On June 30, the polyester chain collectively turned positive after a deep correction, with PX closing up 0.87% and PTA up 0.91%. This rebound is not a simple oversold bounce but the result of three converging factors: the fading of geopolitical premiums, active supply contraction, and marginal improvement in downstream demand. For procurement teams and factories along the chain, understanding the driving logic behind this rebound is more critical than focusing on daily price movements.
Stripping Geopolitical Premiums and Restocking Expectations
The core driver behind the polyester chain's correction is the marginal improvement in navigation conditions in the Strait of Hormuz. Latest data shows that shipping volumes have recovered to about 75% of pre-conflict levels. Although shipping insurance rates remain high, the restoration of physical navigation capacity has significantly weakened market panic over supply disruptions. PX prices have even broken below pre-conflict levels, reflecting the market's gradual stripping of the 'conflict premium' previously priced in.
Meanwhile, strategic reserves in various countries have fallen to low levels, theoretically creating strong restocking momentum. This means that once prices stabilize, potential demand release could become a catalyst for further PX and PTA price recovery. However, it is worth noting that whether restocking translates into actual purchases depends on downstream expectations of price trends.
PTA Supply: Historical Maintenance Opens a De-stocking Window
Since April, China's PTA industry has experienced an unprecedented wave of concentrated maintenance. The total capacity involved in shutdowns and reduced operations once exceeded 22 million tonnes, accounting for over 20% of the country's total capacity. PTA daily capacity utilization once fell to about 60%, the lowest level since October 2021. This active production cut has directly pushed the industry into a de-stocking phase, with social inventories continuing to decline.
The supply contraction provides a floor for PTA prices. However, with improved PX supply expectations (earlier maintenance PX units may restart ahead of schedule), cost-side support for PTA may weaken. This means that the height of PTA's rebound will depend more on whether downstream demand recovers simultaneously, rather than solely relying on supply tightening.
Downstream Demand: Signs of Recovery in the Off-Season
Looking at the downstream polyester segment, overall industry profits are currently acceptable. Except for polyester chips and polyester filament yarn DTY, other products have a profit margin of 200-300 yuan per tonne, providing a basis for factories to maintain operations. As of June 18, the average operating load in China's polyester industry was 80.19%, down 8.44 percentage points year-on-year, corresponding to a weekly PTA demand of about 1.34 million tonnes.
More noteworthy is the terminal weaving sector. Although it is currently the traditional consumption off-season, recent orders have shown signs of recovery. The weaving industry operating load is 57%, down 13 percentage points year-on-year, but the recovery in orders suggests the off-season may not last long. However, polyester filament yarn inventories are still climbing, indicating that terminal purchasing willingness has not fully recovered. The market remains in a state of 'tightening upstream, compressing midstream, and weak repair downstream.'
Sustainability of the Rebound: Three Key Variables
In the short term, the polyester chain's rebound has some fundamental support. Active de-stocking on the supply side, the release of geopolitical premiums, and potential restocking demand together form the basis for price repair. However, whether the rebound evolves into a trend depends on three variables:
- The full restoration progress of navigation in the Strait of Hormuz and the pace of decline in shipping insurance premiums;
- The restart pace of PTA maintenance units; if restarts are too fast, they may suppress prices again;
- Whether the recovery in terminal orders can be sustained and translated into actual increases in weaving operating rates.
