Cotton futures edged higher on July 15, with the ICE December contract settling at 81.55 cents per pound, up 0.68 cents or 0.84% from the previous session. The rally was driven by two external market variables: a strong performance in grain markets and a simultaneous weakening of the US dollar.
External Market Linkage
Chicago Board of Trade wheat futures surged over 5%, and European wheat prices hit a one-year high, mainly due to escalating attacks on shipping lanes in the Azov Sea—a key export channel for Russian wheat. Supply concerns in grains quickly spilled over into cotton, creating price momentum. Meanwhile, the US Bureau of Labor Statistics reported that June Producer Price Index (PPI) fell 0.3% month-on-month, significantly below market expectations of flat growth, while May data was also revised lower. The cooling inflation signal reinforced expectations that the Federal Reserve could maintain patience on interest rates. The US dollar index dropped 0.55% to 100.36, its lowest since mid-June. A weaker dollar makes dollar-denominated cotton more affordable for overseas buyers, directly supporting futures prices.
Weather Uncertainty Becomes Core Mid-Term Factor
Despite short-term external support, the industry's real concern has shifted to weather conditions in major growing regions. Currently, key US cotton belts are not experiencing drought, and crop development in the first half of the growing season has been satisfactory. However, climatic conditions in the second half will directly determine final yields. The USDA's daily weather report noted persistent high temperatures in southeastern Montana and most of the Dakotas in the Great Plains, with uncertain impacts on small grains during their heading stage. Although cotton's growth phase differs slightly, the potential stress from high temperatures on boll development cannot be ignored. Historically, late July through August is the critical window for cotton yield formation, and any extreme weather event could significantly alter supply-demand balances.
Cost Dynamics and Substitution Logic
Another supportive factor is crude oil prices. Fresh US strikes on Iranian military facilities have escalated geopolitical tensions in the Middle East, sustaining oil price gains. Higher oil prices raise production costs for polyester fiber, thereby maintaining cotton's price competitiveness relative to synthetics. For downstream textile mills, this means cotton's substitution effect is unlikely to be undermined by cheaper man-made fibers in the near term.
Inventory and Positioning Signals
As of July 14, ICE-certified cotton stocks stood at 100,612 bales, down from 121,285 bales the previous day. The decline in inventories generally reflects reduced deliverable supply or accelerated warrant cancellations, providing underlying support to futures prices. With prices hovering above 80 cents per pound, the market is witnessing intensified long-short positioning.
