Brazilian Markets Face Headwinds Amid Bolsonaro Trial and U.S. Tariff Dynamics

U.S. and Brazilian financial markets are navigating a period of heightened uncertainty, driven by the ongoing trial of former Brazilian President Jair Bolsonaro and the complex interplay of U.S. tariff policies initiated by former President Donald Trump. Investors are closely monitoring these developments, which have introduced significant volatility across Brazilian equities and currency markets.

Key Political and Trade Developments Unfold

The Supreme Federal Court (STF) in Brazil has commenced the final phase of Bolsonaro's coup trial, with proceedings expected to conclude by September 12. He faces charges of plotting to overturn the 2022 election results, potentially leading to over 40 years in prison and a ban from public office until 2030. This judicial process has amplified political polarization within Brazil and contributed to market jitters regarding policy continuity.

Simultaneously, U.S. trade policy has added a layer of complexity. Former U.S. President Donald Trump imposed a 50% tariff on Brazilian imports, citing "insidious attacks on Free Elections" and linking it to the Bolsonaro trial. This levy, initially set to affect a broad range of Brazilian goods, remains in effect until October 14. This tariff escalation followed a broader U.S. judicial ruling by the Court of International Trade (CIT) which struck down some of Trump's earlier "Liberation Day" tariffs as unlawful, though an appeal to the Supreme Court is underway. The initial tariff threats caused the Brazilian Real to slump nearly 3% against the U.S. dollar, and the iShares MSCI Brazil ETF (EWZ) to decline almost 2% in post-market trading.

Market Reaction and Economic Indicators

On Tuesday, Brazil's benchmark Ibovespa index registered a 0.67% decline, closing at 140,335 points, marking its second consecutive session of losses. This downturn occurred as the Supreme Court began deliberations on Bolsonaro's fate. The Brazilian Real depreciated 0.64% to 5.47 per dollar, reflecting increased political uncertainty. However, the EWZ showed a slight increase of 0.49% on a recent trading day, rising from $30.58 to $30.73, although with falling volume suggesting potential divergence.

The economic landscape in Brazil shows mixed signals. Second-quarter GDP expanded 0.4%, surpassing economist forecasts of 0.3% but sharply decelerating from the first quarter's 1.3% growth. This data prompted the Finance Ministry to signal a downward revision to its 2.5% annual growth target. Inflation pressures persist, with the Central Bank maintaining its Selic rate at 15%, the highest level since 2006, indicating a continued need for restrictive monetary policy. Foreign institutional investors sold 1.17 billion reais worth of Brazilian stocks on Tuesday, although domestic institutions purchased 2.43 billion reais, partially offsetting the outflows.

Broader Context and Implications

The political and trade tensions have significant implications for various sectors. The 50% U.S. tariff directly impacts Brazilian steel, aluminum, machinery, and auto parts industries, with estimates suggesting a potential $13 billion drop in Brazilian exports to the U.S. by 2026. Steel exports to the U.S. already dropped 23.6% in 2024. Industries like agribusiness, while not directly targeted by tariffs, face indirect risks from potential shifts in U.S. buyer preferences. Conversely, sectors less reliant on U.S. markets, such as renewable energy and technology, may prove more resilient.

The broader market implications include significant capital outflows, with Brazil recording $56.21 billion between January and October 2024. The Brazilian Real has depreciated 8% against the U.S. dollar in 2025, contributing to inflationary pressures. The spread between Brazil's bond yields and U.S. Treasuries has widened by 120 basis points since 2025, reflecting heightened risk premiums.

Expert commentary highlights a prevailing sentiment of "Uncertainty Tax," where political instability and unpredictable trade policies delay business investment and dampen consumer confidence. The Industrial Entrepreneur Confidence Index (ICEI) dropped to 46.1 in August 2025, its lowest level for the year. Legal conflicts, such as the U.S. Magnitsky sanctions targeting Brazilian Justice Alexandre de Moraes, further underscore the erosion of investor confidence in Brazil's economic sovereignty and the direct conflict between international and domestic legal frameworks.

Sectoral Performance and Technical Outlook

Within the Ibovespa, market breadth showed more declining stocks (562) than advancers (395), indicating broad-based selling pressure. However, some companies defied the trend: B3, the exchange operator, gained 4.3% on increased volatility, Embraer rose 2.17% on aerospace recovery expectations, and BTG Pactual advanced 3.2%. Conversely, energy firm Auren Energia plunged 3.89%, retailer C&A fell 3.70% under pressure from high interest rates, and banking giant Banco do Brasil dropped 3.18% on growth concerns following the GDP data.

Technical analysis for the Ibovespa reveals the index trading near critical resistance at 141,700 points, with the RSI indicator at 62.01 suggesting potential for further corrective moves. Support levels are identified at 139,300 and 138,000 points.

Looking Ahead

The coming days and weeks will be crucial for Brazilian markets. The conclusion of the Bolsonaro trial and any subsequent political ramifications will be closely watched. Investors will also monitor the appeal process for Trump's tariffs and the potential for new trade actions. Domestically, upcoming economic reports, such as Brazil's Service Sector Growth, along with U.S. Michigan Consumer Sentiment and Inflation Expectations, will further refine market expectations regarding monetary policy and commodity demand. The interplay of domestic political stability, global trade relations, and monetary policy adjustments will continue to shape the trajectory of Brazilian financial assets.
