Brazil's central bank will require virtual asset service providers (VASPs) to place precautionary holds of up to 24 hours on certain transfers to foreign platforms or self-custody wallets as part of new measures aimed at preventing fraud. The Banco Central do Brasil (BCB) announced Friday that the requirement will apply to funds received above $10,000, either in a single transaction or based on a customer's total transactions in a day. Providers must also hold other transfers requiring further scrutiny under their risk-management policies.
The rules take effect on Jan. 1, 2027, giving firms time to adapt their compliance systems. Providers must notify customers of holds and keep records of fraud incidents, attempted fraud and corrective actions. A VASP may complete its assessment and release a transfer before the 24 hours expire, provided that it follows parameters set out by the central bank.
The measure adds Brazil to a growing list of jurisdictions tightening crypto safeguards as regulators confront scams that exploit the speed and cross-border reach of digital assets. By imposing a 24-hour window, authorities aim to create a cooling-off period that can help intercept fraudulent transactions before funds are irrevocably moved to overseas accounts or wallets controlled by criminals.
Brazil's evolving crypto regulatory landscape
Brazil has been actively shaping its digital asset regulatory framework in recent years. In 2023, the country passed a legal framework for virtual asset service providers, granting the central bank authority to regulate the sector. Since then, the BCB has moved to integrate crypto businesses into the traditional financial system while addressing risks such as money laundering, tax evasion and fraud.
The latest measure targets an area of growing concern: cross-border cryptocurrency movements. Fraudsters often use overseas platforms and self-custody wallets to obscure the trail of stolen funds. By forcing VASPs to hold suspicious transfers for up to 24 hours, regulators gain a critical window for investigation. The rules apply not only to single transactions above $10,000 but also to cumulative daily transfers that exceed that threshold, preventing criminals from splitting large sums into smaller, less noticeable payments.
According to the BCB, the decision followed consultations with market participants and public feedback. The central bank emphasized that the precautionary hold does not amount to a freeze or seizure of assets; rather, it is a temporary measure to allow providers to complete due diligence. Customers will be informed immediately when a hold is placed, and the reasoning behind the review must be clearly communicated.
How the 24-hour hold works
Under the new rules, a VASP receiving funds above the $10,000 threshold must notify the customer of the hold and begin an internal assessment. The assessment may include verifying the origin of funds, checking the beneficiary against sanction lists, reviewing transaction patterns, and confirming the customer's identity. If the provider concludes that the transfer is legitimate, it may release the funds before the 24-hour period ends. However, the central bank will define specific parameters for early release to ensure consistency and prevent arbitrary decisions.
For transfers that fall below the $10,000 threshold but still raise red flags under a provider's risk-management policy, the same type of hold can be applied. This broadens the scope of the rule beyond a simple monetary limit, allowing VASPs to exercise judgment based on customer behavior, jurisdictional risks or other indicators of potential fraud.
The central bank also requires VASPs to maintain detailed records of all fraud incidents, attempted fraud and corrective actions taken. These records must be made available to regulators upon request. This data will help the BCB assess the effectiveness of the new rules and identify emerging threats in the crypto ecosystem.
Brazil joins global push against crypto scams
Brazil's move follows anti-scam measures introduced in other jurisdictions. In Japan, the Financial Services Agency and National Police Agency asked crypto exchanges to restrict withdrawals after customers deposit fiat currency or buy digital assets. Japanese authorities also called for platforms to require customers to preregister withdrawal addresses and impose a waiting period before newly added addresses can be used.
Other proposed safeguards in Japan include customer-specific withdrawal limits, stronger monitoring, phishing-resistant multifactor authentication and checks that the name of a bank remitter matches the crypto account holder. Unlike Brazil's regulation, the Japanese measures are not binding. In addition, exchanges can determine implementation based on their operations and exposure to misuse.
European regulators have also stepped up warnings. The European Securities and Markets Authority (ESMA) and the European Banking Authority have highlighted the rise of crypto scams that use fake websites, impersonation of official bodies and social media manipulation. In France, the financial regulator reported cases involving fake websites that mimicked licensed platforms. ESMA said scammers had misused its identity and logo in falsified documents, urging investors to verify all official channels.
The EU's Markets in Crypto-Assets (MiCA) regulation, which created a comprehensive licensing regime for crypto firms in the bloc, has become a target for fraudsters. Criminals have been known to contact investors, pretending to be authorized firms or regulators, and direct them to fraudulent websites. These scams often prey on users searching for legitimate platforms that have obtained a MiCA license.
Context: Crypto fraud in Latin America
Brazil's new measure comes amid a broader crackdown on crypto-related crime across Latin America. The region has seen a surge in digital asset adoption, driven by economic instability, currency devaluation and a young, tech-savvy population. At the same time, fraudsters have exploited the decentralized nature of cryptocurrencies to orchestrate Ponzi schemes, ransomware attacks and phishing campaigns.
In Brazil specifically, law enforcement has dealt with several high-profile crypto fraud cases. In recent years, authorities dismantled operations that promised extraordinary returns on crypto investments but siphoned funds from thousands of victims. The new transfer hold is seen as a preventive tool to stop fraudulent funds from leaving the country before victims even realize they have been scammed.
Crypto exchanges and wallet providers operating in Brazil will need to update their internal procedures to comply with the new rules. This includes implementing real-time transaction monitoring, integrating customer notification systems and training staff to handle fraud assessments. Smaller VASPs may face a heavier burden, as they may lack the sophisticated compliance infrastructure of larger platforms.
Implications for consumers and businesses
For ordinary crypto users, the 24-hour hold introduces a potential delay in accessing funds, particularly for high-value transfers. However, the central bank has stressed that legitimate transactions will generally be released without delay if the provider can quickly verify their validity. Customers should be prepared to provide additional documentation if needed, such as proof of origin of funds or a clear explanation of the purpose of the transfer.
Businesses that rely on crypto cross-border payments may need to factor in the possibility of holds when managing cash flow. The rule could affect remittances, purchase transactions and settlement between trading partners. While the $10,000 threshold is high enough to exempt most retail users, institutional investors and high-net-worth individuals are more likely to encounter the measure.
VASPs will also need to align their policies with the BCB's parameters for early release. According to the central bank, the goal is not to create unnecessary barriers but to enhance the integrity of the financial system. The 24-hour period is a maximum, not a minimum, and a provider that completes a satisfactory review can authorize the transfer sooner.
Global trends: Cooling-off periods and withdrawal limits
Brazil's approach mirrors a broader international shift toward what some call “cooling-off periods” in crypto transactions. The concept, long used in traditional finance to protect consumers from high-pressure sales tactics, is now being adapted to digital assets. Regulators in several jurisdictions have proposed or implemented similar measures, including in the United Kingdom, Australia and parts of Asia.
In the UK, the Financial Conduct Authority (FCA) has introduced rules requiring crypto firms to provide clear risk warnings and, in some cases, impose temporary bans on certain promotions. In Australia, the securities regulator has been exploring the use of “designated service provider” licensing with conditions that could include transfer limits and enhanced customer verification.
Asia has been particularly active. In Japan, the non-binding requests to exchanges are part of a broader effort to curb crypto-related money laundering and fraud. In South Korea, regulators have enforced real-name trading and have limited exchanges' ability to accept deposits from unverified customers. The Philippines and Thailand have also introduced stricter rules on cross-border crypto movements.
The core challenge for regulators is balancing consumer protection with innovation and financial inclusion. While too much friction could drive users to unregulated platforms, too little could allow fraud to flourish. Brazil's 24-hour hold is an attempt to find a middle ground, focusing on the highest-risk transactions and giving providers the flexibility to apply additional scrutiny when needed.
Technical and operational considerations for VASPs
Implementation of the new rule will require technological upgrades at many VASPs. Providers must be able to detect in real time whether a transaction or a daily aggregate exceeds the threshold. They must also integrate holding mechanisms that prevent the beneficiary from accessing funds until the assessment is complete. This may involve the use of smart contracts or custodial wallets that enforce time locks.
Another technical issue is travel rule compliance, which requires VASPs to share information about the originator and beneficiary of transfers. Brazil's rules align with the Financial Action Task Force (FATF) recommendations, which call for virtual asset providers to collect and share customer data for transactions above a certain threshold. The new hold system will likely complement existing travel rule mechanisms, giving institutions more time to match and verify data.
Cybersecurity is also a concern. If a VASP suffers a data breach or a fraudster gains access to its systems, the hold could be circumvented. The central bank expects providers to maintain robust security measures, including encryption, multi-factor authentication and continuous monitoring. Providers will also need to establish clear audit trails to demonstrate compliance with the central bank's parameters.
Reactions from the crypto industry
The announcement has elicited mixed reactions from Brazil's crypto sector. Some industry executives welcomed the measure as a step toward legitimacy, arguing that it will help remove bad actors and build trust among institutional investors. Others, however, expressed concern about the operational burden and the potential for delays to push users toward informal channels or foreign exchanges that are not subject to the rules.
One concern raised by VASPs is the need for clarity on the “risk-management policies” that trigger a hold for transactions below $10,000. The BCB has indicated that it will issue supplementary guidance, but firms are eager for specifics. Without clear definitions, providers may be uncertain about their legal liability and may either over-comply, holding too many transactions, or under-comply, missing fraudulent transfers.
Consumer advocates have generally supported the measure, noting that it protects victims of scams. A 24-hour delay can be crucial in freezing funds before they are laundered through multiple wallets or converted to cash. Some advocates have even proposed extending the hold period for suspicious transactions, though the central bank has not signaled any intention to do so.
What this means for Brazil's financial system
The new rule reinforces Brazil's position as a regional leader in crypto regulation. By integrating VASPs into the formal financial system and imposing sensible safeguards, the central bank aims to attract responsible innovation while minimizing risks. The 24-hour hold may also deter Brazilian residents from using unauthorized foreign platforms, as funds sent to those platforms will face additional scrutiny.
However, the effectiveness of the rule will depend on enforcement. Brazil has a history of robust financial regulation, and the central bank has shown a willingness to act against non-compliant firms. The requirement to maintain records and report incidents provides a basis for regulatory oversight, and the BCB may conduct periodic inspections to ensure VASPs are following the rules.
For now, VASPs in Brazil have until Jan. 1, 2027, to prepare. That timeline gives them ample opportunity to update their compliance systems, train staff and test the new processes. It also gives the central bank time to refine its parameters and communicate expectations clearly.
As the crypto market continues to grow, regulators around the world will be watching Brazil's experiment with transfer holds. If successful, similar measures could be adopted elsewhere, creating a new global standard for fighting crypto fraud.
For consumers, the message is clear: while Brazil's new rules introduce an extra layer of scrutiny, they are designed to protect users from the growing threat of digital asset fraud. By working with licensed providers and maintaining open lines of communication, users can ensure that legitimate transfers proceed smoothly and that attempts to steal their funds are stopped in their tracks.
