Report Industry Investment Rating - Unilateral: Neutral; pay attention to the PL01 - 02 high - price reverse spread after the restart of the main PDH [3] - Cross - period: After the restart of the main PDH, focus on the PL01 - 02 high - price reverse spread [3] - Cross - variety: None [3] Core View - On the supply side, two PDH units of Wanhua Penglai and Hebei Haiwei restarted and increased production. There is still a load reduction at Binhua, the PDH unit of Qingdao Jinneng continues to be under maintenance, Shandong Zhenhua is expected to restart in the short term, and the PDH units of Donghua Zhangjiagang and Ningbo Jinfa in the East China region continue to be shut down [2] - On the demand side, the profits of propylene downstream are greatly compressed, and the overall start - up rate has decreased month - on - month. Among them, the start - up rate of PP has decreased significantly, the price difference between PP and propylene has narrowed significantly, and the start - up of powder materials is difficult to recover. Due to the shutdown and maintenance of the plant, the start - up of phenol - acetone has also decreased significantly. The PO unit of Qixiangtengda is shut down for maintenance, and the start - up of propylene oxide is expected to decline. The profit of butanol and octanol is good, and the start - up rate continues to rise. After the restart of the Wanhua acrylic acid unit, the start - up rate has the largest increase. Downstream purchases at low prices, and the demand support has improved, but the downstream cost pressure has not been relieved, which may suppress the upward space of propylene [2] - On the cost side, the geopolitical situation is still volatile, the center of oil prices has rebounded, and the price of propane in the external market has continued to strengthen, so the cost side still has support [2] Summary by Directory 1. Propylene Basis Structure - The closing price of the propylene main contract is 6462 yuan/ton (+17), the spot price of propylene in East China is 6475 yuan/ton (+25), the spot price of propylene in North China is 6615 yuan/ton (+65), the basis of propylene in East China is 13 yuan/ton (+8), and the basis of propylene in North China is 153 yuan/ton (+48) [1] 2.
