Paraguay’s central bank has taken control of Ueno Bank after the lender’s capital ratio fell far below the legal threshold, suspending its services and leaving customers unable to access their accounts. The intervention puts savings and substantial public funds under review, while prompting investigations and renewed scrutiny of political ties to the bank.
The takeover is a resolution process, not an ordinary court bankruptcy: regulators say they will assess the bank, protect assets and seek to transfer deposits. The case highlights how fast-growing digital banking can test supervisory safeguards and depositor protections.
Why regulators intervened
The central bank’s board voted unanimously to place Ueno into resolution after its solvency ratio fell below half the legal minimum. Regulators said the process would put officials in charge of the lender, determine its financial position and protect assets. The central bank described the difficulties as confined to Ueno, rather than a threat to the banking system as a whole.
Central bank chief Carlos Carvallo said regulators had raised concerns about loans to companies linked to the bank’s owners, then found more serious irregularities during a deeper review. Authorities plan to investigate responsibility for the deterioration and consider sanctions. Prosecutors ordered the arrest of eight people, including Ueno’s president and chief executive; two additional directors were later taken into custody, according to prosecutors.
What depositors face
Customers reported being locked out of Ueno’s app, and the bank’s services—including cards—were suspended. By law, insured deposits are to be paid within 15 days of the takeover, with a possible extension of another 15 days. The central bank said an initial payment of up to 10 million guaraníes per customer would be made, but did not give a date. Depositors with balances above the insurance cap have no guarantee of full repayment; their recovery will depend on the resolution and any liquidation.
According to GlobalData’s 2026 Consumer Survey, 86.7% of consumers across six other Latin American markets use digital banking at least monthly, and 38.1% now prefer to use a banking app for everyday tasks, the highest share of any surveyed region.
What about public funds
The exposure of Paraguay’s state pensions, with about $355 million invested in the bank, compounds the problem by tying public finances to private governance.
“This collapse also tests the limits for deposit protection; guarantee schemes were designed to absorb the failure of smaller institutions, not a lender serving the majority of the population. Any move to try and stretch the fund to cover public money risks reducing the resources that protect ordinary savers in the event of future failures. Concerns around the independence of supervisors, given the central bank governor’s role at the bank’s predecessor, further weaken the confidence at a time when it is needed most”.
The state pension and health fund said pension payments would continue as usual and that it would move about 32,000 retirees who receive payments through Ueno to another bank. The fund also said it would pursue legal action to recover its investment.
Political and market fallout
President Santiago Peña canceled a planned trip abroad, called for Carvallo’s resignation and said his administration would seek legislation to speed depositor payouts and guarantee the return of public money. Carvallo said he had signed his resignation but would remain temporarily to oversee the process.
The intervention has intensified questions about oversight and potential conflicts. Carvallo led Ueno’s predecessor before Peña appointed him to head the central bank, while Peña remained a business partner of Ueno’s parent conglomerate until 2025. Both Peña and the bank have denied wrongdoing, and the central bank has said Carvallo recused himself from decisions involving Ueno. Opposition lawmakers are calling for impeachment proceedings, while the bank’s failure challenges Paraguay’s efforts to attract investment through a reputation for stability.
The problem was not technology
“The failure is particularly significant as the apparent causes behind it seem to have very little to do with technology”, observes Rhys Hicks, Associate Banking and Payments Analyst at GlobalData. Investigators are looking into $146 million in lending linked to the bank’s controlling group. This appears to be a governance failure delivered from a newer digital platform. Digital banking massively lowers the costs of new customer acquisitions and cuts the time for sign up, allowing lenders to accumulate deposits much quicker than their risk controls and capital base can mature. Supervisors typically judge a bank’s systemic importance by the size of its balance sheet, but Ueno’s collapse shows that customer reach should also be an important factor. When an estimated 60% of a country’s adults rely on a single institution for its payments and savings, its failure becomes a huge public confidence event, regardless of asset size”.
