Physical Inventory
Commodity stock records track the volume of exchange-approved metals held in registered storage facilities for the Commodity Exchange. Market participants monitor comex warehouse inventories to gauge the immediate availability of physical copper or gold for delivery. These figures distinguish between registered metal ready for warrant and eligible metal that meets grade requirements but remains uncommitted.
Stock Category
Eligible holdings represent material that sits in the vault but does not yet have a document of title issued for exchange delivery. Conversion occurs when an owner requests a warrant, moving the metal into the registered category. Registered stocks fluctuate as traders settle futures contracts through physical transfer.
Daily reports provide transparency regarding the total weight of metal stored at each approved location.
Price Signal
Low stock levels often indicate a tightening market where demand outstrips the pace of new arrivals. Rapid withdrawals from comex warehouse inventories can lead to backwardation, where spot prices trade higher than future delivery prices. Analysts compare these levels against historical averages to determine if a supply deficit is emerging.
Large movements in inventory usually precede shifts in hedging behavior among industrial consumers and producers. Physical delivery remains the final mechanism that anchors futures prices to the reality of the metal market.
