化工日报 | 2025-06-18 伊朗EG装置停车增多，EG价格上行 核心观点 市场分析 生产利润方面：乙烯制EG生产利润为-40美元/吨（环比-3美元/吨），煤制合成气制EG生产利润为117元/吨（环比+11 元/吨）。 库存方面：根据 CCF 每周一发布的数据，MEG 华东主港库存为61.6万吨（环比-1.8万吨）；根据隆众每周四发布 的数据， MEG 华东主港库存为56.4万吨（环比-3.4万吨）。上周主港实际到货总数10.8万吨，港口库存平稳略增； 本周华东主港计划到港总数10.0万吨，中性，港口库存预计平稳，关注伊朗装置停车下到港节奏变化。 整体基本面供需逻辑： 供应端，6月国内供应端陆续恢复，整体负荷不高，全月供需结构依旧表现良性去库，但 是仓单陆续注销流出后场内可流转现货将得到一定补充；海外供应方面，关注地缘冲突下伊朗装置停车后到港节 奏变化；需求端，瓶片工厂新增检修计划，需求预期偏弱。后续关注原料大幅反弹后聚酯的减产动作以及乙二醇 大装置重启进度。 策略 单边：短期偏多，关注中东地缘冲突进一步演变 跨期：无 跨品种：无 风险 原油价格波动，煤价大幅波动，宏观政策超预期 期现货方面：昨日EG主 ...

尿素期货价格连续下跌。农业需求部分启动,但采购较为分散,随采随用为主;复合肥夏季高氮肥生产进入尾 声，工业需求不断走弱，生产企业持续累库。出口虽然有序放开，但法检流程推进较慢，部分货源被锁定，周 期内港口库存环比持平。尿素供应充足延续，近期工农业下游跟进乏力，叠加出口需求不及预期，价格松动下 行。 | Mille | 国技斯特 | | | 化工日报 | | --- | --- | --- | --- | --- | | | | 操作评级 | | 2025年06月10日 | | 聚丙烯 | 女女女 | 塑料 | なな女 | 庞春艳 首席分析师 | | 苯乙烯 | 女女女 | РХ | ★☆☆ | F3011557 Z0011355 | | PTA | ★☆☆ | 乙二醇 | ★☆☆ | | | 短纤 | ★☆☆ | 瓶片 | ★☆☆ | 牛卉 高级分析师 | | 甲醇 | ななな | 尿素 | ☆☆☆ | F3003295 Z0011425 | | PVC | なな女 | 烧碱 | ★☆☆ | 周小燕 高级分析师 | | 玻璃 | 文文文 纯碱 | | ★☆☆ | F03089068 Z0016691 | | ...

Group 1: Report Summary - Report Title: Styrene Weekly Report - EB: Weak Supply-Demand Expectations, Focus on Raw Material Resonance Opportunities [1] - Core View: Crude oil is expected to be weak in the medium term under Trump's policy, suppressing the valuation of chemical products. Pure benzene's supply-demand situation shows short-term marginal improvement but still faces pressure, dragging down the styrene price. Styrene's downstream demand is weak, and the supply-demand balance is under pressure. In the medium term, the terminal pressure will gradually emerge due to tariff effects, and high-cost styrene may face resistance. [5] - Strategy Suggestion: Maintain a short position on styrene, with the upper resistance level for the near-month contract at 7300. Sell the EB2506-C-8000 option. [6] Group 2: Pure Benzene 2025 Production Plan - Multiple companies in various provinces have plans to expand pure benzene, styrene, and their downstream production capacities in 2025, including Shandong Yulong Petrochemical, ExxonMobil in Guangdong, etc. [8] March - May 2025 Device Dynamics - Many pure benzene production devices are scheduled for maintenance from March to May 2025, resulting in a net reduction in supply and demand during this period, with a slight inventory drawdown. [10][11] Supply, Inventory, and Price - From January to April this year, the cumulative pure benzene production was 718.5 million tons, a year-on-year increase of 6.11%. As of May 9, the capacity utilization rate was 73.25%, and the weekly production was 401,600 tons. The port inventory remained at 120,000 tons without significant change. [45] - South Korea's exports of pure benzene to China have remained at a high level, and the inventory drawdown has been slow due to high production and imports. [28][34] Downstream Situation - The weighted average operating rate of pure benzene downstream industries has rebounded recently with the restart of styrene devices. However, the overall profit is weak, with adipic acid and caprolactam still experiencing significant losses, and styrene's profit has improved but remains below the break-even point. [46][57] Group 3: Styrene Futures and Spot Market - The spot price and basis of styrene show certain fluctuations, and the monthly spread and registered warehouse receipts also have corresponding changes. [63] Supply and Profit - The monthly and weekly production of styrene and the operating rate show upward trends in general. The non-integrated and integrated profits of styrene and the styrene-pure benzene spread also fluctuate. [68][71][72] Import and Export - With the shutdown of multiple styrene devices in Asia, China has gradually shifted from a net importer to a net exporter of styrene in the past five years, and exports have continued from April to May. [80] Inventory - The port inventory of styrene has continued to decline, with relatively limited year-on-year pressure, while the factory inventory is under pressure. [81] Downstream Situation - The high capacity growth rate of 3S (PS, EPS, ABS) has intensified competition, and the high production has supported the demand for styrene. However, the industry is facing profit compression, and the current downstream is characterized by low profit and high inventory, indicating limited terminal demand. [86][90] - The prices of 3S products have weakened, but the estimated profit has strengthened due to the significant fluctuations in styrene prices. [91] - The high production of 3S has led to a significant increase in inventory, indicating resistance in demand transmission, and the support for styrene demand may weaken marginally. [96][99] Terminal Market - After the implementation of tariffs, exports are likely to be restricted, and domestic demand depends on subsidy policies. The domestic and export sales of home appliances such as air conditioners, refrigerators, and washing machines show certain trends. [100]
