苯乙烯开工维持低位，基差持续小涨

1. Report Industry Investment Rating - No information provided in the given content 2. Core Viewpoints of the Report - Pure benzene: Overseas gasoline supply is gradually recovering, leading to high short - term arrival pressure of pure benzene and a faster accumulation rate of port inventory. Domestic cracking load is low, and pure benzene production has declined. Downstream production is in the off - season and has further decreased, with styrene maintaining low - load maintenance, CPL production dropping to the lowest level of the year, phenol production rising, and aniline and adipic acid production fluctuating within a range [2] - Styrene: Styrene is still in the low - production maintenance stage, and the restart plan has been postponed. The port basis has strengthened slightly again, and factory inventory has declined again, but port inventory has not continued to be destocked, and there is still arrival pressure. Downstream enterprise procurement has driven the basis to strengthen. The downstream production shows differentiation. EPS production has a slight rebound in the off - season, but there is still inventory pressure; ABS production has decreased due to continuous finished - product inventory pressure; PS production has continued to rise since the end of the year as the finished - product inventory pressure has been alleviated [2] 3. Summary According to Relevant Catalogs 3.1 Pure Benzene and EB's Basis Structure, Inter - period Spread - The report presents figures related to the basis of pure benzene and EB, including the pure benzene main contract basis, pure benzene spot - M2 paper cargo spread, pure benzene continuous first - contract to continuous third - contract spread, EB main contract basis, and EB continuous first - contract to continuous third - contract spread [7][12][16] 3.2 Pure Benzene and Styrene Production Profits, Domestic and Foreign Spreads - Figures cover various aspects such as naphtha processing fees, pure benzene FOB South Korea - naphtha CFR Japan spread, styrene non - integrated device production profit, pure benzene FOB US Gulf - FOB South Korea spread, pure benzene FOB US Gulf - CFR China spread, pure benzene FOB Rotterdam - CFR China spread, pure benzene import profit, and styrene import profit [19][21][29] 3.3 Pure Benzene and Styrene Inventory, Production Rate - For pure benzene, it shows the inventory in East China ports and the production rate. For styrene, it includes the inventory in East China ports, East China commercial inventory, factory inventory, and the production rate [35][40][41] 3.4 Styrene Downstream Production and Production Profits - Covers the production rates and production profits of EPS, PS, and ABS [46][47][51] 3.5 Pure Benzene Downstream Production and Production Profits - Includes the production rates and production profits of caprolactam, phenol - ketone, aniline, adipic acid, and other downstream products, as well as the production profits of related products such as PA6 regular spinning bright, nylon filament, bisphenol A, PC, epoxy resin E - 51, pure MDI, and polymer MDI [55][62][70] 4. Strategies - Unilateral: No strategy [3] - Basis and inter - period: Consider a positive inter - period spread arbitrage for EB2601 - EB2602 when the price is low [3] - Cross - variety: Consider widening the spread for EB2601 - BZ2603 when the price is low [3]
