Brazil Requires 24-Hour Delays on Some Overseas Crypto Transfers to Curb Fraud

Brazil's central bank orders 24-hour delays on certain overseas crypto transfers from Jan 1 to curb fraud, affecting exchanges, reais and some crypto deposits.

Brazil’s central bank has introduced new fraud-prevention rules requiring some cryptocurrency exchanges to delay certain overseas transfers by 24 hours. The resolution, published Aug. 7 and flagged in a report by CoinDesk, is set to take effect on Jan. 1. The measure aims to give authorities and exchanges extra time to detect suspicious activity and block fraudulent transactions.

According to coverage of the resolution, the rules apply to deposits made in Brazilian reais and certain crypto transactions, though specifics will depend on how exchanges implement the guidance. The policy is part of a broader push by regulators in Brazil to tighten oversight of crypto activity and protect consumers as digital asset use grows across the country.

For cryptocurrency exchanges operating in Brazil, the 24-hour delay means updating compliance processes and customer notices. Exchanges will likely need to enhance transaction monitoring systems, adjust risk-scoring models, and coordinate more closely with banks and payment processors to ensure the new delay window is applied consistently. While intended to prevent fraud, the rule could also affect user experience, particularly for customers accustomed to instant cross-border transfers.

Industry reaction is expected to be mixed. Supporters of stricter controls argue that temporary holds help stop scams and money laundering, and give regulators time to investigate suspicious flows. Critics may say the delay reduces the utility of crypto for legitimate cross-border payments and could push users to alternative platforms or peer-to-peer channels.

Businesses and retail users should prepare by reviewing how their exchanges handle overseas transfers, reading updated terms of service, and allowing extra time for international settlements starting in January. Exchanges will also need clear communication strategies to explain the delay and manage customer expectations.

As Brazil tightens crypto oversight, observers will watch how other markets respond and whether similar fraud-prevention measures spread internationally. For now, the resolution—reported by CoinDesk and noted by industry outlets like PYMNTS.com—signals a regulatory focus on balancing innovation with consumer protection in Brazil’s growing crypto ecosystem.
