The overwhelming majority of COMEX gold futures never result in physical delivery; most positions are closed or rolled before expiry. But tracking the small minority that do go to delivery, along with the underlying vault inventory data, gives a real window into physical demand pressure that the headline futures price alone does not show.
1. How the delivery process actually works
COMEX gold futures contracts (100 troy ounces each) have a defined delivery period. On "first notice day," clearing members who hold long positions and intend to take physical delivery are matched against short position holders who must deliver. A "delivery notice" is the formal document issued during this process confirming that a specific quantity is being transferred out of, or into, exchange-approved vaults. The number of notices issued on and around first notice day is public data published daily by the CME.
2. Registered versus eligible inventory
COMEX vault gold is split into two categories. "Eligible" gold meets exchange purity and bar-size standards but its owner has not made it available for delivery against a futures contract. "Registered" gold has been specifically earmarked as deliverable. Only registered stock can satisfy a delivery notice, so it is the more important figure to track. A situation where total (eligible plus registered) inventory looks stable while registered inventory falls sharply indicates that available deliverable supply is tightening even though headline vault stock appears unchanged.
3. Reading the notices-to-registered-stock ratio
Divide open interest in the front delivery month by registered ounces available. Ratios in the range of 25 to 1 or higher have historically been flagged by commodities analysts as a stress indicator, since it implies that if a disproportionate share of open interest tried to stand for delivery simultaneously, the registered stock on hand could not physically cover it without inducing a scramble to convert eligible stock to registered status or source metal externally. In practice, this rarely triggers an actual delivery failure because most positions close out in cash rather than standing for delivery, but a rising ratio is still informative about tightening physical conditions.
4. What a delivery notice spike tells you
A notably larger-than-average number of delivery notices issued on first notice day for a given contract month suggests unusually strong physical demand for that expiry, potentially from central banks, large institutional buyers, or entities specifically seeking physical bars rather than paper exposure. This data point often surfaces before it becomes visible in the spot price, since the delivery process itself does not require the price to move; it only requires enough long holders choosing physical settlement over cash settlement.
5. Where to actually find this data
- CME Group publishes daily "Delivery Notices" reports and warehouse stock reports covering registered and eligible inventory by vault operator.
- Track the data around the active delivery months, historically February, April, June, August, October, and December for gold, since that is when notices concentrate.
- Compare the current registered inventory level against its trailing 12-month range; a level near the bottom of that range alongside rising open interest is the combination worth paying closest attention to.
