On September 8, crude oil markets extended their rally as intensified military exchanges between the United States and Iran deepened concerns over prolonged supply disruptions from the Middle East. Brent crude futures rose 0.54% to settle near $96.80 per barrel, while US West Texas Intermediate (WTI) crude gained 0.72% to $92.14 per barrel. The price surge followed a volatile week in which Brent jumped 7.8% and WTI climbed approximately 10% after the US and Iran resumed attacks, leading to a tangible decline in oil flows through the region.
The official price of Oman oil for November 2026 delivery surged by $2.74 to settle at $104.54 per barrel, reflecting the acute market sensitivity to supply risks in the Gulf region. The escalating confrontation has seen commercial tankers increasingly used as instruments of mutual economic pressure, significantly eroding the distinction between military and commercial shipping.
In a closely watched Sunday meeting, the core seven members of OPEC+ (Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, and Oman) decided to keep their October 2026 production quotas flat, maintaining them at September levels. This marks the first pause in the group's monthly production increases since April. While the alliance had agreed in August to fully reverse a 1.65 million barrel per day supply cut from 2023, the ongoing war has meant that actual production remains well below these paper targets.
Analysts noted that OPEC+ currently has limited practical influence over the physical oil market, as the group can adjust production targets but cannot guarantee that barrels will be produced or actually reach buyers amidst the Strait of Hormuz blockade. The group's focus is now shifting toward a more significant debate over 2027 output baselines, with an audit of members' production capacity due to conclude later this month.
Jorge León, an analyst at Rystad Energy, observed that "the real impact will come when and if the Strait of Hormuz is fully reopened, at which point the group will abruptly transition from managing export constraints to dealing with a significant oil surplus". The next sub-group meeting is scheduled for October 4, while the full OPEC+ ministerial meeting is expected in November to discuss 2027 capacity reviews.
Prediction markets currently assign a low probability (approximately 10.5%) to oil reaching a new all-time high by December 2026, suggesting that while near-term volatility remains high, a sustained price breakout above $100 is not fully priced in.
