China commodity futures night session closes broadly higher; TSR 20 rubber jumps 4.7%

The standout is the divergence within the rubber complex: TSR 20 and natural rubber posting outsized gains while synthetic rubber lags well behind, a split that points to feedstock-specific drivers rather than a uniform demand signal. Broader strength across coal and petrochemical intermediates suggests an input-cost or supply-side push rather than a consumption-led rally, given the simultaneous softness in PTA, paraxylene and soda ash. Whether the rubber-led move holds through the next session, or fades as the weaker downstream names suggest, is the open question.
