1. Report Industry Investment Rating - Not provided in the content 2. Core Views - In 2025, PVC prices trended downward in a volatile manner. In 2026, demand is expected to improve slowly, with real - estate data showing a slower decline year - on - year. Indian demand and exports are likely to increase. Supply expansion will slow down, and spring maintenance may reduce supply pressure. Overall, PVC prices are expected to bottom out in a volatile way, first falling and then rising. Pay attention to changes in the operating rate. When the operating rate decreases or macro - policies are released, consider going long. If macro - policies are ineffective, PVC futures prices are expected to fall back. Spot enterprises can seize opportunities when the basis is strong [3]. 3. Summary by Relevant Catalogs 3.1 PVC Futures and Spot Prices - **Futures prices**: In 2025, PVC futures prices were affected by factors such as supply, downstream demand, international policies and conflicts. They fell overall, with small rebounds in May and 6 - 7 months, and hit a record low in mid - December before rebounding [3][5]. - **Spot prices**: PVC spot prices followed the futures prices, with a high correlation coefficient of 0.981 between PVC futures and East China spot prices. In 2025, the basis and inter - month spreads were mostly negative, especially during the main contract change. The 01 contract basis rose to a neutral level in December, but the 05 contract basis dropped to a low level [12]. 3.2 PVC Upstream - **Calcium carbide**: In 2025, calcium carbide prices first decreased and then increased, with the overall price center shifting down. The profit of calcium carbide in Wuhai was mostly negative, but production increased by 13% from January to November. It is expected to be in a state of oversupply in 2026 [24]. - **Semi - coke**: Semi - coke prices also first decreased and then increased in 2025, mostly at the lowest level in recent years. The operating rate first decreased and then increased, and the profit was mostly in a loss state [24]. - **Caustic soda**: From January to November 2025, caustic soda production increased by 4.8% year - on - year to 42.326 million tons. Prices rose at the beginning of the year and then fell due to factors such as alumina production expectations and cost changes [25]. - **Profit**: In 2025, the external calcium carbide method and ethylene method were always in a loss state, but the caustic soda profit was good. The comprehensive profit of chlor - alkali was mostly profitable. However, since the fourth quarter, the comprehensive profit of chlor - alkali has been declining, and some enterprises have fallen into losses [28]. 3.3 PVC Production, Capacity and Maintenance - **Production**: In November 2025, PVC production was 2.0793 million tons, a month - on - month decrease of 2.29% and a year - on - year increase of 5.62%. From January to November, the cumulative production increased by 4.38% year - on - year to 22.3242 million tons [35]. - **Capacity**: In 2025, the actual PVC capacity increased by 2.08 million tons to 29.62 million tons, with a growth rate of 7.55%. In 2026, only the 300,000 - ton/year new capacity of Zhejiang Jiaxing Jiahua will be put into production, and the capacity expansion will slow down significantly [47]. - **Maintenance**: In 2025, there were few long - term shutdown and maintenance devices. Pay attention to whether the number of maintenance devices will increase significantly under the pressure of comprehensive chlor - alkali profit [49]. 3.4 PVC Import and Export - **Import**: In November 2025, China's PVC import volume was 15,700 tons, a year - on - year decrease of 1.70% and a month - on - month increase of 44.15%. From January to November, the cumulative import volume was 202,100 tons, a year - on - year increase of 1.46% [62]. - **Export**: In November 2025, the export volume was 275,300 tons, a year - on - year increase of 29.64% and a month - on - month decrease of 11.78%. From January to November, the cumulative export volume was 3.5091 million tons, a year - on - year increase of 47.17%. India is the largest export destination, and the abolition of BIS certification and anti - dumping tax is beneficial to exports [62][67]. 3.5 Real - Estate Data - In 2025, from January to November, real - estate development investment decreased by 15.9% year - on - year, the sales area decreased by 7.8%, the sales volume decreased by 11.1%, the new construction area decreased by 20.5%, the construction area decreased by 9%, and the completion area decreased by 18.0%. In 2026, it is expected that policies will continue to support the real - estate market, but it will take time to strongly support PVC [71][74][75]. 3.6 PVC Downstream - **Operating rate**: The overall downstream operating rate of PVC was weak in 2025, especially from April to September. As of the week of December 19, it decreased by 3.50 percentage points to 45.39%. PVC film had a relatively high operating rate of about 70%, while pipes and profiles had a lower operating rate of about 40% [81][89]. - **Exports of floor coverings**: From January to November 2025, the cumulative export of PVC floor coverings was 380,380 tons, a year - on - year decrease of 10.88%. Exports are expected to remain at a low level due to US tariffs, but the improvement of US sales needs attention [90]. 3.7 PVC Inventory - **Factory inventory**: As of the week of December 19, 2025, the factory inventory decreased by 4.59% month - on - month to 328,500 tons, an increase of 14.86% compared with the same period last year, and an increase of 22.35% compared with the beginning of the year [92]. - **Social inventory**: After seasonal inventory accumulation after the Spring Festival, the social inventory decreased from mid - March and then increased continuously from July. As of the week of December 19, it decreased by 0.25% month - on - month to 1.0566 million tons, an increase of 28.58% compared with the same period last year and an increase of 33.74% compared with the beginning of the year. High inventory will limit the rebound of PVC prices [97].
