Oil Price Update: What Is Moving Crude Markets
October 8, 2026 | ATN Trade & Finance
Crude oil surged Thursday morning as two simultaneous supply threats — a spike in tanker attacks in the Strait of Hormuz and a hurricane bearing down on the US Gulf Coast — collided with already-depleted global inventories. Brent crude rose approximately 4% to around $104–105 per barrel by early Thursday, while WTI (November delivery) gained roughly 3.7–5% to approximately $91–93 per barrel.
Driver 1: Hormuz Tanker Attacks at a Conflict High
The most significant catalyst is a renewed escalation of attacks on shipping in the Strait of Hormuz. A UK Maritime Trade Operations report confirmed that a tanker was struck by multiple projectiles north of Qatar on Wednesday, with reported casualties. Vessel traffic through the strait fell to its lowest level in more than two months, according to Kpler data — a stark reversal from the partial recovery seen in September.
The Hormuz disruption is the defining supply story of 2026. Before the US-Iran conflict began in late February, roughly 20 million barrels per day of oil and petroleum products transited the strait. That flow has been fractional since the strait's closure. ANZ analyst Daniel Hynes noted Thursday that "producers now seem willing to risk vessel damage because they have no alternative route to market" — a sign that the economic pressure on exporters is intensifying even as the security situation worsens.
Adding to the geopolitical risk: media reports Thursday said the Pentagon has been directed to prepare options for resumed major US military operations against Iran, and Houthi forces separately struck a refinery in Riyadh. Neither development has yet been confirmed or denied by US officials, but both contributed to risk premium in the session.
Driver 2: Hurricane Isaias and Gulf of Mexico Shut-Ins
A second, independent supply shock materialized Thursday as Tropical Storm Isaias strengthened rapidly in the Gulf of Mexico and was expected to make landfall on the northern Gulf Coast by the weekend as a hurricane. BP, Chevron, and Shell have all begun evacuating non-essential offshore personnel. One supply model cited by Reuters estimated that up to 11.2 million barrels of cumulative Gulf of Mexico output could be lost depending on the storm's track and intensity.
Supporting Factors
US crude inventories fell 3.2 million barrels in the week ended October 2 — against market expectations of a build — leaving stockpiles with limited cushion against either disruption. The IEA announced it would accelerate the release of approximately 100 million barrels from the coordinated 400 million barrel G7 reserve program agreed in March. Prices gave back some of their early gains on the news, but analysts noted the release had largely been priced in.
Deutsche Bank analysts, cited in early Thursday coverage, said they saw little evidence that energy-linked inflation pressure is easing meaningfully — a comment that resonated with the Federal Reserve's own minutes, released Wednesday, which cited petroleum-based costs as a key upward driver of the Prices Paid index in manufacturing.
What this means for importers, logistics managers and traders: Brent above $100 is no longer a shock — it has been the operating reality for most of 2026 — but Thursday's move signals that the market has not yet fully priced in the worst-case Hormuz scenario, and that a simultaneous Gulf disruption can still move prices materially from an already-elevated base. For businesses with fuel cost exposure, hedging gaps for Q4 deserve immediate review. The IEA reserve release provides a near-term ceiling, but with the hurricane track unresolved and no diplomatic progress on the Strait, the path of least resistance for crude remains upward in the near term.
