At least three Iranian tankers carrying nearly five million barrels of crude oil have exited the U.S. Navy blockade in the Strait of Hormuz, marking the first such outbound shipment in two months. This movement comes as shipowners cautiously reposition vessels ahead of an expected U.S.-Iran deal signing in Geneva on Friday [1]. Two supertankers, Diona and Hero 2, both owned by the National Iranian Tanker Company and under U.S. sanctions, transported a combined total of 3.8 million barrels of Iranian crude oil, while a third Iran-linked tanker carried 1 million barrels out of the blockade line on Wednesday, according to shipping data from Kpler [1].
The U.S. and Iran signed a Memorandum of Understanding on Monday to end the nearly four-month war, with a formal signing ceremony scheduled for Friday in Geneva. Although the details of the pact have not been disclosed, it is expected to reopen the Strait of Hormuz and waive sanctions on Iran's oil sales. The Wall Street Journal reported that Washington would allow Tehran to immediately begin selling oil and fuel once the agreement is signed, in exchange for Iran's commitment to curb its nuclear program [1].
The Strait of Hormuz, which previously handled about a fifth of the world's oil flow, has been effectively shut during the conflict, with the U.S. Navy blockading Iranian ports and targeting vessels linked to adversarial nations. This has stranded hundreds of ships and disrupted global energy flows [1]. The prospect of reopening the strait has prompted some shipowners, affected by months of surging freight costs and high war-risk insurance premiums, to begin repositioning vessels toward Gulf ports in anticipation of increased restocking demand. However, most shipowners remain cautious, with the maritime sector treating the news with 'wary disbelief' rather than celebration, according to Lloyd's List Intelligence [1].
Insurers are maintaining high war-risk premiums and are demanding 'solid evidence' that the waterway will remain safe before adjusting their rates. Lloyd's analysts noted that while a pause in hostilities could free stranded mariners and boost tanker and bulk markets, the sector views this as a fragile reprieve rather than a return to normality [1]. Some very large crude carrier (VLCC) owners are seeking a 'first-mover advantage' by positioning tankers toward the Middle East Gulf, while others are holding back. Dozens of VLCCs have sailed from the South China Sea and across the Indian Ocean toward United Arab Emirates ports, where at least 30 ships are already at anchor [1].
CONCLUSION
The exit of Iranian tankers from the U.S. blockade signals a potential reopening of the Strait of Hormuz and a resumption of Iranian oil exports, pending the formal signing of a U.S.-Iran deal. While some market participants are preparing for a surge in activity, the overall sentiment remains cautious, with insurers and shipowners awaiting concrete assurances of safety. The situation represents a significant but tentative shift in global energy flows and maritime trade.
