ICE cotton futures posted modest gains on July 15, with the most active December contract settling at 81.55 cents per pound, up 0.68 cents or 0.84% from the previous session. This move was not an isolated event but the result of multiple macro and industrial factors converging, with strong performance in grain markets and a weakening U.S. dollar serving as core drivers.
Macro Linkages: The Conduction Effects of Grains and the Dollar
Chicago Board of Trade (CBOT) wheat futures surged over 5% on the day, while European wheat prices hit a one-year high. The trigger was the escalation of shipping attacks in the Sea of Azov, a key export channel for Russian wheat. The strength in grain markets created a clear spillover effect on cotton through market sentiment and capital flows. As one industry analyst noted, cotton futures are currently following the overall rhythm of external markets to a large extent.
Meanwhile, the U.S. dollar index fell 0.55% on July 15 to close at 100.36, its lowest level since mid-June. The direct catalyst was the unexpected 0.3% month-on-month decline in the U.S. Producer Price Index (PPI) for June, which contrasted with market expectations of flat growth. This data reinforced signs of easing inflation, further supporting market expectations that the Federal Reserve could maintain patience on interest rates. A weaker dollar makes dollar-denominated cotton more affordable for overseas buyers, providing support on the demand side.
Geopolitical Risks and Cost Transmission
Oil prices extended gains on the day, driven by the latest U.S. strikes on Iranian military facilities aimed at weakening Tehran's ability to attack commercial vessels in the Strait of Hormuz. Geopolitical tensions pushed crude prices higher, directly increasing the production cost of polyester, a substitute for cotton. This cost transmission effect gives cotton a relative price competitiveness advantage, serving as another supporting factor for cotton prices.
Weather Variables and Supply-Side Uncertainty
Another focus of current market attention is the weather conditions in major U.S. cotton-producing regions. Although the USDA's daily weather report noted persistent high temperatures in southeastern Montana and most of the Dakotas, which could affect the growth of barley and spring wheat, the specific impact on cotton-producing areas remains to be assessed. One brokerage president stated that while there are weather-related concerns, no drought conditions have emerged so far. Crop growth in the first half of the season has been satisfactory, but climatic conditions in the second half will directly determine final yields. It is difficult to predict output at this stage, so current cotton prices are in a relatively reasonable range.
Inventory and Spot Market Dynamics
In terms of inventory data, as of July 14, ICE deliverable stocks for No. 2 cotton futures stood at 100,612 bales, a significant decline from 121,285 bales in the previous session. This decrease in stocks partly reflects expectations of tightening supply. However, on the spot market, the Cotlook A index fell 75 points to 89.95 cents per pound on July 15, indicating a certain divergence between spot and futures markets. This could be a signal of weak downstream purchasing appetite.
