Report Summary 1. Report Industry Investment Rating - Not provided in the report 2. Core Viewpoints - V2601 oscillated weakly, closing at 4999 yuan/ton. This week, the restart of maintenance devices is expected to increase production and capacity utilization, while more PVC production plans in August will add long - term supply pressure. Domestic product orders are insufficient, and downstream enterprises mainly purchase at low prices. The weak real estate market drags down domestic demand, and the Indian anti - dumping policy will exacerbate the supply - demand contradiction and put pressure on prices. Technically, V2601 should pay attention to the support around 4900 and the pressure around 5100 [3] 3.

Group 1 - The global PVC market is facing challenges in the second half of 2025 due to demand growth not keeping pace with capacity expansion, particularly in Asia [2] - The impact of US tariffs on PVC products is exacerbating the weak fundamentals of the PVC market [2] - India's PVC market is under scrutiny due to delayed import certification requirements and an impending anti-dumping tax investigation, which may alter regional trade flows [2][3] Group 2 - In Asia, PVC production capacity continues to increase despite weak demand, leading manufacturers to consider reducing operating rates to address oversupply [3] - The postponement of BIS certification in India may lead to a potential recovery in PVC demand, but there are mixed opinions on its impact on pricing and trade flows [3] - Qatar's new PVC plant is expected to start production in September, with Europe likely being the main export market due to higher profit margins compared to India [3] Group 3 - The European PVC market may see more shutdowns in the second half of 2025 due to persistent weak demand and competitive import prices, particularly affecting smaller, less integrated PVC plants [4] - Germany may show positive signs with a government commitment of €500 billion for infrastructure and climate transition, which could boost PVC demand [4] - Traders are expected to continue exporting Asian goods to Europe, with Italy and Spain remaining key markets for Asian supplies [4] Group 4 - The US PVC market outlook is mixed, facing challenges from strong Asian price competition and a sluggish domestic housing market [5] - The export prices of PVC from Asia and the US are closely aligned, leading to direct competition in the global import market [5] - Brazil's import tariffs have shifted the competitive landscape, resulting in decreased export volumes from both the US and Asia [5]

1. Report Industry Investment Ratings - The investment rating for caustic soda is bullish, while for PVC it is bearish [1] 2. Core Views of the Report - **Caustic Soda**: The current core driver of the caustic soda market is the continuous expansion of demand. With the increasing rigid demand and inventory - building demand from alumina, especially the expected 3.6 million - ton alumina capacity to be put into production in Guangxi by the end of this year, the supply of caustic soda in Guangxi is tight. The export support is still strong, and the downstream peak - season restocking is likely to drive the spot price upwards. Although the weakness of chlorine - consuming downstream industries such as PVC may limit the overall industry profit expansion, the overall view is to maintain a bullish attitude [5] - **PVC**: In 2025, the high - production structure of PVC is difficult to change in the short term, and there will be more new capacity put into production in the future. The export market competition pressure increases, and the domestic demand related to the real estate industry is still weak. The anti - dumping tax from India will limit the export to India, and the market will continue to short PVC profits. The overall trend is bearish [7] 3. Summary According to the Table of Contents 3.1 Viewpoint Overview - **Caustic Soda**: The supply side shows that the average utilization rate of the production capacity of Chinese caustic soda sample enterprises with a capacity of 200,000 tons or more is 84.1%, a week - on - week decrease of 1.0%. The demand side is strong, with alumina having high production willingness and strong demand for caustic soda. The export support is also strong. The overall view is to maintain a bullish attitude, with specific strategies including holding long positions in contracts 10 and 11, conducting positive spreads in 10 - 1 and 11 - 1, and going long on caustic soda and short on PVC [5] - **PVC**: The high - production situation is difficult to change in the short term, and there will be new capacity put into production in the future. The export market competition pressure increases, and the domestic demand related to real estate is weak. The anti - dumping tax from India will limit exports. The overall trend is bearish, with strategies including shorting on rallies, not participating in inter - period spreads, and going long on caustic soda and short on PVC [7] 3.2 Caustic Soda Price and Spread - The price of the cheapest deliverable caustic soda in Shandong is about 2,562 yuan/ton. The basis of caustic soda 09 changes little, and the 10 - 1 month spread is strong. The export market still has support, with the cumulative export from January to June 2025 reaching 2.03 million tons, a year - on - year increase of 49.3%. The regional arbitrage space is limited, but attention should be paid to the continuous expansion of the flake caustic - liquid caustic spread. The 50% - 32% caustic soda spread is lower than the evaporation cost, which is bearish for caustic soda [10][16][22] 3.3 Caustic Soda Supply - The market structure shows a decline in production and inventory, with a strong structure. The average utilization rate of the production capacity of Chinese caustic soda sample enterprises with a capacity of 200,000 tons or more is 84.1%, a week - on - week decrease of 1.0%. The factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons or more is 437,800 tons (wet tons), a week - on - week decrease of 5.18% and a year - on - year increase of 18.61%. Attention should be paid to the maintenance scale from August to September. The actual capacity expansion of caustic soda in 2025 will be weaker than expected, with a capacity increase of about 2%. The cost side of caustic soda changes greatly, and the recent rebound of liquid chlorine leads to a good overall profit situation [39][40][42] 3.4 Caustic Soda Demand - Alumina shows an increase in production, inventory, and stable profits. The key in the second half of the year is whether the alumina production can drive a new round of demand expansion. The pulp industry has continuous capacity expansion, but the terminal demand is in the off - season. The finished paper industry has a low year - on - year start - up rate. The viscose staple fiber, printing and dyeing, water treatment, and ternary precursor industries all have stable starts [79][86][96] 3.5 PVC Price and Spread - The PVC basis fluctuates strongly, and the 9 - 1 month spread fluctuates weakly [109] 3.6 PVC Supply and Demand - The PVC start - up rate increases month - on - month, with great supply pressure. There will be seasonal maintenance in the northwest from August to September 2025, and there is still a lot of new capacity to be put into production. The northwest integrated device has a good profit, and the profit of caustic soda should be particularly concerned in 2025. PVC production enterprises are destocking, while social inventory is accumulating. The real - estate terminal demand has not significantly recovered, and the start - up rates of PVC downstream pipes, profiles, and films are generally weak year - on - year. The PVC export is expected to weaken, and a large amount of risk - free arbitrage may lead to a large increase in warehouse receipts in the later stage [113][115][123]

Report Summary 1. Report Industry Investment Rating No investment rating information is provided in the report. 2. Core Viewpoints - The PVC industry is currently facing a situation of strong supply, weak demand, and high valuation. The fundamentals are poor, and it is necessary to observe whether subsequent exports can exceed expectations to reverse the domestic inventory accumulation pattern. In the short term, prices have fallen sharply after the anti - involution sentiment subsided. In the medium term, if there is no policy for device clearance, the supply - demand pattern will remain weak, and the industry still faces the pressure of de - valuing to clear excess capacity [11]. 3. Summary by Directory 3.1 Monthly Assessment and Strategy Recommendation - **Cost and Profit**: The price of Wuhai calcium carbide is 2,340 yuan/ton, a monthly increase of 90 yuan/ton; Shandong calcium carbide is 2,780 yuan/ton, a monthly decrease of 75 yuan/ton; and Shaanxi medium - grade semi - coke is 620 yuan/ton, a monthly decrease of 10 yuan/ton. The comprehensive profit of chlor - alkali integration first soared and then declined, and the profit from ethylene production remained low, with weak valuation support [11]. - **Supply**: The PVC capacity utilization rate is 79.5%, a monthly increase of 2%. Among them, the calcium carbide method is 78.7%, a monthly decrease of 2.2%, and the ethylene method is 81.5%, a monthly increase of 13%. Last month, the maintenance volume was high, and the average capacity utilization rate was lower than that in June, with reduced supply pressure. This month, the maintenance intensity is lower than last month, and the newly - put - into - production devices are gradually releasing output, so the supply pressure is expected to increase significantly [11]. - **Demand**: In terms of exports, there was a high export growth rate in the first five months. In June, with the rainy season in Southeast Asia and the uncertainty of export policies to India, overall exports declined significantly. Currently, both India's BIS policy and anti - dumping policy have been extended, improving the weak outlook for the second half of the year. Attention should be paid to whether there will be a rush to export at the end of the rainy season. The operating rates of the three major downstream industries stopped falling and rebounded. The pipe load is 32.1%, a monthly decrease of 7.4%; the film load is 76.9%, a monthly increase of 4.7%; the profile load is 36.9%, a monthly increase of 2.2%. The overall downstream load is 42.9%, the same as last month. The overall downstream performance is worse than the same period last year, and the overall demand is weak. The main incremental demand depends on exports [11]. - **Inventory**: At the end of the month, the in - factory inventory was 33.7 tons, a monthly decrease of 4.9 tons; the social inventory was 77.7 tons, a monthly increase of 18.5 tons; the overall inventory was 111.4 tons, a monthly increase of 13.6 tons; and the warehouse receipts continued to rise. Currently, it has entered the inventory accumulation cycle, and the upstream inventory is gradually transferred to the middle - stream. In the pattern of strong supply and weak demand, if the export end does not perform better than expected, inventory accumulation will continue [11]. 3.2 Cost End - The price of calcium carbide in Wuhai is 2,340 yuan/ton, a monthly increase of 90 yuan/ton; the price of calcium carbide in Shandong is 2,780 yuan/ton, a monthly decrease of 75 yuan/ton; and the price of Shaanxi medium - grade semi - coke is 620 yuan/ton, a monthly decrease of 10 yuan/ton. The semi - coke price has stabilized, and caustic soda is weak [11][49]. 3.3 Supply End - In 2025, the capacity investment in the PVC industry is relatively large, mainly concentrated in the third quarter. New capacity of 250 tons/year is expected to be put into production, including 100 tons/year of ethylene - based and 150 tons/year of calcium - carbide - based. The newly - put - into - production devices include those of Xinsheng Chemical, Jintai Chemical, Wanhua Chemical (Phase II), Tianjin Bohua, Zhejiang Jiahua, Qingdao Gulf, and Gansu Yaowang [58][63]. 3.4 Demand End - The operating rates of the three major downstream industries (pipes, films, and profiles) of PVC stopped falling and rebounded. In terms of exports, there was a high growth rate in the first five months, but it declined significantly in June. With the extension of India's anti - dumping policy, there may be a rush to export at the end of the rainy season. The overall downstream demand is weak, and the main incremental demand depends on exports [11].

Report Industry Investment Rating - Not provided in the document Core Viewpoints of the Report - The supply pressure of PVC increased this week, and the expected production schedule is likely to increase significantly next week as maintenance is expected to decrease. The current demand may remain sluggish, and the overall inventory is at a high level. The PVC2509 contract is expected to fluctuate in the range of 4988 - 5104. The main logic is that the overall supply pressure is strong, and the domestic demand recovery is sluggish [7][8][9]. - The positive factors include supply resumption, cost support from calcium carbide and ethylene, and export benefits. The negative factors are the rebound of overall supply pressure, high - level and slow - consuming inventory, and weak domestic and foreign demand [12]. Summary According to Relevant Catalogs 1. Daily Viewpoints - **Base Spread**: On August 7th, the price of East China SG - 5 was 4980 yuan/ton, and the basis of the 09 contract was - 66 yuan/ton, with the spot at a discount to the futures, showing a bearish signal [10]. - **Inventory**: The factory inventory was 34534 tons, a month - on - month decrease of 3.28%. The calcium carbide factory inventory was 26919 tons, a month - on - month decrease of 3.12%, and the ethylene factory inventory was 7615 tons, a month - on - month decrease of 3.85%. The social inventory was 44800 tons, a month - on - month increase of 4.91%. The inventory days of production enterprises was 5.8 days, a month - on - month decrease of 3.33%, all indicating a bearish situation [10]. - **Market Chart**: The MA20 was upward, and the futures price of the 09 contract closed below the MA20, showing a neutral signal [10]. - **Main Position**: The main position was net short, and the short position decreased, indicating a bearish signal [10]. 2. Fundamental/Position Data Supply Side - In July 2025, the PVC production was 2.00461 million tons, a month - on - month increase of 0.67%. This week, the capacity utilization rate of sample enterprises was 76.84%, with no change from the previous week. The production of calcium carbide enterprises was 32458 tons, a month - on - month decrease of 4.06%, while the production of ethylene enterprises was 12770 tons, a month - on - month increase of 12.82%. The supply pressure increased this week, and the production schedule is expected to increase significantly next week as maintenance is expected to decrease [7]. Demand Side - The overall downstream operating rate was 42.05%, a month - on - month increase of 0.169 percentage points, lower than the historical average. The downstream profile operating rate was 37%, a month - on - month decrease of 1 percentage point, lower than the historical average. The downstream pipe operating rate was 32.96%, a month - on - month increase of 0.439 percentage points, lower than the historical average. The downstream film operating rate was 77%, unchanged from the previous week, higher than the historical average. The downstream paste resin operating rate was 70.82%, a month - on - month decrease of 5.25 percentage points, higher than the historical average. Shipping costs are expected to rise, and the domestic PVC export price is competitive. The current demand may remain sluggish [8]. Cost Side - The profit of calcium carbide method was - 20.9487 yuan/ton, with a month - on - month reduction of losses by 84.00%, lower than the historical average. The profit of ethylene method was - 478.9958 yuan/ton, with a month - on - month reduction of losses by 5.00%, lower than the historical average. The double - ton spread was 2673.25 yuan/ton, with a month - on - month profit decrease of 2.00%, higher than the historical average. The production schedule may increase [8].

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report The PVC industry is currently facing a situation of strong supply and weak demand with high valuations. Fundamentally, the comprehensive profit of enterprises has risen to a high point for the year, but the valuation pressure is significant. In the short term, there is an expectation of supply reduction due to anti - involution and a rebound in the black building materials sector, but there is a risk of a sharp decline after the sentiment fades. In the medium term, the industry is suppressed by large - scale capacity growth and continuous decline in real estate demand. It needs to rely on export growth or the implementation of policies to clear old devices to consume the excess domestic production capacity [11]. 3. Summary According to the Directory 3.1 Week - on - Week Assessment and Strategy Recommendation - **Cost and Profit**: Wuhai calcium carbide price is reported at 2,225 yuan/ton, down 25 yuan/ton week - on - week; Shandong calcium carbide price is reported at 2,780 yuan/ton, down 45 yuan/ton week - on - week; Shaanxi medium - grade semi - coke is at 585 yuan/ton, unchanged week - on - week. The comprehensive profit of chlor - alkali integration has risen to a high point for the year, and the profit of ethylene production has continued to rebound, but the valuation support is currently weak [11]. - **Supply**: The PVC capacity utilization rate is 76.8%, a 0.8% decrease from the previous period. Among them, the calcium carbide method is 79.3%, a 0.5% decrease, and the ethylene method is 70.3%, a 1.7% decrease. The supply load decreased last week due to the maintenance of several enterprises, and it is expected to recover next week. There were more maintenance operations in July than in June, but the supply pressure remains high, and the pressure of new device production in the third quarter is large [11]. - **Demand**: India's anti - dumping policy has been extended to the end of September, alleviating the weak export pressure in the third quarter, with an expectation of pre - tariff export rush. The operating rates of the three major downstream industries have rebounded this week. The overall downstream load is 41.9%, a 1.8% increase from the previous period, but still weak compared to the same period last year. The PVC pre - sales volume last week was 795,000 tons, a 99,000 - ton increase from the previous period [11]. - **Inventory**: Last week, the in - factory inventory was 357,000 tons, a decrease of 10,000 tons from the previous period; the social inventory was 683,000 tons, an increase of 26,000 tons from the previous period; the overall inventory was 1.04 million tons, an increase of 16,000 tons from the previous period; the number of warehouse receipts has increased. In the future, under the pattern of strong domestic supply and weak demand, the supply - demand situation will turn to inventory accumulation, and it is necessary to observe whether the export is better than expected [11]. - **Summary**: Fundamentally, the comprehensive profit of enterprises has risen to a high point for the year, with high valuation pressure. The maintenance volume is gradually decreasing, and the production is at a five - year high. In the short term, multiple sets of devices will be put into production. The domestic downstream operating rate is at a five - year low and still in the off - season. The cost support is weakening. In the medium term, the industry is suppressed by capacity growth and real - estate demand decline. Overall, the fundamentals are poor, and it is necessary to observe whether the subsequent export can reverse the domestic inventory accumulation pattern [11]. 3.2 Futures and Spot Market The report presents multiple charts related to the PVC futures and spot markets, including the term structure, East China SG - 5 price, spot basis, 9 - 1 spread, active contract positions, trading volume, total positions, and total trading volume from 2021 to 2025, but no specific data analysis is provided in the text [16][19][24][26]. 3.3 Profit and Inventory - **Profit**: The profit of chlor - alkali integration has recovered to a high point for the year, with high valuation pressure [37]. - **Inventory**: The report shows multiple charts of PVC inventory, including in - factory inventory, ethylene - based in - factory inventory, calcium - carbide - based in - factory inventory, social inventory, the sum of factory and social inventory, and warehouse receipts from 2021 to 2025 [31][34][36]. 3.4 Cost Side The cost side shows that calcium carbide prices are falling and inventory is accumulating.

Due to the lifting of the ban on US ethane exports to China, domestic ethylene supply tends to be loose, and the cost of ethylene - based PVC may continue to decline in the short term [3].
