纯苯苯乙烯日报：苯乙烯港口库存压力持续-20251030

Report Industry Investment Rating - No investment rating provided in the report Core Viewpoints - For pure benzene, port inventory has slightly declined, but low downstream开工 rates of styrene, CPL, and adipic acid have dragged down demand, leading to a continuously weak port basis. Domestic pure benzene开工 has also decreased, and the impact of previous sanctions on some refinery loads can be resolved by switching crude oil resources [3] - For styrene, despite short - term maintenance, port inventory has not been reduced, and there is still pressure. New device startups such as Jihua and Guangxi Petrochemical have had an impact. Downstream开工 has changed little, but提货 is average, and the finished product inventory pressure of the three major hard rubbers is still high, so the port inventory pressure of EB persists [3] Summary by Directory I. Pure Benzene and EB's Basis Structure, Inter - period Spread - The report mentions figures related to the basis of pure benzene and EB, including the basis of pure benzene futures contracts, the spread between pure benzene spot and M2 paper goods, and the spread between consecutive contracts of pure benzene and EB [8][11][16] II. Pure Benzene and Styrene Production Profits, Internal and External Spreads - Information on production profits and internal - external spreads of pure benzene and styrene is provided, such as styrene non - integrated device production profit, pure benzene FOB US Gulf - FOB South Korea spread, and import profits of pure benzene and styrene [19][22][30] III. Pure Benzene and Styrene Inventory,开工 Rate - Pure benzene port inventory is 8.50 million tons (- 1.40 million tons), and its开工 rate has declined. Styrene port inventory is still under pressure, with East China port inventory at 193,000 tons (- 9,500 tons), and its开工 rate is 69.3% (- 2.6%) [1][3][34] IV. Styrene Downstream开工 and Production Profits - EPS production profit is 255 yuan/ton (- 5 yuan/ton), with an开工 rate of 61.98% (- 0.54%); PS production profit is - 45 yuan/ton (- 5 yuan/ton), with an开工 rate of 53.80% (+ 0.00%); ABS production profit is - 192 yuan/ton (+ 48 yuan/ton), with an开工 rate of 72.80% (- 0.30%) [2] V. Pure Benzene Downstream开工 and Production Profits - For pure benzene downstream products, caprolactam production profit is - 1850 yuan/ton (+ 35), with an开工 rate of 88.89% (- 3.52%); phenol - acetone production profit is - 329 yuan/ton (+ 0), with an开工 rate of 78.00% (+ 0.00%); aniline production profit is 1050 yuan/ton (+ 224), with an开工 rate of 76.48% (+ 0.75%); adipic acid production profit is - 1165 yuan/ton (- 23), with an开工 rate of 55.80% (- 3.30%) [1] Strategy - Unilateral: None - Basis and inter - period: None - Cross - variety: Short - term, go long on the spread of pure benzene processing fees (pure benzene - naphtha) [4]
