The Brasília Bank (BRB) submitted a report to the Financial Activities Control Council (COAF) at the end of 2025, highlighting suspicious transactions involving Banco Master, associated with businessman Daniel Vorcaro. These suspicious activities were documented in a three-part report filed on November 18, just one day after Vorcaro was arrested at Guarulhos International Airport while attempting to board a flight to Dubai. This timeline indicates a critical juncture in the investigations surrounding Vorcaro and his banking activities.

According to the report, the relationship between BRB and Banco Master dates back to 2021 and became more pronounced throughout 2024 and 2025. Despite an ongoing association for several years, this report to COAF marked the first time BRB raised concerns about potentially illegal financial activities. This delayed communication raises questions about the internal controls and compliance measures within BRB that may have allowed such movements to go unnoticed until the arrest of Vorcaro.

The COAF plays a vital role in Brazil's efforts to combat money laundering and is responsible for monitoring and reporting suspicious financial activities. In the report submitted by BRB, it stated that it identified movements that were inconsistent with Vorcaro's economic profile. This situation underscores the increasing scrutiny of financial institutions and reinforces the importance of proactive reporting in the prevention of financial crimes, particularly in light of the interconnectedness of financial entities as evidenced by the relationship between BRB and Banco Master.
