Brazil introduces 24-hour freeze on crypto transfers: a new blow to fraud
Brazil's Central Bank (BCB) is tightening the rules for the crypto industry. Under new regulation No. 584, all licensed services dealing with virtual assets are required to freeze part of transfers for 24 hours. This measure aims to combat the growing number of fraudulent schemes and gives companies time to assess risks.
How the 24-Hour Freeze Works
The new rule applies to transfers of $10,000 or more. The threshold is considered both for a single transaction and for the cumulative total of all client settlements within a day. The restriction covers not only transfers to third-party virtual asset services but also to self-custody wallets, where the private keys are controlled solely by the user.
The regulator emphasizes that the measure is preventive in nature. Funds are not blocked permanently—the client receives a notification about the freeze and its exact duration. After 24 hours, the company must either execute the transfer or refuse the transaction. Funds can be "released" early only by a reasoned decision made under risk management rules.
Additional Anti-Fraud Measures
The regulation also requires services to record daily instances and attempts of fraud in payment and virtual asset operations, as well as to regularly describe the measures taken. This creates a transparent reporting system that will allow the regulator to track the effectiveness of combating abuse.
The new rules will take effect on January 1, 2027. However, the BCB retains leverage for tightening: the regulator can extend the freeze beyond 24 hours, apply it to transfers under $10,000, and even prohibit services from lifting the block early if they violate requirements.
This step is part of a global trend toward stronger control over the crypto market. Brazil, being one of the largest markets in Latin America, is clearly seeking to create a precedent that could be adopted by other countries in the region.
My analysis: The introduction of a mandatory freeze is a double-edged sword. On one hand, it will indeed make life harder for fraudsters who use instant transfers to withdraw funds. On the other, it creates an additional burden on legitimate services and may deter some users accustomed to instant transactions. The key point will be how the BCB balances security and convenience, as well as how effectively companies can automate the risk assessment process within 24 hours.
