Ueno Bank collapse exposes governance fracture threatening Paraguay's credit rating.

The collapse of Ueno Bank has exposed an institutional fracture of proportions Paraguay has not confronted in decades, and the speed with which the case has escalated — from a bank failure to a governance crisis threatening the country's sovereign rating — is what sets this week apart from any other in the recent economic cycle.

The Banco Central del Paraguay has initiated a "resolution procedure" against Ueno Bank after uncovering a web of loans concentrated in companies linked to its own directors, leading to the detention of at least 27 individuals charged, including executives and shareholders. The assets of the directors and shareholder companies have been subject to judicial seizure, while the Superintendencia de Inversiones (SIV) has suspended public offerings and trading of all securities issued by the entity. The magnitude of the financial hole is still not known with precision, and that opacity is, according to multiple economists cited by ABC Color, the principal risk factor: expanding the Deposit Guarantee Fund without knowing the real size of the losses could commit system resources on a scale impossible to calculate.

What makes this episode qualitatively different from an ordinary bank failure is the scale of public exposure. The Instituto de Previsión Social (IPS), the country's largest pension fund, had approximately USD 355 million deposited at Ueno — a figure that climbed from barely USD 20 million in a relatively short period, according to Última Hora — raising questions of institutional accountability that have already reached Congress. In addition, the Administración Nacional de Electricidad (ANDE) itself had funds trapped in the entity, both from its works fund and from its Pensioners' Fund. The Cámara de Comercio questioned the use of the Guarantee Fund to cover public deposits rather than prioritizing private savers — a position shared by the Asociación Rural del Paraguay (ARP), the Asociación de Empresas del Comercio (Adec) and the Federación de Cooperativas de Producción (Fecoprod).

The BCP responded with a sequence of emergency measures: it appointed Liana Caballero as interim president following the resignation of Carlos Carvallo, who departed amid the storm alongside director Carmen Marín. President Santiago Peña announced changes in the agency's leadership and nominated Raúl Vera Bogado as candidate for the permanent presidency. The central bank also released the aliases registered at Ueno so that depositors could reuse them at other institutions, the IPS began reassigning retirees to other banks, and the Executive promulgated an emergency law to accelerate the return of deposits in the shortest possible time. The Senate had previously passed legislation enabling advance payments within 24 hours, although details regarding timelines, tranches and maximum amounts remain subject to public clarification by the BCP.

The reaction of the business sector was immediate and broadly unanimous in its general lines, though divergent on the details. AmCham warned of the impact on the business climate and legal certainty, demanding that the independence of the judicial process be preserved and political pressures avoided. The Unión Industrial Paraguaya (UIP) demanded full transparency. The soy industry warned of negative effects on investment. The multi-store retail guild spoke directly of a "semi-paralysis" of the market. Capex reported that several exporting companies are already reducing operations due to exchange-rate uncertainty. The guaraní, which had appreciated nearly 36% against the dollar in two years and whose strength had been celebrated as a sign of macroeconomic stability, has become a problem: the drop in the exchange rate has already eliminated some 3,000 jobs in the maquila sector and compressed agricultural revenues. Exporter guilds formed a technical roundtable with the Ministerio de Economía to seek solutions, while economists consulted by La Nación called for BCP intervention during episodes of extreme volatility.

That Ministerio de Economía is, in itself, an institutional novelty. Created during the Santiago Peña administration by merging the Ministerio de Hacienda, the Secretaría de la Función Pública and the Secretaría Técnica de Planificación, it welcomed its new head this week, Óscar Lovera, who was sworn in with the presidential instruction to maintain social programs while managing what the government itself calls a "war economy": a fiscal adjustment driven by an abrupt drop in revenue collection that the MEF expects to correct by 2028. Lovera, who participated in World Bank and IMF meetings on the country's behalf, has already announced the payment of USD 80 million in debts to pharmaceutical companies as a first signal of management. The Dirección Nacional de Ingresos Tributarios, which merged the SET and the Dirección de Aduanas, aims to raise the tax burden from 10% to 12% of GDP and collect an additional USD 400 million per year.

The macroeconomic backdrop remains robust in its fundamentals, which makes the contrast all the more striking. The BCP reported cumulative GDP expansion of 5.7% through August, the IMF projects that Paraguay will grow at nearly double the global average, and non-agricultural labor informality fell to 56.8% according to the INE. Itaipú transfers to the State, however, fell by USD 18 million year-on-year, adding pressure to the fiscal picture. The Bolsa de Valores recorded record trading levels, although partly explained by the exchange-rate effect on guaraní-denominated valuations.

The central question for the coming weeks is whether the Ueno case will have an impact on the country's sovereign rating. The Asociación de Bancos (Asoban) insisted that the financial system as a whole remains solid and that the episode should not affect the investment grade, a position backed in formal statements by Banco Atlas, Sudameris and Banco Familiar. Other analysts, cited by ABC Color, disagreed: they questioned the BCP's belated reaction, the design of the supervisory mechanism that allowed risk accumulation at Ueno, and warned that the crisis has already echoed in international media, which will inevitably attract investor scrutiny. The appointment of the new BCP president and the transparency of the liquidation process will be the variables to monitor with greatest urgency.
