策略报告：油价上升封住了PVC最大利空，联合利润改善才能解救烧碱目前脆弱的供给-20260309

1. Report Industry Investment Rating There is no information provided in the text about the report industry investment rating. 2. Core Viewpoints - The rising oil price has blocked the biggest negative factor for PVC, and only the improvement of combined profits can rescue the current fragile supply of caustic soda [1] - It is recommended to buy on dips, add long positions on significant pullbacks, and use put options to protect positions when the price rises too fast. Caustic soda may continue to rise, and the increase in liquid chlorine price means a decrease in electrolytic salt [9] - It is expected that there will be almost no growth in PVC production capacity in 2026, and the global PVC production cut expectation is continuously heating up [9] - The geopolitical conflict in the Middle East has caused the oil price to rise, the cost of the ethylene method has suddenly increased, and even led to losses, blocking its downward space; there is an expectation of spring maintenance for the calcium carbide method from March to April [9] - The downstream pipe and profile industries'开工 is seasonally recovering, and India is in the peak demand season at this time [9] - PVC enterprise inventory is seasonally decreasing [9] 3. Summary by Directory 3.1 Strategy and Risk Points - Recommended Strategy: Buy on dips, add long positions on significant pullbacks, and use put options to protect positions when the price rises too fast. Caustic soda may continue to rise, and the increase in liquid chlorine price means a decrease in electrolytic salt [9] - Previous Operating Logic: PVC social inventory is at a high level and continues to rise, and enterprise inventory increases seasonally. After the Spring Festival, the calcium carbide price has fallen, and the export order performance after the Spring Festival is average [9] - Reasons for Inflection Point/Trend Continuation Judgment: It is expected that there will be almost no growth in production capacity in 2026, and the global PVC production cut expectation is continuously heating up. The geopolitical conflict in the Middle East has caused the oil price to rise, the cost of the ethylene method has suddenly increased, and even led to losses, blocking its downward space; there is an expectation of spring maintenance for the calcium carbide method from March to April. The downstream pipe and profile industries'开工 is seasonally recovering, and India is in the peak demand season at this time. PVC enterprise inventory is seasonally decreasing [9] 3.2 Chart Tracking - PVC Price: The PVC price is at a low level and has risen rapidly recently. The PVC US dollar price has been rising continuously. The PVC 5 - 9 spread is -86 (up 52 within the week) [13][17][19] - Raw Material Price: Ethylene has risen sharply but is still at a low level. The calcium carbide price has fallen by about 3% within the week, and calcium carbide has been in long - term losses. The Shandong liquid chlorine price has quickly turned from negative to positive. The vinyl chloride Far East CFR price has risen by 4% within the week, and the Northeast Asian ethylene price has risen by 20% within the week [22][23][25] - PVC Production Capacity: There will be almost no new PVC production capacity in China in 2026 [31] - PVC Operating Rate: The calcium carbide method operating rate is expected to undergo spring maintenance, and the ethylene method operating rate is expected to be restricted by raw materials and has a large expected decline [35] - Demand: Pay close attention to the situation of export plates. The pipe and profile industries'开工 is seasonally recovering [37][38] - PVC Inventory: PVC operating rate has a downward expectation, and even the ethylene method supply is tight. The downstream operating rate is seasonally recovering, and inventory may be accelerated to be depleted [46] - Profit: The profit of the calcium carbide method has improved, while the profit of the ethylene method has suddenly turned into a loss. For the ethylene method, ethylene cracking may reduce the load, the circulation volume of imported ethylene cargoes has decreased, leading to an increase in the prices of ethylene and VCM, and then a significant increase in the cost of the ethylene method. For the calcium carbide method, it is also necessary to observe whether the semi - coke price will soar [47][48]
