SBLC Meaning: What a Standby Letter of Credit Is and How to Check One
By the Vanguard Verify desk · Published 2026-10-24 · Updated 2026-11-04
Short answer: SBLC stands for Standby Letter of Credit — a bank's irrevocable undertaking to pay the beneficiary if the applicant fails to perform an obligation. It is a back-up payment: it is only drawn when something goes wrong. Standbys are usually issued subject to ISP98 (International Standby Practices, published by the ICC) or UCP 600, and banks normally transmit them to each other as a SWIFT MT760.
What "standby" means
A commercial (documentary) letter of credit is the expected way to get paid: the seller ships, presents documents and is paid. A standby works the other way round — it sits in the background. The beneficiary draws on it only by presenting a demand (plus any documents the standby requires) stating that the applicant has defaulted. That is why you will also see the term standby documentary credit. If everything goes to plan, the SBLC simply expires unused.

How to check an SBLC is real
- Receive it through your own bank. A genuine standby reaches the beneficiary through an advising bank, which checks the authenticity of the SWIFT message. A PDF or a "screenshot of an MT760" sent by email proves nothing.
- Confirm the issuing bank independently. Find its official website and BIC yourself and ask your bank to confirm the message came from that BIC. Call the issuer's trade finance department only on a number you found independently.
- Read the rules clause. It should name ISP98 or UCP 600 (latest version). No stated rules is a warning sign.
- Match it to your contract. Applicant, beneficiary, amount, currency, expiry, place of presentation and drawing conditions must match what was agreed.
- Check the applicant. Is it a real, active company? Look it up in the official company registry of its country and in the GLEIF LEI search.
- Ask about confirmation. If the issuing bank or country risk is unfamiliar, ask your bank whether it will confirm the standby.
Red flags
- Offers to "lease", "rent" or "monetise" an SBLC for an upfront fee — see is a leased SBLC real?
- You are asked to pay fees before any instrument arrives at your bank.
- "Bank-to-bank only, no calls" — refusal to let your own bank verify.
- Vague drawing conditions, or no governing rules stated.
- An issuer name that resembles a well-known bank but uses a different domain or BIC.
- Very large face values with no real underlying trade or contract.

Standby Letter of Credit: a bank's irrevocable undertaking to pay the beneficiary if the applicant fails to perform.
Which rules govern an SBLC?
Usually ISP98 (International Standby Practices), published by the ICC. Some standbys are issued subject to UCP 600. The governing rules are stated in the instrument.
Is an SBLC sent by MT760?
Banks commonly issue standbys and guarantees to each other using the SWIFT MT760 message. A copy emailed by a third party is not proof that one was issued; verify through your own bank.
What is a standby documentary credit?
Another name for a standby letter of credit: a credit that is drawn only on default, by presenting a demand and any documents the standby requires.
Which banks can issue an SBLC?

Is an SBLC the same as a bank guarantee?
They do a similar job: both pay on default. SBLCs usually follow ISP98 or UCP 600; demand guarantees usually follow URDG 758.
