Oil prices jumped 3% on Monday, with Brent surpassing $90 a barrel, as the United States and ​Iran expanded attacks in the Middle East that have curbed energy shipments ‌in the Strait of Hormuz.Brent crude futures climbed $2.69, or 3.05%, to $90.79 by 2343 GMT, touching the highest since June 11, extending gains after rising 15.9% last week, its ​biggest weekly gain since April.U.S. West Texas Intermediate crude was at $84.68 ​a barrel, up $2.19, or 2.65%, the loftiest since June 12.Front-month prices gained 15.5% last week, the largest weekly ascent since early ​March.The Middle East conflict escalated over the weekend with the U.S. conducting a ninth ​straight night of attacks against Iran, while U.S. allies Kuwait and Bahrain reported more Iranian strikes.In recent days both sides have taken aim at shipping traffic, with the U.S. ​saying it is enforcing a naval blockade on Iranian ports, and Iran ​saying it targets vessels violating its rules on navigating the Strait of Hormuz, which usually ‌handles ⁠one-fifth of global oil trade.A vessel was on fire northwest of Oman's Kumzar, the United Kingdom Maritime Trade Operations agency said early on Monday."The coming days and weeks will provide a clearer picture of the sustainable level of oil ​exports from the ​region under renewed ⁠dual blockades," Barclays analyst Amarpreet Singh said in a note."As things stand, we think oil markets are still too ​complacent about the potential fallout for inventories, which, unlike ​at the ⁠beginning of the war, are at the tightest of the past five years."Four vessels made the transit through the Strait of Hormuz on Sunday, down from eight ⁠in the ​previous day, LSEG data showed. At least ​three oil products tankers and one Very Large Crude Carrier, have entered the strait since Friday ​to load oil, the data showed.Source: Reuters-Agencies
