The United States’ decision to sanction Supreme Federal Court (STF) Minister Alexandre de Moraes under the Magnitsky Act, on Wednesday, July 30, 2025, in Washington, marked an escalation in diplomatic tensions between Brazil and the US. Announced by the Office of Foreign Assets Control (OFAC), the measure includes the revocation of visas for Moraes, his allies in the STF, and family members, as well as possible asset freezes. The justification, according to Secretary of State Marco Rubio, is linked to Moraes’ actions in the case against former President Jair Bolsonaro, who is a defendant for attempting a coup d’état after the 2022 elections. The sanction, which uses legislation created in 2012 to punish human rights violations and corruption, raises debates about Brazilian sovereignty and potential impacts on bilateral relations. Below are details about the case and its implications.
Origin of the Sanction and Political Context
The application of the Magnitsky Act against Alexandre de Moraes reflects a clash that transcends Brazilian borders. The legislation, approved in 2012 by the US Congress and expanded in 2016 for global reach, allows sanctions against individuals accused of corruption or serious human rights violations, such as torture, extrajudicial executions, or arbitrary arrests. In Moraes’ case, the American justification points to judicial decisions that, according to critics, curtail freedom of expression and persecute political opponents, especially allies of former President Jair Bolsonaro.
The sanction was formalized by OFAC, an agency of the US Department of the Treasury. The visa revocation covers Moraes, other STF ministers, and close family members. The measure is seen as a response to the STF’s investigations against Bolsonaro and his supporters. The articulation involved licensed Congressman Eduardo Bolsonaro, who seeks support in the US. There is internal resistance within OFAC, with fears that the measure could harm American credibility.
The case against Bolsonaro, reported by Moraes, investigates an alleged coup plot to annul the 2022 elections. The Attorney General’s Office (PGR) is also probing Eduardo Bolsonaro’s actions in the US, accused of inciting sanctions against Brazilian authorities, which heightens the complexity of the case.
Reactions in Brazil and Diplomatic Implications
The sanction generated a strong reaction in Brazil, with authorities classifying the measure as an affront to national sovereignty. The Brazilian government, through the Itamaraty (Ministry of Foreign Affairs), intensified contacts with the US State Department to avoid escalating the conflict. Representatives from the National Human Rights Council (CNDH) stated that the US action is an attempt at interference in internal affairs, emphasizing that the STF operates within the rules of the Democratic Rule of Law.
The Ministry of Foreign Affairs is considering the possibility of diplomatic retaliation, although it rules out reciprocal sanctions against American authorities. The absence of bilateral meetings between Presidents Lula and Trump, even at events like the G7 Summit, reflects the current tension. Analysts point out that the sanction could deepen the crisis in bilateral relations, especially in areas such as trade and military cooperation.
The Magnitsky Act and Its Practical Effects
The Magnitsky Act, created to punish Russian authorities after the death of lawyer Sergei Magnitsky, is now a tool with global reach. It allows the US government to impose sanctions such as asset freezes, bans on entry into the US, and blocking of financial transactions in dollars. For Moraes, the practical consequences include:
Asset freeze: Bank accounts and assets in US territory may be frozen. Travel restrictions: Visa revocation prevents entry into the US, also affecting family members. Global financial impact: International financial institutions may avoid transactions with sanctioned individuals. Commercial restrictions: Credit cards from American brands may be blocked. Symbolic effects: The sanction reinforces narratives of political persecution among opponents.
The application of the law requires reliable evidence of violations, such as suppression of fundamental freedoms or significant corruption. In Moraes’ case, US critics allege that his judicial decisions, such as blocking social media accounts, constitute transnational censorship.
Political Articulations and Transnational Clashes
The movement to sanction Moraes gained momentum with Eduardo Bolsonaro’s actions in the US. Since February 2025, the licensed congressman has been meeting with Republican lawmakers, such as Cory Mills, to pressure the Trump administration. A bill titled “No Censors on Our Territory,” approved by a US House committee, reinforces the narrative that STF decisions affect American citizens, although it does not directly name Moraes.
Moraes’ response to the American offensive, in February 2025, highlighted the independence of the Brazilian Judiciary and national sovereignty, evoking the date of September 7, 1822. The phrase, inspired by Guimarães Rosa, reinforced the STF’s tone of resistance. However, international pressure continues, with Bolsonaro’s allies using social media to amplify the discourse that Moraes is promoting a “witch hunt” against Bolsonarism.
Possible Developments and Future Tensions
The sanction against Moraes could set precedents for new measures against other STF ministers, as indicated by sources close to the Trump administration. Additionally, there is speculation about actions such as increased trade tariffs against Brazil or even technological sanctions, although such measures face internal resistance in the US. The US Department of the Treasury, for example, fears that applying the Magnitsky Act against a judge from an allied Supreme Court could compromise the US image as defenders of democracy.
In Brazil, the STF maintains its position of complying with due legal process, while the Lula government seeks to avoid a diplomatic crisis. The investigation against Eduardo Bolsonaro for obstruction of justice and coercion, authorized by Moraes, signals that the Brazilian Judiciary will not back down in the face of external pressures. The tension between the two countries, therefore, is expected to persist, with potential impacts on trade agreements and international cooperation.
International Repercussion and Criticisms
The American decision was widely covered by the global press. Newspapers like The New York Times and Financial Times highlighted the risk of a diplomatic rupture between Brazil and the US, the two largest nations in the Western Hemisphere. The British newspaper linked the sanction to an offensive against Moraes for his role in cases of disinformation and attempted coup. International analysts point out that the measure reflects a strategy by the Trump administration to confront institutions that do not align with its interests.
The Washington Post: Reported internal resistance in OFAC, with criticisms of the sanction for harming American credibility. The New York Times: Warned about the impact on bilateral relations, citing the clash with Elon Musk as a precedent. Financial Times: Emphasized Brazil’s diplomatic battle to avoid the sanctions. Human Rights First: Report indicates that 69 people were sanctioned under the Magnitsky Act in 2024. Legal experts: Question the legality of applying the law against a sitting judge.
The international community is watching closely, especially since it involves a judge from a supreme court, something unprecedented in recent international relations history.
Brazilian Sovereignty at Stake
The sanction against Moraes places Brazil in a delicate position. The Lula government, through its embassy in Washington, has reiterated that the STF’s decisions are legitimate and aim to protect democracy. Brazilian authorities, such as the Attorney General of the Union, Jorge Messias, stated that the Judiciary will not be intimidated by external pressures. The narrative of defending sovereignty has gained strength, with parliamentarians from different political spectrums condemning the American action as an attempt at interference.
Civil society is also reacting. The CNDH issued a note classifying the sanction as a violation of international norms, while movements in support of the STF are organizing demonstrations. On the other hand, sectors aligned with Bolsonarism celebrate the measure, seeing it as validation of their criticisms of the Brazilian Judiciary.
Paths to Resolving the Conflict
Resolving the crisis requires diplomatic delicacy. Brazil may opt for actions at the International Court of Justice (ICJ), questioning the legality of the sanctions, or intensify bilateral negotiations to reverse the measure. In the US, internal resistance in OFAC suggests that the full application of the Magnitsky Act, such as asset freezes, is not yet consensus. However, pressure from Bolsonaro’s allies keeps the issue prominent.
Diplomatic negotiation: The Itamaraty seeks dialogue with the State Department. International judicial action: Brazil is evaluating appealing to the ICJ against the sanctions. STF response: The court maintains its independence, without backing down in investigations. Internal pressure in the US: OFAC resists full application of the Magnitsky Act. Electoral impact: The sanction may influence the Brazilian political scenario in 2026.
The future of Brazil-US relations will depend on both sides’ ability to find a balance between political interests and respect for sovereignty. Meanwhile, the STF remains the protagonist in a clash that mixes justice, politics, and diplomacy on a global scale.
