Some oil tankers have changed course away from Venezuela after President Donald Trump threatened a “blockade” of sanctioned ships entering or leaving the South American country.
Trump said Tuesday on social media, in all caps, that he is ordering a "total and complete blockade of all sanctioned oil tankers” into and out of Venezuela, a move that threatens to choke off revenue from the world's largest oil reserves that are key to Maduro's grip on power.
It’s not clear exactly what Trump meant by his threats.
U.S. sanctions adopted during his first administration makes it illegal for Americans to purchase Venezuela’s crude oil without a license from the Treasury Department.
Additionally, hundreds of ships themselves have been sanctioned — part of a massive shadow fleet of often aging vessels that has proliferated in recent years to transport oil on behalf of Iran, Russia, Venezuela and other U.S. adversaries under sanctions.

A few have started to change their course, perhaps fearing they could face the same fate as the Skipper, a sanctioned vessel seized by U.S. forces last week near Venezuela.
“It’s quite clear that this has disrupted energy flows to and from Venezuela,” said Michelle Wiese Bockmann, a senior analyst at Windward.
"Every hour when we’re tracking these vessels, we are seeing tankers that are deviating, loitering or changing their behavior.”
Among those is the Hyperion, which had been sailing toward the Jose port in Venezuela before doing a 90-degree turn early Wednesday and starting to head north away from the South American mainland.
The vessel, previously part of Russia’s state-owned shipping fleet, was one of 173 sanctioned in the final days of the Biden administration for allegedly facilitating Russian oil sales in violation of sanctions over Moscow’s invasion of Ukraine.
Following the penalties, the vessel changed its flag from the Comoros to Gambia. But the West African nation deleted Hyperion — along with dozens of other vessels — from its privately run ship registry in November for allegedly using false certificates claiming to have been issued by its maritime authority.
The vessel’s ownership also is obfuscated under multiple layers of offshore companies, some of them listed in Dubai, United Arab Emirates.
“It’s just screaming that it’s in a position to be seized,” Wiese Bockmann said.
