The Brent–WTI gap closed today at $11.458, another $0.30 wider than the $11.154 seen on October 4 and close to the two-week high. For crude transshipment desks, this spread is not a chart ornament — it decides which voyages can open a letter of credit and which have to wait for a window.

Among the seven grades SNSUC trades, ESPO and Sokol flow to the Far East and track WTI; Dubai and Oman are Middle East official-selling-price benchmarks priced off Brent; Urals swings between Mediterranean and Indian refiners; Basrah Light, Bonny Light and Lula represent the heavy-sour end. A softer WTI makes the WTI-anchored ESPO delivered cost more attractive, while the Brent-priced Dubai/Oman get comparatively expensive, opening a $1–2/bbl switch margin between routes.

In execution, SNSUC locks its quote formula to Brent × FX × 7.33 × grade factor, so a wider spread amplifies the weight of the grade factor. In the October spot allocation talks, buyers watch this window: when WTI trades more than $10 below Brent, pulling ESPO from a Far East bonded tank instead of lifting Dubai from the Gulf can, after freight and discount, absorb more than half of the $10/bbl margin that the ASI intermediary layers on.

One point often missed: a widening spread usually rides on tight U.S. inventories and a draining Cushing hub, which can squeeze the WTI front month — yet physical demand from Far East buyers does not shrink accordingly. So a wider spread is not the same as wider transshipment profit; it merely splits the pricing anchor into two legs. Desk practice must hedge both the FX and the ship date, or a $11 spread can lose a third of its value to currency swing inside a two-week voyage.
