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]. Summary by Directory I. Pure Benzene and EB's Basis Structure and Inter - Period Spreads - Figures include pure benzene's main contract basis, spot - M2 paper cargo spread, and inter - period spreads between contracts, as well as EB's main contract basis and inter - period spreads [9][13][17] II. Pure Benzene and Styrene Production Profits and Domestic - Foreign Spreads - Figures cover naphtha processing fees, pure benzene's FOB spreads in different regions, styrene's non - integrated production profits, and import profits of pure benzene and styrene [20][23][33] III. Pure Benzene and Styrene Inventory and Operating Rates - Figures show pure benzene's East China port inventory and operating rate, and styrene's East China port inventory, commercial inventory, factory inventory, and operating rate [40][42][45] IV. Styrene Downstream Operating Rates and Production Profits - Figures present the operating rates and production profits of EPS, PS, and ABS in the styrene downstream [52][54][57] V. Pure Benzene Downstream Operating Rates and Production Profits - Figures display the operating rates and production profits of caprolactam, phenol - acetone, aniline, adipic acid, and other downstream products of pure benzene [60][67][71]

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. Production Profits and Domestic - Foreign Spreads of Pure Benzene and Styrene - It involves data such as naphtha processing fee, the price difference between pure benzene FOB South Korea and naphtha CFR Japan, the production profit of non - integrated styrene plants, and the import profits of pure benzene and styrene [21][23][28] 3. Inventory and Operation Rates of Pure Benzene and Styrene - Pure benzene's East China port inventory and operation rate are presented, along with styrene's East China port inventory, commercial inventory, factory inventory, and operation rate [34][36][39] 4. Operation and Production Profits of Styrene's Downstream - Data on the operation rates and production profits of EPS, PS, and ABS are provided [45][49][50] 5. Operation and Production Profits of Pure Benzene's Downstream - Information includes the operation rates and production profits of caprolactam, phenol - acetone, aniline, adipic acid, PA6, nylon filament, bisphenol A, PC, epoxy resin E - 51, pure MDI, and polymer MDI [53][57][64] Strategies - Unilateral: Observe pure benzene and styrene [4] - Basis and Inter - period: For near - month BZ paper goods and far - end BZ2603 futures, conduct reverse arbitrage when the price is high [4] - Cross - variety: Shrink the EB - BZ price difference when it is high [4]
