On April 16, Shandong styrene market fluctuated horizontally, and today’s quotation was around 9150-9250 yuan / ton. On the cost side, crude oil prices rose, pure benzene and ethylene followed the strong trend, and the international styrene quotation remained strong, providing good cost support for domestic styrene prices. In terms of the plant, Tangshan Xuyang 300000 t / a plant was originally planned to restart on April 20, but now it is in circulation and will be discharged in the near future; Huatai Shengfu 450000 T / a new plant is planned to be put into operation on April 23, and the 400000 T / a PS plant is delayed for 2 to 3 months; overseas South Korea htc650000 T / a plant is originally planned to start on 13-14, but delayed for 4-5 days due to power problems. In terms of inventory, as of April 14, the inventory in East China was 6.9 tons, with a decrease of 6000 tons in the week, and the inventory in ports was 95400 tons, with a decrease of 11100 tons in the week, with a continuous decline. However, starting next week, the domestic overhaul units will be restarted, and new units will be put into production. It is expected that the short-term spot tension in styrene market will be eased. On the downstream side, the price of EPS rose, the wait-and-see mood was strong, and the transaction was general; the price of PS and ABS remained stable, and the transaction was just needed.

To sum up, the cost support of styrene is strong, the inventory is low, the spot is tight, and the price rises. However, as the price of styrene rises, the downstream acceptance of styrene declines, some markets begin to resist, the transaction volume decreases, and the terminal demand continues to be weak. Plant restart and new production capacity are expected to suppress styrene rising space.
