TD3C hits WS372 as hull cover reaches 5%

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 July 1. War-risk hull cover for Hormuz transits widened the same day to 3-10% of hull value, with 5% emerging as the market norm 2, 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.

Different Perspectives
Shipping and insurance industry
Shipping and insurance industry
UKMTO counted about 20 US-facilitated Hormuz transits a day to 11 September against only 6 visible on AIS, with traffic still around 90% below the 138-a-day pre-war baseline. War-risk underwriters cannot price hulls they cannot see, or resolve whether the tanker El Gaia hit a mine, as Iran claims, or a missile and drone, as CENTCOM says.
European refiners
European refiners
European refiners, including Poland's Orlen, absorbed a roughly $26 gap between Dated Brent at $130.80 on 15 September and ICE Brent futures settling at $103.87 on 18 September, a spread that widened from $13.45 on 9 September rather than newly opening. Their futures hedges no longer cover what they now pay for physical barrels.
Saudi Arabia
Saudi Arabia
Saudi Aramco zeroed European term customers' October allocations and rerouted roughly 60 million barrels to Asia through Ras Tanura and Sohar, using Red Sea and Gulf terminal capacity built years ago to cut Hormuz exposure. Riyadh reallocated existing supply rather than negotiating a shortfall with Europe.
Qatar
Qatar
Qatar's energy minister Saad al-Kaabi told Bloomberg at the Qatar Economic Forum on 20 September that Bessent's two-year Hormuz-obsolescence forecast is wrong, and that Doha has deliberately built no bypass pipeline. Qatar's gas exports run through one waterway by choice, not oversight.
Iran (foreign ministry and Majlis)
Iran (foreign ministry and Majlis)
Iran's foreign ministry and 130 Majlis deputies moved toward NPT withdrawal this week, with lawmaker Hossein-Ali Haji Deligani filing a triple-urgency bill on 20 September that Speaker Qalibaf has not yet scheduled. Tehran treats treaty membership as leverage still on the table, not yet spent.
Russia and China
Russia and China
Moscow and Beijing vetoed the Panel of Experts' renewal, maintaining Resolution 2231 lapsed in October 2025 and the 2025 snapback was never validly triggered, so the sanctions architecture the Panel enforces has no current legal standing. Both governments frame the veto as upholding law, not shielding Tehran.
