Due to the late crop, a lot is riding on maturation/harvest period weather.
On the one hand, USDA's July revisions of 2018/19 world cotton supply continued a somewhat bearish projection of increasing U.S. ending stocks. The old crop adjustments showed a month-over-month 1.74 million-bale increase in world ending stocks. This change resulted from adjustments across a number of different countries. The bottom line of all this was a modest increase in world ending stocks, which would have mostly neutral implications for old crop world prices, but it does add more supply to the world new crop balance sheet.
The USDA’s July adjustments to the U.S. old crop cotton numbers saw a similar month-over-month cut in domestic use (-100,000 bales) and exports (-250,000 bales). These changes went straight to the bottom line of the U.S. old crop balance sheet. Both the monthly and year-over-year adjustment in ending stocks would be modestly bearish according to history and theory.
