A Letter of Credit (LC) gives vital security in international trade, ensuring sellers are paid and buyers receive the goods they ordered. However, not all LCs offer the same level of protection. The key distinction often lies in whether an LC is confirmed or unconfirmed.
For anyone new to trade finance, understanding this difference is essential to managing risk effectively and selecting the right structure for your transaction.
What Is an Unconfirmed Letter of Credit?
An unconfirmed Letter of Credit is the most common type of LC. It is issued by the issuing bank (the buyer’s bank), which alone is responsible for guaranteeing payment to the exporter , provided all documentary conditions are met.
The seller’s bank (the advising bank) simply forwards the LC to the exporter and, later, the documents to the issuing bank. It does not take on any payment responsibility of its own.
In short:
- The payment risk is covered only by the issuing bank.
- The exporter depends on the creditworthiness of a foreign bank , and, indirectly, the economic and political stability of the issuing bank’s country.
Unconfirmed LCs are common when:
- The issuing bank is well-known and financially strong.
- The exporter has confidence in the buyer’s country and banking system.
- The transaction involves low risk or long-standing trading relationships.
What Is a Confirmed Letter of Credit?
A confirmed Letter of Credit adds an additional layer of security. In this case, a confirming bank , usually a reputable bank in the exporter’s country , adds its own payment guarantee to of the issuing bank.
This means the exporter now has two payment assurances:
- From the issuing bank (buyer’s bank), and
- From the confirming bank (seller’s bank or another chosen institution).
If the issuing bank or the buyer fails to make payment, the confirming bank must still honour the LC, provided all documentary terms are met.
In short:
- Both banks are obligated to pay.
- The exporter is protected against political, transfer, or credit risk in the buyer’s country.
Why Add Confirmation?
Adding confirmation can make sense when:
- The issuing bank is located in a country with higher political or economic risk.
- The exporter is unfamiliar with the issuing bank’s credit standing.
- The exporter requires additional security for financing or internal policy reasons.
While confirmation increases costs (the confirming bank charges a confirmation fee), many exporters view it as a form of insurance makes sure payment certainty.
The Role of UCP 600 and SWIFT
Both confirmed and unconfirmed LCs follow by the UCP 600 rules, issued by the International Chamber of Commerce (ICC). These rules clearly define each bank’s obligations and the process for handling documents.
The LC itself moves electronically via the SWIFT network, typically through MT700 messages, which provide a standardised format for banks worldwide to exchange LC details securely and accurately.
Example
Let’s consider a simple example:
- A UK exporter sells goods to a buyer in Ghana.
- The buyer’s bank in Accra issues an LC in favour of the exporter.
- The LC is advised to the exporter through their bank in London.
If the LC is unconfirmed, the exporter depends solely on the Ghanaian bank for payment.
If the LC is confirmed, the London bank adds its own guarantee. Should the Ghanaian bank or the buyer fail to pay, the London bank must still honour the LC , giving the exporter complete peace of mind.
Final Thoughts
The choice between a confirmed and unconfirmed LC depends on the balance between risk and cost.
- For low-risk markets and trusted partners, an unconfirmed LC may be sufficient.
- For new relationships, emerging markets, or larger transactions, a confirmed LC gives a valuable safety net.
In both cases, a well-structured Letter of Credit , issued under UCP 600 and transmitted via SWIFT MT700 , makes sure clarity, standardisation, and trust across borders.
When it comes to trade finance, confirmation isn’t about extra paperwork , it’s about extra confidence.
