Vince Lanci's piece explains why dozens of paper claims sit on each deliverable ounce of silver, and what a falling registered stock at COMEX actually signals. The risk is not the world running out of metal but a settlement stress that resolves through price.
What was published on 25 August
On 25 August 2026, Scottsdale Mint ran a piece by Vince Lanci — a commodity trader and publisher of the GoldFix newsletter — titled "How the Comex Paper Market Can Break." It is about silver, and about one question: how many paper claims sit on top of each ounce that can actually be delivered.
A paper ounce and a physical one
Paper silver is any claim on metal: a futures contract, an option, an unallocated account at a bullion bank, a pooled account, a share in an ETF. Physical silver is the bar itself. Most of the time the two trade interchangeably, which is precisely why the paper market can be many times larger than the metal standing behind it.
Paper has a legitimate job. It is liquid and it lets an industrial user or a miner hedge without shipping bars anywhere. Lanci offers a measurement of how well it does that job: since the start of 2024, SLV and the COMEX future have returned within two points of each other, tracking day for day. That very faithfulness is what allows claims to pile up. Almost nobody needs the bar.
The ratio is tinder, not the spark
The central model of fragility is the ratio of paper claims to deliverable metal. Lanci states it carefully: by some widely cited estimates, there can be dozens of paper ounces outstanding for every ounce of registered, deliverable COMEX silver. He names no precise figure and cites no source for the estimates — worth knowing for anyone who has seen rounder numbers circulating.
The logic survives the imprecision. The higher the ratio, the further price has to travel to clear even a modest wave of delivery demand, because the metal is not there at the current price. The ratio itself causes nothing. It is dry tinder that makes a fire possible once a spark lands.
Registered and eligible: two buckets, one vault
Here the piece corrects the most common misreading of inventory headlines. COMEX warehouse silver splits into two buckets. Registered metal is pledged and immediately good to settle a futures contract; this is what actually backs delivery. Eligible metal sits in the same vault but is not pledged — it can be converted, but today it is committed to nothing.
When the feeds shout that COMEX is draining, they usually mean registered stock is falling. That is a genuine stress gauge, but metal moves between the buckets, which is why a falling registered number is, in the author's phrasing, a warning light rather than a doomsday clock.
London: the headline and the free float
COMEX in New York is the futures venue and the source of the inventory figure everyone quotes. The larger physical hub is the LBMA in London, where most real bullion is stored and traded — and much of it is already spoken for, allocated to ETFs, central banks and clients. What matters for squeeze risk is not the total London vault figure but the free float: unencumbered metal genuinely able to move, a fraction of the headline.
Why the market can break
Put it together. A paper market many multiples the size of deliverable metal, a registered bucket that can be drawn down, a London float thinner than the headline suggests, and a structural deficit eroding the cushion every year. None of it matters while paper holders are content holding paper. It matters the moment a meaningful slice of them want bars instead of claims.
Lanci is insistent about the wording: this is settlement stress, not the world running out of silver. It resolves through price, and fast, because the plumbing cannot move metal quickly enough. Hence the shape of this market — months of nothing, then the whole move at once.
What is visible in advance
Settlement stress is observable before it becomes a price headline. Surging lease rates mean physical metal is hard to borrow. Backwardation — spot above the futures curve — means people will pay a premium to hold silver now. Rising delivery notices alongside falling registered stock mean longs are standing for metal.
One detail matters as of publication: the author notes the silver curve is currently in its normal shape, with deferred contracts trading above nearer ones. There is no backwardation; the signal is not lit. We explain how the market is built. We do not give investment advice.
