An Iranian supertanker, owned by the Iranian national company, breached the U.S. blockade in the Strait of Hormuz, returning to Kharg Island after a 2 million-barrel transfer to another VLCC in Indonesia. The move came just hours before the U.S.–Iran ceasefire expires, sparking immediate market concern. The vessel departed Iran in late March 2026, sailed to the Riau Archipelago in Indonesia, and completed the transfer of 2 million barrels of crude. It then navigated back through the blockade line, with TankerTrackers.com reporting it would reach Kharg Island the following day. Key data from the incident include the 2 million-barrel cargo, the late-March departure, the brief opening of the Strait on Friday that lasted only a few hours, and the subsequent re-closure on Saturday. The breach occurred hours before the ceasefire's scheduled end, heightening uncertainty in oil supply routes. According to the U.S. President, the ceasefire was "highly unlikely" to be extended, adding that he was not rushed into a bad deal and had all the time in the world. Iran's First Vice President warned that security at the Strait of Hormuz comes at a cost, underscoring the strategic stakes of the shipping lane.
