Pre-export finance (PXF) is a structured lending facility in which a bank or group of banks extends credit to a commodity producer — a mine, a farm, or a processing plant — secured against the future export revenues of a defined commodity shipment or series of shipments. The borrower is the producer; the repayment source is the proceeds from selling the commodity to a pre-agreed buyer, who may be a trading company or end-user. PXF is not a general corporate loan — it is self-liquidating, meaning repayment comes directly from the specific trade flow that the loan financed.
The difference between pre-export finance and a standard commercial loan is that PXF is secured against a physical commodity flow and repayment is structured around specific export transactions rather than general balance sheet capacity.
How a PXF Structure Works
The structure involves three core parties: the producer (borrower), the bank (lender), and the offtaker (the buyer who commits to purchase the commodity and direct payment to the bank). The relationship between these parties is documented through an offtake agreement — a contract under which the offtaker commits to purchase a defined volume of commodity from the producer over a specified period.
The process works as follows. First, the producer and a commodity trading company agree on an offtake arrangement: the trader commits to buy a fixed volume — for example, assume 10,000 metric tons of copper concentrate per month for 24 months — from the producer. Second, the producer approaches a bank with the offtake agreement as evidence of future revenue. Third, the bank lends the producer a sum — for example, assume $30 million — secured against the value of the committed offtake. Fourth, when the producer ships each month's concentrate, the offtaker (the trading company) pays for the shipment, but payment is directed to the bank's account rather than the producer's account. The bank deducts the loan repayment installment and interest from each payment and transfers the remainder to the producer. Finally, once the loan is fully repaid, payments revert directly to the producer.
For example, a cobalt mining company in the Democratic Republic of Congo (DRC) needs capital to expand its processing capacity but lacks access to domestic bank lending at viable rates. A European commodity trading company agrees to a two-year offtake for all the mine's cobalt hydroxide production. Using this offtake agreement, the mine secures a $20 million PXF facility from a trade finance bank. Monthly repayments are deducted from the trading company's payments as the shipments proceed.
What PXF Means for Commodity Traders
For a commodity trader acting as offtaker in a PXF structure, the commercial implications are significant. By committing to an offtake agreement that enables a producer's financing, the trader gains preferential or exclusive access to that producer's output — often at a price that reflects a discount to spot market levels, compensating the trader for the commitment and reliability of volumes.
The trader in a PXF structure may not provide the financing directly — the bank is the lender — but the trader's credit standing and the quality of the offtake agreement are central to the bank's willingness to lend. If the trader is a creditworthy counterparty with an established reputation, the bank has greater confidence that the offtake proceeds will flow reliably and repay the loan.
PXF structures are particularly common in emerging market mining and agricultural production, where producers have strong physical assets but limited access to local capital markets at competitive rates. Traders sourcing from these markets frequently encounter PXF as part of the commercial architecture of their supply relationships.
A limitation of PXF from the producer's perspective is that the offtake price agreed at the time of structuring the facility locks the producer into selling at that price even if market prices subsequently rise significantly. Negotiating offtake terms that include price adjustment mechanisms — floor prices, participation in upside, or periodic repricing — is therefore important for producers entering PXF arrangements.
Pre-export finance works because it aligns the interests of a producer needing capital, a bank needing security over repayment, and a trader needing supply — the physical commodity flow itself is the collateral that makes the structure viable.
