MT700 Field 57 and Its Relationship with UCP 600 Articles

Introduction

SWIFT MT700 Field 57 identifies the "Advise Through" bank — the intermediary institution that forwards the documentary credit from the issuing bank to the advising bank. This field's relationship with UCP 600 articles, particularly those governing the advising function and bank undertakings, is essential for ensuring the credit reaches the correct party with proper authorization.

Failure Modes

1. Field 57 Routes Credit Through Bank Not Capable of Advising Under Article 9(a)
If Field 57 names a bank that lacks the operational capability or correspondent relationship to forward the credit, the Article 9(a) requirement for a "bank capable of doing so" is not met.

2. Field 57 Contradicts Article 9(b) Authenticity Signification
When the credit passes through a Field 57 intermediary that cannot verify the issuing bank's authentication, the advising bank downstream cannot satisfy the Article 9(b) requirement to signify satisfaction with the credit's authenticity.

3. Field 57 Creates a Transmission Gap Violating Article 11
If the Field 57 bank fails to forward the credit or introduces a delay, the teletransmission chain contemplated by Article 11 is broken, potentially affecting the credit's effective date.

4. Field 57/Article 10 Amendment Routing Failure
When the credit is amended via MT707, the amendment must follow the same routing path as the original MT700. If Field 57 was used for the original but the amendment is sent directly to the advising bank, the intermediary bank may not receive the amendment, creating inconsistencies.

Resolution Steps

1. Verify that the Field 57 bank meets the Article 9(a) capability requirement by confirming its SWIFT connectivity, correspondent relationships, and trade finance operational capacity.

2. Confirm that the Field 57 bank can support Article 9(b) authenticity verification by checking whether it has a key-customer or other authentication arrangement with the issuing bank.

3. Ensure MT707 amendments follow the same Field 57 routing as the original MT700. Establish a procedural checklist for amendment routing.

4. When Field 57 is used, confirm with the advising bank that it expects to receive the credit through the specified intermediary. Misaligned expectations create processing delays.

5. Map the complete transmission path from issuing bank through Field 57 to advising bank, and validate each link in the chain before transmitting the MT700.

6. Document the Field 57 routing decision in the credit file, including the rationale for selecting the specific intermediary bank.

7. Monitor the Field 57 bank's performance over time. Recurring delays or errors may indicate that the bank should be replaced in future transactions.

Conclusion

Field 57's relationship with UCP 600 Articles 9 and 11 is operationally significant. The field determines whether the credit's transmission chain is valid, whether authenticity can be verified, and whether amendments will reach all parties in the chain. Banks that treat Field 57 as a routing formality rather than a substantive element of the UCP framework risk transmission failures with legal and financial consequences.

Frequently Asked Questions

Q1: Does UCP 600 require the use of Field 57?
No. UCP 600 does not mandate a specific SWIFT field for intermediary routing. Field 57 is a SWIFT convention, not a UCP requirement.

Q2: Can Field 57 name a non-bank entity?
SWIFT rules restrict Field 57 to BIC-registered financial institutions. Non-bank entities cannot be named in Field 57.

Q3: How does Field 57 affect the advising bank's obligations under UCP Article 9?
Field 57 does not alter the advising bank's obligations. However, the routing through Field 57 affects the advising bank's ability to verify authenticity under Article 9(b).

Q4: What should happen if the Field 57 bank goes offline or becomes insolvent?
The issuing bank should send an MT799 notifying the advising bank of the situation and request that the credit be considered as transmitted directly, or issue a new MT707 with an updated Field 57.

Q5: Can Field 57 be blank in an MT707 amendment?
Yes. If the original MT700 used Field 57 but the amendment does not, the amendment will be sent directly to the advising bank, potentially bypassing the original intermediary. This inconsistency should be avoided.
