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
Slovakia
Slovakia
Slovakia says it dropped its hold-out on the 21st sanctions package only after Ursula von der Leyen personally signed written gas-price and supply guarantees. The Council of the European Union's own 17,238-character release on the package names neither Slovakia nor any guarantee, leaving Bratislava's account unconfirmed by the institutional record.
EU regulator on capacity mechanisms
EU regulator on capacity mechanisms
Brussels is watching Germany's StromVKG first 4.5 GW capacity auction move toward its 8 September bid deadline without a resolved state-aid clearance for the 9 GW 2026 programme's gas-plant subsidies. A negative spark spread this deep on cheap gas strengthens the case for subsidised dispatchable capacity, the same case still awaiting a state-aid ruling.
French power exporters
French power exporters
French day-ahead cleared EUR 41.13/MWh on Sunday 26 July, EUR 43.09 below Germany, on wind more than doubling and a demand trough, not on any nuclear recovery. The desk expects the discount to hold only as long as French wind and weekend demand repeat, not as a durable nuclear-cost advantage.
European gas storage operator
European gas storage operator
A storage operator stopped bidding for prompt TTF cargoes on 21 July, reading the strike-halt unwind as the start of a fuel-side correction rather than a floor. It expects the gap between prompt and forward gas to keep narrowing as the war premium continues leaving the curve.
German gas-fired power fleet

German gas-fired plants cut output from 4.37 GW to 2.85 GW between 24 and 27 July, even as TTF fell 8 per cent, because below roughly minus EUR 40/MWh the fuel price stopped deciding dispatch. The fleet expects no relief until wind eases or StromVKG's first 4.5 GW auction adds capacity.
French industrial power consumers

France's day-ahead discount to Germany has nearly closed as TTF and EUA rise together on both sides of the border, eroding the arbitrage French industry relied on through the summer. A standing negative spark removes the German demand buffer that kept that spread wide.
