1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - The industry is in a situation of strong expectations and weak reality. In the short - term, SH2603 is expected to show a volatile trend, with the range around 2100 - 2300. Due to relatively loose supply and weak downstream demand, liquid caustic soda factory inventories have accumulated. Although the supply of caustic soda is expected to be high in December, the negative factors cannot be realized in the short - term. The planned commissioning of alumina plants in the first half of 2026 gives some support to the long - term price. Non - aluminum downstream may maintain rigid procurement [3][4] 3. Summary by Related Catalogs 3.1 Futures Market - The main contract closing price of caustic soda is 2250 yuan/ton, up 31 yuan; the main contract position is 159,783 lots, down 5,156 lots; the net position of the top 20 futures is - 19,516 lots, down 4,283 lots; the main contract trading volume is 492,973 lots, up 149,306 lots. The closing price of the January contract is 2150 yuan/ton, up 12 yuan; the closing price of the May contract is 2358 yuan/ton, up 34 yuan [3] 3.2 Spot Market - The price of 32% ion - membrane caustic soda in Shandong is 720 yuan/ton, unchanged; in Jiangsu, it is 790 yuan/ton, down 30 yuan. The converted 100% price of 32% caustic soda in Shandong is 2250 yuan/ton, unchanged; the basis is 0 yuan/ton, down 31 yuan [3] 3.3 Upstream Situation - The mainstream price of raw salt in Shandong is 247.5 yuan/ton, unchanged; in the Northwest, it is 220 yuan/ton, unchanged. The price of steam coal is 643 yuan/ton, down 1 yuan [3] 3.4 Industry Situation - The mainstream price of liquid chlorine in Shandong is 75.5 yuan/ton, unchanged; in Jiangsu, it is 200 yuan/ton, up 25 yuan [3] 3.5 Downstream Situation - The spot price of viscose staple fiber is 12,900 yuan/ton, unchanged; the spot price of alumina is 2,665 yuan/ton, down 10 yuan [3] 3.6 Industry News - From December 12th to 18th, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 84.7%, a week - on - week decrease of 1.5%. From December 13th to 19th, the alumina operating rate decreased by 1.11% week - on - week to 85%. From December 12th to 18th, the viscose staple fiber operating rate remained stable at 89.62%, and the printing and dyeing operating rate decreased by 0.69% week - on - week to 62.06%. As of December 18th, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in the country was 464,700 tons (wet tons), a week - on - week increase of 1.66% and a year - on - year increase of 52.34%. From December 11th to 18th, the average weekly profit of Shandong chlor - alkali enterprises was 216 yuan/ton, an increase from the previous week [3] 3.7 Outlook - A 300,000 - ton unit in East China will restart this week, and a 160,000 - ton unit in Southwest China will be under maintenance. The capacity utilization rate of caustic soda is expected to increase slightly. There are few maintenance plans for chlor - alkali plants in winter, and the supply of caustic soda is expected to be high in December. The winter storage of aluminum plants downstream of alumina has ended and the raw material inventory is high, and the imbalance between supply and demand in the industry is expected to intensify. However, since enterprises have no large - scale inspection plans, the negative factors for caustic soda cannot be realized in the short - term. There are many alumina plants planned to be commissioned in the first half of 2026, which gives some support to the long - term price. Non - aluminum downstream may maintain rigid procurement with little change [3][4]

Report Summary 1. Report Industry Investment Rating - The report does not explicitly provide an overall investment rating for the PVC industry, but the trend strength of PVC is 0, indicating a neutral view [4] 2. Core View of the Report - The short - term rebound space of PVC is limited due to the high - yield and high - inventory structure in the PVC market that is difficult to change in the short term, high PVC warehouse receipts and large future long - position receiving pressure, and the large - scale inventory accumulation during the Spring Festival and the contango structure restricting the market's trading of low - valuation factors. However, the supply - side production cut in the maintenance peak season next year may exceed expectations, which is beneficial for the profit repair of the chlor - alkali industry. It is recommended to enter the market on the right side after seeing substantial large - scale maintenance plans on the supply side [3] 3. Summary by Relevant Catalogs 3.1 Fundamental Tracking - **PVC Fundamental Data**: The 01 contract futures price is 4450, the East China spot price is 4420, the basis is - 30, and the 1 - 5 month spread is - 288 [2] - **Spot News**: Domestic PVC spot transactions are mainly at a fixed price. The intraday price rose significantly driven by the policy atmosphere, but the market's rigid demand is cautious, and the purchasing enthusiasm is poor. The short - term supply - demand fundamentals are weak, and the trading confidence is insufficient. The ex - warehouse cash - on - delivery quotation of calcium carbide - based type 5 PVC in East China is 4400 - 4550 yuan/ton, and the ethylene - based PVC price is stuck at 4450 - 4600 yuan/ton [2] 3.2 Market Condition Analysis - Although the low valuation of PVC, factors such as anti - involution trading in the market, policy emphasis on stabilizing the real estate market, and large - scale stop - profit of short positions in the near - month contracts can drive a phased rebound of PVC. But this rebound space is limited because the high - yield and high - inventory structure of the PVC market is difficult to change in the short term. The winter is the off - season for chlor - alkali enterprise maintenance, and the scale of partial device maintenance and production reduction is limited. The futures contracts before the 03 contract still face a pattern of high start - up and weak demand. The expectation of large - scale production reduction may be after the 03 contract. The large - scale inventory accumulation during the Spring Festival and the contango structure will also limit the market's trading space for low - valuation factors. In addition, PVC warehouse receipts are still at a high level, and the future long - position receiving pressure is still large [3] - The comprehensive profit of chlor - alkali is at a historically low level. The supply - side production cut in the maintenance peak season next year may exceed expectations, which is beneficial for the profit repair of the chlor - alkali industry. It is recommended to enter the market on the right side after seeing substantial large - scale maintenance plans on the supply side [3] 3.3 Trend Strength - The trend strength of PVC is 0, with a range of [- 2, 2] for integer values. - 2 means the most bearish, and 2 means the most bullish. A value of 0 indicates a neutral view [4]

1. Report Industry Investment Rating No information provided in the content. 2. Core Views of the Report 2.1烧碱 - The later stage of caustic soda still faces pressure. The supply side has high production and inventory, and the winter is the off - season for chlor - alkali enterprise maintenance, resulting in large supply pressure. The demand side is affected by the low profit of alumina, seasonal decline in non - aluminum downstream demand, and weak export, making it difficult to support the overall demand. The valuation of caustic soda is suppressed by the alumina production reduction expectation, and it is difficult to rebound significantly without production reduction by manufacturers [5][6]. 2.2 PVC - The trend of PVC is weak. The high - production structure of PVC is difficult to change in the short term. The export market competition pressure increases in 2025, and the domestic demand related to real estate is weak. Although there may be phased rebounds, the space is limited. The high - production and high - inventory structure is difficult to change in the short term, but the supply - side production reduction in the maintenance peak season in the next year can be expected [9][10]. 3. Summary According to the Directory 3.1 Caustic Soda Price and Spread - The main logic of short - sellers includes high supply, high inventory, continuous expectation of alumina production reduction, new capacity in the next year, slowdown in export growth, and changes in delivery areas and delivery premiums. The main logic of long - sellers includes anti - deflation and anti - involution trends, large losses in integrated profits of caustic soda and PVC, and expansion of the export market due to overseas plant shutdowns [13]. - The basis of caustic soda 01 fluctuates, and the 1 - 5 month spread weakens [16]. - The export market of caustic soda still has support but also faces structural adjustment. In October 2025, China's liquid caustic soda export volume was 330,000 tons, with a year - on - year increase of 10.39% and a month - on - month decrease of 8.90%. The cumulative export volume from January to October was 2.944 million tons, a year - on - year increase of 41.93%. The cumulative export of caustic soda from January to October was 3.49 million tons, a year - on - year increase of 41.7%. It is expected that the annual export in 2025 will increase by at least 30% year - on - year and exceed 4 million tons [20][23]. - The regional arbitrage space between Shandong and Guangdong is acceptable, and the spread between flake caustic soda and liquid caustic soda declines, which is negative for caustic soda. The spread between 50% caustic soda and 32% caustic soda also declines, which is negative for caustic soda [31][34][36]. 3.2 Caustic Soda Supply - The market structure shows a decline in production and an increase in inventory. The average capacity utilization rate of caustic soda sample enterprises with a capacity of 200,000 tons and above in China is 84.7%, a week - on - week decrease of 1.5%. The inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in the country is 464,700 tons (wet tons), a week - on - week increase of 1.66% and a year - on - year increase of 52.34% [43][44][45]. - Attention should be paid to the significant reduction in maintenance after December. There are many enterprises in different regions with maintenance plans [49]. - Caustic soda will continue to be put into production in 2025 and 2026, with a capacity growth rate of over 3%. In 2025, the planned production capacity is 1.9 million tons, and in 2026, the planned and under - construction production capacity that can be put into production is 2.56 million tons [51]. - In December, the large - scale industrial electricity price in Shandong Province is reduced, and the cost of caustic soda is difficult to support. The price of liquid chlorine does not provide significant subsidies, and the cost support for caustic soda is limited [52][56]. 3.3 Caustic Soda Demand - In 2025, the alumina capacity expands greatly, with an expected new capacity of 9.5 million tons. As of November 2025, 8.3 million tons of new alumina production capacity has been put into operation. It is expected that there will still be 1.7 million tons of capacity to be put into operation in 2025, but the specific progress needs to be followed up. In 2026, the new alumina production capacity is expected to reach 13.9 million tons, with 76% in the southern market and 24% in the northern market [74][75][76]. - The alumina industry has a negative impact on caustic soda. The low profit of alumina leads to cautious procurement of caustic soda by alumina plants, a decrease in inventory levels, and difficulty in transferring caustic soda inventory downstream, resulting in a decline in caustic soda prices [90]. - The demand in the pulp industry is in the off - season, and the terminal profit is continuously compressed. The new capacity of pulp continues to be put into production, with 3.901 million tons in 2025 and 3.496 million tons in 2026 [91][97]. - The开工 rate of viscose staple fiber and printing and dyeing industries declines, the water treatment industry has stable operation, and the output of the ternary precursor industry declines [103][105][107]. 3.4 PVC Price and Spread - The main contract of PVC changes, the basis fluctuates and strengthens, and the 1 - 5 month spread fluctuates and weakens [112]. 3.5 PVC Supply and Demand - The PVC production enterprises' capacity utilization rate is 77.38%, a week - on - week decrease of 2.05% and a year - on - year decrease of 2.23%. The ethylene - based method is 76.54%, a week - on - week decrease of 2.36% and a year - on - year increase of 0.22%. The calcium carbide - based method is 77.74%, a week - on - week decrease of 1.92% and a year - on - year decrease of 3.04% [118][119]. - In December 2025, the maintenance of PVC decreases. There are long - term parking, maintenance, and temporary parking, as well as later - planned maintenance situations in different regions [121]. - As of 2025, 2.2 million tons of new PVC production capacity has been put into operation, and there is no new production capacity in 2026 [122]. - The chlor - alkali plants in Shandong are in a loss situation, reaching the cash - flow cost. The integrated profit of the northwest chlor - alkali plants is at a low level, and the impact of profit on supply is weakened in winter [124][127]. - PVC production enterprises have a slight inventory build - up, and the social inventory is at a high level. The real - estate terminal demand has not significantly recovered, and the overall downstream PVC开工 rate decreases month - on - month [128][133][139]. - In October 2025, the PVC export volume is 312,100 tons, and the cumulative export volume from January to October is 3.2338 million tons. The single - month export volume decreases by 9.91% month - on - month, increases by 34.28% year - on - year compared with the same month of last year, and the cumulative export volume increases by 48.88% year - on - year. India is still the most important destination for China's PVC exports [146]. - The PVC warehouse receipts decline but are still at a high level [148].

Core Views - The overall chemical market shows a mixed trend, with some products facing downward pressure and some having potential for short - term strength or long - term improvement [2][3][5][6][7][8] 3. Summary of Each Section Olefins - Polyolefins - Propylene futures dropped significantly. Production enterprises faced inventory pressure and increased the incentive to sell at a discount. The demand was negatively affected by the increase in the number of shutdown or planned shutdown of polypropylene plants [2] - Plastic and polypropylene futures may enter an accelerated downward phase. The supply pressure of polyethylene increased due to high - load operation and slow inventory digestion, and the demand was weak. The cost support of polypropylene weakened, and the demand was relatively weak [2] Pure Benzene - Styrene - The price of pure benzene rebounded slightly from a low level. The import pressure decreased slightly, and the supply - demand pressure may ease. It is recommended to consider long - term positive spreads on dips [3] - Styrene futures showed a weak consolidation.
