Night session opens: Shanghai nickel falls over 2%, styrene and methanol down nearly 2%

The breadth of the decline — spanning base metals, energy and petrochemicals simultaneously — points to a macro-driven risk-off move rather than any single commodity's fundamentals, with nickel's outsized drop suggesting it carries the most speculative positioning. The divergence in rubber, where both No. 20 and synthetic grades rose, is the notable exception and hints at demand or supply dynamics specific to that complex. Whether rubber's gains hold while the rest of the board stays weak is the signal worth tracking.
