Report Summary 1. Report Industry Investment Rating - Not provided in the given content 2. Core Viewpoints - V2509 fell 1.31% to close at 4,970 yuan/ton. The PVC supply may show an upward trend as the operating load gradually increases after the new production capacity is put into operation in August. The domestic downstream demand is in the off - season with only rigid procurement. The anti - dumping policy release is delayed, but the rainy season still hinders overseas demand. The domestic calcium carbide supply and demand tend to be loose this week, and the price may fall; the ethylene US dollar market has sufficient supply, and the price may remain stable. Currently, the V2509 contract has a small premium, and it is expected to fluctuate slightly in the range of 4,900 - 5,100 yuan/ton in the short term. For V2601, pay attention to the support around 5,040 yuan/ton and the resistance around 5,300 yuan/ton [3]. 3.

1. Report Industry Investment Rating - No information provided 2. Core Viewpoints of the Report - V2509 fell 1.17% to close at 4,981 yuan/ton. The supply side saw some PVC device overhauls and restarts last week, with the capacity utilization rate increasing by 0.05% to 76.84%. The demand side had low - level and narrow - range improvement in the start - up of the main downstream pipes, a continued decline in the start - up of profiles, and other varieties' start - up rates remaining at a low level. The PVC social inventory increased by 5.67% to 72.21 million tons last week. After the new capacity is put into operation in August, the supply is likely to rise. The impact of restarted devices will expand this week, and the capacity utilization rate is expected to increase month - on - month. Domestic downstream demand is in the off - season, with only rigid demand for purchases. The delay of the Indian BIS certification and anti - dumping policy has not effectively promoted overseas demand due to the rainy season. The calcium carbide industry's losses are dragging down the start - up, and its price is expected to be supported; the ethylene market's supply - demand changes are limited, and its price is expected to remain stable. Currently, the futures price has a slight premium over the spot price. V2509 is expected to fluctuate weakly, and attention should be paid to the support around 4,900 yuan/ton technically [3] 3.

Core Viewpoints of the Report - PVC faces high supply and inventory pressure with weak domestic demand, lacking positive fundamental support and under pressure [3][4] - Caustic soda's overall supply - demand fundamentals are expected to be weak, with insufficient upward price drivers [3][4] 3. Summary by Related Catalogs Market News and Important Data PVC - Futures price and basis: PVC main contract closed at 4758 yuan/ton (-35); East China basis -98 yuan/ton (-5); South China basis -8 yuan/ton (+35) [1] - Spot price: East China calcium carbide method quoted at 4660 yuan/ton (-40); South China calcium carbide method quoted at 4750 yuan/ton (+0) [1] - Upstream production profit: PVC calcium carbide method gross profit -621 yuan/ton (+37); PVC ethylene method gross profit -516 yuan/ton (+10); PVC export profit 13.8 dollars/ton (+6.1) [1] - Inventory and开工: PVC factory inventory 38.7 tons (-1.9); PVC social inventory 37.8 tons (-2.0); PVC calcium carbide method operating rate 73.19% (-2.33%); PVC ethylene method operating rate 72.90% (+2.84%); PVC operating rate 73.11% (-0.90%) [1] - Downstream orders: Production enterprise pre - sales volume 60.3 tons (-2.9) [1] Caustic Soda - Futures price and basis: SH main contract closed at 2456 yuan/ton (+7); Shandong 32% liquid caustic soda basis 294 yuan/ton (-7) [1] - Spot price: Shandong 32% liquid caustic soda quoted at 880 yuan/ton (+0); Shandong 50% liquid caustic soda quoted at 1420 yuan/ton (+0) [1] - Upstream production profit: Shandong caustic soda single - product profit 1759 yuan/ton (+0); Shandong chlor - alkali comprehensive profit (0.8 tons of liquid chlorine) 935.8 yuan/ton (+0.0); Shandong chlor - alkali comprehensive profit (1 ton of PVC) 313.78 yuan/ton (-50.00); Northwest chlor - alkali comprehensive profit (1 ton of PVC) 1425.55 yuan/ton (+20.20) [2] - Inventory and开工: Liquid caustic soda factory inventory 40.09 tons (-1.50); Flake caustic soda factory inventory 2.95 tons (+0.03); Caustic soda operating rate 84.10% (+1.50%) [2] - Downstream开工: Alumina operating rate 78.10% (+1.43%); Printing and dyeing East China operating rate 63.23% (+0.00%); Viscose staple fiber operating rate 80.30% (-0.35%) [2] Market Analysis PVC - Supply side: New maintenance scale is small, previous maintenance devices continue to stop, PVC operating rate declines slightly month - on - month, but there are few planned maintenance in the later period, and PVC production is at a high level in the same period. With the expected new capacity put into production from June to July, supply pressure is still high [3] - Demand side: PVC downstream product enterprises' operating rate is at a low level in the same period, PVC pipes, profiles and films' operating rate is weakly stable, downstream market mainly purchases on - demand at low prices, and the spot price center of PVC is weakly volatile. Demand is weak [3] - Cost side: The upstream raw material calcium carbide market is weakly stable, and the cost - side support for PVC is insufficient [3] Caustic Soda - Supply side: Some new maintenance enterprises are added, and previous maintenance enterprises resume production one after another. The overall operating rate of caustic soda rises slightly month - on - month, but manufacturers' loads mostly run at a high level supported by profits. With the expected new capacity of caustic soda put into production from June to July, supply pressure is still high [3] - Demand side: The spot price of alumina, the main downstream product, continues to rise, and the production profit of the alumina industry is significantly repaired. The reduction of production may weaken, and the expectation of some capacity resumption is strong, which may support the caustic soda market price in the short term. Non - aluminum downstream terminal purchases are cautious, mainly replenishing on - demand, and the operating rate of non - aluminum terminals such as viscose staple fiber and printing and dyeing is still at a low level in the same period, and non - aluminum demand remains weak [3] Strategy - PVC: Cautiously bearish. High inventory and supply pressure continue, domestic demand is weak, and the price is expected to run weakly at the bottom in the short term [4] - Caustic Soda: Neutral. The overall supply - demand fundamentals are expected to be weak, and the price may continue to fluctuate weakly. Attention should be paid to downstream replenishment continuity and alumina capacity resumption progress [4]

Report Industry Investment Rating - The report does not provide an industry investment rating. Core View of the Report - PVC will experience short - term fluctuations and face pressure in the later stage. Although there are some positive factors such as macro - level Sino - US phased reconciliation and short - term terminal product export rush, the high - production and high - inventory structure is difficult to alleviate, and high - price transactions are slowing down [1][2]. Summary by Relevant Catalog Fundamental Tracking - As of the report, the 09 - contract futures price of PVC is 5041, the East China spot price is 4880, the basis is - 161, and the 9 - 1 month spread is - 103. The domestic PVC spot price has been raised this week. Due to positive macro expectations, rising industrial products, and improved export inquiries and deliveries of products, the price has increased. However, high - price transaction sentiment has weakened, and market sentiment is more watchful. Currently, the ex - warehouse spot price of calcium carbide - based type 5 PVC in East China is 4800 - 4950 yuan/ton, and the ethylene - based price has stabilized at 4900 - 5100 yuan/ton [1]. Market Condition Analysis - **Positive factors**: At the macro - level, Sino - US phased reconciliation is sentimentally positive, and short - term terminal product export rush supports the market [2]. - **Negative factors**: From a fundamental perspective, Northwest chlor - alkali integration still has profits, and the high - production and high - inventory structure of PVC is difficult to alleviate. The high - production pattern is difficult to change in the short term because the maintenance volume in the first quarter of PVC was low, and high - profit caustic soda demand in 2025 supports the chlor - alkali industry to offset losses in PVC. Moreover, there will be more new capacity put into production, especially in June. The high - inventory pressure persists, and export demand can only relieve it temporarily. In 2025, the PVC export market faces greater competition pressure, affected by India's anti - dumping duties and BIS certification. Domestic demand for PVC downstream products related to real estate is still weak year - on - year, and enterprises have low inventory - building willingness [2]. Trend Intensity - The trend intensity of PVC is 0, indicating a neutral trend. The trend intensity ranges from - 2 (most bearish) to 2 (most bullish) [3][4].
