Brazil introduces a 24-hour freeze on crypto transfers: a new front in the fight against fraud
Brazil's Central Bank (BCB) is tightening the rules for the crypto industry. According to new Resolution No. 584, published on Friday, all licensed services operating with virtual assets will be required to suspend part of transfers for 24 hours. This is not just a formality — it is a direct blow to fraudulent schemes that cause billions in losses to Brazilian investors every year.
The new regulation extends existing anti-fraud mechanisms applied to traditional payment systems to companies operating with digital assets. The key innovation is a mandatory "pause" for risk assessment. This is not about permanently blocking funds, but about a temporary freeze that gives businesses time to conduct a detailed analysis of a suspicious transaction.
How the 24-hour freeze works
The rule takes effect for transfers of $10,000 or more. The threshold is calculated both for a single transaction and for the total volume of all client settlements within a day. The restriction also affects transfers to foreign crypto services and to self-custody wallets, where the user fully controls their private keys.
The regulator emphasizes the preventive nature of the measure. Funds are not blocked irrevocably: the client receives a notification about the freeze and its exact duration. After 24 hours, the company must either immediately execute the transaction or refuse it. Early "release" of funds is only possible based on a reasoned decision made in strict compliance with internal risk management rules.
The requirement applies to all Brazilian virtual asset services, including stablecoin operators — digital currencies pegged to fiat money or other assets. This closes the loophole through which fraudsters could withdraw funds through less regulated market segments.
Additional measures and implementation timeline
The resolution also requires companies to record daily cases and attempts of fraud in payment and virtual asset operations, as well as to regularly report on the measures taken. This creates a database for analyzing and improving protective mechanisms at the state level.
The new rules take effect on January 1, 2027. At the same time, the BCB reserves the right to expand its powers: extending the freeze beyond 24 hours, lowering the $10,000 threshold, and prohibiting services from prematurely lifting the block in case of violations. This is a clear signal to the market: the regulator is ready for further tightening if the initial measures prove insufficiently effective.
My view: introducing a mandatory freeze is a double-edged sword. On one hand, the measure could indeed reduce the number of successful attacks, especially on inexperienced users. On the other hand, the 24-hour delay creates friction for legitimate transactions and could push some clients toward unregulated offshore platforms. Brazil has chosen the path of strict control, and now the market will have to adapt to a new reality where transfer speed gives way to security.
