What Is COMEX?
COMEX (Commodity Exchange) is a division of the CME Group and the world's primary futures exchange for precious and base metals. It operates approved warehouses across the United States where physical gold, silver, and copper are stored. These warehouse stocks back the futures contracts traded on the exchange and provide transparency into the physical supply available for delivery. COMEX inventory data is released daily and is closely watched by traders, analysts, and investors worldwide.
Why Warehouse Inventory Matters
COMEX warehouse inventory is one of the most important indicators of physical metal supply in Western markets. When inventory levels decline, it suggests that physical demand is outpacing supply being delivered to warehouses. Persistent drawdowns can signal a tightening market that may eventually push prices higher. Conversely, rising inventory indicates comfortable supply conditions. The ratio of registered to eligible metal is also significant because it shows how much inventory is immediately available for futures contract delivery.
Registered vs Eligible Inventory
COMEX inventory is split into two categories. Registered metal has an active warrant attached and is available for delivery against futures contracts. Eligible metal meets the exchange's standards for purity and weight but has not been warranted for delivery. Metal can move between these categories: owners register eligible metal when they want to make it deliverable, or they can remove warrants from registered metal to take it off the delivery pool. Watching the flow between categories provides insight into market participants' intentions.
Frequently Asked Questions
- What is COMEX warehouse inventory?
- COMEX warehouse inventory is the total amount of physical metal stored in CME Group-approved depositories across the United States. These stocks back futures contracts and are reported daily, broken into registered (available for delivery) and eligible (meets standards but not yet earmarked) categories.
- Why do traders watch COMEX inventory levels?
- Declining COMEX inventory can signal tightening physical supply, which may put upward pressure on prices. Rising inventory suggests comfortable supply. Large, sudden drawdowns often indicate strong physical demand that futures markets may not yet reflect.
- What is the difference between registered and eligible inventory?
- Registered inventory has been assigned a warrant and is available for delivery against futures contracts. Eligible inventory meets exchange purity and weight standards but has not been registered for delivery. Metal can move between categories as owners decide whether to make it deliverable.
- How often does COMEX update inventory data?
- COMEX publishes warehouse stock reports daily, typically after market close. Reports include per-depository breakdowns showing registered and eligible stocks, previous day values, and net changes for each approved vault operator.
- Who stores metal in COMEX warehouses?
- COMEX-approved depositories include major vault operators such as JP Morgan Chase, Brink's, HSBC, Malca-Amit, and others. These facilities are located across the United States and must meet strict CME Group standards for security, insurance, and reporting.
