PVinsights: Two Earthquakes Hit Northwest China, No Impact on Polysilicon Production

Alternative Energy - Fri, 08/11/2017 - 09:06
Polysilicon prices in RMB took a breather that the surge were slowing down after a lackluster China trading and as buyers awaited for more clues on downstream demand and maintenance impact, while the price quotes in USD showed a bigger increase supported by strengthening RMB. Two earthquakes hit Sichuan and Xinjiang overnight, rumors circled in the market that the earthquake would further reduce the polysilicon production, trying to boosting the prices to another rally. However, as both of the epicenters were at least 400 km away from the closest polysilicon factories and the production has been confirmed by suppliers without any impact, the earthquake would not raise another rally in the market. In overseas market, the polysilicon prices extended its gain but capped by resilient buyers as there was no supply shortage and the utilization rates remained low.
