对二甲苯：成本支撑，高位震荡市，PTA：成本支撑，高位震荡市，MEG：上方空间有限，中期仍有压力

1. Report Industry Investment Ratings - No investment ratings are provided in the report. 2. Core Views of the Report - PX is expected to remain in a high - level volatile market supported by cost, and it is recommended to hold long spreads. PTA is also in a high - level volatile market driven by cost, and long spreads operation should be maintained. MEG has limited upside space and faces medium - term pressure, and short spreads operation is advised [1][6][7][8] 3. Summary by Relevant Catalogs 3.1 Market Data - Futures Prices: The closing prices of PX, PTA, MEG, PF, and SC futures on the previous day were 7260, 5110, 3803, 6514, and 432.2 respectively, with daily changes of - 56, - 34, - 44, - 50, and - 3.9, and daily change rates of - 0.77%, - 0.66%, - 1.14%, - 0.76%, and - 0.89% [2] - Spot Prices: The previous day's spot prices of PX CFR China, PTA in East China, MEG, naphtha MOPJ, and Dated Brent were 894 dollars/ton, 5097 yuan/ton, 3678, 530.12 dollars/ton, and 60.98 dollars/barrel respectively [2] - Spot Processing Fees: The previous day's PX - naphtha spread, PTA processing fee, short - fiber processing fee, bottle - chip processing fee, and MOPJ naphtha - Dubai crude spread were 363.88, 361.63, 120.64, 43.68, and - 4.34 respectively [2] 3.2 Market Dynamics - PX: As of January 4, the domestic PX plant operating rate was 90.4%, and the Asian PX operating rate was 80.9% [2] - PTA: The PTA load was 78.1%. Dushan Energy's 250 - million - ton plant restarted, Zhongtai's 120 - million - ton plant restarted at a low load, and Weilian Chemical's 250 - million - ton plant increased its load [3] - MEG: A 200,000 - ton/year syngas - to - ethylene glycol plant in Henan stopped for catalyst replacement at the end of December 2025, with an expected duration of about 2 weeks. A 615,000 - ton/year MEG plant in Kuwait plans to stop for maintenance on January 9, with an expected maintenance duration of about one month. As of January 4, the overall operating load of ethylene glycol in mainland China was 73.73% (a 1.58% increase from the previous period), and the operating load of oxalic acid catalytic hydrogenation (syngas) to ethylene glycol was 75.86% (a 0.51% decrease from the previous period) [3][4] - Polyester: The operating load of large domestic polyester industrial yarn manufacturers remained basically stable, with the overall theoretical operating load of domestic polyester industrial yarn at around 75% (starting from January 2026, the production capacity base of polyester industrial yarn is 3.28 million tons). As of Sunday, the polyester load in mainland China was around 90.8%. The sales of polyester yarn in Jiangsu and Zhejiang were weak, with an average sales rate of less than 40% as of 4 pm. The sales of direct - spun polyester staple fiber were highly differentiated, with an average sales rate of 57% as of 3 pm [4] 3.3 Terminal Market in Jiangsu and Zhejiang - Operating Rates: The comprehensive operating rate of texturing in Jiangsu and Zhejiang dropped to 74%, the comprehensive operating rate of looms dropped to 59%, and the comprehensive operating rate of dyeing remained at 69% [5] - Raw Material Stockpiling: Terminal factories mainly consumed raw material stocks this week, and raw material purchases were mainly for new orders. The raw material purchase volumes of terminal factories varied widely. Currently, the stockpiles of production factories are concentrated between 1 - 3 weeks, and some with more stockpiles still have 1 - 2 months' worth [5] - Orders and Prices: New orders in the weaving sector remained weak, with some foreign trade and spring - summer new orders being slightly followed up. The inventory of grey fabric continued to accumulate. The prices of conventional grey fabric varieties declined locally, and the nominal cash - flow losses of grey fabric widened [5] 3.4 Trend Intensity - The trend intensity of PX and PTA is 1, while that of MEG is 0 [6] 3.5 Views and Suggestions - PX: With strong cost support, long spreads should be held. After the US air - strike on Venezuela on January 3, oil prices are expected to rise in the short - term, supporting the valuation of PX. The 1 - million - ton plant of Fujia Dahua restarted, and India's GAIL purchased Middle - East PX supplies for its planned start - up in March - April. The domestic PX operating rate is 88%. For domestic PTA plants, the processing fee of the 05 contract on the futures market has risen to over 300 yuan/ton. The 2.5 - million - ton plant of Xin Fengming Phase 1 and the 1.2 - million - ton plant of Zhongtai Chemical restarted, and the operating rate is expected to recover. The overall operating rate is expected to remain at around 78% [6] - PTA: In a cost - driven market, the bullish pattern is difficult to disprove for now, and long spreads operation should be maintained. The situation of PTA domestic plants is the same as that mentioned for PX. The profits of polyester filament factories have been declining, leading to a decrease in operating enthusiasm, but the current decline in polyester operating rate is not significant. Coupled with the large - scale export of PTA to India in December, the PTA segment is still in a state of continuous inventory reduction [6][7] - MEG: Although it is affected by the rising valuation of oil and coal prices in the short - term, its medium - term trend remains weak, and short spreads operation is recommended. The domestic ethylene glycol supply remains at a high level of 73.73%. The 200,000 - ton plant of Guangxi Huayi restarted. Overseas, plants in Taiwan, China (720,000 tons), Kuwait (530,000 tons), and Iran (400,000 tons) are under maintenance. The import volume of ethylene glycol is expected to decline marginally in January - February. The operating rate of polyester plants is 90.8%, and the rigid demand for ethylene glycol is decreasing. The polyester load is expected to drop from 89% in January to 84% in February [8]
