氯碱日报：山东液碱库存增加，关注下游采购节奏-20250828

Report Industry Investment Rating - Not provided in the content Core Viewpoints - PVC is affected by the sentiment of the black sector and follows a downward trend. In the short - term, attention should be paid to the impacts from the macro and cost sides. The supply pressure is large in the long - term, and the demand remains weak. The cost of coal and ethylene is strengthening, and its impact on PVC cost needs to be continuously monitored [4]. - The spot price of caustic soda is mainly stable. The supply is affected by maintenance, and the demand is expected to increase. Attention should be paid to the restocking rhythm during the peak season and the production start - up rhythm of alumina in Guangxi [4]. Summary by Relevant Catalogs Market News and Important Data PVC - Futures price and basis: The closing price of the PVC main contract is 4949 yuan/ton (-50), the East China basis is -249 yuan/ton (+10), and the South China basis is -149 yuan/ton (+10) [2]. - Spot price: The East China calcium carbide - based PVC is quoted at 4700 yuan/ton (-40), and the South China calcium carbide - based PVC is quoted at 4800 yuan/ton (-40) [2]. - Upstream production profit: The price of semi - coke is 630 yuan/ton (+0), the price of calcium carbide is 2730 yuan/ton (+0), the calcium carbide profit is -64 yuan/ton (+0), the gross profit of PVC calcium carbide - based production is -223 yuan/ton (+8), the gross profit of PVC ethylene - based production is -592 yuan/ton (-52), and the PVC export profit is 16.4 US dollars/ton (+5.2) [2]. - Inventory and production start - up: The in - factory inventory of PVC is 30.6 tons (-2.1), the social inventory is 50.8 tons (+1.5), the production start - up rate of PVC calcium carbide method is 76.07% (-3.14%), the production start - up rate of PVC ethylene method is 72.44% (-5.48%), and the overall production start - up rate of PVC is 75.02% (-3.82%) [2]. - Downstream order situation: The pre - sales volume of production enterprises is 72.5 tons (-6.6) [2]. Caustic Soda - Futures price and basis: The closing price of the SH main contract is 2699 yuan/ton (-4), and the basis of 32% liquid caustic soda in Shandong is 20 yuan/ton (+35) [2]. - Spot price: The price of 32% liquid caustic soda in Shandong is 870 yuan/ton (+10), and the price of 50% liquid caustic soda in Shandong is 1350 yuan/ton (+0) [2]. - Upstream production profit: The single - variety profit of caustic soda in Shandong is 1728 yuan/ton (+31), the comprehensive profit of chlor - alkali in Shandong (0.8 tons of liquid chlorine) is 744.5 yuan/ton (+31.3), the comprehensive profit of chlor - alkali in Shandong (1 ton of PVC) is 682.53 yuan/ton (+1.25), and the comprehensive profit of chlor - alkali in the Northwest (1 ton of PVC) is 1458.45 yuan/ton (+70.71) [3]. - Inventory and production start - up: The factory inventory of liquid caustic soda is 39.64 tons (-4.14), the factory inventory of flake caustic soda is 2.36 tons (+0.03), and the production start - up rate of caustic soda is 83.20% (-0.90%) [3]. - Downstream production start - up: The production start - up rate of alumina is 85.78% (+0.14%), the production start - up rate of printing and dyeing in East China is 63.86% (+2.40%), and the production start - up rate of viscose staple fiber is 86.22% (+0.18%) [3]. Market Analysis PVC - Supply side: Maintenance increases, and the production start - up rate decreases month - on - month. However, the overall production start - up is at a high level under the support of chlor - alkali profits. With the gradual mass production of new production capacity, the long - term supply pressure is still large [4]. - Demand side: The production start - up of downstream products remains at a low level, and enterprises maintain just - in - time procurement. The export signing and delivery volume increase week - on - week. Affected by the rush to export before the implementation of anti - dumping duties, the PVC export in July exceeded expectations. After India announced an increase in anti - dumping duties, the rush to export is expected to continue, and the export expectation in the fourth quarter weakens [4]. - Inventory: The social inventory continues to accumulate and is relatively high year - on - year. The 09 contract has a large warehouse receipt pressure [4]. - Cost: The prices of coal and ethylene have strengthened recently, and their impact on the PVC cost needs to be continuously monitored [4]. Caustic Soda - Supply side: The maintenance of chlor - alkali enterprises increases, and the production start - up rate decreases month - on - month, but it is still at a high level in the same period. The production start - up in Shandong increases slightly, also at a high level in the same period. After the maintenance of Yantai Wanhua, the production start - up may decline slightly [4]. - Demand side: The profit of alumina is good, and the production start - up is stable month - on - month. The delivery volume of caustic soda to alumina plants, the main downstream, gradually increases, and the spot price remains stable. The non - aluminum downstream production start - up increases slightly month - on - month, and the procurement is acceptable. Affected by the military parade in late August, the transportation of caustic soda is restricted, and the factory inventory may accumulate later. With the approaching of the peak season expectation, the pending orders in Shandong are acceptable [4]. - Cost and profit: The price of liquid chlorine is weak, but there is still cost support. The chlor - alkali profit is at a medium level in the same period [4]. Strategy PVC - Single - side: Wait and see [5][6] - Inter - period: Wait and see; for SH10 - 01, consider a long - spread strategy when the price difference is low [5][6] - Inter - variety: No strategy [5][6]
