Crude oil prices surged over $2 during Monday's morning deals after Saudi Arabia sharply increased rates for its crude sales in July. The move signals the continuation of tight supply even after OPEC+ agreed to improve its output during the upcoming two months. Brent crude futures increased by $1.80, or 1.5%, at $121.52 a barrel at 2319 GMT after touching an intraday high of $121.95.
