NYMEX WTI Crude Front-Month Settles at $100.30 as Three-Session Decline Erases Weekly Gain
Saudi Arabia's pause on European crude sales drove WTI's third straight daily loss Friday, ending what had been a third consecutive winning week.
NYMEX WTI crude front-month for October delivery settled at $100.30 a barrel in New York at Friday's close (2026-09-18), down 1.6% on the session, as a three-day slide erased what had been shaping up as a third consecutive weekly gain. ICE Brent crude front-month for November settlement fell 0.9% to close at $103.87, Rigzone reported, cementing a narrow weekly loss for both benchmarks.5
Saudi Arabia pausing some crude sales to European buyers provided the immediate catalyst. Traders and analysts said existing supply buffers still hold for now, but the three sessions of losses shifted the week's outcome from fresh triple-digit highs to a small net retreat.5
The pullback comes after one of crude oil's most sustained runs in years. ICE Brent crude front-month has gained roughly 70% in 2026, according to Rigzone, as US-Iran military confrontations repeatedly threatened Persian Gulf shipping and pushed both benchmarks from the mid-$80s in August through triple-digit territory in September.5
The Strait of Hormuz has been the pressure point underpinning that move. Ship traffic fell to just 4 vessels per day during the most intense fighting, as reported on September 2 (2026-09-02), compared with the dozens of tankers that transit daily under normal conditions.2 EIA data pointed the same direction: American crude inventories fell by 4.45 million barrels in the week ending September 2 (2026-09-02), more than four times the consensus draw, leaving total stockpiles at 424.5 million barrels.2
Saudi Aramco's Jazan facilities came under a fresh attack on Monday (2026-09-07), according to people familiar with the matter, the National Post reported. That followed weeks of infrastructure strikes that have conditioned traders to treat conflict as a persistent supply risk rather than a series of discrete events.4
"The market is now clearly pricing in a direct military confrontation, while the prospect of a negotiated solution has diminished," said Arne Lohmann Rasmussen, chief analyst at Global Risk Management in Copenhagen.1
The East-West pipeline, linking Abqaiq on the Gulf coast to the Red Sea port of Yanbu, has served as the essential workaround to Hormuz throughout the conflict. Rigzone reported its capacity at up to 7 million barrels a day, providing a bypass for Saudi crude that would otherwise transit the strait.5
ICE Brent crude front-month settled at $89.57 on August 27 (2026-08-27), according to HDFC Sky data. By September 4 (2026-09-04), ICE Brent crude front-month had climbed above $95.52, a weekly advance of more than 7%, while NYMEX WTI crude front-month was trading near $92, up more than 10% on the week. The move from the high $80s to triple digits took barely a month.3
NYMEX WTI crude front-month held close to $101 through the week ending September 12 (2026-09-12) before Friday's (2026-09-18) session reversed course. A 1.6% single-session decline in a market that spent most of the year below $90 carries weight. The three-day losing run suggests some traders used the Saudi sales news as a prompt to trim long positions rather than as evidence of deteriorating physical demand. Settlements at $100.30 for NYMEX WTI crude front-month and $103.87 for ICE Brent crude front-month still reflect a market pricing in substantial supply disruption.5
How far Saudi Arabia extends its European sales pause, and whether tanker traffic through the Strait of Hormuz recovers from the low volumes recorded in early September, are the two data points most directly bearing on NYMEX WTI crude front-month's hold above $100 in the sessions ahead.5,2
