Both crude benchmarks climbed tonight. Brent settled at $113.15 a barrel, up $2.12 on the day, while WTI closed at $104.011, up $1.97. Both rose, yet WTI lagged Brent slightly, and the spread reopened from $8.71 earlier this month to $9.14.

The widening spread matters at the arrival end. U.S. Gulf Coast light crude tied to WTI needs more than 30 days to reach Northeast Asia by sea, whereas short-haul light-sweet grades such as ESPO, Dubai and Oman can discharge within 14 days. Once the spread widens, the arrival economics of U.S. Gulf cargoes are squeezed again by ESPO/Dubai, and refiners must reorder their feedstock intake.

On the other side, the yuan strengthened to 6.6531 tonight, about 0.25% firmer than last week's 6.67 line. At Brent's $113.15, the yuan-denominated landed and duty-paid cost works out to roughly 752.9 yuan per barrel, well below the ~763 yuan seen two weeks ago near 6.75. For dollar-priced crude, a stronger home currency effectively opens about 10 yuan per barrel of import-window room.

For SNSUC's seven transshipment grades the math splits. ESPO, Dubai and Oman are short-haul, so they capture the currency dividend directly at arrival. Urals, Basrah Light, Bonny Light and Lula ride long-haul routes where freight and war-risk premiums weigh heavier and eat part of that dividend. Within a single session the arrival ranking of these grades no longer moves in lockstep.
