E-mails obtained by Brazil’s Federal Police indicate that Flávio Bolsonaro, the conservative frontrunner for president, shared a Santander bank account with a lawyer suspected of laundering money from a pension fraud. The Flávio Bolsonaro bank account story broke on Saturday 10 October, 15 days before the runoff against President Luiz Inácio Lula da Silva. It matters abroad because markets, and the bets US traders follow, already treat Flávio as the likely next leader of Latin America’s largest economy.
Both men deny it. Flávio calls the report fake news timed for the election. The lawyer, Willer Tomaz, says the two are friends with no financial ties. Nothing in the reporting so far says Flávio is formally under investigation.
What the Emails Show
The news site UOL published the e-mails first. Folha de S.Paulo said it confirmed them, and CNN Brasil said police sources confirmed the find to its reporters.
According to Folha, one exchange was between an employee of Tomaz and Santander. It concerned an account linked to Alcazar Holdings, a company based on the Portuguese island of Madeira in which Tomaz is a partner.
In May 2025, the employee asked the bank to remove Flávio Bolsonaro from that account. CNN Brasil reported the same detail: a request for the senator to be “disassociated” from an account belonging to a company of the lawyer.
CNN Brasil said the e-mails were found during a police search and seizure. It added that the Federal Police are now looking into whether the two shared an account, within the existing inquiry into pension fraud.
The underlying records have not been published. It is not clear whether Flávio was a full account holder, an authorised user, or only listed on paper.

Who Is Willer Tomaz
Tomaz is a Brasília lawyer and businessman with friends across the political spectrum, Folha reports. That includes Flávio and members of Lula’s governing coalition.
In August he was one of the targets of a phase of Operation Sem Desconto (“No Deduction”), Folha says, together with relatives of Senator Weverton Rocha. Rocha represents Maranhão for the PDT, a centre-left party in Lula’s camp.
The operation investigates unauthorised deductions taken from the pensions of retirees paid by the INSS, Brazil’s National Social Security Institute. On Tuesday 4 August the police said they were serving 18 search warrants, issued by the Supreme Federal Court, in the Federal District and Maranhão. That phase targeted suspected money laundering through third-party accounts, companies and cash.
CNN Brasil adds that Tomaz co-owns an aircraft on which Flávio flew in January 2025. The plane was managed by a company linked to Daniel Vorcaro, the former owner of Banco Master, a bank at the centre of another large police case.
Tomaz was arrested in 2017 in Operation Patmos, which grew out of the plea deal of the meatpacker JBS. Prosecutors accused him of helping to leak confidential information. A court rejected the charges.
What Both Sides Say
Flávio’s press office said he “never held an account in which Mr Willer Tomaz or any of his companies was the master user.” It called every claim to the contrary false.
It said the reports appeared “in the middle of the election period” to spread fake news. It warned that spreading fake news is an electoral crime and that those responsible would face criminal action.
Tomaz’s office denied sharing any account with the senator. “Between the two there is only friendship, with no commercial or financial relationship,” it said. His lawyers said they had filed a criminal complaint over the publication.
Tomaz’s office also said the Federal Police had opened an inquiry into the leak of the sealed material. That claim comes from his side and has not been confirmed by the police.
What It Means for You
For US investors, Brazil’s runoff is the main political event of the quarter. Brazilian shares and ADRs trade in New York, and many funds are positioned for a change of government.
A scandal that stuck could narrow Flávio’s lead and add volatility in the last two weeks. So far there is little sign of that: the betting odds barely moved after the report.
The stabiliser is that the evidence on the Flávio Bolsonaro bank account is still thin. There is no charge, no formal suspect status and no public bank record. Voters, and markets, will judge the denials against whatever the police do next.
Brazilian retirees are the other audience. The INSS fraud hit pensioners directly, which gives any link to it more political weight than a typical corruption story.
What Is Not Known
It is not known what role, if any, he had on the Flávio Bolsonaro bank account named in the e-mails, when it was opened, or what money passed through it. The e-mails, as reported, show only a request to remove his name.
The Federal Police have made no public statement on the e-mails. It is not known whether they will ask the Supreme Court for permission to investigate a sitting senator.
Santander has not commented in the reporting reviewed. Alcazar Holdings’ activities and accounts have not been disclosed.
