The 21:01 snapshot shows Brent at $102.266, barely changed at +$0.02 on the day, while WTI dropped $1.58 to $89.67. One benchmark flat, the other sliding — the spread jumped from the $11 range last week to $12.60, among the widest prints in two months.

The real signal sits in freight. WTI proxies US Gulf Coast light crude; add a VLCC run to China on the TD3C route (recently $2.1–2.4 per barrel) and the landed cost undercuts Brent-linked ESPO, Dubai and Oman by a clear margin. That window was shut while WTI traded strong; tonight it reopened.

For SNSUC's seven transshipment grades the buy ranking shifts: ESPO keeps the top slot on short haul (Kozmino to Qingdao, 5–6 days), but USGC spot now shows arb. Basrah Light and Bonny Light, Atlantic-basin cargoes, lose relative appeal, and Oman or Dubai premiums pinned high will get squeezed by cheaper WTI barrels near term.

Operationally, do not lock transshipment laycans at last week's spread. The WTI-weak and Brent-stable combo rarely holds beyond two weeks before mean reversion, but those two weeks are enough to capture a full landed-margin ride on one USGC cargo. Our duty-paid landed-cost model needs the USGC path weighted up today.
