苯乙烯基差再度小幅走强

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - Overseas gasoline supply is gradually recovering, leading to significant short - term arrival pressure on pure benzene, with an accelerated accumulation rate of port inventory. Downstream operations remain at a low level during the off - season. Styrene is under maintenance with low load, and CPL operation is further declining at a low level. Although the operations of phenol, aniline, and adipic acid have slightly increased, terminal demand is still weak [3]. - The port basis of styrene continues to strengthen slightly, but the port inventory does not continue to decline, and there is still arrival pressure. The procurement by downstream enterprises drives the basis to strengthen. Attention should be paid to their enthusiasm for holding goods during the off - season. Styrene is still in the low - operation stage of maintenance, and the resumption plan is postponed. However, the downstream operation during the off - season is still low. The operation of EPS with obvious seasonality continues to decline, the operation of PS rebounds but there is still inventory pressure, and the finished - product inventory of ABS still has pressure while the operation remains at a low level [3]. 3. Summary of Each Directory I. Basis Structure and Inter - period Spread of Pure Benzene and EB - Pure benzene: The main basis of pure benzene is - 116 yuan/ton (+3), and the spread between East China pure benzene spot and M2 is - 155 yuan/ton (- 15 yuan/ton) [1]. - Styrene: The main basis of styrene is 115 yuan/ton (+64 yuan/ton) [1]. II. Production Profit and Domestic - Foreign Spread of Pure Benzene and Styrene - Pure benzene: The processing fee of pure benzene CFR China is 102 dollars/ton (+0 dollars/ton), the processing fee of pure benzene FOB South Korea is 92 dollars/ton (+0 dollars/ton), and the price difference between the US and South Korea is 184.9 dollars/ton (+15.1 dollars/ton). The production profit of downstream products varies, such as - 550 yuan/ton (+85) for caprolactam, - 827 yuan/ton (- 225) for phenol - acetone, 753 yuan/ton (+254) for aniline, and - 1218 yuan/ton (+34) for adipic acid [1]. - Styrene: The non - integrated production profit of styrene is - 67 yuan/ton (+94 yuan/ton), and it is expected to gradually compress. The import profit and other relevant spreads are presented in the report [1][34]. III. Inventory and Operating Rate of Pure Benzene and Styrene - Pure benzene: The port inventory of pure benzene is 22.40 tons (+6.00 tons), and the operating rate of downstream products shows different changes, with the caprolactam operating rate at 86.68% (- 1.54%), the phenol operating rate at 81.00% (+2.00%), the aniline operating rate at 77.19% (+1.51%), and the adipic acid operating rate at 59.40% (+3.90%) [1]. - Styrene: The East China port inventory of styrene is 160,600 tons (- 3,600 tons), the East China commercial inventory is 96,400 tons (+2,200 tons), and the operating rate is 67.3% (- 1.7%) [1]. IV. Operating Rate and Production Profit of Styrene Downstream Products - EPS: The production profit is 17 yuan/ton (+16 yuan/ton), and the operating rate is 54.75% (- 1.52%) [2]. - PS: The production profit is - 83 yuan/ton (+16 yuan/ton), and the operating rate is 57.60% (+1.70%) [2]. - ABS: The production profit is - 644 yuan/ton (- 44 yuan/ton), and the operating rate is 71.20% (- 1.20%) [2]. V. Operating Rate and Production Profit of Pure Benzene Downstream Products The production profit and operating rate data of caprolactam, phenol - acetone, aniline, and adipic acid are as mentioned above in the production profit and inventory and operating rate parts [1]. Strategy - Unilateral: None. - Basis and Inter - period: Conduct long inter - period spread trading for EB2601 - EB2602 at low prices. - Cross - variety: Expand the spread of EB2601 - BZ2603 at low prices [4].
