Dollar-linked stablecoins already account for roughly 90% of crypto transaction volume in Brazil, 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 instead of the country’s own currency.
However, even as dollar stablecoins have proliferated, Brazil’s central bank has moved to limit their role in regulated cross-border payments. Resolution 561, effective October 1, is set to bar payment firms from settling cross-border payments in stablecoins or other crypto, closing a back-end channel that had routed reais through dollar tokens. The central bank has cast stablecoins as a threat to monetary sovereignty, tax enforcement and anti-money laundering controls.
Pix now faces pressure from both sides after Washington named it a trade barrier, while Brazilian regulators shield it from growing competition from dollar-backed stablecoins.
Pix, however, may not be competing with stablecoins.
“In practice, they are complementary,” Rodrigo Caggiano, founder of Brazilian real-world asset monitoring platform RWA Monitor, told CoinDesk. “Pix has addressed domestic instant payments well, while stablecoins expand what is possible by operating on blockchain networks.”
U.S. 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.
