Polysilicon Futures Plunge 5.8%, Breaching Key Cost Level

Futures Plunge 5.8% Below Production Cost Threshold

A critical signal emerged from the solar industry's upstream sector on March 19, as the main polysilicon futures contract on the Guangzhou Futures Exchange collapsed. The contract fell 5.77% to close at 38,550 yuan per ton, decisively breaking the 40,000 yuan/ton mark. This level is widely considered the cash cost line for some of the industry's leading producers, meaning they are now selling the material for less than the direct cost to produce it. The price action represents what one analyst called "extreme pressure" on high-cost capacity, signaling that the market is actively forcing out less efficient players.

Oversupply Crisis Intensifies with 520,000 Tons in Inventory

The price collapse is a direct result of a severe supply-demand imbalance plaguing the entire solar value chain. Polysilicon inventories have swelled to over 520,000 metric tons and continue to accumulate. This glut has intensified shipment pressure and challenges in clearing stockpiles. Downstream, wafer manufacturers, who are also operating below their own cash cost levels, have slashed procurement. They are now purchasing only on a just-in-time basis, creating a negative feedback loop that transmits cost pressure back upstream. The weakness extends further down, with cell prices falling to around 0.40 yuan/W and module buyers holding out for prices below 0.75 yuan/W.

Producers Face Below-Cost Sales as Consolidation Nears

The persistent price decline, which has seen some polysilicon grades fall over 13% year-to-date, is forcing producers into untenable positions. Even a major producer with a low cash cost of 33.95 yuan/kg and a full cost of 43.46 yuan/kg is operating in a difficult environment. The market price is now below the full cost for even the most efficient manufacturers. The China Photovoltaic Industry Association (CPIA) has voiced concerns over "unfair competition," noting some firms are selling at prices 17%-20% below the industry's average total cost. This environment makes a wave of production cuts, shutdowns, and industry consolidation almost certain as producers can no longer sustain operations by selling at a loss.
