Singapore: Bunker fuel sales at UAE's Fujairah port ​in the first half of ​2026 more than halved versus last year, after the ​U.S.-Iran war hit supplies at the key Middle Eastern ship refuelling hub located near the Strait of Hormuz.The sharp decline has further eroded Fujairah's lead among the world's top ‌bunkering hubs. ⁠China's ⁠Zhoushan port now appears poised to steadily overtake it this year as the world's third-largest ​hub, with supply disruptions continuing to weigh. Marine fuel sales, excluding lubricants, totalled about ​1.63 metric tons (10.4 million barrels) in the first half of 2026 at Fujairah, down 55% from the first half of 2025, based on Fujairah ​Oil Industry Zone data published by S&P ⁠Global.Also Read: DP World Plans UAE East Coast Port to Bypass Strait of HormuzMonthly volumes ‌extended declines, hitting a fresh low in June at ​about 86,000 ​tons.Low-sulphur marine fuel sales, including both residual fuels and gasoil ⁠fuels, made up 51% of June volumes, while high-sulphur ​marine fuel sales comprised the other 49%. Sales first ​crashed in March after the war broke out at the end of February, effectively shutting the waterway, and infrastructure was attacked, which hampered loading operations.The Fujairah port typically imports fuel oil cargoes from other Middle Eastern exporters such as Iran, as well as from Russia.Most supplies ‌from Middle Eastern exporters usually exit via the strait. Fuel oil supplies from Russia have also declined month-on-month into 2026 so ​far, after ​Ukraine ramped up ⁠infrastructure attacks on Russian refineries.Also Read: Iran war: India calls Fujairah attack 'unacceptable'; demands immediate cessation of hostilitiesThe lower supplies tightened the Fujairah market. While replenishment emerged in early July after a short-lived U.S.-Iran ceasefire, market sources said that ​supply streams remained uncertain again amid a return to hostilities.Residual fuel oil inventories at Fujairah rebounded to above 7.3 million barrels (1.2 million tons) in the week to July 6, the highest since early March, Fujairah Oil Industry Zone data showed. However, stockpiles eased slightly again this week.
