Hormuz Watch — 2026-08-21
Status
Strait of Hormuz remains effectively closed — ~6 months since Iran shut it on 28 Feb; re-closed since 12 Jul after the 17 Jun US–Iran MOU collapsed over route disputes. US naval blockade of Iranian ports stays in force; Trump confirms no ongoing talks with Tehran.
Traffic
- 73 transits for the week of 10–16 Aug (down from 91 prior week) — vs a pre-crisis baseline of ~73 per day.
- 16 Aug recorded a single transit. Traffic suppressed by Tehran targeting Hormuz users and the US blockade of Iranian ports.
Incidents (last 72h)
- Tanker boarded by Iranian forces near Qeshm Island on 18 Aug now assessed seized, holding stationary off the Khasab approach, North Hormuz corridor.
- Third attack on an ADNOC-affiliated vessel in 48 hours; UAE blames Iran, calls it a “flagrant violation” of international law.
- One seafarer killed after a bulker was struck this week. Eight vessel attacks in the strait this month.
- IRGC claims hits on two tankers transiting under US military escort, four more turned back — unconfirmed by Western maritime authorities.
Naval / Escort Posture
- US escort plan in limbo: Energy Secretary says US “not yet ready” to escort tankers; IMO head warns escorts won’t guarantee transits.
- IRGC claims (above) suggest escorted convoys are being contested directly — escalation vector to watch.
Energy Markets
- Brent broke above 82.13 earlier this month.
- ~13M bpd of crude (one-fifth of global consumption) normally moves through Hormuz.
- IEA warns global oil stockpiles are drawing down fast — reopening pressure building.
Supply Chain & Insurance
- Bypass math doesn’t close: Saudi East-West Pipeline + UAE Fujairah terminal = 3.5–5.5M bpd capacity vs ~20M bpd normal Hormuz flows → 14.5–16.5M bpd shortfall.
- Qatar LNG still offline since the 18 Mar strike on Ras Laffan; Asia relies on the strait for 27% of LNG imports.
- War-risk cover being withdrawn or repriced at multiples; Gulf offshore platforms effectively uninsurable at standard terms; premiums +50% or more.
Watch Items
- Fate of the seized Qeshm/Khasab tanker and crew — precedent for further seizures.
- Whether US commits to formal convoy escorts — IRGC contact with escorted vessels is the sharpest escalation risk.
- Stockpile drawdown pace vs. any back-channel reopening talks (none confirmed).
- ADNOC/UAE response after third attack — Fujairah loadings and UAE posture shift.
