US hits Brazil with 25% tariffs over Pix payment system dispute

The Trump administration imposed 25% tariffs on most Brazilian imports Wednesday, citing Brazil's government-run Pix instant-payment system as an unfair trade barrier that disadvantages US card networks Visa and Mastercard.

"These tariffs could have a much broader impact on payments than people realize, particularly if Brazil's Pix system is part of what the US is targeting," said Teymour Farman-Farmaian, co-founder and CEO of cross-border payment firm Higlobe.

The tariffs, effective July 22 under Section 301 of the Trade Act of 1974, follow a yearlong USTR investigation that determined Brazilian measures related to digital trade and electronic payment services are "unreasonable." Pix, launched by Brazil's central bank in 2020, now accounts for more than half of all transactions in the country by volume and has about 170 million users, or 80 percent of the population. The system processed an estimated $25.2 billion in its first year and is on pace to surpass $187 billion in 2026, according to Brazilian fintech EBANX.

The dispute threatens to disrupt a major flow of funds and deepen a geopolitical rift. Brazil has threatened retaliation, and President Luiz Inácio Lula da Silva has vowed to defend Pix, calling it "a heritage of our people." The clash also risks pushing Brazil toward deeper economic ties with China, Farman-Farmaian warned, as the US seeks to protect the decades-long dominance of its card networks in global payments.

Pix's Rise Reshaped Brazil's Financial Landscape

Pix has become the most popular online payment method in Brazil, covering 42 percent of e-commerce purchases in 2025 versus 41 percent for credit cards, EBANX data shows. By 2028, Pix is on pace to reach 50 percent of e-commerce payments compared with 36 percent for credit cards. The system has brought more than 70 million Brazilians into the financial system, though card transaction volumes have continued to rise in absolute terms.

Credit cards' share of transactions has fallen to about 15 percent from roughly 20 percent before Pix's launch, while debit cards dropped to about 10 percent from about 26 percent. Micro-businesses account for 79 percent of the companies that paid with instant transfer on EBANX merchants, and 48 percent of them identify as individual entrepreneurs.

Brazil's central bank has signed agreements to share information about Pix with 65 international counterparts, from Germany and Canada to South Africa and Turkey, signaling the model's global appeal. Central bank chief Gabriel Galipolo dismissed complaints about Pix's impact on card revenues, arguing the number of credit card users had increased in absolute terms because Pix pushed Brazilians to open bank accounts. "It would be kind of like saying that creating basic sanitation hurt the revenues of those who own water trucks," he said.

A Broader Geopolitical Gamble

The USTR investigation found Pix "unfairly disadvantaged US companies," echoing complaints from Visa and Mastercard that Brazil's government subsidizes Pix by covering payment fees that foreign card networks charge. The Information Technology Industry Council, a Washington trade group representing Visa, Mastercard and Meta, has urged USTR for several years to level the playing field for its members in Brazil.

Yet the tariffs may not directly affect Pix's operations. "Tariffs and payment systems operate on different layers of the economy, so we would not expect US trade policies to have a direct impact on how Pix operates," said Sebastian Fantini, global product director at EBANX. "Pix is a domestic financial infrastructure regulated by the Central Bank of Brazil, while tariffs affect the movement and pricing of goods across borders."

The political stakes are high. Brazilian President Lula blamed the tariffs on Senator Flávio Bolsonaro, a candidate for president and son of former President Jair Bolsonaro, a Trump ally. Secretary of State Marco Rubio said Lula "put his own ego ahead of making a deal." Lula responded on social media: "No one is going to change our Pix. It's public, it's free, and it will stay that way."

The last major US tariff escalation under Section 301 — the 2018-2019 trade war with China — affected more than $350 billion in bilateral trade and triggered a 15 percent decline in Chinese imports from the US over two years (Census Bureau). Brazil's case is smaller in scale but carries a novel dimension: the weaponization of trade policy to challenge another country's domestic payment infrastructure. If the US succeeds in pressuring Brazil over Pix, it could set a precedent for similar actions against other government-backed payment systems, including India's UPI, which has also drawn scrutiny from American card networks.
