Oil prices surged 3.4% to $91.09 a barrel on Monday due to renewed fighting between the US and Iran, with Brent crude prices increasing and American crude prices also rising by a similar amount. According to experts, the hostilities have increased fears of supply disruptions caused by tanker traffic curtailment in the Strait of Hormuz. The average price of regular unleaded gasoline in the US remained relatively flat at 4.08 gallons, while diesel prices decreased slightly. The developments come as the US Strategic Petroleum Reserve has fallen to its lowest level since 1982.
