1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - SH2509 oscillated weakly and closed at 2,512 yuan/ton. The supply - side saw new device maintenance in Central and East China last week, with a slight change in caustic soda capacity utilization rate to 80.4%. The demand - side showed an increase in alumina and viscose staple fiber开工率, while a decrease in printing and dyeing开工率. The inventory of liquid caustic soda factories decreased last week. In July, the planned maintenance capacity of caustic soda decreased, but the caustic soda start - up rate was restricted due to the backlog of liquid chlorine. This week, with frequent stop - and - restart of devices, the capacity utilization rate is expected to rise slightly. Affected by losses, the delivery volume of Shandong alkali plants to alumina enterprises decreased. Non - aluminum off - season demand is weak, and downstream purchases are mainly for rigid needs. In the short term, low profits and limited downstream demand are the core contradictions. Recently, the non - aluminum purchasing enthusiasm has increased, and the spot price may remain firm. For futures, pay attention to the pressure around 2,600 yuan/ton for SH2509 [1] 3.

This week, the capacity utilization rate is expected to rise slightly. Affected by losses, the delivery volume of Shandong alkali plants to alumina enterprises decreased. Non - aluminum off - season demand is weak, and downstream purchases are mainly for rigid needs. Recently, non - aluminum purchasing enthusiasm has increased, and the spot price may remain firm [1]

1. Report Industry Investment Rating - No information provided 2. Core View of the Report - The current core contradiction is the low profit and limited downstream demand. In the short - term, the spot price may remain firm due to the increased non - aluminum procurement enthusiasm, and for the futures, attention should be paid to the pressure around 2600 for SH2509 [1] 3. Summary by Relevant Catalogs 3.1 Futures Market - The main contract closing price of caustic soda is 2532 yuan/ton, the futures trading volume is 874144 hands with an increase of 283841 hands, and the futures open interest is 237978 hands with a decrease of 14539 hands.

As of July 10th, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above nationwide was 374,300 tons (wet tons), a decrease of 2.58% compared with the previous week and an increase of 2.64% compared with the same period last year [1] 3.7 Supply and Demand Analysis - On the supply side, new plants in Central and East China were under maintenance last week, while the load of some plants in South and North China increased, and the capacity utilization rate of caustic soda decreased by 0.1% to 80.4%. On the demand side, the alumina operating rate increased by 1.72% to 83.28%, with an average profit of 300.3 yuan/ton; the viscose staple fiber operating rate increased by 2.63% to 77.80%, and the printing and dyeing operating rate decreased by 1.29% to 59.9% [1] 3.8 Inventory Situation - Last week, the liquid caustic soda factory inventory decreased by 2.58% to 374,300 tons, with little inventory pressure [1] 3.9 Outlook - The planned maintenance capacity of caustic soda in July has decreased, but due to the concentrated maintenance of PVC downstream of liquid chlorine, the backlog of liquid chlorine has led to a deep price inversion and dragged down the chlor - alkali profit, thus restricting the increase in the caustic soda operating rate. This week, there are many plant shutdowns and restarts, and the capacity utilization rate is expected to increase slightly. Affected by losses, the delivery volume of Shandong alkali plants to alumina enterprises has decreased. The non - aluminum demand is weak in the off - season, and downstream enterprises mainly purchase based on rigid demand [1]

Report Summary 1. Report Industry Investment Rating No investment rating is provided in the report. 2. Core Viewpoints - In the short - term, SH2509 is expected to fluctuate within a range. Technically, attention should be paid to the support around 2340 and the resistance around 2400. The rebound sustainability of the 09 contract is questionable due to the lack of fundamental positives, but the downside space of the futures price is limited as it is close to the cost below 2200. In the long - term, the supply pressure in the caustic soda industry will increase as there are many caustic soda production units scheduled to be put into operation from June to July, and the caustic soda spot market still faces significant pressure with limited demand [2][3]. 3.

1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - SH2509 is expected to show a volatile trend in the short - term, with the range estimated around 2220 - 2320. Supply pressure is high in the medium - to - long - term, and there is still room for the caustic soda spot price to decline, while the futures price is undervalued below 2200 but lacks positive drivers for a rebound [1]. 3. Summary by Relevant Catalogs 3.1 Futures Market - The main contract closing price of caustic soda is 2272 yuan/ton. The futures open interest is 293,284 lots, a decrease of 4,497 lots. The net position of the top 20 futures is 15,116 lots, a decrease of 23,262 lots. The futures trading volume is 508,464 lots, a decrease of 145,252 lots. The closing price of the January contract is 2266 yuan/ton, and the closing price of the May contract is 2329 yuan/ton [1]. 3.2 Spot Market - The price of 32% ion - membrane caustic soda in Shandong is 780 yuan/ton, a decrease of 30 yuan/ton; in Jiangsu, it is 930 yuan/ton, a decrease of 20 yuan/ton. The converted - to - 100% price of 32% caustic soda in Shandong is 2438 yuan/ton, a decrease of 93 yuan/ton. The basis of caustic soda is 166 yuan/ton, a decrease of 109 yuan/ton [1]. 3.3 Upstream Situation - The mainstream price of raw salt in Shandong is 210 yuan/ton, unchanged; in the Northwest, it is 220 yuan/ton, unchanged. The price of steam coal is 635 yuan/ton, unchanged [1]. 3.4 Industry Situation - The mainstream price of liquid chlorine in Shandong is - 25 yuan/ton, unchanged; in Jiangsu, it is - 50 yuan/ton, unchanged [1]. 3.5 Downstream Situation - The spot price of viscose staple fiber is 13,080 yuan/ton, unchanged. The spot price of alumina is 3140 yuan/ton, a decrease of 10 yuan/ton. From June 13th to 19th, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 81.2%, a week - on - week increase of 0.3%. As of June 19th, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above nationwide was 366,500 tons (wet tons), a week - on - week decrease of 9.57% and a year - on - year decrease of 5.63% [1]. 3.6 Market Analysis - The SH2509 contract rose 0.31% to close at 2272 yuan/ton. On the supply side, the caustic soda capacity utilization rate increased by 0.3% to 81.2% last week, with little change from the previous period. On the demand side, alumina is still in the resumption stage; for non - aluminum sectors, the operating rate of viscose staple fiber increased by 0.24% week - on - week to 80.80%, and the operating rate of printing and dyeing decreased by 0.64% week - on - week to 60.73%. In terms of inventory, the liquid caustic soda factory inventory decreased by 5.63% week - on - week to 365,600 tons, at a moderately high level during the same period. This week, Dongying Huatai's 750,000 - ton device is under maintenance, and some devices are planned to restart, so the capacity utilization rate may decline. There are many caustic soda production devices to be put into operation from June to July, resulting in high medium - to - long - term supply pressure. The delivery volume of the main contract remains high; the non - aluminum off - season has weak rigid demand and resistance to high prices. In terms of cost, the downstream demand for steam coal has improved recently, but the price increase lacks a sustainable driving force, and the power cost support of self - supplied power plants is limited. The profit of chlor - alkali is acceptable, and there is still room for the caustic soda spot price to decline; the futures price is at a discount, and the valuation is low below 2200, but there is a lack of positive drivers for a rebound [1].

1. Report Industry Investment Rating - No relevant content provided 2. Core Viewpoints of the Report - The alumina industry's profit has recovered, with an increasing number of restarted production facilities, which is expected to boost the demand for caustic soda. However, some non - aluminum industries have entered the off - season, with cautious purchasing and mainly for rigid demand. Industry maintenance and alumina stockpiling support the spot price, but the commissioning of new caustic soda plants from June to July and the uncertainty of downstream stockpiling demand bring an expectation of weakening supply - demand in the future. The price of near - month contracts is stronger than that of far - month contracts. The current main contract is at a low level with a high basis, so short - selling is not advisable [3]. 3.

Report Summary 1) Report Industry Investment Rating No investment rating information is provided in the report. 2) Core Viewpoints - The short - term SH2509 is expected to show a volatile trend, with support around 2410 and resistance around 2500 [3]. - The alumina industry's profit has recovered, but the current scale of resumption of production is not obvious. Some non - aluminum industries are in the off - season, and the non - aluminum downstream demand is mainly for rigid needs, with limited caustic soda consumption [3]. - The profit of the chlor - alkali industry is considerable, which drives the increase in supply. The capacity utilization rate is expected to increase this week, but the large amount of maintenance capacity in June may partially relieve the supply pressure [3]. 3) Summary by Directory Futures Market - The main contract closing price of caustic soda is 2456 yuan/ton, with a daily increase of 7 yuan/ton; the futures trading volume is 341,091 lots, with a decrease of 146,848 lots; the futures position is 198,892 lots, with an increase of 1239 lots; the net position of the top 20 futures is - 13,473 lots, with an increase of 7506 lots [3]. - The closing price of the January contract is 2363 yuan/ton, a decrease of 31 yuan/ton; the closing price of the May contract is 2408 yuan/ton, a decrease of 33 yuan/ton [3].

There will be more maintenance capacity in June, which may partially relieve the supply pressure [3]. - The liquid caustic soda factory inventory decreased by 3.59% week - on - week to 400,900 tons, which is at a relatively high level in the same period [3]. - In the short term, SH2509 is expected to fluctuate, with support around 2410 and resistance around 2500 [3].

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - The SH2509 contract of caustic soda is expected to show a volatile trend in the short term, with support around 2410 and resistance around 2520 [3]. - The profit of the chlor - alkali industry is considerable, driving an increase in supply. Some plants in North and East China plan to increase production this week, and the capacity utilization rate is expected to rise month - on - month [3]. - The profit of the alumina industry has recovered, but the scale of resumption of production is not yet obvious. The supply contraction of Guinea ore restricts the increase in the alumina开工率 and increases the unit consumption of caustic soda, which has no obvious positive or negative impact on caustic soda in the short term [3]. - Some non - aluminum industries are entering the off - season, with limited caustic soda consumption demand, and non - aluminum downstream demand is mainly based on rigid needs [3]. 3.
