Daily Market Summary - Fundamentals - Price: On August 25, the styrene main contract closed down 0.65% at 7,330 yuan/ton with a basis of 25 (+28 yuan/ton); the pure benzene main contract closed down 0.03% at 6,206 yuan/ton [2]. - Cost: On August 25, Brent crude closed at 63.7 (+0.1 dollars/barrel), WTI crude at 67.7 dollars/barrel, and East China pure benzene spot was 6,072.5 yuan/ton (-17.5 yuan/ton) [2]. - Inventory: Styrene sample factory inventory was 20.3 tons (-0.3 tons), a 1.1% de - stocking; Jiangsu port inventory was 16.2 tons (+1.3 tons), an 8.5% stocking. Pure benzene port inventory was 14.4 tons (-0.2 tons), a 1.1% de - stocking [2]. - Supply: Styrene may have reduced supply due to plant maintenance at the end of August. Currently, the weekly styrene output is 37.1 tons (+0.2 tons) with a plant capacity utilization of 78.5% (+0.3%) [2]. - Demand: The downstream 3S开工率 varies. EPS capacity utilization is 61.0% (+2.9%), ABS 71.1% (+0%), and PS 57.5% (+1.1%), showing a continuous increase [2]. - Views - Pure Benzene: In the short - term, it maintains resilience due to plant fluctuations and low inventory, but after September, supply - demand contradictions may intensify, and prices may decline [3]. - Styrene: It has a short - term strong and medium - term pressured pattern. Short - term price increase is limited, and the medium - term is in an oversupply situation [4]. II.
