Group 1: Investment Ratings - No investment ratings for the industry are provided in the report. Group 2: Core Views Caustic Soda - Recent downstream alumina prices are stable, but market trading enthusiasm has declined. The domestic electrolytic aluminum industry has high profits, increasing restocking demand. Supply is expected to increase as there will be fewer maintenance enterprises in the future than in July. In August, the number of warehouse receipts in the main production areas is expected to increase. The demand side lacks obvious positive support, and downstream customers are sensitive to price changes. The overall outlook is neutral to weak, and attention should be paid to the purchasing situation of alumina enterprises [2]. PVC - New production capacities are being put into operation, domestic trade is weak, spot trading is sluggish this week, and the number of warehouse receipts on the futures market has increased. Inventory pressure continues to rise, and demand is difficult to improve. New production capacities at home and abroad will continue to be released in August. The overall supply - demand pressure remains high, but attention should be paid to the impact of coking coal prices on PVC prices [3]. Futures and Options Strategies - For both caustic soda and PVC, the futures strategy is to short on rallies, and the options strategy is to buy put options [4][5]. Group 3: Summary of Each Section Caustic Soda Price and Market Dynamics - The caustic soda futures price has shown various trends under different market conditions, such as falling due to factors like increased supply and weakening demand from alumina plants, and rising due to positive policies and increased demand from major downstream industries [8]. Supply - As of Thursday this week, the weighted average operating load rate of sample enterprises in major regions across the country was 89.10%, an increase of 1.48 percentage points from last week. The inventory of 32% liquid caustic soda in expanded sample enterprises in East China and Shandong has increased [27]. Alumina Impact - From the end of 2024 to 2025, the planned production capacity of alumina is 1230 million tons (including 200 million tons of replacement), with an estimated annual production capacity growth rate of around 10%. The estimated annual output of alumina in 2025 is over 88 million tons, with a production growth rate of around 6%. The new alumina production capacity will increase the demand for caustic soda by around 800,000 tons per year, with a relatively concentrated increase of 150,000 tons from April to June [32]. Other Factors - The price of bauxite is stable, and port inventories have slightly declined this week. The electrolytic aluminum industry has high production but low出库 volume and high in - plant inventories. Non - aluminum downstream industries are fragmented, and attention should be paid to their resistance to high caustic soda prices. The estimated export profit of caustic soda is strengthening [40][46][51][58]. PVC Price and Market Dynamics - The PVC futures price has fluctuated under different market conditions, such as falling due to weak supply - demand and poor macro - atmosphere, and rising due to policy expectations and improved market sentiment [65]. Profit - The industry profit of PVC has weakened on a month - on - month basis [71]. Supply - This week, the capacity utilization rate of PVC production enterprises was 79.46%, a month - on - month increase of 2.62% and a year - on - year increase of 4.73%. The capacity utilization rates of both the calcium carbide method and the ethylene method have increased [87]. Demand - The two major downstream industries of PVC, profiles and pipes, face great pressure, and the demand from the real estate sector is still negative. The domestic demand has not improved significantly, and downstream orders are significantly lower than the average of the past five years [97]. Inventory - PVC inventories have continued to rise on a month - on - month basis, and the pressure is prominent [105]. International Market - The international price of PVC has shown narrow fluctuations. In June 2025, PVC exports decreased on a month - on - month basis but increased on a year - on - year basis. The import volume increased on a month - on - month and year - on - year basis. The export window to Southeast Asia and India has opened, but weekly export transactions are weak [112][123].
