Oil climbs as US-Iran tensions rattle markets

Brent crude futures (UKOIL) rose to $96.89 per barrel on June 3, 2026, marking a third consecutive session of gains and taking prices toward $97. The advance followed a roughly 1% rise on June 2, when oil reached a one-week high. Trading was volatile as investors reacted to developments in the conflict involving the United States and Iran alongside signs of tightening supply.

Market participants weighed the latest geopolitical headlines against data from the oil industry, which pointed to a substantial drawdown in US crude inventories. The combination of heightened political risk and evidence of firmer demand or constrained supply supported a higher risk premium in crude prices.

The US Central Command said Iran launched ballistic missiles toward neighboring countries, reinforcing investor concern about potential disruptions in the key oil-producing region. In the same statement, US forces were reported to have carried out strikes on Qeshm Island, adding to perceptions of an unstable security environment.

These military developments unfolded as markets were already sensitive to any sign of escalation. The reports helped push oil higher as traders reassessed the likelihood of further supply risks, even as diplomatic channels between Washington and Tehran remained active.

Alongside the military activity, diplomatic efforts continued. On June 2, oil prices moved higher as markets awaited news that Tehran was reviewing a US proposal to halt the conflict. The prospect of progress on a framework agreement became a key factor driving intraday swings in energy prices.

US officials, including President Donald Trump, said negotiations with Iran remained active. Trump said Washington was seeking written commitments from Tehran as part of a preliminary framework. The combination of ongoing talks and intermittent hostilities created uncertainty over the outlook for regional stability and oil flows.

Industry data showed that US crude inventories fell by 6.8 million barrels in the most recent weekly report. The drawdown suggested a tightening balance in the oil market and provided fundamental support to prices already buoyed by geopolitical concerns.

The inventory figures reinforced the view among traders that supply-demand conditions were improving for producers. Coupled with the elevated geopolitical risk premium, the data helped sustain Brent’s (UKOIL) climb over the past three sessions.

Rising oil prices and the unresolved US-Iran standoff fed into broader market sentiment. Headlines highlighted that Wall Street futures were pausing near record highs as oil advanced in the face of a Middle East stalemate, while some European and Gulf equity markets showed pressure linked to regional tensions and private market concerns.

Other market coverage noted that gold prices fell even as US-Iran hostilities pushed oil higher, underscoring shifting investor preferences across asset classes. In parallel, reports pointed to most Gulf markets retreating on war-related jitters, and to oil jumping more than 1% as talks between Iran and the United States were described as stalled or strained.
