  1. Report Industry Investment Rating No relevant content provided. 2. Core Views of the Report - PVC is in a phase of oscillatory decline, and the later price center is expected to decline. The supply - demand of PVC continues the extremely weak trend, with high - level production supply, weak domestic and export demand, and continuous accumulation of social inventory, which has now reached a level close to that of the same period last year [3]. - For traders, terminal customers, and production enterprises with inventory, it is recommended to short - hedge futures based on the weak reality. For those who need to purchase PVC, it is recommended to purchase as needed, and to buy out - of - the - money call options to prevent price increases [3]. 3. Summary by Related Catalogs 3.1 Fundamental Supply - Demand Situation Supply - In August, the overall PVC production showed an increasing trend. Although maintenance caused a certain reduction in supply, the release of new production capacity of 500,000 tons led to an overall increase in production [6]. - In 2025, the first - quarter production capacity of 300,000 tons was put into operation. Fujian Wanhua's 600,000 - ton capacity was included in production on August 2. It is expected that the annual production capacity growth rate will be 6.37%, and the pressure of production capacity release remains high [8]. - In August, PVC start - up first increased and then decreased, mainly related to its maintenance plan. There were fewer maintenance plans in the first ten - day period, with the start - up reaching around 79 - 80. In the middle and late ten - day periods, maintenance increased, and the start - up dropped to around 72 - 38 [8]. Demand - The current downstream start - up is at a low level compared to the same period, especially the start - up of pipe enterprises has deteriorated significantly. Domestic downstream product enterprises continue to purchase at low prices and resist high - priced raw materials. Production is weak in the high - temperature summer season [9]. - This week, the sample of PVC production enterprises decreased by 2.17% month - on - month and increased by 9.13% year - on - year. As of August 17, the final anti - dumping duty decision on PVC in India is waiting for the announcement of the Indian Ministry of Finance, estimated to be announced and implemented in about 20 - 30 days. The prices in the Chinese mainland have generally increased by 46 - 62 US dollars/ton, while those in Japan, South Korea, the United States, and Chinese Taipei have decreased. In the short term, there is a certain rush - to - export performance. Pay attention to the implementation time of the Indian anti - dumping duty, which will have a negative impact on China's exports if implemented [9]. Inventory - As of August 28, the original sample inventory in East China was 445,400 tons, an increase of 3.44% from the previous period and a decrease of 3.91% year - on - year. The expanded sample inventory in East China was 766,600 tons, a month - on - month increase of 5.04% and a year - on - year decrease of 6.89%. The sample inventory in South China was 52,500 tons, an increase of 1.74% from the previous period and an increase of 44.23% year - on - year. The total original sample warehouse inventory in East and South China was 497,900 tons, an increase of 3.26% from the previous period and a year - on - year decrease of 0.4%. The total expanded sample warehouse inventory in East and South China was 819,000 tons, a month - on - month increase of 4.83% and a year - on - year decrease of 4.72% [182]. Raw Materials - Lancoke: In August, the Lancoke price rose slightly twice. The price of medium - sized Lancoke in Shaanxi increased from 606 yuan/ton at the beginning of the month to 645 yuan/ton, a 6.6% increase. The start - up rate of Lancoke increased from 53.65% at the beginning of the month to 56.7%. In the future, with the end of some enterprise maintenance and the weakening of coal prices, the start - up of Lancoke enterprises is expected to further increase [68]. - Calcium carbide: In August, the calcium carbide market price showed a flat "V" - shaped trend, with the end - of - month price rising compared to the beginning. The average start - up load rate of the calcium carbide industry decreased in the first ten - day period, then rebounded and stabilized. In the future, most calcium carbide start - ups may remain stable, but the increase in start - up may be limited [73]. - Caustic soda: In August, the price center of liquid caustic soda moved up. The 32% liquid caustic soda in Shandong increased from 820 yuan/ton at the beginning of the month to 870 yuan/ton, a 6.1% increase. The start - up of caustic soda decreased from 83.9% at the beginning of the month to 82.4%. In the future, it is expected that the short - term liquid caustic soda price will remain strong, and the caustic soda profit will continue to make up for the comprehensive chlor - alkali profit [78]. 3.2 Monthly Price Data Changes - Futures prices: V2601 decreased from 5,176 yuan/ton at the end of July to 4,907 yuan/ton on August 29, a decrease of 269 yuan/ton; AS60E decreased from 5,469 yuan/ton to 5,200 yuan/ton, a decrease of 269 yuan/ton [14]. - PVC spot prices: The calcium - carbide method prices in East, South, North, and Northwest China all decreased to varying degrees; the ethylene - method price in East China decreased from 5,100 yuan/ton to 5,000 yuan/ton, a decrease of 100 yuan/ton [14]. - Prices of related products in the PVC industry chain: The prices of Lancoke, ethylene, and 32% ion - membrane caustic soda in Shandong increased, while the prices of calcium carbide in Shandong and 32% ion - membrane caustic soda in Inner Mongolia decreased [14]. - Spreads: The V2601 - 2605 spread remained unchanged at - 293 yuan/ton; the 01 basis increased from - 355 yuan/ton to - 280 yuan/ton, an increase of 75 yuan/ton [14]. - Profits: The comprehensive profit of calcium - carbide method (northwest integrated chlor - alkali) decreased from 590.91 yuan/ton to 376.61 yuan/ton; the comprehensive profit of calcium - carbide method (north - China purchased calcium carbide) decreased from 169 yuan/ton to 19.35 yuan/ton; the profit of ethylene - method (east - China purchased VCM) increased from 5.20 yuan/ton to 27.38 yuan/ton [14]. 3.3 Disk Review and Disk Data - This month's market review: In August, the PVC price first oscillated and then weakened under the increasing supply - demand pressure.
