under a deceptive flag—an alleged attempt to obscure its true nationality and ties. Such tactics are straight out of the smuggler’s playbook, long favored by those pushing sanctioned oil into the global market through back channels.

Shipping Tactics Expose Illicit Oil Trade

The ship’s cargo, unremarkably, was crude oil—though the issue wasn’t the oil itself but the way it was being moved. Officials say the tanker, formerly known as Adisa, had past connections to Iranian oil smuggling operations and had previously been sanctioned by the U.S. Treasury.

A source familiar with the tanker’s route told Politico that the oil was headed for Cuba, with Cuba’s state firm Cubametales planning to offload it and reroute it to brokers in Asia. Though sanctioned heavily, Cuba still quietly participates in deals that benefit fellow authoritarian regimes, often relying on stealth and plausible deniability.

Trump was asked what would happen to the oil now that it was in American hands. His answer, while brief, summed up the administration’s confidence: “Well, we keep it, I guess.” That’s one way to pour cold water on black-market ambitions.

Maduro, As Expected, Responds With Fury

Interestingly, officials clarified that the seizure had nothing to do with the ship’s Venezuelan oil holdings or affiliations with Nicolás Maduro’s regime. The issue, they explained, stemmed solely from the vessel’s previous activities involving illegal Iranian oil shipments.

Still, Maduro didn’t miss the opportunity to use the situation to stoke nationalist fervor. “Prepared to break the teeth of the North American empire, if necessary,” the Venezuelan strongman grumbled in a televised address on the same day as the seizure was made public.

The bluster was predictable, and so was the lack of actual protest. For all Maduro’s saber-rattling, what matters more to markets is whether the maneuver disrupts the already narrow pipeline of Venezuelan crude reaching the few buyers willing to stand up to sanctions.

Markets React Cautiously To Developments

International oil prices edged up in response to the news, suggesting traders are wary of any disruption to the fragile flow of sanctioned crude. But according to analysts, global buyers remain cautious and stopped short of making major adjustments pending further details.

“The real question is whether this marks a broader enforcement wave or a one-off event,” said one energy strategist, noting that the specifics of the cargo and intended recipients could shift future market calculations.

For now, it appears to be a message—in action, not just in words—that the United States is prepared to back up sanctions with more than diplomacy. The ocean isn’t a lawless frontier anymore, not when federal warrants carry enough weight to reroute ocean freighters mid-voyage.

As far as policy signals go, this one carries ballast. It's not just about oil, or Cuba, or smuggling. It's about reaffirming national priorities and redrawing boundaries—in this case, maritime ones—with a steady hand and a clear purpose.
