Report Summary 1. Report Industry Investment Rating - No information provided 2. Core Viewpoints - EB2509 fell 0.84% to close at 7,238 yuan/ton. On the supply side, a new Shandong plant increased output this week, and some plants adjusted their loads. Styrene production increased 2.76% to 369,100 tons, and capacity utilization rose 0.45% to 78.18%. On the demand side, the operating rates of styrene downstream industries varied last week, and the consumption of EPS, PS, and ABS decreased 3.17% to 238,100 tons. In terms of inventory, styrene factory inventory decreased 1.29% to 208,700 tons, East China port inventory decreased 6.42% to 148,800 tons, and South China port inventory increased 16.13% to 18,000 tons. New capacity additions intensify industry competition. Integrated plant profitability is average, and non - integrated plant losses are expected to deepen. Recently, EPS plants on centralized maintenance are about to restart, and some PS and ABS plants plan to increase production, so short - term demand is expected to rise. However, poor downstream demand and expected finished - product inventory accumulation may restrain styrene demand growth [2]. - Styrene spot supply is ample, and total inventory is at a high level compared to the same period. With the decline in crude oil costs, styrene prices are under pressure. Technically, EB2509 should focus on the support around 7,200 [3]. 3.

1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints of the Report - EB2509 fluctuated weakly, closing at 7,397 yuan/ton. On the supply side, last week's styrene production decreased by 1.13% month-on-month to 358,700 tons, and the capacity utilization rate decreased by 0.91% month-on-month to 78.3%. On the demand side, last week's downstream operating rates varied; the consumption of downstream EPS, PS, and ABS increased by 1.45% month-on-month to 237,500 tons. In terms of inventory, styrene factory inventory decreased by 0.66% month-on-month to 208,300 tons, East China port inventory increased by 8.81% month-on-month to 150,700 tons, and South China port inventory decreased by 2.04% month-on-month to 19,200 tons. Currently, domestic styrene is still in a high-production state. This week, the impact of restarted plants will expand, and it is expected that production and capacity utilization will increase slightly. It is the off-season for terminal demand, and downstream demand is mainly for essential needs. Benefiting from the decline in styrene prices, the profits of downstream "Three S" products have recovered; however, due to relatively weak demand, the high inventory of "Three S" finished products is difficult to reduce. The total styrene inventory is at a relatively high level compared to the same period in history, and it is more difficult to reduce inventory. In terms of cost, the US tariffs on the EU are about to be implemented, and Trump said that trade agreements have been reached with Japan and the Philippines. International oil prices are expected to fluctuate in the short term; the supply and demand of pure benzene are expected to remain loose, providing limited support. Pay attention to the support around 7,310 yuan/ton and the resistance around 7,570 yuan/ton on the daily K-line of EB2509 [2] 3.
