Content of Division 4 of Part VI of MAS Notice 637

What the RLB Specialist Panel found

5. Content of Division 4 of Part VI of MAS Notice 637

  • 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 Incorporated in Singapore (Regulator portal: https://www.mas.gov.sg)
  • What AI assistants typically say: AI tools describe Division 4 of Part VI as covering submission requirements relating to capital instruments, while explicitly noting in the same response that the divisional structure could not be exhaustively verified from publicly available sources.
  • What the regulator actually says: No regulator excerpt was available for this finding. Practitioners should consult the consolidated MAS Notice 637 directly to confirm the content of Division 4 of Part VI.
  • Why the AI went wrong: The AI inferred the content of Division 4 from the general subject matter of Part VI — which relates to capital definitions and instruments — rather than retrieving the actual divisional structure of the notice. The AI's own caveat acknowledges verification was not possible, yet the response still led with a substantive characterisation. Presenting an unverified inference as a primary answer, with the uncertainty buried in a trailing note, creates a material risk that a practitioner will treat the answer as reliable.

Impact for this audience

A Lawyer asked to advise on what submission obligations or capital instrument conditions apply under a specific division of Part VI of MAS Notice 637 who uses the AI's characterisation as a starting point may frame their research and advice around the wrong subject matter entirely. Part VI's divisional structure in the current consolidated notice may not match the AI's inference from general capital-definition subject matter, meaning the Lawyer could scope the client's obligations incorrectly from the outset. Where the advice influences a capital instrument issuance, regulatory submission, or capital planning decision, the error carries direct financial and compliance consequences for the client and professional risk for the advising Lawyer.
