I. Common Risks in Using MT199
1. Ambiguity and Misinterpretation
MT199 is free-format, allowing flexibility in narrative (Field 79), but this also creates a risk of unclear instructions or misread intentions.
Impact: Misinterpretation can delay transactions, trigger unnecessary queries, or cause operational errors.
Mitigation: Use concise, structured language and clearly reference transaction IDs, dates, and counterparties.
2. Fraud and Unauthorized Messaging
Fraudsters may attempt to forge or manipulate MT199 messages to deceive counterparties, especially in cross-border transactions.
Impact: Could lead to financial loss or reputational damage.
Mitigation: Always verify sender credentials through SWIFT Relationship Management Application (RMA) and contact the sending institution for confirmation when necessary.
3. Compliance and Regulatory Risks
Improper MT199 usage can result in violations of AML (Anti-Money Laundering), KYC (Know Your Customer), or sanctions regulations.
Impact: Non-compliance may incur penalties, legal action, or regulatory scrutiny.
Mitigation: Integrate MT199 oversight into internal compliance frameworks and maintain audit logs for all messages.
4. Delayed or Misrouted Communication
Incorrect addressing or omission of SWIFT BIC codes can delay delivery or route the message to the wrong department.
Impact: Causes operational inefficiencies and potential missed deadlines.
Mitigation: Follow bank routing protocols and double-check recipient BIC codes before sending.
5. Confidentiality Breach
MT199 often contains sensitive transaction information, making it critical to ensure proper access controls.
Impact: Unauthorized disclosure may compromise transaction integrity or client trust.
Mitigation: Limit access to authorized personnel and avoid including unnecessary sensitive details in free-format narratives.
II. Best Practices for MT199 Usage
1. Maintain Message Clarity
-
Use structured sentences with clear references to transaction IDs, dates, and counterparties.
-
Avoid ambiguous terms and unnecessary jargon.
Example:
“This MT199 is sent to confirm receipt of MT103 reference 123456 dated 10-Oct-2025. No further action required at this stage.”
2. Implement Fraud Prevention Measures
-
Verify sender and recipient banks via SWIFT RMA.
-
Be vigilant for unusual requests or outside-the-network messages.
-
Cross-check message content against known transaction records.
3. Ensure Compliance with Regulations
-
Screen counterparties for sanctions, PEP status, and AML risk.
-
Document all MT199 exchanges for internal audits.
-
Include internal disclaimers if necessary to clarify informational purpose.
4. Use Proper Routing and Timing
-
Confirm correct SWIFT BIC codes and internal routing before sending.
-
Schedule messages to allow timely processing by the receiving institution.
-
Track delivery status and escalate if delays occur.
5. Protect Confidentiality
-
Restrict access to sensitive messages within the bank.
-
Avoid unnecessary disclosure of financial amounts or client information.
-
Use secure internal platforms when drafting or storing MT199 content.

| Fraud/Unauthorized Use | Forged or manipulated messages | Verify via SWIFT RMA, confirm sender |
| Compliance Breach | AML/KYC/sanctions violations | Integrate MT199 oversight, maintain audit logs |
| Misrouting or Delay | Wrong recipient or delayed processing | Double-check BIC codes and routing |
| Confidentiality Breach | Sensitive info exposed | Restrict access, avoid unnecessary details |
IV. Conclusion
MT199 is a powerful and flexible SWIFT tool for interbank communication, but its free-format nature requires careful management.
By ensuring clarity, verifying sources, following compliance protocols, and protecting confidentiality, financial institutions can minimize risk and maintain efficient, secure communication channels.
