Hacks & scams / Collapse

What happened

According to Reuters, Paraguay's central bank determined that Ueno Bank had breached minimum solvency requirements and placed it into resolution, with the board reportedly voting late on Monday, Nov. 2, and the move made public on Nov. 3, 2026.

According to AP-linked and other reports, the bank was seized, customer accounts were frozen, and officials planned to move viable accounts and assets to other banks before liquidating what remained. Reports say the app, cards, transfers and branch withdrawals stopped working, leaving depositors unable to access savings.

Reuters reported on Nov. 4 that roughly 3 million customers remained unable to access accounts and that executives were detained. Reuters, AP, BBC, UPI and NPR reported on Nov. 5 that President Santiago Peña resigned amid the banking crisis and impeachment pressure.

According to reporting cited in the research, the central bank chief reportedly resigned at the president's request as the crisis escalated, and protests and clashes with riot police were reported in Asunción.

How it worked

This appears to have been a bank solvency failure rather than a blockchain exploit or smart-contract failure. SBS reported the reserve requirement ratio fell to less than half the required standard, meaning emergency reserves held with the central bank were far below the level needed for normal operations.

AP reported investigators found loans to companies linked to the bank's owners, poorly documented lending, and expenses improperly counted as assets. These accounting and credit-quality problems, rather than a hack, are reported as the basis for the capital and liquidity failure that triggered seizure, account freezes and liquidation.

Timeline

• 2026-11-03Paraguay's central bank seized Ueno Bank and froze customer access to accounts, cards, app transfers and branches; reports say the central bank chief resigned at the president's request.
• 2026-11-04Reuters reported that about 3 million customers were still unable to access accounts and that executives were detained; lawmakers pressed impeachment efforts.
• 2026-11-05President Santiago Peña resigned amid the banking crisis and impeachment pressure, according to Reuters, AP, BBC, UPI and NPR.

Where the money went

No reporting in the research identifies on-chain fund flows, mixers, bridges or exchange destinations. Reports say viable accounts and remaining assets were to be transferred to other banks before liquidation; no frozen or recovered amount is confirmed. Reports say about 97 percent of depositors are preliminarily covered by deposit insurance up to 228.3 million guaranies per person per institution, though this figure is from a single secondary source and not independently verified.

The response

The central bank intervened, placed the bank into resolution and reportedly planned to transfer viable accounts to other banks before liquidation. Reports say the bank issued no immediate reassurance to customers. Some pension disbursements for about 32,000 retirees were reportedly routed through another institution. No official depositor compensation package was found in the reviewed coverage, though one report says an initial payout of up to 10 million guaranies per depositor was planned with no date given, and another says lawmakers passed a bill to speed partial payments.

Market and user impact

About 3 million customers, in a country of roughly 6.5 million people, reportedly lost access to accounts and cards, with one AP-linked report saying nearly half the population was left without bank account access. Protests were reported in Asunción, 13 mutual funds reportedly froze withdrawals, trading in Ueno bonds was reportedly suspended, and the head of state resigned. No verified market price series is available because Ueno does not appear to be a widely traded listed equity in the coverage reviewed.
