聚酯周报：原油延续下跌趋势，聚酯供给端有所收缩-20251020

1. Report Industry Investment Rating - The investment view is "oscillating", with no obvious driving force, and it is expected to mainly oscillate [4] 2. Core View of the Report - The report analyzes the polyester industry from multiple aspects including supply, demand, inventory, etc. It points out that the supply side of polyester has shrunk, the downstream load of polyester remains at about 90%, and the PTA port inventory has slightly increased. The PTA basis has stabilized, but the profit has continued to shrink. The PX - naphtha spread is at $250, and the PTA processing fee remains at around 200 yuan. The PTA price is at a neutral - low level, and the absolute price has further declined due to the fall in crude oil prices. The overall market is expected to oscillate mainly due to the lack of obvious driving factors [4] 3. Summary According to Relevant Catalogs 3.1 Main Views and Strategy Overview - Supply: It is bearish. The trade war may escalate, slightly affecting China's crude oil imports. The supply of domestic PTA devices has slightly shrunk, the PTA basis has stabilized, the PX device operating rate is stable, the cost has weakened, and although the PXN has expanded, polyester has followed the decline in crude oil [4] - Demand: It is bearish. The downstream load of polyester remains at about 90%, the inventory of polyester factories is optimistic, and it is necessary to pay attention to whether the weaving can maintain the load after the "Golden September and Silver October" [4] - Inventory: It is neutral. The port inventory of PTA has slightly increased, and the physical goods in the Ningbo direction are slightly in short supply [4] - Basis: It is bearish. The PTA basis has quickly stabilized, the PTA profit has continued to shrink, and the liquidity in the PTA market is still very loose [4] - Profit: It is bearish. The spread between PX and naphtha is $250, the PTA processing fee remains at around 200 yuan, and the PTA processing fee has expanded [4] - Valuation: It is neutral. The PTA price is at a neutral - low level. After the end of the domestic maintenance season, the reforming devices are gradually recovering, and the absolute price of PTA has further declined due to the fall in crude oil prices [4] - Macro Policy: It is neutral. On October 15, Fed Chairman Powell hinted that the Fed is planning to cut interest rates by 25 basis points later this month [4] - Investment View: It is oscillating. There is no obvious driving force, and it is expected to mainly oscillate [4] - Trading Strategy: For unilateral trading, it is recommended to wait and see, and pay attention to geopolitical risks [4] 3.2 Oil Product Fundamentals Overview - Macro Situation: On October 15, Fed Chairman Powell said that the US economy seems to be in a stable state, but the government shutdown may affect data collection. On October 17, major European stock indexes fell in early trading, with concerns about the banking industry spreading, and the European defense stocks also attracted attention [8] - Gasoline: The shutdown of the US government may affect demand in the off - season. The North American refinery load has declined, the total gasoline inventory has decreased by 1.6 million barrels, indicating strong terminal demand. The price of high - octane aromatics has remained relatively stable, and its spread with RBOB gasoline has remained stable at 68 cents [22] 3.3 Aromatic Hydrocarbon Fundamentals Overview - Supply Increase: With the commissioning of Yulong Petrochemical, the supply of MX is expected to increase in October. The future domestic xylene capacity will continue to be put into production at a high speed, with 1.7 million tons of xylene devices in Jiujiang Petrochemical, Huajin Aramco, and Zhongsha Gulei waiting to be put into production in 2026 [62] - Market Situation: The cross - regional arbitrage space for aromatics has opened, but physical trade has not occurred. The profit of selective disproportionation has declined, and the pure benzene price has suppressed the disproportionation profit. After the end of the maintenance season, the floating spread of PX has continued to weaken, the operating rate has significantly recovered, and the load has reached a very high level [40][54][62] - Outlook: Mixed xylene is facing continuous downward pressure. The profit of both gasoline reforming and aromatic hydrocarbon reforming has recovered, but the PTA supply side has shrunk, the processing fee has remained low, and the industry profit is still restricted by over - capacity [52][66] 3.4 Polyester Fundamentals Overview - Ethylene Glycol: The supply of ethylene glycol has increased, and the price is running weakly. The inventory in East China ethylene glycol ports is still at a low level, the arrival volume at ports is limited, the import volume in the overseas market is expected to decline, and the new domestic devices have put pressure on the price. The coal - to - ethylene glycol operating rate has continued to recover, and the profit has been repaired [80] - Gasoline: The load of major refineries may decline due to port transportation [81] - Polyester: Polyester continues to maintain a high load, but the weaving load may decline. The polyester production has increased, and the downstream has entered the off - season [88][90]
