Baghdad: Oil prices rose to a four-week high on Tuesday as the United States reimposed its naval blockade on Iran, increasing uncertainty about energy flows. Brent crude futures rose $1.68, or 2%, to $84.98 a barrel by 00:51 GMT, while U.S. West Texas Intermediate crude gained $1.65, or 2.1%, to $79.79 a barrel. According to National Iraqi News Agency, Brent crude experienced a significant jump of 9.6% in the previous session, marking its largest daily gain since May 2020. The reimplementation of the U.S. naval blockade has heightened tensions in the region, causing fluctuations in the oil market. The strategic Strait of Hormuz is a critical passageway for global oil transportation, and any disruptions in this region can have widespread impacts on oil prices.
