How it began
Members of the central bank team say the system existed in concept from 2016. In December of that year the president of the Banco Central do Brasil, Ilan Goldfajn, signaled that the bank was preparing such a tool. In May 2018 he set up an internal working group on instant payments to write the basic specifications. The name and logo were created inside the bank in February 2020, and Pix was launched in November 2020.
Before it existed
Pix was created to reduce the use of cash and to offer an alternative to the existing ways of paying. These were bank slips known as boletos, cash machines, and the older bank transfer systems called TED and DOC. Transfers through those systems were tied to banking hours, while Pix runs at night, on weekends and on holidays.
How it works
A payer needs only the receiver's Pix key, an alias that identifies the receiving account. For a person the key can be a tax number, an e-mail address, a cell phone number or a random code. A company uses its company tax number. A key can be turned into a static or dynamic QR code. The central bank operates a directory that links keys to accounts and a single settlement system, so funds reach the receiver within a few seconds. Transfers between individuals are free.
Who pushed back
The system has drawn attacks and foreign pressure. In July 2025 a cyberattack on a software company connected to the system led to the theft of more than 540 million reais. In the same month the United States Trade Representative opened an investigation covering Brazil's electronic payment services. Members of the Brazilian government said the inquiry was driven by lobbying from American card companies and technology firms.
What changed first
More than 62 percent of Brazil's population adopted Pix within a year of launch. By 2023 it had overtaken card transactions, with 42 billion transactions in the year. By the end of 2024 it accounted for 47 percent of financial transactions in Brazil. An International Monetary Fund paper described it as a successful instant payment system.
