Polysilicon prices in China jumped the most in almost two years after a broad pledge by the country’s top leadership to curb competition among businesses boosted optimism in the outlook for the industry.

While the vow by Beijing last week didn’t specify sectors, there’s some speculation that solar will be included in the government campaign. Polysilicon prices rose between 6.3% and 6.9% in the week through Wednesday, according to data from an industry association, the most since August 2023.
