Saudi oil shock ripples across Asia

Saudi Arabia has raised the official selling price of its flagship Arab Light crude for Asian buyers to a record premium for May-loading cargoes, a move that underscores how sharply Middle East supply risks have altered energy markets and procurement strategies across the region. The increase follows weeks of disruption around the Strait of Hormuz, the main route for Gulf crude exports, and comes as refiners from South Korea to China and other large importers scramble to secure alternative barrels and shipping routes.

The pricing move appears to confirm what traders had been bracing for since the start of April. A Reuters survey published on April 1 said Saudi Arabia was likely to raise May crude prices to Asia to record highs, with forecasts for Arab Light ranging from $22.50 to $40.50 a barrel above the Oman-Dubai benchmark, reflecting exceptional volatility in sour crude markets. Separate reporting published on April 6 said Aramco had set Arab Light for Asia at a record premium of $19.50 a barrel, lower than some of the most extreme trade forecasts but still above previous highs.

That matters because Saudi official selling prices are more than a commercial detail. They serve as a reference point for refiners across Asia and signal how Riyadh reads the balance between physical supply, benchmark strength and regional demand. The latest jump comes after the Dubai cash premium to swaps averaged $38.30 a barrel in March, up from 90 cents in February, according to Reuters data cited in the survey. Saudi Aramco uses such market structure signals when setting monthly prices, and the scale of the increase shows how severely physical availability has tightened.

At the centre of the squeeze is the Strait of Hormuz. The U. S. Energy Information Administration said oil flow through the waterway averaged 20 million barrels a day in 2024, equivalent to about 20% of global petroleum liquids consumption, while Saudi Arabia alone accounted for 38% of crude and condensate flows through the strait, or about 5.5 million barrels a day. Although Saudi Arabia and the United Arab Emirates have pipelines that can bypass Hormuz, available spare bypass capacity is limited, which helps explain why any prolonged disruption swiftly feeds into pricing.

Saudi Aramco has already been forced to reshape its export pattern. Reuters reported on March 23 that the company cut crude supply to Asian buyers for a second month in April and shifted deliveries to Arab Light loaded from Yanbu on the Red Sea, rather than from the Gulf. Aramco said at the time it was using alternative export routes through Yanbu to maintain reliable supply. Chief executive Amin Nasser later warned that a continued blockage would have “catastrophic consequences” for oil markets, describing the situation as the biggest crisis the region’s oil and gas industry had faced.

The broader market backdrop has turned even more strained. Reuters reported on April 5 that OPEC+ agreed to raise May output quotas by 206,000 barrels a day, but analysts and officials said the increase would largely exist on paper because the producers with the most spare capacity are also those hit hardest by the Hormuz disruption. Reuters further reported that the conflict has already removed an estimated 12 million to 15 million barrels a day from the market, while the International Energy Agency said in March that the war had created the largest supply disruption in oil market history and prompted member countries to release 400 million barrels from emergency reserves.

For Asia, the Saudi pricing decision is both a cost shock and a warning about supply security. South Korean President Lee Jae Myung said on April 6 that Seoul had to balance risk because a full cut-off of Middle East shipments would pose a serious threat to crude supply. Reuters reported that officials in Seoul were consulting Saudi Arabia, Oman and Algeria on alternative routes and barrels, while considering the use of strategic reserves and Red Sea shipping options. Similar concerns are rippling through the wider region as refiners weigh whether to pay up for Middle East crude, bid for Atlantic Basin grades or trim refinery runs.
