PVinsights: Order Cancellations Speeded Up China Polysilicon Price Drops

Alternative Energy - Thu, 02/08/2018 - 08:41
Polysilicon prices dropped this week driven by disappointed sentiment as downstream demand cuts loosen the polysilicon market. Polysilicon prices in China dropped notably as buyers could no longer withstand high polysilicon prices given limited affordability under severe downstream price pressure. High-purity polysilicon for the use of mono-crystalline only dropped limitedly since the major mono-crystalline wafer makers did not seem to curtail production as substantial as multi-crystalline wafer makers. Nevertheless, polysilicon buyers have strengthened their stance on slashing prices or threatened to cut procurement volumes with the plummet in the downstream components, leading polysilicon prices to retreat from highs. On overseas market, polysilicon continued to extend the drop over the week. With a clear downstream weakness, the overseas polysilicon buyers took conservative approach in terms of the procurement. In fact, with collapse on polysilicon prices in China, some traders have been dumping inventories in the spot market to selloff the stock. With increasing pressure from downstream slide, a slump of polysilicon prices in overseas were also witnessed this week.
