The Baltic Exchange assessed the Middle East Gulf to China VLCC route at WS372 on 17 July, and Hormuz war-risk hull cover widened the same day to a 3-10% band with 5% the emerging norm.

Key takeaway

War-risk cover at 5% of hull adds roughly $2.50 a barrel to a Gulf cargo, twice the late-June loading.

The Baltic Exchange assessed the TD3C Middle East Gulf to China VLCC route at WS372 on Friday 17 July, roughly 15 Worldscale points above the previous Friday and about 27% above the WS293.89 print of 3 July⁠1. War-risk hull cover for Hormuz transits widened the same day to 3-10% of hull value, with 5% emerging as the market norm⁠2, against the 3-4% baseline this desk recorded in late June.

Put that in cash. On a $100m VLCC, 5% is $5m a voyage against roughly $250,000 before the war, or about $2.50 a barrel across a 2m-barrel cargo. The loading has doubled from the $1 to $1.50 range of a month ago, and it sits on top of the freight rate rather than inside it.

War-risk cover is the slowest instrument in the complex to move and the hardest to talk down, because it reprices on the London market's read of loss frequency rather than on political signalling. The Lloyd's Joint War Committee listed-areas mechanism compounds that: a single insurable casualty inside a designated zone moves the whole quoted band, which is how 3-4% became 3-10% in one step instead of drifting. Underwriters moved when two UAE supertankers were actually hit, and not when ministers issued statements about the strait.

This breaks the pattern the desk has traded since late June, when the TD3C 4Q26 forward sat at $181,163 a day and would not budge while Brent shed 8%. Charterers who took that forward cover are now materially in the money against a WS372 spot, so paper freight length is quietly subsidising physical programmes. The reverse trade deserves naming too: both legs can retrace far faster than a premium priced into the curve, and if the strike tempo slows, freight and hull cover come off before the flat price does.

Deep Analysis

In plain English

Shipping companies charge more to move oil through dangerous waters, and insurance companies charge more to cover ships that might get attacked. For weeks, both prices stayed calm even as oil itself got more expensive, because nobody had actually been hit. Then real ships were struck in The Gulf, and both the shipping cost (TD3C) and the insurance cost (war-risk cover) jumped at once, showing the danger had become real rather than just talked about.

Deep Analysis
Root Causes

War-risk hull cover resets on the Lloyd's Joint War Committee's listed-areas framework, which prices a designated zone on evidence of loss frequency rather than on political announcements; two UAE supertankers struck supplied the actuarial trigger that six weeks of diplomacy could not.

Freight lagged separately because owners holding 4Q26 forward cover at $181,163/day were pricing a physical Hormuz recovery in months, a bet that two strikes in one week directly undercut.

What could happen next?
  • Consequence

    A European refiner buying a Gulf VLCC cargo now pays flat price plus roughly $2.50 a barrel in insurance plus the WS372 freight uplift, raising the delivered cost floor independent of any further crude price move.

  • Risk

    If the strike tempo continues, hull cover could move toward the top of its quoted 3-10% band, since the Joint War Committee mechanism reprices on each new casualty rather than settling at a fixed level.

The OBR's 28 October forecast assumed $82 oil for 2026 and 2027, from market prices for the ten working days to 19 August, and blamed dearer wholesale energy on the war without naming Iran. It expects CPI inflation close to 4% in early 2027 even at that price.

Hengaw reported the 3 November hangings of Amirhossein Maleki and Amirhossein Ebrahimi in Isfahan, saying Ebrahimi was tortured into confessing and that nine of 12 people sentenced to death in the case have now been hanged. Iran's judiciary holds that the defendants killed members of the security forces.

Treasury designated an alleged Chandigarh false-flag network on 4 November and eight Canadian exchangers on 6 November, while State sanctioned alleged MANPADS intermediaries. None of the actions touches an oil buyer; they target the paper, cash and procurement around Iran's trade.
