On the night of August 4, the polyester chain experienced a rare price earthquake: the ethylene glycol (EG) main contract plunged 6% to 4,631 yuan/ton, while PTA, staple fiber, bottle chip, and paraxylene futures fell about 2% each. This is not an isolated fluctuation but a resonance of easing feedstock costs and loose supply-demand fundamentals, which will have a direct and profound impact on the procurement rhythm and inventory strategies of downstream textile enterprises.
Event Background
After the night session opened, the domestic futures market showed more declines than gains, with EG leading the drop, falling over 3% by 21:02 and expanding to 6% within just over an hour to 4,631 yuan/ton. Meanwhile, PTA fell 2% to 5,786 yuan/ton, staple fiber dropped 2% to 7,280 yuan/ton, paraxylene declined to 8,054 yuan/ton, and bottle chip futures also fell over 2%. The linked declines across varieties indicate a collective lack of confidence in the cost support of the polyester chain.
The sharp drop in EG is not without clues. As one of the two main raw materials for polyester production, EG pricing has long been influenced by crude oil prices and its own supply-demand dynamics. The sharp night-session decline likely reflects a combination of weakening international oil prices, high port inventories, and sluggish downstream demand. Notably, EG futures have broken below the 4,700 yuan/ton mark, hitting a recent low, signaling that the market is reassessing the logic of cost support.
Industrial Impact
For polyester plants, the sharp drop in raw material prices implies a passive expansion of theoretical processing margins, but actual procurement decisions will become cautious. Because rapid declines in futures prices are often accompanied by a wait-and-see attitude in the spot market, plants tend to consume high-priced inventories rather than rush to restock. This 'buy on rising, not on falling' mentality may lead to subdued spot trading in the short term, further capping price rebound.
For downstream weaving and dyeing enterprises, this is a signal worth watching. Raw material costs typically account for over 60% of fabric costs. Declines in EG and PTA will gradually transmit to intermediate products such as polyester filament and staple fiber, ultimately lowering the cost base of greige goods and fabrics. For buyers with bargaining power, this may be a window to lock in low-cost raw materials and optimize cost structures. However, caution is needed: if international oil prices rebound or supply-side disruptions occur, prices could quickly recover, and the opportunity may be missed.
From a regional industrial belt perspective, textile clusters such as Shengze, Changle, and Keqiao are highly sensitive to polyester raw material prices. This EG plunge will temporarily ease cost pressures for small and medium-sized weaving enterprises in these areas, but if prices continue to fall, it may also trigger customer expectations of lower product prices, squeezing fabric makers' margins. Therefore, all links in the chain need to reassess inventory levels and pricing strategies.
Practical Recommendations
For Buyers - Closely monitor night-session trends of EG and PTA futures. If prices stabilize around 4,600 yuan/ton, consider signing forward raw material contracts in batches to lock in costs. - Negotiate with polyester plants to adopt a 'futures point pricing' model, linking purchase prices to the board, avoiding additional costs from lagging spot quotes. - Appropriately extend raw material inventory cycles to 15-20 days, but set stop-loss lines to prevent inventory write-downs if prices continue to fall.
For Foreign Trade Enterprises - Reserve a 3-5% price adjustment clause in quotations to hedge against profit erosion from raw material cost fluctuations. - Utilize forward exchange settlement and raw material futures hedging tools to hedge against both exchange rate and cost risks, especially for long-term contracts. - Monitor overseas suppliers' dynamics. If domestic price advantages expand, moderately increase export order intake, but assess logistics and tariff costs.
This night-session plunge is essentially a market vote on the rebalancing of the polyester chain's supply and demand. In the short term, weakening cost support will cap the price center; in the long run, if downstream demand recovers, low-cost raw materials may instead stimulate restocking demand, forming a new balance. Textile enterprises should remain rational and seek certainty amidst volatility.
