April 16 — The mainstream spot quotation range for xylene in East China is between 7,370 and 7,450 yuan per ton, up 100 yuan per ton from the previous trading day. The aromatics arbitrage window remains open, and the price spreads between PX and mixed xylene, as well as between benzene and toluene, remain wide, providing significant support for product prices. However, due to the continued weakness in crude oil, market sentiment remains subdued, with downstream procurement generally cautious. In the previous trading day, toluene and xylene showed divergent trends, with toluene experiencing a slight decline and xylene a slight increase. In the short term, supply-demand dynamics and cost factors are expected to balance each other out, and the market is projected to continue operating within a narrow range.
