Rio State Overstated Books by $225m on Failed Banco Master
BRAZIL · POLITICS
Key Facts
—The ruling. Rio de Janeiro’s state audit court rejected former Governor Cláudio Castro’s 2025 accounts by a 3-1 vote on June 1.
—The core issue. Auditors found a R$1.13bn ($225m) overstatement of state assets, from a failure to provision for losses on the state pension fund’s exposure to Banco Master.
—The scale. Federal police put the state pension fund’s total Master-linked investments at about R$3.7bn ($736m); an extraordinary audit was ordered on roughly R$5bn ($994m) across several institutions.
—Next step. The opinion is advisory; the state legislature has the final say on whether to approve or reject the accounts.
—The backdrop. Castro, already ruled ineligible by the electoral court in March, called the decision contrary to earlier favourable technical opinions.
The collapse of Banco Master is now reaching the books of a Brazilian state government, after Rio’s auditors found the failed bank’s losses left a billion-real hole in the accounts that funds public-servant pensions.
Auditors find “widespread distortions”
The Rio de Janeiro State Audit Court rejected the 2025 accounts of former Governor Cláudio Castro by three votes to one on Monday. The rapporteur, councillor José Gomes Graciosa, cited “widespread distortions in the presentation of values” in the state’s financial statements, including an artificial overvaluation of assets. He also flagged a R$823m ($164m) gap between the cash position reported in the state’s fiscal statements and the balances confirmed by banks, along with breaches of fiscal targets and irregularities in opening supplementary budget credits.
Castro said the ruling contradicted earlier favourable opinions from the court’s own technical staff and the public prosecutor’s office, and said he regretted the decision.
How Banco Master pulled down the balance sheet
At the centre of the rejection is Rioprevidência, the state pension fund, which held investments tied to Banco Master. Auditors said the state failed to set aside provisions for possible losses on those assets, inflating reported net worth by R$1.13bn ($225m). According to the federal police, the Rio government’s Master-linked investments channelled through Rioprevidência reached about R$3.7bn ($736m) over Castro’s administration. The court ordered an extraordinary audit of roughly R$5bn ($994m) the state placed across financial institutions, including Master, the South Korean group Mirae Asset (about R$2.6bn, or $517m) and Banco Genial (about R$1.7bn, or $338m).
Banco Master was wound down at the end of 2025, and its controlling shareholder remains in custody amid investigations into large-scale financial irregularities. Because the exposure sits inside the pension fund, the shortfall touches the retirement savings of Rio state public servants.
What happens next
The audit court’s verdict is advisory. The opinion now goes to the Rio de Janeiro state legislature, which holds the final vote on whether to approve or reject the accounts and may follow or set aside the recommendation — leaving the outcome politically uncertain. Castro, who was ruled ineligible by the superior electoral court in March and subsequently dropped a planned Senate bid, faces the decision as the Master fallout continues to widen across Brazilian public finances.

A widening web around Banco Master
The Rio ruling is the latest strand of a scandal that has spread well beyond a single failed lender. The same collapse has driven an emergency rescue of the Brasília regional bank BRB and drawn scrutiny from federal auditors over public money parked in Master-linked vehicles. For investors and observers, the episode is a reminder of how exposure to one troubled institution can surface, with a lag, in the accounts of governments and state entities far from the original deal.
