Standby letter of credit (SBLC)

Check the backstop payment terms, the issuer and the presentation timetable before relying on a standby.

Quick answer

A standby letter of credit is a bank undertaking that can support payment if the specified contractual default occurs, subject to its terms and required presentation. In a trade transaction, it can support an exporter's exposure to an importer's unpaid invoices. Verify the issued wording and applicable rules for the actual transaction.

Meaning and transaction use

The International Trade Administration describes a standby as drawable following contractual default, including an importer's failure to pay. Its guide includes standby letters of credit among the techniques used to support open-account trade. The specific instrument determines its operation. [S1]

Proposed review method: map the standby against the actual invoice cycle. Identify which invoices fall within the described obligations, how the amount changes, and whether the presentation window accommodates the payment due date and required documents. Review the issuer and the arrangement for authentication separately.

Worked example

Illustrative sizing example only. Assume unpaid eligible invoices total USD 300,000 and a standby has an available amount of USD 250,000. Assume a planned additional shipment would add USD 80,000 to that exposure before any receipt.

ScenarioAssumed exposureGap above standby amount
Before additional shipmentUSD 300,000USD 50,000
After additional shipmentUSD 380,000USD 130,000

Under these assumptions, the additional shipment increases the uncovered sizing gap by USD 80,000. Confirm eligibility, reductions, previous drawings and any other protection before using this calculation in a credit approval.

Decision framework

SituationProposed action
Seller agrees open-account termsCheck the standby's amount and availability against the expected exposure and invoice dates.
New shipments increase exposureRecalculate the gap before changing the customer's credit limit.
An invoice is unpaidCheck the instrument's trigger and document requirements with the appropriate bank or adviser.

Common errors to check

  • Treating possession of a copy as proof of authenticity.
  • Assuming every invoice is within the instrument's coverage.
  • Ignoring expiry while extending payment terms.
  • Treating a sizing calculation as confirmation of payment entitlement.
