Shares in BRB, the bank owned by Brazil’s Federal District, no longer trade continuously. B3 moved them to auction-only dealing from Monday 31 August 2026.
The stated reason is that BRB has not delivered its financial statements. It has not published any since those for the second quarter of 2025.
What Changed on the Exchange
BRB’s securities now sit in auction for the whole session. Orders are registered through the day and matched only when the auction closes at the end of it.
B3 stresses this is neither a suspension nor a delisting. The shares still trade; they simply do not trade continuously.
The exchange said continuous trading returns once the company is up to date with all its periodic information. It set no deadline.
B3 applied the same measure to Ambipar from the same date, for the same kind of reason. The two cases are unrelated.
How Far Behind BRB Is
The last financial statement BRB filed with Brazil’s securities regulator covers the second quarter of 2025. It arrived on 29 August 2025.
Four filings are now overdue. They are the third-quarter 2025 statement, the full-year 2025 accounts, and the first and second quarters of 2026.
The oldest of those was due in November 2025, which makes it more than nine months late. BRB’s own results page shows dashes where the figures should be.
The bank confirmed in April 2026 that it had postponed the late-2025 statements. It cited a forensic audit connected to a federal police investigation.
Why the Accounts Stopped
In March 2025 BRB agreed to buy 49% of Banco Master’s voting shares and all of its preferred shares. That came to 58% of the company for about 2 billion reais.
Brazil’s central bank rejected the deal on 3 September 2025, after about five months of analysis. It then moved against Master itself.
On 18 November 2025 the central bank liquidated Banco Master and three related companies. It placed a fourth, Banco Master Múltiplo, under a temporary special administration to preserve its digital bank.
Master’s controlling shareholder Daniel Vorcaro was arrested in São Paulo the same day. The deposit guarantee fund paid out about 41 billion reais to some 1.6 million creditors, its largest ever.
What BRB Was Left Holding
The core of the problem is about 12.2 billion reais of credit portfolios BRB had bought from Master. The bank says roughly 10 billion of that was substituted with other assets.
It is the quality of those substitutes that drives the loss estimate. They include property linked to the Vorcaro family, non-performing loans and illiquid fund holdings.
The central bank required 2.6 billion reais of provisioning in January 2026. Ailton de Aquino, its director of supervision, told federal police in December that the eventual figure could approach 5 billion reais.
That testimony became public in January. He described the extra 2.2 billion as reflecting the low quality of what Master handed over.
The Fund That Never Happened
In April 2026 BRB announced a plan with the manager Quadra Capital. About 15 billion reais of Master-origin assets would move into a fund, with 3 to 4 billion in cash up front.
The talks ended on 17 July 2026 over disagreements about the economic terms. BRB said no cash had been transferred and that it would manage and re-place the assets itself.
The Court Order Was BRB’s Own Doing
In February 2026 a civil court in the Federal District froze shareholdings worth about 376.4 million reais. It is easy to read that as an action against the bank’s circle.
It was the opposite. BRB itself asked for the injunction, to secure assets against losses it expects to recover later.
The shares frozen are holdings in BRB’s own capital, held by the defendants and by a group of investment funds. The case is under seal, so the identities reported in the Brazilian press cannot be verified from the file.
Where the Bank Stands Now
Nobody outside can say what BRB’s capital position is, because it has published nothing for over a year. The bank says it remains solid with adequate liquidity.
It proposed a capital increase of up to 8.86 billion reais in March 2026. It was still seeking the money in late August.
Its own leadership privately puts the hole at about 8.8 billion.
The central bank has not imposed any special regime on BRB. A recovery plan submitted in February carried a 180-day deadline that passed on 5 August with the measures unimplemented.
The People and the Politics
Former chief executive Paulo Henrique Costa was dismissed in November 2025 and arrested in April 2026. Nelson Antônio de Souza, once head of Caixa, now runs the bank.
Governor Celina Leão suspended staff who approved the Master deals and removed twelve directors in April. A shareholders’ meeting approved legal action against a former administrator on 24 August.
The rescue on the table is a 6.6 billion reais loan from the deposit guarantee fund to the Federal District government. It was agreed through a Supreme Court conciliation in May and has not closed.
Banco do Brasil declined to lead the lending consortium and asked to be excused from a hearing in August. On 1 September the finance ministry refused the governor a meeting, saying structuring the deal is not the federal government’s job.
