Arrest of Former Bolivian President Luis Arce Sparks Debate Over Accountability and Political Future
A Defining Moment for Bolivia’s Political System
The arrest of former Bolivian president Luis Arce has become more than a judicial event; it has evolved into a defining moment for Bolivia’s political system. Across the country, the case has reignited debates over corruption, selective justice, and the legacy of the Movement for Socialism (MAS), a party that dominated Bolivian politics for nearly two decades. According to experts surveyed by the Social Research Center, the arrest reflects a convergence of accumulated economic failures, political fragmentation, and a shifting balance of power within the state.
For supporters of the move, the detention represents long-delayed accountability. For critics, it raises familiar concerns about politicized justice and the use of courts as instruments of power. What is clear, however, is that Arce’s arrest has reopened unresolved questions about governance, institutional credibility, and the sustainability of Bolivia’s political model after the erosion of MAS’s dominance.

Economic Collapse and Political Fragmentation
For many analysts, the foundations of the current crisis lie in Arce’s economic record and the political consequences that followed. Oscar Mario Tomianovic Parada, a Bolivian political scientist and economic analyst, offered a stark assessment of the former president’s tenure. “Luis Arce’s economic administration can be summarized as follows: a collapse in economic activity (-2.4% in the first half of 2025) and accumulated inflation above 20%, placing the country technically in a recession. The exchange-rate gap exceeded 150%, while International Reserves stand at barely USD 75 million—compared with more than USD 13 billion recorded in 2014–2015. Fiscal deficit remains a persistent issue, with more than a decade of consecutive imbalances averaging over 8% of GDP,” he explained.
These figures, experts argue, highlight not only policy failure but also the exhaustion of the economic framework inherited from the MAS era. Rising inflation, declining reserves, and persistent fiscal deficits gradually eroded public confidence, weakening Arce’s political authority and narrowing his room for maneuver.
Beyond macroeconomic deterioration, Tomianovic Parada emphasized the political consequences of Arce’s leadership. He noted that Arce ultimately triggered the fragmentation and fall of MAS, transforming it from a dominant force in the Legislative Assembly into a marginal actor with just 2 out of 130 representatives and no senators—an unprecedented collapse in Bolivia’s recent political history. This fragmentation left the former president increasingly isolated, both within his party and across the broader political spectrum.
Why Now? Judicial Action and Political Timing
While the allegations surrounding Arce have circulated for years, experts agree that the timing of his arrest is closely tied to changes in political protection and institutional incentives. Tomianovic Parada stressed that the accusations themselves are neither new nor unexpected. “The accusations against Arce are serious, yet widely known among the Bolivian public. Corruption linked to the Indigenous Fund remains an unresolved matter, and the expectation is that the new government will clarify the former president’s involvement,” he said. He also underscored the legal context of the case, noting that “Arce faces ordinary judicial proceedings, as the alleged irregularities occurred while he was still serving as Minister of Economy.”
From this perspective, Arce’s loss of office marked a decisive turning point. Without presidential immunity or a cohesive party apparatus to shield him, long-standing cases that once appeared politically untouchable moved forward with renewed momentum.
David Duran Ibañez, a political analyst and consultant, placed even greater emphasis on the political calculus behind the arrest. “From a pragmatic political perspective, this is an act of retaliation. They seek to quickly apply whatever legal criteria can justify his detention… Politically, this benefits Rodrigo in the current context and grants him legitimacy,” he argued. Duran Ibañez also highlighted the central role of public opinion, observing that “the public largely wants to see him imprisoned; going against that sentiment would carry a negative political cost.”
An Institutional Crisis Beyond One Individual
Several experts warned that focusing solely on Arce risks overlooking deeper institutional weaknesses. Camila Patzi Valenzuela, a political scientist specializing in public opinion and democratic institutions, described the arrest as symptomatic of a broader crisis. “His administration failed to consolidate trust, and this arrest is a reflection of long-standing institutional weaknesses,” she said.
According to Patzi Valenzuela, the case underscores how unresolved governance failures accumulate over time, eventually surfacing in moments of political rupture. Looking ahead, she stressed that Arce’s prospects are limited on multiple fronts. “Judicially, the outcome will depend on the progress of the case and the sanctions that may be imposed as the investigation advances. Politically, his ability to regain leadership within MAS appears significantly weakened, making it unlikely for him to return to public office or lead a political organization.”
From an external vantage point, Carlos Salas, an analyst based in Mexico, highlighted the symbolic nature of the arrest within a fractured political environment. “Because he has lost the protection of office, MAS is fractured, and the new government needs a quick symbol of ‘fighting corruption,’” he said. However, Salas cautioned that symbolism cuts both ways, warning that “in such a politicized judicial system, there’s a risk it will be seen merely as the current government’s ‘witch hunt.’”
The End of an Era — or the Start of Selective Justice?
For Lily Penaranda, a Bolivian political scientist and foreign policy analyst, the arrest marks a turning point in Bolivia’s political narrative. “MAS shifts from being a hegemonic force to becoming the target of review and punishment. This is not just a judicial case—it’s a political message to the entire ‘Evista–Arcista’ sphere: the era of impunity is over, at least according to the official narrative,” she explained.
Yet Penaranda also warned that the long-term impact will depend on how far accountability extends. “The case could open a Pandora’s box: if only Arce is investigated, it reinforces the perception of selective justice; if the investigation reaches other levels of MAS and its allies, it could shake much of the political elite.” In this sense, the arrest could either mark the beginning of institutional renewal or deepen cynicism toward the justice system.
Conclusion: A Test of Credibility for Bolivia’s Democracy
While the arrest has not yet triggered immediate economic disruption or institutional paralysis, experts agree that it has deepened political polarization and placed Bolivia’s justice system under unprecedented scrutiny. As analysts surveyed by the social research center consistently emphasized, the outcome will not be judged solely in courtrooms, but in public perception and political memory.
In the words of Lily Penaranda, this moment signals that “MAS shifts from being a hegemonic force to becoming the target of review and punishment.” Whether this represents a genuine break with impunity—or simply a change in who controls the levers of justice—may ultimately define the next chapter of Bolivia’s democratic trajectory.
