The Banco Master scandal widened sharply on May 7 as multiple converging fronts drew in the Centrão political bloc, the Bolsonaro family, and global stablecoin issuer Tether, just one day after Federal Police raided Senator Ciro Nogueira (PP-PI) in the fifth phase of Operação Compliance Zero.
Tether is suing Daniel Vorcaro’s Titan Holding for approximately R$1.6 billion (US$325M) in São Paulo’s courts over an unpaid US$300 million loan from March 2025, while Civil Police separately raided BRB employees over an unrelated R$15 million (US$3.05M) fraud, and senators demanded Justice Nunes Marques recuse from the CPI Master rapporteur role over Ciro proximity. The Planalto ordered cabinet ministers to stay silent on the raid.
Key Points
— Tether sues Titan Holding for R$1.6B (US$325M) on a March 2025 US$300M loan default.
— BRB Civil Police operation: R$15M (US$3.05M) suspicious transfers, luxury vehicles seized.
— Senators ask Nunes Marques to leave CPI Master rapporteur role over Ciro proximity.
— Tereza Cristina (PP Senate leader) defends investigations; Flávio Bolsonaro calls action “grave”.
— Planalto ordered cabinet ministers to remain silent on the Ciro Nogueira raid.
The Tether Filing
The Rio Times, the Latin American financial news outlet, reports that Tether filed in São Paulo state court to recover approximately R$1.6 billion (US$325M) tied to a US$300 million loan extended in March 2025 to Titan Holding (Daniel Vorcaro’s personal investment vehicle) with a 12-month maturity, naming Master Holding Financeira and Master Participações as additional debtors. The collateral included Banco Master consignado credit portfolios, with Tether now seeking those receivables plus broader asset-attachment if the primary security proves insufficient. Tether stated the financing was extended before public knowledge of irregularities at the Master conglomerate, and the suit cites Titan directors Luiz Antônio Bull and Ângelo Antônio Ribeiro da Silva (long-time Vorcaro associates) as legal representatives, while not naming Vorcaro directly.
In parallel, Brasília Civil Police raided BRB employees on May 7 over a separate R$15 million (US$3.05M) scheme involving suspicious transfers, cash operations, and luxury-vehicle asset concealment that the bank itself flagged. Civil Police clarified the action has no connection to the Master case or BRB’s earlier R$12 billion (US$2.44B) failed Master acquisition. One investigated employee allegedly intermediated three asset portfolios worth more than R$60 million (US$12.2M) and received income inconsistent with declared earnings, with possible irregularities at BRB DTVM (the bank’s securities arm) also under examination.
Centrão and Bolsonaro Reactions
Senators including PSDB and Rede members formally requested STF Justice Kassio Nunes Marques to step down from rapporteurship of the CPI Master action over his proximity to Ciro Nogueira, including past family-event attendance. Tereza Cristina, the PP Senate leader, defended the investigations as legitimate but signaled uncertainty about 2026 electoral fallout, while Flávio Bolsonaro (PL-RJ) called the Ciro raid “grave” but is privately distancing himself from the Centrão alliance. Governor Romeu Zema (Novo-MG) attacked Lula’s silence on the Master operation, prompting the Planalto to issue an internal directive ordering all cabinet ministers to refrain from public comment on the Ciro Nogueira raid.
PEC 65 and Vorcaro Plea Bargain
The May 6 raids targeted Senator Ciro Nogueira and his cousin Felipe Cançado Vorcaro (a former Master executive) over alleged corruption tied to PEC 65/2023, a constitutional amendment that would have provided regulatory cover for the Master conglomerate, with Daniel Vorcaro currently negotiating a plea bargain with PGR. The cumulative Master-Will Bank financial hole approaches R$47 billion (US$9.55B) in FGC liabilities. Daily life for the Centrão alliance is now dominated by which executives, donors, and lobbyists may be cited in upcoming PF phases, with the 2026 electoral calendar adding political urgency to every disclosure.

Frequently Asked Questions
What is Tether claiming?
Tether, the world’s largest stablecoin issuer (USDT, with over US$140B in market cap), filed in São Paulo state court to recover approximately R$1.6 billion (US$325M) tied to a US$300 million loan extended in March 2025 to Titan Holding, Daniel Vorcaro’s personal investment vehicle, with a 12-month maturity. The suit names Master Holding Financeira and Master Participações as additional debtors and is backed by Banco Master consignado credit portfolios as collateral. Tether stated the financing was extended before public knowledge of irregularities at the Master conglomerate.
Is the BRB R$15M case linked to Master?
No, Brasília’s Civil Police clarified the May 7 BRB action is unrelated to the Master case or BRB’s earlier R$12 billion (US$2.44B) failed Master acquisition. The R$15M (US$3.05M) scheme involves suspicious transfers, cash operations, and luxury-vehicle asset concealment that BRB flagged internally, with one investigated employee allegedly intermediating three asset portfolios worth more than R$60M (US$12.2M) and receiving income inconsistent with declared earnings. Possible irregularities at BRB DTVM (the bank’s securities arm) are also under separate examination.
Why does the Nunes Marques challenge matter?
A group of senators including PSDB and Rede members formally requested STF Justice Kassio Nunes Marques on May 7 to step down from rapporteurship of the CPI Master action, citing his proximity to Senator Ciro Nogueira, including past family-event attendance. The challenge is significant because the rapporteur shapes the legal trajectory of the case, including which evidence is admitted and what relief the CPI can seek. With Ciro now a target of the May 6 fifth phase of Operação Compliance Zero, the appearance of impartiality is critical to the credibility of the parallel STF investigations.
What about the Bolsonaro family?
Senator Flávio Bolsonaro (PL-RJ), the eldest son of former president Jair Bolsonaro, called the Ciro Nogueira raid “grave” but is privately distancing himself from the Centrão alliance, with a Bolsonarista allies trying to wedge Flávio away from Ciro. The Master scandal threatens to taint a potential 2026 PL-PP-União Brasil opposition coalition. Tereza Cristina (PP Senate leader) defended the investigations as legitimate while signaling uncertainty about 2026 electoral fallout.
