(Bloomberg) — Spot copper prices are again trading at a steep premium to later-dated futures in New York, putting fresh pressure on holders of short positions after a historic squeeze last month.
The July-delivery Comex copper traded at a 7.4 cent-per-pound premium to the September contract, in a condition known as backwardation that typically signals a supply shortage. The spread traded in an unprecedented 29.25-cent backwardation last month, putting huge pressure on commodity traders and investors with short positions in the July contract.
