纯苯、苯乙烯日报：纯苯供需双增叠加油价反弹，苯乙烯弱势反弹待考-20250822

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Views of the Report - The pure benzene market maintains a pattern of increasing supply and demand. The supply is driven by the stable operation of refineries and the recovery of hydrobenzene plants, while the demand shows a mixed performance. Overall, the short - term fundamentals have marginally improved, but the contradiction between high latent inventory and insufficient terminal demand remains [3]. - The styrene market rebounded with the cost in the short - term. However, the medium - term trend depends on the implementation of maintenance and the recovery of terminal demand. The supply is currently high, and the demand improvement is limited, but the situation may marginally ease in September [4]. Group 3: Summary of Each Section 1. Daily Market Summary (1) Fundamentals - Price: On August 21, the styrene main contract closed up 0.05% at 7289 yuan/ton with a basis of 26 (+36 yuan/ton), and the pure benzene main contract closed down 0.08% at 6200 yuan/ton [2]. - Cost: On August 21, Brent crude closed at 62.7 (+0.9 dollars/barrel), WTI at 66.8 (+1.1 dollars/barrel), and the spot price of East China pure benzene was 6110 yuan/ton (+5 yuan/ton) [2]. - Inventory: Styrene sample factory inventory was 20.3 tons (-0.3 tons, -1.1% MoM), Jiangsu port inventory was 16.2 tons (+1.3 tons, +8.5% MoM), and pure benzene port inventory was 14.4 tons (-0.2 tons, -1.1% MoM) [2]. - Supply: Styrene production may decrease in late August due to plant maintenance. Currently, the weekly output is 37.1 tons (+0.2 tons), and the plant capacity utilization rate is 78.5% (+0.3%) [2]. - Demand: The capacity utilization rates of downstream 3S vary. EPS is 61.0% (+2.9%), ABS is 71.1% (+0%), and PS is 57.5% (+1.1%), showing a continuous increase [2]. (2) Views - Pure benzene: The supply is relatively stable with some increase, and the demand shows a mixed trend. The cost is supported by the short - term oil price rebound, but the long - term oil price may face pressure. Overall, the short - term fundamentals improve, but problems remain [3]. - Styrene: It rebounded with the cost in the short - term. The supply is high, and the demand improvement is limited. In September, the supply may contract due to maintenance, and the demand may enter the peak season, which may ease the supply - demand contradiction [4]. 2. Industry Chain Data Monitoring - Price: The prices of styrene and pure benzene futures and spot, as well as related spreads, are presented, showing different trends of increase and decrease. For example, the styrene futures main contract increased by 0.05%, and the pure benzene futures main contract decreased by 0.08% [6]. - Output and Inventory: The output of styrene and pure benzene in China increased slightly, and the inventory situation varied. Styrene port inventory increased, while factory inventory and pure benzene port inventory decreased [7]. - Capacity Utilization Rate: The capacity utilization rates of styrene and its downstream products, as well as pure benzene downstream products, changed. Some increased, such as EPS and PS, while others decreased, such as aniline and caprolactam [8]. 3. Industry News - China's shale cracking raw material supply affects the cost of naphtha, and the import volume is expected to reach a record high in 2025 [9]. - The global diesel shortage supports refinery profits, having a structural impact on the crude oil and chemical chains [9]. - India plans to accelerate the expansion of petrochemical production to cope with China's leading position in the global petrochemical market [9]. 4. Industry Chain Data Charts - The report provides multiple charts showing the historical data of pure benzene and styrene prices, spreads, inventory, and capacity utilization rates, with data sources from iFinD and Steel Union data [14][21]
