Overview

Pix (Portuguese pronunciation: [ˈpiks]) is an instant payment platform created and managed by the Central Bank of Brazil (BCB). It enables free instant transfers between individuals in Brazilian real 24 hours a day without interruption, even outside banking hours and during holidays or weekends; payments made and received by legal entities may be subject to fees.

Launched in November 2020, Pix was adopted by over 62% of Brazil's population within a year; by 2023, it overtook card transactions. By the first quarter of 2026, monthly Pix transactions reached almost R$3.4 trillion (approximately US$660 billion), a transaction volume equivalent to roughly one-quarter of the annual Brazilian GDP.

Pix is the largest payment method in Brazil, processing 8.6 times more transaction value than credit and debit cards combined. The system has seen widespread adoption, with 200 million monthly active users (80% of the population) comprising 175 million individuals and 25 million institutions.

Etymology

Pix is not an acronym. The goal of the Central Bank at the time of its implementation was to associate the system with technology. One suggested name was "Pi" (for "Pagamentos Instantâneos", lit. 'Instant Payments'), and another was "Tix" (for "Transações instantâneas X", lit. 'Instant Transactions'); the chosen solution was to blend the two proposals, which led to the creation of "Pix".

The x in the name is meant to represent multiplication or a mathematical variable, symbolizing the "various possible uses" of Pix, such as payments between individuals, businesses, and the government, among others. Some sources also relate the name Pix to the concept of a pixel, which is said to be reflected in the logo design.

History and usage

Members of the team responsible for Pix state that the system had already existed "in concept" since 2016; in December of that year, the then-president of the Central Bank, Ilan Goldfajn, signaled that the institution was preparing to launch a tool inspired by Zelle, which had been announced shortly before in the United States. Still that year, Central Bank staff had produced a report titled "Fast payments – Enhancing the speed and availability of retail payments" on the benefits and design of instant payment systems.

The Central Bank's technical team concluded that implementing such an instant payment system would be "excellent" policy; the proposal was submitted to the board of directors for review and was eventually approved. In May 2018, during Michel Temer's administration, Goldfajn created an internal working group called "Pagamentos Instantâneos" to develop the basic specifications of what would later become Pix.

The project was carried forward by Roberto Campos Neto during Jair Bolsonaro's administration. The "Pix" brand name and logo were created in-house by the BCB in February 2020. In November 2020, the system was finally launched.

The Central Bank of Brazil launched Pix in part to spur competition in the country's banking industry. Bloomberg referred to the system as "ubiquitous" in Brazil in October 2021, a year after Pix's release. In November 2021, it was reported that the system had already made more than 6 billion transactions, totaling an amount of R$3.75 trillion (about US$682 billion). In 2023, Pix was the main payment system in Brazil, totaling 42 billion transactions.

United States government investigation

In July 2025, the Office of the United States Trade Representative (USTR) launched an investigation into unfair trading practices by Brazil, focusing on electronic payment services, preferential tariffs, and anti-corruption interference. Among the reasons for the investigation, potential unfair advantaging of Brazilian payment services over US competitors was cited. This appeared to target Pix. Brazilian President Luiz Inácio Lula da Silva has accused U.S. president Donald Trump of being "bothered by Pix" because it "will put an end to credit cards".

Lula da Silva's administration has planned to launch a "massive" media campaign in defense of Pix, with the slogan "O Pix é do Brasil" [The Pix is Brazil's], in an effort to associate the system with national sovereignty.

Members of the Brazilian government accuse the investigation of being born of lobbying by U.S. credit card companies and big tech firms. Economist Paul Krugman accused the U.S. of being pressured by the financial sector into the investigation. According to Fundação Getulio Vargas Finance professor Fabio Gallo, Pix is inspiring other countries to develop their own solutions, thereby weakening the dollar and threatening the "end of the Western financial monopoly", in which the U.S. is no longer able to track, tax, or block transactions.

On 15 July 2026, following the conclusion of the USTR investigation, the Trump administration imposed 25% tariffs on a range of Brazilian imports. Furthermore, proposed alterations (flexibilização) to the system in response to United States pressure have faced significant opposition. A survey conducted before the imposition of tariffs found that 72% of the population favored maintaining the current system without changes, despite the threat of U.S. tariffs.

Features

The Brazilian instant payment ecosystem (Pix) was created with the aim of reducing cash transactions and offering an alternative to existing payment instruments, such as bank slip or boleto and ATM, as well as being faster and more affordable. The main advantages of Pix are its full-time availability, the speed of transactions using the system, low-cost functionality, convenience, versatility, open environment, and safety.
