5、Price Forecast

The domestic PVC fundamentals have not improved recently, with fewer maintenance activities at upstream production enterprises combined with new additions, leading to a significant increase in market supply month-on-month. Meanwhile, domestic demand remains stable, and foreign trade exports are mainly focused on fulfilling existing orders. The supply-demand contradiction has intensified, with industry inventory expected to accumulate significantly, putting pressure on the market. On the macroeconomic front, the market prices have seen a slight increase driven by factors such as coke in the black sector, but there has been no impact on costs and other factors. In the short term, the market fundamentals remain under pressure from supply and demand, with spot prices experiencing weak fluctuations. Macro sentiment during trading hours can easily interfere with market trends. It is expected that the East China region's calcium carbide method for type 5 cash-on-delivery warehouse pick-up will be priced at 4,800-4,950 yuan/ton.
