Market Analysis Highlights on 21st

1. Cost Side: Weakening Support (Primary Factor)

International crude oil and PTA prices have continued to trend downward recently.

With raw material costs declining, profit margins for filament manufacturers have narrowed, forcing them to lower their quoted prices accordingly.

2. Demand Side: Continued Weakness; Strong Wait-and-See Sentiment

Downstream weaving mills face a shortage of orders, leading to a decline in operating rates and resistance to high-priced polyester filament.

On the 21st, the market's production-to-sales ratio remained low (approximately 40–60%), with transactions driven primarily by small-volume orders covering immediate necessities.

Raw material inventories at weaving enterprises remain at low levels; however, due to a bearish outlook on future market trends, they are hesitant to undertake large-scale restocking.

3. Supply Side: Increased Maintenance Limits Downside

Planned maintenance capacity increased at the end of April (by approximately 900,000 tons/year), resulting in a slight decline in operating rates.

Industry inventory levels remain moderate; consequently, the potential for a sharp decline is limited, with the market expected to be characterized primarily by gradual, creeping declines and narrow-range adjustments.

4. Market Sentiment

Manufacturers: Focused primarily on shipping goods and securing payments, with some offering price concessions to boost sales.

Downstream Buyers: Adopting a "buy on the rise, hold off on the decline" strategy; they continue to observe the market from the sidelines, awaiting lower prices.

Short-Term Outlook (Late April – Early May)

Trend: Weak-biased volatility and a narrow, gradual decline; a sharp drop is unlikely, and a sharp rally is even less probable.

Key Observations:

Have Crude Oil and PTA halted their decline and stabilized?

Are downstream textile manufacturers engaging in concentrated inventory replenishment?
