#Gate广场万圣节 #WCTCS9 Two supply lines, two gauges: the Hormuz sea lane and the Mongolian coal road

Two headlines landed in the same update: oil moving through the Strait of Hormuz fell to about 2.9 million barrels a day, and coal trucks from Mongolia to China are set to resume above 1,100 vehicles a day. They look unrelated, but both are gauges on the same dashboard: how freely energy reaches the people who burn it. I read each needle, checked what could make it mislead, and marked what moves it next.

Gauge one: the sea lane

What the needle says. The 2.9 million barrel figure comes from Financial Times calculations for the single most disrupted day, not from a weekly average. That matters. Kpler put the daily average for the week to October 13 at 11.62 million barrels, down from a baseline of 17.15 million. By my math, the 2.9 million day is about 17% of that baseline, while the weekly average is about 32% below it. A separate seven-day measure shows flows about 43% below pre-conflict levels. Before the war, roughly 20 million barrels a day passed through the strait in 2024.

Why the needle can mislead. Estimates disagree widely. Kpler's own estimate cited by Reuters was 8.5 million barrels a day, while the Journal's figure for the same period was 14 million. And a bad day is not a bad month: the IEA said total flows through Hormuz rose by 3.7 million barrels a day to 10.9 million in September, with bypass pipeline exports up to 5.6 million. The real story is a recovery that keeps being interrupted.

Why the interruption matters. Lloyd's List counted 28 attacks on ships in October, its highest monthly total since the war began, and the issue is shipping and insurance as much as lost barrels.

What the price says. Brent settled on Thursday at its highest since May 4 and traded near $113.75 on Friday. The physical market is tighter than the screen: on October 13, the Brent spot price was $125.78 while futures closed at $105.69, a gap of about $20, or 19% of the futures price by my arithmetic. Buyers of actual cargoes are paying that premium.

What the forecasters expect. The EIA sees Brent averaging $105 in the fourth quarter and $84 next year. Morgan Stanley also sees about $105 through year-end, notes that U.S. distillate stocks sit 12% below average, and says LNG through Hormuz may not recover until April 2027. For reference, Brent averaged $114 in September and reached $131 on September 15.

Gauge two: the coal road

What the needle says. Coal trucks from Mongolia to China are set to resume above 1,100 vehicles a day. The context comes from the border. Mongolian Mining reported that coal-loaded trucks crossing into Ganqimaodu averaged 897 per operating day in Q3, down 34% from 1,366 in the prior quarter, though the year-to-date average of 1,177 remained 15% above the 2025 full-year average of 1,023. By my math, 1,100 trucks would be about 23% above the Q3 average, about 7% below the year-to-date average, and about 7.5% above the 2025 average. So the resumption means a return to normal, not a surge.

Why it matters. China imported 60.07 million tonnes of Mongolian coking coal in 2025, 51% of its metallurgical coal imports, and Mongolian coal is cheaper to mine than Shanxi's, by about 50 to 150 yuan a tonne. The weak quarter had a cause: coking coal prices in China rebounded strongly in Q3, driven mainly by constrained supply from domestic producers.

What changed at the border. Mongolia's cabinet on October 8 ordered officials to ease congestion at six junctions around the Gashuunsukhait crossing, viewed as the main bottleneck for coking coal entering China. A resumption above 1,100 trucks fits that fix.

What it means for futures. More arrivals mean more supply for coking coal and coke, which is a mildly bearish factor for prices, all else equal. Two things offset that: domestic Chinese supply is still constrained, and an energy shock tends to lift coal demand as a substitute fuel. That last link is my inference, not a figure from the sources.

How the two gauges connect

My reading is that the sea lane and the road are mirror images. When oil and LNG flows are uncertain, Asian buyers lean harder on land-based and domestic fuels, which makes the Mongolian border more valuable. If Hormuz stays disrupted, coal logistics become a quiet hedge. If Hormuz normalizes, the premium on both fades.

The macro tie

Energy prices feed inflation, and the Fed decides on October 28. A sustained oil spike makes the central bank's job harder, which is why a shipping story belongs in a markets dashboard.

1. Daily Hormuz transits against the 17.15 million barrel baseline.
2. The gap between Brent spot and futures, which signals physical tightness.
3. Truck counts at Ganqimaodu, and whether they hold above 1,100 on a weekly average.
4. Coking coal and coke futures for the first sign of supply relief.
5. Attack counts, since insurance costs move before barrels do.

Normalizing: attacks ease, flows return toward 11 million barrels or more, Brent drifts toward the EIA's $105, and coal trucks settle near the year-to-date average.
Stalemate: flows stay choppy, Brent holds above $100, and coal prices stay firm on domestic constraints.
Escalation: more attacks push Brent toward the September peak near $131, and the coal road becomes a bigger pressure valve.
Commodity markets look like they trade barrels and tonnes, but most of the time they trade the path between producer and buyer. The numbers to trust are the ones that measure that path, and the best habit is to read the average before the headline. #OilMarket @Gate_Square
