山东下游采购价连续下调，烧碱延续弱势

1. Report Industry Investment Ratings - For caustic soda: Cautious short - selling hedging [3] - For PVC: Neutral [7] 2. Core Views of the Report - Caustic Soda: The price of caustic soda in Shandong has been continuously decreasing, and the market remains weak. Although the plant - level inventory has decreased, it is still at a high level. The futures are deeply in contango, and the spot price is falling. In the short term, it follows the basis repair logic, and there is still room for compression of chlor - alkali comprehensive profit in the later stage [1][2][3]. - PVC: The price of PVC has increased due to the rise in the price of upstream raw material ethylene driven by the Middle East geopolitical conflict. However, the supply - demand fundamentals have not significantly improved. The supply pressure is large, and the domestic demand is weak. Although the export is increasing in the short term, there are uncertainties in the Indian import anti - dumping policy [6][7]. 3. Summary According to the Directory I. Caustic Soda Price & Spread - As of June 20, 2025, the SH main contract closing price of caustic soda futures was 2,256 yuan/ton (-32), the basis of 32% liquid caustic soda in Shandong was 275 yuan/ton (-31). The spot price of 32% liquid caustic soda in Shandong was 810 yuan/ton (-20), and that of 50% liquid caustic soda was 1,330 yuan/ton (-50) [1]. II. PVC Price & Spread - As of June 20, 2025, the main contract closing price of PVC futures was 4,903 yuan/ton (+3), the East China basis was - 113 yuan/ton (+17), and the South China basis was - 23 yuan/ton (+27). The spot price of calcium carbide - based PVC in East China was 4,790 yuan/ton (+20), in South China was 4,880 yuan/ton (+30). The spot price of ethylene - based PVC in East China was 5,000 yuan/ton (+50), and in South China was 4,920 yuan/ton (+0) [5]. III. Cost - Profit - Caustic Soda: As of June 20, 2025, the comprehensive profit of chlor - alkali in Shandong (1 ton of caustic soda + 0.8 tons of liquid chlorine) was 837.83 yuan/ton (-62.50), the comprehensive profit of chlor - alkali in Shandong (1 ton of caustic soda + 1 ton of PVC) was 205.03 yuan/ton (-62.50), the single - variety profit of caustic soda in Shandong was 1,540.15 yuan/ton (-62.50), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of caustic soda + 1 ton of PVC) was 1,284.03 yuan/ton (+0.00) [2]. - PVC: As of June 20, 2025, the production gross profit of calcium carbide - based PVC was - 493.98 yuan/ton (+17.77), the production gross profit of ethylene - based PVC was - 640.42 yuan/ton (-79.88), and the export profit of PVC was - 10 US dollars/ton (-1) [5]. IV. Caustic Soda Supply - The caustic soda operating rate was 81.20% (+0.30%), and the weekly output was 79.28 tons (+0.23). Recently, there are both plant overhauls and restarts in Shandong, and the overall operating rate has increased slightly month - on - month. In the later stage, there are plans to put into production new capacities in Gansu Yaowang and Tianjin Bohua, and the supply - side pressure is expected to increase [1][2]. V. Liquid Chlorine Price and Liquid Chlorine Downstream - As of June 20, 2025, the price of liquid chlorine in Shandong was 1 yuan/ton (+0). The operating rates of downstream products such as propylene oxide, epichlorohydrin, and dichloromethane have increased, and the weekly output of chloroform has also increased [2]. VI. PVC Supply - The upstream calcium carbide average operating load was 63.10% (+1.51%), the PVC operating rate was 78.62% (-0.63%), the calcium carbide - based PVC operating rate was 80.43% (-1.34%), and the ethylene - based PVC operating rate was 73.81% (+1.22). The loss due to shutdown and overhaul was 12.57 tons (+0.37). Although the overall operating rate has decreased month - on - month, the output is still at a high level, and there are plans to put into production new capacities from June to July, so the supply pressure is still large [5][6]. VII. Caustic Soda Downstream Demand - The operating rate of the main downstream product, alumina, was 80.74% (-0.13%), the weekly output was 171.50 tons (-0.30), and the port inventory was 6.80 tons (+1.80). The operating rates of non - aluminum downstream industries such as printing and dyeing, viscose staple fiber, white cardboard, and broad - leaf pulp have shown different degrees of decline or increase [1]. VIII. PVC Downstream Demand - The comprehensive operating rate of PVC downstream was 44.31% (-1.49%), among which the operating rates of PVC pipes, profiles, and films have all decreased. The pre - sales volume of production enterprises was 64.79 tons (+0.96). The domestic demand is weak, but the export orders have increased month - on - month, and the Indian BIS standard policy has been postponed, which supports the short - term export demand [5][6]. IX. Caustic Soda & PVC Inventory Data - Caustic Soda: The domestic liquid caustic soda plant - level inventory was 36.65 tons (-3.88), and the flake caustic soda plant - level inventory was 2.85 tons (+0.00) [2]. - PVC: The PVC plant - level inventory was 40.16 tons (+0.51), and the social inventory was 35.51 tons (+0.03), including 31.23 tons in East China (+0.01) and 4.28 tons in South China (+0.02) [5].
