The Strait of Hormuz crisis moved into a sharper phase over the last 24 hours as vessel counts, sanctions pressure and live security incidents all worsened at the same time. Only two tankers were tracked through Hormuz on Monday, a three-month low and far below the pre-war energy flow that made the strait the world’s most important oil chokepoint. The commercial risk became more immediate when an oil tanker was struck near Oman at the entrance to Hormuz, damaging its engine room and disabling the vessel. At the same time, Iran vowed retaliation after the U.S. widened sanctions and warned economic partners away from Tehran, while Iran’s own blacklist of tankers and threats around ship-to-ship transfers added another compliance layer.
Ship Universe Hormuz Watch
Operator Impact Snapshot
Hormuz traffic, tanker security and sanctions risk all deteriorated in the same 24-hour window.
Transit count collapse
Only two tankers were tracked through Hormuz on Monday, the lowest commodity-vessel tally since early May.
Tanker disabled near Oman
An oil tanker was hit near Ash Shishah, Oman, damaging the engine room and leaving the vessel disabled close to the Hormuz entrance.
Oil flow far below normal
Vortexa put Monday oil transits near 5 million bpd, far below the roughly 20 million bpd oil flow seen through Hormuz in 2024.
Sanctions risk widens
The U.S. widened Iran-linked sanctions exposure across shipping and other sectors, while Iran vowed retaliation.
Blacklisted tanker pressure
Iran’s 45-tanker blacklist and threats around ship-to-ship transfers add another layer for chartering, compliance and insurance screening.
Red Sea pressure overlaps
A separate tanker strike west of Yanbu shows the regional risk is not limited to Hormuz alone.

The latest data shows a chokepoint operating far below normal commercial capacity.
Lowest daily commodity-vessel tally since early May, according to reported ship-tracking data.
Vortexa’s provisional figure for oil moving through Hormuz on Monday.
Reported by August 23, still far below normal pre-war flow.
Approximate 2024 average oil flow through Hormuz, equal to about one-fifth of global petroleum liquids consumption.
| Issue | Latest Detail | Commercial Signal | Buyer or Operator Effect | Pressure Meter |
|---|---|---|---|---|
| Hormuz Transit CountCommodity-vessel flow | Only two tankers were tracked through the strait Monday, both entering the Gulf. | The visible flow is far below normal and too thin for Gulf exports to look commercially stable. | Owners, charterers and refiners face reduced fixture confidence and higher voyage-risk checks. | Severe |
| Oil Transit VolumeEnergy supply signal | Vortexa put Monday oil transits near 5 million bpd, with a seven-day average near 6 million to 7 million bpd. | The market has flow, but not enough to resemble normal Gulf export capacity. | Energy buyers need to price alternative crude, refinery slate changes, inventory draw and freight premiums. | High |
| Ash Shishah Tanker StrikeEntrance to Hormuz | A tanker was struck by an unknown projectile about 9 nautical miles northeast of Ash Shishah, Oman, damaging the engine room and disabling the ship. | The incident turns route risk into a direct hull, machinery, salvage and crew-safety concern. | Insurers and charterers may tighten security clauses, routing approvals, escalation triggers and notice requirements. | Severe |
| U.S. Sanctions ExpansionShipping sector included | Washington sanctioned nearly 60 Iran-linked targets and widened secondary-sanctions exposure across sectors including shipping. | Shipping, bunkering, finance, insurance, ports, commodity trading and vessel management all face higher screening burdens. | Counterparty checks, ownership history, STS links, AIS gaps and sanctions warranties become more central to fixtures. | High |
| Iran Retaliation ThreatGeopolitical response | Iran vowed retaliation after the expanded U.S. sanctions campaign. | The risk is not only more sanctions, but a feedback loop between economic pressure and maritime pressure. | Gulf exporters, LNG buyers and tanker operators need plans for sudden rule changes, detentions or route interruption. | High |
| 45-Tanker BlacklistIran transit enforcement | Iran warned that vessels dealing with blacklisted tankers, including through ship-to-ship transfers, could face action. | The blacklist increases legal and operational uncertainty around STS cargo chains and vessel history. | Cargo buyers may require deeper vessel-history review before accepting Gulf-linked barrels. | High |
| Bab el-Mandeb ComparisonRegional chokepoint context | Kpler counted 29 vessels through Bab el-Mandeb Monday, broadly in line with its 10-day average. | The Red Sea chokepoint is not showing the same transit collapse as Hormuz in the latest count. | The region still carries stacked risks, especially after the separate tanker strike west of Yanbu. | Medium High |
| Yanbu Red Sea StrikeSaudi export-route risk | A tanker was struck about 63 nautical miles west of Yanbu, with reports identifying a Saudi VLCC as the affected vessel. | The northern Red Sea is becoming part of the same energy-shipping risk conversation. | Bypass routes only help if alternative corridors remain safe, insurable and commercially predictable. | High |
Hormuz Transit Risk and Cost Tool
Estimate the voyage impact of low transit counts, war-risk premiums, security costs, delay exposure and sanctions screening.
War-Risk Premium
$1.4M
Modeled additional war-risk premium using the selected vessel value.
Delay Exposure
$510,000
Estimated waiting, rerouting, inspection or schedule-recovery cost.
Total Added Voyage Cost
$2.1M
War-risk premium plus security, routing and modeled delay exposure.
Risk-Adjusted Exposure
$23.5M
Planning exposure based on asset value, cargo value, route pressure and sanctions complexity.
Voyage Signal
The model shows severe exposure. Transit scarcity, live attack risk, insurance cost and sanctions complexity justify senior-level approval before fixture or voyage commitment.
