The silver futures market on the COMEX is approaching a critical inflection point. According to CME Group's daily metal stocks report, registered silver inventory — the metal available for immediate delivery against futures contracts — stands at approximately 76.9 million ounces, while open interest totals roughly 575.5 million ounces. The resulting coverage ratio of 13.4% marks the sixth consecutive reporting period below the 15% threshold that exchange analysts have historically identified as "stress territory."
For every physical ounce of silver available for delivery, there are now more than seven paper ounces outstanding in futures contracts. While leverage in the 5:1 to 8:1 range has been typical for COMEX operations, the persistent decline in physical inventories raises new and urgent questions about the market's capacity to meet delivery demands if they continue to rise.
Delivery Demand Accelerates
The traditional assumption underlying COMEX operations — that 97–99% of futures contracts would roll forward or cash-settle rather than demand physical delivery — began to fracture in January 2026. In a single week, 33.45 million ounces were withdrawn from registered inventories, representing roughly 26% of deliverable silver at that time. It was, by any measure, an extraordinary event: a quarter of the available physical metal exiting the exchange's vaults in seven days.
March 2026 delivery cycle data confirmed the trend was accelerating. The March contract saw 9,212 contracts delivered, equivalent to approximately 46.1 million ounces of physical silver. To contextualise: that single delivery month absorbed 60.6% of the registered inventory then available in COMEX vaults.
Lease Rates Signal Scarcity
The tightness in physical silver is perhaps best captured by the behaviour of silver lease rates. In years of ample supply, one-month silver lease rates typically trade in a range of 0.3% to 0.5%. By January 2026, this rate had exploded to approximately 8%. When market participants are willing to pay 8% annualised simply to borrow silver to ensure timely delivery, it signals a physical market that is severely out of balance.
One-month silver lease rates surged from a normal range of 0.3–0.5% to approximately 8% in January 2026 — a level not seen in decades. This is not a speculative indicator; it reflects actual physical shortage in the wholesale bullion market, where borrowers must pay a premium to secure metal for delivery.
Geographic Arbitrage Intensifies
Another compelling signal of physical stress is the persistent premium in Shanghai futures (SHFE) over COMEX pricing. As of late April 2026, SHFE silver futures traded at a premium of approximately 12–13% above COMEX — a spread that reflects both Chinese industrial demand and the logistical difficulty of moving metal from Western vaults to Eastern consumers.
The data from SchiffGold's COMEX tracking reinforces this picture: over 70 million ounces have left the Eligible category in 2026 alone, and 50 million ounces have exited Registered. Total vault outflows for the year amount to approximately 120 million ounces — roughly $9 billion worth of silver at current prices — exiting the COMEX system entirely. At this pace, analysts note, the Eligible category could be functionally empty by Q4 2026.
Backwardation Emerges
Unlike gold, where futures prices have traded above spot (contango), drawing metal from London to New York, the silver market has experienced the opposite: backwardation, where spot prices exceed futures prices. This is a classic symptom of imminent physical shortage. When consumers are willing to pay more for immediate delivery than for future delivery, it means physical metal is hard to locate today.
The structural backdrop amplifies these concerns. The World Silver Survey 2026 confirmed a sixth consecutive annual deficit of 46.3 Moz, with approximately 762 Moz drawn from above-ground stocks since 2021. Deficits alone do not create delivery events, but the progressive erosion of the above-ground inventory available to backstop a stressed COMEX creates conditions in which even a modest increase in delivery demand can have outsized consequences.
What Happens Next
The May 2026 delivery cycle is now approaching First Notice Day, and the coverage ratio remains below 15%. The question confronting the market is straightforward: if even a modest percentage of the 575.5 Moz in open interest demands physical delivery, can the 76.9 Moz of registered inventory satisfy it?
COMEX has two paths forward. It can continue to deliver eligible bars out of remaining inventory, or — if real metal runs short — it can resort to various forms of cash settlement, closing out contracts in dollars rather than delivering silver. Either path, analysts warn, carries significant price implications. The first maintains physical integrity but depletes the buffer further. The second could trigger a violent repricing as the disconnect between paper claims and physical reality becomes explicit.
As one precious metals strategist put it: "The COMEX system operated for decades on the assumption that delivery demand would remain negligible. That assumption has now been tested three times in 2026 alone — January, March, and soon May. Each test draws down the same finite pool of physical metal."
