On December 23, 2025, the Panama-flagged supertanker Kelly reversed course and returned to Venezuelan state-controlled waters fully loaded, following an escalation in U.S. maritime enforcement actions. The move comes as the U.S. Coast Guard intercepted multiple tankers carrying Venezuelan crude, including the Panama-flagged tanker Centuries loaded with nearly 1.9 million barrels of Merey heavy crude, as Washington applies heightened pressure on President Nicolas Maduro’s government.

Supertanker Kelly’s Return Reflects Heightened Sanctions Enforcement

After departing Venezuela days earlier, Kelly was tracked re-entering waters near the PDVSA-operated Amuay port, according to TankerTrackers.com. Kelly and Centuries left Venezuela almost simultaneously last week, escorted by Venezuelan naval vessels. However, following Centuries’ interception by the U.S. Coast Guard on December 20, and pursuit of an empty tanker en route to Venezuela, Kelly’s return underscores the increasing challenges faced by Venezuela’s oil exports amid U.S. sanctions enforcement.

Currently, over a dozen other tankers fully loaded with Venezuelan crude remain anchored offshore awaiting guidance from their operators. This bottleneck has intensified since the earlier seizure of the supertanker Skipper by U.S. authorities earlier this month and subsequent actions against additional vessels over the weekend.

Political and Market Implications of the U.S. Blockade

Last week, U.S. President Donald Trump announced a formal blockade targeting all vessels under sanctions entering or leaving Venezuelan ports, aiming to tighten the economic siege on the Maduro administration. This measure arrives amid deepening economic and political instability in Venezuela.

Adding complexity to the situation, maritime authorities in Guyana and Panama have raised alarms over unauthorized use of national flags and violations of maritime regulations. Guyana’s maritime authority revealed that at least one tanker targeted by the U.S. was flying a false Guyanese flag, while Panama’s foreign affairs minister stated some intercepted ships failed to comply with Panama’s maritime laws.

The disruption of Venezuelan crude exports—a crucial revenue source for state oil company PDVSA—could contribute to tighter oil supply conditions globally. Market participants remain alert to further U.S. enforcement and Venezuela’s responses as geopolitical tensions continue to shape energy flows.

Supertanker Activity Signals Ongoing Logistical Strains

The supertanker Kelly’s return fully laden to Venezuelan waters highlights the operational hurdles that Venezuela faces amidst U.S. sanctions. The standstill experienced by multiple loaded vessels off its coast exacerbates uncertainty within shipping and trading circles. Given that Centuries carried approximately 1.9 million barrels of Venezuelan heavy crude when intercepted, the blockade represents a significant deterrent to Venezuela’s oil export capacity.

Energy market observers and investors will monitor developments closely as the U.S. blockade persists into early 2026. The situation underlines the growing geopolitical risks and complexities surrounding Venezuelan crude shipments and global energy security, with the supertanker movements central to ongoing trade and diplomatic dynamics.
