Ibovespa Defies US Tariffs as WEG and Vale Drive 2.44% Surge

The Brazilian stock market today staged a powerful rally, defying the immediate implementation of a 25% US tariff on a range of Brazilian goods. The benchmark Ibovespa today surged 2.44% to close at 177,547.56 points. Investors looking to invest in Brazil shrugged off the trade headwinds, focusing instead on stellar corporate earnings and robust operational previews from major B3 stocks. The market's resilience was further supported by a declining US dollar, with the USD/BRL currency pair closing lower at 5.05 reais.

Industrial giant WEG (WEGE3) was a primary catalyst for the day's gains, with its shares skyrocketing over 10% to 46.74 BRL. The rally followed a stronger-than-expected Q2 net profit of R$ 1.56 billion. Although the figure represented a minor 2.1% decline year-over-year due to domestic solar market softness, WEG’s return on invested capital (ROIC) improved to 33.6%. Additionally, its international revenue jumped 14.7% in US dollar terms, highlighting its strong global footprint.

Mining heavyweight Vale (VALE3) also fueled the market's upward trajectory, jumping 3.96% to close at 75.1 BRL. Investors reacted positively to Vale's Q2 operational preview, which reported iron ore production of 84.3 million metric tons—a 0.8% increase year-over-year and the company's highest second-quarter output since 2018. Vale's copper production also rose 6.3% to 98.4 kilotons, marking its best second quarter since 2017.

The broad-based rally extended to other heavyweights, including state-run oil firm Petrobras (PETR4), which rose 2.21% to 42.58 BRL as global oil prices climbed. Leading private lender Itaú Unibanco (ITUB4) edged up 0.87% to 42.9 BRL. The robust performance of these large-cap ADRs is expected to drive positive momentum for the broader Brazil ETF (EWZ). While the new 25% US tariffs impact up to $11 billion of Brazilian exports, the market found relief in key exemptions granted to major economic sectors, including beef, coffee, and aircraft.
