The interesting part of tonight's tape is not that crude fell, but that it fell unevenly. Brent settled at $98.73, down 1.20%, and WTI at $95.41, down 1.87%. Both legs softened, yet the downstream complex did not follow. Bitumen closed at CNY 5,432/t, up 1.53% on the day; fuel oil at CNY 4,297/t, up 0.89%; even butadiene rubber added 1.87%. Refinery profit is anchored to the crack spread right now, not to the absolute oil price. For a transshipment desk, to-coast margin has to be rebuilt from delivered cost = FOB + freight + discount, not read off a single Brent quote. A wider WTI discount makes US Gulf cargoes better value into the US West Coast, while short-haul grades like ESPO hold their window on freight alone. What we track is the delivered, duty-paid price per cargo, not the headline "oil is down." In practice this mix is a buyer's gift: crude is cheaper while the downstream has not followed, so the timing of pricing and the hedge on FX can be staggered. But do not read "crude is weak" as "everything is weak" — bitumen and bunker strength will eat part of that delivered margin.
