1. Report Industry Investment Rating - Not provided in the given content 2. Core Views of the Report - For caustic soda, mid - to long - term, alumina profit is worrying due to over - expansion, demand for caustic soda is insufficient, and new production capacity is being launched, so the supply - demand outlook is weak. In the short term, the supply side is in the concentrated maintenance stage, pre - holiday alumina demand has improved, and the spot price has increased, with the futures price also strengthening after the holiday. [2] - For PVC, the supply - demand surplus is prominent, domestic demand is weak due to the weak real - estate chain, exports are supported in the first quarter but mostly through price cuts. After the "Golden March and Silver April" period, the terminal demand will be weak during the rainy season. The BIS extension to June may lead to an early export boom, and if it is finally implemented, it will have a negative impact on PVC. [3] 3. Summaries According to Relevant Catalogs Caustic Soda - Market Situation: Macro turned weak, caustic soda operation rate was higher year - on - year, and the liquid caustic soda plant inventory stopped decreasing weekly. The August contract repaired the basis, and the futures price dropped rapidly. The spot market was in a game, and there were concerns about the supply return and weakening demand. [6] - Profit: The current integrated profit of caustic soda is at a normal level in the same period. [12] - Supply: Maintenance is gradually concentrated, the operation rate is decreasing, and caustic soda plants are seasonally destocking. As of May 8, the national average operation rate was 87.47%, up 1.14% from last week, while the Shandong region's operation rate was 89.24%, down 0.99% from the previous week. [17][23] - Demand from Alumina: From the end of 2024 to 2025, the planned alumina production capacity to be put into operation is 12.3 million tons (2 million tons of replacement), with an estimated annual production capacity growth rate of around 10%. The estimated annual alumina output in 2025 is over 88 million tons, with a production growth rate of around 6%. The new alumina demand is equivalent to 400,000 - 550,000 tons of caustic soda per year, and the total demand increment for caustic soda is around 800,000 tons, with 150,000 tons of new demand concentrated from April to June. [28] - Alumina Profit and Operation Rate: Alumina profit has recently recovered but is still in the red. As of May 8, the SMM alumina industry profit was estimated at - 60 yuan/ton. The operation rate has been declining, and there is limited demand for caustic soda in the medium term. [35] - Aluminum Bauxite: The price has declined, which may further drive down the alumina price. [36] - Non - aluminum Downstream: The non - aluminum downstream industries are fragmented, and the impact of tariffs should be noted. [46] - Export: The theoretical export profit of caustic soda is at a low level. [53] Polyvinyl Chloride (PVC) - Market Situation: The 09 contract is mainly trading on expectations driven by real - estate, maintenance, and export expectations. The market sentiment was hot, but then the futures price declined due to weak supply - demand drivers and a poor commodity atmosphere. [60] - Profit: The overall industry profit of PVC is low. [66] - Supply: Seasonal maintenance is concentrated, and the operation rate continues to decline. In March 2025, PVC powder production was 2.04205 million tons, a month - on - month increase of 9.04% and a year - on - year increase of 0.77%. As of April 24, the overall operation rate was 75.67%. [82] - Downstream Demand: The two major downstream industries of PVC, profiles and pipes, face great pressure. The real - estate sector has a negative impact on demand. After the "Golden March and Silver April" period, the performance of hard products is average, and that of soft products is relatively better, but domestic demand has not improved significantly. [91] - Real - estate Data: The new construction area of real - estate is still weak, and attention should be paid to whether housing prices can stabilize effectively. [92] - Inventory: There was a small seasonal inventory increase during the May Day holiday, and the year - on - year inventory pressure is limited. [99] - External Market: The Asian PVC market price was stable weekly. The CFR China price was 700 US dollars/ton, Southeast Asia was 670 US dollars/ton, and CFR India was 700 US dollars/ton. [118] - Import and Export: The US tariff has an impact on the export of terminal products, especially floor coverings. The BIS extension to June may have a negative impact on PVC if it is finally implemented. [117][118]
