The sharp drop in oil prices, triggered by a US-Iran peace deal and the reopening of the Strait of Hormuz, has failed to bring relief to the polyester chain. Instead, it has intensified a three-way standoff: upstream PTA producers seek higher filament yarn output to clear inventory, downstream weavers wait for yarn price cuts, while filament yarn makers use output cuts to sustain high margins. This article analyzes the game logic, industry impact, and procurement strategies.
The 'Impossible Triangle' of the Polyester Chain
The most immediate contradiction is the unusual resilience of filament yarn prices despite the collapse in raw material costs. In July, oil prices fell sharply, and PX and PTA plants reduced loads due to maintenance. Yet filament yarn makers, by cutting output, have managed to maintain high processing margins.
Downstream weavers had long suffered from a situation where 'flour is more expensive than bread'—high yarn prices squeezed margins, and orders could not be raised. Now that raw material costs have dropped sharply, yarn prices have not followed suit. For weavers, this feels like 'the upstream eats meat, while the downstream can't even get soup.'
The 'Profit Moat' of Filament Yarn vs. The 'Wait-and-See' Bottom Line
Filament yarn makers have their own logic. In the past, every time raw material prices fell, they would cut prices to boost sales, only to see processing margins eroded. Now, they are using output cuts to build a 'profit moat': previously, running full capacity yielded a margin of 100 yuan per ton; now, running at 70% capacity yields 500 yuan per ton. In their view, cutting prices now would trigger even deeper wait-and-see sentiment downstream ('if it can fall today, it can fall tomorrow') and undo all the efforts of the output cuts.
Downstream weavers, however, have their own rationale. Without reasonable raw material costs, taking orders means losing money. They prefer to wait until yarn prices 'catch down' to a breakeven level before restocking. This creates a classic prisoner's dilemma: 'if you don't cut prices, I won't buy; if I don't buy, your inventory won't clear.'
Upstream Anxiety and the Breaking Point
The upstream PTA sector is equally anxious. In July, PX and PTA loads fell sharply due to maintenance, but from August onward, with the Strait of Hormuz reopening and refinery maintenance ending, the raw material shortage will ease. The key question is whether polyester capacity can ramp up to match the return of raw material supply.
The upstream's core demand is for filament yarn makers to increase operating rates. Only when yarn sales pick up can PTA demand recover, accelerating destocking and balancing the forward market. The most effective lever to boost yarn output is a big promotion—a price cut that triggers a surge in sales. The upstream is eagerly waiting for such a move to unclog the chain.
But filament yarn makers show no sign of yielding. They are determined to protect their hard-won profit base, fearing that any price cut would trigger deeper wait-and-see sentiment and undo the output cuts. This intransigence has created a stalemate: yarn makers won't cut prices, downstream won't buy, sales don't pick up, inventory doesn't clear, output can't be raised, and PTA doesn't sell.
Industry Impact of the Stalemate
This three-way standoff pressures each link in the short term:
- For filament yarn makers: Output cuts protect margins temporarily, but inventory pressure builds. If downstream demand stays weak, high inventory will eventually force price cuts, risking a 'catch-down' in processing margins.
- For downstream weavers: The wait-and-see approach has a cost. While yarn prices haven't fallen, raw material costs have dropped sharply. If orders can support it, partial restocking may be better than waiting completely.
- For upstream PTA makers: Without higher polyester output, the destocking effect from maintenance is limited. When supply returns in the future, if demand doesn't pick up, PTA may face new inventory pressure.
