BCRA and Banxico adjust fraud rules

Update September 28, 2026: the reference tied to Communication A 8471/2026 is now posted on Argentina’s official rules site as norm 429545. The rest remains unchanged, the BCRA added fraud management to operational risk, and Banxico is still keeping its public consultation open.

The Central Bank of the Republic of Argentina has added fraud risk management to its operational risk framework, according to a communication cited by El Cronista as Communication A 8471/2026. The same source says the framework sets guidelines for identifying, assessing, monitoring, controlling, and mitigating that risk for financial institutions and certain payment service providers. In parallel, Banco de México is still running a public consultation on Annex 5 of a draft rule set for clearinghouses linked to card payments.

What scope would the BCRA measure have?

According to El Cronista, the communication would fold fraud into the operational risk framework and apply to financial institutions and certain PSPs. The publication also says the guidelines are meant to organize how organizations identify, assess, track, control, and mitigate that risk.

The same material assigns two effective-date schedules to Communication A 8471/2026. For financial institutions, the date would be December 1, 2026. For certain PSPs, the phased rollout would run through September 2027.

The regulatory reference tied to that communication is already published on Argentina’s official rules site as norm 429545, according to Argentina.gob.ar.

What is known about Banxico’s consultation?

Banco de México is keeping a prior public consultation open before issuing Annex 5 of the draft rules for the organization, operation, and functioning of clearinghouses for card payments. The item under review concerns the exchange of financial transaction messages.

The available information does not yet detail the final text of the annex or allow a conclusion that the project has already been approved. For that reason, the confirmed point on Banxico’s site is the existence of the public consultation and the specific subject still under review.

Are there any confirmed CNBV and Nubank Mexico updates?

There is no verifiable recent update from the CNBV in the material provided. What does appear is a Nubank Mexico post claiming that the Single Banking Circular contains provisions on information security, the appointment of a responsible officer, incident reporting to the CNBV, and biometric validation in certain transactions.

That post, however, is not a new regulatory requirement and was not checked against the official text. As a result, it should be read as a statement from the bank on its blog, not as a confirmed obligation in this report.
