1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - The fundamentals of synthetic rubber are supportive, and it operates within the valuation range. The short - term market is slightly bullish, while the medium - term remains within the fundamental valuation range [2][4]. - The price of butadiene is expected to be volatile in the short term with support at the bottom. In the long term, supply pressure is the main contradiction, and it is expected to enter a weak pattern after the macro - sentiment eases [5]. 3. Summary by Related Catalogs 3.1 Synthetic Rubber Weekly Viewpoint 3.1.1 Supply - The output of high - cis butadiene rubber this week was 27,300 tons, a decrease of 1,400 tons compared to last week, a 5.93% month - on - month decrease, with a capacity utilization rate of 68.17%, a 4.29 - percentage - point month - on - month decline. Some plants such as Qixiang Tengda and Maoming Petrochemical carried out short - term maintenance. Next week, the plants of Shandong Yihua and Qixiang Tengda are expected to restart, and the output is expected to increase [4]. 3.1.2 Demand - In terms of rigid demand, the capacity utilization rate of semi - steel tires slightly decreased, while that of all - steel tires slightly increased. Next week, the capacity utilization rate of tire sample enterprises will vary. The capacity utilization rate of semi - steel tires may continue to decline slightly, while that of all - steel tires is expected to increase. In terms of substitution demand, the price difference between NR - BR main contracts is maintained at 700 - 900 yuan/ton, and the substitution demand remains high. Therefore, the overall demand for butadiene rubber maintains a high year - on - year growth rate [4]. 3.1.3 Inventory - As of August 6, 2025 (Week 32), the inventory of high - cis butadiene rubber sample enterprises in China was 31,400 tons, an increase of 100 tons compared to the previous period, a 0.38% month - on - month increase. Although some production plants carried out short - term maintenance this week, the downstream was waiting for price drops, and the price of arbitrage resources was relatively low, resulting in slow spot transactions. The inventory of sample production enterprises increased, while that of sample trading enterprises decreased slightly [4]. 3.1.4 Valuation and Viewpoint - In the short term, it is slightly bullish, and in the medium term, it operates within the fundamental valuation range. The current static valuation range of butadiene rubber futures is 11,200 - 11,700 yuan/ton, and the dynamic valuation is expected to rise slightly. The upper limit of the fundamental valuation is 11,600 - 11,700 yuan/ton, and the lower limit is 11,200 yuan/ton [4]. 3.1.5 Strategy - Unilateral: Bullish with upper pressure at 11,700 - 11,800 yuan/ton and lower support at 11,100 - 11,200 yuan/ton. - Inter - period: No relevant strategy. - Inter - variety: The price difference between NR - BR is expected to narrow in the short term [4]. 3.2 Butadiene Weekly Viewpoint 3.2.1 Supply - Some enterprises carried out plant maintenance this week, and the domestic butadiene supply decreased. The output was 102,500 tons, a decrease of 900 tons compared to the previous period, a 0.87% decline, with a capacity utilization rate of 69.76%, a 0.21% month - on - month decline [5]. 3.2.2 Demand - In the synthetic rubber sector, the operating rates of butadiene rubber and styrene - butadiene rubber remained high, and the demand for butadiene maintained a high year - on - year level. With the resumption of butadiene rubber plants, the rigid demand for butadiene is expected to increase. In the ABS sector, due to high inventory pressure, the demand for butadiene is expected to remain constant. In the SBS sector, the operating rate increased slightly, and the demand for butadiene remained stable [5]. 3.2.3 Inventory - From July 31 to August 6, 2025, the total inventory of domestic butadiene samples increased by 8.71% compared to last week. The inventory of sample enterprises decreased slightly by 1.50%, while the inventory of sample ports increased by 41.35% due to the arrival of imported vessels. As of August 6, the inventory at East China ports was about 14,700 tons, an increase of 4,300 tons compared to the previous period [5]. 3.2.4 Viewpoint - The price is expected to be volatile in the short term with support at the bottom. The overall arrival volume of butadiene is expected to be low, and the port price may remain resilient. In the long term, supply pressure is the main contradiction, and it is expected to enter a weak pattern after the macro - sentiment eases [5]. 3.3 Butadiene Fundamentals - Butadiene is currently in the stage of supply - demand pricing, with a low correlation with the raw material end [8]. - To match the expansion of downstream industries such as ABS, SBS, styrene - butadiene, and butadiene rubber, butadiene production capacity is continuously expanding, and the expansion speed and amplitude are slightly faster than those of downstream industries [10]. 3.4 Synthetic Rubber Fundamentals 3.4.1 Supply of Butadiene Rubber - Output: The output and operating rate data of butadiene rubber are presented, and the operating status and future plans of various enterprises' plants are detailed [34][35]. - Cost and profit: The daily theoretical production cost, profit, and gross profit margin data of butadiene rubber are provided [37][38][39]. - Import and export: The monthly import and export volume data of butadiene rubber are presented [41][42]. - Inventory: The weekly inventory data of butadiene rubber enterprises, traders, and futures are provided [46][48]. 3.4.2 Demand of Butadiene Rubber - Tire: The inventory and operating rate data of semi - steel and all - steel tires in Shandong Province are presented [50][51].
