Structured commodity finance lends against the goods and their sale, so the structure carries the credit

Short-term finance for traded commodities, repaid when the goods are sold. Warehouse receipts, a margin below market value and regular checks on the goods protect the finance provider.
Terms like this have a quick explainer. Tap or hover on them.
01 · What it is
The goods and their sale repay the finance
is a type of built around goods such as metals, energy and crops. The Basel 2 bank capital rules, as reproduced by UNCTAD, describe it as structured short-term lending to finance reserves, inventories or receivables of exchange-traded commodities. In plain terms, the money pays for stock in storage or for goods already sold.
The key point is where repayment comes from. Under the same definition, the finance is repaid from the money raised by selling the commodity (UNCTAD). The company that owes the money has no separate way to repay it. The structure, meaning the security, margins and checks around the goods, is designed to compensate for that company's credit quality.
Two standard building blocks sit underneath. The first is : a loan to a seller to source, make or convert goods that are then delivered to a buyer, as the Global Supply Chain Finance Forum (GSCFF) defines it. The second is : a loan or advance for holding or warehousing goods, with a security interest (a legal claim on the goods) and a measure of control, per the GSCFF. See our structured commodity finance instrument card.
02 · Collateral base
The provider advances less than the goods are worth, and the gap moves with price
Finance providers advance only a percentage of the goods' value, the GSCFF notes. The part they hold back is the . It is a cushion in case prices fall.
When several goods back one facility, the GSCFF describes a variation. A maximum level of finance is set against the calculated market value of the goods, less a margin that can vary with quantity or quality. Each lot's figure is its . The total across all lots is the , and it caps how much the company can draw. Our asset-based revolving facility card covers this kind of facility.
Take two illustrative lots. Lot A is worth USD 1,000,000 with a 20% margin, so its lending value is USD 800,000. Lot B is worth USD 500,000 with a 30% margin, so its lending value is USD 350,000. The collateral base is USD 1,150,000. With USD 1,000,000 drawn, the headroom, or room left to draw, is USD 150,000.
Now let prices fall 10%. The collateral base drops to USD 1,035,000 and the headroom shrinks to USD 35,000. Interest on the USD 1,000,000 drawn for 60 days at an illustrative 5.00% is USD 8,333.33, on a 360-day year.

Lending value equals market value times one minus the margin. The collateral base is the sum of the lending values. Headroom equals the collateral base minus the amount drawn. Interest equals the amount drawn times the rate times days over 360, following the ARRC Actual/360 convention and the Federal Reserve H.15 annualization.
Our Research Desk applied the GSCFF margin approach: lending value = market value x (1 - margin); interest = drawn x rate x days / 360. Margins and rates are for illustration and are not Ossiano pricing.

03 · Control of goods
Warehouse receipts and regular checks turn stock into security
The finance provider takes security over the goods through negotiable or warrants, or through an assignment of rights, the GSCFF sets out. A warehouse receipt is the paper or electronic record a storage business issues for the goods it holds. A negotiable receipt can act as a , so whoever holds it can claim the goods.
Checks matter as much as paperwork. Inventory finance risks are mitigated by robust monitoring, reporting and audit, the GSCFF says. Those checks cover the deals, the systems and the controls. Some deals use a , an independent firm that watches the stored goods for the finance provider.
The law now backs the receipt. UNCITRAL adopted the on June 26, 2024, and the UNIDROIT Governing Council adopted it on May 8, 2024, according to UNCITRAL. It lets goods be used as collateral while they are stored in warehouses, by using warehouse receipts. The earlier UNCITRAL Model Law on Secured Transactions (2016) covers security over all types of movable property, including goods and receivables.

Prepayment step 8 is our Research Desk's reading.
04 · Prepayment and offtake
Prepayment ties the finance to future deliveries
In , a bank funds an international company, which uses the money to prepay a local company for buying and processing commodities, as UNCTAD describes. The local producer then pays back in goods. The deal usually rests on an , a contract to buy the producer's future output.
A disclosed example: GeoPark executed an offtake and prepayment agreement with Vitol in May 2024. Amounts drawn can be repaid through future oil deliveries, and the interest cost is based on plus a margin, according to GeoPark's Form 20-F for 2025. See our prepayment finance instrument card.
Here is how the deliveries do the work, in an illustrative case. A buyer prepays USD 1,000,000 at 7.00% a year. The producer delivers goods worth USD 200,000 each month, and USD 100,000 of each delivery is set off against the prepayment. Each month's interest, on a 30-day month and a 360-day year, is paid first. The prepayment is cleared in 11 months, with total interest of USD 33,419.94.
is a related structure. Under Century Aluminum's Grundartangi tolling agreements, Glencore provides alumina and receives primary aluminum in return for tolling fees based on the primary aluminum price, according to Century's Form 10-K for 2013. The smelter is paid a fee for its work. See our tolling instrument card.
05 · Development finance
Development banks share the risk in farm commodity deals
such as the IFC take part in these structures. Under its Global Warehouse Finance Program, IFC participates up to 50 percent in short-term loans to agricultural commodity producers or traders against warehouse receipts or equivalent. IFC says lets banks shift risk from a business's fixed assets to the commodities that farmers produce.
IFC's SUCDEN II loan, disclosed July 31, 2024, funds the procurement and export of cocoa beans. The loan is EUR 250 million: EUR 120 million on IFC's own account and EUR 130 million mobilized from FMO (EUR 80 million) and the OPEC Fund (EUR 50 million). The IFC Board-approved amount is USD 363.98 million. The loan has a 1-year , renewable each year for up to 4 years.

06 · Title and records
Court cases show why receipts and title are checked
In Mercuria Energy Trading v Citibank (2015), the English Commercial Court looked at deals valued at about USD 271 million to USD 272 million. It found that handing over warehouse receipts without was not valid delivery of the metal. Attornment is the warehouse operator's confirmation that it now holds the goods for the new party.
In ED&F Man Capital Markets v Come Harvest Holdings (2022), the court found that 92 warehouse receipts for nickel were forgeries. The total paid under the purchase contracts and linked hedging contracts was USD 284,536,139.23.
That is why the GSCFF lists monitoring, reporting and audit among its core risk controls. Our guides on title and ownership in commodity trade and fraud controls in trade finance go further.
07 · Ossiano view
The structure, the goods and the paperwork carry the credit
OBSERVATION 01
Repayment sits in the cargo
Basel 2 describes finance repaid from commodity sale proceeds, with a structure designed to compensate for the company's credit quality. That lets producers and traders finance stock on the strength of the goods.
OBSERVATION 02
The law now backs the receipt
UNCITRAL adopted the Model Law on Warehouse Receipts on June 26, 2024, so goods can be used as collateral while stored. States that enact it give receipts a common legal footing.
OBSERVATION 03
Development finance brings in co-lenders
SUCDEN II mobilized EUR 130 million alongside IFC's EUR 120 million, and IFC's warehouse program shares up to 50 percent of loans. Shared risk widens the pool of lenders for farm commodity deals.
Summary
Structured commodity finance lets the goods carry the credit
Structured commodity finance is short-term finance for exchange-traded commodities, repaid from the sale of the goods. The finance provider advances less than the goods are worth to keep a margin of protection. It takes security through warehouse receipts or an assignment of rights, and it monitors the goods. A price fall shrinks the collateral base, so headroom needs watching.
Prepayment and tolling link finance to future deliveries. Development banks such as the IFC share the risk, and the 2024 Model Law on Warehouse Receipts gives receipts a common legal basis where states adopt it.
