Oil Falls As Traders Weigh Hormuz Attacks, IEA Diesel Warning

Oil prices fell on Thursday as traders assessed possible supply disruptions after attacks on ships in the Strait of Hormuz and digested the International Energy Agency’s October oil report. Brent crude for December delivery dropped 1.66% to $104.31 a barrel, while U.S. West Texas Intermediate for November fell 1.09% to $94.05 per barrel.

Ship Sunk In Hormuz

A Singapore-registered ship was sunk in the critical Strait of Hormuz, raising fears of a prolonged Middle East conflict. The Singapore maritime authority said in a statement on Wednesday: “Such attacks are unprovoked, unjustifiable and a breach of international law.” Iran has said it is “counting the moments” until it can start striking U.S. warships.

IEA Flags Diesel Market Tightness

The International Energy Agency, in its oil report for October out Wednesday, cautioned that constraints on diesel markets could continue well into next year. Fresh attacks on Saudi Arabia threaten to derail a recovery in oil supply, the IEA said.

To help ease prices, the Trump administration is considering easing sanctions on “shadow fleet” vessels that transport oil and petroleum products from countries such as Russia, Reuters reported.

Diplomacy And Market Buffers

The lack of progress between the U.S. and Iran diplomatic track “leaves little immediate prospect of a full reopening of the waterway,” said Firas Bechwaty, head of business development at online trading platform ICM, late Wednesday.

“At the same time, Saudi crude continues to reach international buyers through alternative routes, while accelerated emergency stock releases by IEA members provide an additional buffer, preventing a sharp rise in prices, even as tensions remain elevated,” Bechwaty noted.

For Nigeria, lower Brent prices can reduce the foreign exchange earned per barrel, but they may also soften imported fuel costs if the decline is sustained. The bigger risk is diesel. If the IEA’s warning plays out, Nigerian businesses that rely on diesel for power and transport could face persistent cost pressure, even as crude prices ease.
