The start - up rate of alumina in Henan has increased significantly due to the end of maintenance and the commissioning of new devices [56][57] - **Non - Aluminum Demand**: The start - up of non - aluminum industries is stable but lower than the same period last year. It has entered the seasonal off - peak, and the start - up rate has begun to decline [66][67] - **Liquid Chlorine Downstream**: The start - up rate has rebounded [74] - **Maintenance Plan**: Multiple enterprises in different regions have maintenance plans in September and October, which will affect the supply of caustic soda [77]

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - SH2601 fluctuated slightly, closing at 2,576 yuan/ton. The caustic soda capacity utilization rate increased by 1.8% week-on-week to 84.2% last week. The alumina开工率 decreased by 1.2% week-on-week to 84.38%, the viscose staple fiber开工率 increased by 1.08% week-on-week to 87.10%, and the printing and dyeing开工率 increased by 0.9% week-on-week to 65.63%. The liquid caustic soda factory inventory increased by 2.17% week-on-week to 387,800 tons last week. One set of equipment in Central China and two sets in the Northwest are scheduled for maintenance this week, which may lead to a slight decline in capacity utilization. There are many maintenance plans for chlor-alkali plants in September, and the industry's supply pressure is expected to be relieved. Some alumina enterprises have short-term elastic production, but due to the considerable industry profits, the production enthusiasm of alumina enterprises is still high. Non-aluminum demand has a seasonal increase, and some previously shut-down plants have restarted. The inventory pressure of liquid caustic soda is not large, and attention should be paid to the subsequent inventory removal rhythm. In terms of spot, the price of liquid caustic soda in Shandong is expected to remain stable or rise slightly in the short term. In terms of futures, the high-level of caustic soda warehouse receipts has decreased, but the fourth-quarter production capacity expectation still suppresses the futures price, and the main contract may continue to be at a discount. Technically, SH2601 should pay attention to the support around 2,530 [1] 3.

Report Industry Investment Rating - The report does not provide an industry investment rating. Core Viewpoint - The caustic soda market is in a volatile situation. Near - term, the futures price has corrected due to near - month warehouse receipts and weak exports, but domestic demand is stable. The warehouse receipt issue is a short - term impact, and the quality of the peak season depends on export performance [1][3] Summary by Related Catalogs Fundamental Tracking - The 01 contract futures price is 2670, the cheapest deliverable spot 32 - alkali price in Shandong is 870, the Shandong spot 32 - alkali converted to the futures price is 2719, and the basis is 49 [1] Spot News - Taking Shandong as the benchmark, the liquid caustic soda price in Shandong remained stable today, with little price change. Attention should be paid to the delivery volume of major downstream industries [2] Market Condition Analysis - In the past week, the caustic soda futures price corrected, mainly due to near - month warehouse receipts (mostly from Zhejiang, posing high pressure on near - month long positions) and weak exports (sufficient supply in Southeast Asia, poor export signing, and weak 50 - alkali - 32 - alkali price difference). Domestic demand is stable, non - aluminum demand may improve in the peak season, alumina production is at a high level, and there is an expected new production capacity of 360 million tons in Guangxi at the end of this year, which may drive the circulation of domestic 50 - alkali [3] Trend Intensity - The trend intensity of caustic soda is 0, indicating a neutral view [5]

1. Report Industry Investment Rating - The report suggests not to chase short positions in caustic soda and take a bullish view in the fourth quarter, with a trend strength of 0, indicating a neutral stance [1][5] 2. Core Viewpoints - The recent correction in caustic soda futures prices is due to near - month warehouse receipts and weak exports, but the warehouse receipt issue is a short - term impact. The supply - demand contradiction in the second half of this year mainly comes from the concentrated stocking before the alumina production [3] - Domestic demand remains stable. Non - aluminum demand is expected to improve in the peak season, and alumina has high - level production with strong rigid demand. The later alumina stocking will drive the circulation of domestic 50% caustic soda, depending on the production start - up rhythm [3] 3. Summary by Relevant Catalogs 3.1 Fundamental Tracking - On August 28, 2025, the 01 contract futures price was 2699, the cheapest deliverable spot 32% caustic soda price in Shandong was 860, the Shandong spot 32% caustic soda converted to the futures price was 2688, and the basis was - 12 [1] 3.2 Spot News - Taking Shandong as the benchmark, the overall price of liquid caustic soda in Shandong remained stable today, with a small number of enterprises raising prices. The current short - term inventory of liquid caustic soda in the province is continuously low, and attention should be paid to the change in the delivery volume of major downstream industries [2] 3.3 Market Condition Analysis - The suppression factors for the rise of caustic soda are the 114 lots of warehouse receipts in the 09 contract as of August 26 (mainly from Zhejiang) and the weak export situation due to sufficient supply in Southeast Asia. The 50% - 32% caustic soda price spread is weak, resulting in insufficient driving force for the price increase [3] - Domestic demand is stable. Non - aluminum demand will improve in the peak season, and alumina production is at a high level. There are expectations of 3.6 million tons of new production capacity in Guangxi at the end of this year, and the alumina stocking will drive the circulation of domestic 50% caustic soda [3] 3.4 Trend Strength - The trend strength of caustic soda is 0, with a range of [-2, 2], indicating a neutral stance [5]

1. Report Industry Investment Rating - No information provided on the industry investment rating in the report. 2. Core Viewpoints of the Report - In the short - term, the caustic soda market is in a off - season, but the market is expected to enter the consumption peak season in September and October. The previous positive factors have not disappeared, and the market can refocus on these factors. - The short - selling orders should take profits at an appropriate time, and long - buying orders should enter the market at an appropriate time. The production profit of caustic soda will enter a seasonal expansion stage later [5]. 3. Summary by Directory 3.1 Overview - **Supply**: In the week of 20250801 - 0807, the average capacity utilization rate of China's caustic soda sample enterprises with a capacity of 200,000 tons and above was 85.1%, a week - on - week increase of 1.2%. The capacity utilization rate in the Northwest increased significantly, slightly increased in North China, and decreased in Northeast China. It is estimated that next week, the capacity utilization rate will be about 83.1%, and the weekly output will be about 804,500 tons [5]. - **Demand**: China's alumina production was 1851,000 tons this week, a slight increase from last week. The production of viscose staple fiber remained unchanged at 85,100 tons. As of August 7, 2025, the comprehensive operating rate in the Jiangsu - Zhejiang region was 59.28%, a week - on - week increase of 0.38%. The terminal market demand was still weak, and the orders for autumn and winter fabric samples were lower than in previous years. The industry generally expects demand to pick up gradually after mid - September [5]. - **Inventory**: As of August 7, 2025, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above was 461,700 tons (wet tons), a week - on - week increase of 8.84% and a year - on - year increase of 17.08%. The capacity utilization rate of liquid caustic soda sample enterprises was 26.56%, a week - on - week increase of 2.87% [5]. - **Profit**: Last Friday, the average price of liquid caustic soda in Shandong was 2,500 yuan/ton, and the average price of liquid chlorine was - 150 yuan/ton.

Report Industry Investment Rating - No information provided Core View of the Report - The recent rebound of caustic soda futures prices is driven by previous production cuts due to weak liquid chlorine and downstream seasonal restocking, but the supply - side drive is unsustainable as production - cut devices have resumed, and the demand is in the off - season, so the rebound lacks sustainability. Once costs decline and spot prices struggle to rise, the market may short caustic soda profits. The supply pressure is still high in July with reduced maintenance capacity compared to June and new capacity of 1.1 million tons from June to July. Non - aluminum demand support is weak, while the export direction provides some support [3] Summary by Relevant Catalogs Fundamental Tracking - The 09 - contract futures price is 2466, the cheapest deliverable spot 32 - alkali price in Shandong is 820, the Shandong spot 32 - alkali converted to the futures price is 2563, and the basis is 97 [1] Spot News - In the Shandong liquid caustic soda market, prices are stable, with local areas holding steady and observing. High - concentration caustic soda has low inventory supported by previous orders, but high - price sales are poor after the price increase. Low - concentration caustic soda's high - price sales have slowed down, and the inventory of each factory varies [2] Market Condition Analysis - The recent rebound of caustic soda futures prices is due to previous production cuts of some devices affected by weak liquid chlorine and downstream seasonal restocking. However, the rapid decline of liquid chlorine has led to the resumption of chlorine - consuming downstream industries, and the production - cut devices of caustic soda have basically recovered this week, so the supply - side drive is unsustainable. The demand is in the seasonal off - season, and downstream willingness to restock at high prices is low, so the rebound lacks sustainability. In July, the maintenance capacity of caustic soda has decreased significantly compared to June, with maintenance mainly concentrated in the Northwest and East China, and previously maintained devices in Shandong will gradually restart. From June to July, new caustic soda capacity may reach 1.1 million tons, so the supply pressure is still high. Non - aluminum demand support is weak, the alumina's caustic soda inventory is neutral, and the export direction provides some support with strong willingness to restock at low prices [3] Trend Intensity - The caustic soda trend intensity is - 1, indicating a weak bearish view [4]

Group 1: Report Industry Investment Rating - No information provided Group 2: Core Viewpoints of the Report - The recent rebound in caustic soda futures prices is due to some plants reducing production due to the weak liquid chlorine market and downstream seasonal restocking, but the supply - side driver is unsustainable as plants have resumed production, and the demand is in a seasonal off - season, so the rebound lacks sustainability [3] - In July, the caustic soda maintenance capacity decreased significantly compared to June, with maintenance concentrated in the Northwest and East China, and the previously shut - down plants in Shandong will restart. The new production capacity from June to July may reach 1.1 million tons, so the supply pressure is still high [3] - On the demand side, non - aluminum demand support is weak, the alumina caustic soda inventory is neutral, but the export direction provides good support with strong willingness to restock at low prices [3] - The caustic soda trend strength is 0, indicating a neutral outlook [3] Group 3: Summary by Relevant Catalogs Fundamental Tracking - On July 15, 2025, the 09 - contract futures price was 2532, the cheapest deliverable spot 32% caustic soda price in Shandong was 820, the Shandong spot 32% caustic soda converted to the futures price was 2563, and the basis was 31 [1] Spot News - On July 15, 2025, the price of liquid chlorine at Shandong Xinfa remained unchanged at - 250 yuan ex - factory [2] Market Condition Analysis - The recent rebound in caustic soda futures prices is driven by supply - side production cuts and downstream restocking, but the supply - side driver is short - lived as plants have resumed production, and the demand is in a seasonal off - season [3] - In July, maintenance capacity decreased, and new production capacity from June to July may reach 1.1 million tons, leading to high supply pressure [3] - Non - aluminum demand support is weak, alumina inventory is neutral, and the export market provides good support [3]

Report Summary 1. Report Industry Investment Rating - Not provided 2. Core View of the Report - After the May Day holiday, caustic soda futures may be short - term oscillating stronger based on the holiday spot price trend and the new capacity launch of alumina. However, considering the return of 05 warehouse receipts to the spot market and the weakness of the demand side, caustic soda is still in a negative feedback pattern [3][4] 3. Summary by Relevant Catalogs 3.1 Fundamental Tracking - On May 7, 2025, the 09 - contract futures price of caustic soda was 2498, the price of the cheapest deliverable 32% caustic soda in Shandong was 780, the Shandong spot 32% caustic soda converted to the futures price was 2438, and the basis was - 61 [1] 3.2 Spot News - Taking Shandong as the benchmark, the price of 32% ion - membrane caustic soda closed at 800 yuan/ton today, up 2.56% from the previous period. After the May Day holiday, most enterprises in Shandong had good sales, low inventory, and the price showed an upward trend. In the short term, attention should be paid to changes in enterprise inventory and delivery volume data, and there is a possibility of further price increases [2] 3.3 Market Condition Analysis - **Demand Side**: Alumina has low profit and high raw material caustic soda inventory. Although new capacity launch increases the rigid demand, the short - term inventory demand for caustic soda is weak. Non - aluminum demand is generally weak, and some industries such as viscose staple fiber, printing and dyeing, and pulp and paper industries are greatly affected by the trade war, with obvious declines in production. Exports can support caustic soda, but the purchasing of foreign merchants is cautious due to the trade war [3] - **Supply Side**: There will still be new maintenance in May. Since the profit is not in deficit, the manufacturer's load is generally at a high level. Attention should be paid to the impact of chlorine - consuming downstream on caustic soda supply. Although in the first quarter, the impact of chlorine - consuming downstream was limited due to the high profit of caustic soda, if caustic soda and liquid chlorine decline, marginal device supply will be affected by profit [3] 3.4 Trend Intensity - The trend intensity of caustic soda is 0, with the value range of [- 2, 2] for integers, indicating a neutral trend [4]

Market Overview - As of April 24, PVC social inventory decreased by 5.15% month-on-month to 687,700 tons, and decreased by 20.77% year-on-year [1] - On April 28, the PVC market in Hangzhou stabilized, with slight fluctuations in spot prices; new goods prices are relatively high, with various pricing ranges reported [1] Production and Demand - The overall PVC operating rate is at 78.6%, up 1.3% week-on-week; the calcium carbide method is at 78.6% (down 0.7%), while the ethylene method is at 78.6% (up 6.5%) [1] - The production volume for the week is 450,000 tons, remaining stable month-on-month, with seasonal demand expected to improve [2] Supply Chain Dynamics - The industry is currently in a destocking mode due to recent export deliveries and concentrated maintenance on the supply side [3] - There are plans for new installations to come online in May and June, which may exert supply pressure [3] Price Trends - The cost side is supported by declining calcium carbide prices, leading to a downward shift in futures prices; however, speculative demand at low prices is not expected to drive significant rebounds [2] - Current futures contract range is projected between 4,900 and 5,250 [2] Inventory and Profitability - PVC social and factory inventories have decreased by 6%, indicating a significant destocking trend [2] - The profitability of integrated caustic soda/PVC enterprises remains largely unchanged, with weak domestic demand impacting price stability [3]
