The article shows that as of December 18, 2025, the total inventory of float glass sample enterprises in China reached 58.558 million heavy boxes, an increase of 0.57% month on month and a significant increase of 25.73% year-on-year. The inventory days increased to 26.5 days (an increase of 0.2 days compared to the previous period). This indicates that there is an oversupply in the glass market, weak demand, and increased pressure on enterprise inventory accumulation, which poses downward pressure on spot prices. It is expected that enterprises may reduce prices to clear inventory. Based on the latest data of glass futures (such as the closing price of the main contract 2605 at 1,062 RMB/ton, up 25.00, and increased holdings), the increase in inventory is a fundamental bearish signal, which may trigger futures price adjustments in future trading and enhance market bearish sentiment.
