Hormuz goes dark as tankers flee

3 min read

Hormuz transits fell to about two a day as three vessels were struck overnight, and Iran routed the strait's governance through Oman, yet Brent crude slipped to about $75.80.

Key takeaway

Ships have stopped crossing Hormuz, yet Brent fell to about $75.80, a physical crisis the oil price refuses to confirm.

Tanker transits through the Strait of Hormuz collapsed to about two on 9 July, from a near-pre-war rhythm of 35 to 51 a day earlier in the month . 1 Three vessels were struck overnight as they ran outbound: the liquefied natural gas (LNG) carrier Al Rekayyat, already reported , and the crude tankers Wedyan and Cyprus Prosperity, which earlier coverage never named. 2 The 7 July strike was therefore a wider, multi-vessel attack than first recorded.

The Joint Maritime Information Center (JMIC), which advises commercial shipping, holds its Hormuz advisory at "severe", its highest tier. War-risk insurance now runs at 2 to 6 per cent of hull value, below a wartime peak near 10 per cent, but London brokers report fewer quote requests, not more. 3 Owners are abandoning the strait rather than paying to cross it: the cost is no longer a premium on a crossing but a route nobody will take.

Oil fell anyway. Brent went from $78.67 on 8 July to $76.97 on 9 July and about $75.80 on 10 July, handing back roughly a quarter of the strike gain. 4 Physical shipping data reads as crisis; the price reads as contained .

Article 5 of the ceasefire memorandum, over who controls Hormuz, is the sticking point stalling the Witkoff-Kushner Doha channel: Iran wants sole managerial authority, the US wants unrestricted transit. 5 With that channel frozen, Mohammad Bagher Ghalibaf, Iran's parliament speaker, says Iran and Oman have reached a separate Hormuz-management agreement based on the same memorandum, routing the strait's governance through Muscat rather than Washington. 6 That deal advances a bilateral Hormuz track Tehran and Muscat have been in continuous consultations over since May rather than opening a fresh one, and Ghalibaf had already declared the memorandum violated days earlier . The International Institute for Strategic Studies (IISS) assesses that no military option can reopen the strait for either side, only negotiation. 7

Deep Analysis

In plain English

The Strait of Hormuz is the narrow sea passage between Iran and Oman that roughly a fifth of the world's oil, and a third of its liquefied natural gas, has to pass through. Ships have almost stopped using it: only around two tankers a day are getting through, down from 35 to 51 a day earlier this month. Three ships were hit overnight, two crude oil tankers and one gas carrier, and insurance companies have made cover so expensive that most shipowners are choosing to avoid the route entirely rather than risk it. Iran's parliament speaker says Tehran has now struck a side deal with neighbouring Oman to manage traffic through the strait, separate from the wider ceasefire talks with the United States that remain frozen.

Deep Analysis
Root Causes

Iran's ability to contest transit at all rests on a legal gap: Tehran has never ratified the UN Convention on the Law of the Sea, the treaty that would otherwise guarantee foreign vessels transit passage through the strait, so its domestic maritime claims face no binding international constraint it has itself accepted.

The collapse in transits is also an insurance-market mechanism alongside the security one. War-risk cover at two to six per cent of hull value makes a single voyage prohibitively expensive without a state guarantee behind it, which is why owners are diverting rather than paying the premium and hoping.

Escalation

The Oman side-deal and the frozen Doha channel are now running as separate tracks. Whether Muscat's narrower arrangement de-escalates the maritime dimension while the wider ceasefire memorandum stays stalled, or whether owners hold out until both resolve, will show in the next transit-count reading.

What could happen next?
  • Consequence

    A bilateral Iran-Oman arrangement running outside the Doha channel means Hormuz's reopening no longer depends solely on US-Iran talks.

  • Risk

    War-risk premiums at two to six per cent of hull value keep the route commercially unviable regardless of any diplomatic deal, until underwriters see a sustained run of unstruck transits.

Different Perspectives
Shipping and insurance industry
Shipping and insurance industry
UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.
European refiners
European refiners
European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.
Saudi Arabia

Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.
Qatar
Qatar
Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.

Iran (foreign ministry and Majlis)
Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.
Russia and China
Russia and China
Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
