War-Risk Repricing: Why a Single Hormuz VLCC Voyage Now Costs $10m to Insure

As hull-war underwriters impose covenants on Saudi-linked tonnage and carriers stack emergency surcharges lane by lane, the cost of moving cargo through the Gulf is being rewritten faster than the disruption itself. Owners still fixed on old terms face a widening force-majeure gap.

How the Gulf Cost Stack Was Rewritten in a Fortnight

Marine underwriters have moved first. Following the recent run of Houthi strikes on Saudi-linked ships, hull-war insurers are tightening cover — imposing operational constraints and short-notice cancellation clauses on any vessel with a Saudi nexus, per Lloyd’s List. The terms are hardening ahead of the cargo.

The headline number is stark. War-risk premiums for a Strait of Hormuz call have surged to 7.5% to 10% of hull value, which can translate into roughly $10m on a single VLCC voyage. That is a cost line that did not exist in meaningful size a month ago.

The trigger was unambiguous. On 28 July the 50,000 dwt Saudi product tanker NCC Ghazal was struck by Houthi anti-ship missiles in the Red Sea and forced back to port, hardening every underwriter’s view of the risk in a single afternoon.

The Surcharge Wave Hitting Every Headhaul Lane

Carriers Are Stacking Emergency Fees Faster Than Shippers Can Model

The carriers followed the insurers. CMA CGM will levy emergency fuel surcharges from 1 August — $150 per TEU on dry and $165 on reefer for headhaul cargo, and $75 and $90 respectively on backhaul and intra-regional trades, according to Loadstar. ONE has moved on similar lines.

The surcharges are not confined to the Gulf. Maersk lifts its Far East–Latin America peak-season surcharge by $750 per TEU from 3 August (14 August for South Korean origins), while MSC updates its European short-sea emergency fuel surcharge from 10 August at $26–62 per TEU dry and $39–92 reefer, on Container News figures.

Insurers repriced the risk, carriers repriced the freight, and the shipper is now paying twice for the same strait. The surcharge is the disruption made visible on the invoice.

Spot Rates Are Confirming the Squeeze

The spot market has ratified the move. Rates from India’s JNPA to Dammam in Saudi Arabia have jumped 40–50% to about $6,500 per TEU and $7,500 per FEU, as capacity tightens on the lanes most exposed to the conflict, per Loadstar.

This is the cost cascade in sequence: hull-war premium, bunker surcharge, then spot repricing, each layer compounding the last. For a shipper on a Gulf headhaul lane, the all-in cost of a box has moved materially in weeks, not quarters.

Is the Market Pricing a Risk the Ships Are Ignoring?

There is a case that the repricing has run ahead of the disruption. Despite the blockade rhetoric, Linerlytica tracked 54 containership transits through the Bab el-Mandeb in a single week, with Maersk, CMA CGM and Wan Hai holding their Suez strings unchanged.

If the ships keep sailing, the premium is insuring a fear as much as a fact. That gap between priced risk and realised risk is exactly where refunds and disputes are born.

The sharper commercial danger sits in the paperwork. The current threat level may not clear the high legal bar for force majeure under standard BIMCO war-risk clauses, per Lloyd’s List — leaving owners and charterers exposed to disputes over who absorbs the elevated cost when neither can walk away cleanly.

What Owners and Charterers Should Lock Down Now

Owners should confirm their war-risk cover terms in writing before fixing, and price short-notice cancellation risk into voyage economics rather than assuming continuity of cover.

Charterers should read their BIMCO war-risk and force-majeure clauses now, not after a diversion, and clarify surcharge pass-through in fixtures before the next escalation moves the cost base again.

Both sides should treat the surcharge stack as sticky. Fuel and war-risk levies are quick to impose and slow to withdraw; budgeting for their removal on any near-term horizon is the least safe assumption on the desk.
