The Core Financing Structures

1. Letters of Credit

The letter of credit (LC) is the foundational instrument of commodity trade finance. When a buyer opens an LC in favour of a seller, the issuing bank commits to pay the seller upon presentation of specified shipping and trade documents. The buyer does not pay until goods have shipped and documents are compliant. The seller does not ship without the bank's payment commitment in place.

For commodity traders, LCs serve two purposes: they provide payment certainty to upstream suppliers when buying, and they generate a bankable payment claim that can be discounted or used as collateral when selling on deferred terms. A usance LC from a creditworthy issuing bank can be discounted immediately after compliant document presentation, converting a 90 or 180-day deferred payment into immediate cash.

2. Borrowing Base Revolving Facility

A borrowing base facility is the working capital instrument of choice for established commodity trading companies. The trader maintains a revolving credit line with one or more lenders, and the amount available to draw at any point is calculated as a percentage of eligible assets: typically 80 to 90 percent of eligible receivables and 60 to 75 percent of eligible inventory at current market value.

As inventory is sold and receivables are collected, the borrowing base reduces and the drawn balance self-liquidates. As new inventory is purchased and new invoices are raised, the borrowing base increases again. The result is a facility that automatically scales with trading volumes. A trader running $10 million per month in volume has a different borrowing base than the same trader at $5 million, without needing to renegotiate the facility.

3. Pre-Export Finance (PXF)

Pre-export finance is used by producers and exporters who have a confirmed sale but need capital to fund production, processing, or procurement before the goods are ready to ship. The lender advances funds based on the security of the offtake contract: the confirmed commitment of a creditworthy buyer to purchase the goods. Repayment flows directly from the export proceeds when the buyer pays upon delivery.

PXF is common in mining (funded against a concentrate offtake agreement), agricultural processing (funded against a forward sale to a trading house), and energy (funded against a crude sale to a refinery). The lender is effectively lending against the buyer's creditworthiness as much as the producer's own financial position.

4. Prepayment Facilities

In a prepayment structure, the buyer provides funding to the producer or seller in advance of delivery, in exchange for a committed delivery obligation and typically a discount to the forward commodity price. Unlike PXF where the lender is a bank, in a prepayment facility the financier is the commodity buyer itself.

Prepayment structures are common in oil trading, metals, and agricultural commodities where large trading houses use their own balance sheet to secure supply at advantageous prices from smaller producers who need the liquidity. The trading house benefits from a locked-in delivery at a below-market price; the producer benefits from immediate cash without bank involvement.

5. Inventory Finance and Collateral Management

When a commodity is sitting in a warehouse between purchase and sale, it represents both a capital cost and a potential source of financing. Inventory finance allows a trader or producer to borrow against the market value of goods held in storage, with the physical commodity pledged as collateral to the lender.

For the lender's security interest to be valid, the inventory needs to be under the control of an independent collateral manager: a specialist firm that issues warehouse receipts, monitors stock levels, and controls the release of goods against payment. Collateral management is the structural mechanism that allows lenders to treat physical commodities as bankable collateral rather than unverifiable assets on a balance sheet.

6. Back-to-Back Letters of Credit

A back-to-back LC structure is used by traders who are intermediating between an upstream seller and a downstream buyer. The trader receives an LC from the end buyer, and uses that LC as collateral to open a second LC in favour of the upstream supplier. The first LC (from the buyer) supports the second LC (to the supplier), allowing the trader to complete the transaction without using their own credit lines or cash.

Back-to-back LCs are common in soft commodity trading and manufactured goods trade where a trader is sourcing from one market and selling to another without the financial standing to open an independent LC from their own balance sheet.

Why Commodity Finance Requests Get Declined

Most declined commodity finance applications share the same structural weaknesses. Addressing these before approaching a lender is the difference between a fast approval and a rejection.

• No confirmed offtake from a creditworthy buyer. A purchase order from a buyer whose own financial standing cannot be verified is not sufficient collateral for a lender. The strength of the repayment source is the foundation of the facility.
• Unclear title chain. If the lender cannot establish a clean, unambiguous security interest in the commodity from purchase to sale, they cannot lend against it. Title documentation, warehouse receipts, and shipping documents must be consistent and complete.
• First trade on the proposed route with no track record. Lenders want evidence that you have completed this trade before. A well-documented history of similar transactions on the same route with the same logistics chain significantly improves approval chances.
• Approaching the wrong lender. Not all commodity finance desks cover all commodities or all geographies. A lender with no appetite for West African agricultural commodities is not going to approve a cocoa finance request regardless of the quality of the underlying trade.
• Incomplete KYC and compliance documentation. Commodity finance lenders are subject to the same KYC and AML requirements as any other bank. Incomplete or inconsistent beneficial ownership documentation is one of the most common reasons for transactions stalling.
• Over-leveraged structure. Requesting 100 percent financing with no equity contribution signals to a lender that the borrower has no skin in the game. Most commodity facilities are structured with a minimum equity contribution of 10 to 25 percent of the transaction value.

Frequently Asked Questions

• How do commodity traders finance the purchase of physical goods? +
  Physical commodity traders finance purchases through several instruments depending on the trade structure and their banking relationships. The most common are letters of credit, borrowing base revolving credit facilities, pre-export finance, and prepayment facilities. The right structure depends on where the trader sits in the supply chain, whether they are buying from producers or selling to end buyers, and how predictable their trade flows are.
• What is a borrowing base facility and how does it work for commodity traders? +
  A borrowing base facility is a revolving credit line where the amount a trader can draw at any point is calculated against the value of eligible assets — typically trade receivables, inventory held in a warehouse, or goods in transit with clear title documentation. As the trader sells goods and collects receivables, the borrowing base reduces and the facility self-liquidates. When new inventory is purchased or new invoices are raised, the borrowing base increases again. This structure suits traders well because it provides flexible working capital that scales automatically with the size of their book.
• What is pre-export finance and who uses it? +
  Pre-export finance (PXF) is a facility where a lender advances funds to a producer or exporter before goods are produced or shipped, based on the security of a confirmed purchase order or offtake agreement with a creditworthy buyer. The advance is repaid from the proceeds of the export when the goods are delivered and paid for. PXF is used primarily by commodity producers and trading companies that have secured a confirmed offtake but need capital to source the underlying commodity.
• What is the difference between pre-export finance and a prepayment facility? +
  In a pre-export finance structure, the lender is a bank or financial institution that advances funds to the exporter against a confirmed offtake contract. In a prepayment facility, the buyer itself advances funds directly to the producer or seller ahead of delivery, typically at a discount to the forward commodity price, in exchange for a committed delivery obligation. Both structures create a financing obligation secured against the commodity flow, but the source of funding and the legal relationship differ significantly.
• How does an LC work in a physical commodity transaction? +
  In a physical commodity transaction, the buyer instructs its bank to issue a letter of credit in favour of the seller. The LC specifies the documents the seller must present to receive payment — typically including a bill of lading, commercial invoice, certificate of origin, weight certificate, and inspection certificate. When the seller ships the goods and presents compliant documents, the issuing bank is obligated to pay. The LC separates the payment obligation from the buyer's general credit risk, which is why sellers in cross-border commodity transactions frequently require one.
• What is tolling finance and when is it used in commodity trading? +
  Tolling is an arrangement in which a commodity owner retains title to raw material and pays a processing facility a fee to transform it into a finished product. Tolling finance supports this by funding the raw material purchase while the owner retains title throughout the processing cycle. It is used in metals refining, agricultural processing, and energy refining where the trader or producer does not own the processing facility but controls the feedstock.
• What do commodity trade finance lenders look at when assessing a facility request? +
  Commodity trade finance lenders assess the quality and creditworthiness of the offtake counterparty, the commodity type and its liquidity in the secondary market, the legal structure for title and security over the commodity at each point in the trade flow, the track record of the borrower in executing the specific trade route, the jurisdiction risk of the countries involved, and the borrower's equity contribution. Lenders with strong commodity desks are assessing the trade itself as the primary source of repayment, not just the borrower's balance sheet.
• Can a new or small trading company access commodity trade finance? +
  Yes, though the structuring needs to reflect the limited track record. New or small trading companies typically need to demonstrate a confirmed offtake from a creditworthy buyer, clear title and control over the commodity at each stage, a management team with direct experience in the specific trade route and commodity, and sufficient equity contribution. The most accessible entry point is usually a transaction-by-transaction structure rather than a revolving facility, building toward a borrowing base line as the track record develops.
• What commodities do trade finance lenders typically cover? +
  The most active commodity trade finance markets cover base metals (copper, aluminium, zinc, lead, nickel), precious metals (gold, silver), energy commodities (crude oil, refined products, LNG), agricultural soft commodities (cocoa, coffee, cotton, sugar, cashew, sesame), grains and oilseeds (wheat, corn, soybeans, palm oil), and ferrous metals (iron ore, steel). Lender appetite varies significantly by commodity and jurisdiction, making lender matching one of the most important variables in a successful facility placement.
• What is the role of a collateral manager in commodity trade finance? +
  A collateral manager is an independent third party appointed to monitor and control physical commodity inventory pledged as collateral under a financing facility. The collateral manager issues warehouse receipts or collateral monitoring reports that confirm the existence, quantity, and quality of the goods, and controls the release of inventory against repayment of the corresponding portion of the facility. Lenders require collateral management in transactions where the goods are held in a warehouse or storage facility as the primary security, particularly in emerging markets.
