Three fully laden oil supertankers moved through the Strait of Hormuz on Saturday, offering the clearest sign yet that crude shipments may be starting to recover after weeks of disruption triggered by confrontation between the United States and Iran. Vessel tracking data cited by multiple reports showed two China-flagged very large crude carriers and one Liberia-flagged tanker leaving the Gulf, while several empty tankers were also heading in to load cargoes. The passage matters far beyond the Gulf. The narrow waterway handles about a fifth of global oil and liquefied natural gas trade, making even a partial reopening critical for refiners, traders and governments watching for any change in supply flows. Shipping through the strait had fallen to a fraction of normal levels after the conflict erupted in late February, leaving hundreds of vessels delayed and helping to drive a sharp rise in crude and fuel prices.
The tankers identified in tracking data were Cospearl Lake and He Rong Hai, both linked to Chinese trade, and Serifos, a Liberia-flagged vessel chartered by Thailand’s PTT. Reports said Cospearl Lake was carrying Iraqi crude and was bound for Zhoushan in China, while He Rong Hai was loaded with Saudi crude. Serifos was reported to be heading towards Malaysia. Their movement marked the first transit by loaded supertankers since the shipping crisis deepened, suggesting some operators now see a narrow window to move cargo under the protection of a fragile ceasefire.
That shift does not amount to a full restoration of maritime confidence. Only days earlier, traffic through Hormuz was described as being at a near standstill, with vessels told to stay close to Iranian waters near Larak Island because of naval mine risks. Several shipping companies have kept a cautious stance, arguing that a ceasefire on paper is not the same as reliable security at sea. Maersk, among the world’s biggest container lines, said this week that the truce may create transit opportunities but still offered no full maritime certainty.
Military developments remain central to the outlook. The U. S. military said two of its warships had passed through the strait as part of efforts to set conditions for mine-clearing operations. President Donald Trump said U. S. forces had started removing mines and claimed Iran’s mine-laying boats had been destroyed, though the broader picture remains difficult to verify independently in full. What is clear is that commercial shipping is still moving through a highly militarised corridor in which insurers, charterers and shipowners must weigh political signals against the physical risk to crews and cargo.
Diplomacy has offered only limited reassurance. Talks between Washington and Tehran in Islamabad ended without a breakthrough, despite both sides signalling support for keeping the ceasefire alive. The gap between the two governments remains wide, with disputes over Iran’s nuclear programme, war damage and control over Hormuz still unresolved. Even so, the fact that tankers have started to move while diplomacy continues suggests the market is responding not to a settled peace, but to a temporary reduction in the immediate danger of interruption.
For Asian buyers, the resumption of any Gulf traffic is especially significant. China remains a major customer for crude from the Middle East, and the reappearance of China-bound tankers underscores how quickly consuming nations will try to restore supply chains once a route looks passable. Gulf producers, meanwhile, need exports to resume to stabilise revenues and reassure customers that long-term contracts can still be honoured despite the conflict. The return of empty tankers into the Gulf to load oil is as important as the departure of the laden ships, because it points to tentative confidence that the route may stay open long enough for another cycle of trade.
Oil traders are unlikely to treat Saturday’s movements as proof that the crisis has passed. Prices remain sensitive to every military or diplomatic update, and analysts have warned that even with some transit restored, the supply shock from weeks of blockage and conflict will continue to ripple through energy markets. The strait’s vulnerability has again highlighted how a single maritime bottleneck can reshape freight costs, insurance rates and fuel bills from Asia to Europe and North America.
Iran’s attempt to direct shipping through specific lanes and the wider debate over whether it can impose any form of toll or control over passage have also added a legal and commercial layer to the crisis. Maritime experts note that freedom of transit through international straits is a core principle of global trade, and any attempt to formalise extra charges or unilateral restrictions would alarm shipowners well beyond the Gulf. That means the story is no longer only about whether tankers can pass, but under what rules, at what cost and with what degree of outside naval protection.
