Oil prices have risen following strikes on Saudi energy infrastructure and the ongoing closure of the Strait of Hormuz. Despite a fragile truce agreed between the U.S. and Iran, concerns persist about increased tanker activity through the Strait. Brent crude futures rose by 83 cents to $96.75 a barrel as of 0100 GMT, while West Texas Intermediate futures were up by 1.06% at $98.91 a barrel. The conflict, which began on February 28, has effectively shut down the crucial artery for oil and gas flows. Some 50 infrastructure assets in the Gulf have been damaged by drone and missile strikes, and around 2.4 million bpd of oil refining capacity has been taken offline.
