Brazil will require regulated financial institutions to report crypto transfers worth at least $10,000 involving self-custody wallets from 1 October.
Under Resolution BCB 588, institutions authorised by the Banco Central do Brasil must notify the Financial Activities Control Council (Coaf) when they send virtual assets of that value to a self-custody wallet or receive the same amount from one.
The rule applies to both deposits from and withdrawals to wallets controlled directly by users. Responsibility for filing rests with the institution processing the transaction, which must submit details to Coaf by the next business day under Brazil’s existing anti-money-laundering framework.
Reports will be triggered automatically once the value and transaction type meet the threshold. Institutions will not first have to decide whether a transfer appears suspicious. As a result, a legitimate movement between an exchange and a customer’s personal wallet can be reported solely because it reaches $10,000 and involves self-custody.
Financial institutions in Brazil already have separate obligations to report transactions they judge to be suspicious. The new measure adds another layer of oversight, giving authorities information about large transfers crossing between regulated platforms and privately controlled wallets, even where no suspicious activity has been identified.
The October rule comes before further restrictions on some crypto transfers leaving regulated institutions. Resolution BCB 584 is due to take effect on 1 January 2027 and establishes a precautionary holding procedure for certain outbound virtual-asset transactions.
Under that framework, transfers can be delayed while additional checks take place, although they may be released earlier when specified conditions are met.
Exchanges, banks and other covered providers will need to identify self-custody counterparties, calculate transaction values and build automatic Coaf reporting into their monitoring systems before the October deadline. From January, some will also require procedures for holding outbound transfers for further review.
Rules introduced as Brazil’s crypto market expands
The measures are being brought in as Brazil remains one of the world’s largest crypto markets.
Brazil recorded $252.5 billion in crypto activity during the period measured by Chainalysis, making it the largest market in Latin America and placing it first in the firm’s 2026 global crypto adoption index.
The overall ranking reflects broad participation rather than leadership in every category. Brazil ranked third for flows through crypto services, fourth for on-chain balances, third for domestic peer-to-peer activity and second for cross-border flows. The United States ranked second overall.
The scale of that activity means the self-custody threshold could have a significant commercial impact. High-value users, trading firms and businesses that frequently move assets between regulated platforms and private wallets are more likely to generate automatic filings, while exchanges will carry the operational burden of identifying and reporting qualifying transactions.
Brazil’s crypto economy nevertheless contracted by 1.6% during the latest period, indicating that the expansion of regulatory oversight comes as short-term activity has cooled.
