BIS AT1 Screening: AI for Supervisory Review

Overview

The BIS procedure compares capital rules with AT1 prospectuses, surfaces and ranks possible wording divergences through repeated LLM runs, and preserves paired passages for expert review. The series follows the queue from comparison and AT1 stress cases through governance, testing, security, provider dependence, and re-evaluation. It supports focused supervision, not automated legal judgment.

Learning outcomes

The BIS procedure is most defensible as evidence-linked screening that ranks possible divergences for experts, not as an automated compliance verdict.
Five-run recurrence can prioritize review, but it is conditional on the supplied texts, prompt, model, and consolidation method—not legal significance.
Credit Suisse and Yes Bank show why dormant qualifiers and legacy sequencing terms can matter when stress or rule changes arrive.
Safe adoption requires source lineage, expert-labelled testing, meaningful intervention powers, security, provider continuity, and re-evaluation when conditions change.

FAQ

What does the BIS procedure compare?

It compares applicable capital rules with AT1 prospectuses to find paired provisions whose wording may change a requirement’s scope, conditions, sequence, or consequences; experts interpret the result.

Does the BIS LLM determine AT1 compliance?

No. It produces source-linked candidate divergences and a recurrence signal; supervisory or legal experts decide whether a difference is permitted, material, actionable, or unresolved.

What do the Credit Suisse and Yes Bank cases show?

They show that a PONV qualifier or a legacy sequencing term can become consequential under bank stress or after a regulatory change, while screening still cannot decide the legal outcome.

What controls are needed to use BIS-style AI screening safely?

Safe use needs an authoritative, traceable source pair, bounded purpose, preserved evidence, independent performance testing, real human intervention, security and provider safeguards, and re-evaluation or retirement when conditions change.
