Commodities Wrap 15 September: Diesel Jumps 6 Percent as Saudi Loadings Halt and WTI Outruns Brent

By The Edge Research Team

The petroleum complex led everything we track on Tuesday, with ULSD heating oil up 6.07 percent at 5.2626 dollars a gallon at 19:00 GMT, after the settlement window and WTI, up 4.35 percent, outrunning Brent, up 2.69 percent, after shipping industry sources told Reuters that oil loadings at Saudi Arabia’s Red Sea port of Yanbu had been suspended, and Libya’s National Oil Corporation said operations at 2 oilfields and a pumping station were suspended. At the settlements, WTI closed 4.4 percent higher at 105.83 dollars a barrel, its highest close since 19 May, and Brent settled 2.9 percent higher at 108.75, per CNBC’s written report for the session, both arithmetic checked against Monday’s settlements.

Yanbu stops loading and the barrel Europe cannot get bids up the one America can

The supply picture tightened from 3 directions at once. The suspension at Yanbu came after Riyadh told European customers that some late September cargoes would be cancelled, itself the consequence of Friday’s strike on the East-West pipeline, a route whose loss threatens up to 4 percent of global supply on the wire’s account; buyers and traders told the wire Saudi Arabia could exhaust crude available for export within days unless the pipeline resumes, while the United States energy secretary said it should be flowing within days and a Goldman Sachs note put the repair range anywhere from very soon to 8 weeks, with a higher probability of Brent above 120 dollars. In Libya, separately, the National Oil Corporation suspended operations at 2 oilfields and a pumping station, with force majeure possible, and commodity vessel traffic through the Strait of Hormuz fell to 4 on Monday from 10 a day earlier on preliminary tracking data carried by the wire. The market’s answer was in the spreads: WTI outran Brent, with an analyst telling the wire that the cancellation of Saudi shipments to Europe strengthens expectations European refiners will turn to United States supplies, and diesel outran the crudes outright, RBOB gasoline just behind WTI at 4.32 percent higher, with diesel, at a more than 4 year intraday high and on track for a record close on the wire’s account, squeezed further by half of Russia’s 6 top diesel producing refineries significantly cutting or halting output this month on the wire’s calculations.

Crypto and the softs sell while metals sit out the shock

Outside energy the day ran the other way. Bitcoin fell 4.01 percent to 75,912.20 dollars and Ether 5.54 percent to 2,401.02, the board’s deepest declines, and the Cboe Volatility Index rose 1.87 percent to 17.42 with the United States cash session still open. The softs sold with them, cocoa down 2.71 percent and coffee 2.46 percent, while the grains firmed, soybeans up 1.15 percent and wheat 0.80 percent. The metals sat out the shock almost entirely: copper added 0.98 percent, palladium 0.44 percent and platinum 0.40 percent, and gold stood 0.06 percent lower at 4,349.30 dollars an ounce. Monday’s wrap set the marker for this market: a Brent settlement above 107.63 dollars would mean the relief from the shipping talks had fully unwound. Brent settled at 108.75, 1.12 dollars above that line.

Contract months as displayed. Corn (Dec’26, 535.75 cents a bushel, up 0.47 percent) and cotton (Dec’26, 84.50 cents a pound, down 0.06 percent) are omitted to keep the table lean.

Rates, currencies, volatility and crypto

Intraday quotes at 19:00 GMT, ranked by change; snapshot levels of continuously traded instruments, not settlements, with the United States cash session still open, so the VIX row is an intraday level rather than a closing print. Euro/Dollar (1.1542, down 0.04 percent) is omitted to keep the table lean.

Why it matters: the energy shock is broadening from the crudes into the products, on our reading: diesel, not Brent, led the board, because the pipeline and port disruptions bite hardest in refined fuel that Russia’s curtailed refinery runs can no longer replace. The rest of the board priced the other side of the same day, crypto and the softs selling while the metals barely moved, a risk positioning story rather than an inflation one. Across everything we published today, the EGX 30 is the day’s best index at 0.21 percent higher and Singapore’s Straits Times the worst at 1.39 percent lower.

Outlook: the Federal Reserve decides on Wednesday, with a quarter point rise priced and further tightening indicated, per Reuters, and our US wrap follows tonight. For this board the week turns on the East-West pipeline: the repair estimates the wire carries run from days, per the United States energy secretary, to 8 weeks, per the Goldman Sachs range it cites, and each week at the long end of that range keeps the products market where Tuesday left it.
