Brazil Tightens Crypto Oversight With $10,000 Self-Custody Reporting Rule and 24-Hour Hold
Brazil is expanding oversight of cryptocurrency transfers involving self-custody wallets as regulators strengthen anti-money laundering and fraud controls. Starting October 1, transfers worth $10,000 or more to or from self-custody wallets must be reported to Brazil’s Council for Financial Activities Control, known as Coaf.
The rule does not cap crypto transfers or prohibit self-custody. Instead, it gives authorities more visibility into transactions where users control their own private keys.
Self-Custody Moves Into AML Framework
The Central Bank of Brazil introduced the reporting requirement through Resolution BCB 588. The measure applies to regulated institutions handling virtual assets and treats the $10,000 threshold as a reporting trigger rather than a transaction limit.
Self-custody wallets can operate without a traditional custodian maintaining transaction records. Brazilian regulators have therefore argued that these transfers can provide less information for monitoring and risk assessment.
CoinDesk reported that the new rule requires covered institutions to report qualifying transfers involving self-custody wallets to Coaf. The requirement forms part of Brazil’s broader effort to bring crypto activity further into its anti-money laundering and counter-terrorist financing framework.
A Separate 24-Hour Transfer Delay
Brazil is also introducing a separate precautionary measure that could slow certain crypto transfers.
Under Resolution BCB 584, transfers above $10,000 destined for self-custody wallets or foreign virtual-asset providers can face a temporary hold of up to 24 hours. The threshold can apply to a single transaction or the customer’s total activity during the same day.
The measure will take effect January 1, 2027. Providers can release a transfer earlier after completing a documented risk assessment. The central bank has described the hold as a precautionary measure rather than a permanent freeze.
The rules also c over stablecoins and allow providers to apply additional scrutiny to smaller transactions when their risk controls identify potential fraud concerns.
Brazil’s expanding framework shows how regulators are trying to balance cryptocurrency access with greater visibility into transactions that can move rapidly beyond traditional financial intermediaries.
