The commercial transaction sits underneath it. An MT700 carries the issuance of a documentary credit. An MT707 communicates an amendment. An MT740 establishes reimbursement authority. An MT760 carries a demand guarantee or Standby Letter of Credit. An MT765 carries a demand under such an undertaking. An MT799 provides free-format bank-to-bank communication. Those messages perform very different functions. Understanding the distinction matters for importers, exporters, commodity traders, trade-finance lenders, treasury teams and anyone negotiating bank-issued instruments. ### Table of Contents 1.

[Financely Trade Finance Advisory](#financely) ## What SWIFT Actually Does in Trade Finance SWIFT provides a secure financial-messaging network and standardized message formats used by participating institutions. Banks use those formats to communicate instructions and information about trade instruments. The network separates messaging from the underlying credit decision. When a bank sends an MT700, the bank has already gone through its internal process for issuing the documentary credit. The message communicates the resulting undertaking through the banking channel. The same principle applies to an MT760\. The issuing institution first approves the contingent exposure and reimbursement arrangement. MT760 then carries the guarantee or standby undertaking. **SWIFT is the communication infrastructure. Credit approval, collateral, reimbursement obligations and the legal undertaking remain with the participating banks and transaction parties.** ## The SWIFT Categories That Matter Most in Trade Finance Traditional trade-finance messaging primarily uses two MT categories. ### Category 7 Documentary credits, demand guarantees, Standby Letters of Credit, reimbursement and associated trade messages. ### Category 4 Collections and cash-letter messages, including documentary collection acknowledgements, acceptance, payment and non-payment notices. Payments generated by a trade transaction sit in a separate payments architecture. Since the November 2025 cross-border payments migration milestone, ISO 20022 messages such as `pacs.008` and `pacs.009` have become the standard cross-border payment instruction format. That separation matters. A documentary credit message and the eventual movement of cash perform different functions. ## The Main Category 7 Messages at a Glance | Message | Primary Function | | --------- | --------------------------------------------------------- | | **MT700** | Issue of a Documentary Credit | | **MT701** | Continuation of documentary credit issuance | | **MT705** | Pre-Advice of a Documentary Credit | | **MT707** | Amendment to a Documentary Credit | | **MT708** | Continuation of documentary credit amendment | | **MT710** | Advice of a Third Bank's or Non-Bank's Documentary Credit | | **MT711** | Continuation of MT710 advice | | **MT720** | Transfer of a Documentary Credit | | **MT721** | Continuation of transferred credit | | **MT730** | Acknowledgement | | **MT732** | Advice of Discharge | | **MT734** | Advice of Refusal | | **MT740** | Authorization to Reimburse | | **MT742** | Reimbursement Claim | | **MT744** | Notice of Non-Conforming Reimbursement Claim | | **MT747** | Amendment to an Authorization to Reimburse | | **MT750** | Advice of Discrepancy | | **MT752** | Authorization to Pay, Accept or Negotiate | | **MT754** | Advice of Payment, Acceptance or Negotiation | | **MT756** | Advice of Reimbursement or Payment | | **MT759** | Ancillary Trade Structured Message | | **MT760** | Issue of Demand Guarantee or Standby Letter of Credit | | **MT761** | Continuation of MT760 | | **MT765** | Guarantee or SBLC Demand | | **MT767** | Amendment to Demand Guarantee or SBLC | | **MT768** | Acknowledgement of Guarantee or Standby Message | | **MT769** | Advice of Reduction or Release | | **MT775** | Continuation of MT767 amendment | | **MT785** | Guarantee or SBLC Non-Extension Notification | | **MT786** | Guarantee or SBLC Demand Refusal | | **MT787** | Guarantee or SBLC Amendment Response | | **MT790** | Advice of Charges, Interest and Other Adjustments | | **MT791** | Request for Payment of Charges, Interest and Expenses | | **MT795** | Queries | | **MT796** | Answers | | **MT798** | Proprietary trade message / corporate trade envelope | | **MT799** | Free Format Message | ## MT700: Issue of a Documentary Credit MT700 is the central SWIFT message for issuing a documentary letter of credit. The issuing bank sends it to the advising bank or another bank involved in advising the beneficiary. The message carries the core commercial and documentary terms of the credit, including amount, applicant, beneficiary, expiry, availability, shipment conditions, goods description, required documents and additional conditions. For traders, MT700 represents the banking expression of the agreed letter of credit structure. Financely covers MT700 issuance in greater detail in our [MT700 guide](https://www.financely-group.com/mt700-explained?ref=blog.financely.io) and [MT700 documentary letter of credit issuance](https://www.financely-group.com/mt700-dlc-issuance-trade-finance-solutions?ref=blog.financely.io) services. ## MT701: Continuation of the Documentary Credit An MT700 has finite message and field capacity. Where the documentary credit requires additional space, MT701 provides continuation capacity. The MT701 therefore belongs to the same issuance package as the MT700. Parties reading a credit transmitted across MT700 and one or more MT701 messages need to review the entire set together. ## MT705: Pre-Advice of a Documentary Credit MT705 communicates advance notice of a documentary credit before the full operative credit is issued. A pre-advice can help the beneficiary prepare for the incoming facility or provide early comfort that issuance is progressing. The parties should distinguish the pre-advice from the operative MT700. Commercial contracts sometimes create confusion by treating any SWIFT communication as final issuance. The message function should govern that interpretation. ## MT707: Amendment to a Documentary Credit MT707 carries amendments to an existing documentary credit. Common amendments include: - Increasing or reducing the credit amount - Extending the expiry date - Changing the latest shipment date - Changing goods specifications - Changing required documents - Changing shipment or delivery terms - Changing tolerance - Changing confirmation instructions - Changing additional conditions Where additional space is needed, MT708 provides the continuation. Amendments should be reviewed against the entire original credit rather than read in isolation. ## Cancelling a Documentary Credit SWIFT Category 7 treats cancellation of a documentary credit through the amendment process. The relevant bank therefore uses the MT707 framework for the cancellation communication rather than treating cancellation as an unrelated free-format request. This matters because cancellation affects an existing bank undertaking and the rights already created under it. ## MT710: Advice of a Third Bank's Documentary Credit MT710 appears when a bank advises a documentary credit that it received from another bank rather than issuing the underlying credit itself. This frequently arises in multi-bank structures and cross-border relationships where the issuing bank reaches the beneficiary through one or more intermediary banks. MT711 provides continuation capacity. The beneficiary should continue distinguishing among the issuing bank, advising bank and any confirming bank. Those roles carry different obligations. Our [issuing bank, advising bank and confirming bank guide](https://www.financely-group.com/issuing-bank-vs-advising-bank-vs-confirming-bank?ref=blog.financely.io) covers those distinctions. ## MT720: Transfer of a Documentary Credit MT720 carries the transfer of a transferable documentary credit. This matters in intermediary trading structures where the first beneficiary transfers all or part of a transferable credit to a second beneficiary. The underlying credit needs to permit transfer under its governing terms. MT721 provides continuation where the transferred credit requires additional message capacity. Transfer structures require careful handling of amounts, unit prices, expiry, shipment dates, presentation periods and document substitution rights. ## MT730: Acknowledgement MT730 acknowledges receipt of a documentary credit message. Its function is administrative and operational. An acknowledgement should never be confused with another bank adding confirmation, providing funding or accepting the underlying applicant's credit risk. ## SWIFT Messages for Documentary Discrepancies Documentary credits pay against complying presentations. When presented documents contain discrepancies, banks need structured communications around those discrepancies and the resulting instructions. ### MT750: Advice of Discrepancy MT750 advises that documents presented under the credit contain discrepancies. Typical discrepancies can involve: - Late shipment - Late presentation - Invoice inconsistencies - Transport-document issues - Missing certificates - Incorrect quantities - Document dates - Insurance-document defects - Inconsistent descriptions ### MT752: Authorization to Pay, Accept or Negotiate MT752 provides authorization to pay, accept or negotiate in the relevant documentary-credit context. It becomes particularly relevant where discrepancies have been referred and the issuing bank subsequently authorizes action. ### MT754: Advice of Payment, Acceptance or Negotiation MT754 advises another bank that payment, acceptance or negotiation has taken place under the documentary credit. ### MT734: Advice of Refusal MT734 communicates refusal of documents under a documentary credit. The refusal process interacts closely with UCP 600 requirements concerning examination and notice. ### MT732: Advice of Discharge MT732 advises discharge in the relevant trade-finance context after obligations or claims have been settled according to the transaction. ## SWIFT Reimbursement Messages Letter of credit settlement can involve a reimbursing bank separate from the issuing bank and nominated bank. This creates a second messaging chain around the credit. ### MT740: Authorization to Reimburse The issuing bank sends MT740 to the reimbursing bank authorizing reimbursement under the documentary credit. The message establishes the authority under which the reimbursing bank can honor a compliant reimbursement claim. ### MT742: Reimbursement Claim The claiming bank uses MT742 to claim reimbursement. The reimbursing bank examines that claim against the reimbursement authorization rather than re-examining the entire commercial transaction. ### MT744: Notice of Non-Conforming Reimbursement Claim MT744 tells the claiming bank that the reimbursement claim fails to conform to the reimbursement authorization on its face. Reasons can include excessive amounts, missing information, different claiming-bank details or another inconsistency with the authorization. ### MT747: Amendment to an Authorization to Reimburse MT747 modifies the reimbursement authorization previously communicated under MT740. Changes might follow an amendment to the underlying documentary credit or another adjustment to the reimbursement mechanics. ### MT756: Advice of Reimbursement or Payment MT756 advises reimbursement or payment within the trade-finance settlement process. ## A Simple Reimbursement Chain **Issuing bank issues the documentary credit.** MT700 travels through the relevant advising route. **Issuing bank authorizes reimbursement.** MT740 goes to the reimbursing bank. **Beneficiary presents compliant documents.** The nominated or negotiating bank processes the presentation. **Claiming bank requests reimbursement.** MT742 is sent to the reimbursing bank. **Reimbursing bank settles or raises an issue.** A conforming claim proceeds toward reimbursement; a non-conforming claim can generate MT744. ## MT760: Demand Guarantees and Standby Letters of Credit MT760 is the principal Category 7 message for issuing a demand guarantee or Standby Letter of Credit. It can carry instruments supporting financial obligations, contractual performance and other eligible obligations according to the structure. For an SBLC, the underlying rules may incorporate ISP98 or, in appropriate cases, UCP 600\. Demand guarantees frequently incorporate URDG 758. MT760 identifies the issuance communication. The underlying instrument establishes the bank's undertaking. Financely covers this separately in our [MT760 Standby Letter of Credit guide](https://www.financely-group.com/mt-760-standby-letter-of-credit?ref=blog.financely.io). ## MT761: Continuation of MT760 MT761 carries continuation information when the guarantee or Standby Letter of Credit exceeds the capacity available in the primary MT760 message. The complete undertaking therefore consists of the relevant MT760 together with any associated continuation messages. ## The Guarantee and SBLC Lifecycle Messages Modern Category 7 provides considerably more structure around guarantees and standbys than the internet's usual MT760-only discussion suggests. ### MT765: Guarantee or Standby Letter of Credit Demand MT765 carries a demand for payment under a guarantee or Standby Letter of Credit. This is an important distinction from MT760. MT760 issues the undertaking. MT765 communicates a demand under that undertaking. ### MT767: Amendment to a Guarantee or SBLC MT767 carries an amendment to an existing guarantee or Standby Letter of Credit. Changes may cover amount, expiry, beneficiary information, underlying obligation, reduction mechanics or other instrument terms. MT775 provides continuation space for the amendment. ### MT768: Acknowledgement of a Guarantee or Standby Message MT768 acknowledges receipt of the relevant guarantee or standby communication. ### MT769: Advice of Reduction or Release MT769 communicates a reduction or release affecting the outstanding undertaking. This can arise when contractual exposure falls as work progresses, advance payments amortize or the beneficiary releases part of the guarantee amount. ### MT785: Non-Extension Notification MT785 communicates non-extension of a guarantee or Standby Letter of Credit. This becomes particularly important for automatically extendable instruments where the issuer elects against renewal within the required notice period. ### MT786: Demand Refusal MT786 communicates refusal of a demand presented under a guarantee or Standby Letter of Credit. ### MT787: Amendment Response MT787 communicates the response to an amendment of a guarantee or standby, including acceptance or rejection as appropriate. ## MT759: Ancillary Trade Structured Message MT759 deserves far more attention than it receives. It provides structured communication relating to an existing trade transaction where another dedicated message type fails to cover the required communication. SWIFT describes uses including financing requests and fraud alerts relating to documentary credits, guarantees, standbys and other undertakings. Where MT759 fits the communication, its structured fields provide more transaction context than a completely free-format MT799. That makes MT759 useful for operational communications that fall outside the principal issuance, amendment, reimbursement and presentation messages. ## MT799: Free Format Message MT799 is a free-format Category 7 message. Banks can use it for trade-related communication where the required information fits no more specific message type. Its flexibility has also made MT799 one of the most misrepresented SWIFT messages on the internet. MT799 carries text. Its commercial significance depends entirely on what the sending bank actually says, who sent it, why it was sent and which transaction it references. A genuine MT799 from a bank can contain useful information. The message type itself supplies no standardized promise to pay. Financely's dedicated [MT799 guide](https://www.financely-group.com/what-is-mt799?ref=blog.financely.io) covers the issue in more depth. ## MT799 and “Proof of Funds” There is no universal rule making MT799 a standardized proof-of-funds instrument. A bank can use free-format text to communicate information about its customer or a transaction subject to its internal policies. The receiver still has to read the actual wording. A statement that a bank maintains a relationship with a customer differs significantly from an irrevocable undertaking to pay. Trading jargon often collapses those distinctions and produces sequences such as “MT799 first, MT760 second, MT103 after.” Real banking transactions follow the legal and credit structure of the underlying deal. ## MT799 and “RWA” Messages “RWA” generally means ready, willing and able in the informal language used around some transactions. SWIFT has no universal MT799 subtype that automatically turns a free-format message into a binding RWA commitment. The receiving bank examines the sender, text, reference, context and underlying relationship. The same applies to messages described online as “bank capability messages,” “pre-advice,” “bank-to-bank confirmation” or similar labels. Start with the actual message type and the actual wording. ## SWIFT Messages for Documentary Collections Documentary collections use a different SWIFT category from documentary credits. Category 4 includes the principal messages used between banks handling collections. | Message | Function | | --------- | ----------------------------------------------- | | **MT400** | Advice of Payment under a collection | | **MT410** | Acknowledgement of receipt of a collection | | **MT412** | Advice of Acceptance of one or more drafts | | **MT416** | Advice of Non-Payment or Non-Acceptance | | **MT420** | Tracer concerning documents sent for collection | | **MT422** | Advice of Fate and Request for Instructions | | **MT430** | Amendment of collection instructions | The distinction between collections and documentary credits remains fundamental. Under a documentary collection, banks handle documents and collection instructions without creating the same independent payment undertaking associated with an issuing bank under a documentary credit. Financely covers the commercial structure in our [documentary collections guide](https://www.financely-group.com/what-is-documentary-collections-and-how-it-works?ref=blog.financely.io). ## MT798: The Corporate Trade Envelope MT798 sits in a different part of the trade messaging architecture. Large corporates working with several banks can use MT798 as a standardized corporate-to-bank and bank-to-corporate trade channel. SWIFT describes MT798 as a trade envelope supporting: - Import letters of credit - Export letters of credit - Guarantees - Standby letters of credit A corporate can use the framework to submit an LC application, request an amendment and receive advice or notification through a standardized multi-bank channel. The MT798 can envelope transaction details corresponding to established bank-to-bank trade messages. For multinational treasury teams, this reduces dependence on separate proprietary portals for each banking relationship. ## MT798 Versus MT799 | MT798 | MT799 | | ---------------------------------------------- | -------------------------------------------------- | | Structured corporate trade messaging framework | Free-format bank message | | Supports standardized trade workflows | Used for narrative communication | | Common in corporate-to-bank trade integration | Common in bank-to-bank miscellaneous communication | | Can envelope detailed LC and guarantee data | Meaning comes from the text entered by the sender | ## What About MT103 and MT202? MT103 and MT202 belong to payments rather than the documentary-credit issuance architecture. Historically, MT103 became synonymous with customer credit transfers and MT202 with financial-institution transfers. The cross-border payments environment has since moved to ISO 20022. On 22 November 2025, SWIFT ended the MT/ISO 20022 coexistence period for cross-border payment instructions. ISO 20022 now provides the standard cross-border payment language. Relevant payment messages include: | Legacy MT Context | Current ISO 20022 Direction | Function | | ----------------- | --------------------------- | ----------------------------------------------------- | | MT103 / MT103 STP | **pacs.008** | FI-to-FI customer credit transfer | | MT202 / MT202 COV | **pacs.009 / pacs.009 COV** | Financial institution credit transfer / cover payment | SWIFT currently provides chargeable contingency conversion for certain legacy payment MTs, but ISO 20022 is the destination format for cross-border FI-to-FI payments. **This distinction matters for trade-finance fraud screening.** An MT103, pacs.008 or other payment instruction can evidence a payment instruction in the relevant context. It says nothing by itself about the legitimacy of an unrelated SBLC, commodity contract or alleged investment program. ## A Letter of Credit Can Generate Both Trade and Payment Messages A documentary credit transaction can involve several layers of bank communication. Category 7 messages govern issuance, amendments, presentation handling and reimbursement. The resulting movement of funds then travels through the payments infrastructure. That is why asking “which SWIFT code pays the letter of credit?” oversimplifies the process. The payment route depends on the banks, accounts, reimbursement structure and settlement architecture involved. ## Important Fields in an MT700 Trade practitioners usually care as much about the fields inside MT700 as the message code itself. | Field | Commercial Significance | | --------------------------- | ----------------------------------------------------------------------- | | **20** | Documentary credit number / reference | | **31C** | Date of issue | | **31D** | Expiry date and place | | **50** | Applicant | | **59** | Beneficiary | | **32B** | Currency and amount | | **39A / related 39 fields** | Amount tolerance and related credit amount terms | | **41a** | Available with / by | | **42C** | Draft tenor where applicable | | **43P** | Partial shipments | | **43T** | Transshipment | | **44 series** | Shipment, taking in charge, destination and latest shipment information | | **45A** | Description of goods and/or services | | **46A** | Documents required | | **47A** | Additional conditions | | **71D** | Charges | | **48** | Period for presentation | | **49** | Confirmation instructions | | **78** | Instructions to the paying, accepting or negotiating bank | ## Field 46A and Documentary Compliance Field 46A deserves particular attention because it specifies the documents required under the credit. These might include: - Commercial invoice - Bill of lading - Air waybill - Packing list - Certificate of origin - Inspection certificate - Insurance document - Weight certificate - Quality certificate - Beneficiary certificate Payment risk frequently emerges from drafting this field poorly. Every unnecessary document creates another possible discrepancy. ## Field 47A and Additional Conditions Field 47A often becomes the dumping ground for transaction conditions that failed to fit elsewhere. This can create operational problems. Conditions should remain documentary and objectively examinable where they affect presentation. Long commercial narratives, vague performance requirements and documents controlled exclusively by the applicant can make a credit difficult to use. Experienced structuring therefore aims for a credit that protects the applicant while remaining presentable by the beneficiary. ## MT700 Under UCP 600 Most modern commercial documentary credits incorporate UCP 600. UCP 600 governs matters including bank obligations, examination of documents, honour, negotiation, discrepancies and other documentary-credit mechanics. SWIFT supplies the message format. UCP supplies the rules when incorporated into the credit. Those layers work together while serving different functions. ## eUCP and Electronic Presentation Where electronic records form part of the presentation, parties can also incorporate the eUCP supplement alongside UCP 600. This becomes increasingly relevant as bills of lading, warehouse documents and other trade records move into electronic form. The SWIFT message issuing the credit and the platform handling electronic documents can therefore sit within the same wider transaction while performing different jobs. ## Example: Full Documentary Letter of Credit SWIFT Flow Consider an importer buying USD 5 million of industrial equipment from an overseas manufacturer. **Importer applies to its bank for a documentary credit.** The issuing bank completes credit underwriting and approves the facility. **Issuing bank sends MT700.** The credit travels to the advising bank. Additional content can travel through MT701. **Advising bank authenticates and advises the credit.** The exporter reviews the documentary requirements before shipment. **Amendment becomes necessary.** The importer requests a shipment-date extension and the issuing bank sends MT707. **Exporter ships and presents documents.** The nominated bank examines the documents. **A discrepancy appears.** The relevant bank can communicate the discrepancy through MT750 and seek instructions. **Issuing bank waives the discrepancy.** MT752 can authorize payment, acceptance or negotiation where appropriate. **Reimbursement occurs.** The issuing bank's MT740 reimbursement authority supports the claiming bank's MT742 reimbursement claim where a separate reimbursing bank is involved. **Funds settle through the payments system.** The cash leg follows the applicable ISO 20022 payment route. ## Example: Full Standby Letter of Credit SWIFT Flow Now consider a company required to provide a USD 10 million payment standby to a commercial counterparty. **The applicant requests issuance.** Its bank underwrites the USD 10 million contingent exposure and agrees the collateral and reimbursement arrangement. **The bank issues the standby.** MT760 carries the undertaking through the banking channel, with MT761 continuation where required. **The beneficiary receives the advised standby.** The beneficiary reviews issuer, wording, amount, expiry and drawing conditions. **The instrument requires amendment.** MT767 carries the amendment and MT775 can carry continuation information. **A draw event occurs.** MT765 can carry the demand for payment. **The demand is examined.** Where the demand is refused, MT786 communicates that refusal. **The instrument expires or is released.** Reduction, release or non-extension can generate the relevant MT769 or MT785 communication. ## MT700 Versus MT760 | MT700 | MT760 | | ----------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- | | Documentary credit issuance | Demand guarantee or Standby Letter of Credit issuance | | Usually supports payment against shipping or commercial documents | Usually supports a payment or performance obligation upon specified demand conditions | | Commonly governed by UCP 600 | Standbys often use ISP98; demand guarantees commonly use URDG 758 | | Beneficiary expects ordinary presentation in the course of trade | Drawing commonly follows a specified failure, default or direct-pay event depending on instrument | ## MT700 Versus MT799 MT700 issues a documentary credit through a dedicated structured format. MT799 carries free-format text. A bank cannot convert an MT799 into an MT700 merely by writing “we confirm we will issue an LC” inside the message. Such text might carry commercial significance depending on its wording and authority, but it remains a different communication from the operative documentary credit. ## MT760 Versus MT799 The same distinction applies to Standby Letters of Credit. MT760 carries the actual guarantee or standby issuance structure. MT799 carries free-format communication. Transaction parties should therefore stop evaluating SWIFT codes as interchangeable milestones in a broker-created procedure. ## Common SWIFT Message Myths ### “MT799 Is Proof of Funds” MT799 is free format. Read the text. ### “MT760 Means the Beneficiary Has Received Cash” MT760 concerns issuance of a guarantee or standby undertaking. A cash payment follows a separate settlement process when payment becomes due. ### “MT700 Means the Seller Has Been Paid” MT700 issues the documentary credit. Payment follows compliant presentation and the terms of the credit. ### “MT103 Is Proof That an SBLC Was Monetized” A payment instruction and an SBLC are separate instruments and processes. Establish the commercial and credit relationship linking the two before drawing conclusions. ### “Every Deal Follows MT799 → MT760 → MT103” That sequence has become internet boilerplate. Real transactions use the messages required by their banking structure. A documentary credit may begin directly with MT700\. A guarantee may begin with MT760\. A bank may communicate through MT759 or another dedicated message. Payment follows the relevant settlement route. ### “MT760 Is a Financial Product” MT760 is the message type. The product is the underlying demand guarantee or Standby Letter of Credit. ### “Having a SWIFT Copy Proves the Instrument Is Valid” Bank authentication occurs through banking channels. A PDF, screenshot or broker-forwarded copy gives a third party limited assurance regarding authenticity. The receiving or advising bank should verify the message through the appropriate interbank process. ## SWIFT BICs and Bank Identification SWIFT messages identify participating institutions through Bank Identifier Codes, commonly called BICs. The BIC helps route the message to the relevant institution. It says nothing by itself about the bank's willingness to issue a facility or the creditworthiness of the applicant. Beneficiaries accepting large letters of credit and standbys should separately evaluate the issuing institution where issuer quality affects the transaction. ## RMA and Interbank Messaging Relationships Relationship Management Application controls form part of the SWIFT security framework used by institutions to manage which counterparties can send them certain messages. Operational ability to exchange SWIFT messages therefore depends on more than knowing another bank's BIC. Banks maintain their own relationship controls, compliance processes and correspondent arrangements. ## Confirmation Changes the Credit Risk, Not the MT700 Code A confirmed documentary credit adds the undertaking of the confirming bank. The commercial value can change significantly because the beneficiary gains an additional bank obligation. The underlying documentary credit remains within the Category 7 documentary-credit framework. The beneficiary should look at the confirmation instruction, the confirming bank's actual commitment and the credit terms rather than expecting a magical separate “confirmed LC SWIFT code.” Financely provides dedicated [letter of credit confirmation](https://www.financely-group.com/letterofcredit-confirmation?ref=blog.financely.io) advisory where supplier or country-risk requirements call for an additional bank undertaking. ## Usance Credits, Acceptance and Discounting A usance documentary credit creates payment at an agreed future maturity rather than immediate sight payment. The SWIFT messaging therefore interacts with acceptance, deferred payment and subsequent discounting. An exporter can potentially discount an accepted or otherwise eligible deferred payment obligation with a bank or trade-finance institution. Financely covers these structures through its [usance letter of credit discounting](https://www.financely-group.com/usance-letter-of-credit-discounting-ucp600?ref=blog.financely.io) practice. ## UPAS Letter of Credit Structures UPAS structures separate the seller's payment timing from the buyer's financing tenor. The seller receives payment at sight while the applicant receives deferred payment terms funded through the banking arrangement. The documentary credit wording, nominated bank, reimbursement structure and financing bank all need to align. The SWIFT messages communicate those mechanics, while the underlying credit facility determines who funds the tenor. ## Transferable and Back-to-Back Credits Transferable documentary credits can use MT720 to communicate the transfer. Back-to-back structures follow a different architecture. The first credit supports or facilitates issuance of a separate second documentary credit. The second LC carries its own issuance message and banking relationship. This distinction matters for commodity intermediaries who often use the words transferable, assignable and back-to-back interchangeably even though the legal and operational mechanics differ. ## SWIFT Messages Should Follow the Deal Structure The most efficient way to understand trade-finance SWIFT traffic is to start with the transaction. Ask: - Which bank is issuing? - Which bank is advising? - Is confirmation required? - Where is the credit available? - Who examines the documents? - Who funds or negotiates? - Is there a reimbursing bank? - Is the credit transferable? - Are amendments expected? - What happens after a discrepant presentation? - How will the final payment settle? The message sequence follows from those answers. ## Financely Letter of Credit and Trade Finance Advisory Financely structures documentary credit, Standby Letter of Credit, bank guarantee and wider trade-finance mandates for companies with identifiable commercial transactions. Our work covers facility design, applicant credit preparation, bank selection, documentary-credit wording, confirmation requirements, reimbursement mechanics, supplier acceptance and financing around the instrument. We also work with importers and exporters through our [documentary letter of credit service](https://www.financely-group.com/documentary-letter-of-credit-service?ref=blog.financely.io) and broader [trade finance services for importers and exporters](https://www.financely-group.com/trade-finance-services-for-importers-and-exporters?ref=blog.financely.io). SWIFT messaging comes after the underlying transaction, facility and bank obligations have been structured correctly. ## Structure a Letter of Credit or Trade Finance Facility Financely advises companies arranging documentary credits, confirmed credits, usance facilities, UPAS structures, Standby Letters of Credit, guarantees, reimbursement structures and associated trade-finance facilities. Submit the transaction amount, goods or services, buyer and seller jurisdictions, required instrument, proposed tenor, issuing-bank requirement and available collateral or credit support.
