The policy was revised to lower standards after the bank failed to meet them
Cedae approved Master Bank despite it failing to meet minimum credit rating requirements; audit shows policy was revised to lower standards after bank received BBB- rating. Negotiations began six days after banker Daniel Vorcaro's dinner with then-governor Cláudio Castro in New York, though auditors found no direct causal link.
- R$220 million in losses from Master Bank investments
- Policy revised in September 2023 to lower credit rating requirements after bank received BBB- rating in July
- First documented meeting between Master Bank and Cedae occurred May 17, 2023, six days after banker Daniel Vorcaro's dinner with then-governor Cláudio Castro in New York
- Master Bank entered extrajudicial liquidation in November 2025 after failing to repay scheduled funds
Internal audit of Rio's water company Cedae found R$220 million in losses from investments in Master Bank, with timeline suggesting political influence and policy manipulation to enable ineligible institution.
Rio's state water company, Cedae, lost R$220 million in a scheme centered on investments in Master Bank—a financial institution that should never have qualified for the money in the first place. An internal audit released this week reconstructed how it happened, laying bare a timeline of policy reversals, restricted information flows, and delayed warnings that went unheeded until the bank collapsed.
The mechanics were straightforward enough. In March 2023, Cedae's board approved an investment policy with clear guardrails: any bank receiving company funds had to carry a minimum credit rating of A- or better, verified by at least two independent rating agencies. By July, Master Bank submitted documents showing a BBB- rating from Fitch—a grade that should have disqualified it immediately under the rules just adopted. Instead of enforcing the policy, the company's financial leadership revised it in September, loosening the rating requirements and softening other risk thresholds. The audit found no legitimate business reason for the change.
What made the timing suspicious was what came before. Company records showed a meeting between Master Bank representatives and Cedae's financial directors on May 17, 2023—more than a month earlier than the company had told the Securities Commission it first made contact. That same month, Antonio Carlos dos Santos, then leading Cedae's financial operations, traveled to São Paulo with advisors to meet Maurício Quadrado, a co-founder and co-CEO of Master Bank. The audit noted that these early negotiations stayed locked within the financial directorate and a small circle of consultants, never shared with other departments that might have raised concerns.
The timing connected to something else: six days before that May 17 meeting, banker Daniel Vorcaro had hosted then-governor Cláudio Castro at a dinner in New York. Federal police are investigating that encounter as part of a broader inquiry now before Brazil's Supreme Court. The auditors were careful to say they found no direct link between the dinner and the subsequent investments. But the sequence was there in the record, impossible to ignore.
Once the money went in, warning signs accumulated. Starting in 2025, different departments within Cedae began flagging Master Bank's deteriorating finances and recommending the company reduce its exposure. The financial directorate moved slowly. When Cedae finally tried to recover all its funds in September 2025, Master Bank was already in liquidity crisis. In November, a scheduled repayment never arrived. The next day, Brazil's central bank ordered the bank into extrajudicial liquidation.
Dos Santos, the former financial director, issued a statement denying he had withheld information from the board. He said every step of the investment policy had been monitored by the full board, which received monthly reports on all financial placements. He expressed confidence that the facts would vindicate his management.
Castro, the former governor, said he had never interfered in Cedae's investment decisions. He noted that the policy changes followed proper internal procedures and were approved unanimously, and he denied any connection between the New York dinner and the bank investments.
Cedae's current leadership has removed the officials responsible for the Master Bank investments, reformed the investment policy, and stripped political appointees from the financial directorate and investor relations office. The company said it would pursue measures to establish final liability, calculate the definitive loss, and seek restitution from public coffers. The investigation into whether political pressure shaped these decisions continues.

La Conversación del Hearth Otra perspectiva de la historia
Why would a state water company be investing in a private bank at all?
That's the first question. Cedae manages cash reserves and needs to put money somewhere it earns returns. The problem wasn't the idea of investing—it was that they bent their own rules to put a quarter-billion reais into an institution that didn't meet their standards.
And the dinner in New York—do we know what was discussed?
The audit doesn't say. The Federal Police are investigating it. What matters for this story is the timing: six days later, Master Bank representatives walked into Cedae's offices for what the company claimed was a first meeting, but wasn't.
Why hide the earlier meetings from regulators?
That's what the audit is asking. If you're following proper procedure, you document everything from the start. Keeping early negotiations quiet, then revising your investment standards after the bank fails to meet them—that looks like you're working backward from a predetermined outcome.
Did anyone inside Cedae object while this was happening?
Not visibly, not in the documents the audit found. The financial directorate kept it compartmentalized. Other departments only learned about it later, and by then they started raising red flags about the bank's health. But by then the money was already committed.
What happens now?
Cedae's new management has fired the people involved and changed the rules. But the bigger question—whether a governor's dinner with a banker influenced a state company's investment decisions—that's still being investigated at the highest levels of the judiciary.
