Oil prices settled about 1 per cent lower on Thursday even as the Iran war escalated, with the Middle East oil producer asking Yemen’s Houthi movement to be prepared to close the Red Sea oil export route.
Brent crude futures fell by 72 cents or about 0.9 per cent to trade at $84.23 a barrel, while the US West Texas Intermediate (WTI) futures depreciated by 65 cents or 0.8 per cent to close at $78.95 a barrel.
Iran has instructed Yemen’s Houthi movement to stand ready to close the Bab el-Mandeb strait, the vital gateway to the Red Sea, if the US follows through on threats to strike Iranian power infrastructure.
Market analysts warned that with the Strait of Hormuz already closed, the latest threat raises the serious risk of both of the Middle East’s primary oil export routes being disrupted at the same time.
About 7.4 million barrels of petroleum transited Bab el-Mandeb per day in June, about 7 per cent of global oil output, according to Kpler data, up from 4.2 million barrels per day last year.
This week, US President Donald Trump repeated oft-stated threats to strike Iranian power plants and bridges.
According to senior Iranian sources, the Islamic Republic’s leadership has discussed the idea with Iran’s Houthi allies, with the rebel forces now awaiting definitive orders to begin targeting maritime traffic.
In a sign of escalating tensions in the region, the Houthis fired missiles at Saudi Arabia after accusing the kingdom of bombing an airport under their control on Monday, breaking a four-year truce in the conflict between the kingdom and the group.
This comes as Saudi Arabia is currently evaluating a massive infrastructure expansion to permanently upgrade the capacity of its western pipeline and terminal networks.
Any additional disruptions could force international shipping firms to redirect vessels around Africa, inflating transit costs and worsening the global energy crisis.
On Wednesday, the US struck Iran’s coastal defences and missile sites after reimposing a naval blockade of its ports, while the two countries exchanged intensified fire on Thursday, which kept pressure on prices upward.
However, weighing on prices was Iran’s release of a US citizen, which could point toward a path to avert the resumption of all-out war.
