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
Lloyd's Market Association
Lloyd's Market Association
War-risk underwriters price the Houthis' Red Sea attacks because the group announces its targets in advance, but the unclaimed Damietta drone gives insurers a hit with no author to price against. An attack nobody claims costs shipping more than one that is claimed, since premiums are set against a known pattern, not raw damage.
US Central Command
US Central Command
CENTCOM has announced no strike on Iran since resuming bombing on 30 July within hours of an IRGC salvo on Jordan, and centcom.mil did not respond to requests to confirm any pause. The command has gone quiet before while a larger operation was being weighed, so silence alone proves nothing about what it has or has not done.
Hengaw
Hengaw
Hengaw recorded at least 67 executions in Iran during July, of which the state acknowledged only eight, and reported the 1 August execution of protest detainee Arvin Kheirkhahan at Shahrud with no advance notice to his family. A family's first notice of a death sentence is now usually the instruction to collect a body.
Egypt
Egypt
Egypt's government asked media on 2 August to report the Damietta attack accurately, named no author, and said no findings will be published before its own investigation concludes. Cairo holds the debris and jurisdiction over an attack on its own soil, and naming a culprit now would pull it into a dispute it has avoided for five months.
Iran's Foreign Ministry
Iran's Foreign Ministry
Araghchi called the Hormuz talks with Oman final-stage on 2 August, four days after his own deputy rejected Oman's lane proposal, and denied the Damietta drone strike as an Israeli false flag while two Iranian officials privately claimed it for Tehran. Iran's public position now contradicts itself on both files at once.
Bahrain and Kuwait
Bahrain and Kuwait
Bahraini and Kuwaiti aircraft flew their own strikes on Iranian depots in July with Emirati air cover behind them, and Ynetnews reports some Gulf capitals wanted the 2 August strike to proceed rather than stop. States that have already taken fire see a closing window on Iranian weakness, not a reason to pause.
