Brazil's Central Bank is implementing new regulations aimed at reducing financial fraud by requiring cryptocurrency exchanges to delay certain transactions. Starting January 1, 2027, transfers exceeding $10,000 to international platforms and self-custody wallets will face a hold of up to 24 hours.
This rule, detailed in Resolution BCB No. 584/2026, published on August 7, also allows smaller transactions to be delayed if flagged as potentially suspicious by the exchanges. The central bank has raised alarms over the use of cryptocurrencies, including stablecoins, in facilitating fraudulent fund transfers before victims or institutions can act.
While the 24-hour hold is standard, exchanges can expedite a transaction if their risk assessments show no signs of illegality, provided they document their decision and notify customers of any holds. The new regulation increases the responsibility of exchanges to assess risks based on various factors, including customer profiles and transaction specifics.
