Unverified characterisation of Division 4 of Part VI

What the RLB Specialist Panel found

5. Unverified characterisation of Division 4 of Part VI

  • Question (paraphrased to protect IP): What does Division 4 of Part VI of MAS Notice 637 cover?
  • Source regulation: MAS Notice 637 (Risk Based Capital Adequacy Requirements for Banks) — Monetary Authority of Singapore (Regulator portal: https://www.mas.gov.sg)
  • What AI assistants typically say: AI tools characterised Division 4 of Part VI as covering submission requirements relating to capital instruments, while explicitly acknowledging in a caveat that the divisional structure of Part VI in the current version of the Notice could not be exhaustively verified from publicly indexed sources alone.
  • What the regulator actually says: No regulator excerpt was available for direct quotation in this finding; the actual subject matter of Division 4 of Part VI should be verified by reference to the consolidated MAS Notice 637 text available via the MAS regulatory portal.
  • Why the AI went wrong: The AI inferred the content of Division 4 from the general subject matter of Part VI (capital definitions and related requirements) rather than retrieving the actual divisional headings or text. Its own hedge flagged that the inference was unverified, yet the response still presented the characterisation as primary. A reader who acts on the headline answer without reading the caveat will carry an unconfirmed regulatory characterisation into their work.

Impact for this audience

A Compliance team advising on capital instrument eligibility — for example, reviewing whether a proposed Tier 2 instrument meets MAS requirements, or preparing documentation for a capital instrument issuance — would look to Part VI and its divisions to confirm the applicable requirements. If Division 4 does not in fact cover capital instrument submission requirements as the AI suggested, any internal guidance or board paper built on that characterisation would misstate the regulatory basis. For capital instrument transactions, which require MAS engagement and may involve public disclosure, a misstatement of the applicable regulatory framework creates both a supervisory risk and a reputational risk if the error becomes apparent to counterparties or investors.
