Brazil’s Banco Master collapse: entanglements ensnare top financial, judicial, and audit bodies

Brazil’s Central Bank officially decreed the extrajudicial liquidation of Banco Master and its associated entities in November 2025, citing a “severe liquidity crisis” and “grave violations” of National Financial System (SFN) regulations. This decisive action impacted Banco Master S/A, Banco Master de Investimento S/A, Banco Letsbank S/A, and Master S/A Corretora de Câmbio, Títulos e Valores Mobiliários, underscoring significant systemic risks despite the conglomerate holding a modest 0.57% of total SFN assets.

The move by the monetary authority, detailed in a public note at the time, highlighted a profound economic and financial instability within the Master Conglomerate. This immediate regulatory intervention sent ripples across the financial sector, revealing deep-seated issues that had evaded prior detection and threatened the broader stability of the SFN.

Simultaneously, the Federal Police launched “Operation Compliance Zero,” a large-scale investigation targeting the issuance of fraudulent credit titles by financial institutions. This operation culminated in the arrest of Daniel Vorcaro, Banco Master’s owner, on November 17, 2025, just one day before the Central Bank’s liquidation announcement, intensifying public scrutiny.

Central Bank’s swift action and its initial fallout

The Central Bank’s decree in November 2025 detailed how the grave liquidity crisis and the significant compromise of the Master Conglomerate’s economic-financial situation, coupled with severe violations of SFN norms, necessitated the extraordinary liquidation regime. This measure was implemented to mitigate further risks to the national financial system.

At the time of its liquidation, the Banco Master conglomerate represented a small but interconnected portion of the SFN, accounting for 0.57% of total assets and 0.55% of total deposits. The decision to liquidate was seen by many market analysts as a necessary but dramatic step to uphold regulatory integrity.

Owner’s arrest, release, and Supreme Court’s controversial intervention

Daniel Vorcaro, the owner of Banco Master, was apprehended on November 17, 2025, as part of the Federal Police’s “Operation Compliance Zero,” which specifically aimed to combat the illicit issuance of fake credit securities within the financial system. His arrest underscored the severity of the alleged fraudulent activities preceding the bank’s collapse.

Despite the initial detention, Vorcaro was released less than two weeks later, fitted with an electronic ankle monitor, after a Federal Regional Court (TRF) judge revoked his preventive imprisonment. This rapid reversal raised eyebrows regarding the judicial process surrounding the high-profile case.

The legal landscape shifted dramatically in early December 2025 when Minister Dias Toffoli of the Supreme Federal Court (STF) accepted Vorcaro’s defense request, bringing the entire case under the Supreme Court’s jurisdiction. This meant all future investigations and legal proceedings would be subject to the STF’s oversight, bypassing lower courts entirely.

Allegations of influence and judicial entanglements

The Supreme Court’s involvement quickly drew further controversy when reports emerged of Minister Toffoli traveling on a private jet to Lima with one of Vorcaro’s defense lawyers between November 28 and 30, 2025, ostensibly to attend the Copa Libertadores final. This proximity between a Supreme Court minister and a key legal figure in a high-stakes case ignited a public debate about judicial ethics and impartiality.

Following his return to Brasília, Minister Toffoli imposed a strict confidentiality regime on the investigation, which primarily focused on Daniel Vorcaro. This move, coming shortly after his contentious trip, intensified scrutiny from both the media and the public regarding the transparency of the proceedings.

Adding another layer of complexity, it was revealed that the law firm of Minister Alexandre de Moraes’s wife, Viviane Barci de Moraes, held a substantial R$129 million contract with Banco Master, entailing monthly payments of R$3.6 million between 2024 and 2027. With the bank’s liquidation, these payments were abruptly halted, drawing attention to potential conflicts of interest.

Further allegations surfaced in December 2025, with reports indicating that Minister Moraes had contacted Gabriel Galípolo, the president of the Central Bank, at least four times to discuss matters related to Banco Master. Moraes later clarified that his meetings and calls with Galípolo were primarily to discuss the implications of the Magnitsky Act sanctions against him and his wife, emphatically denying any pressure regarding the BRB-Master acquisition.

BRB’s failed acquisition and fraud allegations

In March 2025, the Banco de Brasília (BRB) announced its board’s approval to acquire a significant stake in Banco Master, specifically 49% of ordinary shares, 100% of preferred shares, totaling 58% of the Master’s capital. This acquisition, valued at approximately R$23 billion in assets, would have granted BRB substantial control and voting rights.

However, the Central Bank vetoed the proposed acquisition in September 2025, citing “excessive risks” and a misalignment between Banco Master’s assets and BRB’s operational profile and clientele. This regulatory rejection ultimately prevented a potential merger that could have altered the fate of Banco Master. Later investigations by the Federal Police and the Public Prosecutor’s Office began to explore whether BRB had acquired credit portfolios from Banco Master in a manner designed to stave off its liquidity crisis, potentially through “underhanded procedures” and “pure camaraderie,” contradicting formal contractual instruments, with an estimated fraud value of R$12.2 billion. The findings led to the removal of BRB’s then-president, Paulo Henrique Costa, and financial executive director, Dario Oswaldo Garcia Junior, while a new management initiated an audit to investigate the irregularities.

TCU scrutinizes Central Bank’s regulatory oversight

The liquidation of Banco Master also triggered an inquiry by the Federal Court of Accounts (TCU), following a request in November 2025 from the Public Prosecutor’s Office alongside the TCU. The request aimed to ascertain whether the Central Bank had failed or been negligent in its supervision and oversight of Banco Master and its subsidiaries, opening a new front in the regulatory and judicial saga.

TCU Minister Jhonatan de Jesus subsequently set a deadline for the Central Bank to provide the technical-legal justifications for the extrajudicial liquidation. Although the Central Bank submitted a detailed timeline of its actions from 2023 leading to the final intervention decision by late December 2025, the Tribunal deemed these explanations insufficient. Consequently, the TCU ordered an inspection of the monetary authority to address identified omissions and clarify lingering doubts.

Facing increased pressure, the Central Bank filed an appeal with the TCU, challenging Minister Jhonatan de Jesus’s unilateral decision to conduct an inspection. In response, Minister de Jesus adjusted his stance, directing that the inspection be submitted to the full plenary of the Court, with the first session of 2026 scheduled for January 19. The unfolding controversy at the TCU drew strong reactions from the financial sector, with market agents defending the Central Bank’s autonomy in supervising the financial system, arguing against what they perceived as an overreach by the TCU into private financial matters, including assets tied to Daniel Vorcaro.

Broader implications for financial oversight

The complex interplay between the Central Bank, the Supreme Court, and the Federal Court of Accounts in the Banco Master case highlights significant challenges in Brazil’s financial regulatory landscape. Each institution’s actions, while distinct, converge on the need for transparency, accountability, and the maintenance of systemic stability. The ongoing investigations and legal proceedings are critical in shaping future regulatory frameworks and reinforcing public trust in the integrity of the nation’s financial and judicial systems.
