Report Summary 1. Report Industry Investment Rating - The report implies a bearish outlook for the styrene industry, suggesting that the styrene futures 2510 contract may maintain a weak and volatile trend [7]. 2. Core View of the Report - The cost support for styrene from upstream pure benzene is weakening, while the domestic styrene production capacity utilization rate is rising, output is slightly increasing, and downstream consumption is sluggish. With only rigid demand support, port inventories have slightly increased, and future demand needs improvement. Due to these bearish industry factors, the styrene futures 2510 contract is expected to maintain a weak and volatile trend [2][6][7]. 3. Summary by Relevant Catalogs Pure Benzene's Weak Impact on Styrene Cost Support - The domestic pure benzene supply - demand pattern is weak. External import pressure is high. From January to June 2025, South Korea's pure benzene exports to the US decreased by 450,000 tons (a 90% drop), while exports to China increased by 620,000 tons (a 79% increase). China's cumulative pure benzene imports in the first half of 2025 were 2.7306 million tons, a 56.19% increase year - on - year. In July, the single - month import volume returned to 500,000 tons, and the annual import volume may exceed 5 million tons [3]. - Domestic pure benzene production is growing. As of the end of August, the domestic petroleum benzene capacity utilization rate was 79.18%, a slight 0.19 - percentage - point increase month - on - month, and the output was 451,900 tons, a 0.24% increase month - on - month. Given the large future supply pressure, the weak price trend of pure benzene is hard to change, and its cost support for styrene is weakening [3]. Rising Supply Pressure of Styrene - In August 2025, China's styrene plant capacity utilization rate was about 79.95%, a 1.31% increase month - on - month, and the monthly output was expected to be 1.6217 million tons, a 1.31% increase month - on - month [4]. - As of September 5, the weekly capacity utilization rate of Chinese styrene plants was 79.74%, a 1.67% increase week - on - week, with a total output of 376,500 tons, a 0.79 - thousand - ton increase week - on - week and a 2.14% increase month - on - month. In September, although there are maintenance plans for some enterprises, the supply increase from new device commissioning and the maintenance loss are basically balanced, and the output may remain stable [4]. Downstream Demand Needs Improvement - Since September, domestic styrene downstream demand has been mainly supported by rigid demand, showing relative stability but lacking incremental momentum. The operating rates of some downstream products such as EPS, PS, ABS, and styrene - butadiene rubber have increased year - on - year, but the profitability of downstream enterprises is generally under pressure, mostly at the break - even point [5]. - Downstream procurement is mainly for rigid replenishment, with low initiative to stock up, having limited impact on market boosting. As of early September 2025, the total sample inventory of styrene ports in Jiangsu was 196,500 tons, a 9.78% increase week - on - week. The commercial inventory was 96,500 tons, a 14.88% increase week - on - week. In the short term, the demand side is difficult to improve significantly [5].

1. Report Industry Investment Rating - No relevant information provided 2. Core Viewpoints - EB2510 fell 1.20% to close at 6,934 yuan/ton. On the supply side, last week's styrene production decreased by 0.59% to 368,600 tons, and the capacity utilization rate decreased by 0.46% to 78.07%. On the demand side, last week's downstream styrene operating rates mostly declined, and the consumption of the EPS, PS, and ABS industries decreased by 0.18% to 270,100 tons. In terms of inventory, styrene factory inventory increased by 2.35% to 211,300 tons, East China port inventory increased by 9.78% to 179,000 tons, and South China port inventory decreased by 11.11% to 24,000 tons. In September, multiple large - scale plants will undergo centralized maintenance, which will have a greater impact than the planned new 600,000 - ton Jilin Petrochemical plant, and the industry's supply pressure may ease. This week, the 320,000 - ton Xinpu Chemical plant is planned to stop for maintenance, and production and capacity utilization are expected to decline month - on - month. The downstream industry's operating load is expected to be slightly adjusted. Currently, low downstream profits and high inventory still restrain the growth of styrene demand. In the short term, the supply - demand contradiction is difficult to improve, and inventory pressure remains high. In terms of cost, global crude oil supply and demand are weak, and the Russia - Ukraine peace talks are continuing, but the short - term deterioration of the Middle East geopolitical situation still provides some support for oil prices. The short - term market trend is weak, and technically, EB2510 should pay attention to the support around 6,800 [2][3] 3.

1. Report Industry Investment Rating No relevant content provided 2. Core Viewpoints - EB2509 dropped and then rebounded, closing at 7,230 yuan/ton. In the short - term, the domestic market has no new shutdown devices, and the impact of restarted and capacity - increased devices is expanding, with an expected increase in supply. The downstream industry has both shutdown and restarted devices, and the terminal demand lacks positive factors, so the styrene consumption is difficult to grow significantly. The supply - stronger - than - demand situation in the spot market is expected to continue, and the inventory pressure may continue to rise. In terms of cost, the supply - stronger - than - demand situation of crude oil continues, and the international oil price is expected to fluctuate weakly. The main contract of styrene is about to change. EB2509 is dominated by the delivery logic, with a short - term fluctuation range expected between 7,150 - 7,360 yuan/ton; EB2510 is supported by the peak season in September and maintenance expectations, and technically, attention should be paid to the support around 7,130 yuan/ton and the pressure around 7,380 yuan/ton [2] 3.

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.

Report Industry Investment Rating - Not provided Core Viewpoints - EB2508 rose 2.73% to close at 7,520 yuan/ton. On the supply side, last week's styrene production decreased by 0.05% to 366,600 tons, and the capacity utilization rate decreased by 0.05% to 80.03%. On the demand side, the consumption of the main downstream products (EPS, PS, ABS) decreased by 5.21% to 243,600 tons. In terms of inventory, the factory inventory decreased by 2.99% to 194,000 tons, the inventory at East China ports increased by 12.85% to 1.115 million tons, and the inventory at South China ports decreased by 40% to 90,000 tons. After the centralized restart of large - scale plants, the styrene operating rate has remained high. This week, a 300,000 - ton plant in Hebei is planned to shut down, while a 350,000 - ton plant in the Northeast and a 120,000 - ton plant in Central China will restart, with production and capacity utilization expected to rise slightly. In the off - season of terminal demand, downstream demand is mainly for rigid needs. The finished product inventory of downstream "Three S" products is high, and the profits of EPS and PS are still low; although the profit of ABS has recovered due to weak costs, the demand has not improved. The total inventory is at a relatively high level in the same period of history, and it is more difficult to destock. In terms of cost, the US may maintain sanctions on some oil - producing countries, and the situation in the Red Sea region has deteriorated, causing recent international oil prices to fluctuate strongly; the supply - demand of pure benzene is expected to remain loose, and its price lacks support. The market is trading on the expectation of the exit of backward production capacity, and the industrial products sector is mostly rising. Pay attention to the resistance around 7,600 on the EB2508 contract [2].
