Following Operation Hidden Carbon , which targeted the use of gas stations and financial institutions to launder money from organized crime, Brazilian banks will adopt new rules to cancel betting sites operating without authorization from the Ministry of Finance and accounts with suspicious transactions held in the names of straw men—when an account is opened in one person’s name but used by another to hide the origin of the money.
What happened
Banks cannot allow the opening and maintenance of dummy accounts, cold accounts, and illegal betting accounts, and that is why we are establishing mandatory procedures for all banks to regulate the sector and curb this type of crime. -Isaac Sidney, president of Febraban.

Here’s what banks will need to do:
1.Policies for verifying fraudulent accounts and accounts used by illegal betting sites;
2.Reporting fraud to the Central Bank with the sharing of information between banks;
3.Supervision by Febraban, which may request evidence regarding the closure of illegal accounts;
4.Refusal of suspicious transactions and closure of illicit accounts, with notification to the account owner;
5.Active participation from banking sectors dedicated to fraud prevention, money laundering, legal matters, and ombudsman services;
6.Banks must submit a statement of compliance to Febraban, prepared by an independent area, such as internal audit, compliance, or internal control.
Hidden Carbon
The announcement relates to Operation Hidden Carbon, a Federal Police investigation against the PCC (Primeiro Comando da Capital). The investigation dismantled a money laundering scheme involving gas stations and fintech companies . More than 350 people and companies were suspected, and 15 were the targets of search and arrest warrants.
