War-risk cover sets a hidden cost floor

Western war-risk insurance has returned to the Gulf at 3 to 4% of hull value against 0.25% before the war, adding roughly a dollar to a dollar fifty a barrel to every VLCC cargo and setting a cost floor flat Brent does not show.

Key takeaway

Returning war-risk cover embeds a dollar-plus-per-barrel cost floor on Gulf cargoes that flat Brent does not show.

Western marine war-risk cover returned to The Gulf shipping corridor at 3 to 4% of hull value by 22 June, against 0.25% before the conflict, twelve to sixteen times the pre-war rate 1. War-risk insurance is the premium underwriters charge to cover a vessel crossing a conflict zone; at these levels the loading alone adds roughly $1 to $1.50 a barrel to the all-in delivered cost of a VLCC cargo. Mine clearance through Hormuz has not officially begun .

The transit counts and the mine-clearance timeline are the Iran desk's beat . A European freight desk carries the insurance loading directly, embedding a premium of a dollar or more a barrel into the delivered cost of every Gulf cargo. The flat Brent screen does not register that floor for eastern buyers, even as the screen treats the crisis as closed.

That embedded cost is part of why the forward freight curve has stayed anchored while the flat price fell: the tanker market is pricing the insurance and the physical risk, not the diplomacy. An insurance market still charging a war-risk multiple of this size is not one that believes the reopening is complete.

Deep Analysis

In plain English

Before a commercial tanker can sail, it needs two types of insurance. A hull and machinery policy pays the shipowner for physical damage to or total loss of the vessel. Protection and Indemnity (P&I) insurance pays for liability to third parties: crew injury, fuel spills, and damage to other vessels or port infrastructure. Banks that finance vessels and ports that accept them both require valid certificates for both types. Before the Hormuz conflict, war-risk insurance for Gulf transits cost roughly 0.25% of a vessel's hull value per voyage. On a large crude tanker worth $120 million, that was around $300,000 per crossing. This week, war-risk cover returned to the Gulf corridor at 3-4% of hull value, and P&I clubs have not yet reinstated standard terms for Hormuz transits at all. At 3-4%, the same $120 million tanker now carries $3.6 to $4.8 million in war-risk cost per voyage, translating to roughly $1-1.50 for each of the 2 million barrels on board. This extra cost does not show up in the $73 Brent crude price on the screen, but it is being paid by the buyers of Gulf crude on top of the headline price.

Deep Analysis
Root Causes

The 3-4% hull rate traces to three specific underwriting inputs that remain unresolved. First, the Lloyd's JWC "Additional Premiums" designation requires 30 consecutive days without a maritime incident in the listed area before a formal delisting review can begin; with 43 vessels still unaccounted for between CENTCOM and Kpler tracking as of 22 June, the JWC cannot start its 30-day incident-free clock because vessel status cannot be confirmed.

Standard P&I, North P&I, Gard, and Steamship Mutual have each issued Gulf withdrawal notices; without P&I cover a tanker cannot legally operate in any port requiring a valid club certificate.

Hull insurance pays for the vessel's physical structure; P&I pays for crew liability, pollution, and third-party damage, and no major bank financing a vessel will waive P&I as a loan covenant condition. A tanker operator who self-insures the hull still cannot satisfy port entry requirements or lender covenants without club membership.

Third, the 2023 Scandinavian Reinsurance Company (RNRC) precedent for Russian crude provides a structural parallel: after Western P&I clubs withdrew from Russian crude cargoes in 2022, Russia moved approximately 40 vessels to RNRC cover within three weeks; however, RNRC's capital reserves were insufficient to cover a catastrophic hull loss event, which is exactly the scenario P&I clubs are pricing at Hormuz.

The same capital-adequacy constraint applies to any non-Lloyd's substitute attempting to cover 270,000-tonne VLCC hull exposure in an active-conflict zone.

Different Perspectives
Shipping and insurance underwriters
Shipping and insurance underwriters
Kpler counted five Hormuz transits on 16 August against 31 the previous weekend, while Windward logged four vessels going AIS-dark for up to a month; underwriters price both the attacks and a sanctions register that names their counterparties in unreadable scanned images. Two trackers now measure only the ships that consent to be seen.
China
China
China sits at the end of the payment chain the 14 August designation targets: Iran's shadow banking network exists to convert sanctioned oil sales, much of it to Chinese refiners, into usable funds. Beijing has previously refused to recognise OFAC's jurisdiction over its own entities buying Iranian crude, leaving this designation to test compliance rather than change trade.
Qatar
Qatar
Qatar's foreign ministry denied on 16 August holding any Iranian pilots alive, contradicting Iranian General Mohammad Bagherzadeh's claim that Doha holds three Su-24 aircrew, and said it had recovered only one set of remains. Qatar carries Iran's messages to Washington, and this is a public break with Tehran over a fact only one aircrew inquiry can settle.
Oman
Oman
Oman's shipping-map talks, covering monitoring, environment and maritime services, were publicly decoupled from any Hormuz reopening by Iran's own foreign minister on 17 August. Muscat's mediation channel keeps functioning on the narrow file it was given, while the political decision it hoped to unlock stays with Iran's security council.
Saudi Arabia
Saudi Arabia
Saudi Arabia separately called the recurrence of tanker attacks on Emirati shipping a dangerous escalation, breaking from the UAE's repeated formula. Riyadh speaking in its own name over an attack on another state's vessels signals it reads the pattern differently from Abu Dhabi's flat statements.
United Arab Emirates
United Arab Emirates
The UAE foreign ministry condemned a third ADNOC-linked tanker attack on 15 August in language identical, word for word, to its statement the day before. Three consecutive strikes on Emirati shipping have not moved Abu Dhabi's public wording by a single adjective.
