Polyester Chain Deadlock: Filament Cuts Squeeze Upstream and Downstream, Who Blinks First

International oil prices have fallen back to pre-war levels following the US-Iran peace deal, with the Strait of Hormuz resuming navigation. This geopolitical shift has triggered a "cost collapse" in the polyester chain, but rather than benefiting all players, it has ignited a three-way battle over volume, price, and profit among upstream raw materials, midstream filament yarn, and downstream weaving mills.\n\n## The Paradox of Cost Collapse and Price Stalemate\n\nChinese customs data show that maintenance shutdowns for PX and PTA have expanded in July, further reducing operating rates. While upstream faces immediate supply constraints, the key issue lies in the medium term: after August, as Strait shipping recovers and refinery maintenance ends, raw material shortages may ease. This means the core contradiction is not on the supply side but on demand—whether polyester operating rates can rise to match future raw material supply.\n\nMidstream filament yarn producers have chosen a different strategy: actively cutting output to maintain high processing margins and refusing price cuts. Industry data show that filament yarn processing profits are at multi-year highs, with operating rates around 70%. The logic is clear: in past years, every raw material price drop triggered filament price cuts, squeezing margins to near zero. Now, producers prefer to sacrifice volume to protect profits.\n\n## Downstream Weaving's Loss Dilemma\n\nBefore the oil price crash, downstream weaving mills had long suffered from "flour being more expensive than bread"—high filament prices paired with stagnant order prices for texturing and weaving, leading to widespread losses on a buy-and-produce basis. After the cost collapse, downstream hoped for relief, but resilient filament prices have kept them on the edge of losses.\n\nFor downstream, without reasonable raw material costs, taking orders means losing money. Thus, mills are waiting for filament prices to "catch down" to a rational level before restocking. This "waiting for a price cut" mentality deepens the production-sales stalemate: filaments won't cut prices, downstream won't buy, sales can't pick up, and filament inventories won't clear.\n\n## Upstream Anxiety and Expectations\n\nUnlike downstream's passive wait, upstream raw material producers are more anxious. PX and PTA plants have cut runs through maintenance, temporarily improving destocking, but their long-term need is for filament producers to raise operating rates. Only higher filament runs can boost direct PTA demand, enabling upstream to accelerate destocking and balance future supply-demand tables.\n\nUpstream hopes filament producers will launch a major promotion—if production-sales volume spikes, filament inventory pressure eases, giving them confidence to raise runs, which would revive upstream destocking. But filament producers are reluctant to yield, fearing that a price cut would trigger deeper downstream waiting and undo their output-cut efforts.\n\n## The Logic of Filament Output Cuts\n\nFilament producers' core strategy is to build a "profit fortress" through output cuts. Industry calculations show that running at full capacity yields 100 yuan per ton, while running at 70% yields 500 yuan per ton—a clear economic case. More importantly, they recognize that price wars would trap the entire chain in a vicious cycle: raw materials fall, filaments fall, downstream waits, and no one wins.\n\nThis hardline stance creates a stalemate loop: filaments won't cut prices, downstream won't buy, sales stay low, inventories remain high, runs can't rise, and upstream can't sell. The three parties' demands are contradictory: upstream and downstream both want filaments to cut prices or raise runs, but filament producers' success would sacrifice both sides' interests.\n\n## Practical Recommendations\n\n### For Buyers\n- Current filament prices are high and resilient; advise waiting for inventory pressure to force periodic promotional releases.\n- Watch for the August raw material supply recovery point, when filament catch-down probability increases; consider phased buying at lower levels.\n- Avoid large stockpiling during the stalemate; prioritize existing inventory to reduce capital risk.\n\n### For Exporters\n- Export order quotes must account for raw material price volatility; recommend floating price clauses or short-term hedging with clients.\n- Monitor Middle East geopolitical developments; if oil stays low, filament cost support weakens, allowing export strategy adjustments.\n- Use the current chain stalemate to optimize supply chain and seek more competitive raw material suppliers.
