Brazil’s Federal Police served six search-and-seizure warrants in Campo Grande, Mato Grosso do Sul, on Tuesday 25 August 2026, in a Banco Master pension probe targeting the city’s municipal retirement fund. Investigators are examining roughly R$1.2 million (about US$233,000) placed in Banco Master, the lender liquidated in November 2025.
Police Raid Municipal Offices in Campo Grande Pension Investigation
Federal Police officers fanned out across Campo Grande, the capital of Mato Grosso do Sul, on the morning of Tuesday 25 August 2026 to execute six search-and-seizure warrants. The warrants were served at the municipal pension institute, the social assistance secretariat and the homes of investigated public servants, and one of the targets is the city’s vice-mayor, Camilla Nascimento, a former director of the pension fund.
The target of the operation is the Instituto Municipal de Previdência de Campo Grande, known by its acronym IMPCG, which manages retirement savings for the city’s public employees. Investigators are examining roughly R$1.2 million (about US$233,000) that the fund placed with Banco Master, though one local outlet, Campo Grande News, puts the updated value of the investment at about R$1.43 million (about US$278,000).
Banco Master was liquidated in November 2025, and the money parked there by institutional investors has been in doubt ever since. The probe alleges gestão temerária, a Portuguese legal term meaning reckless management, alongside corruption in the way the pension fund’s investment decisions were made.
Officers seized documents and records intended to reconstruct who authorised the investment, on what terms, and with what internal checks. The operation was reported by Brazilian outlets including G1 and Gazeta do Povo, which tracked the police movements through the city during the day.
The investment at the heart of the case was made in April 2024, when the fund bought a financial note, known as a Letra Financeira, from Banco Master that was due to mature only in April 2029. After the bank’s liquidation, the fund went to court and in March 2026 recovered the original investment plus monetary correction through a judicial offset against payroll-loan payments, according to Campo Grande News. The Federal Police operation, named Operação Presciência, was authorised by the third federal court in Campo Grande and investigates possible reckless management, passive corruption and active corruption.
Raid Forms Part of National Sweep of Municipal Pension Funds
The Campo Grande operation is not an isolated case. The Banco Master pension probe forms part of a national sweep over Banco Master investments made by municipal pension funds, known in Brazil by the acronym RPPS, the regimes that manage retirement savings for public-sector employees outside the main social security system.
The investigation in Mato Grosso do Sul is one front in that wider effort. Municipal funds in several states placed money with the bank before its collapse, and federal investigators are now working through those exposures city by city to determine how the decisions were made.
The bank’s liquidation in November 2025 turned what had been a financial story into a criminal and political one, because the losses sit in funds that pay the pensions of teachers, clerks and other local government workers. Each new warrant raises the pressure on fund managers and municipal officials who approved the placements.
For Campo Grande, the immediate question is how much of the IMPCG exposure can be recovered for the municipal workers whose retirements depend on the fund, and whether anyone will be held personally responsible for the decision to invest.
OSX Creditors Approve Judicial Recovery Plan
In a separate corporate development, creditors of OSX Brasil approved the company’s judicial recovery plan at a general assembly held on Monday 24 August 2026, with the outcome reported the following day. The vote had been suspended twice, moving from 3 August to 17 August before finally concluding on 24 August.
The plan won the backing of 82.6 percent of Class III creditors, the unsecured group that typically faces the steepest losses in a restructuring, and 100 percent of Class IV creditors. The vote was not unanimous: labour creditors in Class I registered no votes in favour, the company said, but support from the other classes still allows the plan to be submitted for court confirmation.
The plan restructures approximately R$7.5 billion (about US$1.46 billion) in debt. It still requires homologation, the formal confirmation by the Rio de Janeiro court overseeing the case, before it takes full effect.
OSX, which trades under the ticker OSXB3, is the shipbuilding company founded by businessman Eike Batista. It has been in judicial recovery in Rio de Janeiro since January 2024, and the creditor vote marks its most important step yet toward emerging from the process. The company said the minutes of the assembly, together with its annexes, had not yet been published given the number of matters decided, and would be released to the market as soon as they are available.
Halliburton Wins Services Contract for BP Bumerangue Appraisal
Halliburton has signed a contract to provide services for BP’s three-well appraisal campaign on the Bumerangue field, Valor reported on 25 August 2026. Bumerangue, in the pre-salt Santos Basin off the coast of Rio de Janeiro state, is BP’s biggest discovery in 25 years. The contract covers integrated drilling services intended to speed up the delineation and appraisal programme, and Halliburton said it will deploy software, artificial intelligence and advanced drilling technologies to support BP’s decisions from planning through well evaluation.
The field sits 404 kilometres offshore in water 2,372 metres deep, placing it among the more demanding environments in Brazilian exploration. BP holds 100 percent of the block, with Pré-Sal Petróleo acting as manager of the production-sharing contract.
Appraisal drilling is expected to begin in late 2026 or early 2027, and BP is targeting completion of the campaign by the end of the first half of 2027. The timeline was set out by Felipe Arbelaez, BP’s senior vice president for upstream in Brazil, in comments carried by Reuters.
For Halliburton, the award puts the services company at the centre of BP’s effort to define the size and commercial potential of its largest find in a quarter-century, a project that will be closely watched across Brazil’s offshore industry.
What Comes Next in the Three Cases
In Campo Grande, the Banco Master pension probe now turns to the material seized on Tuesday, which will guide the next phase of the investigation into the IMPCG investment and any decisions that followed it.
For OSX, attention shifts to the Rio de Janeiro court, which must decide whether to homologate the recovery plan that creditors approved after three attempts at holding the assembly vote.
For BP and Halliburton, the focus moves to mobilising rigs, equipment and crews for appraisal drilling at Bumerangue, with the first wells expected around the turn of the year.
Taken together, the three stories capture a single day’s cross-currents in Brazil: a crackdown on pension-fund exposure to a failed bank, a corporate rescue edging toward completion, and fresh investment flowing into the country’s pre-salt oil frontier.
