MT700 Field 58 and Its Relationship with UCP 600 Articles

Introduction

SWIFT MT700 Field 58 identifies the confirming bank — the institution that adds its irrevocable undertaking to a documentary credit. This field operates within the framework established by UCP 600 articles that govern confirmation, nomination, and bank undertakings. Understanding how Field 58 connects to these articles is essential for ensuring that the confirmation arrangement is legally sound and operationally effective.

Failure Modes

1. Field 58 Names a Bank That Cannot Add Confirmation Under Article 8(b)
If the bank named in Field 58 has not been authorized by the issuing bank or has declined to confirm, the Article 8(b) condition for adding confirmation is not met. The Field 58 designation becomes inoperative.

2. Field 58 Contradicts Article 8(d) Non-Confirmation Obligation
When the bank named in Field 58 is not empowered to add confirmation and fails to inform the issuing bank as required by Article 8(d), the credit's confirmation status remains ambiguous.

3. Field 58/Article 8(c) Timing Mismatch
Article 8(c) states that a confirmation is binding from the moment it is added. If Field 58 identifies a bank that adds confirmation after documents have been presented, the timing creates confusion about whether the confirmation covered the presentation.

4. Field 58 Names a Bank That Cannot Process Reimbursement Under Article 13
If Field 58 names a confirming bank that has no reimbursement arrangement (Field 53 or otherwise), the bank's Article 8 undertaking is impaired because it cannot fulfill its payment obligation.

Resolution Steps

1. Confirm that the Field 58 bank has accepted the confirmation mandate before transmitting the MT700. A pre-confirmation communication with the bank prevents Field 58 designation errors.

2. Align Field 58 with Article 8(b) authorization requirements by verifying that either the issuing bank or a nominated bank has requested the confirmation.

3. When Field 58 is populated, verify that the confirming bank has a functional reimbursement arrangement through Field 53 or direct agreement with the issuing bank.

4. Track the timing of confirmation relative to the MT700 transmission and document presentation. Ensure Article 8(c) timing obligations are met.

5. If the Field 58 bank cannot confirm, request an MT707 amendment to remove Field 58 and notify the beneficiary that the credit is unconfirmed.

6. Include Article 8 compliance checks in your confirmation workflow, covering authorization, timing, and reimbursement.

7. Maintain a confirmation register that tracks Field 58 designations, confirmation status, and Article 8 compliance for each documentary credit.

Conclusion

Field 58 is the SWIFT mechanism that activates UCP 600 Article 8's confirmation provisions. Its accuracy determines whether the confirming bank's irrevocable undertaking is properly established. Banks must treat Field 58 as a substantive legal element, not a routine routing field.

Frequently Asked Questions

Q1: Can Field 58 be added after the MT700 is transmitted?
Yes, through an MT707 amendment. The amendment adds the confirmation and must be accepted by the confirming bank per Article 10.

Q2: Does Field 58 override Field 53 on reimbursement matters?
No. Field 58 identifies the confirming bank, while Field 53 identifies the reimbursing bank. They are separate but interconnected elements of the payment chain.

Q3: What if Field 58 names a bank that later becomes insolvent?
Under Article 8(a), the confirming bank's undertaking is irrevocable once added. If the bank becomes insolvent, the beneficiary may lose the benefit of the confirmation. This is a credit risk that Field 58 alone cannot prevent.

Q4: Can Field 58 and Field 52A (Issuing Bank) name the same bank?
This would create a self-confirming credit, which is permissible under UCP 600 but unusual in practice.

Q5: How does Field 58 interact with transferable credits under Article 38?
When a confirmed credit is transferred under Article 38, the confirmation may or may not transfer to the second beneficiary, depending on the credit terms. Field 58 in the original MT700 does not automatically apply to the transferred credit.
