The Prepayment Went Out. The Cargo Did Not Come Back.
Quote from chief_editor on May 2, 2026, 4:00 amPrepayment to commodity suppliers without security creates existential risk for traders. How prepayment losses occur and why standard protections fail.
A trader wired $1.2 million to a Ghanaian manganese ore supplier as a prepayment for 15,000 MT FOB Takoradi. The prepayment was 40% of the estimated cargo value — standard in West African mining trades where suppliers need working capital to mobilize equipment, hire trucks, and begin mine-to-port haulage. The supplier had completed two previous transactions successfully, delivering 8,000 MT and 10,000 MT on time and within spec.
The supplier acknowledged receipt of the prepayment. Two weeks later, the supplier reported that trucking from the mine to Takoradi had been delayed due to road conditions during the rainy season. Four weeks later, the supplier reported that the mine had encountered a hard rock layer requiring blasting, which would delay production by another two weeks. Six weeks after the prepayment, the supplier's phone was intermittently reachable. Eight weeks after the prepayment, the supplier was unreachable. The trader sent a representative to Ghana. The mine site showed minimal recent activity. The stockpile at the mine gate was approximately 3,000 MT — far less than the contracted 15,000 MT. The supplier's office in Accra was closed.
The trader had lost $1.2 million. Legal proceedings were initiated in Ghana. The supplier was located — the individual had not fled but had diverted the prepayment to a separate business venture that had failed. The supplier had no assets sufficient to repay the advance. The legal proceedings cost approximately $45,000 and recovered nothing.
The Successful Shipments Were the Setup, Not the Track Record
The two previous successful transactions — 8,000 MT and 10,000 MT — were genuine. The supplier delivered real cargo. The trader was paid. The quality was acceptable. These transactions established trust. They also established the conditions for the larger prepayment on the third transaction.
This pattern — genuine performance on small transactions followed by default on a larger one — is among the most common prepayment fraud structures in physical commodity trade. It is not always premeditated fraud. Sometimes the supplier genuinely intends to perform but diverts the prepayment to cover other obligations, expecting to repay from future production. When future production does not materialize — because of operational problems, market changes, or simply poor management — the prepayment is gone and the supplier cannot deliver.
Industry estimates suggest that in small-to-medium mining trades in West and Central Africa, prepayment losses occur on roughly 5 to 10% of transactions where prepayments exceed $500,000 and the supplier has fewer than 5 completed transactions. The loss rate drops significantly — to roughly 1 to 2% — when prepayments are structured with security mechanisms.
The operational rule for commodity traders making prepayments is that past performance does not guarantee future performance, and prepayment security must be proportional to the amount at risk. Security mechanisms for prepayments include: standby letters of credit from the supplier's bank (the gold standard, but rarely available from small African mining companies), corporate guarantees from the supplier's parent company or principal shareholder (useful if the guarantor has verifiable assets), title to equipment or mining rights as collateral (requires local legal advice and registration), progressive drawdown (releasing the prepayment in tranches tied to verified production milestones — for example, 30% on contract signing, 30% when cargo is at the port confirmed by the trader's surveyor, and 40% on BL issuance), and physical presence at the mine during the production and haulage period (a representative on site who verifies daily production and truck movements).
The Cost of Monitoring Is a Fraction of the Cost of Loss
The trader who lost $1.2 million in Ghana did not use any of these mechanisms on the third transaction because the first two had gone well. The trader's logic was understandable: the supplier had performed, the relationship was established, and adding security mechanisms might have offended the supplier or complicated the transaction.
This logic is the reason prepayment losses recur. The absence of security is not neutral — it is an invitation to diversion, whether intentional or circumstantial. A supplier facing cash flow pressure from other obligations will use the most accessible cash first. An unsecured prepayment sitting in the supplier's account is the most accessible cash available.
The cost of a progressive drawdown structure — releasing funds in tranches against verified milestones — is administrative, not financial. The cost of a site representative during the production period is $3,000 to $8,000 per month including travel and accommodation. On a $1.2 million prepayment, these costs are 0.25 to 0.67% of the amount at risk. The trader who saved this cost lost 100% of the prepayment.
The manganese ore was eventually partially recovered — the 3,000 MT at the mine gate was secured by the trader's representative and shipped to Takoradi. The recovery — approximately $240,000 at spot market prices — reduced the net loss to $960,000. The legal proceedings produced a judgment that was unenforceable against a supplier with no attachable assets.
The first two shipments were real. The trust they built was real. The $1.2 million that followed the trust into a Ghanaian bank account did not come back. The trader's compliance file showed a supplier with a clean record. The compliance file did not show the supplier's other obligations, their cash flow position, or their intention to use the prepayment for purposes other than producing manganese ore. No compliance file does. That is why prepayment security exists — not because every supplier is dishonest, but because every unsecured prepayment is vulnerable to circumstances that the trader cannot see and the supplier may not have anticipated.
