Bunker Prices Push Past $900 in Singapore as the Same Pipeline Shock Hitting Diesel Reaches Ocean Fuel

Marine fuel prices tracked by Ship & Bunker show Singapore VLSFO at $916.50 a metric ton as of Sept. 17, against $731.50 in Rotterdam, $808.00 in Houston and $1,028.00 in Fujairah. Marine gasoil (MGO) is running even higher across the board: $1,464.00 in Singapore, $1,530.50 in both Rotterdam and Houston, and $1,740.00 in Fujairah.

The driver is the same one now showing up in truck diesel prices: Saudi Arabia's Sept. 11 shutdown of its East-West Crude Oil Pipeline, closed after drone attacks originating in Iraq, according to reporting from CNBC and CNN. The pipeline normally carries roughly 7 million barrels a day, bypassing the Strait of Hormuz on its way to the Red Sea port of Yanbu; with it shut, more regional crude is routing back through the strait, and refiners and bunker suppliers from the Gulf to Northern Europe are pricing in the risk that the closure runs longer than a few days.

The port-to-port spread is the story

What stands out in today's numbers isn't just the level — it's the gap. Singapore VLSFO, at $916.50, is running $185 above Rotterdam's $731.50, a spread wide enough to change fueling decisions on any voyage with flexibility in its bunkering port. Fujairah, at $1,028.00, sits closest to the geopolitical exposure driving the spike: it's the main bunkering hub for vessels transiting the Gulf of Oman, the same corridor now carrying the rerouted crude that the East-West pipeline normally bypasses.

That geography matters operationally, not just financially. FreightWaves reported this week that Fujairah bunkering activity has recovered to only about 40% of pre-conflict levels, and that daily commodity-vessel transits through the Omani corridor — normally 10 to 15 a day — fell to single digits over the most recent weekend. A bunker port running at 40% of normal throughput is a port where fuel availability, not just price, becomes a planning variable.

What it means for ocean capacity buyers

Bunker adjustment factors on most ocean service contracts reprice monthly or quarterly rather than weekly, which means today's spot bunker numbers are a leading indicator for BAF conversations that haven't happened yet. Three things worth tracking:

Where carriers choose to fuel is about to matter more. With Rotterdam trading $185–$300 below Singapore and Fujairah, expect carriers with routing flexibility to lean harder toward European and U.S. Gulf bunkering where voyage patterns allow, and to pass a larger surcharge on strings that depend on Singapore or Fujairah fueling with no alternative.

Older tonnage carries more exposure. FreightWaves' review of China–U.S. West Coast container costs found newer, more fuel-efficient vessels absorbing roughly $155–$269 per 20-foot container in added fuel cost, against $360–$626 for older ships on the same routes — a gap of up to $470 per box tied entirely to vessel efficiency. Shippers booking capacity on older strings should expect a proportionally larger BAF hit than those on newer tonnage, all else equal.

Fujairah is a capacity risk, not just a price risk. A bunkering hub running at 40% of normal activity, in a corridor seeing single-digit vessel transits on a route that normally carries 10–15 a day, raises the odds of fuel-availability delays for any voyage dependent on that port — separate from, and potentially compounding, the price increase itself.

What to watch

The pipeline's operational status is the number that matters most here, exactly as it is for truck diesel. A reopening would likely ease both Singapore and Fujairah pricing quickly, given how directly this spike traces to the closure; a prolonged shutdown would keep the port spread — and the incentive to route bunkering accordingly — in place through Q4 contract negotiations.
