Yanbu Runs Dry This Week, and Tehran Reaches for Article 102
BY THE HARBORMASTER · TANKERBRIEF DESK · ENERGY AND SHIPPING ANALYSIS
SITUATION UPDATE
Yanbu's tank cover runs out between Wednesday and Friday. Petroline has been dead since Sep. 11, when a drone strike destroyed a pumping station southeast of Madinah, and Goldman Sachs has widened the repair range at both ends, from "very soon" to eight weeks. Aramco has declared no force majeure and named no restart date. Goldman puts ~2M bpd of recent Yanbu liftings at risk, the terminal's throughput against the ~5M bpd this desk carries for the line, of which only ~1.0-1.3M bpd cleared northbound through Suez and SUMED.
Saudi Arabia is answering by going back through the Strait of Hormuz. Bloomberg reported Monday that the Kingdom raised shipments through the strait in the first ten days of September and is seeking to raise them further. On Sunday the Salalah ministerial was called off at Riyadh's request. Axios separately reported that Saudi Arabia had submitted amendments to the Omani-Iranian text because the language "could effectively establish a new status quo in the strait". No replacement date exists.
Tehran has stopped waiting for one. Iranian foreign ministry spokesman Esmail Baghaei said at his Monday press conference, in remarks carried by the Tehran Times, that the understanding between Iran and Oman, "as two littoral states, has been finalized", and that the two will decide "how to announce or register the understanding". Registration is the new word: lodgement with the UN Secretariat under Charter Article 102, which either party can do alone. Separately, the Panama-flagged tanker El Gaia is burning under tow, one Indian seafarer missing from fourteen. The IRGC Navy says she struck mines on a "forbidden" route and that the strait "remains under our smart control". CENTCOM calls that "FALSE": an Iranian missile disabled her last month, an Iranian drone struck her again this weekend off Oman.

ANALYSIS
Crude cannot hold a spike because the balance clears close to here. The IEA now forecasts 2026 demand to fall 2.5M bpd year on year, a cut of 940K bpd from its August number, while August production fell 1.6M bpd to 100.1M bpd. Demand is closing faster than supply is losing barrels, and with 0.22M bpd of cushion the clearing mechanism is price rationing. Watch the products and the long end. Back out the Sep. 14 US retail diesel average of $6.23/gal, a record, and the implied crack sits above $100/bbl against a pre-crisis norm nearer $15-25, which puts the binding constraint in refining. A 10-year above 5% in a supply shock is the wrong sign: textbook shocks push long yields down. The expression: crude capped and products bid, sell $109 spikes the prompt spread does not confirm, own the Yanbu print. Transit data threw up three prints from two trackers this week, and they reconcile: Kpler counts cargo-attributable vessels against a trailing mean, MarineTraffic counts every lit hull on a four-day slope. The shape is a trough, and direction cannot be resolved at 9-14 lit transits a day with more than 80% dark.
Riyadh's posture is more coherent than it looks. Taking the benefit of an arrangement while refusing it legal status defeats acquiescence: a state that ships but never signs preserves the argument that it acted under necessity, as Kuwait did when it reflagged in 1987. What is weak is the clock. The split holds only while the Kingdom has an alternative to the corridor, and with Petroline down, Jizan offline and Yanbu dry inside three days it is nearly out. Every Saudi cargo is also conduct, and a formal protest note is what stops a record becoming a regime. None has surfaced.
Article 102 registration confers no legal status. Under General Assembly Resolution 97(I) it implies no judgment on the nature of the instrument or the status of a party, and a bilateral text cannot bind a tanker whose flag state never signed. Its audience is the market: a dated document at a named body turns "Iran says" into an object war-risk underwriters and charterers can price, and pricing is what makes a corridor durable.
WHAT TO WATCH
- Which body Tehran names. UN lodgement is cheap and thin; an IMO routeing submission would be stronger and likelier to die in committee. The choice separates a legal move from a legitimacy move.
- Whether any GCC state or registry is reported to protest once anything is lodged. Absence of objection is how practice becomes regime.
- Yanbu loading data Wednesday to Friday. Silence past Friday confirms the arithmetic, and a confirmed stop is worth $4-8 on the day.
- Any new Salalah date. Absence past Friday marks the stall deliberate, not logistical.
- The next Saudi official selling price round, and EIA distillate inventories Wednesday alongside the Fed. Aramco sells Asia FOB, so a freight-compensating discount is the signal Riyadh is paying for its own reroute.
CORRECTION, ISSUED SEP. 15 AFTERNOON
Two figures in this brief have been superseded since publication and are corrected above.
Oman's Maritime Security Centre said Tuesday that an Omani naval vessel evacuated 23 crew from the El Gaia and that two remain missing, against a complement of ~25, of whom 14 were Indian nationals. This brief reported the Indian-national subset only, which was accurate as far as it went but understated the ship's losses. Cumulative seafarers dead or missing rises from at least 20 to at least 21. Oman also placed the attack ~103 nautical miles northeast of Musandam, at the Hormuz approaches, rather than inside the Gulf.
Two regional officials told the Associated Press that Petroline repairs could take three to five weeks, including at a major pumping facility, though one said the line may work partially during them. That estimate is tighter than the Goldman Sachs range this brief carried and it removes "very soon" as a live outcome. No branch of it restores full throughput before Yanbu tank cover exhausts Sep. 16-18.

A Kpler-sourced count of 4 vessels on Monday, carried by Reuters, could not be corroborated on a second search and is reported rather than adopted; preliminary counts of that kind backfill upward as dark voyages are attributed, so it reads as a floor. An undated 6-vessel figure was discarded, as were April reports of Petroline returning to full capacity, which have now resurfaced on September queries for three consecutive days.
