BCB 519, 520 and 521: the October 30, 2026 deadline

Brazil's Central Bank rules for virtual asset providers give until 10/30/2026 to apply for authorization. What changes and why it matters.

On November 10, 2025, the Central Bank of Brazil (BCB) published BCB Resolutions 519, 520 and 521, which bring the virtual asset market inside the rules of the financial system. They took effect on February 2, 2026, and companies already providing these services on that date have until October 30, 2026 to apply to the Central Bank for authorization.

What happened

After Brazil's legal framework for crypto assets, Law 14,478 of 2022, the Central Bank became the regulator of virtual asset service providers. The three November 2025 resolutions are the regulations for that task.

Together, they create virtual asset service provider companies, SPSAVs (sociedades prestadoras de serviços de ativos virtuais), in three categories: intermediary, custodian and broker. They extend to these companies the rules that already applied to financial institutions, such as consumer protection, transparency, prevention of money laundering and terrorist financing, governance, cybersecurity and internal controls. And they require client assets to be segregated.

Resolution 521 brings part of these activities into the foreign exchange market. International payments and transfers with virtual assets and operations with assets referenced to fiat currency, the so-called stablecoins, are now treated as foreign exchange operations, with reporting obligations to the Central Bank that began on May 4, 2026.

The adaptation period is 270 days from February 2, 2026, which leads to October 30, 2026. Those who were already operating may continue while their application is under review, without expanding their activities. According to Migalhas, those who do not apply for authorization by the deadline will have to cease operations, and authorized institutions will no longer be able to deal with unauthorized counterparties.

Why it matters

For many years, the crypto asset market in Brazil grew in a gray zone. Any company could offer buying, selling and safekeeping of digital assets without asking anyone for a license. The new rules end that period. From now on, whoever holds another person's assets answers to the regulator the way a bank or a brokerage does.

For users, this means more protection: assets separated from the company's own, transparency rules and a clear place to complain. For the sector, it means cost and selection. Capital, governance and control requirements will separate those who have structure from those who have only an app.

There is also an effect on foreign trade. By treating part of stablecoin operations as foreign exchange, the Central Bank recognizes that they already function as a means of payment between countries, and decides that this use must follow the same rules as any remittance.

A related fact reinforces this reading. On August 7, 2026, the Central Bank published BCB Resolution 584, which creates a 24-hour precautionary hold on transfers above US$ 10,000 destined for foreign crypto asset companies or self-custody wallets. The rule applies from January 1, 2027.

In Bairo's view

Bairo Leandro Gonzalez Martinez has long written that innovating outside the rules is just another way of leaving the small player exposed. In his reading, the 2025 resolutions do not slow innovation: they create the ground on which it can grow without deceiving anyone.

For Bairo, the infrastructure that connects agribusiness to the world needs three things at once: speed, verifiable records and clear rules. The grower who one day gets paid for an exported shipment needs to know who holds their money and whom to turn to. In his view, this is not bureaucracy. It is respect for the lifetime of those who worked to produce that shipment.

He also makes a point of keeping things separate. A public record network, which anyone can check, is one thing. A service that holds and exchanges assets for clients is another, and that one requires authorization. For Bairo, knowing which side of the line each activity falls on is the first task of anyone building in the sector.

Where this meets the ecosystem

The fronts Bairo founded treat this deadline as a fact on the calendar. The BTZ Chain is a public network, which anyone can check in the explorer, and BICOIN is this network's governance coin, with the yardstick "1 BTZ = 1 minute of human life", which measures purpose and is not a price, an offer or an invitation to buy. How any service linked to it fits under the Central Bank resolutions depends on a legal opinion, and no compliance is claimed before that.

CEASA Bank is an agribusiness financial platform that operates on the infrastructure of an authorized institution. Custody of digital currencies is part of its design, always with authorized institutions in each country, and the Brazilian rule defines the path for that.
