Brazil's central bank just put a speed bump in front of crypto. Starting January 1, 2027, exchanges will be required to hold certain crypto transfers for up to 24 hours before sending them abroad or to a self-custody wallet. Resolution BCB No. 584, approved on August 6 and published the next day, kicks in once a transfer — or the sum of same-day transfers — passes $10,000.
The reasoning is straightforward. Fraudsters have figured out that moving stolen money through a stablecoin is faster and harder to trace than routing it through a bank. By the time a victim notices and calls their bank, the funds are often already gone — parked on a foreign platform or a wallet nobody can freeze. The 24-hour window gives exchanges time to check the destination, the counterparty's jurisdiction and the customer's history, and to pause anything that looks off. If a review comes back clean, the money can move before the clock runs out.
There's a certain irony here: Brazil built its reputation on Pix, the instant-payment rail that much of Latin America now looks to as a model. Crypto, long sold on the promise of speed, is about to move slower than a bank transfer in the very market that popularized real-time payments.
Not everyone is cheering. Regina Pedroso, who heads the Brazilian tokenization group Abtoken, warned the rule could burden legitimate users and put local exchanges at a disadvantage against foreign platforms it doesn't directly reach. Exchanges have roughly five months to build out the compliance machinery — the central bank is clearly betting they'll use the time to tighten screening, not just look for workarounds.
