Guangzhou Institute: Make solid preparations for the listing of polysilicon futures and options to ensure the smooth launch and steady operation of polysilicon futures and options. With the rapid development of polysilicon industry, the relationship between supply and demand changes rapidly and the price fluctuates greatly due to various factors such as industrial policy, production cycle and technological progress. Due to the lack of objective and continuous price signals, the polysilicon industry has concentrated capacity investment and construction, which is prone to problems such as staged supply and demand mismatch, which is not conducive to the healthy and stable development of the industry. In this context, photovoltaic industry chain enterprises have increasingly strong demands for listed polysilicon futures, pricing with futures tools and managing risks. At the same time, the listed polysilicon futures will help to export the international pricing benchmark, form the "China" price of polysilicon international trade reflecting China's industrial volume, and gradually enhance China's influence in polysilicon international trade pricing. The insiders believe that at present, the industrial silicon varieties in Guangzhou have been running smoothly for nearly two years, and the listing of polysilicon varieties will further improve the variety layout of the crystalline silicon industrial chain for futures services, and provide more accurate futures tools for polysilicon and its downstream photovoltaic industrial chain, which is conducive to further consolidating the global competitive advantage of China's photovoltaic and other industries. The relevant person in charge of the Guangzhou Stock Exchange said that in the next step, under the guidance of the China Securities Regulatory Commission, the Guangzhou Stock Exchange will make solid preparations for the listing of polysilicon futures and options to ensure the smooth launch and steady operation of polysilicon futures and options.
