Argentina's BCRA Tightens Digital Filings

The Central Bank of the Argentine Republic published Communication B 13208/2026 on July 27, 2026, and ordered financial entities and payment service providers to route filings and requests through the institution's formal digital channels.

The measure reinforces the obligation to submit information and authorization requests through official channels, as part of a tighter supervisory framework based on standardized, traceable information for Argentina's financial ecosystem. The notice was published in the Official Gazette on July 29, 2026.

BCRA regulatory update

At the same time, Communication A 8457/2026 appears in the Official Gazette as a formal update to the compiled text of the "Principles for Financial Market Infrastructures." According to that publication, previously provided pages are being replaced and the body of rules applicable to Argentina's financial market infrastructures is being consolidated.

That scope underscores that the rule directly affects entities operating payment and settlement systems under BCRA oversight. The official reference places the update in the Official Gazette of July 29, 2026.

Mexico: shared agenda against digital fraud
