September’s COMEX silver futures contract hit First Notice Day this week with a data point that precious metals market participants are watching closely.
Open interest: 161.8 million troy ounces. Registered, deliverable silver: 99.1 million troy ounces. Gap: approximately 62.7 million troy ounces.
Understanding what this means — and what it does not mean — requires a brief explanation of how commodity futures markets actually work.
HOW COMEX SILVER DELIVERY WORKS
COMEX silver futures contracts represent agreements to buy or sell silver at a specified price on a future date. Most participants in the futures market — traders, funds, speculators — never intend to take or make physical delivery. They use futures to gain price exposure to silver, and they roll their positions to later contracts as delivery dates approach.
First Notice Day is the first day on which holders of long futures positions can be required to take delivery of the underlying physical commodity. As the delivery period begins, traders who do not want physical silver must roll their positions forward or close them. Those who do intend to take physical delivery must be matched with sellers who have registered, deliverable silver available in approved COMEX warehouses.
The gap between 161.8 million oz of open interest and 99.1 million oz of deliverable silver does not automatically create a crisis. The vast majority of open interest will roll forward without ever reaching the delivery stage. This is the normal functioning of futures markets.
What the gap does create is a potential pressure point.
WHEN THE GAP BECOMES SIGNIFICANT
If a larger-than-usual share of long position holders stand for delivery — choosing to take physical silver rather than roll their positions — the available registered inventory may be insufficient to meet that demand. In this scenario, shorts who cannot source physical silver from COMEX warehouses must either find silver elsewhere (often at a premium), pay to transport it into approved warehouses, or buy back their positions in the market at higher prices.
Each of these responses adds upward price pressure. The size of that pressure depends on how many longs actually stand for delivery versus rolling.
The current gap of 62.7 million oz is notable in the context of silver’s broader physical market. Global silver mine production runs approximately 800-850 million troy ounces annually. The COMEX deliverable gap represents roughly 7-8% of annual global production — not a trivial amount if a significant portion of open interest stands for delivery.
THE STRUCTURAL CONTEXT
The COMEX deliverable gap does not exist in isolation. It is a near-term technical signal layered on top of a structural supply picture that has been tightening for years.
Silver is heading for its sixth consecutive annual structural deficit in 2026, with the global shortfall projected to widen 15% to approximately 46 million troy ounces. Since 2021, global silver stockpiles have been depleted by a cumulative 762 million troy ounces — nearly equal to an entire year of global mine production.
Approximately 70-75% of annual silver production comes as a byproduct of mining for other metals — primarily lead, zinc, copper, and gold. This means silver supply cannot be rapidly increased in response to higher prices or tighter inventory conditions. The supply constraint is structural and persistent.
Meanwhile, the industrial demand driving the deficit — solar energy, electric vehicles, AI infrastructure, 5G deployment, semiconductor manufacturing — continues to accelerate. These demand streams are tied to decade-long technological transitions that do not pause for COMEX delivery mechanics.
The combination of a near-term technical deliverable gap and a structural multi-year supply deficit is worth monitoring carefully. Historically, when physical commodity markets become physically tight — when the gap between paper promises and physical availability becomes meaningful — price discovery can shift from the paper market to the physical market, often with significant upward price implications.
This is not a guarantee of any specific outcome. Futures market mechanics are complex. Most open interest will roll without delivery. The outcome depends on choices made by individual market participants over the coming weeks.
What the 62.7 million oz gap does confirm is that the physical silver market is tighter than it has been at recent First Notice Days — and that the structural deficit story has a near-term technical dimension that adds to rather than contradicts the long-term investment thesis.

The COMEX silver gap is a reminder that paper claims on metal can exceed the metal available to deliver. Most contracts settle in cash, so the system functions, but the margin for error is thinner than the headlines suggest. Exchange data is published daily by CME Group. For a saver, the lesson is to own silver you can take delivery of, or hold it in an allocated depository through a precious metals IRA where specific bars are assigned to your account.
