Crude Oil and Polyester Feedstock Surge Boost Polyester Filament Yarn Sales by 60 Percentage Points

The linked rally in crude oil and polyester feedstock prices injected a strong stimulus into the polyester filament yarn market on July 8. Industry public data shows that the average sales-to-production ratio of sample polyester filament yarn enterprises surged by 60.7 percentage points to 103.6%. This means that not all production was sold, but some inventory was also cleared. This dramatic fluctuation refocuses the industry's attention on the interplay between cost transmission and demand resilience.

Event Background

On July 8, international crude oil prices strengthened, driving up prices of polyester feedstock PTA and MEG simultaneously. This sudden cost pressure quickly transmitted to the downstream polyester filament yarn market. Polyester factories took the opportunity to raise quotes, while weaving mills, which had been waiting on the sidelines, rushed to restock driven by the 'buy on rising, not falling' psychology. This concentrated procurement directly boosted the day's sales-to-production ratio.

However, the market was not uniformly strong. The specific sales data for individual enterprises showed extreme divergence: the highest reached 300%, while the lowest was only 10%. This polarization indicates that downstream purchases were not based on optimistic judgments of end demand, but on a stress response to raw material price increases. Large factories with brand and channel advantages quickly cleared inventory, while small and medium-sized enterprises saw limited order growth due to weaker bargaining power.

Industry Impact

The jump in the sales-to-production ratio temporarily alleviated inventory pressure for polyester factories, but its transmission effect on the entire chemical fiber industry chain needs calm assessment. From the upstream perspective, if raw material price increases persist, they will compress processing margins for polyester factories; if downstream demand fails to follow, the price hike may be a 'false fire.' From the downstream perspective, the restocking behavior of weaving mills is more tactical than strategic. The current terminal apparel and home textile markets show no clear signs of recovery, casting doubt on the sustainability of restocking.

For weaving industry clusters in Jiangsu and Zhejiang (such as Shaoxing, Xiaoshan, Wujiang), this sales pulse may support operating rates for about a week. However, if subsequent orders fail to materialize, factories will again face the risk of finished product inventory buildup. Notably, individual cases with a ratio as high as 300% may involve large order deliveries or speculative stockpiling by traders, and do not represent the market norm.

Practical Recommendations

For Buyers - Monitor crude oil price trends and polyester feedstock cost curves. Lock in procurement prices during short-term pullbacks to avoid concentrated chasing during price rallies. - Establish dynamic inventory management mechanisms, extending safety stock cycles from 7 days to 10-14 days to cope with cost-driven price volatility. - Prioritize cooperation with suppliers maintaining a stable sales-to-production ratio above 80%, as such companies typically have stronger cost control and delivery assurance.

For Foreign Trade Enterprises - Beware of the transmission of short-term pulses in the domestic market to export quotations. Rapid domestic price increases may trigger overseas customer price pressure or order diversion. - Utilize the current relatively stable raw material price window to sign short-term (1-2 month) fixed-price contracts with overseas clients to hedge against subsequent cost volatility. - Monitor polyester filament yarn price linkages in emerging markets like Southeast Asia and South Asia to assess potential arbitrage opportunities or intensified competition.
