Watching Brent alone is not enough. Fuel oil at 4,440 and bitumen at 5,161 are both crude cracks, yet their pricing logic diverges sharply. Fuel oil tracks refinery runs and bunker demand; bitumen tracks infrastructure activity and inventories. Once turnarounds begin, run rates fall, supply tightens, and prices need not follow crude down.

Rubber tells a richer story. Natural rubber at 19,850 against butadiene rubber at 15,955 leaves a spread near 3,900. NR follows weather and tapping rhythm in producing regions; BR follows butadiene and naphtha. When the synthetic route gets expensive while NR faces supply noise, tyre makers shift between the two feedstocks, buying whichever is cheaper.

For an operator in chemical trading, this divergence is both a margin source and a risk. Hedging crude cost does not hedge downstream margin — the crack spread and each product's inventory cycle still sit in between. Today's board is a reminder: do not infer downstream from a crude directional bet; price each product on its own terms.
