The CFTC also publishes a report showing the quantity of cotton that has been bought or sold where the sales price has not been fixed would normally be on in a basis type contract, which are also referred to as “on call” contracts. Textile mills routinely buy cotton from merchants using “on call” contracts. When these parties enter in to the “on call” contract, a futures contract would normally be sold to hedge the transaction. Later, when the mill actually fixes the price, that short futures position would be bought back. This could be done with options or futures. To the extent that mills don’t independently cover their options positions, their un-priced “on call” contracts are reflected in the current “on call” sales report, under “Unfixed Call Sales”, which is reported by individual futures contract. When the unfixed call sales (to mills) outweighs the unfixed call purchases (by suppliers) the implication is that there will potentially be a lot of futures buying as mills hit the deadline of their “on call” contracts, fix the price, and the associated short hedges are bought back. We have seen this before in the last few years, e.g., most notably during June of 2013. There was a lot of thinking that on call buying would support or lift cotton prices during 2014, but the historically large discrepancy between unfixed call sales and purchases appeared to resolve itself without explosive rallies. Perhaps this was because the reported sales were not true biz to biz sales, e.g., they were consignment sales within big merchant shippers.
For what it is worth, as of June 16, 2017, the old crop Jul’17 contract discrepancy had shrunk to four unfixed call sales for every unfixed call purchase. There is also little open interest left in the Jul’17 (only 2.4% of the total), so the potential for fireworks is past.
