Key takeaway

Gulf cargo stays put because of what it costs to insure, not because of what blocks it.

Brent crude traded at $92.09 at 01:30 GMT on Wednesday 22 July, up 1.2% and its highest since 11 June, a fourth consecutive daily gain 1.

War-risk premiums for a Strait of Hormuz transit now run at 3% to 10% of a vessel's hull value, against 0.25% before the war 2. On a $100 million tanker that is $3m to $10m a voyage where it used to be about $250,000. The largest vessels are quoted $10m to $14m, and the charge falls on the charterer rather than the owner.

Whoever books the ship pays that premium up front and adds it to the delivered cost of the barrels. A buyer with any alternative supplier declines the cargo, and the charter is never fixed. So a legal, licensed, fully insurable parcel of crude sits where it is, because nobody at either end of the voyage will carry a $10 million charge the barrels cannot recover. The Lloyd's Market Association is explicit that cover remains available: what suppresses transits is price and crew willingness, not capacity 3. Underwriting resets slowly, and crews have longer memories than markets.

CENTCOM (US Central Command) frames the same water differently. Its 21 July statement says US forces have facilitated the transit of roughly 900 commercial vessels and 450 million barrels of crude "since early May", redirected eight vessels and disabled one 4. No date window is attached to the 900-vessel figure, so it cannot be set against the 66% weekly fall in transits recorded on 21 July . The two counts cover different things over different periods.

In a note dated 20 July, Daan Struyven of Goldman Sachs set out an upside case of Brent above $120 by the fourth quarter, conditional on Hormuz disruption persisting and Persian Gulf flows staying below roughly 45% of pre-war levels 5. Goldman's base case is $80 in the fourth quarter and about $75 in 2027 6. The higher number describes what happens if nothing changes, not what the bank expects.

Deep Analysis

In plain English

Brent crude, the main international oil price benchmark, rose to $92.09 a barrel, its highest level since 11 June and the fourth straight daily rise. Oil often gets more expensive when investors worry that war could disrupt supply, even before that disruption actually happens. A lot of this price rise comes down to insurance, not ships actually being stopped. Sailing through the Gulf now costs shipping companies far more in war-risk insurance than before the war, and that extra cost is passed on. Insurers say enough cover is technically available, it has simply become expensive enough that some owners choose not to sail. Goldman Sachs, a major investment bank, has said oil could go above $120 a barrel later this year, but only if the situation gets significantly worse. Its actual expectation for now is closer to $80.

Deep Analysis
Root Causes

War-risk premiums of 3-10% of hull value, not a shortage of naval capacity or insurance cover, are what is keeping tankers from sailing the Gulf, according to the Lloyd's Market Association. For the largest vessels, insurers are seeking $10-14 million per Hormuz voyage, a cost charged to the charterer rather than the shipowner.

Because that liability sits with charterers and crews rather than a fixed physical bottleneck, the decision to sail is a commercial one made voyage by voyage, which is why price continues climbing even as CENTCOM reports it is still moving substantial volumes through the strait.

What could happen next?
  • Consequence

    If Gulf flows fall and stay below roughly 45% of pre-war levels through Q4, Goldman's contingent $120+ scenario becomes the operative case rather than its $80 base case.

  • Opportunity

    Because the Lloyd's Market Association says insurance capacity remains available, a de-escalation could unwind the price premium quickly, as happened after the 1990 Gulf War spike.

Different Perspectives
Shipping and insurance underwriters
Shipping and insurance underwriters
Underwriters can price Houthi strikes because the group announces its targets, but an unclaimed drone at Damietta and a mandatory Iranian insurance scheme both deny them a pattern to price against. War-risk premiums are increasingly being set by the absence of a claimant, not the scale of the damage.
Jordan
Jordan
Azraq absorbed its fourth Iranian strike in seven weeks, again drawing no direct Jordanian retaliation, only an American one. Amman's exposure, hosting US basing without the Patriot density of Gulf allies, has not changed even as the war around it widens.
Houthi movement
Houthi movement
The Houthis' 20 July blockade of Saudi-linked shipping is the injury Riyadh's new 43-nation coalition directly answers, yet the group itself was never asked to join and remains outside every proposal on the table. Sanaa-aligned commentators call the coalition a paper reassurance for insurers rather than a deployable force.
Egypt's Cabinet
Egypt's Cabinet
Egypt confirmed the Damietta blaze was an attack, not an accident, on soil the war had never touched before. Cairo now faces an unclaimed threat to a facility supplying roughly 7% of its domestic gas, with no author to hold accountable and no pattern yet to defend against.
Oman
Oman
Muscat is running the only channel Iran will use, a voluntary Hormuz fee modelled on Malacca, but stayed out of Saudi Arabia's new naval coalition entirely. Oman's mediating leverage depends on treating Hormuz as shared and non-exclusive, the opposite of what Tehran is now demanding of it.
Iraq's Prime Minister
Iraq's Prime Minister
Al-Zaidi cancelled his first official Riyadh visit and convened the Coordination Framework, the coalition that keeps him in power and whose factions sit inside the PMF that Saudi jets just struck. He is caught between a five-year Saudi investment relationship and armed groups inside his own state he does not fully control.
