Oil prices have surged past $100 a barrel amid the fallout of the United States and Israel’s war on Iran.

Brent crude, the international benchmark, rose more than 20 percent on Sunday, at one point topping $114 a barrel, as fears grew of prolonged disruption to global energy supplies.

After moderating slightly, the benchmark was hovering around $107.50 as of 02:30 GMT on Monday.

The surge marked the first time oil rose above $100 per barrel since Russia’s 2022 invasion of Ukraine.

US President Donald Trump, who campaigned heavily on cost-of-living concerns in the 2024 election, brushed off the spike in prices.

“Short term oil prices, which will drop rapidly when the destruction of the Iran nuclear threat is over, is a very small price to pay for U.S.A., and World, Safety and Peace,” Trump said in a post on Truth Social.

US Secretary of Energy Chris Wright also downplayed the prospect of rising energy prices earlier on Sunday, telling CBS News’ Face the Nation programme that any increase in prices at the petrol pump would be “temporary”.

Crude oil prices have surged by about 50 percent since the US and Israel launched joint strikes on Iran on February 28.

Iran has brought shipping in the Strait of Hormuz to an effective halt in retaliation, threatening about one-fifth of the global oil supply.

Iraq, the United Arab Emirates and Kuwait, three of the biggest producers in The Organization of the Petroleum Exporting Countries (OPEC), have cut production amid an accumulating backlog of barrels with nowhere to go due to the effective closure of the waterway.

Attacks on energy production facilities in the region have further threatened supplies.

Iran has been blamed for multiple attacks on energy facilities across the Gulf, including in Qatar, Saudi Arabia and Kuwait.

On Saturday, Israel carried out air strikes targeting Iran’s oil infrastructure for the first time since the start of the war.

The strikes hit four oil storage facilities and an oil production transfer centre in Tehran and the province of Alborz, according to Iranian state media.

Iran’s Revolutionary Guard Corps (IRGC) on Sunday threatened to target energy facilities across the region in retaliation, warning that oil could soar to $200 a barrel if the US and Israel “continue this game”.
