Oil prices rose on Friday, with Brent crude futures up 0.2% at $95.67 a barrel and U.S. West Texas Intermediate futures 0.3% higher at $91.56. Brent was set to gain 7.1% for the week and WTI 9.8%, their strongest weekly advances since the week ended July 20, as renewed U.S.-Iran hostilities raised concerns about Middle East supply disruptions. The escalation included U.S. attacks that killed and wounded dozens, including Iranian civilians, while Israel Defence Minister Israel Katz warned Israel would "cripple" Iran's military and civilian infrastructure, including energy facilities. U.S. Vice President JD Vance said Washington would not negotiate with Iran unless Tehran stopped attacking commercial shipping in the Strait of Hormuz. Gains were limited after Russian President Vladimir Putin said a deal to end the war in Ukraine remained possible, with U.S. and Chinese support for a peace settlement. Iran also expanded the list of vessels subject to fines, confiscation or detention for attempting to transit Hormuz, while Iraqi exports rose to about 2.34 million barrels per day in August from 1.35 million bpd in July.
