Core Viewpoint - Since 2025, PVC futures prices have hit a nearly ten-year low due to increased supply and decreased demand, particularly influenced by a sluggish real estate sector [1][2]. Supply - 2025 is expected to be a peak year for PVC capacity expansion, with an additional 2.2 million tons projected, leading to a total capacity of 29.93 million tons by year-end, a year-on-year increase of 7.35% [1]. - As of November 14, domestic PVC social inventory was 1.0282 million tons, a slight decrease of 1.27% month-on-month but a significant increase of 23.75% year-on-year, indicating high inventory pressure [1]. Demand - The current demand for PVC is characterized by "weak domestic and strong external" factors, with 80% of downstream demand related to real estate and infrastructure, both of which have seen declines in investment and new projects [1]. - The low operating rates in consumption areas such as pipes and profiles, along with a lack of positive factors in the infrastructure sector, contribute to overall weak demand [1]. Export - India's PVC demand has been growing, with a demand gap of 3 million tons per year, heavily reliant on imports. China's PVC exports to India surged from 7.3% in 2020 to 50.9% in 2024 [2]. - In the first nine months of 2025, China exported 3.3941 million tons of PVC, a year-on-year increase of 47.78%, with 1.215 million tons going to India, accounting for 41.6% of total exports [2]. Cost - Recent declines in oil and coal prices have weakened cost support for PVC, with prices falling below cost lines, leading to industry-wide losses [2]. - The integrated chlor-alkali enterprises are maintaining PVC production through high profits from caustic soda, but the price of caustic soda has dropped by 30% from its peak, making this strategy unsustainable [2]. Short-term Outlook - In the short term, PVC supply continues to grow while demand remains weak, leading to significant inventory pressure and insufficient upward price momentum [3]. - PVC is currently in a low valuation area, with negative factors largely priced in, suggesting limited downside potential. The market is expected to remain in a "bottoming out" and "capping" oscillation pattern, with the 2601 contract projected to trade between 4,400 and 4,800 yuan per ton [3].

Supply and Demand Dynamics - Since 2025, PVC futures prices have reached a nearly ten-year low due to increased supply and decreased demand, alongside a weak real estate sector [1] - In 2025, PVC production capacity is expected to peak with an additional 2.2 million tons, bringing total capacity to 29.93 million tons, a year-on-year increase of 7.35% [1] - As of November 14, domestic PVC social inventory was 1.0282 million tons, a slight decrease of 1.27% month-on-month but a significant increase of 23.75% year-on-year, indicating high inventory pressure [1] - The current demand for PVC is characterized by "weak domestic and strong external" factors, with 80% of downstream demand related to real estate and infrastructure, which have seen declines in investment and new projects [1] Export Trends - India's PVC demand has been growing, with a demand gap of 3 million tons per year, heavily reliant on imports; China's PVC exports to India surged from 7.3% in 2020 to 50.9% in 2024 [2] - From January to September 2025, China's PVC exports totaled 3.3941 million tons, a year-on-year increase of 47.78%, with 1.215 million tons exported to India, accounting for 41.6% of total exports [2] - It is expected that in Q4 2025, PVC exports to India will increase by 200,000 to 300,000 tons, which will help alleviate inventory pressure and improve the domestic supply-demand imbalance [2] Cost Pressures - Recent declines in oil and coal prices have weakened cost support for PVC; as of November 17, PVC prices fell below the cost line, leading to industry-wide losses [2] - The losses for the calcium carbide method are 700 yuan per ton, while the ethylene method faces losses of 560 yuan per ton [2] - Chlor-alkali integrated enterprises are maintaining PVC production through high profits from caustic soda, but the price of caustic soda has dropped by 30% from its peak this year, making it difficult to sustain this model [2] Market Outlook - In the short term, PVC supply continues to grow while demand remains weak, leading to significant inventory pressure and insufficient price increase momentum [3] - Currently, PVC is in an undervalued region, with negative factors largely priced in, suggesting limited downside potential for prices [3] - The PVC futures market is expected to remain in a "bottoming out" and "capping" oscillation pattern, with the 2601 contract projected to trade between 4,400 and 4,800 yuan per ton [3]

It will maintain a weak and volatile trend in the short term [2]. - PP's weak supply - demand situation is hard to reverse, and the cost - side support also weakens. It will continue the weak and volatile pattern in the short term [3]. - For investment strategies, it is recommended to wait and see for unilateral trading; for inter - period trading, conduct sell - near - buy - far arbitrage for L01 - 05 and PP01 - 05; there is no recommendation for inter - variety trading [4]. 3.

Future planned maintenance is limited, the operating rate continues to rise, and new production capacities such as Guangxi Petrochemical are gradually released, so supply pressure persists [2]. - **Demand**: PE downstream overall operating rate declined month - on - month. Agricultural film demand is expected to shrink, and packaging film operating rate decreased month - on - month. Overall downstream demand is still limited [2]. - **Inventory**: Due to the unimproved supply - demand contradiction, inventory pressure persists, and there is a lack of upward drivers in the short term [2]. 3.2.2 PP - **Cost**: Coal prices dropped significantly, and although international oil prices fluctuated widely and the price of propane rebounded slightly, cost support is still limited [3]. - **Supply**: Newly added device shutdowns in Sinochem Quanzhou Line 1 and Guangdong Petrochemical Line 2, and the full - scale shutdown of Juzhengyuan's 120 - million - ton PDH device for maintenance. Although short - term temporary maintenance eases supply pressure, it has limited impact on the oversupply pattern. Upstream is actively reducing prices to sell, but demand is weak, and inventory clearance pressure is high [3]. - **Demand**: Downstream overall operating rate is gradually weakening, mainly replenishing inventory on a just - in - time basis when prices are low. Demand follow - up is still weak [3]. - **Market Outlook**: The loose supply - demand fundamentals may limit its rebound space, and it will continue the weak and volatile pattern in the short term [3]. 3.3 Strategy - **Unilateral**: Wait and see. It is in a short - term volatile pattern, and prices are still under pressure in the long term [4]. - **Inter - period**: Conduct sell - near - buy - far arbitrage for L01 - 05 and PP01 - 05 when prices are high [4]. - **Inter - variety**: No recommendation [4]
