Brazil’s central bank has officially extended its Pix instant payments system to Brazilians living in Argentina, in a move that could accelerate an already dramatic crypto adoption surge across the region.
Banco Central do Brasil announced on March 6 that Brazilians residing in Argentina can now use Pix to pay for goods and services and send money in both countries. For the millions of people who live, work, or travel across the South American border, it means instant, free transfers without the delays, fees, or currency controls that have long made cross-border payments across the region so painful.
The expansion connects two countries with very different economic profiles but increasingly intertwined digital finance ecosystems. Brazil is the largest economy in Latin America. Argentina has spent years managing some of the highest inflation rates in the world. That contrast has made the corridor between them one of the most fertile ground anywhere for fintech adoption.
The Numbers Behind Pix
Pix is not a niche product. Since its launch in November 2020, it has become the dominant payment method in Brazil at a speed that no other instant payment system in the world has matched. Through September 2025, Pix processed 196.2 billion transactions, moving $16 trillion — more than seven times Brazil’s entire annual GDP.
In 2024 alone, Pix processed 64 billion transactions, a 53% jump year over year, surpassing debit and credit card volumes by 80%. By March 2025, Pix volume stood at over 6 billion transactions per month, which is 2.5 times that of credit cards in Brazil.
Over 170 million Brazilians now use Pix, representing 93% of the country’s adult population. Merchants offering Pix as a payment option saw an average 16% revenue increase and 25% customer-base growth within just six months of adoption.
Why Argentina Is the Next Frontier
Argentina is not an obvious candidate for a seamless payments expansion. It has been grappling with triple-digit inflation for years and only recently lifted strict currency controls that prevented residents from freely buying or selling US dollars. But those very pressures have made Argentines some of the most sophisticated digital finance users anywhere.
Argentina ranks as the number one country for crypto adoption per capita in Latin America, while Brazil ranks first in total crypto value received, according to Lemon’s State of the Crypto Industry in Latin America 2025 report. Argentina now has around four times the crypto users it had during the 2021 market cycle, and the Latin America region has roughly three times the adoption rate of the United States.
Pix has already been quietly driving that surge. Argentina recorded 5.4 million crypto app downloads in 2025, with more than 90% corresponding to wallets that had implemented Pix payments in Brazil. The payment rails and the crypto rails, it turns out, are deeply connected.
Inflation, Controls, and the Opening Door
Argentina’s annual inflation rate fell to 37% in 2025 — its lowest in eight years and a threefold reduction from the year before. The government also removed currency controls, allowing residents to freely buy and sell US dollars on the open market for the first time in years.
That liberalization is significant. Before the controls were lifted, the demand for dollar-pegged stablecoins and crypto as inflation hedges was driven partly by necessity. Now, the improvement has opened the door for new crypto use cases beyond savings and cross-border remittances.
Pix’s real-time settlement model also solves a concrete merchant problem in high-inflation environments: in a country like Argentina, waiting days for a credit card payment to settle can visibly erode the real value of a sale. With Pix, merchants receive funds instantly in Argentine pesos.
A Regional Blueprint
The expansion is part of a broader arc. Mobile wallets are now used by 62% of Latin Americans for regular payments, with Argentina at 65% adoption — the highest in the region. Pix is already accepted by Binance Pay, Kraken, Crypto.com, and Mercado Bitcoin for fiat onramping in Brazil. As it spreads beyond Brazil’s borders, the infrastructure connecting traditional instant payments to the crypto economy grows with it.
For the payments industry watching global real-time payment adoption, Brazil’s playbook: mandate participation, make it free, build open standards, and scale up – is increasingly the one everyone wants to copy.
