Iran announced Friday, April 17, 2026, that the Strait of Hormuz is “completely open” to commercial vessels for the remainder of the ceasefire period, linking the reopening directly to the 10-day Israel–Lebanon truce that went into effect at midnight Thursday. Foreign Minister Abbas Araghchi posted on X that passage is declared open “in line with the ceasefire in Lebanon,” and ships must use a “coordinated route” announced by Iran’s Ports and Maritime Organisation. President Trump quickly amplified the news, posting “IRAN HAS JUST ANNOUNCED THAT THE STRAIT OF IRAN IS FULLY OPEN AND READY FOR FULL PASSAGE. THANK YOU!”
The reopening follows nearly seven weeks of de facto closure after the U.S. and Israel launched their war on Iran on February 28, 2026. During that period, Iran threatened to strike ships tied to U.S. allies, began charging tolls, and restricted traffic to a trickle. The Strait normally handles about one-fifth of the world’s oil and LNG — roughly 120-140 daily transits — but fell to single-digit passages per day, with more than 600 vessels, including 325 tankers, stranded in the Gulf.
Iran’s announcement came with conditions. A senior Iranian official told Reuters that all ships can sail but “this needs to be coordinated with Iran’s Islamic Revolutionary Guard Corps (IRGC),” and military vessels remain prohibited. Transits are restricted to lanes Iran deems safe, with authorisation required from both the IRGC and Iran’s Ports and Maritime Organization. Iran’s parliament speaker Mohammad Baqer Qalibaf warned the strait “will not remain open” if the U.S. naval blockade of Iranian ports continues.
The market reaction was immediate. Oil prices tumbled Friday as traders unwound the war risk premium: WTI crude fell nearly 10% to close at $85.57, the lowest in over a month, while Brent dropped 6% to $92. Reuters reported Brent settled down $9.01, or 9.07%, to $90.38 after touching $86.09 intraday. The S&P 500 energy sector slid 3%, while airlines and cruise operators — big fuel users — rallied. The Dow surged over 1,000 points.
Vessel movement resumed quickly but cautiously. Around 20 ships were seen exiting the Gulf via Hormuz on Friday, and three supertankers — Serifos, Cospearl Lake, and He Rong Hai — transited Saturday. Each can carry 2 million barrels. A convoy of four LPG carriers plus oil product and chemical tankers crossed Iranian waters south of Larak Island on Saturday, the first major movement since the war began. Still, shippers and the IMO said clarity was lacking. The IMO secretary-general noted they were “verifying the announcement… in terms of its compliance with freedom of navigation.
The reopening is tied to broader ceasefire diplomacy. The U.S. brokered a 10-day Israel-Lebanon ceasefire that began Thursday, with direct Israeli-Lebanese talks at the State Department — their first in 30+ years. Iran had made a Lebanon truce a condition for reopening Hormuz, given Hezbollah’s role in the fighting since Oct. 7, 2023. Trump claimed the U.S.-Iran war ceasefire is also in place, though it’s set to expire Tuesday unless extended. He said a U.S. naval blockade of Iranian ships and ports will remain “in full force” until a final deal.
Analysts caution that “full normalization” is still distant. Details on routes, tolls, and duration remain unclear, and Iran tied the opening explicitly to the Lebanon ceasefire’s remaining period — which ends April 26. Rebecca Babin of CIBC Private Wealth noted “headlines are moving a lot faster than barrels.” Iran previously said unfreezing its assets was part of the deal, and shipping costs could jump: reports cite a potential $2 million toll for the 1,500 ships that were stranded.
For now, the reopening eases the largest oil supply shock in history, per the IEA. But with IRGC coordination required, military ships banned, the U.S. blockade ongoing, and ceasefires time-limited, markets are treating it as a tactical breather, not a resolution. Trump said “Iran has agreed to never close the Strait of Hormuz again,” while Iran’s foreign minister framed it as temporary and conditional — underscoring how fragile the arrangement remains.
