Hiring a supertanker to carry Saudi crude to China passed $1.2 million a day for the first time on record in the week to Friday 25 September 20261. Fifteen days earlier the same run paid $862,150 a day, a rise of 43 per cent2. The trade quotes that rate on an index called Worldscale, where 100 is the notional break-even cost of a voyage, recalculated each January for every route. The Ras Tanura to Ningbo run is the Baltic Exchange's benchmark, and it was assessed at Worldscale 1,157.5 against 821.11 on 10 September, roughly eleven and a half times the baseline3. Brokers on a daily panel set that figure, and no cargo transacted at it.
Crude climbed over the same span and then surrendered the gain. Brent November futures stood at $107.35 a barrel shortly before 08:00 GMT on Monday 28 September, after President Donald Trump rejected Iran's offer to reopen the strait4. They settled that session at $105.28 and stood at $97.68 at 22:47 UTC on Wednesday 30 September, roughly 9 per cent below the peak5.
Refiners and shipowners meet those two prices at different points in the chain. The refiner buying the cargo pays the freight, not the shipowner carrying it, so the cost lands in the delivered price of a barrel rather than in the Brent headline. It then reaches the pump. American retail diesel averaged $6.382 a gallon in the week to 28 September, 70 per cent above a year earlier, against 43 per cent for petrol6. Buyers are still taking the cargo: India's September imports ran at 575,000 barrels a day from Iraq and 566,000 from Saudi Arabia, back to pre-conflict rates7.
Underwriters add a second charge the crude quote never shows. War-risk cover is priced as a percentage of what the ship itself is worth and charged per voyage, so 3 per cent on a $100m tanker is $3m for a single trip. Calls at Yanbu on the Red Sea have tripled to about 3 per cent from under 1 per cent in early July 20268. Southern Saudi ports stand at 7 per cent, and Hormuz runs at 6 to 9 per cent on assessments from Lloyd's List Intelligence and Dryad Global, and at 7.5 to 12.5 per cent on another market report the same week9. Underwriters are quoting the same transit at two different prices, which means the market has not settled what the risk is worth. Rerouting to the Red Sea was the escape from the strait, and Aramco has already pushed barrels that way, but the underwriters have priced most of the saving away.
