中泰期货烧碱周报：液氯价格未能如预期下跌，烧碱期货价格承压下行-20250928

Report Industry Investment Rating - Not provided in the content Core Viewpoints - This week, the caustic soda futures showed a significant downward trend, with short - sellers actively increasing positions to push down the futures price, and there were stop - loss phenomena among long - sellers. The main reasons include weak spot prices, the non - decline of liquid chlorine prices contrary to expectations, and the continuous decline of alumina spot and futures prices. In the later stage, the caustic soda futures may be supported by the liquid chlorine price, especially during the National Day holiday. Therefore, the caustic soda futures should be treated with a volatile mindset [5]. Summary by Directory 01 Overview - Supply: In the period from September 19 - 25, 2025, the average capacity utilization rate of Chinese caustic soda sample enterprises with a capacity of 200,000 tons and above was 82.5%, a 0.6% week - on - week increase. Northwest had new device production cuts and maintenance, while North China and East China had increased loads after device maintenance. Next week, except for the Southwest region, other six regions are expected to increase their loads, with an estimated capacity utilization rate of about 85.9% and a weekly output of about 845,700 tons [5]. - Demand - Alumina: China's alumina production was 1.855 million tons, a decline from last week's 1.861 million tons. Shandong's alumina production remained flat at 626,000 tons. The liquid caustic soda purchase price of large - scale alumina factories in Shandong dropped to 740 yuan/ton, with a 100% converted price of 2,313 yuan/ton. Alumina prices and production profits declined recently [5]. - Demand - Viscose Staple Fiber: China's viscose staple fiber production was 90,000 tons, a 30 - ton increase from last week.

Most dyeing factories planned to have a 2 - 3 - day holiday during the National Day [5]. - Export: In August, the export volume of liquid caustic soda was 213,500 tons, and the export volume of flake caustic soda was 66,800 tons [5]. - Inventory: As of September 25, 2025, the factory inventory of fixed liquid caustic soda sample enterprises with a capacity of 200,000 tons and above in China was 391,200 tons (wet tons), a 3.4% week - on - week increase and a 26.26% year - on - year increase. The storage capacity ratio of domestic liquid caustic soda sample enterprises was 20.78%, a 0.64% week - on - week increase [5]. - Profit: This Friday, the average price of Shandong liquid caustic soda was 2,500 yuan/ton, the average price of liquid chlorine was - 100 yuan/ton, and the chlor - alkali profit was 306 yuan/ton, at a historically low level. The decline in liquid caustic soda prices compressed the comprehensive chlor - alkali profit [5]. - Strategy: Adopt a volatile mindset for single - side trading; no strategy for arbitrage and options [5]. 02 Price - The report presents price trends of Shandong chlor - alkali spot, flake caustic soda, export caustic soda, caustic soda futures, basis, inter - month spreads, raw salt, and coal, with data sources from Mysteel and compiled by Zhongtai Futures [7][10][13][16] 03 Supply - Caustic Soda Supply: Data on China's weekly caustic soda production, caustic soda startup rate, caustic soda device loss volume, and cumulative caustic soda production are provided, with data sources from Mysteel and compiled by Zhongtai Futures [20][21] - Caustic Soda Inventory and Chlor - Alkali Profit: Information on the liquid caustic soda inventory of Chinese sample enterprises, caustic soda futures warehouse receipts, and Shandong chlor - alkali enterprise profits is presented, with data sources from Mysteel and compiled by Zhongtai Futures [23][24] - Chlor - Alkali Device Maintenance Plan: This week, many chlor - alkali devices have resumed operation after maintenance, and there are also some devices under maintenance.
