By the close of trading on July 10, polysilicon futures prices had soared 5.5%, decisively surpassing the 40,000 yuan/ton mark. The main contract price hit 41,345 yuan/ton, establishing a new high in nearly three months. Trading volume also spiked on the day, reaching a record 1.015 million contracts. In reaction to the overheated market conditions, the Guangzhou Futures Exchange (GFEX) announced on the evening of July 10 that it would implement a "margin hike and price limit expansion" policy effective from the settlement on July 14. This includes adjusting the daily price limit for polysilicon futures contracts to 9%, increasing the margin requirement for speculative trading to 11%, and setting the margin requirement for hedging transactions at 10%. Industry experts noted that this measure is intended to temper the overheated polysilicon market and effectively mitigate and manage market risks.
