Hormuz Watch — 2026-08-19

Bottom line

Strait of Hormuz remains effectively closed to routine commercial traffic ~6 months into the US-Iran War. June MoU is dead, talks stalled, both sides dug in. Traffic at ~17% of pre-conflict baseline over the past week. Oil stockpiles drawing down globally; insurance costs remain punitive.

Strait status & traffic

Traffic past 7 days: ~17% of pre-conflict average (baseline ~88–130 transits/day; late-July prints as low as ~10/day).
Iran re-declared the strait closed after accusing Washington of violating the June MoU; US reinstated its naval blockade of Iranian ports.
Southern Omani Route (temporary corridor) remains highest-risk: 16 of 18 projectile strikes reported by UKMTO since Jul 6.

Naval / military

Carrier group en route to CENTCOM to replace USS Abraham Lincoln (Aug 14); Lincoln crew past recommended deployment length — morale/readiness strain flagged.
IRGC high-speed craft activity logged 7 of past 8 days near the strait.
Aug 18: Liberia-flagged product tanker AMARA showed sharp course deviation ~5 nm SE of Qeshm Island — watching for confirmation of interference or attack.

Incidents & insurance

56 vessel-damage reports in/near the strait since war began Feb 28.
Late-July cluster still shaping risk pricing: tanker struck 11 nm NE of Lima (Oman), close-proximity explosion 21 nm NE of Khasab, GasLog Shanghai (LNG) damaged on departure; third ADNOC tanker hit in under a week — UAE publicly blames IRGC “piracy.”
War risk: 3–10% of hull value vs ~0.25% pre-war (a $100 Mt ank er n o w$ 3–10M per transit); some insurers dropping Gulf war-risk cover entirely.
SCFI 3,205.97 (Jul 31, +4.67%), first rise after three weeks of declines.

Oil / energy supply chain

Hormuz crude+liquids flows: ~4.9M b/d in Q2 vs 21.6M b/d in Q4-25. Production shut-ins ~5.5M b/d (July).
Brent peaked ~ $105 (J u l 23); f u t u res f l a tt hi s w ee k o n s t a ll e d t a l k s . [[E I A]] sees$ 78 by Q4-26 if traffic recovers — that’s the swing variable.
IEA 400M+ bbl emergency release drawing down; CNN (Aug 13): world burning through stockpiles with no resupply path at scale.
Saudi Arabia rerouting via East-West Pipeline to Yanbu (Red Sea) — partial mitigation only.

Diplomacy

US-Iran talks stalled; Oman-brokered channel (with Qatar/Pakistan MoU framework) not revived since July collapse.
Iran’s new national security chief Mohsen Rezaie: no full reopening without unfreezing Iranian assets + end to Israel’s wars in Lebanon and Gaza.
Trump continues to claim US “controls” the strait (Aug 12); Tehran counters it can “prolong” the war.
Jared Kushner met regional leaders Aug 16 — watch for a back-channel reopening attempt.

Watch next 48–72h

AMARA incident confirmation (Qeshm) — first indicator of a new interdiction wave.
Carrier handover window — transition periods historically correlate with IRGC probing.
Any Oman-channel restart signal following Kushner’s regional tour.
Insurance market: further cover withdrawals would choke even the residual ~17% traffic.
