Oil Markets – Brent Crude Rises as US-Iran Tensions Renew Supply Concerns
Oil Markets – Brent crude oil prices moved higher on Thursday after fresh US military action involving Iran intensified concerns about possible disruptions to energy supplies from the Middle East. Traders reacted to the renewed geopolitical uncertainty, pushing benchmark prices close to USD 79 a barrel during the session.

Brent crude was trading at USD 78.68 per barrel at the time of reporting, an increase of 0.95 per cent, or USD 0.74, from the previous close of USD 78.02. The contract reached an intraday high of USD 79.15. West Texas Intermediate crude also advanced, rising 0.92 per cent, or USD 0.68, to USD 74.22 per barrel.
Futures markets react to overnight developments
Oil futures had already gained more than USD 1 in after-hours trading on Wednesday following reports that US forces had launched another series of strikes on Iran. The move added to market anxiety over the security of oil production and transport routes in a region that remains central to global crude supplies.
Investors are closely monitoring whether the latest escalation could affect shipments through key waterways or prompt wider regional instability. Even without an immediate interruption to production, concerns about supply security can quickly influence crude futures, particularly when military developments involve major oil-producing areas.
Wall Street closes with mixed results
US equity markets finished Wednesday on an uneven note as developments in the Middle East unsettled investors. President Donald Trump told a NATO summit in Turkey that the ceasefire with Iran was “over,” raising fresh questions about the direction of the conflict and the possibility of further military action.
The Dow Jones Industrial Average fell 576.76 points, or 1.09 per cent, to close at 52,348.39. The S&P 500 declined 0.28 per cent to 7,482.71. The Nasdaq Composite, however, recorded a modest gain of 0.2 per cent and ended the session at 25,870.65.
The different market performance reflected a cautious response from investors. Higher oil prices can increase inflation concerns and add pressure to businesses dependent on fuel and transport costs, while technology shares showed relatively more resilience during the session.
Brent and WTI post strong gains
At Wednesday’s settlement, Brent crude had climbed 5.43 per cent to USD 78.19 a barrel. WTI gained 4.37 per cent to settle at USD 73.52. The sharp increase followed renewed fears that the conflict could threaten oil flows or create broader disruption across the region.
Analysts often view crude prices as highly sensitive to political and military developments in the Middle East because the area accounts for a substantial share of global oil output. Any signs of escalating confrontation can lead traders to factor a higher risk premium into prices.
US signals further action may be possible
US Central Command said American forces carried out fresh strikes on Iran on Wednesday night. The announcement came hours after Trump declared the end of the eight-week ceasefire.
Trump also indicated that Washington could consider additional military action against Iran. Referring to attacks carried out on Tuesday, he said the United States had struck Tehran “very hard” and suggested further steps could follow.
During his remarks, Trump accused Iranian leaders of changing their position in negotiations. He claimed that Iranian officials had indicated privately that they were open to an agreement before making different public statements.
“They’ll agree on everything, and then they’ll go and have a news conference and say we never even talked about it,” Trump said.
