Key points

Iran's Araghchi stated on X: the strait is open on a "coordinated route" announced by Iranian authorities, tied to the Israel-Lebanon truce.[[2]](https://www.bloomberg.com/news/articles/2026-04-17/shipowners-and-oil-traders-wary-as-iran-says-hormuz-fully-open)[[6]](https://x.com/araghchi/status/2045121573124759713)

Shipowners and traders stayed wary, seeking clarity on risks like mines or US enforcement before committing vessels.[[2]](https://www.bloomberg.com/news/articles/2026-04-17/shipowners-and-oil-traders-wary-as-iran-says-hormuz-fully-open)
Traffic had slumped to a trickle since late February war start, with US forces turning back ships to Iranian ports since Monday.[[4]](https://www.insidenova.com/news/national/hormuz-shipping-muted-as-us-blockade-takes-hold-tracking-data/article_10994731-f1af-530c-a36e-b7e457d5b4d4.html)

Details and context

The Strait of Hormuz handles about 20% of global oil trade, so its disruptions since the US-Iran war began late February spiked energy prices and jammed hundreds of vessels inside the Gulf.[[8]](https://www.reuters.com/business/energy/chinese-oil-tankers-transit-strait-hormuz-data-shows-2026-04-11) Iran's initial restrictions, then US blockade of its ports after April 12 peace talks failed, left over 670 commodity carriers signaling west of the strait by mid-week.[[4]](https://www.insidenova.com/news/national/hormuz-shipping-muted-as-us-blockade-takes-hold-tracking-data/article_10994731-f1af-530c-a36e-b7e457d5b4d4.html)

Araghchi's announcement links directly to a 10-day Israel-Lebanon ceasefire starting midnight Thursday, pausing strikes on Iran-backed Hezbollah after heavy casualties.[[9]](https://apnews.com/live/iran-war-israel-trump-04-16-2026) Yet Iranian state TV noted ships still need Revolutionary Guard Corps coordination, adding caution.[[10]](https://x.com/DiveBomb321)

US clarified its blockade hits only Iranian port calls, not all traffic, but Trump insists it holds until nuclear and other issues resolve.[[11]](https://www.aljazeera.com/video/newsfeed/2026/4/16/us-general-clarifies-iranian-ports-under-blockade-not-strait-of-hormuz)

Key quotes

“In line with the ceasefire in Lebanon, the passage for all commercial vessels through Strait of Hormuz is declared completely open for the remaining period of ceasefire.” – Iranian Foreign Minister Abbas Araghchi on X.[[6]](https://x.com/araghchi/status/2045121573124759713)

Why it matters

Control of the strait affects global energy flows from Gulf producers like Saudi Arabia and UAE, with weeks of halts already fueling price surges and economic strain.

This could free trapped oil and ease costs for traders and consumers if traffic resumes steadily, though caution limits quick impact.

Watch tanker transits over the weekend, US-Iran talks possibly resuming soon, and Lebanon truce holding through April 21 – any snag could reverse gains.[[12]](https://www.youtube.com/watch?v=EqiUbmniG6o)
