Ethylene Glycol Futures Market Data Change Analysis - Main Contract and Basis: The price of the main ethylene glycol futures contract rose from 3,808 yuan/ton to 3,884 yuan/ton, an increase of 76 yuan or 2.0%, while the spot price in East China remained stable at 3,845 yuan/ton The basis (spot minus futures) was -39 yuan/ton, indicating a deeper discount and an expanded premium of the futures market relative to the spot, possibly driven by the capital side [2]. - Open Interest and Trading Volume: The open interest of the main contract decreased from 353,300 lots to 317,468 lots, a decrease of 35,832 lots or 10.14%, suggesting that some long or short positions were closed The trading volume increased significantly from 164,315 lots to 282,100 lots, an increase of 117,785 lots or 71.68%, indicating increased market trading activity, but the decrease in open interest implies that short - term speculative behavior is dominant [2]. *** Industry Chain Supply - Demand and Inventory Change Analysis - Supply Side: The overall ethylene glycol operating rate remained stable at 67.63%, with the oil - based operating rate at 76.23% and the coal - based operating rate at 54.29% However, the profit structure was divided The oil - based profit (such as ethylene oxidation method) generally deteriorated, for example, the profit of ethylene - SHELL oxidation method decreased from - 799 yuan/ton to - 889 yuan/ton, a decrease of 90 yuan, indicating rising crude oil cost pressure The coal - based profit improved from 112.46 yuan/ton to 187.07 yuan/ton, an increase of 75 yuan, indicating that the decrease in coal cost supported coal - based production capacity [2]. - Demand Side: The load of downstream polyester factories remained stable at 89.42%, and the load of Jiangsu and Zhejiang looms remained at 63.43%, showing no change, reflecting stable terminal demand without significant improvement or deterioration The high load of the polyester sector supported ethylene glycol consumption, but the low loom load indicated weak terminal textile demand [3]. - Inventory Side: The inventory at the main ports in East China increased from 661,000 tons to 732,000 tons, an increase of 71,000 tons or 10.74% The inventory in Zhangjiagang increased from 215,000 tons to 275,000 tons, an increase of 60,000 tons or 27.91%, indicating obvious inventory accumulation, increased port arrivals or insufficient shipments, and increased inventory pressure [3]. *** Price Trend Judgment: The ethylene glycol price is expected to maintain a volatile pattern, with the upside limited by inventory pressure and the deterioration of oil - based profits On the supply side, the operating rate is stable but the profit is divided, with rising crude oil costs suppressing oil - based production capacity and falling coal costs benefiting coal - based production On the demand side, the high load of polyester provides support, but the low loom load and continuous inventory accumulation highlight the pressure of loose supply - demand The arrival of foreign goods is not mentioned to have changed, but the inventory increase implies potential import pressure Overall, the short - term rise of futures is driven by active trading, but the high inventory and stable demand in the fundamentals will limit the upside space, and the price may fluctuate in the bottom range [3].
