Three of Brazil's largest financial institutions are now operating as crypto brokerages for millions of retail customers. Itaú, Nubank, and Banco do Brasil have each built token menus that rival some standalone exchanges — all while maintaining a strict policy of never holding a single satoshi on their own books.

The expansion coincides with the Brazilian Central Bank's new regulatory framework for virtual asset service providers, which took effect in February 2026. The framework has introduced institutional guardrails that give compliance departments far greater certainty.

The move comes in one of the world's most active crypto markets. Brazil has repeatedly ranked among the largest crypto economies globally, with the BCB reporting millions of individuals declaring digital-asset holdings on annual tax filings in recent years. Until now, much of that demand flowed through foreign and domestic standalone exchanges; the banks' entry puts regulated incumbents in direct competition with those platforms for the same retail base.

What the banks are actually doing

Itaú, the country's largest private bank, began 2025 by offering 15 different tokens to retail clients, including Bitcoin and ether. Banco do Brasil, the state-controlled giant, followed suit by launching direct investment access to Bitcoin and ether in January 2026. Both institutions treat crypto as simply another asset class available through their existing brokerage platforms.

Nubank has been the most aggressive of the three. The digital bank expanded its crypto platform to 28 assets, adding four new tokens in May 2026 alone. More than 7 million users now trade crypto through its app — a scale that illustrates how mainstream digital-asset trading has become within Brazilian retail finance.

The critical detail is how these banks have structured their exposure. None of them hold crypto on their balance sheets. They act purely as custodians and intermediaries, connecting clients to digital assets without taking on volatility risk themselves. Each bank classifies its crypto services as high-risk investments, complete with mandatory risk disclosures that clients must receive before they can trade.

The regulatory framework behind the push

The Brazilian Central Bank (BCB) passed resolutions at the end of 2025 establishing a formal regulatory framework for virtual asset service providers. Those rules went live in February 2026.

The framework covers authorization requirements, capital adequacy standards, mandatory asset segregation, and proof of reserves. In practical terms, companies that want to offer crypto services in Brazil must now prove they have enough capital to operate, keep client funds separate from their own, and demonstrate that they actually hold the assets they claim to hold.

For banks already accustomed to heavy regulation in traditional finance, these requirements are familiar territory. That is precisely why the framework has made it easier for incumbents like Itaú and Banco do Brasil to enter the space: they already possess the necessary compliance infrastructure. The same rules, conversely, raise the bar for smaller unregulated players, and the framework sits alongside a separate BCB initiative to develop a digital real (Drex), the central bank's tokenized currency pilot — a signal that Brazilian authorities are building a comprehensive rulebook for digital assets rather than reacting to them piecemeal.
