1. Report Industry Investment Rating - No relevant content provided. 2. Core View of the Report - From October 24 - 30, the national average capacity utilization rate of caustic soda increased by 3.5% week - on - week to 84.3%. Multiple sets of equipment in East, North, Northwest, South, and Northeast China restarted, leading to a significant increase in supply. The downstream alumina maintained a high - operating state, while the operating rates of viscose staple fiber and printing and dyeing increased slightly. However, due to the obvious increase in supply and general downstream demand, the inventory of liquid caustic soda factories accumulated significantly last week. This week, there are both new maintenance and restart equipment in North and Central China, with the overall capacity utilization rate expected to increase. The supply of downstream alumina is loose and the low - profit situation may continue, suppressing the industry's stocking demand. Non - aluminum downstream industries have rigid demand for procurement with little change. The high inventory of liquid caustic soda in factories increases the pressure on enterprises to sell at low prices. The continuation of high - operating, high - inventory, and weak - demand situations exerts pressure on prices. Technically, SH2601 should pay attention to the support around 2250 [3]. 3. Summary by Relevant Catalogs 3.1 Futures Market - The closing price of the main caustic soda futures contract was 2303 yuan/ton, down 33 yuan; the position of the main caustic soda futures contract was 138,392 lots, an increase of 10,328 lots; the net position of the top 20 futures was - 14,339 lots, an increase of 25 lots; the trading volume of the main caustic soda futures contract was 451,353 lots, an increase of 197,250 lots; the closing price of the January caustic soda contract was 2303 yuan/ton, down 33 yuan; the closing price of the May caustic soda contract was 2481 yuan/ton, down 22 yuan [3]. 3.2 Spot Market - The price of 32% ion - membrane caustic soda in Shandong was 800 yuan/ton, unchanged; in Jiangsu, it was 930 yuan/ton, down 20 yuan.

From October 25 - 31, the national alumina operating rate decreased by 0.41% week - on - week to 85.86%; the viscose staple fiber operating rate increased by 1.03% to 89.64%, and the printing and dyeing operating rate increased by 1.01% to 68.32%. As of October 30, the inventory of liquid caustic soda factories increased by 6.84% week - on - week to 442,600 tons. From October 24 - 30, the chlor - alkali profit rose to 626 yuan/ton [3].

Group 1: Report Overview - The report is the caustic soda industry daily report on October 22, 2025 [1] Group 2: Market Data Futures Market - The closing price of the main caustic soda contract was 2380 yuan/ton, with a 5-yuan increase; the contract closing price of caustic soda for January was 2380 yuan/ton, and for May was 2475 yuan/ton with a 2-yuan increase [2] - The position of the main caustic soda contract was 120124 lots, a decrease of 1434 lots; the trading volume was 252513 lots, an increase of 28850 lots [2] - The net position of the top 20 futures traders for caustic soda was -787 lots, a decrease of 1801 lots [2] Spot Market - The price of 32% ion-exchange membrane caustic soda in Shandong was 820 yuan/ton, and in Jiangsu was 950 yuan/ton, both unchanged [2] - The converted 100% caustic soda price in Shandong was 2562.5 yuan/ton, unchanged; the basis of caustic soda was 188 yuan/ton, a 5-yuan increase [2] Upstream - The mainstream price of raw salt in Shandong and Northwest China was 210 yuan/ton, unchanged; the price of steam coal was 647 yuan/ton, a 3-yuan increase [2] Industry - The mainstream price of liquid chlorine in Shandong was 150 yuan/ton, and in Jiangsu was 100 yuan/ton, both unchanged [2] Downstream - The spot price of viscose staple fiber was 13120 yuan/ton, unchanged; the spot price of alumina was 2830 yuan/ton, a 5-yuan decrease [2] Group 3: Industry News - From October 10th to 16th, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 81.4%, a 2.6% decrease from the previous week [2] - Last week, the capacity utilization rate of alumina decreased by 0.10% to 86.22%, the operating rate of viscose staple fiber decreased by 1.02% to 88.61%, and the operating rate of printing and dyeing increased by 0.63% to 67.26% [2] - As of October 16th, the inventory of liquid caustic soda in sample enterprises was 403,300 tons (wet tons), a 4.25% decrease from the previous week and a 13.83% increase year-on-year [2] - From October 10th to 16th, the average weekly profit of the Shandong chlor-alkali industry was 394 yuan/ton [2] Group 4: Core Views - The SH2601 contract showed a "cross" oscillation and closed at 2380 yuan/ton. Last week, the impact of maintenance devices increased, and the operating rates of caustic soda in North, East, and Northwest China decreased to varying degrees, with the national average operating rate decreasing [2] - The high operating state of downstream alumina continued, and the operating rates of viscose staple fiber and printing and dyeing changed slightly. After the National Day, the inventory of liquid caustic soda factories resumed the destocking trend, but the inventory pressure was still high [2] - Affected by the subsidy from liquid chlorine and the relatively strong market price of liquid caustic soda in Shandong, the profit of the Shandong chlor-alkali industry recovered last week. This week, there are both shutdown and restart devices for caustic soda, and the supply is expected to increase [2] - The number of loss-making alumina enterprises increased, but there are currently no large-scale production reduction plans, and the short-term caustic soda demand is not expected to shrink significantly. In the fourth quarter, there are both expectations of new alumina capacity being put into production and cost-driven production reduction of existing devices [2] - If the alumina production reduction is implemented in the future, the impact will be greater than the replenishment demand of new devices. The caustic soda warehouse receipts have declined from a high level, and the pressure has eased. In the short term, SH2601 is expected to oscillate, with a daily range of around 2300 - 2420 [2]

Report Summary 1) Report Industry Investment Rating - Not provided in the given content 2) Core Viewpoints - The Shandong spot market pressure has been alleviated, and with alumina new capacity starting caustic soda tenders, the market may experience a short - term rebound. The cost support is strong due to the increase in Shandong grid electricity prices in October, so caustic soda should not be shorted aggressively [2] - The overall trend strength of caustic soda is neutral, with a trend strength value of 0 [3] 3) Summary by Relevant Catalogs [Fundamental Tracking] - On October 15, the Shandong liquid caustic soda market was partially stable. Some areas with low inventory and good sales supported price increases. The non - aluminum pick - up in the eastern market improved, and the inventory decreased; the southern inventory was not high, and sales were okay, leading to price hikes [1] - The 01 contract futures price was 2438, the cheapest deliverable 32% caustic soda spot price in Shandong was 800, the Shandong 32% caustic soda spot price converted to the futures price was 2500, and the basis was 62 [1] [Market Condition Analysis] - In October, there were new maintenance plans in Shandong and Hebei, so the supply pressure of caustic soda was not large. On the demand side, alumina plants in Hebei made concentrated purchases, and Shandong was expected to reduce inventory next week, making the local spot market strong in the short term [2] - The alumina industry has a pattern of high production and high inventory, with continuously compressed profits. Marginal production capacity supply may be affected by profits in the future. Although there is a demand for 560 million tons of new capacity in Guangxi from the end of this year to early next year, the low - profit situation may cause other alumina plants to reduce their inventory levels [2] [Trend Intensity] - The trend intensity of caustic soda is 0, indicating a neutral view, with the value ranging from - 2 (most bearish) to 2 (most bullish) [3]

Group 1: Report Industry Investment Rating - There is no information about the report industry investment rating in the provided content. Group 2: Report's Core View - The caustic soda market is currently under weak real - world pressure, but cost support is strong, and the market may show wide - range fluctuations [3]. - The current caustic soda futures are affected by the spot pressure of Shandong 32% caustic soda, and there are intertwined long - and short - term expectations that cannot be falsified in the short term [3]. Group 3: Summary by Related Catalogs 1. Fundamental Tracking - On September 29, 2025, the 01 - contract futures price was 2528, the cheapest deliverable spot 32% caustic soda price in Shandong was 780, the Shandong spot 32% caustic soda converted to the futures price was 2438, and the basis was - 91 [1]. 2. Spot News - On September 26, the local liquid caustic soda in Shandong remained stable. With the approaching of the long holiday, most enterprises were eager to reduce inventory, and the short - term market was still weak [2]. 3. Market Condition Analysis - The spot price of 32% caustic soda in Shandong is still under pressure, but the optimistic expectation brought by future alumina production cannot be falsified in the short term. The price of 50% caustic soda has risen due to regional arbitrage, and the inventory pressure of 50% caustic soda has been greatly relieved, limiting the further short - term decline of the spot price [3]. - The high - output and high - inventory pattern of alumina has compressed profits, and the marginal production capacity supply may be affected by profits in the future. Although there is a demand for 5.6 million tons of new capacity in Guangxi from the end of this year to the beginning of next year, the low - profit pattern may also lead to a decline in the inventory level of other alumina plants [3]. - Before the inventory - building starts, it is difficult to judge the gap caused by inventory - building, so the futures market is still trading the weak reality. The export situation has slightly improved compared with the previous period, and the Shandong - South China regional arbitrage also supports the 50% caustic soda market. The cost of caustic soda is strongly supported by the increase in Shandong's grid electricity price in October [3]. 4. Trend Intensity - The trend intensity of caustic soda is 0, indicating a neutral trend [5].

1. Report Industry Investment Ratings - No specific industry investment ratings are provided in the report. 2. Core Views of the Report 2.1烧碱 - The current situation of caustic soda is weak, but the future expectations are not pessimistic. The market may show wide - range fluctuations. The current upward pressure on caustic soda comes from exports and alumina. Although there is an optimistic expectation of alumina production in the future, the current situation of high inventory and low profit in the alumina industry restricts the rise of caustic soda prices. Before the start of alumina production and the improvement of exports, the upward driving force is insufficient [5]. 2.2 PVC - PVC is expected to show range - bound fluctuations. The high - production and high - inventory structure of PVC is difficult to change in the medium - term. The export market is under policy interference, and the growth rate may slow down. Although there are some short - term positive factors, the overall trend still faces pressure [7]. 3. Summary by Relevant Catalogs 3.1 Viewpoint Overview 3.1.1 Caustic Soda - Supply: The average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons or more is 81.9%, a week - on - week decrease of 1.5%. There are production cuts and shutdowns in Northwest, Central, East, and North China [5]. - Demand: In the alumina sector, high production and high inventory will continue to compress profits. Although the current production willingness is high, there is a problem of regional supply - demand mismatch. Non - aluminum demand has increased month - on - month, and there will be a phased peak - season restocking in the "Golden September and Silver October" period. Exports have improved recently, but the price difference between 50% and 32% caustic soda is still weak [5]. - Viewpoint: The spot price of caustic soda in Shandong is under pressure, but the optimistic expectation of alumina production in the future cannot be falsified in the short term. The futures market is in a game between reality and expectation, showing wide - range fluctuations [5]. - Valuation: The marginal device cost in Shandong is calculated to be 2,188 yuan/ton [5]. - Strategy: For single - side trading, pay attention to downstream restocking in mid - to late September and pre - production restocking of alumina after October. Do not participate in inter - period and inter - variety trading [5]. 3.1.2 PVC - Supply: The high - production structure of PVC is difficult to change in the short term. The maintenance volume is lower than that in 2023, and there will be more new capacity put into production in the future, especially in September, which will bring greater supply pressure [7]. - Demand: The competition pressure in the PVC export market has increased in 2025. Exports will still be affected by India's anti - dumping duties and BIS certification, and the growth rate of export demand may slow down in the second half of the year. Domestic demand related to the real estate industry is still weak, and enterprises' willingness to restock is low [7]. - Viewpoint: The PVC market is expected to show range - bound fluctuations. The high - production and high - inventory structure is difficult to change, and exports are subject to policy interference, so the medium - term trend still faces pressure [7]. - Valuation: The basis is weak, the month - to - month spread is weak, and the number of warehouse receipts continues to rise. The valuation is moderately high [7]. - Strategy: For single - side trading, the 01 contract has an upper pressure range of 5,000 - 5,150 yuan/ton and a lower support range of 4,800 - 4,850 yuan/ton. Do not participate in inter - period and inter - variety trading [7]. 3.2 Caustic Soda Price and Spread - Price: The price of the cheapest deliverable 32% caustic soda in Shandong is about 2,500 yuan/ton. The basis of caustic soda 01 is weakening, and the 11 - 1 spread is also weakening [12][14]. - Spread: In 2025, caustic soda exports are expected to increase by at least 30% year - on - year, with annual exports possibly exceeding 4 million tons. The export market still has support, and the export profit has expanded. The regional arbitrage space between Shandong and Guangdong has increased, and the price difference between flake and liquid caustic soda is at a high level. However, the price difference between 50% and 32% caustic soda is lower than the evaporation cost, which is negative for caustic soda [16][23][31]. 3.3 Caustic Soda Supply - Market Structure: Production is declining, and inventory is rising. The average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons or more is 81.9%, a week - on - week decrease of 1.5%. The factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons or more nationwide is 378,300 tons (wet tons), a week - on - week increase of 6.02% and a year - on - year increase of 18.22% [35][36][37]. - Planned Maintenance: Pay attention to the maintenance in Shandong and Hebei in October. Many enterprises have maintenance plans, which will affect the supply of caustic soda [41]. - Capacity Expansion: In 2025, the actual capacity expansion of caustic soda will be weaker than expected, with a capacity increase of about 2 - 3%. Although there are still many new capacities planned to be put into production, considering the continuous losses in chlorine - consuming downstream industries, especially PVC, the overall production may be lower than expected [42][45]. - Profit: The weak price of liquid chlorine has led to a decline in the overall profit of caustic soda. The decline in electricity prices has a significant impact on the cost of caustic soda [46][49]. 3.4 Caustic Soda Demand - Alumina: The alumina industry is operating at a high capacity, but inventory is rising, and profits are declining. At the end of the year, the production of new alumina plants will drive up the rigid demand and inventory of caustic soda, especially the tank - filling demand before production, which will lead to a significant increase in the short - term inventory demand for caustic soda [75][81]. - Pulp: The pulp industry is experiencing continuous capacity expansion, and demand is gradually shifting to the peak season. The operating rate of the finished paper industry has increased month - on - month [83][89]. - Other Industries: The operating rate of viscose staple fiber has increased, the printing and dyeing industry has recovered, and the short - term demand has increased month - on - month. The water treatment industry has stable operations, and the output of the ternary precursor industry has increased [94][96][98]. 3.5 PVC Price and Spread - The basis of PVC fluctuates, and the 1 - 5 spread is weakly fluctuating [105]. 3.6 PVC Supply and Demand - Supply: The operating rate of PVC production enterprises has decreased month - on - month. There are still seasonal maintenance plans in September - October 2025. There will be 2.2 million tons of new PVC capacity put into production in 2025, with more concentrated production in the second half of the year [110][114][115]. - Profit: The integrated plants in the Northwest have acceptable profits. The chlor - alkali industry chain's long - term trend of using caustic soda to subsidize chlorine makes it difficult for PVC to significantly reduce production due to losses [117][119]. - Inventory: PVC production enterprises are reducing inventory, while social inventory is increasing [121]. - Demand: The terminal demand in the real estate industry has not significantly recovered, but the overall operating rate of PVC downstream industries has increased month - on - month [126][132]. - Export: The export expectation of PVC has weakened. Although the cumulative exports from January to July increased year - on - year, the future export may be affected by India's anti - dumping policy [138][141]. - Warehouse Receipts: The number of PVC warehouse receipts continues to rise [142].

Report Industry Investment Rating - The report gives a short - term weak rating for caustic soda [1] Report's Core View - Currently, caustic soda has insufficient upward drivers, the futures market is reflecting the decline in spot prices in Shandong, and there is still pressure on spot prices in the short term. The main obstacles to the rise of caustic soda come from exports and alumina. Overall, the market is short - term weak [3] Summary by Related Catalogs Fundamental Tracking - The futures price of the 01 contract is 2560, the price of the cheapest deliverable 32% caustic soda spot in Shandong is 850, the spot 32% caustic soda in Shandong converted to the futures price is 2656, and the basis is 96 [1] Spot News - Taking Shandong as the benchmark, the liquid caustic soda in the province is generally stable today. There is resistance to high non - aluminum prices, and some negotiated orders have declined. Attention should be paid to the delivery volume of major downstream industries and the inventory changes of caustic soda plants [2] Market Condition Analysis - The lack of upward drivers for caustic soda mainly comes from exports and alumina. In terms of exports, new production capacity of Vinythai and high supply in Japan and South Korea lead to sufficient supply in Southeast Asia, the export profit cannot expand, the export orders are not improved, and the price difference between 50% and 32% caustic soda is weak. In terms of alumina, the high - output and high - inventory pattern compresses profits, and the supply of marginal production capacity may be affected by profits in the future. Although there are expected new production capacities in Guangxi at the end of this year and from Orient Hope at the beginning of next year, before the stockpiling starts, the market is difficult to achieve resonance between futures and spot [3] Trend Intensity - The trend intensity of caustic soda is - 1, indicating a weak trend [4]

Report Summary 1) Report Industry Investment Rating - The investment rating for the caustic soda industry is "Bullish with caution on near - month warehouse receipts" [1] 2) Core View of the Report - The caustic soda market's core driver is the continuous expansion of demand. With rising alumina demand and strong export support, the market is expected to have upward - driven spot prices during the downstream peak season. However, the weakness of chlorine - consuming downstream industries may limit profit expansion and cause potential passive production cuts. Overall, a bullish view is maintained, but near - month warehouse receipts need attention in the short term [1] 3) Summary by Relevant Content Fundamental Tracking - The futures price of the 11 - contract is 2700, the price of the cheapest deliverable 32% caustic soda in Shandong is 850, the Shandong spot 32% caustic soda converted to the futures price is 2656, and the basis is - 44 [1] Spot News - Based on Shandong, supported by a 20 yuan/ton increase in the procurement price of major downstream, local caustic soda plants raised prices to varying degrees. With low inventory pressure, the short - term market is expected to remain at a high level [1] Market Condition Analysis - Demand side: Alumina's rigid and stocking demand is rising, especially with 3.6 million tons of alumina production capacity expected to be put into operation in Guangxi by the end of this year, leading to tight local supply and increased demand for 50% caustic soda. The 93 - parade affects transportation, and a Shandong alumina plant may raise its procurement price. Export support remains strong, but inventory - building rhythms affect domestic prices [1] - Supply side: The weakness of chlorine - consuming downstream industries like PVC limits profit expansion and may cause passive production cuts in the future [1] Trend Intensity - The trend intensity of caustic soda is 1, indicating a moderately bullish view [2]
