Trade Finance Messaging
What Is MT799?
MT799 is a SWIFT Category 7 free-format message used for authenticated bank-to-bank communication when a standard, fully structured issuance message is not being sent yet.
It is commonly used as a pre-advice, confirmation of intent, or clarification step during a closing sequence.
MT799 carries information. It does not transfer funds, and it is not the same as an issued undertaking such as an SBLC or bank guarantee.
Where MT799 Sits in Real Transactions
MT799 most often appears after commercial terms are agreed and before a binding instrument is transmitted.
It is used to reduce execution risk at the last operational steps by letting banks confirm references, stated intent, or conditional readiness through authenticated channels.
Pre-advice
One bank signals that, subject to conditions, an instrument will be issued or a facility is intended to support a defined purpose.
Clarifications
Banks align references, timing, or operational details so the final issuance message does not fail due to mismatched data.
Comfort Step
Counterparties treat bank-to-bank SWIFT messaging as more credible than emails or forwarded documents because it is authenticated.
Not a Settlement Event
MT799 is not a payment instruction, not a cash block, and not collateral by itself.
MT799 vs MT760
MT799 and MT760 are often confused because both are used in trade finance workflows.
The distinction is practical: MT799 is narrative and informational. MT760 is typically associated with the transmission of a guarantee or standby-type undertaking through SWIFT.
If your contract requires an issued SBLC transmitted through SWIFT, the relevant concepts are the instrument text, governing rules, and authenticated bank-to-bank delivery. For the SBLC delivery mechanics, see our page on the
MT760 Standby Letter of Credit.
What MT799 Is Not
Any pitch that frames MT799 as an asset that can be purchased, rented, traded, or “monetized” is describing something other than standard trade finance execution.
- Not proof of funds by itself:
it can describe intent or context, but it is not cash evidence in the way many sellers expect.
- Not a guarantee or standby:
it may reference a future issuance, but it is not an issued undertaking by default.
- Not a payment instruction:
it does not move money and cannot be presented for payment.
- Not a substitute for contracts:
credible deals are driven by enforceable commercial documents and verified counterparties.
Practical Screening Questions for MT799 Requests
If a counterparty requests MT799, the goal is to determine whether the message is being used as an operational coordination step or as a proxy for a non-existent transaction.
What contract does it support?
Request the underlying commercial agreement, amount, timeline, and the specific obligation being secured.
Which banks are involved?
Identify the sending bank and receiving bank by name and BIC, and confirm the message is bank-to-bank rather than broker-forwarded.
What happens after MT799?
In real sequences, MT799 is followed by the binding instrument or agreed settlement steps, subject to conditions precedent.
Are conditions stated?
Legitimate messages are usually conditional, referencing KYC, AML, sanctions screening, credit approval, and document completion.
Common Red Flags
- Requests for “blocked MT799” or “monetizable MT799” without a named commercial contract
- Pressure to pay staged fees in exchange for screenshots or templates
- Missing counterparty identity, unclear beneficiary, or no bank coordinates
- Claims that MT799 alone proves funding or guarantees payment

FAQ
Can a company receive MT799 directly?
MT799 is generally exchanged between banks through SWIFT. Your company is the underlying client, but the message is transmitted bank-to-bank.
Is MT799 binding?
It is authenticated bank correspondence. Legal effect depends on exact wording and conditions. The enforceable obligation typically comes from the final instrument or signed facility documents.
Does MT799 replace an SBLC?
No. MT799 can be used as a pre-advice step, but it is not a substitute for an issued SBLC transmitted through authenticated channels.
Why do counterparties ask for MT799?
In serious transactions, it is a coordination step to confirm intent and align operational references. In non-serious situations, it is often requested as a proxy for funding that has not been mobilized.
