纯苯苯乙烯周报：苯乙烯检修量级仍可，但下旬投产继续释放-20251012

Report Industry Investment Rating No information provided. Core Viewpoints - The escalation of the Sino-US trade war has dragged down the entire chemical sector. For pure benzene, although the port inventory has decreased after the holiday and downstream提货 is okay, there are still doubts about the long - term procurement sustainability of some downstream products, and the concentrated maintenance of styrene in late October will drag down the demand. Overseas, the pressure of South Korean pure benzene being shipped to China has increased, and the driving force for continuous destocking is not strong. - For styrene, the port inventory has slightly accumulated again after the holiday, and the inventory pressure persists. The downstream提货 performance is still average. The supply side has some devices under maintenance, but there are also new device startups. Overseas demand is weak, and the import pressure from Europe and the US to China will increase. Styrene inventory pressure continues. - The strategy includes short - selling BZ and EB on rallies for hedging, and doing reverse spreads on the EB2511 - EB2512 spread on rallies [4][5].
