Aramco’s decision came days after OPEC+ opted to increase its daily crude production by 400,000 barrels a day next month. Many energy analysts doubt the group, led by Saudi Arabia and Russia, will add that much to the market because of the supply problems among some of its members. State firm Saudi Aramco increased all grades for its main market of Asia in March. The company raised its key Arab Light oil for the region by 60 cents from February to $2.80 per barrel above the benchmark it uses.
