Paraguay's Central Bank took over Ueno Bank, the country's largest digital bank, with about 3 million customers. Its president resigned the same day. He chaired the bank's predecessor firm until 2023, and President Peña was a partner in its parent group until March 2025.
ASUNCIÓN — Paraguay’s Central Bank (BCP) announced early on Tuesday, November 3, 2026, that it has taken control of Ueno Bank, the country’s largest digital bank, after its solvency ratio fell below 50% of the legal minimum. According to the announcement, the BCP board voted unanimously on Monday night. The bank’s app, cards and transfers were suspended immediately.
The man who regulated the bank once ran it. The president who appointed him once owned a piece of the group behind it. Nobody in Asunción has explained who was watching the solvency numbers while the ratio fell by half.
Ueno has about 3 million customers, roughly 60% of Paraguay’s adult population. The BCP says it took over to assess the bank’s assets and liabilities and to protect depositors. Deposits of up to about $38,000 per person are covered by the country’s guarantee fund.
BCP President Carlos Carvallo resigned the same day. Carvallo chaired the former finance company that became Ueno until 2023, before President Santiago Peña named him to lead the central bank. Peña himself was a partner in the group that controls the bank until March 2025.
Arrests and frozen assets
Prosecutors ordered the detention of eight executives and people linked to the bank, including CEO Federico Miguel Vázquez and chairman Juan Manuel Gustale. The courts also froze the group’s assets.
Why it matters
Ueno managed hundreds of millions of dollars in public money, including about $380 million from the state pension fund, the IPS. That turns a banking failure into a question about retirees and public savings, not only private depositors. For American readers, the pattern is familiar from earlier bank crises: a supervisor and a supervised institution that share a past, and a collapse that arrives before anyone outside the circle has seen the numbers. The same fragility has run through recent coverage of a $133 million bank heist in France and the collapse of Turkey’s lira, and it now sits next door to Brazil, in the Mercosur trade bloc.
The record
Confirmed in the BCP announcement: the intervention, the unanimous board vote, the suspension of services and the resignation of its president. Ordered by prosecutors and reported: the eight detentions and the asset freeze. The BCP also states that the problem is isolated and poses no systemic risk to Paraguay’s financial system. That is the central bank’s own assessment, and the Watch Post Daily has not independently verified it.
What has not been established is how a bank slid below half the legal solvency minimum under a supervisor who once led it. No finding of wrongdoing has been made against Carvallo or Peña.
A regulator that resigns the day it seizes the institution it oversaw has answered one question and raised a larger one: how many other institutions in the region are supervised by people who know them from the inside, and who is checking their work.
