Oil prices climbed more than 4% to their highest in more than a month on Friday after the U.S. and Iran stepped up attacks across the Gulf, with shipping threatened by a potential Red Sea closure on top of the restricted traffic through the Strait of Hormuz.
Brent crude futures settled $3.87, or 4.59%, higher to $88.10 a barrel, while U.S. West Texas Intermediate futures rose $3.54, or 4.48%, at $82.49. Both were at their highest since mid-June.
