How to Read This Data
Metal in LME-listed warehouses is the market's visible, exchange-tracked supply; a drain or build here changes how tight physical metal reads.
- On-Warrant Stock
- Metal directly claimable against active futures contracts. This is the most liquid form of LME inventory and the focus of most squeeze analysis.
- Cash vs 3-Month
- The gap between metal for delivery now (cash) and in three months. Cash above 3-month (backwardation) signals near-term tightness. 3-month above cash (contango) is the normal carry state.
- Depletion Signals
- Rapidly falling inventory alongside rising prices signals physical scarcity — a potential squeeze. Watch on-warrant levels closely near delivery dates.

More questions
- When did LME Zinc total stock last fall below 100K mt?
- LME Zinc total warehouse stock fell below 100K mt on July 31, 2026 and stands at 93.1K mt as of August 21, 2026.
- What is the current LME Zinc on-warrant inventory?
- LME Zinc warehouse stock stood at 93.1K mt as of August 21, 2026, per the daily LME warehouse report. The daily series we publish is total stock in LME-approved warehouses; the on-warrant/cancelled split is not reported in that feed, so we do not state an on-warrant figure.
- What is on-warrant stock on the LME?
- On-warrant stock is metal in LME-approved warehouses that is backed by a live warrant and available to settle contracts. It is the most liquid, immediately deliverable form of LME inventory and the figure most watched for squeeze risk.
- What is a cancelled warrant?
- A cancelled warrant is metal that an owner has earmarked for physical withdrawal from the warehouse. It is still on site but on its way out, so a rising share of cancelled warrants points to metal leaving the deliverable pool.
- What does falling LME inventory signal?
- Steadily falling on-warrant stock, especially alongside rising cancelled warrants and firmer prices, points to tightening physical availability. It tends to coincide with delivery pressure rather than predicting a price move on its own.
- What do contango and backwardation mean on the LME?
- Contango means metal for delivery in three months costs more than metal for delivery today, the normal state, because storing and financing metal has a cost. Backwardation is the reverse: cash metal costs more than the 3-month contract, which usually signals near-term tightness in physical supply.
