Fuel oil and bitumen rose together while natural rubber led a slide and butadiene rubber flattened; the book now runs two quoting formulas.

Four key contracts diverged sharply today: fuel oil +2.0%, bitumen −1.13%, natural rubber +3.76%, butadiene rubber +2.6%. High-amplitude contracts suit basis trading and receipt-backed financing; low-amplitude, steady-trend contracts suit fixed long-term pricing. SNSUC's data backbone across thirteen categories makes that screening concrete.
