The numbers below are illustrative and rounded for clarity. Real trades vary in size, commodity, tenor, and structure; see Collateral & Transaction Structure for the full framework.
The setup
A copper trader has lined up two contracts at the same time:- A purchase contract to buy a shipment of LME Grade A copper cathodes at a discount to the market price: say $10.0M.
- An onward sale contract to sell that same shipment to an end buyer at a fixed price: say $11.0M.
Step by step
1
Escrow funding
The $10.0M is placed into a segregated escrow account at a global tier-one bank. At this point the loan is backed 1:1 by cash.Collateral state: escrowed cash · $10.0M · fully cash-covered.
2
Shipment and inspection
The copper ships on a free-on-board basis. When it reaches the delivery point, an independent, internationally recognized inspection agency (such as SGS) verifies its quality against the LME Grade A specification (an assay) and its quantity (a weighbridge certificate). These certificates are binding on all parties.Collateral state: escrowed cash · $10.0M; funds have not moved yet.
3
Payment release and title transfer
Once the full documentary package is satisfied (invoice, certificate of origin, permits, the inspection certificates, and transport documents), the escrow releases the $10.0M to the seller and title to the copper passes to the fund.For a short window (hours in this illustrative trade, though depending on the transaction it can run to days or weeks), the position faces the physical copper. Valued at the contracted sale price of $11.0M against a $10.0M loan, the commodity is worth more than the loan.Collateral state: physical copper · ~$11.0M · LTV ~91%.
4
Onward sale and settlement
In this illustrative trade, settlement of both legs occurs on the same day: the end buyer pays the contracted $11.0M and title passes to them. The loan principal plus the trade margin returns to the segregated account.Collateral state: cash again · loan repaid.
5
Redeployment
The proceeds roll into the next transaction in the program. A copper program typically runs as a rolling 12-month schedule of repeat deliveries, and over the course of the program a cash buffer can build up in the controlled account, adding a further layer of coverage.Collateral state: escrowed cash, ready for the next trade.
Where the collateral sits over time
The key thing to see from the walkthrough is that the position faces the physical commodity only for a short window between paying the seller and receiving the buyer’s funds: hours in this example, though it can extend to days or weeks. For the rest of the trade it is cash.
This is why the vault reports the collateral type per loan: whether a position currently faces escrowed cash or the physical commodity. See Transparency.
