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 Copper total stock last rise above 200K mt?
LME Copper total warehouse stock rose above 200K mt on February 13, 2026 and stands at 234.5K mt as of September 11, 2026.
What is the current LME Copper on-warrant inventory?
LME Copper warehouse stock stood at 234.5K mt as of September 11, 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.
