Core Viewpoint - PVC prices have been under significant pressure due to capacity expansion, hitting a record low in 2025, with prices dropping below 4500 yuan/ton, exacerbated by weak demand and the cancellation of export tax rebates [1][4][8] Group 1: Price Trends and Profitability - PVC prices have consistently declined in recent years, reaching new lows, with production costs not sufficiently supporting prices due to ongoing losses in the calcium carbide method, which exceeded 1500 yuan/ton [4] - The integrated chlor-alkali enterprises have been able to offset PVC losses with caustic soda profits, but as caustic soda prices fell in the second half of 2025, combined profits turned negative, leading to a reduction in PVC production [4] - As production cuts occur, PVC supply pressure eases, allowing for a slight price rebound and some recovery in PVC valuations [4][8] Group 2: Demand Dynamics - The real estate sector, which accounts for 80% of PVC demand, has been in a downturn, with significant declines in sales area (down 15.6%) and sales revenue (down 23.6%) reported in December 2025 [5] - Seasonal demand fluctuations are evident, with PVC demand typically slowing during winter and the Spring Festival, leading to near stagnation in demand as the holiday approaches [5] Group 3: Export Market Changes - Recent policy changes announced by the Ministry of Finance and the State Administration of Taxation will remove the VAT export rebate for PVC products starting April 1, 2026, increasing export costs by approximately 80 USD/ton [6][7] - Despite a significant increase in PVC exports in recent years, with 2024 exports exceeding 2.6 million tons and projected to reach 3.8 million tons in 2025, the cancellation of export rebates is expected to diminish price advantages and limit future export volumes [7][8] Group 4: Future Outlook - While PVC prices have temporarily rebounded, the long-term outlook remains constrained by weak demand and the impact of export rebate cancellations, which may exacerbate domestic supply-demand imbalances and limit price increases [8]

Report Summary 1. Investment Rating The provided content does not mention the industry investment rating. 2. Core Views - **Caustic Soda**: The mainstream regional liquid caustic soda market prices continued to decline this week. High开工 and poor sales led to inventory accumulation. With weak supply - demand fundamentals, short - term prices are under pressure, and the short - term driving force remains weak [3]. - **PVC**: Domestic PVC prices rose and then consolidated this week. Although the market sentiment is good and the trend is relatively strong, with the approaching Spring Festival, downstream production demand is weakening, and inventory is rapidly accumulating. Also, the support from raw material calcium carbide is weak. It is expected that the upward space of PVC prices is limited, and it may fluctuate between 4700 - 5000 yuan/ton in the short term [4]. 3. Summary by Directory Caustic Soda - **Price and Market**: The weekly average price of 32% caustic soda in Shandong was 633 yuan/ton, a month - on - month decrease of 6.36%. There were frequent low - price situations in the week, impacting the market. The main downstream unloading was still difficult, and order transactions were light [3]. - **Supply**: As of Thursday, the weekly weighted average operating load rate of major sample enterprises nationwide was 90.87%, an increase of 1.73 percentage points from last week. There were sporadic short - stops of chlor - alkali plants, but some previously reduced - load plants resumed production [28]. - **Inventory**: On January 21, the inventory of 32% liquid caustic soda of expanded sample enterprises in East China increased by 5.52% compared with January 14. In Shandong, the inventory decreased by 0.44% [28]. - **Device Dynamics**: There were some ongoing and planned maintenance situations of domestic chlor - alkali enterprises. For example, Wuhai Chemical in the Northwest has been shut down since July 22, 2023, and the start - up time is undetermined. Chongqing Tianyuan in the Southwest plans to have maintenance in March, but the specific time is undetermined [30]. - **Downstream Industry - Alumina**: From the end of 2024 to 2025, the planned new - to - be - put - into - production capacity of alumina is 12.3 million tons (including 2 million tons of replacement). It is estimated that the annual production of alumina in 2025 will be over 88 million tons, with a production growth rate of around 6%. The new alumina demand is equivalent to 400,000 - 550,000 tons of caustic soda per year, and the total demand increment for caustic soda is around 800,000 tons. Recently, alumina futures prices have risen and then fallen, and the fundamentals are still weak. It is expected that the price will continue to operate weakly in the range of 2650 - 2850 yuan/ton [34][38]. - **Export**: In December 2025, China's liquid caustic soda imports were 62.6 tons, a year - on - year increase of 225.8% and a month - on - month increase of 40.7%. Exports were 309,638.3 tons, a year - on - year increase of 2.4% and a month - on - month increase of 69.3% [59]. Polyvinyl Chloride (PVC) - **Price and Market**: Domestic PVC prices rose and then consolidated this week. As of now, the spot ex - warehouse price of calcium carbide - type five - grade in East China is 4520 - 4620 yuan/ton, and that of ethylene - type is 4700 - 4800 yuan/ton [4]. - **Supply**: The operating load rate of the domestic PVC industry slightly decreased, with some enterprises having unplanned production cuts, but overall supply remained at a high level [4]. - **Device Dynamics**: There were no new maintenance enterprises this week, and the maintenance loss this week was 44,280 tons, a month - on - month increase of 5700 tons. It is expected that the maintenance loss will slightly decrease next week [74]. - **Downstream Industry - Real Estate**: The real estate industry is still in the bottom - building cycle, with indicators such as housing sales price index, land transaction area, and commercial housing sales area showing weak performance [75]. - **Inventory**: The total PVC inventory is still at the highest level in recent years [82]. - **External Market**: Some external PVC prices have weakened [89].

Group 1 - The domestic PVC powder market price has slightly decreased, with futures experiencing fluctuations and a mix of point pricing and fixed pricing, leading to general transaction activity [1] - The overall operating rate for PVC powder this week is 78.85%, an increase of 1.37 percentage points from last week, with the calcium carbide method at 82.21% and the ethylene method at 71.12% [2] - As of November 27, the inventory of PVC production enterprises in China has a production capacity of 5.35 days, reflecting a 0.94% increase, indicating a slight rise in upstream supply amid weak seasonal demand [2] Group 2 - Recent news indicates that Westlake Chemical in the U.S. has eliminated certain PVC production capacities, which has led to a significant rebound in the market, with expectations for increased exports to alleviate domestic supply pressure [3] - The demand side remains weak, particularly in the traditional off-season from November to January, with reduced outdoor construction in northern regions and a negative impact on overall real estate demand [3] - Despite the cancellation of the PVC BIS certification policy in India, which could benefit domestic exports, the anticipated anti-dumping tax execution may limit significant improvements in external demand [3]

Report Industry Investment Rating No relevant content provided. Core Viewpoints of the Report Caustic Soda - The caustic soda industry still faces certain supply - demand pressures. Shandong chlor - alkali enterprises are operating at a high level, and there are still vehicle - queuing situations at major downstream enterprises. Enterprises have high inventories, and there are no short - term positive factors. The price is expected to be weak in the next week. In the East China region, supply will remain abundant, the traditional off - season for demand will continue, and exports are not significantly boosted. It is estimated that the price in East China will continue to decline. Overall, the demand side provides weak support, and there are still long - term supply - demand pressures. The price of caustic soda is expected to run weakly [2]. - Futures strategy advice: Adopt a bearish approach. - Options strategy advice: Stay on the sidelines. PVC - The supply pressure will not ease next week, and the operating rate still has room for improvement. The operating rate of pipe and profile products remains low, while the soft products will remain in high demand, and export orders may increase slightly. The cost - side support is expected to continue to strengthen, and the PVC market is expected to continue to operate in a range. From November to January of the following year is the traditional off - season for demand. As outdoor construction in the north gradually decreases in winter, the overall real - estate demand reduction still has a negative impact. In terms of exports, the inventory in the Indian region is currently at a high level, the purchasing enthusiasm is average, the international market competition is fierce, and the export boost is limited. The overall demand side provides weak support for PVC, the supply - demand situation remains in an oversupply pattern, the price is not optimistic, and although the absolute price is low, it is difficult to form a continuous upward drive. It is expected to continue the bottom - weakening pattern [3]. - Futures strategy advice: Treat rebounds with a bearish attitude. - Options strategy advice: Stay on the sidelines. Summary by Relevant Catalogs Caustic Soda Market Performance - The caustic soda market has shown various trends due to factors such as macro - environment changes, supply - demand relationships, and cost fluctuations. For example, the 8 - month contract repaired the basis, and the market accelerated its decline. The spot market was in a game, and there were concerns about the marginal weakening under the subsequent supply recovery, with the downstream demand being stable [6]. Supply - As of Thursday this week, the weekly weighted average operating load rate of sample enterprises in major regions across the country was 89.86%, a 0.17 - percentage - point increase from 89.69% last week. There were few chlor - alkali device overhauls this week, and the operating load rate increased slightly. In Shandong, it was 91.45%, a decrease of 0.21% [25]. - On December 3rd, the inventory of 32% liquid caustic soda of expanded sample enterprises in East China was 253,150 tons, a 3.16% decrease from 261,400 tons on November 26th. The inventory in Shandong decreased slightly due to some factories delivering goods to downstream, and the overall inventory in East China decreased. The inventory of 32% liquid caustic soda of expanded sample enterprises in Shandong was 120,400 tons, a 3.53% decrease from 124,800 tons on November 26th [25]. Device Dynamics - There are multiple caustic soda production enterprises with various overhaul situations, including long - term shutdowns, current overhauls, and future planned overhauls. For example, Wuhai Chemical in the Northwest has been shut down since July 22, 2023, and the start - up time is undetermined; Zhejiang Juhua in the East China has been operating at half - load since October 11, continuing until January 1, 2026 [26]. Downstream Demand - Alumina: From the end of 2024 to 2025, the planned alumina production capacity to be put into operation is 1.23 billion tons (including 200 million tons of replacement). It is estimated that the annual production capacity growth rate will be around 10%. The estimated annual alumina production in 2025 will be over 88 million tons, with a production growth rate of around 6%. The new alumina demand is estimated to require an additional 400,000 - 550,000 tons of caustic soda per year, and the total demand increase for caustic soda is around 800,000 tons, with a relatively concentrated demand increase of 150,000 tons from April to June [30]. - Currently, the domestic alumina futures and spot prices are both poor, market confidence has not been significantly restored, and it is expected that the price will maintain a weak adjustment trend, with the price operating in the range of 2,700 - 2,900 yuan/ton [34]. - Non - aluminum downstream industries: The textile operating rate has declined, while the viscose staple fiber operating rate has increased [49]. Export - In October, caustic soda exports weakened, and the estimated export profit declined [56]. PVC Market Performance - The PVC futures market has been affected by factors such as supply - demand relationships, macro - sentiment, and cost. For example, due to the lack of positive supply - demand drivers and a poor commodity atmosphere, the futures price has continued to decline [63]. Profit - The industry profit of PVC has continued to deteriorate, and the profits of various production methods such as the calcium carbide method and ethylene method in East China and the northwest region have shown different degrees of decline [69]. Supply - This week, the operating load rate of the domestic PVC powder industry increased slightly. Only one enterprise had a temporary shutdown this week, and the previously overhauled enterprises gradually resumed production, resulting in a decrease in overhaul losses. The overall operating load rate of PVC powder this week was 79.01%, a 0.16 - percentage - point increase from last week; among them, the operating load rate of calcium carbide - based PVC powder was 82.09%, a 0.12 - percentage - point decrease; and the operating load rate of ethylene - based PVC powder was 71.92%, a 0.8 - percentage - point increase [85]. Device Dynamics - There are long - term shutdowns, current overhauls, and future planned overhauls of PVC production enterprises. For example, Taiwen Yanhua in North China has been shut down since September 30, 2022, and the start - up time is undetermined; Ningbo Hanwha in East China plans to conduct an overhaul from December 15th to December 28th [87]. Downstream Demand - The two major downstream industries of PVC, profiles and pipes, are facing great pressure. In addition to demand issues, they also face industry competition, so the industry's contribution is difficult to improve. The real - estate sector still provides negative demand feedback, and the domestic demand has not shown obvious improvement. The downstream orders are significantly lower than the average level of the past five years, and both raw material and finished product inventories are at high levels, so the PVC downstream is expected to lack positive drivers [93]. Inventory - The total PVC inventory is still at the highest level in recent years compared to the same period [101]. Export - In October 2025, the PVC export volume was 312,100 tons, with an average export price of 605 US dollars/ton. The cumulative export from January to October was 3.2338 million tons. The single - month export decreased by 9.91% month - on - month, increased by 34.28% year - on - year compared to the same month last year, and the cumulative export increased by 48.88% year - on - year. In October 2025, the PVC import volume was 10,900 tons, with an average import price of 725 US dollars/ton. The cumulative import from January to October was 186,400 tons. The single - month import decreased by 24.14% month - on - month, increased by 20.66% year - on - year compared to the same month last year, and the cumulative import increased by 1.74% year - on - year [119].

1. Report Industry Investment Rating No information about the industry investment rating is provided in the report. 2. Core Views of the Report - **Caustic Soda**: The caustic soda industry still faces certain supply - demand pressures. With fewer maintenance enterprises, the total supply shows an increasing trend. The price of alumina, the main downstream product, continues to weaken, and the industry's profit keeps shrinking with increasing losses. Thus, the support from the main demand side of caustic soda is weak, suppressing the price. In the short term, the caustic soda price lacks support. Although the middle and lower reaches may have phased replenishment needs after consuming their own inventories, the price is still under pressure due to increased supply and weak demand. The non - aluminum market remains sluggish. It is expected that the caustic soda price will run weakly in the short term, and a bearish trend is advised, while tracking the downstream replenishment rhythm [2]. - **PVC**: The contradiction of oversupply has not improved. The pressure on the supply side continues to rise, the demand expectation weakens, and the cost - side support is insufficient. There is no positive macro - level expectation for the time being. Therefore, the price is expected to continue to decline. The main downstream fields such as real estate are still weak. The new orders of profile and pipe product enterprises are limited, mainly for rigid - demand procurement, which is difficult to provide continuous support to the market. There will still be an impact from new production capacity on the supply side from November to December. The demand from November to January of the next year is in the traditional off - season, and the overall real - estate demand will decrease, forming a negative impact. Regarding exports, the anti - dumping tax in India is unclear, and exports are mainly on hold. The supply - demand is still in an oversupply pattern, and it is difficult to be optimistic about the price. Although the absolute price is low, it is difficult to form an upward driving force, and it is expected to continue the downward trend at the bottom [3]. 3. Summary by Relevant Catalogs Caustic Soda - **Price and Market Situation**: The caustic soda price is affected by multiple factors such as macro - environment, alumina demand, and cost. The price has shown fluctuations, with periods of decline due to factors like increased supply and weak downstream demand, and short - term rebounds due to factors such as policy expectations and increased demand from alumina [6]. - **Supply**: The national average weekly weighted operating load rate of sample enterprises is 85.55%, a 0.1 - percentage - point increase from last week. The caustic soda output in terms of 100% strength this week is 82.53 tons, a 0.12% increase from last week. There are many ongoing maintenance of chlor - alkali plants this week, but some enterprises with under - capacity operation have increased their loads, resulting in a slight increase in output [25]. - **Alumina Demand**: From the end of 2024 to 2025, the planned production capacity of alumina is 12.3 million tons (including 2 million tons of replacement), and the estimated annual production capacity growth rate is around 10%. The estimated annual output of alumina in 2025 is over 88 million tons, with a production growth rate of around 6%. The new alumina projects will increase the demand for caustic soda by about 800,000 tons per year, with a relatively concentrated increase of 150,000 tons from April to June [30]. - **Alumina Market**: Although the operating rate of some alumina enterprises in the north has decreased recently, the domestic supply - demand contradiction has not been effectively resolved, and the social inventory of alumina continues to increase. It is expected that the domestic alumina price will continue to run weakly in the short term, with a price range of 2,750 - 2,950 yuan/ton [34]. - **Bauxite**: The bauxite price is stable, the port inventory fluctuates, and the enterprise raw - material inventory has increased significantly [38]. - **Electrolytic Aluminum**: In October, the electrolytic aluminum production remained at a high level, and the in - plant inventory of electrolytic aluminum decreased [44]. - **Non - Aluminum Downstream**: The operating rate of the printing and dyeing and textile industries has increased seasonally, and it is in the peak season. However, the overall non - aluminum downstream has not shown strong driving forces [49]. - **Caustic Soda Export**: In September, the export profit of caustic soda increased, and the export volume rebounded significantly. It is estimated that the export profit will decline in October [54]. PVC - **Price and Market Situation**: The PVC price has been on a downward trend due to the lack of positive supply - demand drivers and a poor commodity atmosphere. The price has been affected by factors such as macro - sentiment, supply - demand changes, and export conditions, with periods of sharp declines and short - term rebounds [61]. - **Profit**: The PVC industry has been in a state of continuous losses, with losses in both the calcium - carbide and ethylene - based production methods [67]. - **Calcium Carbide**: The calcium carbide production has increased month - on - month, but the profit has weakened [72]. - **Supply**: The operating load rate of the domestic PVC powder industry has increased this week. Although there are 4 new enterprises for maintenance or shutdown, the overall maintenance loss has decreased, and the industry operating rate has increased. The overall operating load rate of PVC powder this week is 79.28%, a 2.19 - percentage - point increase from last week [83]. - **Downstream Demand**: The two major downstream industries of PVC, profiles and pipes, face great pressure. The real - estate sector, with the goal of "de - inventorying and stabilizing prices", will continue to have a negative impact on demand. The domestic demand has not improved significantly, and it is expected that the PVC downstream will not have positive drivers [93]. - **Real - Estate Data**: The real - estate industry is still in the bottom - building cycle, with indicators such as housing sales price index, land transaction area, and new - construction area showing weak performance [94]. - **Inventory**: The PVC inventory has remained flat recently, and the total inventory is at the highest level in recent years compared year - on - year [101]. - **External Market**: The external market price of PVC has weakened, and the export situation is affected by factors such as anti - dumping taxes in India [108]. - **Export**: In September 2025, the PVC import volume was 14,400 tons, and the export volume was 346,400 tons. The export volume has increased significantly both month - on - month and year - on - year [119].

Group 1 - The domestic PVC powder market shows a strong price adjustment today, with mainstream market prices increasing by 0-15 yuan/ton [1] - The overall operating rate of PVC powder this week is 75.14%, a decrease of 5.66 percentage points from last week [2] - Social inventory of PVC as of October 9 has increased by 5.58% to 1.0363 million tons, with a year-on-year increase of 23.53% [2] Group 2 - Supply and demand pressures remain significant, with both futures and spot prices trending weakly [3] - The demand side shows no significant performance during the peak season, indicating a lack of robust demand from downstream product companies [3] - Cost factors indicate that the price of raw material calcium carbide is expected to rise initially and then fall, while ethylene prices may remain firm [3]

Report Industry Investment Rating - Not provided Core View of the Report - The fundamentals of PVC are expected to improve, and the price is likely to continue its low-level rebound. The cost support has improved due to the firm performance of calcium carbide prices, and the supply pressure is expected to ease as more maintenance plans are scheduled for October. Although exports are affected by policies, the growth rate remains strong. The inventory structure of the industrial chain is differentiated, and the spot price is firm. With the strengthening of the basis, the risk-free arbitrage space in the industry has disappeared, and the hedging pressure has decreased [4]. Summary of Each Section PVC Market Review - This week, PVC fluctuated and rose. It opened higher on Monday at 4883 (up 12 points or 0.24% from last week's close), fell slightly to the daily low of 4863, and then rose strongly. It reached a new monthly high of 4994 on Wednesday morning before falling slightly, and finally closed at 4950 (up 74 points or 1.48% from last week's close). The weekly range was between 4863 and 4994, with an amplitude of 131 points [8]. - As of Friday, the closing price of the PVC01 contract was 4950 yuan/ton (weekly increase of 74 yuan). The main position of PVC was 1.13 million lots, and the market sentiment improved, leading to a rebound with reduced positions [11]. - As of Friday, the PVC basis in Changzhou was -170 yuan/ton, and both the futures and spot prices strengthened slightly. The PVC warehouse receipts were 110,000 lots (weekly decrease of 10,000 lots) [13]. - As of Friday, the V1 - 5 spread was -303 yuan/ton (unchanged), and the V3 - 5 spread was -226 yuan/ton (increase of 10 yuan) [16]. - This week, the price difference between ethylene - based and calcium carbide - based PVC in East China was 223 yuan/ton (decrease of 70 yuan) [19]. Supply - The intensity of device maintenance increased, and the output declined from a high level. This week, the PVC output was 460,000 tons (a decrease of 18,000 tons from the previous week), and the capacity utilization rate was 77%. The cumulative output from week 1 to 38 increased by 4.3% year - on - year [22]. - Next week, the capacity utilization rate of Chinese PVC is expected to be 78%, higher than the current level. The maintenance of Gansu Jinchuan and Zhongtai Shengxiong plants will end, and there are no new enterprises joining the maintenance, so the overall supply is expected to increase [22]. Real Estate - From January to August 2025, the cumulative year - on - year changes in the new construction, construction, completion, and sales areas of real estate were -19.5%, -9.3%, -17.0%, and -4.7% respectively, with the decline rates expanding. In August 2025, the cumulative year - on - year changes were -19.8%, -28.6%, -21.3%, and -11.0% respectively, and the decline rate of sales area has been expanding for 5 consecutive months. In August 2025, the year - on - year change of the new commercial housing price index in 70 large and medium - sized cities was -2.95% [25]. - This week, the commercial housing transaction area in 30 cities was 2.2 million square meters [28]. Domestic Demand - This week, the downstream operating rate was 49%, increasing for 3 consecutive weeks and exceeding the level of the same period last year. Among them, the operating rate of pipes has increased significantly in the past two weeks [30]. Exports - From January to August 2025, the PVC export volume was 2.57 million tons (an increase of 910,000 tons year - on - year), with a cumulative year - on - year increase of 55%.

Inventory - As of Thursday this week, the inventory of PVC enterprises was 310,000 tons (a decrease of 4,000 tons from the previous week), with inventory reduction for 2 consecutive weeks. The pre - sales volume of upstream enterprises was 756,000 tons (an increase of 70,000 tons from the previous week), at a high level in the same period. The PVC price fluctuated slightly this week, and manufacturers sold goods with price support and delivered some export orders. It is expected that the in - stock inventory of PVC enterprises will decrease slightly next week [39]. - As of Thursday this week, the small - sample social inventory of PVC was 530,000 tons (an increase of 3,000 tons from the previous week), and the inventory accumulation speed slowed down. The large - sample social inventory was 950,000 tons (an increase of 19,000 tons from the previous week), with inventory accumulation for 13 consecutive weeks and a total inventory accumulation of 365,000 tons [41]. Profit - This week, the gross profit of calcium carbide - based PVC was -502 yuan/ton (a decrease of 81 yuan from the previous week), with profit contraction for 3 consecutive weeks [44]. - This week, the gross profit of ethylene - based PVC was -672 yuan/ton, with profit contraction for 6 consecutive weeks [47].

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints - PVC is in a phase of oscillating downward, and the later price center is expected to decline. The supply of PVC continues the weak trend, with high - yield production maintained. Domestic and export demands are weakening, and social inventory is continuously accumulating. However, recently, as coal prices strengthen, the cost - chain support of coal - based production has strengthened, which may limit the downward space [6]. 3. Summaries According to Related Catalogs 3.1 Fundamental Supply and Demand Supply - The risk lies in the possible upward shift of the entire industrial chain price from coal to calcium carbide if coal prices rise in the future, and the cost - side support is expected to strengthen [9]. - In 2025, the first - quarter has seen a new production capacity of 500,000 tons. Fujian Wanhua's 500,000 - ton capacity was put into production on August 2, and the annual production capacity growth rate is expected to be 6.37%. The pressure of production capacity release remains high. - On August 8, the overall operating load rate of PVC powder was 77.75%, a 4.49% increase from the previous period (due to planned maintenance). The annual cumulative production is expected to have a year - on - year growth rate of 3.23% [13]. Demand - **Domestic demand**: The current downstream operating rate is at a low level compared to the same period last year, especially for pipe enterprises. Domestic downstream product enterprises continue to purchase at low prices and resist high - priced raw materials. There is a seasonal weakening due to high - temperature in summer [10]. - **Export**: On August 8, the export order volume sample of PVC production enterprises decreased by 5.08% compared to the previous period and increased by 1.89% year - on - year [14]. Inventory - As of August 8, the total inventory of the original sample warehouses in East and South China was 457,600 tons, a 7.44% increase from the previous period and a 14.74% decrease year - on - year. The total inventory of the expanded sample warehouses in East and South China was 718,400 tons, a 6.73% increase from the previous period and an 18.35% decrease year - on - year [11]. 3.2 Disk Data - The PVC price was oscillating this week, mainly due to the game between cost and supply - demand. In terms of supply - demand, the supply remained high, new production capacity was yet to be fully released, while the downstream was still in the off - season, social inventory continued to increase, and registered warehouse receipts also increased. However, on the cost side, driven by the rise in coal prices, semi - coke enterprises raised prices, and the supply of calcium carbide enterprises decreased under the influence of power restrictions, leading to an increase in the cost of the industrial chain. - The basis was at a discount to the disk. This week, the East China 09 basis was around - 200; the 9 - 1 spread was weakly running at - 140. - The position of the 09 contract decreased to around 635,000 lots, and the warehouse receipts increased to around 63,200 lots [21]. 3.3 Regional and Quality Spreads - **Regional spread**: The spread between East and South China's calcium - carbide - based PVC weakened to - 127, and the spread between East and North China's calcium - carbide - based PVC weakened to - 27. - **Ethylene - calcium carbide spread**: The ethylene - calcium carbide spread oscillated around 307 [33]. 3.4 Profit Performance - **Calcium - carbide - based profit**: The current calcium - carbide - based production capacity accounts for 74%. The comprehensive profit of calcium - carbide - based production has shrunk, mainly because the cost has strengthened while the PVC spot price has been weakly oscillating. - For northwest integrated enterprises, the price of semi - coke, a cost factor, increased slightly this month, and the comprehensive profit decreased slightly to around 500 yuan/ton. - For enterprises purchasing calcium carbide, the price of calcium carbide increased this week. The comprehensive profit of northwest enterprises purchasing calcium carbide decreased to around 800 yuan/ton, and the comprehensive profit of chlor - alkali enterprises in Shandong was compressed to near the break - even point [43][44]. - **Ethylene - based profit**: The current ethylene - based production capacity accounts for about 23.5% (excluding coal - to - methanol - to - ethylene). The adjustment range of the ethylene - based PVC spot price was limited. The profit of enterprises purchasing vinyl chloride was slightly profitable, while the profit of enterprises purchasing ethylene was a loss of 100 yuan/ton [45]. 3.5 Industry - related Product Situation Semi - coke - This week (August 8), the semi - coke price increased slightly. The medium - grade semi - coke in the Shaanxi market was traded at 620 - 650 yuan/ton. The cost pressure of semi - coke production enterprises remained under the firm coal price, and the production enthusiasm of most enterprises was average. Some enterprises had limited inventory, which supported a narrow increase in the ex - factory price, and the price remained stable after the increase. Downstream users mainly purchased on - demand, and the enthusiasm for inventory replenishment was not high. The limestone price remained stable, and the mainstream ex - factory price in Wuhai was 55 - 70 yuan/ton. - On August 8, the operating rate of semi - coke sample enterprises was 54.22%, a 0.57% increase from the previous period. - In the future, the coal consumption of downstream power plants may increase due to high - temperature in August, and the cost pressure will still exist. In addition, the demand for small - sized semi - coke and foreign trade orders are expected to increase, so semi - coke still has room for improvement. The trend of coal prices and the inventory of semi - coke enterprises need to be monitored [66]. Calcium Carbide - This week (August 8), the overall price of calcium carbide shifted upward. The market price of calcium carbide in Wuhai increased from 2,250 yuan/ton to 2,340 yuan/ton, a 90 - yuan increase from the previous week. The supply decreased due to maintenance or peak - shaving production, and the price center of calcium carbide in most northwest regions shifted upward. The purchase prices in central and northern China remained stable. - On August 8, the average operating load rate of the calcium carbide industry decreased to 68.89%, a 3.94% decrease from the previous period. One reason is the unstable power supply in Inner Mongolia, and some calcium carbide plants in Wuhai were affected by peak - shaving production. The other reason is that some calcium carbide plants in Ningxia and Gansu were affected by the increase in electricity prices and carried out maintenance or peak - shaving production. - In the future, some affected calcium carbide plants this week are expected to resume production, but the increase in the operating rate may be limited due to peak - shaving production in Inner Mongolia. During the peak electricity - consumption season in August, the operating rate may be unstable. On the demand side, the demand for calcium carbide from PVC plants increased in the first half of August but is expected to be limited in the second half. The semi - coke price may be firm, and the impact of coal - related policies needs to be monitored. Overall, the supply - demand support for calcium carbide is relatively limited, but if the supply decreases more than expected due to peak - shaving production or if the coal price increase is transmitted to the entire coal - based cost chain, the calcium carbide price may rebound [70][75]. Caustic Soda - This week (August 8), the caustic soda market changed little. The price of 32% ionic membrane caustic soda decreased by 10 - 60 yuan/ton in some areas and increased by 10 - 110 yuan/ton in others. The non - aluminum demand in Shandong, Hebei, and South China was weak during the off - season, and the mainstream transaction price center shifted downward. The price in the southwest region increased slightly due to plant maintenance. - On August 8, the weekly operating rate of the caustic soda sample was 85.1%, a 1.2% increase from the previous period, and the weekly inventory was 461,700 tons, an 8.84% increase from the previous period. - In the future, most chlor - alkali enterprises will operate normally, with sufficient supply. During the off - season, downstream users will mainly purchase on - demand. The overall price may be weak, but the price in some areas may increase slightly due to maintenance and low inventory [80]. 3.6 Supply - **Production capacity growth**: The production capacity growth rate in the third quarter is 3.18%, and the annual growth rate is expected to be 6.37%. Fujian Wanhua's 500,000 - ton capacity was put into production on August 2, Bohua Development's 400,000 - ton ethylene - based plant was tested in July and is expected to be in full production in August. Qingdao Gulf's 200,000 - ton ethylene - based plant is planned to be put into production in the third quarter; Jiahua Energy's 300,000 - ton plant is planned for the third or fourth quarter, and other plants may be postponed. The annual production capacity growth rate may be around 6.4%, and the relatively certain growth rate in the third quarter may be 3.18% (900,000 tons/28.33 million - ton capacity) [84]. - **Operation and maintenance**: The theoretical loss due to shutdown and maintenance this week (including long - term shutdown enterprises) was 54,240 tons, a decrease of 27,180 tons from the previous week. Only Ordos No. 2 Factory is planned to be under maintenance next week, and some previously maintained enterprises may resume production. The maintenance loss is expected to decrease next week. The annual cumulative production is expected to have a year - on - year growth rate of 3.23%. The risk is that the upward shift of the entire industrial chain price from coal to calcium carbide may strengthen the cost support [85]. 3.7 Import and Export - In June 2025, the PVC import volume was 24,000 tons, a 63.80% increase from the previous month. The cumulative import from January to June was 124,300 tons, a 32.61% increase from the same period last year, and the cumulative year - on - year growth rate was 0.51%. The import sources are mainly the United States and Northeast Asia regions, and the import remains at a low level, with an import dependence of about 1%. - In June 2025, the PVC export volume was 262,000 tons, a 27.61% decrease from the previous month. The cumulative export from January to June was 1.9606 million tons, a 21.03% increase from the same period last year, and the cumulative year - on - year increase was 50.20%. The main destination is still India. - In June 2025, the export volume of Chinese PVC floor materials was 323,600 tons, an 8.09% decrease from the previous month. The cumulative export volume from January to June was 2.091 million tons, an 11.14% decrease from the same period last year. The main destinations are the United States and Canada [113]. 3.8 Downstream Demand - The current downstream operating rate is at a low level compared to the same period last year, especially for pipe enterprises. Domestic downstream product enterprises continue to purchase at low prices and resist high - priced raw materials. There is a seasonal weakening due to high - temperature in summer [136]. - **Real estate**: From January to June, the cumulative year - on - year decline in real estate investment was 11.2%, and the decline slightly expanded; the cumulative year - on - year decrease in new construction area was 20%. The investment confidence has not recovered, and the willingness to start construction is poor. The front - end indicators such as investment, new construction, construction, and completion all showed significant year - on - year declines, indicating that the capital pressure of real estate enterprises has not been substantially relieved, and the development willingness remains weak. Although the decline in the sales end has narrowed, a 3.5% year - on - year decline still shows that the recovery momentum of the demand end is insufficient, and there is a time lag in the transmission of policy relaxation to the market. The real estate market may still be in a downturn, and the demand for PVC may continue to shrink [155][156]. 3.9 Inventory - On August 8, some production enterprises tried to maintain prices, the arbitrage space for traders was limited, and the procurement enthusiasm of hedgers was average. Some factories received fewer orders. Some enterprises had high pre - sales in the previous period and mainly delivered previous orders this week. The salable inventory of sample production enterprises increased compared to the previous period, reaching 496,500 tons, an increase of 42,150 tons. The factory inventory of sample production enterprises decreased slightly compared to the previous period, reaching 327,250 tons, a decrease of 13,430 tons. - As of August 8, due to the decrease in maintenance on the supply side of domestic PVC, the increase in operation, and the normal market arrival, the market price first decreased and then increased, and the downstream's enthusiasm for receiving orders was poor. The total inventory in East and South China continued to increase. As of September 1, the original sample inventory in East China was 405,000 tons, a 7.31% increase from the previous period and an 18.58% decrease year - on - year. The expanded sample inventory in East China was 665,800 tons, a 6.60% increase from the previous period and a 20.76% decrease year - on - year. The sample inventory in South China was 52,600 tons, an 8.45% increase from the previous period and a 32.83% increase year - on - year. The total inventory of the original sample warehouses in East and South China was 457,600 tons, a 7.44% increase from the previous period and a 14.74% decrease year - on - year. The total inventory of the expanded sample warehouses in East and South China was 718,800 tons, a 6.73% increase from the previous period and an 18.35% decrease year - on - year [171].

Report Industry Investment Rating - The short - term trend rating for PVC is "oscillating", with an amplitude of - 5% - + 5% [5] Report's Core View - Currently, the supply - demand situation of PVC has weakened month - on - month, but the strong policy expectations have reversed the market's overly pessimistic sentiment, driving the futures price to rise significantly. However, the price increase has not yet significantly affected the supply - demand relationship, as marginal production capacity is still in a loss state. If the futures price rises to 5300 - 5400 yuan/ton, marginal production capacity may turn profitable, and supply may increase marginally. Also, the 09 basis has reached the risk - free arbitrage level, and sufficient spot inventory and available warehouse capacity will attract more hedging positions if the price continues to rise. In the current strong commodity market sentiment, the PVC futures price may remain strong in the short term, but it is likely to fall from its high if there is no clear short - term policy implementation plan or if the overall commodity market sentiment calms down [3][18] Summary by Relevant Catalogs 6 - month - on - month Weakening of PVC Fundamentals - Since June, with the end of spring maintenance, PVC supply has increased month - on - month. As Southeast Asia and India enter the rainy season, China's PVC exports have weakened significantly in June. Since mid - June, PVC social inventory has shifted from continuous depletion since the end of February to continuous accumulation, indicating a significant month - on - month weakening of PVC fundamentals [1][8] Unclear Supply - side Policy Implementation Rules and Few Old PVC Devices - There are no official and enforceable rules for anti - involution and old device transformation policies in the PVC industry. Although some marginal PVC production capacity is in a loss state, most northwest calcium carbide - based PVC enterprises are profitable, and leading enterprises have little motivation for anti - involution. According to statistics, PVC devices with an operation time of over 20 years have a total capacity of 218 million tons per year, accounting for only 7.6% of the total capacity, and 35 million tons per year of them are in long - term shutdown. The overall PVC industry devices are relatively new due to self - initiated capacity clearance from 2013 - 2015 and the clearance of high - cost calcium carbide - based devices in recent years. The current rise in the PVC futures price is more due to sentiment rather than an actual improvement in supply - demand [2][14] Investment Advice - Fundamentally, the current supply - demand of PVC has weakened month - on - month, but strong policy expectations have reversed the market's pessimistic sentiment and pushed up the futures price. The current price increase has not significantly affected the supply - demand relationship as marginal production capacity is still in a loss state. If the futures price rises to 5300 - 5400 yuan/ton, marginal production capacity may turn profitable, and supply may increase marginally. The 09 basis has reached the risk - free arbitrage level, and sufficient spot inventory and available warehouse capacity will attract more hedging positions if the price continues to rise, which is why the number of warehouse receipts has increased rapidly recently. In the current strong commodity market sentiment, the PVC futures price may remain strong in the short term, but it is likely to fall from its high if there is no clear short - term policy implementation plan or if the overall commodity market sentiment calms down [3][18]
