What the RLB Specialist Panel found

9. Which pre-Consumer Duty Dear CEO letters remain in force

Question (paraphrased to protect IP): Which FCA Dear CEO letters remain in force after Consumer Duty implementation? Has the FCA withdrawn any letters that previously set consumer protection expectations?
Source regulation: Consumer Duty (PS22/9 + PRIN 2A), Financial Conduct Authority (Regulator portal: https://www.fca.org.uk)
What AI assistants typically say: Multiple AI tools gave significantly different incorrect responses on this question. One AI stated that the FCA retired approximately 90 Dear CEO letters in April 2025 and over 100 multi-firm and thematic reports in August 2025, presenting these as two separate exercises. A second AI declined to provide any count or list, stating it could not identify verified information from available sources.
What the regulator actually says: From FS25/2 (March 2025): the FCA reviewed all Dear CEO letters pre-dating its 2022–25 strategy and withdrew more than 90 such letters, alongside clearing over 100 old multi-firm reports. These are no longer live supervisory expectations.
Why the AI went wrong: One AI fabricated the dates of both exercises and invented a phased structure that does not reflect the single documented event in March 2025. The other AI failed to identify FS25/2 as the relevant document entirely — the same gap that appears in Finding 6 — demonstrating a consistent blind spot for this specific FCA publication across multiple AI tools. For a Compliance team trying to determine which historic supervisory expectations still bind the firm, neither response is usable.

Impact for Compliance Teams in Retail Banking Sector in the United Kingdom working with the Consumer Duty (PS22/9 + PRIN 2A)

Retail Banking compliance teams meeting on the FCA's withdrawn-letter landscape need a clean account; the model's repeated April/August 2025 timeline across two questions strongly suggests the AI's internal representation is fabricated, and any compliance brief that imports it will be wrong in two places, not one.
