Market Overview
Oil prices eased in Asian trading on Thursday, with Brent crude futures for November delivery slipping 1% to $102.10 a barrel and West Texas Intermediate (WTI) futures falling 0.7% to $91.50. The decline followed a sharp rally the previous session, during which Brent rose nearly 4% and WTI climbed almost 2%.
Diplomatic Context
The price swing occurred against a backdrop of heightened US‑Iran tensions. Iranian President Masoud Pezeshkian addressed the United Nations General Assembly, asserting that Iran would not capitulate to US pressure while remaining open to diplomatic resolution. The day before, US President Donald Trump warned that he could "annihilate" Iran if a cease‑fire deal was not reached. A senior Iranian official told Reuters that Tehran was reviewing Washington’s response to an Iranian proposal to end hostilities, noting that significant differences persisted. Indirect talks have touched on the possible reopening of the Strait of Hormuz and the lifting of a US naval blockade.
Strait of Hormuz and Regional Supply
The Strait of Hormuz, which carries roughly 20% of global oil and gas shipments, remains a focal point. Iranian security chief Mohsen Rezaei stated that the waterway would stay closed until Tehran’s conditions are satisfied. Concurrently, Gulf supply dynamics have constrained further price gains: Saudi Arabia has restarted operations on its East‑West pipeline to the Red Sea, and Iraq has increased its crude exports, planning to raise shipments through Turkey.
US Diesel Export Rumor
U.S. diesel futures fell sharply after a report suggested the White House was considering a 90‑day ban on diesel exports. The administration later dismissed the report as "fake news," limiting any immediate market impact.
Inventory Data
According to the U.S. Energy Information Administration, U.S. crude inventories rose by 3 million barrels in the week ended 18 September, reaching 426.4 million barrels, well above analysts’ expectation of a 640,000‑barrel draw. Gasoline inventories declined by 1.7 million barrels, while distillate inventories—including diesel and heating oil—fell by 400,000 barrels. The inventory build in crude contrasts with the draw in gasoline and distillates, a factor noted as particularly relevant for the diesel market, where supplies remain under pressure despite the crude stock increase.
Market Implications
The combination of renewed geopolitical risk, mixed diplomatic signals, and a modest rise in U.S. crude stocks contributed to the 1% pull‑back in Brent and the 0.7% dip in WTI, tempering the gains from the prior day's rally.
