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 →
Transit through the Strait of Hormuz has been halted by fresh attacks on shipping as Brent falls 5.6% in 24 hours, with the latest official PortWatch count from July 19 as Tehran's open-market dollar trades at 857,000 toman, down 3.1% on the week with crisis pressure at 91 (extreme).

How this is computed →Our two 0–100 gauges: how disrupted the strait is right now, and how much escalation markets price in for the next 30 days.
On JUL 19, IMF PortWatch's most recent published day, commercial transit through the Strait reached 17% of pre-crisis volume: 15 vessels against a typical 88 per day. Iran has re-declared the Strait closed; the US reports 17 ships still transiting, so PortWatch's weekly AIS-based count likely understates current flow. War-risk insurance for tankers now prices at 8.0× pre-crisis, with 6 P&I clubs withdrawing cover. Brent has moved -5.64% in the past twenty-four hours.

PortWatch logged 15 transits on 2026-07-19, against a pre-crisis baseline of 88 per day; port arrivals across Hormuz-area ports totaled 483 in the most recent 24 hours.
Situation
The Strait of Hormuz remains under acute operational stress. PortWatch's most recent published day, 2026-07-19, recorded 15 transits against a pre-crisis baseline of 88 per day, reflecting a severe throughput deficit. Port arrivals across the Hormuz-area ports on both the Persian Gulf and Gulf of Oman sides reached 483 in the most recent 24 hours; that figure uses a different methodology from PortWatch and the two should not be conflated. At 23:52 UTC, our AIS tracking showed 416 vessels anchored or stopped in the region, and 28 indexed events were recorded in the preceding 24 hours. The Hormuz Index state composite sits in the extreme band, with physical transit deviation as the top contributor, though it showed easing over the past 24 hours. The forecast composite sits in the elevated band, also easing, with Polymarket escalation contracts as the top contributor. The two composites diverge: extreme current pressure against an elevated but moderating forecast horizon. On pricing, Brent stood at $88.01 at 23:52 UTC, a 4.60% decline over the prior 24 hours. That drop tracks a third consecutive night without direct US-Iran exchanges, per gCaptain. Iran's state media outlet IRNA carried a statement from Khatam al-Anbia warning that continuation of what it characterized as a US naval blockade would broaden the conflict, a claim not independently confirmed. Trump separately told reporters that talks with Tehran were progressing and that a deal remained possible, per gCaptain.

The headline transit count above conflates traffic that energy desks read differently: a Capesize bulker and a VLCC are not the same signal. 141 vessels in the window are not holding position, broken down here.

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.

Toman per USD · Tehran open market
24h +0.00%7d -3.08%
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.
