化工日报 | 2025-05-15 市场情绪延续乐观，PXN大幅上涨 市场要闻与数据 5月14日，聚酯产业链商品全线上涨，MEG/PX/PTA/PF/PR主力合约分别上涨3.68%、2.96%、2.87%、3.02%、3.23%。 上涨的主要原因是：一方面近期宏观情绪较好，上个周末中美双方在瑞士日内瓦举行的会谈结果超预期，降低关 税对聚酯需求端利好明显，订单和长丝产销好转，同时原油价格反弹持稳，带动下游能化品整体反弹。 另外基本面方面，在聚酯高负荷的支撑下，PTA、MEG等聚酯原料4、5月连续去库，PTA更是连续两个月去库50 万吨附近，PX现货采购也偏紧；下游方面，PF和PR前几日在原料快速上涨中加工费压缩严重，周三PR主流供应商 缩减合约，因此涨幅高于原料。 市场分析 成本端，中美会谈结果超预期，在此宏观利好下，商品氛围整体明显回暖，原油价格大幅上涨，带动下游能化品 整体反弹。 汽油和芳烃方面，汽油裂解近期有所反弹，但季节性表现仍弱于前两年，后续随着汽油需求旺季到来可能会季节 性好转，但整体在新能源替代的背景下预计汽油裂解价差上涨空间有限。芳烃方面，今年的调油需求已不值得过 多的期待。国内外间歇性调油需求 ...
