Brazil's central bank will require cryptocurrency exchanges to delay certain customer transfers to foreign platforms and self-custody wallets for up to 24 hours under new anti-fraud rules aimed at curbing the use of digital assets in financial fraud.
The requirement takes effect January 1, 2027, under Resolution BCB No. 584/2026, published August 7. The rule applies when a customer deposits the country's fiat currency, the real, or cryptocurrency with an exchange and subsequently seeks to send the funds abroad or to a wallet under their own control.
Brazil ranks among the largest cryptocurrency markets in Latin America, and the new rule represents one of the region's most specific mandates targeting the speed of crypto withdrawals and cross-border transfers rather than imposing outright restrictions.
Transfers exceeding the equivalent of $10,000—whether conducted as a single transaction or multiple transactions on the same day—are subject to the mandatory hold. Smaller transfers may also be delayed if an exchange flags them as risky.
The central bank stated that cryptocurrencies, including stablecoins, are being used to move funds obtained through financial fraud before victims or institutions can recover them. The use of stablecoins for cross-border value transfer has drawn increasing attention from regulators across emerging markets.
The hold is not permanent. Exchanges may release a transfer before the 24-hour period expires if their internal risk review finds no signs of wrongdoing. They must document that decision and notify customers when a transaction has been placed on hold.
The measure also assigns exchanges greater responsibility for assessing risk based on the customer, the transaction, the counterparty, and the destination jurisdiction.
Regina Pedroso, president of Brazilian tokenization industry group Abtoken, said the policy could impose costs on legitimate users and weaken the competitiveness of domestic exchanges, according to local news outlet Portal do Bitcoin. The 2027 implementation date gives the industry a window to develop compliance procedures before the rules take effect.
