The summer cocoon purchase price in Qianjiang, Chongqing, has settled at around 51 CNY per kilogram, a level that sits in the mid-to-upper range of the past five years. More notable than the price itself is the fact that the district has maintained the top cocoon output in Chongqing for 15 consecutive years, with the sericulture industry covering all 24 townships. This indicates that Qianjiang is no longer a scattered sideline production area, but a regional industrial belt with stable output capacity.
Supply and Price Dynamics
The summer cocoon harvest has directly led to a looser supply outlook. By industry convention, summer cocoons account for about 20% of annual output. A bumper harvest in Qianjiang means a significant increase in spot supply in Chongqing and surrounding markets in the short term. For buyers, this expands bargaining room; for cocoon stations and silk reeling mills, raw material procurement costs are expected to decline slightly. However, the purchase price has not fallen sharply, suggesting that quality or order structure is providing some support despite the abundant supply.
Along the value chain, easing cocoon prices gradually affect raw silk costs. Raw material costs typically account for over 60% of raw silk pricing. A fluctuation of 1 CNY per kilogram in cocoons corresponds to a change of about 40 CNY per ton in raw silk costs. The current abundance is weakening cost support for raw silk, creating a mild bearish factor. However, this transmission has a time lag of two to four weeks, so downstream enterprises need to adjust procurement timing accordingly.
Scale Effects of the Regional Industrial Belt
Qianjiang's sericulture industry spans 24 townships, indicating a complete chain from mulberry planting, silkworm rearing, to harvesting and drying. Maintaining the top output in Chongqing for 15 years reflects long-term accumulation in breed improvement, technical extension, and infrastructure investment, not just a one-off bumper year. For buyers, such a stable production area means more predictable supply cycles and better quality consistency.
But scale also brings new challenges: when regional output remains high, local processing capacity may be insufficient, increasing pressure to sell outside the region. In addition to meeting local reeling demand, some Qianjiang cocoons must flow to major consumption areas like Guangxi and Zhejiang. Logistics costs and cross-regional price differentials will become important factors in procurement decisions. According to industry public data, road transport from Chongqing to Zhejiang costs about 350 to 450 CNY per ton, which can shift sourcing choices when cocoon prices fluctuate.
Market Outlook and Operational Strategies
Based on supply and demand fundamentals, cocoon and silk prices are likely to remain weak and volatile in the short term. The summer harvest, combined with the expected autumn cocoon supply (typically around mid-September), will keep supply ample for the next two months. However, the risk of extreme weather or pests affecting autumn output should not be ignored; any production shortfall could trigger a rapid price rebound. Therefore, it is advisable for all parties to adopt a phased procurement strategy and avoid concentrated stockpiling or liquidation.
