Oil prices jumped 3 per cent on Wednesday as mounting supply concerns following escalating hostilities between the United States and Iran, while threats to shipping by the Iran-backed Houthi militia in Yemen further boosted prices.
Brent crude futures went up by $3.06 or 3.36 per cent to $94.07 a barrel, while the US West Texas Intermediate crude climbed $2.49 or 2.95 per cent to $86.83 a barrel.
The US military said it carried out an 11th consecutive night of attacks on Iran. The US attacks came a short while after the Kuwaiti army said its air defences were intercepting Iranian drones.
President Donald Trump said on Wednesday the US would “bomb and destroy one bridge or power plant” any time Iran targets a ship in the Strait of Hormuz.
Iran’s Revolutionary Guards’ spokesperson warned shipping companies that the Strait of Hormuz southern route is mined.
As well as the renewed conflict over control of that key waterway, the Iran-aligned Houthis have opened a new front in the war by threatening to target vessels carrying Saudi oil in the Bab el-Mandeb Strait and announced a naval blockade of Saudi Arabia.
Bab el-Mandeb at the southern entrance to the Red Sea has become an increasingly important route for Saudi Arabian crude exports as traffic through the Strait of Hormuz has fallen sharply again since a ceasefire between the US and Iran collapsed earlier this month.
Five tankers in the Red Sea avoided the Bab el-Mandeb Strait on Wednesday after the Houthis’ threat to block Saudi oil exports.
The European Union’s naval force Aspides said on Wednesday that ships with links to Israel, the US or Saudi Arabia are at a higher risk of being attacked by Yemen’s Iran-aligned Houthi militia and are advised to avoid voyages through the Red Sea and Gulf of Aden.
Crude oil inventories in the US saw an increase of 2.0 million barrels during the week ending July 17, according to new data from the US Energy Information Administration (EIA) released on Wednesday.
It follows figures by the American Petroleum Institute (API) that were released a day earlier, which reported that crude oil inventories had risen by 2.603 million barrels in the period.
The increase brings commercial stockpiles to 411.7 million barrels, according to government data, which are now 6 per cent below the five-year average for this time of year.
Meanwhile, European Union (EU) ambassadors failed on Wednesday to agree on a 21st package of sanctions against Russia over its invasion of Ukraine in 2022.
