Crude Oil Rallies to 4‑Week High as Hormuz Chokepoint Tightens

Crude oil is trading at its highest levels in nearly four weeks as escalating Middle East tensions and reduced tanker flows through the Strait of Hormuz tighten perceived global supply, pushing Brent toward the low‑90s EUR-equivalent and WTI into the mid‑80s. Rising US crude inventories are offering only partial relief, capping the upside but not preventing a risk‑premium from rebuilding. The renewed rally is being driven by a sharp slowdown in Hormuz transit volumes, additional export disruptions from Russia’s Black Sea terminals and exceptionally strong US refinery demand that is drawing on available crude. The UAE’s suspension of financial and economic ties with Iran and the absence of any clear diplomatic path from Washington keep headline risk elevated. Near term, the market remains highly sensitive to further shipping disruptions or signs that inventories can no longer absorb the shock.

Prices

Brent crude futures settled at USD 91.62 per barrel (roughly EUR 84–85), up 0.7% on the day and marking the strongest close since July 24. US WTI ended at USD 85.83 (around EUR 79–80), gaining 1.1% and also reaching a four‑week high.

The latest move extends a multi‑session advance fuelled by geopolitical headlines and physical bottlenecks around the Strait of Hormuz. Although prompt time spreads are not detailed, the price structure is consistent with firmer backwardation, reflecting a growing near‑term supply risk premium rather than purely demand‑led strength.

Supply & Demand

Transit through the Strait of Hormuz has slowed sharply, with only six commodity vessels reported crossing on Tuesday, down from nine the previous day and well below the recent daily average of 11. Before the conflict, roughly one‑fifth of global crude and LNG flows transited this route, underlining the systemic impact of any prolonged disruption.

Geopolitical risk has intensified after the United Arab Emirates suspended all financial and economic transactions with Iran following renewed missile attacks, amplifying uncertainty around regional logistics and financing channels. Diplomatic visibility remains poor: Washington insists the strait is open yet reports of minimal tanker movement and Iran’s claim that the waterway is closed reinforce market fears of de‑facto restrictions on flows.

Beyond the Gulf, Russian crude exports from western ports have fallen to around 2.3 million barrels per day in the first half of August, about 15% below the original loading program due to disruptions at Novorossiysk. This compounds the Hormuz‑related tightness by limiting alternative barrels, particularly for European and Mediterranean refiners.

Fundamentals

Refining demand is notably robust. US refinery utilization has climbed by one percentage point to a very high 97.2%, signalling strong margins and tight product markets that encourage maximal crude runs. This keeps competition for seaborne barrels elevated even as freight and route risks increase.

At the same time, US commercial crude inventories have risen by 4.4 million barrels to 428.8 million barrels in the latest reporting week. This stock build provides a counterweight to the bullish narrative by indicating that, for now, domestic US supply is ample enough to absorb some of the external shock, tempering fears of immediate physical shortages.

The juxtaposition of strong runs and rising stocks suggests that logistical and regional imbalances, rather than absolute global scarcity, are currently driving the risk premium. Any shift toward sustained draws in US stocks would be interpreted as confirmation that the Hormuz and Black Sea disruptions are materially tightening global balances.

Outlook & Trading View

With no negotiations planned between the US and Iran and the UAE–Iran rift deepening, the geopolitical risk premium is likely to remain embedded in prices. The key near‑term swing factors are the pace of tanker movements through Hormuz, the duration of Russian export disruptions and whether US inventory builds persist or flip into draws.

• Producers/hedgers: Current levels near four‑week highs offer an opportunity to layer in incremental hedges for Q4, while keeping some upside open given the potential for further escalation.
• Consumers/importers: Consider securing a portion of physical needs or hedges on dips, as downside appears limited while Hormuz flows remain constrained and Russian exports disrupted.
• Short‑term traders: Market is headline‑driven; favor buying pullbacks toward recent support rather than chasing breakouts, with tight risk management around geopolitical news flow.

Over the next three sessions, Brent in EUR terms is likely to trade with an upward bias within the mid‑80s to high‑80s per barrel range, while WTI in EUR is expected to oscillate in the upper‑70s to mid‑80s range, with intraday direction dominated by updates on Hormuz shipping activity and US inventory signals.
