Hormuz Shipping Remains Severely Constrained as Costly Tanker-Shuttle System Takes Over
🔔 Subscribe to ShipUniverse Weekly →
Commercial shipping through the Strait of Hormuz remains heavily constrained even as Gulf oil exports recover through an increasingly elaborate tanker-shuttle network. Updated Kpler data showed 17 trackable commodity vessels crossing Hormuz over the September 19-20 weekend, down from 37 the previous weekend, while many oil movements continue with transponders switched off. At the same time, crude exports cleared through Hormuz are running at about 6.5 million barrels per day in September, their highest sustained level since the brief June ceasefire. Roughly 2.5 million b/d is expected to be transferred ship-to-ship in the Gulf of Oman this month, up from 1.4 million b/d in August and equivalent to about 40% of current Hormuz oil flows. Shuttle tankers load inside the Gulf, cross the strait, transfer cargo near Fujairah or Sohar and then cycle back while receiving tankers continue toward buyers, predominantly in Asia. The workaround has kept barrels moving but at exceptional cost: Middle East Gulf-to-China VLCC freight has recently been quoted around or above $30 per barrel, compared with roughly $20 for cargoes loading outside Hormuz in the Gulf of Oman.
Hormuz's New Floating Oil-Export System
Oil exports are recovering faster than visible commercial traffic because a growing fleet of shuttle tankers is moving Gulf crude across the strait to offshore transfer hubs outside the highest-risk zone.
Updated Kpler data for September 19-20 showed trackable commodity-vessel traffic falling more than 50% week on week.
Highest sustained level since the brief June ceasefire, according to Kpler data cited by Reuters.
Gulf of Oman ship-to-ship crude transfers are up from approximately 1.4M b/d in August.
Current long-haul freight consumes more than one-quarter of a roughly $105 barrel of crude.
Kpler says both major transfer locations are believed to be operating at or close to capacity.
Hormuz Shuttle-System Operating Board
The bottleneck is shifting from simply finding tankers willing to cross Hormuz toward having enough ships, transfer slots and offshore infrastructure to sustain a multi-stage export chain.
| Pressure Point | Current Reading | Operating Model | Physical Constraint | Commercial Effect | Latest Evidence |
|---|---|---|---|---|---|
| Strait Traffic | SEVERELY REDUCED 17 Weekend Transits | Visible commercial traffic remains a fraction of historical activity while substantial oil movements occur with limited AIS visibility. | Security risk, owner willingness, naval-protection availability and Iranian restrictions continue to limit normal passage. | Charterers cannot treat a normal Gulf loading as a routine direct voyage with predictable vessel availability and transit timing. | Updated Kpler data showed 17 trackable commodity vessels on September 19-20 versus 37 a week earlier. |
| Offshore Shuttle Network | EXPANDING 2.5M b/d | Gulf-loaded shuttle tankers cross Hormuz, discharge by STS outside the Gulf and return to repeat the cycle. | Every barrel requires additional vessel time, transfer equipment, anchorage capacity and coordination compared with a conventional direct voyage. | More ships are consumed per delivered barrel, tightening available tanker supply globally. | Kpler expects Gulf of Oman STS crude loading to rise from 1.4M b/d in August to roughly 2.5M b/d in September. |
| Fujairah & Sohar | CAPACITY PRESSURE Primary STS Hubs | Tankers rendezvous offshore and transfer crude ship-to-ship before receiving vessels begin longer international voyages. | Kpler says both locations are believed to be operating at or close to capacity. | Additional shuttle growth may require direct Gulf-to-Asia voyages or less efficient STS zones. | Kpler identifies offshore West Coast India and Malaysia as possible alternatives if transfer demand exceeds Fujairah/Sohar capacity. |
| VLCC Freight | RECORD ECONOMICS ~$30+/bbl | Owners willing to enter the Gulf are charging large premiums for vessel exposure, delay risk and scarce tonnage. | Vessel supply is increasingly absorbed by repeated shuttle voyages and longer rerouted trades. | Freight can represent more than one-quarter of crude value, versus low-single-digit percentages before the war. | Kpler recently placed MEG-China freight around $30/bbl versus about $20/bbl for Gulf of Oman loading; Reuters/LSEG subsequently reported levels above $30. |
| Saudi Export Shift | RISING HORMUZ USE 42M bbl / Week | Saudi barrels previously moved west through the East-West pipeline are increasingly loading at Gulf terminals and exiting through Hormuz. | Damage to the pipeline and reduced Yanbu activity have weakened Saudi Arabia's principal Hormuz bypass. | More Saudi barrels compete for shuttle capacity already used by UAE, Iraqi and other Gulf exports. | Kpler counted 22 tankers carrying 42M barrels out through Hormuz during the week of September 13. Saudi Arabia and Iraq each represented 43% of the volume. |
| Pinios → New Constant | LIVE EXAMPLE 2M bbl | Pinios carried Iraqi Basrah crude through Hormuz and transferred the cargo off Fujairah. | Requires two VLCCs and an offshore transfer operation rather than one conventional direct loaded voyage. | The receiving tanker, New Constant, can proceed toward China without needing to make the high-risk Gulf transit. | Kpler and LSEG data showed the transfer underway on September 21. |
| LNG Passage | LIMITED MOVEMENT Ras Laffan → Pakistan | Some LNG carriers continue to transit despite depressed overall traffic. | LNG shipping has fewer immediate replacement loading points than crude and remains heavily dependent on Gulf export infrastructure. | Reduced vessel access can affect Qatar-linked cargo scheduling and regional gas availability. | Shandong Redwood exited Hormuz on September 19 with LNG loaded at Qatar's Ras Laffan and was heading toward Pakistan. |
