Saudi Arabia increased prices for some crude exports by the most in at least two decades, doubling down on a strategy to bolster the oil market after OPEC+ producers extended historic output cuts over the weekend. The steepest jump in July exports will hit buyers in Asia, state producer Saudi Aramco’s largest market, according to a pricing list from the company on Sunday. The increases erase almost all of the discounts the kingdom made during its price war with Russia earlier this year.

Still, oil refiners’ profits are being squeezed by crude’s rally, and the sharp Saudi hikes are likely to exacerbate that problem. Representatives for refineries from Europe and Asia expressed concern and said the new pricing would crush their margins.

Price War

The month-on-month increase in the official selling price for flagship Arab Light crude to Asia, which accounts for more than half of Saudi oil sales, is the largest in at least 20 years. Aramco raised Asian Arab Light by $6.10 a barrel from June to a premium of 20 cents over the benchmark.
