Content of Division 4, Part VI of MAS Notice 637

What the RLB Specialist Panel found

4. Content of Division 4, 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 (consolidated) (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 of Part VI could not be exhaustively verified from publicly indexed sources alone.
What the regulator actually says: Part VI of MAS Notice 637 addresses capital definitions and related requirements. The precise scope of each division within Part VI — including Division 4 — must be confirmed from the text of the consolidated Notice, as the divisional structure is not reliably reproduced in publicly available summaries or secondary sources.
Why the AI went wrong: The AI inferred the likely content of Division 4 from its general understanding of what Part VI addresses, rather than retrieving the verified divisional breakdown. It then acknowledged this uncertainty within the same response — a pattern where a plausible characterisation is offered alongside a hedge that, in practice, many readers will discount. A Compliance team acting on the substantive claim without reading the hedge would work from an unverified description of a specific regulatory provision.

Impact for Compliance Teams in Corporate Banking Sector in Singapore working with the AI Hallucinations Affecting Compliance at Corporate Banking Firms in Singapore

A Compliance team that relies on the AI's unverified description of Division 4 of Part VI as covering capital instrument submission requirements may draft internal policies or board-level capital reporting frameworks around an incorrect understanding of what that Division actually requires. If the Division's true content is different — or if the divisional structure of Part VI in the current consolidated Notice differs from what the AI inferred — every downstream work-product built on that description contains a structural error.

For a Corporate Banking firm, a mischaracterised capital reporting or instrument submission obligation could result in regulatory non-compliance with Part VI requirements, potentially attracting MAS supervisory action and requiring a full review and correction of affected internal frameworks at significant cost.
