Second sanctioned tanker enters Gulf amid US Iran blockade tensions

A second US-sanctioned supertanker has entered the Gulf through the Strait of Hormuz despite ongoing US restrictions on vessels linked to Iranian oil trade, according to shipping data and media reports.

Data from maritime tracking platforms showed the empty Very Large Crude Carrier (VLCC) RHN entering the Gulf, following a similar movement by another sanctioned tanker earlier in the week. The vessel is capable of carrying up to 2 million barrels of crude oil, although its exact destination remains unclear.

The development comes amid heightened tensions after the United States imposed a naval blockade on ships visiting Iranian ports, following the collapse of recent US-Iran negotiations held in Islamabad. The US administration has stated that the blockade aims to restrict Iran’s ability to export oil and apply pressure in ongoing diplomatic efforts.

According to US Central Command, several vessels have been redirected since the blockade began, and no ship has successfully breached the restrictions so far. However, conflicting reports from Iranian media suggest that some tankers have still managed to pass through the Strait and continue their voyages toward Iranian ports.

Shipping analytics firms noted that both recently observed tankers have previously transported Iranian crude, highlighting continued attempts to move oil despite sanctions pressure. One of the vessels is reportedly heading toward regional destinations, while others have been forced to turn back under US direction.

The Strait of Hormuz remains one of the world’s most critical energy chokepoints, handling a significant share of global crude oil and liquefied natural gas shipments. Any disruption in this route has a direct impact on global energy markets and oil prices.

Analysts say that while Iran may maintain current production levels in the short term using storage facilities, sustained restrictions on maritime exports could gradually tighten supply and increase market volatility.

Diplomatic sources suggest that indirect negotiations between the US and Iran may continue, with possible mediation efforts being explored to prevent further escalation and ensure safe passage of commercial shipping in the region.
