Asian Refiners Are Bidding Up Murban While Sitting on Three Months of ADNOC Supply
A $30 spot premium over Dubai looks less like a shortage signal and more like positioning anxiety layered on top of already-full Asian tanks.
Indian and Chinese refiners stepped up spot purchases of Middle Eastern crude in early September (2026-09-03), pushing differentials to levels not seen since the height of the Hormuz crisis, traders said. Abu Dhabi's Murban now commands a premium of more than $30 a barrel over Dubai for East Asia delivery. Dubai crude stood at $98.71 a barrel as of September 8, which puts implied Murban delivered east of Suez above $128 a barrel — substantially above ICE Brent front-month at $97.78 a barrel recorded in the same session.6
The same refiners bidding aggressively for spot barrels on September 8 absorbed an extraordinary volume of ADNOC crude over the preceding three months. Since June, ADNOC has sold at least 94 million barrels via seven tenders for delivery through October, according to a Reuters tally, with total sales across all grades reaching around 110 million barrels. Indian refiners took roughly 6 million barrels from ADNOC's emergency program alone. Japan's Eneos bought 3 million barrels. SK Energy and GS Energy in South Korea secured another 8 million barrels between them.5,2,4
June Goh, senior oil market analyst at Sparta Commodities, said refineries in the East "have already been well-supplied for the next two months and have little immediate appetite for incremental barrels." That assessment was made on Friday (2026-06-26) when ICE Brent front-month was trading around $73.70 a barrel, days after Strait of Hormuz traffic normalized under a 60-day US sanctions waiver on Iran. The physical logic has not visibly reversed since. If the supply buffer Goh described remained in place through late August, the current spot premium may owe more to positioning anxiety than to genuine production-run shortfalls.1
Between 6 and 8 million barrels a day of Middle Eastern crude moved through the Strait of Hormuz during the week of August 24 (2026-08-24), traders said, though recent attacks in the waterway had potentially reduced those volumes. That throughput remained within normal operational range. Analysts were working in late June (2026-06-26) toward converting the temporary Iran sanctions waiver into a permanent diplomatic arrangement; any such deal would erode the geopolitical tension that has helped sustain East-of-Suez differentials.6,1
A structural shift compounds the picture. From November 1, 2026, ADNOC will price all Abu Dhabi crude grades on a prompt-month basis using the Platts Dubai benchmark, one of the most significant changes to Middle Eastern crude pricing in years, the company said. Murban previously priced through its own futures mechanism. After November 1, ADNOC crudes price directly against Dubai, and the differential mechanics underpinning the current $30 Murban premium will shift materially. Traders buying the spread on September 8 are implicitly making a bet on its persistence through and beyond that transition.4,3
ADNOC has also broadened its commercial reach in ways that increase supply optionality for Asian buyers. Where it once sold exclusively to end-users on an FOB basis, ADNOC recently completed deliveries to trading houses including Mercuria, Vitol and Cathay Petroleum at ship-to-ship transfer points off Fujairah, Sohar and ports along the Indian coast, traders said. None of those buyers operates refineries. Their inclusion tends, over time, to sharpen price discovery and dampen the kind of differential spikes the current market is exhibiting.5
ICE Brent front-month carries a bearish supply-side signal on current analysis, as does WTI crude front-month. If Atlantic Basin supply continues rebuilding and Asian tanks remain close to capacity after ADNOC's six-month tender program, the bid for spot Murban could soften faster than the $30 differential suggests the market expects.5,2
The test will come when ADNOC issues its first cargoes priced under the new November Platts Dubai methodology. If those cargoes clear significantly below where prompt Murban has traded through the recent spot-buying spree, it will indicate that the current premium reflects pricing-mechanism distortion as much as genuine scarcity of light-sweet barrels in East Asia.4
