Saudi Arabia has cut its November official selling prices (OSPs) for crude loading to Asian buyers to their lowest level in six years, according to a report by Egypt Oil & Gas.

The reduction applies to the kingdom's price formula for Asia — its largest export market — for cargoes loading in November 2025. A six-year low means Asian refiners are now seeing the weakest Saudi pricing differential since 2019, a period that preceded the demand collapse of 2020 and the price shock that followed.

State producer Saudi Aramco sets OSPs monthly, basing them on a formula tied to regional benchmark grades and customer feedback. Asia's OSPs track the Oman/Dubai average. The monthly announcement is watched closely across the trading desks of Singapore, Tokyo, Seoul and Mumbai because it anchors pricing for millions of barrels per day of Middle East crude flowing East of Suez.

What does the cut signal?

The move to multi-year lows signals that the world's largest crude exporter is working to defend market share in Asia at a moment when competing supplies are plentiful and refining margins in the region remain under pressure.

Traders typically read a deeper-than-expected OSP cut in two ways:

• Demand-side softness: Asian refinery runs and margins have not supported aggressive crude purchases, giving buyers leverage in the monthly price-setting process.
• Supply competition: Grades from the Atlantic Basin, West Africa and rising output elsewhere have intensified competition for Asian refinery slots, pushing the benchmark-tracking differential lower.

Saudi Arabia has historically used OSPs as a throttle — trimming differentials when it wants to keep cargoes moving into Asia, and lifting them when the market tightens. A six-year low marks the aggressive end of that throttle range, at least as far as the published differential level indicates.

How do OSPs reach the market?

Official selling prices do not set spot crude prices directly. Instead, they translate benchmark moves into contract terms:

• Aramco publishes differentials for each grade — Arab Light, Arab Medium, Arab Heavy and Arab Extra Light — against the regional benchmark for each destination region.
• Asian buyers lifting term volumes pay the benchmark average plus or minus that differential.
• A lower differential means cheaper crude relative to the floating benchmark, which either reflects or stimulates spot demand depending on the month.

The November cut follows the kingdom's monthly pricing cycle, with Aramco typically releasing OSPs in the first week of the preceding month. The differentials for Europe and the US are published on the same schedule.

Why does a six-year low matter now?

The level is the story. Pricing differentials at their weakest since 2019 indicate sustained pressure on the physical crude market East of Suez — pressure that benchmarks themselves, influenced by financial flows and forward curves, do not always show as clearly.

For Asian refiners, softer OSPs feed straight into procurement economics. A lower differential on term cargoes improves crude acquisition costs relative to product yields, a direct input to refinery margins at complexes from Jamnagar to Ningbo. Aramco's Asian customers lift a substantial share of the kingdom's roughly 9 million bpd-plus crude exports under term contracts, so even modest differential moves carry real cash value across the book.

For competing producers — Iraq, Kuwait, the UAE, Iran's indirect barrels, plus Atlantic Basin and US grades seeking Asian homes — a cheaper Saudi OSP forces a pricing response if they want to hold allocation. That competitive cascade is the mechanism through which one producer's formula adjustment moves the wider spot market.

What is the watch item?

The next data point is the December OSP release, expected in early November. Traders will look for whether November's six-year low marks a floor or the start of a deeper discounting cycle. Second, watch OPEC+ production policy decisions in the same window: several members, including Saudi Arabia, hold spare capacity, and pricing aggression can accompany volume strategy — or substitute for it.

Third, watch Asian refinery margins and run rates through the fourth quarter. If cracking economics improve, demand for term barrels firms and OSPs stabilize. If they do not, December differentials could plumb further depths.
