A recent decision by Brazilian Supreme Court Justice Flávio Dino directly challenges the effectiveness of the US Magnitsky Act within Brazil, sparking a serious legal and diplomatic dispute. The ruling, issued last Monday from São Luís, while not explicitly naming the Magnitsky Act, was clear in its intent and has been described as a 'bomb' in financial circles. It places Brazilian banks in a dilemma: either comply with US sanctions (imposed on fellow STF Justice Alexandre de Moraes) or adhere to Dino's ruling, which asserts Brazilian sovereignty.

Dino's decision states that laws from another country will not be effective in Brazil when they offend national sovereignty, and that foreign decisions can only be executed in the country upon homologation. The financial sector has described this situation as "grave" and "unfulfillable," as compliance with the US Treasury's OFAC is considered imperative for banks' survival in the global financial market. The US State Department, for its part, stated that "no foreign court can invalidate US sanctions," signaling a potential escalation in tensions.

This conflict is not merely a legal challenge but a strategic dilemma for Brazilian companies and financial institutions that conduct business with the US or handle dollar-denominated transactions. Dino's ruling provided 'backup' for Justice Moraes, who is already facing financial restrictions. The ball is now in the Brazilian banks' court, who are expected to seek clarification from Dino regarding the scope of his decision or may resort to US courts.

Market Signals

Brazilian banks are on urgent alert, reviewing contracts and compliance policies for fear of secondary sanctions from OFAC, which could include fines, asset freezes, or loss of access to the US banking system.
Banks consider OFAC compliance more critical for their survival in the global financial market than the Brazilian Supreme Court's decision, creating an "unfulfillable" dilemma.
This situation may limit dollar transactions, international credit card use, and investments tied to US assets.

Winners & Losers

Winners: Legal and consulting sectors (due to increased demand for specialized services in international law and compliance). Political figures critical of Moraes and the Brazilian Supreme Court.

Losers: Brazilian financial institutions (exposed to secondary sanctions, volatile regulatory environment). International investors (may perceive increased country risk and legal instability in Brazil). Brazilian Supreme Court justices (fear of becoming targets of future sanctions).

Action Timeline

Immediate: Banks are expected to seek clarification from Justice Dino and conduct urgent risk and compliance analyses.
Short-term: Evaluating strategies for diversifying banking relationships and closely monitoring regulatory developments. A bill to render the Magnitsky Act ineffective in Brazil is under discussion.
Long-term: Potential re-evaluation of the operating structure of Brazilian financial institutions in international transactions and implications for Brazil's standing in international legal disputes.

Risk Assessment

Regulatory Risks: Risk of secondary sanctions from OFAC and conflict between national and international laws.
Market Volatility Factors: Uncertainty leading to fluctuations in exchange rates, capital markets, and investment flows.
Geopolitical Tensions: Escalation of tensions between Brazil and the US could worsen the situation, impacting trade and diplomatic relations.

The issue highlights the dilemma of national sovereignty versus global financial compliance, making it a focal point in Brazil-US relations.
