Brazil's Biggest Bank Makes Its Crypto Move: Itaú Formalizes Bitcoin Trading and Custody Under New Rules
Brazil's largest private-sector bank is bringing its existing cryptocurrency business into the country's updated regulatory framework. Itaú Unibanco notified the Central Bank of Brazil on October 27 that it intends to operate cryptocurrency trading and custody services under the new rules, according to reports published on October 28.
The move comes just days before an October 30 compliance deadline for certain businesses already operating in Brazil's digital-asset market. It also places a major traditional financial institution at the center of a regulatory transition that could reshape how banks and cryptocurrency companies provide services to customers.
Importantly, this is not the launch of an entirely new cryptocurrency product. Itaú has offered crypto trading through its Íon investment platform since December 2023. The latest development concerns the formal notification of those activities under Brazil's new regulatory framework.
What Has Itaú Unibanco Announced?
Itaú Unibanco has notified the Brazilian central bank about its cryptocurrency intermediation and custody activities, according to reporting by CoinDesk and other financial news outlets.
The distinction between trading and custody is important. Trading services allow eligible customers to buy or sell digital assets, while custody involves safeguarding those assets on their behalf.
Itaú's existing service initially gave customers access to Bitcoin (BTC) and Ether (ETH) through its investment platform. The bank has subsequently expanded its cryptocurrency offering. Recent reports indicate that its platform supports 15 digital assets, although the available selection may depend on the product and customer eligibility.
For customers, using a bank-based platform can provide a familiar route into cryptocurrency investing. However, access through a traditional bank does not eliminate the market risks associated with digital assets, including price volatility, operational risks and the possibility of losses.
The regulatory notification is therefore significant primarily because of how it positions the bank's existing activities within Brazil's evolving financial rules, rather than because it introduces cryptocurrency trading to Itaú customers for the first time.
Why the October 30 Deadline Matters
Brazil has introduced a more structured regulatory framework for virtual-asset businesses, with rules covering activities such as cryptocurrency intermediation and custody.
Resolution BCB 520, which took effect on February 2, 2026, established requirements for virtual-asset service providers and specified how eligible financial institutions can conduct these activities.
The framework distinguishes between financial institutions already authorized by the central bank and dedicated cryptocurrency businesses.
Banks that already operate under the regulator's supervision can follow a notification route for eligible virtual-asset activities, subject to the applicable requirements. Dedicated cryptocurrency service providers, by contrast, must follow the relevant authorization process.
For businesses covered by the transition arrangements, October 30 is an important compliance date. The procedures and obligations are not identical for every type of institution, so the deadline should not be interpreted as a single licensing rule applying equally to all banks and crypto exchanges.
Itaú's notification ahead of the deadline illustrates how an established bank is addressing the new framework while maintaining its existing digital-asset business.

Itaú Has Been Offering Crypto Trading Since 2023
Although the latest regulatory development is new, Itaú's involvement in cryptocurrency trading dates back nearly three years.
On December 4, 2023, the bank announced that customers would be able to buy and sell Bitcoin and Ether through Íon, its investment platform. The initial service included custody provided by Itaú itself and allowed eligible customers to start with an investment of R$10.
The bank later expanded access to the service. In June 2024, Itaú announced that cryptocurrency trading would be available to all active customers using the Íon investment platform, subject to the platform's conditions.
The product was developed as part of Itaú Digital Assets, the bank's digital-asset business unit. Its strategy has included exploring how customers can access crypto investments through established financial services.
This history matters because it shows that the October 2026 development is a regulatory milestone for an existing operation, not the bank's first entry into the cryptocurrency market.

What Does This Mean for Brazil's Crypto Industry?
Brazil has developed an active digital-asset market, with demand coming from retail investors, financial institutions and businesses exploring blockchain-based services.
The country's updated rules aim to establish clearer requirements for firms involved in virtual-asset activities. A defined regulatory framework can help clarify which institutions may provide services, what standards they must meet and how their operations are supervised.
For banks, this creates a path to participate in cryptocurrency markets within their existing regulatory structures. For specialist crypto businesses, the authorization process can bring additional compliance obligations.
The transition may also influence competition. Banks already have customer relationships, established financial infrastructure and experience operating within regulated markets. Cryptocurrency exchanges, meanwhile, may offer specialized products and a broader range of trading features.
Neither model automatically guarantees a better customer experience. The outcome will depend on pricing, asset selection, security controls, service quality and the requirements imposed by regulators.
Itaú's notification is therefore worth watching as an example of how a major bank is adapting its digital-asset operations to a more formal regulatory environment.
Will Itaú Customers Get New Cryptocurrency Features?
The notification does not, by itself, confirm a new token listing, a new trading application or an immediate expansion of the bank's services.
Itaú already offers cryptocurrency trading through Íon. Any future changes to the number of supported assets, fees, custody arrangements or customer eligibility would need to be confirmed separately.
The bank has also not publicly disclosed the total number of customers using its crypto service or the total trading volume processed through the platform in the reports reviewed for this article.
Those figures would help investors assess the scale of its cryptocurrency business, but the regulatory notification alone does not establish how much demand the service is attracting.
Customers considering crypto investments should check the bank's current product terms, available assets, fees and custody conditions before making decisions. They should also understand the difference between holding cryptocurrency and investing in a conventional financial product that tracks its price.
How Is Crypto Custody Different From Trading?
Cryptocurrency trading and custody are closely related, but they serve different functions.
Trading refers to buying and selling digital assets. Custody concerns how those assets are stored and controlled.
With a custodial arrangement, a service provider safeguards the crypto assets for the customer. This can make access more familiar for people accustomed to conventional investment platforms, but it also means customers should understand the provider's security arrangements, account terms and procedures for accessing or transferring assets.
In self-custody, individuals control the private keys associated with their wallets. This offers greater direct control but also places more responsibility on the user to protect those keys and maintain access.
Itaú's existing crypto service includes custody by the bank. Its latest regulatory notification covers its crypto trading and custody activities under the updated framework.
The broader significance is that cryptocurrency services are becoming part of a more clearly defined regulatory conversation within Brazil's established banking sector.
What Happens Next?
The immediate question is how other Brazilian financial institutions and cryptocurrency businesses respond to the regulatory transition.
Itaú's notification could provide a useful reference point for understanding how an established bank brings existing crypto operations within the new rules. Other institutions may take different approaches depending on their business models, current authorizations and readiness to meet the relevant requirements.
The regulatory framework may also influence how digital-asset services are structured in the future. As rules become clearer, banks and specialist providers will need to balance customer demand with operational resilience, compliance and appropriate risk controls.
For customers, the most important issue is not simply whether a major bank offers cryptocurrency services. It is whether those services provide clear terms, appropriate safeguards and transparent information about the risks involved.
The Bottom Line
Itaú Unibanco's notification to Brazil's central bank marks an important regulatory step for one of the country's largest financial institutions. The bank has offered cryptocurrency trading and custody since 2023, and the latest move brings those existing activities into focus as Brazil implements its updated digital-asset framework.
The development highlights the growing connection between traditional banking and cryptocurrency markets. However, it should not be mistaken for a brand-new product launch or a guarantee that crypto investments have become risk-free.
As Brazil's regulatory transition continues, Itaú's approach will be worth watching alongside the responses of other banks and specialist crypto providers.
