The U.S. Treasury Department’s latest sanctions announcement may not have generated splashy headlines, but it marks one of the most consequential escalations in the Trump administration’s renewed pressure campaign against Venezuela.

On December 31, Treasury’s Office of Foreign Assets Control (OFAC) announced sanctions against four foreign companies and the blocking of four oil tankers accused of helping Venezuela’s authoritarian ruler, Nicolás Maduro, evade U.S. sanctions by exporting oil through a so-called “shadow fleet.” The message from Washington is clear: the era of looking the other way at sanctions evasion is over.

From Paper Sanctions to Real Enforcement

For years, U.S. sanctions on Venezuela existed largely on paper. Tankers changed names, flags, and owners. Cargoes were blended, transponders switched off, and oil quietly made its way to Asia—especially China—while the Maduro regime collected hard currency.

This time is different.

The Treasury action blocks vessels tied to companies operating out of China and Hong Kong, including Corniola Limited, Krape Myrtle Co. LTD, Winky International Limited, and Aries Global Investment LTD. The sanctioned tankers—NORD STAR, ROSALIND (also known as LUNAR TIDE), DELLA, and VALIANT—were directly linked to transporting Venezuelan oil in violation of U.S. law.

Treasury Secretary Scott Bessent left little room for ambiguity:

“President Trump has been clear: We will not allow the illegitimate Maduro regime to profit from exporting oil while it floods the United States with deadly drugs.”

That framing reflects a broader Trump administration view: Venezuela’s oil revenue is not merely an economic issue but a national security one.

Oil Revenue Is Maduro’s Lifeline

Oil accounts for an estimated 80 to 90 percent of Venezuela’s export earnings. Cut that off, and the regime’s ability to fund patronage networks, security forces, and regional criminal groups shrinks dramatically.

Shipping data suggests the impact is already real. Venezuelan oil exports reportedly fell sharply in December, with loaded tankers idling offshore and buyers suddenly wary of U.S. enforcement. Insurance costs for shadow fleet vessels are rising, while operators face the growing risk of seizure, designation, or interdiction.

This is the core strategic shift: sanctions backed by credible enforcement.

China’s Quiet Calculus

Much of Venezuela’s sanctioned oil ends up in China, often rebranded or routed through intermediaries. Beijing has predictably criticized U.S. actions as “unilateral” and “bullying.” But so far, China’s response has been rhetorical, not material.

That restraint matters. China has loans to Venezuela that are repaid in oil, but it also has far larger interests at stake in avoiding a direct confrontation with Washington. For now, Chinese firms appear more cautious, not defiant—a sign that U.S. pressure is altering behavior, even if quietly.

A Contrast With the Past

Supporters of the renewed “maximum pressure” approach argue it corrects what they see as a fundamental failure of the Biden-era strategy: easing enforcement in exchange for promises that never materialized.

By contrast, the Trump administration has paired sanctions with maritime enforcement, tanker seizures, and explicit warnings to facilitators abroad. The result is deterrence, not symbolism.

Critics warn of humanitarian consequences and escalation risks. Those concerns are not frivolous. But center-right policymakers counter that allowing an entrenched authoritarian regime to fund itself indefinitely through sanctions evasion guarantees long-term suffering, instability, and mass migration.

A Test Case for Sanctions Policy

Venezuela may be the test case for a broader strategy. The same shadow fleet techniques are used by Iran and Russia, often involving overlapping networks of vessels, insurers, and shell companies. If Washington demonstrates that sanctions evasion carries real costs, the ripple effects could extend far beyond the Caribbean.

For now, the takeaway is simple: the Trump administration is signaling that sanctions will be enforced, not merely announced. For Maduro’s regime—and for those who profit from keeping it afloat—that is a meaningful change.

Whether this pressure ultimately forces concessions or accelerates collapse remains to be seen. But one thing is already clear: the shadow fleet is no longer operating in the shadows.
