Reading the Red Flags in Instrument Fraud

Standby letters of credit, bank guarantees and documentary credits are ordinary, useful tools in international trade. The fraud that surrounds them is ordinary too — it follows a small number of repeatable patterns. Once you have seen the pattern, you can screen most of these approaches out in an afternoon. This is a field guide to the ones we see most often.

A useful mental model: legitimate bank instruments move bank to bank, on the customer's own arrangements, with the fees and mechanics visible before anyone commits. Nearly every scheme below breaks one of those three properties — the channel, the ownership, or the transparency.

The advance-fee shape

Almost all instrument fraud is a variation of the advance-fee scam: you are asked to pay something real — a "reservation fee," "SWIFT transmission fee," "insurance wrap," "commitment deposit" — against a promised instrument that never arrives, or arrives worthless. The specific vocabulary changes; the shape does not. You send money first, into a chain you do not control, for value you cannot yet verify.

Red flags, in the order they usually appear

• "Leased" or "rented" SBLCs and BGs. A standby letter of credit is a contingent bank obligation, not an asset you can lease out by the month for a percentage. The "leased instrument at 6%+2%" pitch is one of the most durable frauds in the market. There is no legitimate market for renting a bank's credit to a stranger.
• Instrument "monetization" at a fixed loan-to-value. Offers to turn a leased or purchased instrument into non-recourse cash at a neat 60% or 80% LTV, in a few banking days, from a provider you have never dealt with, are a hallmark of the scheme — not a product.
• Delivery outside the banking channel. Genuine instruments are transmitted bank to bank over SWIFT (an MT760 for a guarantee, an MT799 as pre-advice). If someone offers to "hand deliver," email a PDF, or transmit an instrument through anything other than the beneficiary's own bank, stop.
• Upfront fees to non-bank accounts. Reservation, transmission, or "compliance" fees payable in advance to an individual, a broker, or an offshore company — rather than paid to your own issuing bank as part of the process — are the payload of the scam.
• Pressure and artificial scarcity. "The provider's window closes Friday." "Another buyer is ready to take the slot." Urgency exists to stop you from verifying. Real counterparties expect due diligence and are not damaged by a week's delay.
• Unverifiable "top-25 bank" claims and papered relationships. Vague references to relationships with unnamed major banks, screenshots of account balances, or "proof of funds" letters that cannot be confirmed with the issuing institution are theatre, not evidence.
• A chain of intermediaries and NCNDA gymnastics. Six brokers deep, each protected by a non-circumvention agreement, each taking a point — with no principal you are permitted to speak to — is a structure built to obscure, not to transact.

What a clean workflow looks like

By contrast, a legitimate instrument-backed transaction is quiet and verifiable. The applicant arranges the instrument through their own bank, under that bank's approval and terms. The instrument is transmitted bank to bank to the beneficiary's bank. Fees are the bank's published fees, disclosed and paid through the banking relationship. There is a real underlying trade — goods, a contract, an inspection — behind the paper. Nobody asks you to wire a fee to a personal account to "release" anything.

How we approach it

Finhanced is a commodity broker, not a bank — we do not issue, procure, lease, or monetize instruments, and we say so plainly. What we do is screen. Before we introduce counterparties, both sides clear corporate verification, sanctions and watchlist checks, and documentary review, and the deal is pattern-matched against a working library of the schemes above. If a counterparty has been approached with an instrument-based proposal and wants an independent read, our due-diligence reviews exist for exactly that: a defined-scope review and a written risk memo, so you decide with the pattern in front of you.
