The ongoing heatwave in Texas, the largest cotton-producing state in the US, is eroding crop quality faster than expected. As of the week ending July 12, the US cotton good-to-excellent rating dropped to 44%, down 2 percentage points from the previous week and a sharp 10 percentage points below the same period last year—the lowest level since 2021. For Chinese mills that rely heavily on US cotton as a core blend component, this signals growing uncertainty in long-term procurement costs.
The Paradox of Weather Premium and Higher Output
The market's most critical contradiction lies in short-term weather threats lifting prices versus USDA's July WASDE report, which raised the 2026/27 US cotton output estimate by 400,000 bales to 13.7 million bales, with global supply also up by 300,000 bales. USDA seems to believe that expanded acreage and yield potential can offset some heat damage. However, field conditions tell a different story. The Southern Plains, particularly West Texas—the nation's most vital cotton belt—are enduring persistent extreme heat. A Price Futures Group vice president noted that hot weather provided the main support for the day's cotton prices. The ICE December contract settled at 81.51 cents/lb, down merely 0.03 cents, indicating the market still prices in significant weather risk. For traders and mills, this contradiction widens the price range: if rain comes, premiums could quickly evaporate; if heat persists into the critical boll-setting period in August, ratings may fall below 40%, triggering a downward revision in output expectations.
Oil Price Surge: An Unlikely Ally for Cotton
Another variable comes from the energy market. Escalating US-Iran maritime blockades raised concerns over Strait of Hormuz traffic, sending oil prices up 9% on July 13—a one-month high. Surging oil directly raises polyester production costs, indirectly boosting cotton's relative competitiveness. In the short term, this logic holds: when chemical fiber costs spike, some mills may temporarily increase cotton blending. However, oil volatility is notoriously sharp and unsustainable. Once geopolitical premiums fade, polyester prices will fall back, pressuring cotton again. Additionally, higher oil raises both sea and land freight costs, creating a hidden headwind for textile exports, especially for Chinese gray fabric and garment exporters targeting Southeast Asia and the Middle East.
Strong Dollar and Inventory Drawdown
On the macro front, the US dollar index edged higher, weighing on dollar-denominated cotton. While analysts argue the rise was modest and not decisive, a strengthening trend will dampen overseas buying interest. China, the world's largest cotton importer, faces higher import costs if the yuan continues to weaken against the dollar, potentially slowing port transactions. On the inventory side, ICE deliverable cotton stocks fell from 158,607 bales to 127,127 bales, a weekly decline of over 20%. Rapid destocking often signals increased spot activity or delivery demand, providing psychological support for bulls at lower price levels. However, current inventory remains above last year's levels, so absolute volume is not yet tight.
