The political and economic dynamics of the Latin American region were once again rocked by a seismic shock in early November 2026. The financial crisis triggered by the collapse of Ueno Bank Paraguay’s largest digital banking institution, holding the savings of nearly three million customers, or more than half the country’s adult population, rapidly escalated into an existential crisis for the country’s governance (Al Jazeera, 2026). The culmination of this upheaval was the impeachment of President Santiago Peña by the Paraguayan Senate, following a vote with an absolute majority of 44 to 1 on 6 November 2026, which was followed by the inauguration of Vice-President Pedro Alliana as the country’s 53rd head of state. The ousting of this former International Monetary Fund (IMF) economist not only highlights the fragility of domestic accountability but also presents an intellectual puzzle in the field of international relations: how the penetration of digital financialization and technocratic regulatory negligence can undermine a country’s political stability and trigger a potential geopolitical reorientation in the Southern Cone region.
The downfall of Santiago Peña marks an important precedent in Latin American political economy, in which a leader with a highly technocratic mindset found himself ensnared in a web of private financial conflicts of interest. An official investigation revealed that Ueno Bank had absorbed more than USD 800 million in public funds, including USD 355 million in pension funds from the Social Security Institute (IPS), before its solvency ratio plummeted below the minimum threshold of 50 per cent due to high-risk lending practices to affiliated entities (Bisnis, 2026). Congress’s rejection of Peña’s letter of resignation and its decision to proceed with formal impeachment proceedings were aimed at lifting his legal immunity to facilitate an investigation into the alleged conflict of interest. From an international relations perspective, this phenomenon transcends the scope of ordinary banking issues; the Asunción crisis is a distorted reflection of the fragility of a ‘small state’ structure that is unevenly integrated into the currents of global financial capitalism.
Casino Capitalism and State Capture
From the perspective of international political economy, the Paraguayan financial crisis can be analyzed using the framework of ‘casino capitalism’ proposed by Susan Strange. Strange (1986) argues that the dominance of deregulated financial markets often disregards the basic functions of the real economy and transforms the banking system into an arena for high-risk speculation that erodes state capacity. In Paraguay, the transformation of Ueno Bank from 2021 onwards into the country’s fifth-largest commercial bank illustrates a phenomenon of ‘fintech statecraft’ that is not counterbalanced by independent prudential supervision. When regulatory bodies such as the Central Bank of Paraguay are co-opted by political patronage networks between executive officials and the private business elite, the state effectively suffers from a paralysis of financial control.

The implications of this regulatory paralysis are devastating for the credibility of sovereign debt and the state’s financial reputation in the eyes of international actors (Hellman et al., 2003). The phenomenon of public funds being channelled into high-risk banking entities reflects a fundamental contradiction within neoliberal technocracy: the narrative of digital efficiency and financial inclusion is, in fact, exploited to facilitate capital accumulation by domestic oligarchic factions. When international credit rating agencies and foreign investors assess Paraguay’s sovereign risk, the collapse of Ueno Bank not only downgrades the country’s debt rating but also increases the cost of international borrowing for national development. Thus, the domestic banking crisis directly transforms the structure of Paraguay’s economic vulnerability within the global financial governance framework.
Non-Traditional Security Threats and Domestic Institutional Fragility
In addition to the political-economic dimension, the impeachment of President Peña must be viewed through the lens of human security as part of the study of non-traditional security (NTS). As formulated by the United Nations Development Programme and expanded upon by security experts, human security encompasses not only protection from military threats but also the guarantee of economic security and personal security (Paris, 2001). The sudden freezing of access to the savings of three million and the embezzlement of public pension funds triggered massive economic deprivation and profound social unrest across the country. The state’s inability to protect its citizens’ basic assets created structural vulnerabilities that could trigger prolonged political instability and waves of transnational economic migration. Simultaneously, this crisis laid bare the political implosion within the Colorado Party (Asociación Nacional Republicana), which had dominated the Paraguayan political scene since the 20th century (Mainwaring & Scully, 1995). The breakdown in relations between Santiago Peña and former President Horacio Cartes, leader of the Honor Colorado faction, demonstrates just how vulnerable the institutional structures of political parties in small states are to factional strife when crises over the distribution of resources arise. The decision by the Cartes faction to support Peña’s impeachment demonstrates that the political elite are prepared to sacrifice the head of state in order to safeguard the party’s institutional legitimacy in the eyes of the public. However, this domestic fragility has far-reaching and crucial implications for the stance and consistency of Paraguay’s foreign policy.
Geopolitical View: The Taiwan-China Diplomatic Dilemma and Regional Dynamics
The most unforeseen and strategic impact of President Santiago Peña’s impeachment lies in the potential shift in the geopolitical landscape of Latin America. Paraguay currently holds a unique position as the only country in South America that still maintains official diplomatic relations with Taiwan (Taylor, 2021). Under Peña’s leadership, Asunción consistently voiced support for Taiwan at international forums in exchange for development aid and technical investment from Taipei. However, the financial crisis triggered by the Ueno Bank scandal has placed President Pedro Alliana’s new administration in a dire fiscal position, with the country requiring an immediate boost to liquidity and large-scale infrastructure investment. This economic emergency created a geopolitical opening for the People’s Republic of China (PRC) to pursue economic diplomacy (i.e., geoeconomic leverage) more aggressively (Ellis, 2021). China, which is the main buyer of Latin American soya and beef, has long utilized massive credit allocations and market access to persuade Taiwan’s allies in the region to shift their diplomatic recognition to Beijing. If President Pedro Alliana fails to stabilize the banking system and attract external investment from his traditional allies, pressure from Paraguay’s domestic agribusiness sector to establish direct trade relations with Beijing will become increasingly unstoppable. A shift in Paraguay’s diplomatic recognition from Taipei to Beijing would not only bring down the last bastion of Taiwan’s diplomacy in South America but also mark a significant geopolitical victory for Beijing in eroding the strategic influence of the United States in the Western Hemisphere.
Furthermore, the dynamics of the crisis in Asunción have a direct impact on the performance of regional economic integration within Mercosur (Mercado Común del Sur). As a founding member of Mercosur alongside Brazil, Argentina, and Uruguay, Paraguay’s political instability disrupts the continuity of high-level negotiations, including the finalization of the Mercosur–European Union (Malamud, 2019). The leadership deadlock in Asunción has created a period of uncertainty regarding the harmonization of tariff regulations and regional climate commitments, which ultimately weakens Latin America’s geo-economic bargaining position in the face of great power competition.
The Ueno Bank scandal and the impeachment of President Santiago Peña demonstrated that, in an era of global digital financialization, domestic financial instability in a developing country can rapidly transform into a crisis of political sovereignty and act as a catalyst for regional geopolitical reorientation (Strange, 1996). Technocratic regulatory negligence and the co-optation by the oligarchy not only undermine human security at the local level but also weaken the state’s diplomatic bargaining position on the international stage. For the government of President Pedro Alliana, the pressing challenge is to carry out a transparent reconstruction of the banking institutions while navigating the geopolitical dilemma between Taiwan and China with precision (Long, 2017). Failure to manage this crisis will accelerate the shift in the balance of power in South America, strengthen Beijing’s geo-economic penetration, and confirm that state sovereignty in the 21st century is heavily dependent on the resilience of the domestic financial system against the tide of global financialisation.
