Oil price rises above $117 a barrel amid fears US will renew strikes on Iran

Brent crude increase follows Tehran threatening retaliatory attacks on Gulf refineries and datacentres

Oil has hit its highest level in more than five months as fears of fresh escalation in the Middle East conflict grip the energy markets.

Brent crude, the international benchmark for oil, rose by 1% on Friday morning to above $115 a barrel – its highest level since May.

The increase came after Tehran said it would attack oil facilities, undersea cables, datacentres and AI facilities in the Gulf region if a new US-Israeli offensive was launched against Iran .

Richard Hunter, of the broker Interactive Investor, said: “Widespread reports that the US is considering renewed military strikes on Iran after the midterm elections rather than pursuing a diplomatic route was enough for the price to pop, after what many had considered would be a brief conflict is now in its eighth month.”

Oil had traded at about $72 a barrel back in February, before the Iran war began, but soared to $126 a barrel by the end of April.

Tensions in the region have been rising this week and Iran’s Islamic Revolutionary Guards Corps claimed to have struck four commercial ships in the strait of Hormuz on Wednesday. The US state department ordered some diplomats and the families of US government employees to leave Saudi Arabia , which has faced continued attacks from Houthi rebels in Yemen.

Susannah Streeter, the chief investment strategist at the broker Wealth Club, said fears were rising that American and Israeli forces would be ordered to launch strikes on Iran’s energy infrastructure after the US elections on 3 November.

She added: “At the same time, the attacks on Saudi Arabia’s facilities by Houthi rebels have intensified this week, and for ships attempting to cross the strait of Hormuz, it’s still a dangerous journey, with projectiles still being fired.”

Streeter said Ukraine’s bombardment of Russian diesel refineries was also adding to supply concerns.
