Styrene rises 2.1% in night trading; PVC up 0.9%, coke up 0.1%

The split within the night session is the story: styrene and PVC firming while LPG and iron ore weaken suggests moves are being driven by product-specific supply-demand factors rather than a single macro impulse across the complex. Styrene's larger gain stands out relative to the modest PVC move, hinting at tighter conditions in that chain specifically. Whether LPG's slide persists alongside firming petrochemical intermediates is the open question, since the two often move together.
