Silicon Prices Kept Hitting New Highs amid Raw Material Shortage and Power Curtailment

SHANGHAI, Aug 16 (SMM) - The price trend of silicon was extreme in July. The prices of #553 oxygen-free silicon fell by 300 yuan/mt in early July, while the prices of silicon of other specifications stood stable.

After mid-July, Baoshan, Dehong, and Nujiang in Yunnan frequently implemented power curtailment, and the supply of cleaned coal was tight with lower grade. This, coupled with the sudden shutdown of a large silicon plant in Xinjiang, led to the short supply of silicon spots, and the prices kept rising to reach a record high.

The #421 silicon plants need high-grade cleaned coal as raw materials, and some plants had to change raw material purchase channels for lack of resources. Silicon plants frequently failed to deliver goods on time or in full quantity. The purchase volume by downstream organosilicone companies fell short of expectation. The raw material shortage cannot be alleviated in the short term, and the operating rates will not rise due to the power curtailment. #421 silicon will remain in tight supply in August, and the prices will keep going up. 

A previously suspended silicon plant in Xinjiang gradually resumed production since August 6. The tight supply of low-grade metallurgical silicon was eased, while traders and downstream users held mostly wait-and-see attitude. The holders gradually stabilised the quotations for the #553 oxygen-free silicon, and the prices are unlikely to further increase without new consumption from downstream aluminium alloy sector.

Such a price trend in the wet season was rare. The supply of high-grade silicon is tight, and downstream users are willing to accept the high prices, so silicon plants are highly intended to raise prices. The prices of high-grade silicon is expected to keep rising in August, the prices of low-grade oxygenated silicon will increase steadily, and the prices of oxygen-free silicon is likely to fall back in late August.

Silicon Metal Market Review for January and Outlook for February
In January, the silicon metal market experienced a relatively loose supply-demand balance, with a theoretical inventory buildup of approximately 30,000 mt. In February, both supply and demand contracted simultaneously, and the market is expected to show a tight balance or minor destocking. The current high industry inventory still requires time to be digested, and the sustainability of destocking remains a key variable affecting price trends and market sentiment.

A plant in northern China is calling for bids for indium ingots and bismuth ingots
SMM, February 6 - According to SMM’s investigation of market information, a large smelter in northern China began public bidding for a certain quantity of indium ingots and bismuth ingots starting yesterday. Market sources indicate that the starting price for these indium ingots exceeds 4,000 yuan per kilogram, while the starting price for bismuth ingots is above 150,000 yuan per ton. The bidding results are expected to be announced before the Spring Festival. Market participants note that, given the clear trend of sluggish trading activity ahead of the Spring Festival, the timing of this bidding is not ideal. However, the relatively favorable starting prices have generated considerable market anticipation for the outcome of the bidding.
