Understand, therefore, how the misuse of bank accounts turns ordinary citizens into investigated individuals and what the legal risks involved are
A simple request can trigger serious consequences.
A friend asks for your account to receive a PIX. You accept without questioning.
Days later, however, authorities may initiate an investigation. The transferred amount may have a criminal origin. Thus, your CPF (Brazilian individual taxpayer ID) appears in the inquiry.

Germany took 1,468 days to drill 9,101 meters of the Earth’s crust, faced temperatures of 265 degrees, crossed faults saturated by fluids under pressure, and revealed that the continental crust remains active, stressed, and permeable far beyond the limits that science considered possible.
This scenario, as observed in 2026 in Brazil, has become frequent. People with no criminal intent end up involved in money laundering cases.
What defines a straw account in the financial system
Firstly, a straw account is one used to move illicit funds. Even if the holder is unaware of the origin, accountability can still occur.
Furthermore, in Brazilian law, deliberate ignorance can be equated to intent. In other words, accepting a suspicious situation without questioning can lead to penalties.
In this context, three profiles frequently appear:
- Friend or family member: lends the account out of trust, without verifying the origin of the funds
- Conscious participant: provides the account for payment, knowing about the irregularity
- Victim of fraud: has data used without authorization, but needs to prove innocence

Money laundering law provides for severe penalties
According to Law nº 9.613/1998, updated in 2012, the penalty can reach 10 years in prison, in addition to a fine.
Furthermore, anyone who receives, transfers, or allows the use of the account can be charged.
The consequences, on the other hand, go beyond the criminal sphere:
- Loss of assets linked to the crime
- Restriction for public office and financial activities
- Negative records at the Central Bank
- Difficulty accessing credit and banking services
PIX boosts growth of financial fraud
Since the launch of PIX by the Central Bank in 2020, the system has facilitated instant transactions.
However, at the same time, criminals began to move funds quickly, making tracking difficult.
The data highlights the progression of the problem:
- In 2022, fraud generated R$ 2.5 billion in losses, according to the Central Bank
- In 2023, more than 1.6 million Brazilians were identified as straw persons, according to Serasa Experian
- In 2024, PIX moved R$ 26 trillion, according to the Central Bank
- In 2025, the number reached 2.6 million profiles, a 62% increase, according to Serasa Experian
Furthermore, according to Serasa Experian, about 70% of cases involve conscious participation.
Therefore, many occurrences begin with quick decisions and without risk analysis.
How to avoid involvement in illegal schemes
First and foremost, it is crucial to question any request to use your account.
After all, anyone who needs to receive a PIX can use their own account.
Furthermore, some measures help prevent problems:
- Monitor your CPF on Registrato, a Central Bank system
- Do not share passwords or banking access
- File a police report in case of suspicion
- Use the “return” function for values received by mistake
What to do if you identify unauthorized account use
If there is suspicion, acting quickly is essential.
First, file a detailed police report. Then, consult Registrato to check financial links.
Additionally, notify the financial institution and request a block on suspicious transactions.
Finally, the guidance of a specialized lawyer is indispensable. In some cases, it is possible to prove victim status.
Financial impacts can last for years
Involvement in mule account cases generates prolonged consequences.
A name linked to investigations can block credit and prevent account opening.
Furthermore, legal defense costs can compromise family income, even when innocence is proven.
Therefore, protecting your bank account is essential. After all, is it worth taking such a high risk for a request made in a few seconds?
