The September window for tussah cocoon arrivals is injecting a fresh supply variable into the raw silk market. With rising supply expectations and a clear divergence between domestic and foreign trade in water-reeled silk transactions, spot prices have softened. This combination suggests that the pricing balance has shifted in favor of buyers in the short term, and the Q4 outlook remains far from optimistic.
Supply Side: New Cocoon Volumes Reshape Price Anchors
According to the industry's production cycle, tussah cocoons enter a concentrated marketing phase every September, with raw material supply rising week by week. Compared with spring cocoons, autumn cocoons typically differ in reelability and cocoon shell ratio, but this year's arrival rhythm has largely followed historical patterns, with no significant climate-related delays. The certainty of supply increases has made processing links more cautious about stockpiling, with some silk reeling mills opting for on-demand purchases rather than bulk accumulation.
This sentiment is directly reflected in spot pricing. Raw silk prices lack upward momentum and have shown slight declines after the weakening of raw material cost support. For weaving enterprises that rely on stable raw material costs, the current price drop should be a positive, but weak downstream demand has offset this dividend, leaving midstream profit margins largely unchanged.
Demand Side: Trade Divergence Reflects Structural Issues
This month, domestic and foreign trade transactions of water-reeled silk have diverged, with foreign orders relatively stable and domestic demand clearly weakening. The resilience in foreign trade mainly comes from previously signed long-term agreements and restocking demand from some emerging markets, but new orders are limited, with most activity focused on executing existing contracts. On the domestic front, downstream home textile and apparel enterprises have slowed their stocking pace, and weak terminal consumer confidence directly suppresses enthusiasm for upstream raw material purchases.
This divergence is not a short-term fluctuation but reflects fundamental differences in demand momentum between domestic and international markets. Foreign trade benefits from RMB exchange rate movements and tariff policy adjustments in some countries, providing short-term support; domestic demand, however, is constrained by the post-real-estate cycle and sluggish consumer willingness, with a slow recovery. For raw silk suppliers, this means they cannot simply rely on export markets to absorb domestic demand gaps; product mixes and customer portfolios require more refined adjustments.
Price Outlook: Downward Pressure May Extend into Q4
Considering both supply and demand factors, raw silk prices are likely to maintain a weak and volatile pattern in Q4. On the supply side, tussah cocoon arrivals will continue until late October, with the peak in raw material supply yet to pass. On the demand side, the divergence between domestic and foreign trade is unlikely to reverse in the short term, and domestic recovery still requires policy stimulus transmission. Under the balance of bullish and bearish forces, bears hold a slight advantage, and the price center may shift further downward.
However, the downside space is not unlimited. The acquisition cost of tussah cocoons provides rigid support; if cocoon prices fall too much, farmers may hold back sales, which could in turn force reeling mills to raise prices to secure supply. Additionally, concentrated delivery of some foreign trade orders before year-end may cause periodic demand pulses. Therefore, the market is more likely to experience a pattern of "slow declines interspersed with intermittent stabilization" rather than a one-way plunge.
