  1. CPMI workstream chair misattributed to wrong central bank

    When AI tools are asked which central bank chairs the CPMI working group behind the harmonised ISO 20022 data requirements, tested AI assistants attributed the role to the Federal Reserve Bank of New York and named a fabricated individual as co-lead — when the Reserve Bank of Australia is confirmed chair and Michele Bullock served as former Co-Chair. For a Legal team at a Payment Institutions firm, this error surfaces in regulatory mapping documents, board briefings, and counterparty submissions that reference the governance pedigree of the harmonised requirements.

    A document filed with a competent authority or shared with a correspondent banking partner that misidentifies the scheme's institutional author requires formal correction and risks signalling to the regulator or counterparty that the firm's Legal function has not engaged with the primary record. In internationally active Payment Institutions where the same briefing template is adapted across corridors, a single AI-originated misattribution can propagate simultaneously into multiple markets before discovery — compounding the remediation burden across jurisdictions.
