The US is using trade tariffs to challenge Brazil's state-run Pix payment system even as dollar stablecoins already dominate the country's digital economy.
The US will impose a 25% tariff on most Brazilian imports starting July 22, targeting the country's state-run Pix instant-payment system in the first trade action of its kind against a foreign digital payments network.
"Today's action is necessary to address these unfair trade practices to ensure American workers and companies can compete on a level playing field," Ambassador Jamieson Greer, the US Trade Representative, said in a statement.
The Section 301 investigation cited Pix's mandatory free service for individuals and capped merchant fees as disadvantaging US payment firms Visa and Mastercard. Pix processed nearly 7 billion transactions worth about R$3 trillion ($590 billion) in June alone, and handled 42.9 billion transactions in the second half of 2025 versus 23.8 billion across credit, debit and prepaid cards, according to central bank data.
The action creates a precedent for using trade policy to target foreign digital payment infrastructure, potentially extending to India's Unified Payments Interface and the European Central Bank's planned digital euro, according to the Atlantic Council. A separate Section 301 probe into forced labor could add a 12.5% tariff on Brazil by July 24, bringing the total burden to 37.5%.
Dollar Stablecoins Already Dominate Brazil's Crypto Economy
The irony of Washington's move is that the US dollar already circulates widely in Brazil's digital economy through blockchain-based payment rails. Dollar-linked stablecoins account for roughly 90% of Brazil's crypto transaction volume, most of it used for payments and settlement, according to tax authority data. Brazil processes between $6 billion and $8 billion in crypto each month, much of it using dollar-denominated stablecoins rather than the real.
"Pix has addressed domestic instant payments well, while stablecoins expand what is possible by operating on blockchain networks," Rodrigo Caggiano, founder of Brazilian real-world asset monitoring platform RWA Monitor, said. "In practice, they are complementary."
Brazil's Central Bank Cracks Down on Stablecoins
Even as dollar stablecoins have proliferated, Brazil's central bank has moved to limit their role in regulated cross-border payments. Resolution 561, effective Oct. 1, bars payment firms from settling cross-border transactions in stablecoins or other crypto, closing a back-end channel that had routed reais through dollar tokens. The central bank has described stablecoins as a threat to monetary sovereignty, tax enforcement and anti-money laundering controls.
Pix now faces pressure from both sides: Washington has labeled it a trade barrier, while Brazilian regulators shield it from competition from dollar-backed stablecoins. US pressure is likely to accelerate Brazil's regulatory debate on stablecoins and digital financial infrastructure, Caggiano said, as the central bank builds its own tokenized-settlement system, Drex, on similar programmable rails.
Brazilian President Luiz Inacio Lula da Silva called the US decision unjustified and said Brazil would immediately begin proceedings under its "Reciprocity Law" and revisit the matter within the WTO dispute settlement framework. The US recorded a $14.4 billion trade surplus with Brazil last year, up 112.8% from the prior year, weakening any argument that the tariffs are intended to close a bilateral trade imbalance.
