Hormuz Splits Into Three Shipping Systems as Visible Traffic Stays Near Standstill
🔔 Subscribe to ShipUniverse Weekly →
Shipping through the Strait of Hormuz remains far from normal despite large volumes of Gulf oil continuing to reach world markets through military-protected, AIS-dark and ship-to-ship routes. The latest preliminary Kpler data available on September 24 showed only three visible commodity vessels crossing on Tuesday, September 22, all outbound, versus four Monday and a 10-day moving average of about 15. At the same time, the ballast LNG carrier Al Mafyar reappeared inside the strait, suggesting limited gas-carrier movement has not stopped completely. Security conditions have worsened after the crude tanker LR Stephanie and LPG carrier Al Maryah were struck in separate incidents, while Saudi Arabia has partially restarted its East-West Pipeline and Iran has proposed reopening Hormuz within a week if the United States eases military pressure and its blockade. U.S. Central Command, meanwhile, says its forces have supported more than 2,000 commercial transits and more than 1 billion barrels of Gulf crude through Hormuz in recent months, illustrating how visible AIS counts now capture only part of the traffic picture.
The Strait Is Operating on Three Different Levels
Public AIS traffic is extremely low, protected and dark tanker movements continue behind that visible layer, and an increasingly important offshore transfer network is moving Gulf cargoes into ships positioned outside the strait.
This is the activity most commercial ship-tracking screens show. It has remained in the single digits on many recent days and captures only vessels broadcasting usable AIS positions.
Tankers continue moving with AIS disabled or restricted while military-protected transits carry oil, gas and other cargoes through the same physical chokepoint.
Shuttle tankers cross Hormuz, discharge to receiving vessels outside the Gulf, then return. Kpler says regional STS support capacity is approaching practical limits.
Seven Signals Moving the Strait Right Now
Hormuz is simultaneously seeing lower visible traffic, active tanker attacks, continued LNG experimentation, partial Saudi rerouting, record pressure on offshore transfer logistics and an unresolved diplomatic negotiation over reopening the waterway.
| Current Signal | Latest Reading | What Changed | Shipping Impact | Critical Detail | Next Confirmation Point |
|---|---|---|---|---|---|
| Visible Hormuz Traffic | SEVERELY DEPRESSED 3 Ships Tuesday | Preliminary Kpler data fell from four visible commodity-vessel crossings Monday to three Tuesday. | Owners continue to avoid routine visible transit patterns, leaving public AIS traffic at a fraction of normal levels. | All three Tuesday vessels were outbound. One was a Panamax tanker. | A sustained increase above the approximately 15-vessel 10-day moving average would be the first stronger traffic-normalization signal. |
| Tanker Security | TWO RECENT STRIKES LR Stephanie + Al Maryah | A crude tanker and LPG carrier were struck in separate incidents within roughly 24 hours. | The incidents increase direct voyage risk for owners already requiring elevated premiums, escorts or operational restrictions. | LR Stephanie sustained two minor crew injuries. Both vessels continued without towing. Responsibility has not been publicly established. | Further attacks on escorted or compliant vessels would materially affect assumptions about which ships can transit safely. |
| LNG Movement | LIMITED RETURN Al Mafyar Reappears | The ballast LNG carrier was detected inside Hormuz Tuesday after previously being outside the strait. | LNG movement remains exceptionally important because Qatar cannot economically bypass Hormuz with its existing export system. | QatarEnergy says the crisis could delay later North Field East expansion trains and that damaged Ras Laffan capacity will take years to fully repair. | Multiple loaded Qatar-linked LNG carriers exiting consecutively would indicate a more meaningful shipping recovery. |
| Saudi Hormuz Dependence | PARTIAL RELIEF East-West Restarted | Saudi Arabia restarted its cross-country pipeline at a reduced rate and is preparing renewed Yanbu crude exports. | Every barrel successfully restored through Yanbu can reduce incremental Saudi tanker exposure to Hormuz. | Aramco is reportedly targeting throughput toward 4M b/d, but full 7M-b/d system capacity is not yet restored. | Repeated VLCC loadings at Yanbu will show whether the bypass is materially reducing Gulf tanker demand. |
| Gulf of Oman STS Network | CAPACITY PRESSURE Fujairah + Sohar | Gulf exports increasingly rely on shuttle tankers that cross Hormuz and transfer oil offshore to long-haul vessels. | The same barrel can require additional vessel time, two tankers and offshore transfer infrastructure. | Kpler says support infrastructure at Fujairah and Sohar is at or close to practical limits. | Additional lightering off India or Malaysia would indicate the existing Gulf of Oman system has reached its effective ceiling. |
| Reopening Proposal | NEGOTIATIONS OPEN Iran: Within 1 Week | An Iranian official said Tehran could reopen the strait within a week if the U.S. reduces military pressure and lifts its blockade of Iranian ports. | A negotiated reopening could change vessel availability and insurance conditions much faster than infrastructure changes alone. | The United States and Iran remained divided on September 24, although both sides continued diplomatic contacts around the UN General Assembly. | Any written agreement covering transit guarantees, blockade terms, mines and vessel protection would be materially stronger than public statements. |
| Oil Market | RISK PREMIUM ACTIVE Brent Above $100 | Brent moved back above $100 as traders assessed limited progress in U.S.-Iran diplomacy. | Freight, insurance and physical crude availability remain tied directly to changes in Hormuz security. | Reuters reported Brent around $103-$105 during September 24 trading as negotiations remained unresolved. | Oil prices will continue reacting to physical shipping data, Saudi bypass recovery and any U.S.-Iran security agreement. |
