Brazil’s securities regulator opened a sanctioning process against Banco do Brasil’s CEO and finance vice president over allegedly overly positive statements. The case stems from remarks at the second-quarter 2025 earnings presentation.
Brazil’s securities regulator, the CVM, has opened a sanctioning process against Banco do Brasil’s chief executive, Tarciana Medeiros, and its investor relations vice president, Marco Geovanne Tobias da Silva. The regulator alleges they gave “excessively positive” statements that could mislead investors, according to O Globo’s Capital column, carried by Estadao Conteudo on 17 August 2026.
Banco do Brasil: What is a CVM sanctioning process?
A processo administrativo sancionador is a formal administrative sanctioning process under CVM rules. It is used to investigate and potentially punish disclosure-related misconduct by issuers and executives, and it is not a criminal proceeding.
After the investigative phase, the accusation is now subject to judgment. If a violation is found, penalties range from fines to disqualification, but none imposed yet.
The statements at issue
The case involves a remark Medeiros made during the second-quarter 2025 results presentation, not an interview. She said, “Whoever has BB shares, keep them; whoever doesn’t, buy them,” and added, “Wait for 2025, we will deliver to the market what we propose to deliver, and 2026 is a year of recovery.”
The CVM’s technical area sought clarifications then, and the accusation was formulated a year later. As of 17 August 2026, Medeiros had not been formally notified, though that was expected in the coming days.

Second-quarter financials behind the case
Banco do Brasil reported Q2 2026 adjusted net income of R$3.9 billion, up 3.3% YoY and 13.9% QoQ. Cost of credit totaled R$18.5 billion, down 2.1% QoQ but up 16.1% YoY.
The bank’s 90-day NPL ratio was 5.61% at end-June, up from 5.05% in March and 3.96% a year earlier. Agribusiness NPL hit 6.27%, up from 6.22% in March and 3.16% a year prior.
The agribusiness loan book reached R$421.6 billion. Higher delinquency in rural operations drove the rise in credit costs.
Guidance cut and management’s position
On 13 May 2026, Banco do Brasil cut guidance: adjusted net income lowered from R$22-26B to R$18-22B. Cost of credit forecast raised from R$53-58B to R$65-70B.
Management maintained those ranges at the second-quarter results. The bank expects cost of credit to reach the higher end of the range, while profit trends toward the lower end.
First-half cost of credit was R$37.3 billion, and first-half net income fell 34.2% year over year to R$7.3 billion. Results for the quarter were released on 12 August 2026.
Share price context
On 17 August 2026, Banco do Brasil shares closed at R$17.95, down R$0.43 or 2.34% from R$18.38, at the day’s low. Stock is down 13.08% over twelve months, per stockanalysis.com.
The 52-week range spans from R$17.80 to R$27.74, according to Investing.com. The share price has been under pressure from rising credit costs and delinquency.
Bank’s defense and next steps
Banco do Brasil said it will provide clarifications to the CVM once it has access to the full case file. The bank argues the remarks must be read in the full context of the earnings presentation, not as isolated excerpts.
The bank says there was no intention to steer investment decisions or influence the share price. The statements rested on already-disclosed information, according to the bank.
Medeiros has not issued a personal statement on the CVM charges. The process is early, may take months or years, and executives may present their defense.
