Stablecoin rules across Latin America in 2026

Brazil reclassified operations involving fiat-pegged stablecoins as foreign-exchange transactions effective Feb. 2, 2026, under Central Bank resolutions published Nov. 10, 2025. The rules establish mandatory licensing for virtual asset service providers, require reporting from May 2026 and set a licensing transition deadline of Oct. 30, 2026.

The Brazilian framework brings covered cross-border stablecoin payments into the 3.5% IOF-Câmbio tax from February 2026. A separate rule prohibits electronic foreign-exchange providers from using stablecoins for cross-border settlement from Oct. 1, 2026. Licensed firms must segregate client assets and present independent proof-of-reserves certification. After Oct. 30, 2026, licensed institutions will be barred from transacting with unauthorized counterparties.

Mexico’s 2018 Fintech Law allows the public to use cryptocurrencies but prevents regulated financial institutions from offering virtual-asset services directly to customers. In May 2026 lawmakers introduced the Murat Initiative, a proposal to create a formal peso-referenced stablecoin regime spanning ten financial laws. Mexico received $61.8 billion in remittances in 2025.

Argentina requires virtual asset service providers to register with the national securities regulator under the PSAV registry established by Resolution 994/2024 and operationalized by Resolution 1058/2025. Anti-money-laundering obligations apply under Law 27,739. Registration covers foreign providers that target Argentine residents. Stablecoins accounted for more than 60% of crypto activity in Argentina and monthly active user penetration reached 12% in 2025.

Colombia has not introduced a dedicated VASP licensing regime. Stablecoin activity there is subject to general anti-money-laundering rules. The Bre-B instant-payment system, launched in October 2025, connected 218 financial institutions and about 33 million users within six months. Stablecoins made up roughly 48% of exchange purchases in 2024. Limits on USD bank accounts and a roughly 15% peso depreciation, from about COP 3,822 to COP 4,409 per dollar over a year, contributed to demand for dollar-denominated value on-chain.

Bolivia lifted an outright ban on cryptocurrencies in 2024 and recorded $14.8 billion in crypto transaction volume in the following 12 months. By April 2026 state-controlled Banco Unión was selling USDT through its Yasta wallet and Banco FIE added USDT buy-and-sell functions in its mobile app. The Economy Ministry is reviewing a framework that would recognise USDT as a payment instrument circulating alongside the boliviano and the dollar. Transaction-level evidence shows parallel-market dollar premiums reached about 80–95% above the official rate during the shortage.

At a regional level, Latin America processed about $324 billion in stablecoin transactions in 2025, up 89% year-on-year. More than half of exchange purchases were stablecoins in Brazil, Argentina and Colombia. In Brazil, over 90% of crypto transaction volume is stablecoin-related.

Market operators report common operational requirements across countries: licensing in each jurisdiction, cross-border compliance frameworks, access to local liquidity and integration with local payment rails. Reserve and audit standards are part of authorization requirements in markets such as Brazil. International rules enacted in 2025 and 2026 are being used as reference points for reserve standards and restrictions on certain yield products.

Regulators in the region have published deadlines, reporting obligations and tax treatments that affect settlement costs and operational models. Market participants face licensing timetables, proof-of-reserves demands and, in some cases, new taxes while operators and banks adjust to varied national rules.
