Brent crude climbed to $91.87 a barrel on Thursday – its fifth consecutive session of gains – as a stalled U.S.-Iran conflict and suppressed Strait of Hormuz traffic kept global supply concerns firmly in focus.
With peace talks deadlocked and the UAE severing financial ties with Tehran, energy investors face an extended period of elevated crude prices that could ripple through fuel costs, refining margins, and distillate-dependent industries worldwide.
Key Takeaways
- Brent and WTI mark a fifth straight session of gains.
- Hormuz shipping flows remain far below pre-war levels.
- UAE suspends all financial and economic ties with Iran.
Market Reaction & Context
Brent crude futures for October delivery rose 26 cents, or 0.28%, to $91.87 a barrel by 0439 GMT on Thursday, while U.S. West Texas Intermediate (WTI) futures for September added 17 cents to $86.00 a barrel 1. The more actively traded October WTI contract gained 12 cents, or 0.13%, to $89.91 – with both benchmarks settling Wednesday at their highest levels since July 24.
The five-session winning streak places crude meaningfully above where it traded before the latest round of geopolitical friction intensified. Prior to the U.S.-Israeli military campaign against Iran, which began on Feb. 28, shipments equal to roughly one-fifth of global oil consumption moved through the Strait of Hormuz; current flows remain far below that baseline, according to the latest shipping data 1.

Detailed Analysis: Supply Squeeze and Diplomatic Impasse
The core driver of Thursday’s price support is a war-induced reduction in Middle Eastern crude output and refinery feedstock availability. The conflict has drawn down inventories of refined fuels, with U.S. distillate stocks – including diesel and heating oil – falling for a third consecutive week, according to the Energy Information Administration (EIA) 1.
That tightness in distillates stands in contrast to a 4.4-million-barrel build in U.S. crude inventories for the week ended Aug. 14, which came in well above analyst estimates of a 600,000-barrel draw – a figure that would normally weigh on prices but was overshadowed by geopolitical risk premium 1.
On the diplomatic front, President Donald Trump said on Tuesday that no talks were underway with Iran and maintained the Strait of Hormuz was open. Tehran, however, insisted the waterway remained shut – a contradiction that shipping data has not fully resolved, with traffic on Wednesday unchanged from the prior day 1.
Adding a new layer of complexity, the UAE announced a suspension of all financial and economic transactions with Iran until further notice, refocusing market attention on strained Gulf Arab-Iranian relations. The move raises concerns about broader regional economic fragmentation at a moment when the Strait remains a critical chokepoint – a dynamic explored in our earlier coverage of Crude Prices Dip Amid Chokepoint Clearance.
Analyst View
“Oil prices remained elevated as the market is supported by sporadic attacks in the Middle East but lacks fresh momentum without a major escalation,” said Hiroyuki Kikukawa, chief strategist of Nissan Securities Investment, a unit of Nissan Securities 1.
Kikukawa added that “the market is likely to maintain a gradual upward trend given uncertainty over peace talks and tensions involving the United Arab Emirates, Oman and Iran” – flagging Oman as a secondary flashpoint after reports that Trump threatened consequences if Muscat interfered with a potential Iran deal 1.
Outlook
With the September WTI contract expiring Thursday and the October contract now the market’s focal point, near-term price direction hinges almost entirely on whether diplomatic channels reopen or the military standoff deepens. Analysts are watching for any shift in UAE-Iran relations, movement in Hormuz traffic data, and whether distillate inventories continue their three-week decline.
The inventory crosscurrents – rising crude stockpiles but tightening refined-product supplies – suggest that even a partial easing of Hormuz disruptions may not immediately translate into lower pump prices for end consumers. Energy investors tracking refinery throughput and crack spreads may find the distillate shortage the more actionable near-term signal.
Conclusion
Thursday’s modest but persistent oil price gains illustrate a market caught between a lack of dramatic new escalation and an absence of credible peace momentum. Until Hormuz shipping normalises or diplomacy produces a verifiable breakthrough, the supply-risk premium looks likely to keep both Brent and WTI elevated relative to pre-war levels.
