Diesel jumps to a four-month high as refinery attacks tighten supply
ICE gasoil futures, the global diesel benchmark, climbed as much as 4.2% to their highest level since April 9 after fresh attacks on refineries hit a market already short on barrels from the wars in the Middle East and Ukraine. For anyone hauling freight or hauling fuel, that is the number that matters this week. Diesel is the input you can't hedge away, and it just got more expensive.
The move feeds straight into fuel surcharges. Most carrier surcharge tables reset off a weekly pump average, so a spike in the wholesale market shows up in shipper invoices on a lag of a week or two. Carriers running current surcharge programs recover part of this. The ones on flat contract rates or stale surcharge floors eat it until the next renegotiation. Fuel jobbers delivering to fleets get squeezed from both ends: higher rack cost going in, and freight cost on their own delivery trucks going up at the same time.
The crack spread
Diesel's premium to Brent crude, the crack spread, is still high after hitting a record last month. Refiners make more money turning a barrel into diesel right now than they have in a long time, which normally pulls more product to market and cools the price. It hasn't yet, because the tightness is on the supply side, not demand. When the crack stays wide and prices keep climbing, the market is telling you barrels aren't reaching buyers fast enough. Watch whether refiners can lift diesel yield into this margin, or whether the outages keep a lid on runs.
Russian LNG sanctions
Russia has roughly doubled its "dark fleet" of opaque-owned tankers moving liquefied natural gas out of the sanctioned Arctic LNG 2 project, from about 11 carriers in December to at least 20 now, per a Bloomberg vessel-tracking analysis. That includes a second year-round ice-class ship. This is a gas story, not diesel, but it's the same picture: sanctioned barrels finding workarounds and staying in the global supply pool. It matters to US operators only as a read on how much sanctioned energy keeps flowing despite the rules, which shapes crude and product prices everywhere.
What to watch
Whether the refinery outages get repaired or spread further is the near-term driver on diesel. If runs recover, the wide crack spread could pull the price back down. If the attacks continue, surcharge tables keep ratcheting up and contract carriers on fixed rates stay underwater. Watch the weekly pump average that feeds your surcharge program, and watch whether shippers push back on the surcharge resets when the invoices land.
