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 6 vessels on August 30 at 7% of typical as Tehran's open-market dollar mid trades at 222,875 toman, up 6.1% on the week; crisis pressure at 90 (extreme).

How this is computed →Our two 0–100 gauges: how disrupted the strait is right now, and how much escalation markets price in. Read the second as a direction of travel, not a forecast for any fixed day.
On AUG 30, IMF PortWatch's most recent published day, commercial transit through the Strait reached 7% of pre-crisis volume: 6 vessels against a typical 85 per day. War-risk insurance for tankers prices at 40.0× pre-crisis on the latest trade-press read, with 6 P&I clubs withdrawing cover.

PortWatch counts AIS-broadcasting crossings only. Vessels that stop transmitting are not captured, and most of that gap looks like ordinary reception loss rather than deliberate evasion, so true flow may run higher than the figure above.

Tanker strikes in the Strait of Hormuz are pushing oil prices higher, per Finimize; this report is carried by a single outlet and is not independently confirmed.
- 02
As of 11:56 UTC, Brent trades at $96.28, flat over 24 hours (+0.00%); 302 vessels are holding position away from berth.
- 03
PortWatch recorded 6 transits on 2026-08-30, against a pre-crisis baseline of 85 per day; the Hormuz Index Crisis Pressure sits in the extreme band.
Situation
The Strait of Hormuz remains the focal point of an active and deteriorating maritime crisis. Finimize reports that tanker strikes are lifting oil prices, though that report is single-source and has not been picked up by additional desks. Iranian state media, which must be treated as a claim, says US and Iranian forces have exchanged strikes on vessels in the Persian Gulf, and that Iran is characterising its actions as self-defense against what it calls a maritime blockade; Washington has not confirmed the Iranian account of any strike on an American vessel, and the US has separately denied at least one Iranian strike claim, per India Shipping News. Iranian state media also claims shipping through the strait has fallen to its lowest level since May, averaging 10 commodity ships per day over the past 10 days; that figure is unverified. PortWatch's most recent published day, 2026-08-30, recorded 6 transits, against a pre-crisis baseline of 85 per day. At 11:56 UTC, Brent stood at $96.28, unchanged over 24 hours. The Hormuz Index Crisis Pressure composite is in the extreme band, easing over the prior 24 hours, with war-risk insurance acting as the single-component override driving that reading. The Escalation Forecast composite sits in the elevated band and is rising, with the Brent-WTI forward spread named as the top contributor. The two composites diverge: current-state pressure is easing at the margin while the forward-looking signal moves higher.

Transits by type.
Vessel mixCurrently transiting vessels grouped by type. The headline transit count above conflates traffic that energy desks read differently: a Capesize bulker and a VLCC are not the same signal. 104 vessels in the window are not holding position, broken down here. Transit is the residual of the anchored test, so read it as a ceiling.

Dark-tanker count83
tankers · last 24hof 202 screened▲ vs 7d baseline 70.9
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 7,629 vessels of every type ever recorded in the wider bbox since monitoring began.
That is 83 of 202 tankers that met the screen. Non-tankers that met the same screen went dark at 25.7% on the identical test. Read the count as a floor on hulls we stopped receiving: against that ambient dropout rate, the share attributable to deliberate evasion is not currently distinguishable.
Baseline averages the count over the last 168 hourly samples.

Container carriers.
CarriersThe nine largest container carriers by global TEU capacity, with their declared posture for Strait of Hormuz transit and the surcharge applied to twenty-foot equivalent units rerouted via the Cape. 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. 4 of 9 advisories describe stopping Hormuz or Gulf service, 3 describe reduced or escorted service still running, and 2 make no claim about the strait either way. The verdict counts only the first group.

The black-market USD rate Tehran’s trading houses quote when transacting. The government’s official rate is an administratively set, subsidized rate that sits far below what the open market charges and is not a price most Iranians can actually buy dollars at; the figure above is the rate they pay.
Watch this number when headlines break. The rial tends to move ahead of Brent on Iran escalation: capital flight into hard currency is faster than the oil futures re-pricing the same risk.
