BCRA updates SINAP Circular 1-248

The Central Bank of the Argentine Republic published Communication A 8438/2026, amending Circular SINAP 1-248 on the National Payments System, checks and other compensable instruments. The update, issued on August 13, 2026 in the Official Gazette, includes replacement pages for financial institutions and other nonfinancial credit providers, and updates the applicable consolidated text.

What changes with Communication A 8438?

The communication updates the regulatory compilation for the National Payments System and reorganizes Circular SINAP 1-248, with no new cybersecurity technical requirements appearing in the public documentation reviewed. According to the official material, the adjustment focuses on the operating and reporting framework that governs checks and other compensable instruments.

The Official Gazette, in the notice linked to the rule, also says that part of the related technical and regulatory documentation can be consulted in the BCRA's Prebisch Library and in the Legal and Regulatory Framework section of the Central Bank website. That setup reinforces that this is primarily a regulatory compilation update and a documentation access change.

Who does it affect, and what is the operational impact?

The measure is aimed at financial institutions and other nonfinancial credit providers, since they are the entities covered by Circular SINAP 1-248 within the National Payments System. In practice, the change affects the operating and reporting framework those entities follow for the clearing of checks and other instruments included in the circular.

In the public documentation reviewed, no new specific technical requirements for banks or changes to cybersecurity standards are described. The focus instead remains on updating the consolidated text and making the normative references available through the BCRA's official channels.

What do regional compliance references say?

In Mexico, the Mexican Stock Exchange follows a different regulatory update framework based on CNBV general provisions. According to its Maintenance Information pages, Article 28 sets minimum requirements to remain listed, the review is annual, and the result is reported to the Commission in June, in addition to being made public.

The BMV also notes that, when an issuer has compliance issues, it may request corrective programs under Article 29. That mechanism adds regulatory oversight and remediation, but the pages reviewed do not mention any recent specific changes in banking cybersecurity controls or standards.

The English version of the Listing and Maintenance section of the BMV Group repeats that same framework of annual review, reporting to the authority, and public disclosure. In the material reviewed, both countries show formal compliance and regulatory update moves, although without specific new developments in banking cybersecurity.
