A letter of credit can turn an uncertain overseas sale into a bank-backed payment arrangement, but are letters of credit safe in every circumstance? No. They are among the most useful risk-management tools in international trade, particularly where buyer and seller have no established relationship, yet their safety rests on the detail of the credit, the banks involved and the exporter’s own discipline.
For many years, letters of credit were central to exporting from Britain to markets where information was limited, communications slow and legal remedies uncertain. The paperwork arrived by courier, documents were checked line by line, and a discrepancy that appeared trivial could delay payment. Technology has accelerated the process, but the underlying principle has not changed: a letter of credit is a promise to pay against compliant documents, not a guarantee that the commercial transaction itself will end happily.
What a letter of credit actually protects
Under a conventional irrevocable letter of credit, the buyer asks their bank, known as the issuing bank, to undertake to pay the seller provided that the seller presents the stipulated documents correctly and within the required time. Those documents may include a commercial invoice, transport document, packing list, certificate of origin, insurance certificate or inspection certificate.
This arrangement matters because the seller is not relying simply on the buyer’s willingness or ability to pay after receiving the goods. If the documents comply, the issuing bank is expected to pay according to the credit’s terms. In a properly arranged transaction, this can protect an exporter against buyer insolvency, a sudden change of mind, or the familiar excuse that goods were allegedly unsatisfactory.
However, banks deal in documents, not goods. A bank does not inspect the machinery loaded at Felixstowe, count cartons in a warehouse, or decide whether a consignment meets the buyer’s expectations. It checks whether the papers appear, on their face, to comply. This distinction is the source of both the letter of credit’s strength and its limitations.
Are letters of credit safe when the paperwork is right?
They can be very safe, but only after several questions have been answered. The first is whether the issuing bank is sound and able to transfer funds in the relevant currency. A credit issued by a major bank in a stable country presents a different level of risk from one issued by a little-known institution in a country facing exchange controls, conflict, sanctions or a shortage of foreign currency.
The second question is whether the credit has been confirmed by a bank acceptable to the exporter. Confirmation means that a second bank, often in the seller’s country, adds its own undertaking to pay provided compliant documents are presented. The exporter then has a direct commitment from the confirming bank, rather than depending solely on a distant issuing bank and the conditions in its country.
Confirmation costs money and is not automatically necessary. A long-standing customer in a financially secure market may not justify the added expense. But where the contract is substantial, the buyer is new, or political and transfer risks are material, confirmation can be the difference between a theoretical promise and a practical payment safeguard.
There is also a third question that is too often neglected: can the exporter comply with the credit exactly? A letter of credit is not safe for a firm that accepts unrealistic shipment dates, vague document requirements or conditions dependent on the buyer’s co-operation. If the credit asks for a certificate signed by the buyer after shipment, the buyer may be given an opportunity to obstruct payment. That is poor drafting, not sensible security.
The principal risks exporters still face
The most common difficulty is documentary discrepancy. A misspelt name, an inconsistent date, an incorrect description of goods, a late presentation or a transport document that does not match the credit may give the bank grounds to refuse documents. Some discrepancies are waived by buyers, but an exporter should never regard a waiver as assured, especially if market prices have moved against the buyer or the buyer is short of cash.
Fraud is another risk. Fraudulent letters of credit do exist, as do forged amendments and messages that appear to come from banks. An exporter should not act on a document emailed by an unknown intermediary without independent verification through a trusted bank. A genuine credit is normally advised through established banking channels. The pressure to ship quickly, often accompanied by an unusually attractive order, is a reason for greater caution rather than less.
Country risk can be just as serious. An issuing bank may be willing to pay but prevented from doing so by currency restrictions, sanctions, civil disturbance or state intervention. This is why experienced exporters distinguish between commercial risk, which concerns the buyer, and political or transfer risk, which concerns the environment in which the buyer and issuing bank operate.
Then there is the less dramatic but costly risk of bad contract management. A credit may oblige the seller to produce documents that the freight forwarder cannot provide, or it may require shipment in a period that does not allow for production delays. The bank will not excuse an exporter because a lorry broke down, a vessel was rolled, or a supplier delivered late. Those are commercial realities, but the credit’s timetable remains unforgiving.
How to make a letter of credit safer
The safest time to manage letter-of-credit risk is before accepting the order. Once goods are made, packed and ready for dispatch, the exporter’s room for manoeuvre is much reduced. A sensible approach is to agree the sales contract first, then ensure that the credit reflects it precisely.
Before shipment, an exporter should establish five matters:
- whether the issuing bank is acceptable and whether confirmation is needed;
- that the credit is irrevocable and subject to recognised international rules, commonly UCP 600;
- that every required document can be produced accurately and on time;
- that shipment, presentation and expiry dates are realistic; and
- that no condition requires the buyer’s discretionary approval after goods have left the exporter’s control.
These checks sound elementary, but they are where many expensive mistakes begin. The sales department may be pleased to secure an order, while the shipping department inherits an impractical credit. In a well-run exporting business, commercial, logistics and finance colleagues review the wording together. If the exporter uses a freight forwarder or documentary credit specialist, their advice should be sought before the credit is accepted, not after a discrepancy has arisen.
It is also prudent to read amendments with the same care as the original credit. A buyer may request a genuine alteration to quantity, shipment date or port. Equally, an amendment can introduce a condition that weakens the exporter’s position. No amendment should be treated as administrative routine.
Letters of credit versus other payment methods
A letter of credit is not automatically the best answer to every export sale. For established customers in low-risk markets, open-account trading may be commercially necessary and less expensive. Credit insurance, credit limits and good customer intelligence can then offer a more practical form of protection. For modest orders, advance payment or a partial deposit may be simpler.
Documentary collection occupies a middle ground, but it does not provide the bank’s undertaking to pay. The bank passes documents and seeks payment or acceptance from the buyer. If the buyer declines, the seller may still own the goods, but perhaps in a distant port with storage charges accumulating. That is a very different position from holding a confirmed, workable letter of credit.
The right method depends on the value of the order, the exporter’s bargaining position, the buyer’s record, the destination, the nature of the goods and the availability of finance. Capital equipment made to a buyer’s specification deserves a higher level of payment security than readily saleable stock. Goods with a short shelf life create their own urgency and may call for a different arrangement.
A useful discipline, not a substitute for judgement
Letters of credit remain valuable because they impose structure on an international transaction. They make both parties specify what will be shipped, when it will move and what evidence will trigger payment. In markets where trust has not yet been earned, that structure can be worth considerably more than the banking charges.
But they should never be treated as a magic shield. The exporter must assess the bank, the country, the buyer, the wording and their own ability to fulfil every condition. A confirmed credit from a sound bank, checked before production and administered carefully, is one of the safer ways to trade internationally. An unconfirmed credit with awkward terms, accepted in haste, can offer only the appearance of security.
The practical lesson is straightforward: treat a letter of credit as a carefully drafted financial contract, not merely as evidence that an order has been won. That habit protects cash, preserves margins and often prevents a promising overseas sale becoming an avoidable dispute.
