PTA：原料强势支撑下，PTA偏暖震荡，MEG：供需格局尚可，MEG短期延续低位反弹

Group 1: Report Summary - The report is a polyester weekly report from Zhengxin Futures, dated May 12, 2025, focusing on the PTA and MEG markets [2] - It analyzes the cost, supply, demand, and inventory aspects of the polyester industry chain and provides investment strategies and key points to watch [6] Group 2: Industry Investment Rating - No industry investment rating is provided in the report Group 3: Core Views - PTA is expected to have a warm and oscillating trend in the short - term due to strong raw material PX performance and continuous de - stocking, despite some relief in the tight supply - demand pattern [6] - MEG is likely to continue its rebound in the short - term as the supply - demand pattern is favorable with expected declines in both domestic production and imports and high polyester开工率 [6] Group 4: Summary by Directory 4.1 Upstream Industry Analysis - Market Review: International oil prices fell due to OPEC+ increasing production and positive signals from US - Iran negotiations. PX had a narrow - range repair due to poor cost support, continuous de - stocking of downstream PTA, low processing fees, and declining capacity utilization. As of May 9, Asian PX closed at $786/ton CFR China, up $40/ton from April 30 [18] - PX开工率: The weekly average PX capacity utilization rate was 81.94%, a 4.5% increase from last week. Some devices had restarts, but there were also load - reducing situations such as catalyst replacement and planned maintenance [21] - PX Processing Fees: As of May 9, the PX - naphtha price difference was $216.7/ton, up $34.42/ton from April 30. Low previous processing fees and non - planned load reduction promoted the repair of processing fees [23] 4.2 PTA Fundamental Analysis - Market Review: After the holiday, PTA opened slightly lower, then the international oil price rebounded, and with supply reduction from device maintenance and a warming commodity sentiment, the PTA price center strengthened. As of May 9, the PTA spot price was 4,720 yuan/ton, and the spot basis was 2509 + 155 [26] - PTA Capacity Utilization: The weekly average PTA capacity utilization rate dropped to 74.48%, a 2.53% decrease from the previous week. In May, there are more planned device maintenance and some planned restarts, with an expected decline in capacity utilization [30] - Supply - Demand Balance and Processing Fees: Multiple device maintenance led to supply reduction and continuous de - stocking of the balance sheet, causing a significant increase in PTA processing fees. Next week, with device restarts, processing fees are expected to decline slightly [33] - Inventory Expectation: In May, with many PTA device maintenance plans and a co - existence of maintenance and restart in the polyester end, the supply - demand will continue the de - stocking pattern [34][36] 4.3 MEG Fundamental Analysis - Market Review: Affected by the sharp drop in crude oil during the holiday, MEG opened lower after the holiday. With the improvement of the macro - situation, the market rebounded from the low level and fluctuated around 4,300 yuan/ton. As of May 9, the closing price in Zhangjiagang was 4,300 yuan/ton, and the delivered price in the South China market was 4,390 yuan/ton [39] - MEG Capacity Utilization: The total domestic MEG capacity utilization rate this week was 63.46%, a 0.47% increase from the previous week. There are multiple device maintenance and new device start - up plans in May, with most restarts concentrated around the end of the month [42] - Port Inventory: As of May 8, the total MEG port inventory in the main ports of East China was 69.2 tons, an increase of 1.6 tons from May 6. The arrival was okay, but the shipment was dull, leading to a slight increase in inventory [47] - Production Profits: Due to the slight increase in the MEG price and different declines in raw material prices, the sample profits of all MEG production processes increased. As of May 9, the profit of naphtha - based MEG was - $105.8/ton, up $19.55/ton from last week; the coal - based profit was - 203.58 yuan/ton, up 43.32 yuan/ton from last week [50] 4.4 Downstream Demand Analysis - Polyester Capacity Utilization: The weekly average polyester capacity utilization rate was 91.49%, a 0.1% decrease from the previous week. Although some devices increased their loads, the overall production and capacity utilization declined slightly due to previous maintenance [53] - Polyester Production: In May, with a co - existence of maintenance and restart and a higher restart capacity than the maintenance capacity, the monthly polyester production is expected to increase slightly [56] - Capacity Utilization of Different Products: The weekly average capacity utilization rate of polyester filament was 92%, a 0.28% decrease from the previous week; that of polyester staple fiber was 86.94%, a 0.26% increase; that of fiber - grade polyester chips was 85.75%, a 2.99% decrease [59] - Polyester Product Inventory: After the holiday, the market trading was average, and the finished - product inventory of polyester filament factories gradually accumulated [60] - Polyester Cash Flow: With the expected increase in the cost side, the polyester cash flow may be further compressed, with local cash flow repair for some products and compression for DTY [63] - Weaving Industry: As of May 8, the comprehensive starting rate of chemical fiber weaving in the Jiangsu and Zhejiang regions was 60.82%, a 5.73% increase from the previous period. The average order days of terminal weaving were 10.17 days, an increase of 0.48 days from last week. However, foreign trade orders were sporadic, and there is a risk of a decline in the starting rate in the future [67] 4.5 Polyester Industry Chain Fundamental Summary - Cost Side: International oil prices fell, and PX had a narrow - range repair due to factors such as downstream de - stocking and low processing fees [69] - Supply Side: The PTA capacity utilization rate decreased, and the MEG capacity utilization rate increased slightly [69] - Demand Side: The polyester capacity utilization rate decreased slightly, and the weaving starting rate increased, but the order situation was not optimistic [69] - Inventory: PTA maintained a tight supply - demand balance, and MEG port inventory increased slightly [69]
