March 19 — The mainstream spot quotation range for xylene in East China is between 7,800 and 7,830 yuan per ton. In the previous trading day, toluene and xylene prices experienced a slight upward trend, with significant support from both cost and supply factors. Ongoing geopolitical tensions in the Middle East have driven energy prices to remain elevated, coupled with expectations of tightening domestic spot resources, leading to firm offers from suppliers and an increasing reluctance to sell. However, downstream buyers remain cautious and risk-averse, with limited follow-through in spot transactions, which constrains further upward price movement. The market is expected to exhibit high volatility within the day, with a key focus on actual transaction volumes and changes in downstream procurement patterns.
