Brazil central bank to strengthen Pix oversight with 2026 rule changes

The Banco Central do Brasil will implement new Pix regulations in two stages. Starting 10 August 2026, financial institutions will receive more detailed data on the path of each instant transfer, improving the ability to trace funds used in fraud schemes. A second phase begins 1 September 2026, revising the operation of the Special Refund Mechanism (MED) to help victims recover money lost to scams.

These measures aim to increase transparency, speed investigations and enhance cooperation among banks, credit unions and payment firms in combating criminal use of the country's primary instant‑payment system.
