Brent climbs 0.7% to $104.36 as Iran risk resurfaces post-midterms

Brent futures gained 76 cents, or 0.7%, to $104.36 a barrel by 0730 GMT, recovering after settling at a near four-week low in the previous session. US West Texas Intermediate rose a similar 0.7% to $96.72, also clawing back earlier losses. The move came a day after Democrats took control of both chambers of Congress in the US midterm elections, ending unified Republican control of Washington under President Trump for the remainder of his term, as the BBC's live coverage confirmed.

The mechanism is a mix of geopolitical risk and a tightening physical market. The US carried out what one official described as 'defensive' strikes on Iran's Qeshm island, targeting surface-to-air missiles aimed at US interests, though a second official said the action was limited and not a return to large-scale combat. Priyanka Sachdeva, head of market insights at Phillip Nova, said Trump's mixed signals, continued military action alongside comments playing down further escalation, had left traders without a clear direction, and flagged scope for profit-taking after October's rally. The Financial Times reported that US Vice President Vance blamed the Iran war for the scale of the Republican defeat, underlining how closely the conflict and Washington's political mood are now tied together in markets' eyes.

The chart below tracks Brent over the past six months, giving UK buyers a baseline against which this week's geopolitical premium can be judged.

What this means for UK buyers

For UK commercial energy buyers, Brent remains the reference point for oil-indexed costs and sentiment that spills into gas and power curves, even though the immediate driver here is geopolitical rather than a UK supply event. A conflict that stays contained to limited strikes is priced differently to one that threatens tanker traffic through the Strait of Hormuz, so the direction of the next fortnight's headlines matters more than the daily tick. Businesses on contracts due for renewal over the coming weeks should treat this as a volatility signal rather than a reason to panic-buy or delay.

• Risk of disruption to the Strait of Hormuz, a route for a large share of global seaborne crude
• US crude inventories falling 5.27 million barrels in the week to 30 October, against an expected build of roughly 880,000 barrels
• Gasoline stocks up 1.43 million barrels; distillate stocks down 1.19 million barrels
• Qatar's mediation efforts to prevent further escalation
• Official US Energy Information Administration data due at 1530 GMT Wednesday, which could confirm or revise the American Petroleum Institute figures

The inventory picture adds fundamental support on top of the geopolitical premium. Haitong Futures noted that diesel stocks remain tight while gasoline has built more than expected, calling the overall data supportive of oil prices. A senior Iranian official told Reuters that Tehran and Washington remain far from a deal, while Trump told the Financial Times there are no immediate plans for a further strike, a combination that keeps the market guessing rather than settling in either direction.

Watch the official EIA inventory release later Wednesday and any shift in rhetoric from Washington, Tehran or Doha: a confirmed easing of tensions would likely unwind some of this week's gains, while any sign of disruption near Hormuz would do the opposite.
