乙二醇日报：煤制复产与库存施压，乙二醇静待成本驱动-20250812

Industry Investment Rating - No investment rating provided in the report Core Viewpoints - Ethylene glycol may continue to trade in a narrow range in the short term, constrained by high inventory and coal chemical restarts above, and supported by cost margins below. The market expects the mid - term supply - demand contradiction to ease, but the rebound of near - term contracts is limited. It is recommended to focus on the impact of oil and coal price fluctuations on cost logic [1][2] Summary by Directory 1. Daily Market Summary - Prices and Spreads: The price of the ethylene glycol futures main contract rose by 35 yuan/ton to 4457 yuan/ton, and the spot price in East China also rose by 35 yuan/ton to 4490 yuan/ton.

The 1 - 5 spread widened slightly from - 45 yuan/ton to - 33 yuan/ton, and the far - month structure remained at a discount [1] - Position and Volume: The position of the main contract decreased by 5762 lots to 199,600 lots, while the trading volume increased by 13,300 lots to 94,000 lots, indicating increased short - term capital games and some short - sellers closing their positions [1] - Supply: The overall ethylene glycol operating rate increased by 0.98 percentage points to 63.28%, with the coal - based operating rate rising by 2.53 percentage points to 58.98%, and the oil - based operating rate remaining at a high of 66.15%.

Weak terminal orders led to mainly rigid demand procurement of polyester raw materials, and the demand side lacked upward drivers [1] - Inventory: The inventory at the main ports in East China increased by 58,500 tons to 485,700 tons in a single week, and the inventory in Zhangjiagang soared by 40.6% to 180,000 tons.
