Supply Contraction and Cost Support Dual Drivers: PTA Market Prices in China Show Fluctuating Uptrend in August

ECHEMI 2026-09-01

August 31 news

Commodity market analysis system, in August, the PTA market in China showed an overall upward trend. At the beginning of the month, the price in the East China region was 5945 CNY/ton, and by the end of the month, it had risen to 6303 CNY/ton, a price increase of 6.02%. In August, the PTA market in China experienced a structural uptrend. The core driver of this round of price increases was a significant reduction in supply, coupled with cost support from geopolitical disruptions in the oil market. Meanwhile, terminal demand remained relatively weak, making this a typical supply-driven market trend rather than one driven by a substantial recovery in end-user consumption.

The market as a whole showed clear, stage-specific differentiation. In early August, the PTA market generally fluctuated within a narrow range. Downstream textile end-users continued to face weak demand typical of the off-season, resulting in insufficient overall market demand. Polyester plants mostly focused on replenishing stocks based on immediate needs, with no significant concentrated restocking activities. As a result, trading sentiment remained subdued, and price fluctuations were limited. However, by mid-August, market dynamics completely reversed. Several major, large-scale PTA production units in China entered a period of concentrated maintenance, causing the industry’s operating rate to rapidly decline to around the year’s lowest level of 63%. The supply of spot goods tightened significantly, corporate inventories continued to be depleted, and social inventories fell to low levels, highlighting a tight spot market situation. Meanwhile, international crude oil prices remained volatile and tended to strengthen amid geopolitical tensions, driving up upstream PX feedstock prices simultaneously. Under the combined effect of these two positive factors, PTA prices began a sharp upward trend, with monthly price increases becoming markedly significant.

Looking ahead, the PTA market in September is likely to see intensified bullish-bearish competition, and prices may shift from a unidirectional upward trend to high-level fluctuations. Pressure on the supply side is gradually becoming more apparent: from late August to early September, several major units that had undergone maintenance earlier began restarting operations one after another, causing the industry’s operating rate to rebound rapidly. The tight spot-market situation that has persisted for nearly a month is gradually easing, and the increased supply entering the market will directly limit further room for PTA prices to rise.

Cost-side support is weakening marginally at the same time. International crude oil prices are experiencing sharp fluctuations due to geopolitical disruptions, leading to heightened market uncertainty. Meanwhile, PX units undergoing maintenance are gradually resuming production, easing supply-demand conditions on the feedstock side and thereby weakening cost support for PTA. Going forward, PTA prices will likely follow the volatile pulses in crude oil prices more closely.

Demand remains the key variable in the market, as it officially enters the traditional "Golden September" consumption peak season. However, there is significant uncertainty about the recovery of terminal textile orders. Additionally, the polyester industry's profits are being squeezed by MEG prices, putting pressure on production profits for enterprises, and there is a risk that polyester operating rates may decline.
