Brent settled at $100.40 and WTI at $89.39, leaving the transatlantic spread at $11.01 per barrel. For SNSUC's seven-grade re-export book — ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light and Lula — that gap matters at the load port: a Gulf Coast cargo bound for Northeast Asia now carries roughly $0.4 more in benchmark spread cost than a few sessions ago.

The widening comes from the WTI side — inventories and pipeline flows — not from a Brent surge. That shifts the relative appeal of Far East discount grades. ESPO and Sokol look less attractive unless their discounts widen in step; otherwise buyers do better taking prompt Brent-priced barrels.

The 13-category listing formula tracks Brent: price = Brent x FX x 7.33 x grade factor. At today's marks the base is about 100.40 x 6.705 x 7.33 = RMB 4,934 per tonne before the grade multiplier. That base is the live anchor members see in the data terminal.
