The US cotton good-to-excellent (G/E) rate dropped to 44% in mid-July, down 2 percentage points from the previous week and 10 points lower than a year ago. This marks the lowest level for this growing season and significantly underperforms the five-year average. Despite USDA's upward revision of the 2026/27 crop to 13.7 million bales, the deteriorating quality data raises doubts about the actual volume of high-grade cotton available for delivery.
Weather Premium vs. Production Upgrade
The persistent heatwave across Texas and the Southern Plains poses the greatest threat to current cotton development. This region accounts for a substantial share of US output, and July is the critical boll-filling stage where heat stress directly impacts yield and fiber quality. Although USDA raised the 2026/27 production estimate by 400,000 bales in its July WASDE report, that projection was based on end-June acreage and trend yields, not yet reflecting the July heat. Historically, every 5-point drop in the G/E rate leads to a 2-3% final yield revision. If the current weather pattern persists, the August supply-demand report may see a production cut. This means short-term markets will be dominated by a 'weather premium' rather than pure balance sheet numbers.
Oil Price Shock Reshapes Substitute Cost Curve
The renewed escalation of Middle East geopolitical tensions pushed oil prices up over 9% early this week, hitting a one-month high. Higher oil raises the production cost of polyester fiber, as PTA and MEG feedstocks are closely linked to naphtha and PX prices. For textile mills, a narrowing cotton-polyester spread will encourage some blends to increase the cotton ratio, providing indirect demand support for cotton. Notably, ICE December cotton futures held support at 81.51 cents/lb, and the market did not panic-sell despite the production upgrade. This is largely due to the substitution effect from surging oil. However, a strengthening dollar simultaneously pressures dollar-denominated cotton exports. The net effect likely keeps cotton in an 80-84 cent range.
Inventory and Procurement Rhythm
As of July 10, ICE deliverable stocks fell to 127,127 bales, a sharp drop of about 31,000 bales from the previous week. This suggests that some warehouse receipts are being absorbed—reflecting market acceptance of the current price range and also indicating tightening liquidity for high-grade cotton. For major importers like China, Vietnam, and Bangladesh, current prices are near some mills' psychological buying levels. However, with 2-3 months until new crop arrival and uncertainty over other Northern Hemisphere producers (India, Pakistan), downstream buyers prefer phased position-building rather than concentrated restocking.
