Iran declares strait 'completely open'; contradicted same day

2026-04-17 · diplomatic · major

Foreign Minister Abbas Araghchi declared passage through the Strait of Hormuz completely open for all commercial vessels after a US-mediated Israel-Lebanon ceasefire, but Parliamentary Speaker Ghalibaf contradicted him the same day, saying the strait would not remain open while the US blockade continued. Only a handful of vessels transited in the following days.

Brent next close -15.4% · +7 days -4.1% · transits 5.7 → 5.9 per day · outsized reaction — bigger than 99.5% of pre-crisis days

Attribution caveat: 2 other major event(s) sit inside this one's ±7-day window (2026-04-12 Islamabad Talks collapse; US announces blockade of Iranian ports; 2026-04-18 Iran re-closes Strait of Hormuz, fires on merchant ships), so the reaction is not cleanly separable.
