Former CVM director Otto Lobo’s decisions favoring Banco Master draw scrutiny amidst his presidential nomination approval process in 2025

The nomination of Otto Lobo by President Luiz Inácio Lula da Silva to chair Brazil’s Securities and Exchange Commission (CVM) has brought to light past decisions made by Lobo as a CVM director that were reportedly favorable to Banco Master, a financial institution now under extrajudicial liquidation. Lobo, whose name was put forward to the Federal Senate for consideration, faces renewed scrutiny over his tenure. The CVM is a critical independent agency responsible for regulating Brazil’s capital markets.

These past actions, which occurred in at least two significant instances, have sparked debate regarding the impartiality and oversight within the regulatory body. The timing of the nomination, following these controversial decisions and ahead of 2025, amplifies the discussion within financial circles.

The incidents occurred while Lobo served as a CVM director, a position he has held since 2022 after being appointed by former President Jair Bolsonaro. His ascent to interim president, as the most senior director, preceded this recent presidential nomination, adding layers of complexity to his professional trajectory and the CVM’s leadership.

Ambipar OPA decision sparks controversy

One notable case involved the CVM’s analysis of whether Ambipar, an environmental services company, was obliged to conduct a Public Acquisition Offer (OPA) following a significant increase in shareholding. The CVM’s technical department had concluded that an OPA was indeed required, a position that was initially supported by then-CVM president João Pedro Nascimento.

However, in July of the preceding year, Otto Lobo, then a director, requested a review of the process. When the case returned to the plenary, Lobo presented an argument against the mandatory OPA, and his perspective ultimately prevailed within the collegiate body. This decision circumvented a potentially significant financial obligation for Ambipar.

The concern surrounding the OPA stemmed from fears that it could lead to a multi-billion Brazilian Reais disbursement. Such a massive outflow of capital would have put considerable strain on Ambipar’s cash flow and debt levels, potentially jeopardizing the company’s financiers. Among the primary creditors at risk was Banco Master, directly benefiting from the CVM’s decision to waive the OPA.

Alleged irregularities investigation sidelined

A second case concerned an investigation into alleged irregularities within investment funds linked to Banco Master and its principal, Daniel Vorcaro. To conclude these processes without a full judgment on their merits, the individuals under investigation presented a commitment agreement proposal to the CVM. This type of agreement allows for settlement without an admission of guilt, often involving fines or other compensatory measures.

During the internal proceedings, Otto Lobo once again requested a review of the process, effectively delaying its progress. The case remained off the agenda for several months following his intervention. This deferment prevented a timely resolution or judgment on the alleged malpractices.

The issue was only brought before the CVM’s plenary on December 2nd, by which time Banco Master had already been placed under extrajudicial liquidation. This timing meant that any potential judgments on the merits of the case became largely moot, raising questions about the efficacy and responsiveness of the regulatory process in protecting market integrity. CNN Brasil attempted to contact Otto Lobo for comment regarding these allegations, but received no response prior to the publication of initial reports.

Otto Lobo’s professional background and path to presidency

Otto Lobo’s tenure at the CVM began in 2022 when he was appointed as a director. His academic credentials include a doctorate in law from the University of São Paulo (USP), indicating a deep theoretical foundation in legal principles relevant to financial markets. Prior to his CVM directorship, Lobo also served as a full member counselor on the National Financial System Appeals Council (CRSFN) between 2015 and 2018, gaining experience in financial dispute resolution.

Following the resignation of João Pedro Nascimento, Lobo assumed the interim presidency of the CVM, a role he held due to being the most senior director within the autonomous agency. This progression highlights a continuous presence at the forefront of Brazil’s financial regulatory landscape, culminating in his recent nomination for the permanent leadership position.

The CVM operates as an autonomous special regime entity, reporting to the Ministry of Finance, and plays a crucial role in safeguarding the integrity and transparency of Brazil’s capital markets. Currently, the commission has two active directors, João Accioly and Marina Paula Copola. Lobo’s nomination will now be reviewed by the Federal Senate, and if approved, he is set to officially replace João Pedro Barroso do Nascimento, whose resignation from the CVM presidency was effective in July 2025. This process underscores the rigorous scrutiny applied to leadership roles in vital financial regulatory bodies.
