The Strait of Hormuz is the narrow waterway between Iran and Oman that carries close to a fifth of the world’s oil. This page tracks, live, whether ships are getting through. New here? Start here →

Shipping in the Strait of Hormuz is under fresh attack, disrupting transit, and the latest official PortWatch count is 4 vessels on October 18 at 5% of typical; Brent crude is trading at $114.09; crisis pressure at 88 (extreme) and the Escalation Forecast at 60 (high).

Non-tankers went dark at 28.9% under the same test, so read this as a floor on hulls we stopped receiving rather than a count of evasions. The tanker rate (57.9%) is running 2.0x the whole-box ambient rate (28.9%), but within the same waters, compared cell by cell, 135 tankers went dark against about 125 expected at the ambient rate there, so the excess is not distinguishable from ambient dropout.

Today’s read

On OCT 18, IMF PortWatch's most recent published day, commercial transit through the Strait reached 5% of the pre-crisis vessel count: 4 vessels against a typical 85 per day. War-risk insurance for tankers priced at 32.0× pre-crisis as of 7 Oct, our last trade-press read, with 6 P&I clubs having cancelled war cover for charterers and other non-mutual liability in March 2026 (buy-back cover has been offered since). Brent has moved -1.71% in the past twenty-four hours.

PortWatch counts AIS-broadcasting crossings only. Tankers crossing with transponders off are not counted, and trade press reports such crossings, so true flow runs higher than the figure above.

    Brent stood at $113.65, down 2.09% over 24 hours, as of 15:44 UTC; IMF PortWatch recorded 4 transits on October 18, against a pre-crisis baseline of 85 per day.

Situation

The Strait of Hormuz remains effectively closed to commercial traffic, with IMF PortWatch recording 4 transits on October 18 against a pre-crisis baseline of 85 per day. AL Circle, citing an unverified single source, reports that Iran is holding the strait closed as seven conditions stall negotiations between Iran and the United States; that framing aligns with parliament speaker Mohammad Bagher Ghalibaf's October 4 statement that the strait will not open until Iran's conditions, rooted in the June Islamabad Memorandum, are met. Al Jazeera reports that Tehran remains firm on its demands despite diplomatic urgency around the ongoing US-Israeli conflict. Separately, per Iranian state media, a tanker caught fire after hitting a naval mine east of the strait; no maritime authority has confirmed that claim, and it repeats a pattern of unconfirmed mine-strike reports that US Central Command has previously disputed. On the second front, Yemen's Houthis say they struck Saudi Arabia's Ras Tanura refinery with a ballistic missile, per gCaptain; Riyadh has not confirmed the claim. Brent stood at $113.65, down 2.09% over 24 hours, as of 15:44 UTC; WTI stood at $99.97. The feed indexed 17 headlines in the past 24 hours. As of 15:52 UTC, 143 AIS-visible vessels were holding position away from berth in the Strait of Hormuz and Gulf watch box, a count that leaves out ships within 25km of a working port. On the Hormuz Index, Crisis Pressure, the state composite, sits in the extreme band, with its value set by physical transit deviation alone; the Escalation Forecast sits in the high band, with the Brent-WTI forward spread as its top contributor.

Vessel mix

Vessels grouped by type. A Capesize bulker and a VLCC are not the same signal for an energy desk. 180 vessels anywhere in the Gulf tracking box moved between two position reports in the past hour; 4 of them are inside the strait window itself. A first sighting, or a fix over an hour old, counts as neither moving nor holding, so this isn't a ceiling.

Dark-tanker count

135

tankers  · last 24hof 233 screened▲ vs 7d baseline 99.8

Tankers that were broadcasting actively on inside the strait core area and have stopped transmitting for between 3 and 24 hours. The screen is tankers only, with 50 or more sightings, last positioned inside the core area: a narrower population than the 9,085 vessels of every type ever recorded in the wider bbox since monitoring began.

That is 135 of 233 tankers that met the screen. Non-tankers that met the same screen went dark at 28.9% on the identical test. The tanker rate (57.9%) is running 2.0x the whole-box ambient rate (28.9%), but within the same waters, compared cell by cell, 135 tankers went dark against about 125 expected at the ambient rate there, so the excess is not distinguishable from ambient dropout. Read the count as a floor on hulls we stopped receiving, not a verified evasion tally.

Baseline averages the count over the last 168 hourly samples.

Container carriers.

Carriers

The nine largest container carriers by global TEU capacity, with their declared posture for Strait of Hormuz transit and any dollar figure a carrier notice states, per container or per TEU as the carrier quotes it. The surcharge and stranded-vessel figures are indicative editorial estimates, not contracted rates or confirmed tallies; each row links to the carrier’s own advisory.Posture key: Rerouting means Hormuz calls dropped but cargo still moving, via the Cape or escorted convoys; Suspended means no transits and no reroute announced. A carrier’s own advisory may say “suspended” about its Hormuz calls while we class the line as rerouting because its cargo still sails.Read the Hormuz figure, not the posture counts, for whether the strait is being used. Most of these lines moved Asia–Europe services to the Cape of Good Hope, which is a Red Sea decision and says nothing about Hormuz. 5 of 9 advisories describe stopping Hormuz or Gulf service, 0 describe reduced or escorted service still running, and 4 make no claim about the strait either way. The verdict counts only advisories from the last 60 days: that’s 1 of the 5, not all 5.

    Maersk

    Maersk has suspended bookings to Iraq, Kuwait, Qatar, Bahrain, Saudi Gulf ports, Jordan and most UAE ports. It discharges at Fujairah and Khor Fakkan, outside the strait, and moves cargo overland to Jebel Ali, and it charges USD 1,000 a container on any vessel that transits the Strait of Hormuz, on top of an Emergency Freight rate. Its Update 46 of 11 September 2026 sets that rate at USD 1,800 per 20-foot dry container, USD 3,000 per 40-foot dry container and USD 3,800 per reefer, special or dangerous-goods container, on cargo loading from or bound for Iraq, Kuwait, Saudi Arabia (Dammam and Jubail), Bahrain, Qatar, the UAE and Oman (except Salalah). The surcharge figure shown is the USD 1,000 per-container transit fee, not the Emergency Freight rate. It said on 25 June that three of its vessels remained in the Gulf.

Watch this number when headlines break. It’s a stress gauge for Iran’s economy: when people rush into hard currency, the rial price of a dollar climbs.
