The Middle East official selling prices are numbers every Asian buyer tracks each month. ADNOC's Murban, the medium-sour grades from Saudi and Kuwait, and the Dubai and Oman averages together set the upstream cost of resale grades such as ESPO, Dubai and Oman. Brent is above $113, yet the discount of Middle East sour crudes to Brent is narrowing: when physical barrels are tight, the seller need not deepen the discount to fill loading windows.

The spread between Dubai and Oman premiums deserves a separate look. The Dubai monthly average is driven by published window trades, while Oman leans more on term contracts. When that gap widens, cargoes lifting directly from Oman look cheaper than those routed through Dubai, and the delivered ranking of the seven grades must be reordered. ESPO, as a short-haul light sweet, earns its slot on freight advantage, but once Middle East discounts shrink, its delivered economics get caught up.

On the currency side, the dollar weakened against the RMB, yen and won, and EUR/CNY also fell to 7.4284. Asian buyers pay for dollar crude in local currency and see lighter bills; European refiners benefit too. But Middle East sour grades are priced in dollars, so the FX dividend is shared by all buyers. What really separates them is the OSP discount and freight, not the exchange rate.

For resellers, a time window sits between the OSP announcement and the loading date: once official prices lock, if Brent keeps climbing, downstream buyers on term contracts gain; if it falls, the floating portion bears the markdown. The delivered ranking of the seven grades is rewritten each month with OSP and freight, and the flexibility of title transfer at STS anchorages such as Sohar and Fujairah is the slack left for that reordering.
