Report Industry Investment Rating No relevant content provided. Core Viewpoints - In the short - term, the domestic pure benzene has a large real - time arrival pressure, with port inventory accelerating accumulation. The overseas gasoline shortage has passed, but the price difference between the US and South Korea in the pure benzene market is still being repaired. Downstream提货 is weak, and downstream开工 is further decreasing in the off - season. Styrene maintains low - load maintenance, CPL开工 drops to the lowest level of the year, phenol开工 rebounds, and aniline and adipic acid开工 fluctuate within a range [3]. - For styrene, port inventory further declines, and the port basis remains strong. Styrene maintains low - level operation, port inventory continues to decrease, and downstream提货 is acceptable. The downstream开工 shows differentiation. EPS开工 rebounds slightly in the off - season but still has inventory pressure; ABS开工 decreases due to continuous finished - product inventory pressure; PS开工 continues to rise at the end of the year as the finished - product inventory pressure eases [3]. Summary by Directory 1. Pure Benzene and EB's Basis Structure, Inter - period Spread - The pure benzene main contract basis is - 130 yuan/ton (+12), and the spot - M2 paper cargo spread is - 150 yuan/ton (+35 yuan/ton).

Report Industry Investment Rating - Not provided in the content Core Viewpoints - In the short term, the concentrated arrival of pure benzene in China has led to a rapid increase in port inventories and a weakening of the basis. The domestic production start - up continues to rise, while the downstream start - up is weak. For styrene, port inventories continue to decline due to export boosts and low domestic start - up, but there is a resumption expectation at the end of November. Recently, the increase in pure benzene inventory and the decrease in styrene inventory are conducive to the short - term expansion of the EB - BZ spread [3] Summary by Directory 1.

Report Industry Investment Rating No relevant information provided. Core Viewpoints - For pure benzene, port inventory declined slightly. Low开工 rates of downstream styrene, CPL, and adipic acid dragged down demand, leading to a weak port basis. The domestic开工 rate of pure benzene decreased at an accelerating pace, and attention should be paid to the impact of European and American sanctions on Russian oil on refinery loads [3]. - For styrene, there were still short - term maintenance plans, and new device launches such as Jihua and Guangxi Petrochemical had an impact. Downstream开工 changed little, but提货 was average, and the finished product inventory pressure of the three major hard plastics remained high, resulting in continuous port inventory pressure [3].

Report Industry Investment Rating No relevant content provided. Core Viewpoints - Korean petrochemical companies may cut 270 - 370 million tons of naphtha cracking capacity, potentially affecting EB supply more than BZ as Korean styrene accounts for 16% of overseas styrene capacity while Korean cracked pure benzene only accounts for 3.5% of overseas pure benzene capacity [3]. - For pure benzene, port inventory is slightly decreasing from a high level but still at a high absolute level, and the port basis is waiting to strengthen further. Attention should be paid to the inventory pressure in the CPL - PA6 - nylon industry chain and the MDI inventory pressure in the aniline downstream [3]. - For styrene, port inventory is accumulating due to high current operating rates, but there are concentrated maintenance plans in September, which may lead to destocking. The operating rates of EPS and PS in the downstream continue to rise, but inventory has not continued to decline, indicating slow downstream follow - up, and ABS maintains a state of high inventory and low operating rate [3].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - BZ futures maintain a large premium, reflecting the contango structure of high - inventory pricing. The strong downstream demand for pure benzene has led to a decline in pure benzene port inventory from its high level. However, the supply pressure from South Korea's exports to China and high domestic production have kept the pure benzene processing fee in a weak consolidation. For styrene, the port inventory has further increased, and the EB basis has further declined. Domestic EB maintains high - level production, while the demand is dragged down by the low operation rates of EPS and PS [3]. Summary by Catalog 1. Pure Benzene and EB's Basis Structure, Inter - period Spread - Relevant data includes pure benzene's main basis, the spread between pure benzene spot and M2 paper goods, the spread between the first - and third - consecutive contracts of pure benzene, the trend and basis of the EB main contract, and the spread between the first - and third - consecutive contracts of styrene [8][12][17] 2.
