Ibovespa Posts Biggest Daily Gain Since April

The Ibovespa jumped 1.8% to close at 177,356 on Wednesday, marking the benchmark’s biggest daily gain since early April, as easing oil prices and lower bond yields boosted risk appetite. Oil prices retreated after some ships managed to cross the Strait of Hormuz following 80 days of disruption, raising hopes that global supply conditions could gradually normalize. The pullback in crude prices helped ease inflation concerns and pushed bond yields lower, supporting financial stocks and the broader index. Itaú rose 2.3%, Bradesco gained 2.4%, and Itaúsa advanced 2.7%. Utilities also posted strong gains, with Auren Energia up 2.2%, Sabesp adding 2.1%, and Eneva climbing 4.1%. Other notable performers included Ambev (+2.6%) and Rede D'Or (+2.6%). In contrast, Petrobras fell 3.2% as oil prices declined.

The Ibovespa gained 1% to trade above the 176,000 mark on Wednesday as progress in US-Iran negotiations helped ease some inflation concerns despite still-elevated bond yields. Pakistan’s interior minister arrived in Tehran as part of mediation efforts after Pakistan hosted peace talks last month and continued conveying messages between both sides. Oil prices retreated, though they remained above $100 per barrel. Financial stocks advanced, with Itaú and Bradesco both rising more than 1%. Utilities also posted gains, with Axia climbing nearly 2%. Vale gained 1% after iron ore prices edged higher in China. Other notable performers included Ambev (+1.1%), Rede D'Or (+2.2%), and Embraer (+1.5%). In contrast, Petrobras fell nearly 1% as oil prices declined.

The Ibovespa fell 1.5% to close at 174,279 on Tuesday as investors reacted to a new election poll and persistent inflation concerns. An Atlas survey for Bloomberg showed Senator Flávio Bolsonaro losing support for October’s presidential election following reports linking him to former banker Daniel Vorcaro, who was charged with fraud. Meanwhile, oil prices remained elevated as markets looked past President Donald Trump’s decision to postpone attacks on Iran, keeping stagflation fears in focus. Brazil’s 10-year bond yield also moved higher, pressuring financial stocks. Banco do Brasil fell 0.93%, Bradesco lost 1.53%, Itaú Unibanco dropped 2.12%, and Santander Brasil slipped 0.37%. B3 plunged 4.96% after appointing Christian Egan as its new CEO, replacing Gilson Finkelsztain. Vale declined 1% on weaker iron ore prices in China, while Petrobras lost 0.75% as oil prices edged lower, though still above $100 per barrel.
