Expanded Central Bank crypto supervisory data and anti-fraud retention rules take effect

Starting January 1, 2027, the Central Bank of Brazil will enforce expanded supervisory reporting requirements for crypto-asset service providers, alongside a new 24-hour anti-fraud retention period for certain large transfers. The rules apply broadly to crypto-asset activity rather than to a single coin or token.

What is happening

From January 1, 2027, Central Bank-regulated virtual-asset service providers in Brazil will be required to report expanded supervisory data to regulators, covering customer balances, custody positions, proof of reserves, and assets committed to staking. This measure builds on Brazil's broader regulatory framework for virtual-asset service providers, which has already brought such companies inside the Central Bank's formal oversight perimeter through earlier resolutions.

Alongside the expanded data requirements, a separate anti-fraud measure takes effect on the same date, mandating a 24-hour precautionary retention period for virtual-asset transfers above $10,000 that are sent to overseas entities or self-custody wallets. During this window, providers must conduct additional risk checks before completing the transfer. This follows earlier rules, such as Resolution 588, which already required reporting to Coaf for virtual-asset movements of at least $10,000 involving self-custody wallets.

These 2027 requirements form part of a sequence of regulatory deadlines that Brazil's Central Bank has introduced in recent years, including licensing requirements under Resolution 519, operating rules under Resolution 520, and restrictions on dealing with unauthorized foreign virtual-asset providers effective from November 2025 under Resolution 589.

Why it matters

For crypto businesses operating in Brazil, the expanded data obligations and retention rules add to an already growing compliance burden. Reporting on custody, reserves and staking positions increases transparency for regulators but may raise operational costs for service providers, particularly smaller firms. Industry estimates cited in reporting suggest only a limited portion of crypto companies operating in Brazil were expected to pursue the authorization needed to continue operating under this framework.

For holders and traders, the retention period for transfers to overseas entities or self-custody wallets above $10,000 could introduce delays for larger transactions, though it does not prohibit self-custody or cap transaction sizes. Given that Brazil has been ranked as a leading country for grassroots crypto adoption, with stablecoins making up a large share of reported transaction volume, these rules could have a meaningful effect on how exchanges and users manage cross-border and self-custody transfers going forward.
