Hormuz oil transits plunge; flows near standstill

Summary

New data show only seven vessels crossed the Strait of Hormuz Thursday, down from a 10‑day average of 15, with only two outbound and none carrying oil. This points to a sharp, ongoing disruption of seaborne crude and condensate flows from the Gulf, sustaining and likely increasing the war‑related risk premium in oil and LNG.

Details

Kpler data cited by Reuters indicate that traffic through the Strait of Hormuz has dropped to less than half of its recent 10‑day average, with just seven vessel crossings on Thursday versus a normal 15. Critically, only two ships were outbound and none were carrying oil, implying that crude exports from key Gulf producers are effectively being paused or sharply curtailed, at least on visible AIS‑tracked tonnage. The report also notes that additional vessels may be transiting with AIS turned off, but even allowing for some dark traffic, the visible collapse points to a very material disruption.

Roughly 17–18 million bpd of crude and condensate normally transit Hormuz in peacetime. Even a temporary 20–30% impairment in observable flows can remove several million bpd of supply from transparent markets, forcing refiners to draw down inventories, re‑route, or bid up alternative barrels (Atlantic Basin, West Africa, U.S. Gulf). With prior reports already highlighting war risk in the strait and attacks on regional infrastructure, this fresh datapoint confirms that the disruption is not just theoretical but is manifesting in physical flows.

The immediate impact is bullish for Brent and WTI, with an elevated risk premium on prompt spreads and front‑end time spreads likely to widen. Middle distillates (gasoil, jet) and fuel oil exposed to Gulf exports should also firm. LNG markets are affected indirectly: while Qatar can still ship some volumes, heightened maritime risk and insurance costs in Hormuz will support European and Asian hub prices and raise the value of U.S. and Atlantic Basin LNG.

Historically, Hormuz scare episodes (e.g., 2011–2012 rhetoric, 2019 tanker attacks) have added several dollars per barrel of risk premium when markets believed flows could be curtailed; in the current context of already‑tight balances and damaged Saudi infrastructure, the price response could be larger. If the flow reduction persists for days to weeks, expect a structurally higher floor for Brent and regional benchmarks, with volatility elevated. A quick diplomatic de‑escalation or evidence of normalizing tanker traffic could unwind part of the move, but for now the disruption appears ongoing rather than transient.
