SBLC vs Letter of Credit: Key Differences Explained

Side-by-side

Why the difference matters

Under a documentary credit, the beneficiary's work is producing documents that match the credit. Under a standby, the beneficiary's work is mostly waiting: it draws only if the applicant does not pay or perform. That changes what you check. For a documentary credit you check shipment dates, document lists and conditions. For a standby you check the demand wording, expiry, amount reduction clauses and governing rules.

Both are independent of the underlying contract. A bank pays a compliant demand under a standby even if the applicant disputes the default, subject to fraud exceptions under the applicable law. See how an SBLC works and ISP98 vs UCP 600.

Which one to use

Use a documentary credit when each shipment should be paid through the bank against documents. Use a standby when trade runs on open account and the seller wants protection only if the buyer does not pay, or when a contract needs a performance or advance-payment backstop. Many exporters combine open-account terms with an SBLC because it costs less admin per shipment. Compare all credit types in types of letters of credit and start from what a letter of credit is.

Worked comparison: the same buyer, two structures

A fictional Kenyan coffee exporter sells ten containers a year to a Canadian roaster. Under documentary credits, the roaster opens a credit for each shipment. The exporter presents invoices, bills of lading, certificates of origin and quality certificates every time, and is paid when they comply. That means ten sets of bank fees, ten examinations and ten chances of a discrepancy, but payment is tied to each shipment.

Under a standby, the roaster's bank issues one SBLC for the value of two shipments, valid for a year. The exporter ships on 30-day open-account terms and invoices directly. If an invoice is not paid within 15 days of its due date, the exporter presents a demand with the unpaid invoice. In a normal year, the standby is never drawn. Bank fees fall, but the exporter carries the risk of shipments above the standby amount and must watch the expiry date closely.

The right choice depends on the buyer's track record, the size of each shipment compared with the standby, and how much paperwork each side can carry. Some exporters start with documentary credits for a new buyer and move to open account with a standby once trust is established.
