化工周报：成本端反弹，国内供应仍在高位-20251026

Report Industry Investment Rating - Unilateral: Neutral; for spreads, EG2601 - EG2605 reverse spread; for cross - variety, none [4] Core View - This week, the price center of ethylene glycol fluctuated upward, and the basis strengthened significantly. The domestic ethylene glycol supply is still at a high level, while overseas supply losses remain high. Recently, the downstream of polyester has moderately improved, boosting market sentiment [1][3] Summary by Directory Price and Spread - This week, the ethylene glycol price center fluctuated upward, and the basis strengthened significantly. At the beginning of the week, the ethylene glycol port inventory continued to rise, putting pressure on the ethylene glycol futures. In the middle of the week, with the intensification of geopolitical conflicts, crude oil rebounded. Affected by the possible delay of Saudi arrivals and the cancellation of the loading of some Iranian cargoes, the ethylene glycol price rose rapidly [1] Supply - The overall operating load of ethylene glycol in mainland China is 73.28% (a 3.88% decrease from last week), among which the operating load of ethylene glycol produced by oxalic acid catalytic hydrogenation (syngas) is 82.21% (a 0.32% increase from last week). With the maintenance and shutdown of plants such as Shenghong, Fujian Refining & Petrochemical, and Zhongke, the total EG load declined from a high level this week. Recently, the coal - based production has decreased, but the reduction of supply - side plants is not obvious, and the supply is still at a high level [1] Demand - The load of textile looms in Jiangsu and Zhejiang is 75.0% (a 6.0% increase from last week), the load of texturing machines in Jiangsu and Zhejiang is 84.0% (a 4.0% increase from last week), the polyester operating rate is 91.40% (unchanged from last week), and the direct - spinning filament load is 92.40% (a 0.40% decrease from last week). The inventory days of POY, FDY, and DTY have decreased significantly. The operating rate of polyester staple fiber plants is 94.3% (unchanged), and the inventory days of polyester staple fiber plants' equity inventory have decreased. The operating rate of bottle - chip plants is 73.2% (a 0.8% increase from last week). With the cooling weather and the start of the Double Eleven sales, domestic orders have improved significantly this week. The load of looms and texturing machines has rebounded significantly, and the raw material rebound has also driven centralized restocking. The filament inventory has been significantly reduced. However, since the inventory is still at a seasonal high, the current raw material inventory of weaving mills is not high. Attention should be paid to whether the Sino - US tariff negotiations at the end of the month will bring favorable factors to drive external demand. Currently, the inventory of polyester plants is not high, and the cash - flow profit is acceptable. The average load of polyester in October and November is expected to be slightly increased [2] Inventory - According to the data released by CCF every Monday, the inventory of MEG in the main ports of East China is 57.9 tons (a 3.8 - ton increase from last week); according to the data released by Longzhong every Thursday, the inventory of MEG in the main ports of East China is 48.3 tons (a 1.0 - ton decrease from last week). According to CCF data, the total planned arrivals at the main ports of East China this week are 5.3 tons, and the planned arrivals at the secondary ports are 6.3 tons. As of October 23, the total inventory of MEG in the main ports of East China is 48.3 tons, 3 tons lower than on Monday this week and 1 ton lower than on Thursday last week [3]
