1. Report Industry Investment Rating - No information provided regarding the report industry investment rating. 2. Core Viewpoints of the Report - The news that the US informed Israel of its preparations for actions against Iran led to a rise in crude oil prices, driving cost - based increases in pure benzene and styrene [3]. - The pure benzene port inventory rebounded slightly at the beginning of the week. Although the arrival pressure eased, downstream提货 declined. The overall downstream start - up was okay, with non - styrene pure benzene downstream start - up rising, especially aniline start - up which increased significantly due to MDI restart. Domestic pure benzene start - up decreased further, and there are concerns about potential changes in overseas supply [3]. - For styrene, the lowest point of domestic start - up may have passed, with some plants having restart expectations. The port inventory increased for the first time this week. The downstream start - up was still okay, with inventory pressure further relieved [3]. 3. Summaries According to Related Catalogs I.
