When Will the Strait of Hormuz Reopen?
Updated 9 Oct 2026 · Day 223 of the closure
Short answer: not on any agreed date. Iran has put a seven-day reopening roadmap on the table, Washington has publicly rejected it, and the talks are now running through mediators. Prediction markets put the odds of traffic returning to normal before 31 December 2026 at roughly 20%, and closer to a coin flip by mid-2027.

Where the reopening talks stand (5 Oct 2026)
- Iran’s offer: a seven-day roadmap under which Tehran would reopen the strait and resume nuclear talks within a week if the US lifts its naval blockade of Iranian ports and waives oil sanctions (Al Jazeera).
- US response: President Trump said on 26 September, “I rejected their deal” (CNN, Washington Post).
- Still alive: Foreign Minister Araghchi says Iran is waiting for a “definitive” answer through mediators, with Qatar carrying proposals to Washington (Irish Times).
- On the water: attacks are continuing — the LR2 tanker Lipsi was struck on 4 October, one of up to four attacks JMIC listed in the 72 hours to 4 October — and Iran’s Persian Gulf Strait Authority blacklist stood at 81 vessels (Windward, 2 Oct). On 4 October parliament speaker Ghalibaf said the strait will not reopen until the US meets Tehran’s seven conditions.
Every failed reopening so far
The strait has “reopened” on paper several times since February. Each time, it closed again within days or weeks.

What the betting markets say
Real-money prediction markets are the cleanest read on expected timing. As of 29 September 2026:
- Polymarket — traffic back to normal by 31 Dec 2026: ~22%.
- Kalshi — IMF PortWatch 7-day average above 60 transits/day before 1 Jan 2027: ~18%; before 1 Jul 2027: ~48%.
In plain terms: traders see a deal this year as possible but unlikely, and a real return to normal traffic as roughly even odds by mid-2027.
What has to happen before ships return
- A signed US-Iran deal that settles the US naval blockade, oil sanctions and Iran’s demand for transit “service fees”. The US insists the strait stays permanently toll-free.
- Attacks stop. Insurers will not return while tankers and bulkers are still being struck.
- Mine clearance is verified. US officials say more than 100 suspected mines were found and dealt with, but Iran has been accused of laying more.
- Insurance comes back. Even after a deal, the Lloyd’s Joint War Committee listing, war-risk premiums and P&I cover would take months to normalise.
- The backlog clears. Hundreds of vessels are stranded inside the Gulf and need to get out before new traffic flows normally.
Signals to watch
- A formal US reply to Iran’s proposal delivered through Qatar or Oman.
- A week without a reported attack on shipping.
- Daily transits climbing above ~40 (half of normal) and staying there.
- Any easing of the Joint War Committee listing or P&I clubs restoring cover.
- Qatar lifting LNG force majeure.
FAQ
When will the Strait of Hormuz reopen?
There is no agreed reopening date. As of 29 September 2026 (Day 212 of the closure), Iran has offered a seven-day roadmap to reopen the strait in exchange for the US lifting its naval blockade and oil sanctions, but President Trump publicly rejected it on 26 September. Prediction markets price roughly a 1-in-5 chance that traffic returns to normal before the end of 2026.
Is the Strait of Hormuz open right now?
No. Around 15-25 vessels a day are transiting against a pre-crisis norm of about 88, most with AIS transponders switched off. The waterway is not physically sealed, but war-risk insurance and continuing attacks keep normal commercial traffic out.
What would it take to reopen the Strait of Hormuz?
A US-Iran agreement covering the US naval blockade of Iranian ports, oil sanctions and Iran’s claimed transit fees; a halt to attacks on shipping; confirmed mine clearance; and then a gradual return of insurance cover. Even after a deal, insurers and shipowners have said normalisation would take months.
How long has the Strait of Hormuz been closed?
The closure began on 28 February 2026, when the IRGC warned ships that no passage would be permitted following US and Israeli strikes on Iran. 29 September 2026 is Day 212.
