Summary
Brazil’s central bank will require crypto exchanges to delay certain transfers of crypto assets abroad and to self-custody wallets by up to 24 hours. This rule applies to transfers exceeding $10,000 or smaller amounts flagged as risky by exchanges. The new anti-fraud measure, outlined in Resolution BCB No. 584/2026, takes effect on January 1, 2027.
Why it matters
This development aims to curb the use of cryptocurrencies, including stablecoins, in financial fraud by slowing transactions that may involve illicit funds. It increases the responsibility of exchanges to assess transaction risk and intervene when necessary, potentially impacting user experience and cross-border crypto activity.
Key context
The rule targets transfers where customers deposit Brazilian reais or crypto with exchanges and then move funds abroad or to their own wallets. The central bank states that crypto is used to move fraudulently obtained funds quickly, sometimes before recovery actions are possible. Exchanges can release funds earlier than 24 hours if no wrongdoing is detected, and they must notify customers of delays and document their decisions.
