Both benchmarks closed lower in the Asian session: Brent at $101.41/bbl, down $0.82, and WTI at $89.97/bbl, down $1.25. The synchronized drop was uneven — WTI fell harder, stretching the Brent–WTI spread to $11.44. That spread has climbed from the $4 handle two weeks ago to above $11, a clear signal that the premium on light sweet grades (WTI, ESPO and similar low-sulfur light barrels) over medium sour crude has not narrowed.

For a reseller the spread structure matters more than the absolute level. A deeper WTI slide reshapes the landed economics of US Gulf Coast arbs relative to short-haul Mideast cargoes. On a 1-million-barrel cargo, the delivered cost from Houston via Panama to Shandong versus a direct short-haul lift from the Persian Gulf or Oman loader is closing, but the US Gulf freight leg — Panama plus the VLCC second stage — still eats most of the advantage. Short-haul ESPO and Dubai keep the lead in the delivered ranking.

The exchange rate took the other side of the cost down. USD/CNY held at 6.705, virtually flat on the day, while EUR/CNY dropped to 7.4829 and EUR/USD to 1.1162. In RMB terms the landed duty-paid cost (Brent × FX × 7.33 × grade factor) came in cheaper than last week when the euro leg was strong. The 7.33 barrel-tonne ratio and the grade coefficient in the quoting formula are unchanged; what moved was the FX term. Hedging near 6.705 instead of 6.75 saves roughly RMB 30–40 per tonne.

The operational read is straightforward: a wide spread plus a steady yuan reopens the buy window for short-haul light sweet grades (ESPO, Dubai, Oman), and refiners can lean their pricing toward 6.705. Until the spread retracts, US Gulf WTI cargoes stay lower in the delivered ranking unless freight corrects materially. At $11.44 the spread looks structural — a light-sweet premium, not a one-day blip.
