Oil Prices Surge on Renewed US-Iran Tensions
Oil prices climbed in early Asian trading on Monday after fresh military exchanges between the United States and Iran raised concerns about crude supplies through the Strait of Hormuz. West Texas Intermediate front-month futures rose 2.47% to $85.46 a barrel, while Brent gained 2.71% to $90.49, according to figures reported by the Bangkok Post.
The increase followed a US strike on two Iranian Revolutionary Guard rocket launchers on Larak Island, located within the strategically important Strait of Hormuz. The US Central Command said the strike targeted Iranian Revolutionary Guard forces that were preparing to launch rockets and deploy sea mines in the waterway. The action came shortly after US President Donald Trump said Washington had completed mine-clearing operations in the strait and warned against further attempts to obstruct shipping, as reported by the Free Press Journal and the Bangkok Post.
Iranian Retaliation and Regional Impact
Iran responded by launching ballistic missiles and drones towards US military facilities in Jordan. Jordanian authorities said their air defences intercepted eight missiles that entered the country's airspace. Iran's Revolutionary Guard subsequently said it had targeted infrastructure and aircraft positions at two US bases in Jordan, the Free Press Journal reported.
The attacks followed a US announcement on Sunday that it had struck Iranian rocket launchers in the Strait of Hormuz, marking the first US strikes on Iran in a month, according to the Bangkok Post. President Trump said Monday that the United States would hit back against Iranian attacks on US targets in the Middle East, the Bangkok Post reported, citing Fox News.
The latest exchange came shortly after the US-Iran conflict reached the six-month mark, at a time when hostilities had been subsiding. The developments revived concerns about whether the confrontation would remain limited or trigger broader disruption to Gulf energy exports.
Market Reactions and Shipping Disruptions
Brent's return above $90 a barrel marks a significant move, although prices remain below levels reached during earlier stages of the conflict. Both benchmarks had fallen more than 4% last week, the Bangkok Post noted.
Meanwhile, commercial shipping through the Strait of Hormuz remains substantially below pre-war levels. Vessel traffic reportedly fell to around five ships a day over the weekend, while a maritime warning said another tanker had been hit by an unidentified projectile. The United States has also continued its blockade of Iranian ports, with 83 commercial vessels reportedly redirected and several others disabled or boarded as of August 30, according to the Free Press Journal.
"For oil traders, (the) move is another reminder of how quickly the geopolitical premium can return," said Stephen Innes, an analyst at Quintex Intelligence, as quoted by the Bangkok Post. "Physical flows through Hormuz have improved materially from their worst levels, which is precisely why crude had started giving back some of the fear premium, but the latest exchange shows how fragile that progress remains and how quickly the shipping story can be pushed back onto the trading desk," he added.
Economic and Market Context
With inflation remaining stubbornly high, largely driven by elevated energy costs, the US Federal Reserve has come under pressure to act. Federal Reserve chief Kevin Warsh's refusal to provide guidance has stoked uncertainty in recent weeks, the Bangkok Post reported. In a highly anticipated speech at the Jackson Hole symposium of central bankers and economists in Wyoming on Friday, Warsh left traders with few doubts that he was ready to increase interest rates, the outlet said.
The renewed oil price spike coincided with mixed stock market performance globally. Wall Street dipped as investors reacted to Warsh's hawkish comments, while European markets were mixed: Paris rose, Frankfurt fell, and London was closed for a holiday. In Asia, Tokyo's Nikkei and Hong Kong's Hang Seng declined, while Shanghai gained, according to the Bangkok Post.
Key economic data releases expected in the coming week include US jobs figures and the consumer price index, which could influence market sentiment. Patrick O'Hare, an analyst at com, was quoted by the Bangkok Post as saying that investors were closely watching the data for signs of how inflation and the labour market were evolving.
Outlook
Traders are now weighing the latest military exchanges against improving physical flows through the Strait of Hormuz. While the geopolitical premium has returned sharply, the long-term trajectory of oil prices will depend on whether the conflict expands and whether shipping disruptions persist. The coming days are likely to bring further clarity as economic data and geopolitical developments unfold.
