Both benchmarks slipped and the spread pulled back to $8.97; a firmer yuan drove Brent's RMB landed cost to about ¥731/bbl, reopening the short-haul light-sweet feedstock window.

The Brent–WTI premium compressed from $13.54 on Oct 23 to $8.61. CIF costs on the seven transshipment grades — ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light, Lula — must be recalculated on the new spread.

Brent closed at $109.95 and WTI at $98.79, leaving an $11.16 spread. Delivered costs for the seven transshipped grades (ESPO, Dubai, Oman, Urals, Basrah Light, Bonny Light, Lula) are rebuilt against the discount structure.

Brent at $107.774 and WTI at $97.412 push the spread from $8.08 to $10.36. Two market logics diverge, forcing a reset of delivered floors across SNSUC's seven transshipment lines.

Brent at $105.70 and WTI at $95.55 leave a $10.14 spread, some $2.50 below the $12.64 of October 13, reopening the arrival-cost gap across the transfer book.
