PTA prices are approaching the psychological threshold of polyester mills. Market data from June 29 shows the PTA benchmark price at 5,734 yuan per ton, down 8.38% from 6,258.75 yuan at the beginning of the month. What does this figure imply? It is now close to the one-year average of 5,353 yuan and sits at the median of the year's price range (4,363.25 yuan to 6,932.90 yuan).
The Downtrend Is Not Isolated
The decline in PTA is not a one-month anomaly. Over the past year, PTA prices have fluctuated widely, from a low of 4,363.25 yuan to a high of 6,932.90 yuan. The current price has fallen back to near the median of 5,648.08 yuan, down 1,198.9 yuan from the annual peak. The market has not seen the expected summer restocking rally, but instead continued weakness during what should be a peak demand season.
From a value chain perspective, PTA, as the core raw material for polyester production, directly reflects the supply-demand balance upstream and downstream. Upstream, PX capacity continues to expand, keeping feedstock supply ample. Downstream, while polyester mill operating rates have recovered, terminal textile and garment orders have not shown substantial growth. This 'pressure in the middle, slack on both ends' pattern has made PTA the victim of margin compression in the chain.
The Sword of Overcapacity Hangs
The core contradiction in the PTA market is that capacity growth far outstrips demand growth. In the past two years, new PTA capacity has been concentrated, pushing total domestic capacity above 80 million tons per year, while downstream polyester demand has grown only 3%-5%. Even at the current price of 5,734 yuan, some high-cost plants are only marginally profitable. If prices fall below 5,500 yuan, it could trigger voluntary production cuts across the industry.
For polyester mills, falling PTA prices should lower raw material costs, but in reality, terminal greige fabric and finished fabric prices have weakened in tandem. This has led buyers to adopt a 'buy as needed' strategy, avoiding inventory buildup. This destocking behavior has further intensified spot liquidity pressure on PTA, creating a negative cycle of 'the more it falls, the less people buy; the less they buy, the more it falls.'
Regional Industrial Clusters Feel the Ripple
The persistent low PTA prices have begun to trickle down to regional industrial clusters. In concentrated polyester production areas such as Xiaoshan, Shaoxing, and Shengze, some small and medium-sized polyester enterprises have started to adjust operating rates. Chip and polyester filament yarn prices have followed PTA downward, but downstream weaving mills are cautious in taking orders, shifting inventory pressure from polyester plants to intermediate links.
From the export side, exchange rate fluctuations combined with orders flowing back to Southeast Asia have eroded the competitiveness of domestic textile exporters. The profit space created by lower PTA costs has been offset by rising logistics, energy, and labor costs, ultimately failing to translate into real gains for downstream enterprises.
