Industrial silicon futures close up 1.18%

China's industrial silicon futures closed at Yuan 8,585/t on November 11, up Yuan 100/t or 1.18%, while the most-active polysilicon contract rose Yuan 330/t to Yuan 34,535/t. East China spot prices held at Yuan 9,300-9,400/t for 553# material and Yuan 9,500-9,600/t for 421#, with the source not stating delivery terms or VAT treatment. Support came from supply-side expectations and a rebound in coking coal prices. Smelters held firm offers, but buyers purchased only for immediate needs. Overseas buyers should expect firm near-term quotations while southwest dry-season supply losses persist, although weak polysilicon demand limits sustained upside.
