Night session price divergences often foreshadow real contradictions within the supply chain. Data from the domestic futures night session on May 13 sends a clear signal: cotton and cotton yarn posted modest gains, while staple fiber, PTA, and bottle-grade chips all declined. Although the moves are small, the directional consistency warrants attention—raw material and polyester processing segments are moving toward different pricing logics.
Cotton and Cotton Yarn: Resilience from Cost Support
Cotton's main 2609 contract settled at 16,580 points, up 0.64%, while cotton yarn's 2607 contract closed at 22,455 points, up 0.45%. In absolute terms, cotton found solid support around the 16,500 level, closely tied to new-season planting costs, the inverted spread of imported cotton, and the linkage effect with ICE cotton futures abroad. Cotton yarn followed the uptrend but with a smaller gain, indicating limited capacity among downstream weaving mills to absorb higher-priced raw materials—spinners are more likely restocking passively than chasing prices actively.
This price structure implies that the current cotton rally is not demand-driven but rather cost- and supply-expectation-supported. For buyers, the 16,500-16,600 yuan/ton range serves as a critical cost anchor; without a sharp drop in external markets, a deep correction in domestic cotton is unlikely.
Polyester Chain: Double Hit from Inventory Pressure and Weak Demand
In stark contrast to cotton's mild strength, polyester-related contracts all weakened. Staple fiber 2607 fell 0.64% to 8,044 points, PTA 2609 dropped 0.53% to 6,374 points, and bottle-grade chips 2607 declined 1.27% to 8,246 points. The synchronized decline across three products—with bottle chips falling the most—points to a common pressure across the entire polyester chain rather than a single-issue problem.
The decline in staple fiber and PTA is primarily driven by two factors: first, polyester plant operating rates remain high, but terminal weaving and texturing mills have not seen the expected seasonal order surge, leading to continuous inventory buildup; second, upstream PX prices have recently softened, weakening cost support. Bottle chips fell the most, reflecting a dual pressure from declining export orders and the seasonal lull in domestic beverage packaging demand.
From an industry perspective, polyester margins are being squeezed from both ends: upstream PX prices, though weaker, remain above last year's levels, while downstream end-users resist high polyester product prices, leaving the intermediate segment with no choice but to cut prices to clear inventories. This 'pincer' pattern is unlikely to reverse in the near term.
Implications for Procurement Strategy from Cross-Product Spreads
The spread between cotton and staple fiber is widening. Cotton rising while staple fiber falling means the cost-effectiveness ratio in blended applications is shifting. For blended yarn producers, the relative price advantage of staple fiber is now more pronounced, and this may be reflected in subsequent raw material mix adjustments.
The divergence between PTA and cotton also signals subtle shifts in the competition between chemical and natural fibers. If cotton prices remain firm while polyester prices continue to weaken, some apparel brands may tilt their sourcing strategies toward chemical fiber products, potentially putting downward pressure on cotton's forward demand.
