MT760 vs MT700: What's the Difference?
If you work anywhere near trade finance, you've seen both codes thrown around — often interchangeably, often incorrectly. Brokers quote an "MT760 deal" when they mean an MT700. Principals ask for a documentary credit and get sent a standby. The confusion is understandable: both are SWIFT messages, both live in the same Category 7 family, and both are a bank's way of standing behind a payment. But they do different jobs, and using the wrong one — or letting a counterparty blur the line — is how deals stall at the bank and how fraud slips through. See our Documentary LC / MT700 page for how that instrument flows end to end.
This is the plain-English version. No filler, no "contact us to lease an instrument." Just what each message is, when it's used, and how to keep them straight.
The one-sentence answer
MT700 issues a documentary letter of credit — a primary payment mechanism that pays the seller when they deliver the right documents. MT760 issues a standby letter of credit or demand guarantee — a backup that only pays if someone defaults.
One is the engine of the transaction. The other is the safety net underneath it. That distinction drives everything else.
What MT700 actually is
MT700 is the SWIFT message a bank sends to issue a commercial documentary credit (a DLC, or just "LC"). The issuing bank — acting for the buyer/importer — sends it to the advising bank on the seller's side, spelling out the full terms and conditions of the credit: amount, expiry, the documents the seller must present, shipment terms, and so on.
The mechanics in practice:
- The buyer and seller agree a trade. The buyer asks their bank to issue an LC in the seller's favour.
- The bank issues it via MT700 to the seller's bank.
- The seller ships the goods and presents the required documents (bill of lading, invoice, certificates).
- If the documents comply with the LC terms, the bank pays. Full stop — payment is triggered by compliant documents, not by anyone defaulting.
A documentary credit is therefore an active payment instrument. It is the way the seller gets paid in the normal course of the deal. It's governed by UCP 600 (the ICC's Uniform Customs and Practice for Documentary Credits), and it's typically short-term, running from shipment through payment. Because MT700 has to carry detailed terms, it's a structured, field-heavy message.
What MT760 actually is
MT760 is the SWIFT message banks use to issue a standby letter of credit (SBLC) or a demand guarantee. It's sent bank-to-bank to issue the undertaking — or to ask the receiving bank to issue one. Sending an MT760 is, in effect, transmitting a guarantee of payment, so the message carries extensive detail on the parties (issuer, beneficiary, applicant, obligor, advising bank) and the underlying transaction.
The crucial behavioural difference: a standby is a payment of last resort. It sits in the background and does nothing as long as everyone performs. It only activates if the applicant defaults — at which point the beneficiary presents a demand and the issuing bank pays. Where a documentary credit is the primary route to payment, a standby is the fallback that exists in case the primary route fails.
Standbys issued by MT760 are governed by ISP98 (International Standby Practices) or, for demand guarantees, URDG 758 (Uniform Rules for Demand Guarantees). The applicable ruleset must be stated in the instrument; in the MT760 message itself this is indicated in field 40C, and if no rules apply that has to be stated explicitly too.
One practical note brokers should know: MT760 messages frequently hit SWIFT's size limit because of all the required detail. Banks extend them using MT761 continuation messages — up to seven MT761s can accompany a single MT760, for a maximum of eight linked messages. The continuations must not contradict or duplicate each other.
MT760 vs MT700, side by side
| | MT700 | MT760 |
|---|---|---|
| Issues | Documentary letter of credit (DLC) | Standby LC / demand guarantee |
| Role in the deal | Primary payment mechanism | Backup — pays only on default |
| Triggered by | Presentation of compliant documents | A default + a demand |
| Governing rules | UCP 600 | ISP98 (standby) / URDG 758 (guarantee) |
| Typical use | Paying for shipped goods | Securing performance or payment |
| Tenor | Short-term, shipment to payment | Often longer; held until expiry |
| When it pays | Every compliant deal | Only when something goes wrong |
Where the two overlap (and why people mix them up)
The blur is real, not just sloppiness. A standby letter of credit is, technically, a guarantee dressed in the form of a letter of credit — which means some banks actually issue standbys over MT700 rather than MT760, because MT700 has more fields and their LC system handles it better than their guarantee system. So you can legitimately encounter a standby on either message type depending on the bank's internal setup.
That's exactly why you can't infer the substance of an instrument purely from the message number. What governs the instrument is the ruleset named in the text (UCP 600 vs ISP98 vs URDG 758) and the operative language — whether it pays against documents in the ordinary course, or only against a demand following default. Read the instrument, not just the message code.
The fraud angle every broker should keep in mind
Because "MT760" sounds technical and authoritative, it's become a favourite prop in trade-finance fraud. The FBI's Internet Crime Complaint Center has warned that fraud actors use counterfeit SWIFT messages — specifically naming MT760 and MT799 — to make fake SBLC schemes look authentic, exploiting the fact that most victims have never seen a real one.
A few things that follow directly from understanding the instruments:
- A real MT760 is sent bank-to-bank over SWIFT, after credit approval and conditions precedent. A PDF or screenshot of an "MT760" proves nothing; it's the easiest part of the scam to fabricate.
- You cannot "lease," "rent," or "monetize" a standby. A genuine MT760 secures a specific transaction between specific parties. Anyone offering an MT760 instrument off the shelf for a percentage of face value is describing something that doesn't exist.
- MT799 is not a guarantee. It's a free-text bank-to-bank message used for proof of funds or pre-advice — far simpler than MT760, and it transfers nothing. Watch for pitches that wave around an "MT799 confirmation" as if it were the instrument itself.

Why the distinction matters at closing
Deals don't usually die because the parties picked the wrong concept — they die because the wrong instrument gets prepared, formatted, or sequenced, and the bank rejects the package. Asking for an MT700 when the deal needs a standby, naming UCP 600 on an instrument that should cite ISP98, or floating an unstructured "MT760 PDF" into a bank that expects a properly sequenced submission: each of these turns a viable deal into a stalled one.
This is the gap Dealexus closes. The platform sequences each deal so the right instrument is prepared with the right governing rules and the right fields, in the right order, before it ever reaches a bank officer — instead of being patched together over email and WhatsApp. Clean instruments, clean packages, fewer rejections.
