Strait of Hormuz traffic plunges 75%, exports severely constrained

Summary
Satellite/ship-tracking data show vessel traffic through the Strait of Hormuz down to ~36 ships/day from a pre-war 140–150, implying a major disruption to Gulf crude, products, and LNG flows. This signals acute supply risk and justifies a higher Middle East risk premium across oil, gas, tanker freight, and regional assets.
Details
-
What happened: Kpler data indicate that vessel traffic through the Strait of Hormuz has collapsed to about 36 ships per day, down roughly 75% from the pre-war baseline of 140–150 ships/day. The report does not specify the exact cause (direct attacks, insurance withdrawal, military exclusion zones, or de facto blockades), but the magnitude points to systemic disruption rather than temporary weather or scheduling noise.
-
Supply/demand impact: Roughly one-fifth of global oil consumption and a large share of seaborne LNG move through Hormuz. A 75% fall in transits, even if partly comprised of non-energy vessels, strongly implies double‑digit percentage constraints on near-term crude and condensate exports from Saudi Arabia (East), UAE, Kuwait, Qatar, and Iran, as well as Qatari LNG and some UAE LNG flows. Even if some cargoes are delayed rather than canceled, the immediate effect is a sharp tightening of prompt physical availability, higher spot differentials for Arabian Gulf grades, and wider backwardation.
If we assume that at least half of the missing traffic is crude/products/LNG, that could translate into several million barrels per day of disrupted or delayed flows on a short-term basis. Inventories can buffer demand for a time, but refiners in Asia (China, Japan, Korea, India) and Europe relying on Gulf supplies will face higher replacement costs and may bid up alternative Atlantic Basin barrels.
-
Affected assets and direction: Brent and WTI should see a significant upside impulse as the market prices in the risk of a de facto partial closure of the world’s most critical oil chokepoint. Dubai/Oman benchmarks and Middle East official selling price (OSP) differentials versus Brent are likely to spike. Qatari LNG-linked benchmarks (JKM) and European TTF should gain on fears of tighter global LNG availability. Tanker freight rates for VLCCs and LNG carriers will rise sharply, with war risk premia and insurance costs increasing.
-
Historical precedent: Episodes like the 1980s “Tanker War,” 2019–2020 Gulf tanker attacks, and occasional Iran–US tensions around Hormuz produced substantial but more modest traffic disruptions and still added several dollars per barrel to crude benchmarks. A documented 75% drop in traffic is more severe and could generate multi‑percentage price moves.
-
Duration: The duration depends on whether this is an acute security incident or a sustained conflict posture. The market will initially price this as a medium‑term risk (weeks to months) until there is clear evidence of normalization. The risk premium will remain elevated even if some traffic quickly resumes, as shippers and insurers will remain cautious.
AFFECTED ASSETS: Brent Crude, WTI Crude, Dubai Crude, Qatar LNG (JKM benchmark), TTF Natural Gas, VLCC freight rates, LNG carrier freight rates, Saudi riyal forwards, Qatari riyal forwards, GCC sovereign CDS
