Crude oil has fallen back to pre-Mideast-crisis levels, yet polyester filament yarn remains nearly 1,000 yuan per ton above those levels. This price gap is not driven by cost or demand but by a strategic standoff between upstream producers and downstream weavers in a weak market.
Crude Collapse vs. Polyester Stubbornness
On June 24, 2026, WTI crude briefly broke below $70/barrel and has since hovered near that level, erasing all the geopolitical risk premium accumulated since the Middle East tensions escalated. However, polyester filament yarn prices have not followed suit. Industry data shows current prices remain about 1,000 yuan/ton above pre-crisis levels.
PTA and MEG futures have essentially returned to their starting points, implying that polyester filament now enjoys substantial theoretical cash margins. Yet this paper profit has not translated into actual price cuts.
The High-Inventory, Low-Operating-Rate Paradox
Polyester plants face a dilemma. As of June 24, the operating rate for domestic direct-spun polyester filament stood at 73.81%, a three-year low. While low rates should help control inventory, reality tells a different story:
- POY inventory: ~30 days
- FDY inventory: ~35.7 days
- DTY inventory: ~41.8 days
These inventories were produced when raw material costs were high. Aggressive price cuts now would turn book losses into realized losses. Hence, plants prefer slow price declines and gradual sales over a one-time crash.
Weavers' 'Buy Only for Orders' Strategy
For downstream weaving mills, the high cash margin of polyester filament signals significant room for future price drops. Unless they have confirmed orders, purchasing raw materials for inventory risks a cost disadvantage of hundreds of yuan per ton within a month—for the same final product.
As a result, mills have adopted a "buy only for confirmed orders" stance, further suppressing transaction volumes and reinforcing the fragile equilibrium.
Diverging Domestic and Export Demand
The core issue is weak supply-demand balance. On the domestic front, summer sun-protection fabrics should be in peak season, but unusually cool weather has delayed demand. Near July, temperatures remain low, stalling the seasonal uptick.
Export markets offer a silver lining. With the Strait of Hormuz shipping channel fully reopened, global crude and commodity trade is recovering. Multiple overseas economies are accelerating, potentially boosting international textile demand. Export orders could partially offset domestic weakness and ease downward pressure on polyester filament.
Near-Term Outlook: Prolonged Standoff
In the short term, the weak supply-demand, high-margin gap pattern is likely to persist. The tug-of-war between upstream and downstream will dominate market direction. Polyester plants must balance high-cost inventory against cash flow pressure; weavers await a better buying window.
Three key indicators to watch: (1) whether crude stabilizes below $70, (2) the pace of polyester inventory digestion, and (3) actual export order fulfillment.
