Bolsonaro Found Guilty: How Brazil’s Crisis Fuels Populist Winds in US-Brazil Relations
By Dr Christopher Sabatini, Senior Research Fellow for Latin America, US and the Americas Programme

Supreme Court Ruling Deepens Brazil’s Political Crisis
In a landmark but contentious decision, a five-member panel of Brazil’s Supreme Court found former President Jair Bolsonaro guilty of conspiracy to overturn the country’s 2022 election result. The sentence—reportedly up to 27 years—marks the most significant reckoning for a political leader in Brazil since the end of military rule in 1985. The decision was not unanimous: Justice Luiz Fux, appointed by incumbent President Luiz Inácio Lula da Silva, dissented, exposing deep divisions not just within the political landscape but also within key institutions.
Bolsonaro, a populist ex-army captain, was joined in the verdict by seven former and current military advisors. All were found complicit in orchestrating the 8 January 2023 insurrection, when crowds, stirred by claims of a stolen election, stormed government buildings in Brasília. The incident sent shockwaves through Brazilian democracy and invited global comparisons to the January 6, 2021, insurrection at the US Capitol.
Polarization and Populist Solidarity
Bolsonaro has consistently claimed that Brazil’s electronic voting system was prone to fraud, despite an independent audit in 2022 confirming its integrity and transparency. His rhetoric resonated strongly with a hardcore political base, often referred to as the ‘bible, beef, and bullets’ coalition—evangelical Christians, rural agribusiness sectors, and gun-rights advocates. Many analysts observe striking parallels to Donald Trump’s enduring appeal among US populists, with both leaders relying on similar messages of anti-institutional grievance and opposition to so-called “woke” agendas.
The Supreme Court’s non-unanimous verdict has only deepened divisions. Bolsonaro’s loyalists, already galvanized by years of battles over press freedom and judicial intervention, see the legal process as politically motivated. At massive rallies across Brazil on Independence Day, September 7, 2025, tens of thousands not only rallied for Bolsonaro but also brandished US flags and called directly for President Trump’s intervention—a reflection of how deeply Brazil’s right-wing populism has become entwined with American political trends.
US Intervention and Diplomatic Fallout
The political aftershocks have not been limited to Brazil. The US under President Donald Trump has intervened aggressively in support of Bolsonaro. Trump vocally decried the court’s actions as a ‘witch hunt’ and, in July 2025, imposed 50% tariffs on most Brazilian exports to the US. While carveouts spared significant sectors such as orange juice, aircraft, and minerals, these measures targeted key segments of Brazil’s economy. However, the US constitutes just 12% of Brazil’s export market, compared with a dominant 28% to China, highlighting the limited though symbolically potent nature of these tariffs.
The Trump administration’s actions did not stop with trade. It invoked the Global Magnitsky Act to sanction Supreme Court Justice Alexandre de Moraes and his colleagues, freezing their US assets and cancelling their visas. Moraes, now at the centre of the storm, previously drew the ire of both Bolsonaro and Trump supporters for leading a crackdown on online disinformation and demanding platforms like Twitter/X and Rumble remove accounts spreading electoral conspiracy theories. Elon Musk’s initial resistance was broken by daily fines totaling nearly $900,000, making Brazil a significant international battleground for platform regulation and free speech controversies in 2024–2025.
Trump’s moves drew criticism from pro-business and conservative voices within Brazil, with some warning that such interventions risked strengthening Lula’s position ahead of the 2026 presidential elections. The broad public perception, both domestically and abroad, is of rising US interference in Brazilian internal affairs under the guise of defending ‘freedom of expression’ and populist allies.
Global Implications: Populism, Democracy, and Precedent
The conviction of Bolsonaro, prohibited from holding office until at least 2030 due to earlier efforts to undermine the electoral system, leaves the country at an impasse. Despite legal roadblocks, his Liberal Party remains one of Brazil’s most influential political forces, with many observers predicting continued heavy pressure on the judiciary, especially if the party expands its congressional share in the 2026 elections. Behind the courtroom drama lies a broader existential struggle: whether Brazilian democracy can weather trends of grievance-driven populism and anti-institutional activism familiar across the United States, Europe, and parts of Asia.
Internationally, Brazil’s crisis has become a cautionary tale. The Trump administration’s readiness to use both public diplomacy and private business leverage—including lawsuits by the Trump Media & Technology Group against Moraes in US courts—signals a new, assertive phase in how populist leaders coordinate across borders. The latest actions from Washington have raised alarms among multilateral organizations and Latin American governments concerned about American precedent in undermining independent judiciaries. The region’s history—marked by military coups and transitions—shadows current events, with justice and accountability debates echoing from Argentina and Guatemala to Brazil.
The Road Ahead
For now, Bolsonaro and his co-defendants have vowed to appeal the verdict to the full 11-member Supreme Court, a move that could delay resolution for months. Meanwhile, Lula and his party must navigate a turbulent landscape where public trust in institutions remains volatile. International markets have reacted with caution, watching how sanctions, tariffs, and political unrest may ripple outward from South America’s largest economy.
Yet for all the turbulence, Bolsonaro’s core supporters remain fiercely mobilized, predicting his transformation into a martyr figure—a symbol for ongoing resistance to what they see as elite overreach. Political observers warn that, even with legal barriers, the populist brand Bolsonaro inaugurated is poised to persist, not only in Brazil but as part of a global trend challenging established Western democratic norms.
The current moment offers no easy resolution. With the 2026 presidential election looming and no immediate end in sight to judicial infighting and international tensions, Brazil’s ordeal encapsulates larger questions about democracy’s resilience, external influence, and the durability of populist movements in a globally connected era.
