Brazil's central bank announced new anti-fraud rules that will delay some cryptocurrency transfers for up to 24 hours starting next year. According to ChainCatcher, the rule applies to transfers above $10,000 sent to foreign virtual asset companies or self-custody wallets, with the threshold calculated either per transaction or by a customer's total daily transfers.

The central bank said the measure reflects the increasing use of virtual assets, including stablecoins, to quickly move funds obtained through financial fraud. It added that the policy is not an asset freeze, will not permanently block transfers, and may also apply to other transactions that require stricter review.
