Hormuz Watch — 2026-08-17

BLUF: The 60-day Islamabad MOU expires today with no extension, no talks, and no deal — and the strait answered by going to zero. Kpler logged five commodity transits Saturday and none Sunday, against 31 the prior weekend. That is the lowest weekend print of the crisis. The ADNOC strike cluster (three vessels last week, 23 cumulative) did what 170 days of blockade could not: it stopped the shuttle traffic cold, at least for a weekend. Meanwhile Bloomberg confirms the thing that has actually been holding oil under $90— * * d a r k s h u ttl e t r an s i t sr u nnin g ab o v e 4 mb / d * *, w i t h 150 s hi p s n o w f l o a t in g o ff O man f or STSt r an s f er . [[B re n t]] * *$ 89.28**, WTI $81.74, both roughly flat after a +5% week.

Chokepoint Status

Kpler weekend count: 5 transits Sat, 0 Sun — vs 31 the previous weekend. Pre-war baseline >130/day. Reuters characterizes it as a “near standstill.”
Saturday’s five included an empty VLCC running AIS-dark, an Indian-flagged VLGC that took the Iranian (northern) route, and a small tanker outbound with Iranian fuel oil. The composition matters more than the count: what still moves is either dark, Iranian-routed, or Iranian-cargoed.
Overall traffic down ~90% since Feb 28. Northern-route skew from Thursday’s UKMTO data (≈3:1 vs the Omani corridor) is now compounded by outright abstention.
Bab el-Mandeb: 49 weekend commodity transits, down from 55. No tracked Saudi oil shipments — the Houthi blockade declared Jul 20 is holding on the Red Sea flank.

The Dark Trade — what’s really keeping prices down

Bloomberg (Aug 16), sourced to people with direct knowledge: covert Hormuz shuttling is “running at full tilt” despite the attacks, at volumes above the 4 mb/d market consensus. Barrels from UAE, Iraq, Qatar and Kuwait are all moving this way.
~150 vessels now floating off Oman awaiting STS transfer, per EU Sentinel-1 imagery — vs ~40 in January.
Saudi Arabia is entering the trade. Two ships loaded at Ras Tanura last week; Bahri has 16 VLCCs positioned off Oman with three more inbound — 38 million barrels of collective capacity. Riyadh is hedging its Red Sea route against the Houthis by returning to the Gulf.
ADNOC has sold ~135 million barrels and issued another sales round last week. Statement: “Despite the repeated targeting of our vessels, we are determined to continue meeting our responsibility.”
Read: this is the single most important analytic correction available right now. The market is not pricing a closed strait — it is pricing a half-open, unlit, uninsurable one. Energy Secretary Chris Wright’s 9 mb/d claim and the “1 ship transited” headlines are both true because they measure different things. The dark fleet is the actual clearing mechanism, and the strikes on ADNOC hulls are an attack on it specifically. If Iran degrades the shuttle, the $80–90 band goes.

Diplomacy — the MOU dies

The 14-point Islamabad MOU, signed Jun 17, expires today. Neither side sought an extension. Iran’s position, via a senior source to Reuters: Tehran does not consider the 60-day clock to have started, so there was nothing to extend.
Donald Trump (New York, Fri): “There’s nobody to negotiate with.” Told Americans to accept paying “a little bit more” for fuel; repeated the “wall of steel” line and the Hormuz-as-US-territory claim.
Kazem Gharibabadi on X: the strait “was Iran’s, is Iran’s, and will remain Iran’s.”
Abbas Araghchi (Sat): Washington must meet Iran’s conditions before shipping resumes. No decision to resume talks.
Mohammad Bagher Ghalibaf: the strait “will not return to prewar conditions”; Iran will charge transit/service fees now that the toll-free window under the MOU has lapsed. No fee schedule, timeline, or vessel scope has been published.
Analyst Nader Itayim: “Why are we still hanging on to this 17 August date like it means something? The MOU died weeks ago.”
Conflicting report to flag: Middle East Monitor (Aug 12) reported a US-Iran agreement to extend the ceasefire. Not corroborated by Reuters, The National, or CNBC as of this morning. Treat as false until sourced.
Read: the expiry itself is theater — the agreement stopped functioning in early July. What is not theater is Ghalibaf’s toll regime now having a legal predicate in Tehran’s telling. A published fee schedule would be the first concrete Iranian move to convert de facto control into a revenue institution. Watch for it this week.

Naval / Military Ops

US maintains the blockade of Iranian ports and says it can do so indefinitely. ~20+ warships enforcing; CENTCOM running total was 59 vessels redirected / 3 disabled / 2 boarded as of Aug 13.
Bloomberg’s sources note more incidents than are publicly acknowledged — both attacks on merchant ships and defensive Western engagements against vessels harassing freighters. The public incident record understates the tempo in both directions.
Escorted convoys continue under Operation Project Freedom (launched May 4), but the weekend data suggests escort availability is not the binding constraint — owner and underwriter willingness is.

Attacks on Shipping

ADNOC cumulative: 23 vessels attacked since the conflict began — 1 fatality, 20 crew injuries. Three struck last week (Thu ×2, Fri ×1). Note: this supersedes the “17 vessels” figure carried in prior digests; ADNOC’s own count is higher.
Sat Aug 15 UKMTO report of a projectile striking a bulk carrier hull remains unresolved as separate incident vs. re-report.
IMO tally (Aug 11): 65 confirmed vessel incidents, 17 seafarer deaths.
Prior-week pattern holds: engine rooms primary damage location in 12 of 20 strikes since Jul 6; 16 of 18 landed in the US-coordinated southern (Omani) corridor.

Kharg Island western terminal reactivated Aug 12 after a 25-day halt — a VLCC berthed and loading for the first time since Jul 18. Eastern terminal and LPG facility remain idle; 16–17 tankers in the offshore waiting area. Iran is simultaneously expanding the Caspian corridor (Russia→Iran wet-cargo shipments up 2.9× over 164 days).

Insurers report a steady stream of new business requests from Gulf producers — the dark trade is being underwritten, not just tolerated. Heidmar CEO Pankaj Khanna: “It’s a dark trade. It’s the only option right now as not all owners are willing to take the risk.”
Read for underwriters: the risk pool is now adversely selected. The owners still transiting are the ones willing to run dark, which degrades claims investigability and salvage response simultaneously. Expect that to show up in machinery-damage and pollution-liability pricing before it shows up in hull rates.

Environmental / Secondary

Caroline Bezengi — sanctioned Russian shadow fleet tanker, ~800,000 bbl, aground since Jun 30 near an Omani marine reserve. Slick ~1,300 km²; oil ashore across up to 40 km of coastline at Ras Madrakah.
Ambrey salvage ongoing; specialists aboard stabilizing cargo, response vessels en route. Khareef monsoon conditions are the limiting factor.
New: a separate slick appeared in Gulf of Oman satellite imagery last week with no identifiable source vessel — a direct consequence of transponder-dark transiting. Expect more of these, and expect attribution to fail.

Watch Items

Does the toll schedule get published? Ghalibaf has the predicate now. A published Iranian fee regime is the crisis’s institutionalization point and the clearest signal that Tehran is planning for a long occupation of the status quo.
Does the weekend zero persist? One weekend is noise; a full week near zero means the dark shuttle itself has been deterred, and the $80–90 band breaks upward.
The Scott Bessent package. Promised “next week” as of Aug 14 — that is now. Scope test remains: secondary sanctions on Chinese teapot refiners and yuan-clearing banks = order-of-magnitude escalation. China takes ~90% of Iranian crude exports. Anything less is designations.
Saudi entry into the shuttle trade. 38M bbl of Bahri capacity staged off Oman. If Riyadh’s hulls start getting hit, the conflict’s political geometry changes.
ADNOC count discrepancy (17 → 23). Reconcile the company figure against UKMTO/IMO tallies; the gap suggests a meaningful volume of unreported incidents, consistent with Bloomberg’s sourcing.
Distillate cracks and Q4 European/Asian gas storage if closure runs past September.
