Swift ISO 20022 Migration & MX Messaging 1 — Questions and Answers
Question 1: What file format do ISO 20022 MX messages use?
- Plain text (ASCII)
- XML (Extensible Markup Language) (Correct answer)
- JSON (JavaScript Object Notation)
- CSV (Comma-Separated Values)
Correct answer: XML (Extensible Markup Language)
ISO 20022 MX messages use XML (Extensible Markup Language), enabling richer, structured data compared to the ASCII-based MT format.
Question 2: Which SWIFT MT message does the ISO 20022 pacs.008 replace for single customer credit transfers?
- MT 102
- MT 103 (Correct answer)
- MT 202
- MT 940
Correct answer: MT 103
The pacs.008 (FI to FI Customer Credit Transfer) is the ISO 20022 equivalent of the MT 103 single customer credit transfer message.
Question 3: What does 'pacs' stand for in ISO 20022 message naming conventions?
- Payment Authorization and Clearing System
- Payments Clearing and Settlement (Correct answer)
- Payment Account and Credit Service
- Process and Control System
Correct answer: Payments Clearing and Settlement
'pacs' stands for Payments Clearing and Settlement, covering messages used in interbank payment clearing and settlement processes.
Question 4: During the SWIFT ISO 20022 coexistence period for CBPR+, what was permitted on the network?
- Only MX messages could be sent on SWIFT
- Only MT messages could be sent on SWIFT
- Both MT and MX messages could be sent simultaneously on SWIFT (Correct answer)
- Institutions had to permanently select one format at enrollment
Correct answer: Both MT and MX messages could be sent simultaneously on SWIFT
The coexistence period allowed both MT and MX messages to operate simultaneously, giving institutions time to migrate at their own pace without disrupting live traffic.
Question 5: What is the primary advantage of ISO 20022's structured data fields over MT free-form text fields?
- Shorter overall message length
- Improved straight-through processing and higher data quality (Correct answer)
- Lower transmission costs per message
- Faster SWIFT network routing speeds
Correct answer: Improved straight-through processing and higher data quality
Structured data fields in ISO 20022 enable automated processing, reduce manual intervention, and improve data quality compared to unstructured MT free-form fields.
Question 6: Which organization serves as the Registration Authority for the ISO 20022 standard?
- Bank for International Settlements (BIS)
- SWIFT (Correct answer)
- The Federal Reserve
- International Monetary Fund (IMF)
Correct answer: SWIFT
SWIFT acts as the Registration Authority for ISO 20022, responsible for maintaining and publishing the standard's message repository.
Question 7: In what year did SWIFT's Cross-Border Payments and Reporting Plus (CBPR+) ISO 20022 go live for production traffic?
- 2021
- 2022
- 2023 (Correct answer)
