U.S. Copper Inventories Hit All-Time High at Comex Warehouse

The CME Group is the authoritative source for COMEX copper inventory data, making its information decisive for this assessment. The official copper futures page provides verified inventory figures, establishing a reliable baseline for determining record levels. Bloomberg’s recent reporting corroborates these figures, explicitly stating that U.S. COMEX copper inventories reached an all-time high and citing CME data as the source. Additional CME documentation, such as warehouse notices and commodities updates, provides consistent background confirming larger-than-usual stock levels, though not always specifying exact record figures. No credible or authoritative source contradicts this claim. Considering the high authority of CME Group as the data originator and Bloomberg as a respected secondary verifier, the evidence strongly supports that COMEX copper inventories in the U.S. reached their highest level on record at the time in question.
