Brazil stablecoin market growth

June 2026 tax data revealed that stablecoins accounted for roughly 80 % of all crypto‑asset transactions reported in Brazil, with USDT alone handling about 89 % of that volume. The government responded by preparing the DeCripto platform, which will require exchanges and service providers to report stablecoin activity under the OECD’s Crypto‑Asset Reporting Framework, aiming to improve tax collection and curb illicit use.

By late July 2026, stablecoins had moved beyond a tax‑reporting focus to become a central element of Brazil’s payments infrastructure. Transactions such as an Argentine user settling a bill through Brazil’s Pix system and a Brazilian paying a foreign‑card bill via Pix were processed instantly on‑chain using stablecoins. Global market figures showed the stablecoin sector reaching roughly US$317 billion, with on‑chain transaction values exceeding US$33 trillion in the past year—outpacing traditional payment networks. Projections from Citi suggest the market could swell to US$1.9 trillion by 2030, underscoring how Brazil’s 80 % share of declared crypto volume is now viewed as a cornerstone of cross‑border payment flows and attracting heightened scrutiny from the Central Bank.
