Iran Threatens “Forceful Response” in Strait of Hormuz, Polymarket Yes Odds Slide to 25.5%
Iran’s military command warned ships against using unapproved routes in the Strait of Hormuz, threatening an “immediate and forceful response” for noncompliance. The warning coincided with a sharp drop in Polymarket odds for “Strait of Hormuz traffic returns to normal by July 31?” to 25.5% from 42.0%.
Key Takeaways
- Polymarket prices a 74.5% chance that Strait of Hormuz traffic will not return to normal by July 31 (Yes 25.5%, No 74.5%).
- Odds moved lower after Iran threatened a forceful response against vessels that use unapproved routes, raising uncertainty over shipping flows.
- The contract resolves on July 31, 2026, after the Yes price fell 16.5 percentage points from 42.0% to 25.5%.
Iran’s Khatam al-Anbiya Central Headquarters warned that ships transiting the Strait of Hormuz must follow designated routes and Iranian navigation protocols, saying violations would face an immediate and forceful response. The statement came a day after Qatari mediators said indirect talks between US and Iranian officials were making positive progress toward a peace deal. US Central Command said it hosted a security dialogue in Bahrain where regional leaders backed the free flow of commerce, a claim Iran’s deputy foreign minister Kazem Gharibabadi rejected while calling for an end to US intervention and withdrawal from the region. The strait carried about one-fifth of global oil and LNG trade before a late-February conflict began, and MarineTraffic has recorded at least 49 attacks on commercial vessels since February 28. Transits have risen since a June 17 memorandum of understanding signed by US President Donald Trump and Iranian President Masoud Pezeshkian, but remain well below roughly 130 daily crossings seen before the conflict, with MarineTraffic data showing at least 45 vessels crossed on Wednesday, up from 34 on Tuesday.
