The closing date of reserve cotton sales often reveals more about the regulator's read on supply and demand than the opening date does. China Reserve Cotton Management Co. has confirmed that central reserve cotton sales for 2026 will end on September 30. That date lands precisely at the handover between hand-picked and machine-picked cotton in Xinjiang, signaling that policymakers believe new-crop supply can meet demand without further reserve releases to cap prices.
The Industrial Logic Behind the Timing
Over the past five years, reserve sales have typically concluded two to three weeks before new cotton hits the market. This year's September 30 cutoff covers pre-holiday restocking demand while avoiding direct price competition with new-crop purchasing. For ginners, it means a concentrated buying period begins after the National Day holiday, and the reserve's exit conveniently creates pricing room for seed cotton procurement.
For textile mills, the end of sales does not mean supply stops. Reserve cotton bought at earlier auctions remains in mill inventories, and imported cotton quotas at ports are still being digested. But structural differences matter: reserve cotton is predominantly mid-to-low grade, suited for rotor spinning and low-count yarns, while early new-crop arrivals are high-grade machine-picked cotton better suited for combed high-count yarns. The transition between these two原料 streams is not seamless. Mills producing low-to-mid count yarns may face a temporary tightening in mid-to-late October.
Regionally, mills in Shandong, Henan, and Jiangsu have historically relied more on reserve cotton than their Xinjiang counterparts. Xinjiang spinners sit close to the raw material source, with shorter procurement radius and lower logistics costs. Inland mills, by contrast, need to lock in new-crop supplies early or risk a double squeeze from tight road transport and rising procurement costs after the holiday.
Price Transmission and Market Expectations
The support that the sales halt provides to cotton prices is already visible in futures markets. The Zhengzhou cotton main contract has shown a near-strong, far-weak structure around the announcement, reflecting concerns about short-term supply tightening and expectations of price declines once new cotton arrives in volume. This term structure poses a practical question for mills: whether to lock in some forward costs on the board.
The main contradiction in the chain is the weak pass-through to yarn prices. Fabric mills and garment factories are working with short, small orders and have limited tolerance for yarn price increases. This means that even if spot cotton prices edge up on the sales halt, spinners will struggle to pass the full cost burden downstream. Margin compression will hit small and mid-sized spinners first, especially those without differentiated product lines that rely on volume in conventional varieties.
The supplementary role of imported cotton should not be overlooked. If the domestic-international price spread remains within a reasonable range, sliding-scale duty quotas and bonded cotton stocks can partially offset the supply contraction from the reserve exit. But if international prices rise on weather or macroeconomic factors, the cost advantage of imports will erode, and upward pressure on domestic prices will become more pronounced.
For buyers, the core question is not whether cotton prices will rise, but how much the downstream can absorb. Based on yarn inventory days, most spinning mills have raw material coverage through mid-October. The real procurement pressure window falls in late October to early November. That period also coincides with clearer signals on new-crop quality and output, so price volatility may increase.
