BCRA Tightens Fintech Oversight in Argentina

The BCRA’s Communication B 13208/2026, published in the Official Gazette on July 27, 2026, clarifies services and procedures tied to the regime for financial institutions and payment service providers, or PSPs. The text reinforces the requirement that information and authorization requests be routed through the Central Bank’s formal and digital channels, in line with stricter supervision based on standardized, traceable information across the financial ecosystem.

Argentina: More traceability for institutions and PSPs

In the local market, that regulatory clarification is being paired with the rollout of artificial intelligence systems by banks and fintech companies to detect fraud in real time and share alerts with the BCRA and other players in the system, according to an Ecos365 report published on July 28, 2026. The advanced monitoring effort is described as part of the technology response needed to meet tighter oversight demands and reduce levels of digital fraud.

The Ecos365 report also says those detection and alert capabilities are already part of operational discussions among banks and fintech firms, in a context where the regulator is demanding greater traceability over the filings and information it receives.

Mexico: New obligations and an anti-fraud agenda

In Mexico, the available material points to a tougher compliance agenda. An update to the regulations under the Anti-Money Laundering Law in July 2026 added new compliance obligations, while other background coverage refers to changes linked to the Anti-Money Laundering Law and to the challenges facing digital banking in the country.

At the same time, an Infobae article on digital fraud said Mexico’s financial industry is agreeing to merge cybersecurity and anti-fraud agendas to better shield users from digital fraud. That coverage mentions the involvement of regulatory bodies, but it does not spell out any new concrete rules from CNBV or Banxico.

Along the same lines, an opinion column in El Financiero said Mexican authorities and the financial industry are strengthening their strategies against fraud and cyberattacks, although it also does not mention any specific new regulatory measures from CNBV or Banxico in July 2026.

A tighter focus on monitoring and compliance

The regional picture shows two parallel moves. In Argentina, the BCRA is pushing for formal traceability in filings and authorizations for financial entities and PSPs, while the financial system adopts AI to monitor and respond to fraud. In Mexico, the updated anti-money laundering rules strengthen compliance obligations, and the financial sector is driving a convergence between cybersecurity and anti-fraud.

What is not present in the available material are recent, explicit technical circulars from CNBV or Banxico on banking cybersecurity. What does appear, instead, are clear signs of stronger regulatory and operational pressure on automated monitoring, traceability and supervision in both markets.
