The M/T Skipper seized by U.S. Coast Guard, was a sanctioned crude-oil tanker previously identified as part of an oil shipping network supporting Lebanese group Hezbollah and Iran’s Islamic Revolutionary Guard Corps' Quds Force, both U.S.-designated terrorist organizations.

Along with the blockade, Trump said he has formally designated Venezuela's Maduro and his government allies a foreign terrorist organization.

It comes a week after the US seized an oil tanker off the coast of Venezuela, in a move that intensified pressure on its government.

The Trump administration plans to hold the oil tanker it seized in waters near Venezuela at an American port in Texas but release the crew once the vessel docks, according to two U.S. officials. The officials said the tanker was seized in international waters.

The cost of shipping oil is likely to remain high in the first half of 2026 as the global fleet ages and a rising number of vessels are hit with Western sanctions, shipping sources say, though rates could be capped in the second half.
