Brazil's Federal Police carried out an operation on July 9 focused on Thiago Miranda, an executive contracted by banker Daniel Vorcaro to run a communications campaign defending Banco Master. A Supreme Court ruling said investigators suspect Miranda of hiring influencers to attack the central bank, assembling information on targets including the CEO of Itau Unibanco and a prominent journalist, and of attempting to intimidate reporters and unlawfully monitor individuals.

Key Points

  • Federal Police executed a court-authorized operation targeting Thiago Miranda, who was hired by banker Daniel Vorcaro to manage a communications campaign defending Banco Master.
  • Justice Andre Mendonca authorized seizure of electronic devices, documents, accounting records, cash and other material from multiple addresses linked to Miranda; investigators allege he hired influencers and compiled dossiers on targets including Itau Unibanco's CEO and a prominent journalist.
  • The probe follows Vorcaro's March arrest after Brazil's central bank liquidated Banco Master last year due to a liquidity crisis; the case affects the banking sector and raises concerns for media and legal oversight.

BRASILIA, July 9 - Federal Police launched a targeted operation on executive Thiago Miranda after a court ruling tied him to a communications campaign organized on behalf of the now-defunct lender Banco Master. The court document, issued on Thursday by Supreme Court Justice Andre Mendonca, says Miranda had been hired by banker Daniel Vorcaro to coordinate public messaging defending the collapsed institution.

The operation represents the latest development in an expanding probe into the bank's failure. Vorcaro was arrested in March after Brazil's central bank moved to liquidate Banco Master last year following a liquidity crisis. The case has revealed what authorities describe as a network of influence and has raised questions about public trust in officials.

According to Justice Mendonca's ruling, police suspicions underpinning Thursday's actions included coordinated attacks on the central bank and the preparation of a dossier on Milton Maluhy Filho, the CEO of lender Itau Unibanco. The judge approved seizure orders for electronic devices - including computers and cell phones - as well as documents, accounting records, cash and other evidence found at multiple addresses linked to Miranda.

Mendonca's decision notes investigators located evidence indicating Miranda had arranged for influencers to defend Banco Master while criticizing the central bank. The ruling also states Miranda may have been involved in efforts to intimidate journalists and in unlawful monitoring of certain individuals.

Prior to the operation, Miranda - the owner of a communications agency - had been treated by authorities as a witness in the Master investigation. He had provided officials with information regarding Vorcaro's earlier attempts to publicly defend the lender. However, messages exchanged between Miranda and Vorcaro prompted investigators to reassess Miranda's role.

Those communications led authorities to conclude Miranda was responsible for collecting information on some of Vorcaro's targets, among them the Itau Unibanco CEO and a noted journalist. Reuters was unable to reach Miranda for comment and investigators could not identify or contact his legal representatives. Itau declined to comment on the matter.


Context and next steps

The court-authorized seizures aim to secure digital and physical records for further forensic review. The investigation remains ongoing and the court ruling frames Miranda as a central figure in the communications dimension of the probe.

Risks

  • Allegations of attempted intimidation of journalists and unlawful monitoring could further strain trust in public institutions and affect media-sector relations with financial entities - impact relevant to the media and legal sectors.
  • Public allegations and the widening investigation may erode confidence in the banking sector, particularly among stakeholders connected to Banco Master and other lenders, heightening scrutiny on financial firms and regulators.
  • Seizures of documents and electronic records indicate a protracted legal process; prolonged uncertainty could influence perceptions of governance and oversight in finance and communications industries.
