BCB Resolutions 519, 520 and 521: The New Virtual Assets Framework

BCB Resolutions 519, 520 and 521: The New Regulatory Framework for Virtual Assets in Brazil.

In November 2025, Brazil's Central Bank took a decisive step in regulating the crypto asset market by publishing Resolutions 519, 520, and 521. With an effective date of February 2, 2026, these rules establish the first comprehensive framework for virtual asset service providers in the country, significantly raising the institutional standards required to operate in this market.

This regulatory package not only operationalizes Law 14,478 of 2022, known as the Cryptocurrency Legal Framework, but also positions Brazil among jurisdictions with the most comprehensive sector regulation. The approach chosen by the Central Bank reflects a global trend of integrating virtual assets into the traditional financial system, in contrast to earlier models based on exceptions or regulatory tolerance.

Resolution 519 structures the authorization process for Virtual Asset Service Provider Companies, or VASPs. The model establishes three distinct categories. The first, called Intermediary, covers trading and offering activities, including buying, selling, and exchanging virtual assets, subscription of issuances, and wallet administration. The second category, Custodian, focuses on safeguarding and controlling private keys and asset access instruments. The third, Broker, is the only one that can accumulate both intermediation and custody activities simultaneously.

A critical point of the new regulation is the express prohibition on issuing stablecoins with algorithmically controlled reserves. This ban aligns Brazil with international concerns evidenced after the collapse of projects like Terra/Luna, signaling that only stablecoins with verifiable backing in real assets will be tolerated in the Brazilian market.

Resolution 520 details governance, risk management, and internal control requirements. VASPs must maintain a statutory board with at least three directors responsible for specific areas: anti-money laundering and counter-terrorism financing, internal controls, and risk and capital. The requirement for exclusive-use physical administrative headquarters, prohibiting coworking or virtual offices, reinforces the intention to raise the sector's institutional standards.

Mandatory asset segregation between client wallets and company wallets, with mandatory annual auditing, represents one of the most significant changes. This requirement aims to protect client resources in case of provider insolvency.

Resolution 521 brings perhaps the most structural change: the classification of stablecoin operations as foreign exchange operations. International payments or transfers involving virtual assets, stablecoin negotiations between residents and non-residents, and transfers to self-custodied wallets now formally integrate Brazil's foreign exchange market.

This classification has profound implications. It establishes operational limits of 100 thousand dollars per operation, or 500 thousand dollars when the counterparty is authorized. It requires correct classification of remittance purposes and information reporting to the Central Bank.

Minimum capital requirements follow a cumulative logic based on operational complexity. The base cost starts at 1 million reais for basic services, 3 million for custody, and 5 million for international operations.

The scenario projected for 2026 is one of practical consolidation of this framework. Service providers will have to adapt to new prudential, informational, and governance standards. The Brazilian crypto asset market, particularly the stablecoin and cross-border payments segment, will gain legal and institutional predictability.

The February 2, 2026 deadline is not just a compliance date. It is the milestone of a new era for virtual assets in Brazil.
