NextFin News - In a decisive move that reshapes the trajectory of one of Brazil’s most sensitive financial investigations, Supreme Court Justice André Mendonça has authorized the Federal Police (PF) to conduct unrestricted expert analysis and investigative procedures in the ongoing Banco Master case. The ruling, issued late Thursday, February 19, 2026, effectively dismantles the procedural barriers previously established by the former rapporteur, Justice Dias Toffoli. According to O Globo, Mendonça’s decision allows the PF to carry out routine investigative acts, including the interrogation of suspects and witnesses, while significantly easing confidentiality restrictions that had hampered the flow of information between internal law enforcement units.
The "Master Case" centers on allegations of massive financial irregularities and a liquidity crisis that led the Central Bank of Brazil to determine the extrajudicial liquidation of Banco Master S/A and its affiliates in November 2025. The investigation gained international attention due to the scale of the potential fraud—estimated to involve R$40.6 billion in guarantees from the Credit Guarantee Fund (FGC)—and the political tremors it has sent through the Brazilian judiciary. The shift in rapporteurship occurred after Toffoli recused himself following reports from the PF that mentioned his name in messages extracted from the cell phone of Daniel Vorcaro, the owner of Banco Master. While Toffoli has denied any wrongdoing or intimate friendship with Vorcaro, the appearance of a conflict of interest forced a redistribution of the case, which fell to Mendonça by lottery.
Mendonça’s intervention marks a significant departure from the previous judicial stance. By granting the PF "unrestricted" access, the Justice is addressing a core grievance of investigators who felt the probe was being stifled by top-down judicial management. The analysis will now focus on the extraction of data from Vorcaro’s devices and the mapping of financial flows that allegedly involved Bank Deposit Certificates (CDBs) offering returns far above market rates—a practice investigators believe was used to mask a deteriorating balance sheet. The Federal Police are now empowered to share these findings internally without the granular, case-by-case authorization that had slowed the process under the previous rapporteur.
From a financial stability perspective, the Banco Master collapse represents the most significant crisis in the Brazilian banking system in recent years. The institution’s digital arm, Will Bank, was also swept into the turmoil, impacting millions of retail customers. Analysts suggest that the unrestricted nature of the new expert analysis will likely uncover the extent to which the bank used structured operations to artificially inflate its assets. The involvement of the FGC to cover R$40.6 billion in deposits highlights the systemic risk that was allowed to build up under the radar of traditional regulatory oversight, raising questions about the efficacy of the Central Bank’s monitoring during the 2024-2025 period.
The geopolitical implications are also noteworthy. As U.S. President Trump continues to emphasize financial transparency and the rule of law in Western Hemisphere trade relations, the integrity of Brazil’s judicial and financial systems remains a key metric for foreign investment. The "Master Case" has become a litmus test for whether Brazil’s institutions can investigate high-level corruption without political interference. Mendonça, who was appointed to the court during the Jair Bolsonaro administration and has maintained ties to evangelical circles, now faces the challenge of demonstrating total independence, particularly given the alleged connections between certain pastors and Vorcaro’s conglomerate.
Looking forward, the unrestricted access granted to the PF suggests that the investigation will move into a more aggressive phase. The next 90 days will be critical as the police finalize their report on the digital evidence. If the analysis confirms that the bank’s leadership engaged in deliberate fraud to deceive regulators and investors, it could lead to a wave of indictments reaching into the upper echelons of Brazil’s business and political elite. Furthermore, Mendonça must still decide whether the case will remain under the Supreme Court’s jurisdiction or be sent to a lower court, a decision that will dictate the speed and public visibility of the eventual trial. For now, the restoration of police autonomy serves as a stabilizing signal to markets that the rule of law is being prioritized over institutional protectionism.
