A New Character Emerges in the Master Case

As the Federal Police investigations advance, one of the names expected to appear more frequently in the Master Case is Diego Maciel, the former commercial superintendent of the bank in Rio de Janeiro. According to the report, Maciel acted on behalf of Daniel Vorcaro in dealings with members of the Rio de Janeiro state government during the administration of Governor Cláudio Castro. His contacts allegedly included state secretaries and executives from state-linked entities such as Cedae, the state water and sanitation company, and Rioprevidência, the state pension fund.

Maciel is specifically mentioned in an audit report prepared by Cedae. The document states that he took part in a meeting on May 17, 2023, between representatives of Banco Master and members of Cedae’s Financial Directorate. The meeting is cited as part of a broader pattern of interactions between the bank and public officials or state-controlled institutions in Rio de Janeiro.

The report also notes that the Cláudio Castro government authorized a total of R$ 4 billion in investments in Banco Master. This figure is likely to draw further scrutiny as the investigation develops, given the scale of the amount and the involvement of public entities.

The emerging focus on Maciel suggests that investigators are examining not only the bank’s internal decision-making but also the network of relationships used to secure access to government officials and state investment channels. The case may expand as authorities review meetings, approvals, and institutional contacts linked to the bank’s operations in Rio de Janeiro.

With the PF’s inquiry moving forward, the role of intermediaries between Banco Master and the state administration appears to be becoming a central element of the investigation. The mention of Maciel in the Cedae audit adds another layer to the scrutiny surrounding how the bank engaged with public-sector actors and how investment decisions were made.
